Answer:
a. 1.48 seconds
Step-by-step explanation:
You want to find the larger value of t such that h(t) = 10.
-16t^2 +25t +8 = 10
16t^2 -25t +2 = 0 . . . . subtract the left side to get standard form
Using the quadratic formula, we find the values of t to be ...
t = (-(-25) ± √((-25)^2 -4(16)(2)))/(2(16)) = (25±√497)/32
t ≈ 0.08 or 1.48
The ball goes in the hoop about 1.48 seconds after it is thrown.

<em>Additional comment</em>
The quadratic formula tells us the solution to ...
ax² +bx +c = 0
is given by ...
Here, we have a=16, b=-25, c=2. Of course, our variable is t, not x, but the relation is the same.
what you got to do is you have to pee X 2 which which will give you an answer and you will subtracted by 4 + 485 which will give u p xthen you have your answer you can do it backwards like pee times 485 + 14 * -2 equals P x
Answer:
y=3
Step-by-step explanation:
Using the formula, write in standard form.
hope i helped :) !! brainliest !?
Answer:6
Step-by-step explanation: It asking you for what is equivalent am I correct? So you have to be looking for the equivalent meaning (equal) decimal so the equivalent fraction shown but a decimal of the same fraction so the answer would be 6
Answer:
x = 7.55
Step-by-step explanation:
We can use the Pythagorean theorem to solve
a^2 +b^2 = c^2
where a and b are the legs and c is the hypotenuse
a^2 +8^2 = 11^2
x^2 +64 = 121
Subtract 64 from each side
x^2 +64-64 = 121-64
x^2 =57
Take the square root of each side
sqrt(x^2) = sqrt(57)
x = 7.549834435
To the nearest hundredth
x = 7.55
