Step-by-step explanation:
Answer:
1: X= 8, 2: 2/5 or 0.4
Step-by-step explanation:
1: 2(2x + 1) + x = x + 2x + 18
5x + 2 = 3x + 18
2x = 16
x = 8
2: 2x + x + 2x = 10 + x
5x = 10 + x
4x = 10
x = 4/10
x = 2/5
x = 0.4
Answer:
180feet
Step-by-step explanation:
Given the function that models the height of a ball
s(t) = 144 + 48t − 16t^2.
At maximum height, the velocity is zero ie. ds/dt = 0
ds/dt = 48 - 32t
0 = 48 - 32t
48 = 32t
t = 48/32
t = 1.5secs
Get the maximum height
s(t) = 144 + 48t − 16t^2.
s(1.5) = 144 + 48(1.5)-16(1.5)^2
s()1.5) = 144 + 72 - 16(2.25)
s(1.5) = 144 + 72-36
s(1.5) = 180 feet
Hence the maximum height attained by the ball is 180feet
Ratio 1:5....added = 6
complimentary angles, when added, = 90 degrees
1/6(90) = 90/6 = 15
5/6(90) = 450/6 = 75
so ur 2 angles are : 15 and 75
Answer:
The first one is correct
Step-by-step explanation:
You can multiply the base and perpendicular height to find the area.
