Answer:
2100 units
Step-by-step explanation:
We want to find the y-intercept of the function 
which can be used to model the height, y, of a parachute jumper x seconds after she jumps from an airplane.
To find the y-intercept, you substitute 
into the equation.
Multiply by zero to get:
Add zero to obtain:
'
Therefore the y-intercept, which is the initial height is 2100
Answer:
18in cubed
Step-by-step explanation:
area times height equals volume. so,
13.5×1⅓=18.
so, the volume is 18in cubed.
Answer:
-3x^2 - 21x
Step-by-step explanation:
This question is representing multiplying two functions :
We are finding f(x) * g(x)
We know that f(x) is -3x and g(x) is x + 7, therefore :
(-3x)(x + 7)
Follow FOIL :
First :
(-3x)(x)
-3x^2
Outer :
(-3x)(7)
-21x
Therefore the answer is :
-3x^2 - 21x
Answer:
12
Step-by-step explanation:
Use the PEMDAS
there is a parenthesis and exponents
9/3{(8) - 4)}
Multiply and divide 9/3= 3
Also subtract 8-4 = 4
3{8-4}
3(4)= 12
