PLEASEEE HELP<br> Questions 4 and 5

Ilya [14]

Answer:

Given and explained below.

question 4

using sine rule:

$\sf sinx = \frac{opp}{hyp}$

$\sf sinx = \frac{11}{13}$

$\sf x = sin^{-1}(\frac{11}{13} )$

$\sf x = 57.8$

question 5

using cosine rule:

$\sf cosx =\frac{adj}{hyp}$

$\sf cos(31) =\frac{x}{17}$

$\sf cos(31)*17 =x$

$\sf x = 14.6$

A dolphin jumps from the water at an initial velocity of 16 feet per second. The equation h + -16t^2 + 80t models the dolphin's

Dominik [7]

Answer:

100feet

Step-by-step explanation:

Given the height reached by a dolphin expressed by the equation is h = -16t^2 + 80t. At maximum height, the velocity is zero, hence;

v(t) = dh/dt = -32t + 80

0 = -32t + 80

32t = 80

t = 80/32

t = 2.5secs

Substitute t = 2.5 into the height formula h = -16t^2 + 80t

h = -16(2.5)^2 + 80(2.5)

h = -100+200

h = 100feet

Hence the maximum height the dolphin jumps is 100feet
