Select the correct answer. How many solutions for x does the following equation have? A. 4 B. 0 C. infinite D. 1

y = -x + 7

Slope-intercept form can give us valuable information about a graph.

Point-Slope Form

There are multiple ways to solve this problem; I am simply showing the way I use most often.

We can plug the known information into point-slope form and then simplify the equation into slope-intercept form. Point-slope is written as:

In this equation, y₁ and x₁ are the y and x values we are given and m is the slope. So, plug in the information.

Then, simplify the right side by distributing the -1.

Next, add 4 to both sides.

The equation in slope-intercept form is y = -x + 7.

Slope-intercept Form

Slope-intercept form is written as y = mx + b, where m is the slope and b is the y-intercept. So, our equation, y = -x + 7, shows that the slope is -1 and the y-intercept is 7. Using this information, we can compare the line to other linear functions or graph the line if needed.

Answer:

y = -x + 7 is your correct answer

The surface area of the given composite figure is: 484.38 cm²

The formula for the area of a rectangle is:

Area = Length * Width

The formula for the area of a square is:

Area = side * side

The surface area is simply the area of each of the surfaces of the figure.

Thus, surface area of the given composite figure is:

4(13 * 10) + (10 * 10) + (10 * 10) - 3π(5²))

The correct solution of the triangle is seen in option D

In this case, we would need to use the sine rule so as to solve the triangle as we have in the problem that is before us here. The sine rule states that;

a/Sin A = b/SinB = c/SinC

We know that we can be able to obtain the angle C using the sine rule;

29/Sin 42 = 33/SinC

SinC = 33Sin42/29

C = Sin-1(33Sin42/29)

C = 49.6 degrees

The angle B is now;

180 - (42 + 50)

B = 88.4 degrees

Then;

b/Sin 88 = 29/Sin42

b = 29 Sin 88/Sin42

b = 28.98/0.669

b = 43.3

Answer:

[tex]m_{perpendicular}[/tex] = 6

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

given

x + 6y = - 24 ( subtract x from both sides )

6y = - x - 24 ( divide through by 6 )

y = - [tex]\frac{1}{6}[/tex] x - 4 ← in slope- intercept form

with slope m = - [tex]\frac{1}{6}[/tex]

given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{-\frac{1}{6} }[/tex] = 6

The phrase, raise to the power of is used when referring to exponents because the power or strength increases with the addition of more numbers. For instance, 2 raised to the power of 1 is not as strong as 2 raised to the power of 100.

The usage of this phrase stems from the fact that numbers tend to increase in strength as they are raised to an increasing number of figures.  

The strength that numbers carry differs as they increase or decrease. Just as 10 is greater than 1 or 2, so will different powers of exponents differ in strengths.

Step-by-step explanation:

The 58th percentile of the lengths is 489.4 mm.

The 58th percentile of the lengths is calculated from normal distribution curve as shown below.

The mean of the distribution is at the 50th percentile.

The 58th percentile is between the mean and 1 standard deviation above the mean.

Mean (50%) = 480 mm

58% = ?

1 standard deviation above the mean (84%)= M + S.D = 480 mm + 40 mm = 520 mm

We are going to interpolate, to find the approximate value of the length.

50 ----- 480 mm

58 ----- ?

84 ------- 520 mm

(58 - 50)/(84 - 50) = (x - 480)/(520 - 480)

The given data results in the following Frequency Distribution

Class Frequency

21-27 3

28-34 8

35-41 7

42-48 8

49-55 4

In statistics, frequency distribution is a way of organizing data into categories, or intervals, and counting how many observations fall into each category. It helps us understand the distribution of data and identify patterns within it.

To construct a frequency distribution using 5 classes, we need to first determine the range of the data:

Range = Maximum value - Minimum value

= 52 - 21

= 31

We can then calculate the width of each class:

Width = Range / Number of classes

= 31 / 5

= 6.2

Since we cannot have a fractional width, we round up to the nearest whole number. The class width is therefore 7.

Next, we need to determine the class intervals, or boundaries, which are the values that define each class. We start with the minimum value and add the class width successively:

Class 1: 21-27

Class 2: 28-34

Class 3: 35-41

Class 4: 42-48

Class 5: 49-55

We can now count how many observations fall into each class. The resulting frequency distribution is shown below:

Class Frequency

21-27 3

28-34 8

35-41 7

42-48 8

49-55 4

In this frequency distribution, we can see that the majority of the observations fall into the middle three classes, with fewer observations in the first and last classes. This suggests that the data is roughly symmetric and evenly distributed around the center.

The quadratic function x² - 10x + 20 in vertex form is f(x) = (x - 5)² -5. The vertex of this parabola is (5, 15).

To convert the quadratic function in standard form, f(x) = ax² + bx + c, to vertex form, f(x) = a(x - h)² + k, where (h, k) is the vertex of the parabola, follow these steps:

Complete the square by adding and subtracting (b/2a)²inside the parentheses:

f(x) = x² - 10x + 20

f(x) = (x²- 10x + 25) - 5

Factor the expression inside the parentheses as a perfect square:

240° is the coterminal angle of 23×π÷3.

First, we can simplify 23 times π over 3 by noticing that 2π is equivalent to 6 pi over 3, so we can add 2π to 23 times pi over 3 until we get an angle between 0 and 2π (or 0 and 360 degrees).

23 times π over 3 is equivalent to an angle of 360 degrees times (23 times π over 3)/(2π), which simplifies to 360 degrees times 23/2, or 4140 degrees.

To find a coterminal angle between 0 and 360 degrees, we can subtract 360 degrees until we get an angle in that range.

4140 - 360(11) = 240

Therefore, a coterminal angle of 23 times pi over 3 between 0 and 360 degrees is 240 degrees.

The account will be worth approximately $13,268.58 in 20 years if it is opened with an initial deposit of $6,500 and earns 3.6% interest compounded semi-annually.

The formula accrued amount in a compounded interest is expressed as;

A = P( 1 + r/n )^( n × t )

Where A is accrued amount, P is principal, r is interest rate and t is time.

Given the data in the question;

Principal P = $6,500

Compounded semi-annually n = 2

Time t = 20 years

Interest rate r = 3.6%

Accrued amount A = ?

First, convert R as a percent to r as a decimal

r = R/100

r = 3.6/100

r = 0.036

Plug in the given values into the above formula.

A = P( 1 + r/n )^( n × t )

A = $6,500( 1 + 0.036/2 )^( 2 × 20 )

A = $6,500( 1 + 0.036/2 )^( 40 )

A = $6,500( 1 + 0.018 )^( 40 )

Answer:

Median: 31

Mode: 31

Range: 67

Step-by-step explanation:

Median: To find the median, we first need to arrange the numbers in order from smallest to largest:

25, 29, 31, 31, 69, 80, 92

The middle number is 31, so the median is 31.

Mode: The mode is the number that appears most frequently in the set. In this case, the number 31 appears twice, which is more than any other number. So, the mode is 31.

Range: The range is the difference between the largest and smallest numbers in the set. The smallest number is 25 and the largest number is 92, so the range is:

92 - 25 = 67.

Therefore, the median is 31, the mode is 31, and the range is 67.

Answer:

The median of the given set of numbers is 31, the mode is 31, and the range is 67.

Step-by-step explanation:

To find the median, we need to first arrange the numbers in order from smallest to largest:

25, 29, 31, 31, 69, 80, 92

There are seven numbers in the list, which means the middle number will be the fourth number: 31.
Therefore, the median is 31.

To find the mode, we need to determine which number appears most frequently in the list.
In this case, the number 31 appears twice, which is more than any other number in the list.

Therefore, the mode is 31.

To find the range, we need to subtract the smallest number from the largest number. The smallest number is 25 and the largest number is 92, so the range is:

92 - 25 = 67

Therefore, the range is 67.

If we use the variable n to represent the unknown number, then "15 more than twice a number" can be written as:
