Answer:
w = 5 , w = -5
Step-by-step explanation:
w^2 = 25
Take the square root of each side
sqrt(w^2) = ± sqrt(25)
w = ±5
Answer:
5secs
Step-by-step explanation:
Given the equation of the height expressed ad;
h(t) = - 16t^2 + initial height
Given that initial height = 400feet
h(t) = - 16t^2 + 400
The waste will hit the ground at when h(t) = 0
substitute
0 = - 16t^2 + 400
16t^2 = 400
t² = 400/16
t² = 25
t = √25
t = 5secs
Hence it will take the easte 5secs to hit the ground
Answer:
D
Step-by-step explanation:
the perimeter of a shape is the sum of it's sides
in a square all sides have the same length
here all sides are 1 inch
so 1+1+1+1 = 4 inches which is D
F(x)=-3x
f(-5)=-3* (-5)
=15

Answer:
Step-by-step explanation:
Given
<em>Decimal Grid = Hundredths</em>
To solve for each:
We have:
For Amber:
For Grace:
This means that Grace shaded 60 of the hundredth models.
Decimal shaded is:
For Marsha:
Multiply this by 100, to get the number of shaded
This means that Marsha shaded 170 of the hundredth models.
Decimal shaded is:
