Step-by-step explanation:
Question 13The given diagram shows the height of the same cactus plant a year apart:
Year 1 height = 1.6 mYear 2 height = 2 mWe are told that the cactus continues to grow at the same percentage rate. To calculate the growth rate per year (percentage increase), use the percentage increase formula:
[tex]\begin{aligned}\sf Percentage \; increase &= \dfrac{\sf Final\; value - Initial \;value}{\sf Initial \;value}\\\\&=\dfrac{ 2-1.6}{1.6}\\\\&=\dfrac{0.4}{1.6}\\\\&=0.25\end{aligned}[/tex]
Therefore, the growth rate of the height of the cactus is 25% per year.
As the cactus grows at a constant rate, we can use the exponential growth formula to calculate its height in Year 6.
[tex]\boxed{\begin{minipage}{7.5 cm}\underline{Exponential Growth Formula}\\\\$y=a(1+r)^t$\\\\where:\\\phantom{ww}$\bullet$ $a$ is the initial value. \\ \phantom{ww}$\bullet$ $r$ is the growth factor (in decimal form).\\ \phantom{ww}$\bullet$ $t$ is the number of time periods.\\\end{minipage}}[/tex]
The initial value is the height in Year 1, so a = 1.6.
The growth factor is 25%, so r = 0.25.
As we wish to calculate its height in Year 6, the value of t is t = 5 (since there are 5 years between year 1 and year 6).
Substitute these values into the formula and solve for y (the height of the cactus):
[tex]\begin{aligned}y&=a(1+r)^t\\&=1.6(1+0.25)^5\\&=1.6(1.25)^5\\&=1.6(3.0517578125)\\&=4.8828125\\&=4.9\; \sf m\;(nearest\;tenth)\end{aligned}[/tex]
Therefore, if the cactus continues to grow at the same rate, its height in Year 6 will be 4.9 meters (to the nearest tenth).
Check by multiplying the height each year by 1.25:
Year 1 = 1.6 mYear 2 = 1.6 × 1.25 = 2 mYear 3 = 2 × 1.25 = 2.5 mYear 4 = 2.5 × 1.25 = 3.125 mYear 5 = 3.125 × 1.25 = 3.09625 mYear 6 = 3.09625 × 1.25 = 4.8828125 m[tex]\hrulefill[/tex]
Question 14The given diagram shows the height of the same snowman an hour apart:
Initial height = 1.8 mHeight after an hour = 1.53 mWe are told that the snowman continues to melt at the same percentage rate. To calculate the decay rate per hour (percentage decrease), use the percentage decrease formula:
[tex]\begin{aligned}\sf Percentage \; decrease&= \dfrac{\sf Initial\; value - Final\;value}{\sf Initial \;value}\\\\&=\dfrac{1.8-1.53}{1.8}\\\\&=\dfrac{0.27}{1.8}\\\\&=0.15\end{aligned}[/tex]
Therefore, the decay rate of the snowman's height is 15% per hour.
As the snowman melts at a constant rate, we can use the exponential decay formula to calculate its height after another 3 hours.
[tex]\boxed{\begin{minipage}{7.5 cm}\underline{Exponential Decay Formula}\\\\$y=a(1-r)^t$\\\\where:\\\phantom{ww}$\bullet$ $a$ is the initial value. \\ \phantom{ww}$\bullet$ $r$ is the decay factor (in decimal form).\\ \phantom{ww}$\bullet$ $t$ is the number of time periods.\\\end{minipage}}[/tex]
The initial value is the snowman's initial height, so a = 1.8.
The decay factor is 15%, so r = 0.15.
As we wish to calculate the snowman's height after another 3 hours, the value of t is t = 4 (i.e. the first hour plus a further 3 hours).
Substitute these values into the formula and solve for y (the height of the snowman):
[tex]\begin{aligned}y&=a(1-r)^t\\&=1.8(1-0.15)^4\\&=1.8(0.85)^4\\&=1.8(0.5220065)\\&=0.93961125\\&=0.9\; \sf m\;(nearest\;tenth)\end{aligned}[/tex]
Therefore, if the snowman continues to melt at the same rate, its height after another 3 hours will be 0.9 meters (to the nearest tenth).
Check by multiplying the height each hour by 0.85:
Initial height = 1.8 mHeight after 1 hour = 1.8 × 0.85 = 1.53Height after 2 hours = 1.53 × 0.85 = 1.3005Height after 3 hours = 1.3005 × 0.85 = 1.105425Height after 4 hours = 1.105425 × 0.85 = 0.93961125Related Questions

Serena is making a model of one of the Egyptian pyramids. The square base has sides that are all 4.4 in. Each of the triangular faces has a base of 4.4 in and a height of 3.8 in. How much paper would it take to cover the entire pyramid?
Answers
52.8 square inches of paper to cover the entire Pyramid.
The amount of paper needed to cover the entire pyramid, we need to determine the total surface area of the pyramid.
The pyramid consists of a square base and four triangular faces.
1. Base Surface Area:
The surface area of the square base can be calculated by finding the area of a square with sides measuring 4.4 inches. The formula for the area of a square is side length squared:
Base Surface Area = (4.4 in)² = 19.36 in²
2. Triangular Faces Surface Area:
Each triangular face of the pyramid has a base of 4.4 inches and a height of 3.8 inches. The formula for the area of a triangle is 1/2 times the base times the height:
Triangular Face Surface Area = 1/2 * (4.4 in) * (3.8 in) = 8.36 in²
Since the pyramid has four triangular faces, the total surface area of the triangular faces is:
Total Triangular Faces Surface Area = 4 * (8.36 in²) = 33.44 in²
3. Total Surface Area:
To calculate the total surface area of the pyramid, we add the base surface area to the total triangular faces surface area:
Total Surface Area = Base Surface Area + Total Triangular Faces Surface Area
= 19.36 in² + 33.44 in²
= 52.8 in²
Therefore, it would take approximately 52.8 square inches of paper to cover the entire pyramid.

Answers
Answer:
150 m²
Step-by-step explanation:
You want the total area of a figure consisting of a 12 m wide rectangle 5 m high with a triangle above that bringing the total height to 20 m.
Rectangle areaThe area of the rectangle is the product of its length and width:
A = LW
A = (12 m)(5 m) = 60 m²
Triangle areaThe area of the triangle is half the product of its base and height.
A = 1/2bh
A = 12/(12 m)(20 -5 m) = 90 m²
Total areaThe area of the whole figure is the sum of the areas of its parts:
total area = rectangle area + triangle area
total area = 60 m² +90 m² = 150 m²
The area of the figure is 150 m².
__
Additional comment
Since you know a triangle's area is equivalent to the area of a rectangle that has half the height, the 15 m high triangle can be considered as a rectangle 7.5 m high. Adding that to the 5 m area of the rectangle already there gives the equivalent area as that of a rectangle 12 m wide and 5+7.5 = 12.5 m high: (12 m)(12.5 m) = 150 m².

Find the equation of the axis of symmetry of the following parabola algebraically. y=−3x^2−42x−159
Answers
The equation of the axis of symmetry is x = -7.
Given is an equation of a parabola, y = -3x² - 42x - 159, we need to find the equation of the axis of the symmetry.
To find the equation of the axis of symmetry of a parabola in the form of y = ax² + bx + c, you can use the formula x = -b / (2a).
In this case, the given equation is y = -3x² - 42x - 159.
Comparing it to the general form, we have a = -3 and b = -42.
Applying the formula, we can calculate the x-coordinate of the vertex (the axis of symmetry):
x = -b / (2a)
x = -(-42) / (2(-3))
x = 42 / (-6)
x = -7
Therefore, the x-coordinate of the vertex is -7.
To find the equation of the axis of symmetry, we use the value of x in the form x = h, where (h, k) is the vertex.
Hence, the equation of the axis of symmetry is x = -7.

Which expressions are less than 7/8? Choose2 answers 7/8 x 9/19 7/8 x 3/4 7/8 x 9/9 7/8 x 4/3
Answers
The two expressions that are less than 7/8 are 7/8 x 9/19 and 7/8 x 3/4.
To determine which expressions are less than 7/8, we can compare them individually to 7/8 and evaluate their values.
Let's consider each expression one by one:
7/8 x 9/19:
To compare this expression to 7/8, we multiply the fractions:
(7/8) x (9/19) = 63/152.
Since 63/152 is less than 7/8, this expression is less than 7/8.
7/8 x 3/4:
Multiplying the fractions:
(7/8) x (3/4) = 21/32.
Since 21/32 is less than 7/8, this expression is less than 7/8.
7/8 x 9/9:
The fraction 9/9 simplifies to 1, so the expression becomes:
(7/8) x 1 = 7/8.
Since 7/8 is equal to 7/8 (not less than), this expression is not less than 7/8.
7/8 x 4/3:
Multiplying the fractions:
(7/8) x (4/3) = 28/24.
We can simplify 28/24 to 7/6.
Since 7/6 is greater than 7/8, this expression is not less than 7/8.
Therefore, the two expressions that are less than 7/8 are 7/8 x 9/19 and 7/8 x 3/4.

Answers
The correct options regarding the inequality are:
A. 1 hat, 1 scarf
D. 4 hats, 1 scarf
F. 2 hats, 1 scarf
How to explain the inequalityBased on the time constraint, Phil can spend a maximum of 12 hours knitting, so we can set up the following inequality:
2h + 3s ≤ 12,
Phil can knit at most 6 hats per week, because 6 hats * 2 hours/hat = 12 hours.
Phil can knit at most 4 scarves per week, because 4 scarves * 3 hours/scarf = 12 hours.
Phil can use at most 900 yards of yarn, because he has 900 yards of yarn.
Phil can knit 1 hat and 1 scarf, because 1 hat * 150 yards/hat + 1 scarf * 400 yards/scarf = 550 yards < 900 yards.
Phil can knit 4 hats and 1 scarf, because 4 hats * 150 yards/hat + 1 scarf * 400 yards/scarf = 900 yards.
Phil can knit 2 hats and 1 scarf, because 2 hats * 150 yards/hat + 1 scarf * 400 yards/scarf = 700 yards < 900 yards.

Find the degrees of freedom, alpha or significance level, and the t-critical value using the t-table n = 27 ;CL=98\%
Answers
The degrees of freedom for a sample size of 27 is 26, the alpha or significance level for a 98% confidence level is 0.02, and the t-critical value can be found using the t-table corresponding to a 98% confidence level and 26 degrees of freedom.
To find the degrees of freedom, alpha (significance level), and the t-critical value using the t-table, we need to consider the given information:
n = 27: This represents the sample size, which is 27 in this case.
CL = 98%: CL stands for the confidence level.
It indicates the level of confidence we want to have in our interval estimate.
In this case, the confidence level is 98%.
Degrees of Freedom (df): For a t-distribution, the degrees of freedom depend on the sample size.
Since we have a sample size of 27, the degrees of freedom would be n - 1.
Therefore, the degrees of freedom would be 27 - 1 = 26.
Alpha (α): Alpha, or the significance level, represents the probability of making a Type I error, which is rejecting a true null hypothesis.
The alpha level is determined by subtracting the confidence level from 1. In this case, the alpha level would be 1 - 0.98 = 0.02.
T-Critical Value: To find the t-critical value corresponding to a specific confidence level and degrees of freedom, we can consult the t-table. Since we have a confidence level of 98% and degrees of freedom of 26, we need to find the value that corresponds to the area of 0.01 (half of 1 - 0.98) in the t-distribution table.
The t-critical value would be the value from the table that matches these criteria.

The height if this trapezoid is 13.
Answer:
13cm
Step-by-step explanation:
The area of a trapezoid is given by the formula:
Area = ½*(b1+b2)*h
where:
b1 and b2 are the lengths of the bases of the trapezoid h is the height of the trapezoidIn this problem, we are given that b1 = 6 cm, b2 = 15 cm, and Area = 136.5 square centimeters.
Plugging these values into the formula, we get:
136.5 = ½*(6 + 15)*h
Solving for h, we get:
136.5=10.5h
h = 136.5/10.5=13centimeters
Therefore, the height of the trapezoid is 13 centimeters.

If you are traveling 14 miles per hour, how many inches would you travel in 3 seconds? (1 mile = 5280 feet; 1 foot = 12 inches) (Convert 3 seconds to inches)
Answers
1 mile = 5280 feet
1 foot = 12 inches
First, let's convert the speed from miles per hour to inches per hour:
14 miles/hour * 5280 feet/mile * 12 inches/foot = 14 * 5280 * 12 inches/hour
Next, we need to convert hours to seconds since we want the distance traveled in 3 seconds:
(14 * 5280 * 12 inches/hour) * (1 hour/3600 seconds) = 14 * 5280 * 12 * 1/3600 inches/second
Now, we can calculate the distance traveled in 3 seconds:
Distance = Speed * Time = (14 * 5280 * 12 * 1/3600 inches/second) * 3 seconds
Simplifying the expression:
Distance = (14 * 5280 * 12 * 3) / (3600) inches
Calculating the value:
Distance = 7392 inches
Therefore, if you are traveling at a speed of 14 miles per hour, you would travel 7392 inches in 3 seconds.
A population data set produced the following information N-250 Σx=9880, Σy=1456. Σxy-85080 Σx²=485870, Σy² = 135675 Find the value of oe and p²
Answers
The value of p² is approximately 0.999999528.
To find the value of oe (the standard error of estimate) and p² (the coefficient of determination), we can use the given population data set information.
The formula for the standard error of estimate (oe) is:
oe = √((Σy² - (Σy)² / N) / (N - 2))
Substituting the given values, we have:
oe = √((135675 - (1456)² / 250) / (250 - 2))
oe = √((135675 - 2124736 / 250) / 248)
oe = √(541.96)
oe ≈ 23.27
Therefore, the value of oe is approximately 23.27.
The coefficient of determination (p²) can be calculated using the formula:
p² = 1 - (Σxy - (Σx × Σy) / N) / ((Σx² - (Σx)² / N) × (Σy² - (Σy)² / N))
Substituting the given values:
p² = 1 - (85080 - (9880 × 1456) / 250) / ((485870 - (9880)² / 250) × (135675 - (1456)² / 250))
p² = 1 - (85080 - 14358080 / 250) / ((485870 - 968144 / 250) × (135675 - 2124736 / 250))
p² = 1 - (85080 - 57432.32) / (478352.56 × 123346.74)
p² = 1 - (27647.68) / (59022875580.02)
p² ≈ 0.999999528
Therefore, the value of p² is approximately 0.999999528.

Recta de pendiente 1⁄4 que pasa por (3,0).
Answers
The equation of the line with a slope of 1/4 that passes through the point (3,0) is y = 1/4x - 3/4.
To find the equation of a line with a slope of 1/4 that passes through the point (3,0), we can use the point-slope form of the equation of a line.
The point-slope form of a line is:
y - y1 = m(x - x1)
where (x1, y1) is the given point and m is the slope.
Substituting the values into the formula, we have:
y - 0 = 1/4(x - 3)
Simplifying:
y = 1/4(x - 3)
Distributing 1/4 throughout the expression:
y = 1/4x - 3/4
Therefore, the equation of the line with a slope of 1/4 that passes through the point (3,0) is y = 1/4x - 3/4.

7.5, 8.5, 14.5 are these can form a triangle?
Answers
No, the sides with lengths 7.5, 8.5, and 14.5 cannot form a triangle.
To form a triangle considering three lengths of sides, the sum of the lengths of any two sides must be greater than the length of the third side.
Checking the above condition
1. The sum of 7.5,8.5 is 16, which is greater than 14.5. So, the condition is satisfied.
2. The sum of 7.5, 14.5 is 22, which is greater than 8.5. So, the condition is satisfied.
3. The sum of 8.5 and 14.5 is 23, which is less than 7.5. The condition is not satisfied.
Since the sum of the two shorter sides 8.5 and 14.5 is not greater than the longest side 7.5 these three sides with given lengths cannot form a triangle.
Therefore, the sides with lengths 7.5, 8.5, and 14.5 cannot form a triangle.
