Look at all the choices
we know that at t = 0, the height of the rock is 16
choices H and I do not have a value of 16 at t = 0.
H: h(0) = -5.2(0)² + 24(0) - 12 = -12
I: h(0) = -4.2(0)² + 26(0) - 20 = -20
so we are left with F and G
if we take choice F and plug in t = 1
h(1) = -4.7(1)² - 25(1) + 16 = -13.7
if we take choice G and plug in t = 1
h(1) = -4.7(1)² + 25(1) + 16 = 36.3
only choice G works for us since it has 36.3 at t = 1
you could have also put these points in a graphing calculator and then use the quadratic regression feature to get an equation that will model this data
Answer:
-5
Step-by-step explanation:
(-4-11)/(16-13) = -5
Y=7.26
To get this answer, you must isolate the y by subtracting 1.7 from both sides. On the left side, it cancels, and on the right side, you get 8.96-1.7, which simplifies to 7.26. So y=7.26
Answer:
-54
Step-by-step explanation: anything positive that u need the oppossite from its going to be the same number but negative
Answer:
F=70.7
Step-by-step explanation:
This is a simple substitution problem.
- The formula to change Fahrenheit to Celsius is
. - They give you C, so substitute it into the problem, which would give you
. - Simplify the right side of the equation by multiplying
by 21.5. - Now, add 32 to 38.7, which should have been your answer to the previous step.
- You should now have F= 70.7 as your answer.
