Write an equation of the parabola that passes through the point (62,−490) and has x-intercepts −8 and 72. Then find the average rate of change from x=−8 to x=2.
Answers
Answer:
y = 0.7(x^2 - 64x - 576)
Average rate of change = -49.
Step-by-step explanation:
As the x intercepts are -8 and 72 we can write the equation
y = a(x + 8)(x - 72) where a is some constant to be found.
As it passes through point (62, -490) we have, substituting:
-490 = a(62+8)(62-72)
-490 = - 700a
a = 0.7
So the equation of the parabola
y = 0.7(x + 8)(x - 72) or
y = 0.7(x^2 - 64x - 576).
Average rate of change between x = -8 and x = 2
= [0.7(2+ 8)(2 - 72) - 0.7(-8+8)(-8-72)] / (2 - -8)
= -490 - 0 /10
= -49

Select the slope and y-intercept of the relationship shown in the table
Answers
Answer:
slope = 0.05, y-intercept = 2,000Hence, option A is true.
Step-by-step explanation:
x y
10, 000 2,500
20, 000 3,000
30, 000 3, 500
Taking two points (10000, 2500) and (20000, 3000) to find the slope between the points
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\frac{3000-2500}{20000-10000}[/tex]
[tex]m=\frac{1}{20}[/tex]
[tex]m=0.05[/tex]
We know that the slope-intercept form of the line equation is
[tex]y=mx+b[/tex]
where 'm' is the slope and 'b' is the y-intercept
substituting the point (10000, 2500) and m=0.05 in the slope-intercept form
[tex]y=mx+b[/tex]
[tex]2500\:=\:0.05\left(10000\right)+b[/tex]
[tex]500+b=2500[/tex]
[tex]b=2000[/tex]
Thus, the y-intercept is: b=2000
Thus,
slope = 0.05, y-intercept = 2,000Hence, option A is true.

Reflect triangle ABC over the x-axis. Then translate the new triangle 5
units to the left. What are the coordinates of the vertices of the final image?
Answers
Answer:
The coordinates of the vertices of the final image will be:
A''(-6, 8), B''(-7, -2), and C''(0, -2)
Hence, option (B) is true.
Step-by-step explanation:
Given the triangle with the vertices
A(-1, -8)B(-2, 2)C(5, 2)We know that when we reflect a point across the x-axis, the x-coordinate remains the same, but the y-coordinate reverses its sign.Thus,
The rule of reflection across the x-axis:
(x, y) → (x, -y)
so
A(-1, -8) → A'(-1, -(-8)) = A'(-1, 8)
B(-2, 2) → B'(-2, -2) = B'(-2, -2)
C(5, 2) → C'(5, -2) = C'(5, -2)
Then, translate the new triangle 5 units to the left
Rule of translating 5 units to the left
(x, y) → (x-5, y)
so
A'(-1, 8) → A''(-1-5, 8) = A''(-6, 8)
B'(-2, -2) → B''(-2-5, -2) = B''(-7, -2)
C'(5, -2) → C''(5-5, -2) = C''(0, -2)
Therefore, the coordinates of the vertices of the final image will be:
A''(-6, 8), B''(-7, -2), and C''(0, -2)
Hence, option (B) is true.

A. Both systems have an infinite number of solutions
B. The system of equations has more solutions
C. The system of inequalities has more solutions
D. Both systems have only one solution
Answers
Answer:
the answer is C, NOT B
Step-by-step explanation:
The system of inequalities will have more solutions than the system of equations , Option C is the corrrect answer.
What are Inequalities ?Inequality is the relation between two unequal numbers or algebraic expression.
The inequality symbols are less than , greater than , less than equal to, greater than equal to.
It is given in the question that
the system of equations y= -1/2x + 1 and y = x - 5.
the system of inequalities y > -1/2x + 1 and y < x - 5.
x-5 = -1/2 x +1
2x+x=6*2
3x = 12
x = 4
x-5 >-1/2 x +1
x>4
The system of inequalities generally have more solutions and in this case definitely have more solutions than the system of equations.

[tex]Area = 25*(10 + w) + 13.5(10 + w)[/tex]
Step-by-step explanation:
Given
Stores and Parking Lots
Required
Determine the area as a sum of area of stores and area of parking lots
First, calculate the area of the stores
The dimension of store A is: 25 by 10
The dimension of store B is: 25 by w
The dimension of stores A and B (as an entity) is: 25 by 10 + w
The area is then calculated as:
[tex]Area = 25 * (10 + w)[/tex] -------- A1
Next, calculate the area of the parking lots
The dimension of parking lot A is: 13.5 by 10
The dimension of parking lot B is: 13.5 by w
The dimension of parking lots A and B (as an entity) is: 13.5 by 10 + w
The area is then calculated as:
[tex]Area = 13.5 * (10 + w)[/tex] -------- A2
The area of the shopping center is then calculated as:
[tex]Area = A_1 + A_2[/tex]
[tex]Area = 25*(10 + w) + 13.5(10 + w)[/tex]
