Sorry don’t now the answer to this problem
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:
n > -2 or n < -3
Step-by-step explanation:
|2n+5| > 1
We have two solutions one positive and one negative. Remember to flip the inequality symbol for the negative
2n+5 > 1 or 2n+5 < -1
Subtract 5 from each side
2n+5-5 > 1-5 2n+5 -5 < -1 -5
2n >-4 2n < -6
Divide by 2
2n/2 > -4/2 2n/2 < -6/2
n > -2 or n < -3
Answer:
sin A =cos B
Step-by-step explanation:
sin A =opp/hyp =BC/AB
cos B=adj/hyp = BC/AB
