Answer:
5
Step-by-step explanation:
balls + sports towels = Total
(3 * 6) + (8x) = 65
18 + 8x = 65
8x = 47
x = 5.875
Cannot buy .875 of a towel so answer has to be rounded down to 5 towels.
Answer:
All Real Numbers
Step-by-step explanation:
g(t) = (t − 7)(t + 6)
= t^2 - t - 42
This is a parabola which opens upwards.
The domain is All Real Numbers
Answer:
T = 1.5s
Step-by-step explanation:
Hello,
To find the time the pincone hits the ground, we need to use the equation given.
Note that h = 0 when the pinecones hits the ground.
This question relates to motion under gravity.
h = -16t² + 36
0 = -16t² + 36
Make t² the subject of formula
16t² = 36
t² = 36 / 16
t² = 2.25
Take the square root of both sides
t = √(2.25)
t = 1.5s
The time it takes the pinecone to hit the ground is 1.5s.
Answer: 17 inches
Explanation: so we have a triangle with the two side lengths 8 and 15 and we’re trying to find the hypotenuse. so using the pythagorean theorem, we have 8^2 + 15^2 = c^2. when we solve we get 64 + 225 = c^2, which is 289 = c^2. next, we find the square root of both sides and c = 17 inches.
hope this helped!
