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

Find the value of x that makes lines u and v parallel
gogolik [260]

Answer:

x = 4 for Lines U and V to be parallel

<u>Skills needed: HS Geo, Angle Theorems, Equations</u>

Step-by-step explanation:

1) We see that there are two angle measures given to us. There is an angle marked with the measure of 130°, and the other is marked with (33x-2)°.

  • First of all, these two angles are categorized alternate interior angles. They are on alternate sides of the transversal, and are within the two lines (not on the outer side of the lines). I will add an image for reference regarding this idea.
  • If 2 lines are parallel, alternate interior angles are congruent. This means that: 33x-2=130

2) Solving this equation is fairly straightforward.

  • 33x-2+2=130+2 (add 2 to both sides in order to get the 33x by itself.
  • 33x\div33=132\div33 (to get x by itself)
  • 132 divided by 33 is 4, and 33x divided by 33 is x, so x=4
