Answer:
103
Step-by-step explanation:
Evaluate 4k2 + 3
To evaluate 4k² + 3, when k = 5, which means when you sees k, put 5 in replacement
4k² + 3 = 4(5)² + 3
4(5×5) + 3
4(25) + 3
open the bracket
4 × 25 = 100
∴ 100 + 3 = 103

Answer:
32 feet
Step-by-step explanation:
0 seconds after launch, the rocket is still sitting on the tower. Its height is...
y = -16(0^2) +57(0) +32
y = 0 + 0 + 32 = 32
The rocket was launched from a tower 32 feet high.
Answer: Length of the radius of the sector is 6 units.
Step-by-step explanation:
Since we have given that
Length of an arc = 10.8
Radian of a central angle = 1.8
First we convert radian into degrees,

As we know the formula for "Length of an arc":

Hence, Length of the radius of the sector is 6 units.
So we know that the swimming pool is 15 by 7 meters wide.
15 times 7 is 105.
Now, a tile costs $6 and covers 1 square meter.
So, we should multiply 105 by 6, which would give us 630.
So, if I'm correct, the answer should be that it costs him $630 to install the tiles on the swimming pool.
(sorry if I'm incorrect)
