Answer:
50.2 m²
Step-by-step explanation:
The area (A) of a circle is calculated as
A = πr² ( r is the radius , here r = 4 ), thus
A = π × 4² = 16π = 16 × 3.14 ≈ 50.2 ( to the nearest tenth )
Answer:
7.4
Step-by-step explanation:
I did this before that's how I know
Answer:
160002 feet
Step-by-step explanation:
y(t)=-16t^2+3200t+2
We need y’ to find a maximum
y’(t)=-32t+3200
y’(t)=0 if t=100
Notes that y’(t)>0 if t<100, and fot t>100 y’(t)<0. Now we can conclude that y(t) has maximum in t=100
Y(100)=-16*10000+3200*100+2
Y(100)=160002 feet
Answer:
x=5 and y=8
Step-by-step explanation:
Find x:
3x - 2 = x + 8
-x -x
2x - 2 = 8
+2 +2
2x = 10
---- ----
2 2
x = 5
Find y:
6y - 7 = y + 33
-y -y
5y - 7 = 33
+7 +7
5y = 40
---- -----
5 5
y = 8
