Answer:
5x²-7x+2
step by step explanation:
(f•g)(x) = f(x)•g(x)
(x-1)•(5x-2)
x×5x-2x-5x-1×(-2)
5x²-2x-5x+2
=5x²-7x+2
Answer:
The above function value for shows that height of the ball before it was dropped i.e. at time = 0 seconds.
The height of the ball above the ground before it was dropped = 400 ft.
Step-by-step explanation:
Given:
The quadratic function that models the height of the baseball above the ground in feet , seconds after it was dropped is given as:
To find and interpret the meaning of the function value in contect of the problem.
Solution:
In order to find , we will replace in the given function as is a function of time .
Thus, we have:
(Answer)
The above function value for shows that height of the ball before it was dropped i.e. at time = 0 seconds.
The height of the ball above the ground before it was dropped = 400 ft.
Answer:
X = 27
Step-by-step explanation:
a right is 90 so take 63 from the 90 and you
get 27
Answer:
1) Slope: 3; y-intercept: -7
2) Slope: 2/3; y-intercept: 1
Step-by-step explanation:
y = mx + b; m is slope and b is y-intercept
1. y = 3x - 7
The equation is already in slope-intercept form, so you can find the slope and intercept.
Slope: 3
y-intercept: -7
2. y - 1 = 2/3x
For this one, you have to convert this into slope-intercept form (solving for y)
y - 1 = 2/3x
Add 1 to both sides
y - 1 + 1 = 2/3x + 1
y = 2/3x + 1
Now that the equation is in slope-intercept form, you can get the slope and y-intercept.
Slope: 2/3
y-intercept: 1
