The graph below represents slope as a rate of change
Which is the slope of the line shown?
A. 4.8
B. -3
C. -2/3
D. 2/3
Answer:
D. 2/3
Step-by-step explanation:
Two distint points on the graph are
(0, -3) and (6, 1)
Slope = (rise in y) / (run in x)
Rise:
y goes from -3 to 1
rise = 4
Run
x goes from 0 to 6
run = 6
Slope = 4/6
reduce
Slope = 2/3
Find the area of the triangle
Answer:
32 m^2
Step-by-step explanation:
Area = 8 x (2 + 6) x 1/2
Area = 8 x 8 x 1/2
Area = 64 x 1/2
Area = 32
Hope that helps! :)

Answer:
32
Step-by-step explanation:
formula for area of a triangle = [tex]A=\frac{bh}{2}[/tex]
where b = base length and h = height
The triangle shown has the following the dimensions
base length = 2 + 6 = 8m
height = 8m
Using these dimensions we plug in the values into the formula
[tex]A=\frac{8*8}{2} \\8*8=64\\\frac{64}{2} =32[/tex]
Hence, the area of the triangle is 32 square meters

Find the area of the figure above.
[?] cm2
Answer:
We first ALWAYS have to split the figure apart from each other,
lets split it into a triangle and a square!
Let's find the area of the triangle:
20(height) x 20(base) = 400!
400 x 1/2 (just dividing by 2) = 200!
*Remember* Formula of a triangle is:
B(base) x H(height) x 1/2 (basically dividing by 2)
Now time to find the area of the square!
20 x 20 = 400!
Now let's add both their areas:
400 + 200 = 600!
Step-by-step explanation:
600cm2 is your answer.
The figure has an area of 600 square centimeters.
In this question we need to determine the area of the entire figure, this area is the sum of the areas of a square and two symmetric right triangles, defined by respective formulas, that is:
[tex]A = A_{s} + 2\cdot A_{t}[/tex] (1)
Where:
[tex]A[/tex] - Total area, in square centimeters.[tex]A_{s}[/tex] - Square area, in square centimeters.[tex]A_{t}[/tex] - Triangle area, in square centimeters.By applying area formulas for squares and triangles, we expand (1):
[tex]A = x^{2} + \frac{1}{2}\cdot x\cdot y[/tex] (2)
Where:
[tex]x[/tex] - Side length of the square, in centimeters.[tex]y[/tex] - Height of the two right triangles, in centimeters.If we know that [tex]x = 20\,cm[/tex] and [tex]y = 20\,cm[/tex], then the area of the figure is:
[tex]A = \frac{3}{2}\cdot (20\,cm)^{2}[/tex]
[tex]A = 600\,cm^{2}[/tex]
The figure has an area of 600 square centimeters.

Tiffany and Dion are having a walking race. The equation and graph show the distance each person is from the starting line,
Tiffany's Distance
d = 2.5t, where d is the distance, in yards that Tiffany is from the starting line after t seconds
PLEASE ANSWER A., B. And C.
Answer:
Step-by-step explanation:
Tiffany's distance is defined by the equation,
d = 2.5t
Here, d = distance of Tiffany from the starting line
t = time
a). d = 2.5t
[tex]\frac{d}{t}=2.5[/tex]
Tiffany's rate = 2.5 yards per second
b). Since, slope of a line passing through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by,
Slope = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
Therefore, slope of the line passing through two points (0, 10) and (10, 35)
= [tex]\frac{35-10}{10-0}[/tex]
= 2.5 yards per second
Dion's walking rate = 2.5 yards per second
Equation that defines the distance of Dione,
d = mt + b
Here, m = rate of the walking by Dione
b = y-intercept
Hence, equation will be,
d = 2.5t + 10
c). If d = 60 yards
For Tiffany,
d = 2.5t
60 = 2.5t
t = 24 seconds
For Dion,
d = 2.5t + 10
60 = 2.5t + 10
2.5t = 50
t = 20 seconds
Therefore, Dion will take less time and finish first.

Answer:
(x + 2)² = 9
x = 1 or - 5
Step-by-step explanation:
x² + 4x - 5 = 0
Solving first using completing the square method
x² + 4x = 5
x² + 4x + (4/2)² = 5 + (4/2)²
x² + 4x + 2² = 5 + 2²
x² + 4x + 4 = 5 + 4
x² + 4x + 4 = 9
Factorise
x² + 2x + 2x + 4 = 9
x(x + 2) + 2(x + 2) = 9
(x + 2)(x + 2) = 9
(x + 2)² = 9
Square root both sides
√(x + 2)² = √9
x + 2 = ± 3
x + 2 = +3
x = 3 - 2
x = 1
x + 2 = -3
x = -3 - 2
x = -5
Hence, x = 1 or - 5

NEED HELP ASAP!!! EASY QUESTION :)
some body have asked this question I have forgotten the name the question is: the circumference of a circle is 36π cm what is the radius of a circle if any body finds it then please answer him or her
The formula for the area of a circle is given by A = πr², where r is the radius of the circle.
Since we know that area A = 36π, we can substitute into the formula for area A and get:
36π= πr²
Now, dividing both sides by π in order to begin isolating r on one side of the equation, we get:
(36π)/π = (πr²)/π
36(π/π) = (π/π)r²
36(1) = (1)r²
36 = r²
r² = 36 (since equality is symmetric, i.e., if a = b, than b =a)
Now, taking the square root of both sides, we have:
√(r²) = ±√(36)
r = √(36) (since a distance cannot be physically negative, then we have to use the positive square root)
r = 6 (since (6)(6) = 36)
CHECK:
A = 36π
36π= π(6²)
36π = π(36)
36π = 36π
Therefore, r = 6 is indeed the radius of the circle with an area of 36π.
Answer:
The radius of the circle is 6.
Explanation:
Take the square root of 36.

Answer:
sin Z = 4/5
sin C = 24/25
cos A= 4/5
tan Z = 4/3
Step-by-step explanation:
1.)sin Z = O/H
sin Z = 36/45 = 4/5
sin Z = 4/5
2.)sin C = O/H
sin C = 48/50 = 24/25
sin C = 24/25
3.)cos A = A/H
cos A = 40/50 = 4/5
cos A= 4/5
4.)tan Z = O/A
tan Z = 24/18 = 4/3
tan Z = 4/3

A right triangle has side lengths 8 ,15 , 17 and as shown below.
Use these lengths to find TanA, sinA,cosA
Answers:
tan(A) = 8/15
sin(A) = 8/17
cos(A) = 15/17
==================================================
Explanation:
The tangent ratio involves the opposite over adjacent. With respect to angle A, the opposite side is 8 units long as this side is as far as possible away from angle A. In contrast, the adjacent side is 15 units long because this leg is closest possible and the two are right next to one another.
Therefore,
tan(angle) = opposite/adjacent
tan(A) = BC/AC
tan(A) = 8/15
---------------
As for the other trig ratios, they are:
sin(angle) = opposite/hypotenuse
cos(angle) = adjacent/hypotenuse
which explains why sin(A) and cos(A) are 8/17 and 15/17 respectively.
An adult takes 400 mg of ibuprofen. Two hours later, there is 201.6 mg of
ibuprofen left in the persons system. How long will it take until there is only 25 mg
of ibuprofen left in the person's system? Show all work and round your answer to
three decimal places.
Answer:
It will take 3 hours 46 minutes and 8 seconds to use 375 mg of ibrufen.
Step-by-step explanation:
An adult takes 400 mg of ibuprofen. Two hours later, there is 201.6 mg of
ibuprofen left in the persons system
This means that in 2 hours time
400- 201.6= 198.4 mg was used up.
We need only 25 mg in the system
so 400- 25= 375 mg time is needed
time mg
2 hour 198.4
x 375
Using the cross product rule
x= 375*2/198.4
x= 3.780 hrs
Which means 3 hours and (0.78* 60)= 46.8 minutes.
It will take 3 hours 46 minutes and 8 seconds to use 375 mg of ibrufen.
A computer program found that the line y=3x - 52 is the best line of best fit to represent the temperature outside and the amount of ice cream sold on the beach. If the temperature is predicted to be 70 degrees tomorrow, how much ice cream can they expect to sell?
Answer:
158
Step-by-step explanation:
given x = 70
=> y = 3(70) -52 = 210 -52 = 158
the ice cream they can expect to sell = 158
Write the polynomial in standard form then name the polynomal based on its degree and number of terms 2-11x2-8x + 6x2
Write the polynomial in standard form then name the polynomal based on its degree and number of terms 2-11x²-8x + 6x²
Answer:
Standard form: -5x²- 8x + 2
name: Quadratic polynomial
Step-by-step explanation:Given polynomial
2-11x²-8x + 6x²
To write this polynomial in standard form,
i. First simplify it
Collect like terms
2 - 11x² + 6x² - 8x
Add the second and fourth terms
2 - 5x² - 8x
ii. Arrange the terms in the polynomial in order of decreasing order of x.
In other words, the term which has the highest order of x is written first followed by the term with the next highest order of x and so on.
In this case, the term with the highest order of x is the second term which is given by -5x² followed by -8x and then 2.
Therefore, the standard form of the given polynomial is
-5x²- 8x + 2
The degree of a polynomial which is in standard form is the order of its first term.
In this case, the order of the first term is 2. This means that the degree of the polynomial is 2.
Since the degree of the polynomial is 2 and it has three terms, this is a quadratic polynomial.
