Jason jumped off of a cliff into the ocean in Acapulco while vacationing with some friends. His height above ocean measured in f
lbvjy [14]

Answer:

480 feet.

Step-by-step explanation:

We are told that the function h(t)=-16t^2+16t+480 models Jason's height above ocean measured in feet as a function of time and t is the time in seconds from jumping off.

To find the height of cliff we need to substitute t=0 in our given function as at t=0 we will get Jason's height above ocean which is same as the height of the cliff.

Upon substituting t=0 in our function we will get,

h(0)=-16(0)^2+16*0+480

h(0)=-0+0+480

h(0)=480

Since, the function gives Jason's height above ocean in feet, therefore, the cliff was 480 feet high.

Imagine two lines intersect. How can the properties of linear pairs and vertical angles help to determine the angle measures cre
Vikentia [17]

Answer:When two lines intersect they form two pairs of opposite angles, A + C and B + D. Another word for opposite angles are vertical angles. Vertical angles are always congruent, which means that they are equal. Adjacent angles are angles that come out of the same vertex.

Solve for x. The triangles in each pair are similar please question number 14
Brilliant_brown [7]

Given that the triangle CDE is similar to triangle CML, it means that the ratio of their corresponding sides are equal. It means that

CD/CM = DE/ML = CE/CL

CD = 20 + 12x + 2 = 12x + 22

CE = 30 + 12 = 42

20/12x + 22 = 12/42

By cross multipying, it becomes

12(12x + 22) = 20 * 42

144x + 264 = 840

144x = 840 - 264 = 576

x = 576/144

x = 4
