(b)60 by 25%
60(1+0.25)=75
(c)80 by 75%
80(1+0.75)=140
(e)110 by 60%
110(1+0.6)=176

One of the roots of the equation 5x^2-36x+t=0 is five times as big as the other root. Find the value of t.
Answers
Answer:
t = 36
Step-by-step explanation:
If you divide the equation by 5, you have ...
x^2 -7.2x +t/5 = 0
The opposite of the sum of the roots is the coefficient of the linear term, so is 7.2. If the roots are "r" and "5r", then their sum is r+5r = 6r, so the value of r is.
7.2/6 = 1.2
The roots are 1.2 and 5·1.2 = 6.
The constant term t/5 is the product of the roots, so ...
t/5 = 1.2 · 6
t = 6·6 = 36 . . . . . multiply by 5

Question 5
Find the slope of the line that goes through the points (-2, -1) & (-1,-2)
Answers
Answer:
-1
Step-by-step explanation:
solution:
(-2 , -1) = (x1 , y1)
(-1 ,-2) = (x2 , y2)
we know that,
slope = (y2 - y1)/(x2 - x1)
=(-2 - -1)/ (-1 - -2)
=(-2 + 1) / (-1 + 2)
= -1/1
=-1
slope = -1
The height, h, of an object that is thrown upwards into the air can be represented as h = 0.5at2 + v0t + h0, where a represents the acceleration due to gravity (– 32 ft/s)
2), v0 represents the initial velocity, in feet per second, h0 represents the initial height of the object, in feet, and t represents time, in seconds.
Part A:
A ball thrown upwards from the top of a 64–ft high building with an initial velocity of 48
ft/s.Write an equation that could be used to determine the time, t, in seconds, for the ball to reach the ground. Assume ground level is at a height of 0 ft.
Part B:
Determine the time, t, in seconds, that takes the ball to reach the ground and explain how you determined your answer.

Line segment AB is 14 units long. If the line segment AB is reflected in the x-axis to form A'B', How many Units long will A'B' be?
Answers
As the line segment AB is reflected in the x-axis to form A'B', A'B' will be 14 unit long.
What is reflection?A reflection is referred to as a flip in geometry. A reflection is the shape's mirror image. A line, called the line of reflection, will allow an image to reflect through it.
Every point in a figure is said to reflect the other figure when they are all equally spaced apart from one another. The reflected picture should have the same size and shape as the original, but it faces the opposite way. Changes in position during contemplation may also result in translation.
Given length of the line segment AB is 14 unit.
Then, after reflection in the x-axis, line segment AB forms A'B'.
As the reflected picture should have the same size and shape as the original, length of the line segment A'B' will be 14 unit.

The slope of the line is 3/4. Find the rise if the run is 8.
Answers
Answer: Rise is 6
Step-by-step explanation:
3=rise and 4 is run so if run becomes 8 then rise is 6
Step-by-step explanation:
Slope is defined as rise over run.
[tex]m = \frac{y}{x}[/tex]
if the slope (m) is 3/4, and the rise (y) is 8, you might substitute those values into the equation and solve for x.
