Use the cosine formula

Cos(angle) = adjacent/ hypotenuse


cos(30) = x/8

Cos(30) can be written as sqrt(3)/2

Now you have :

sqrt(3)/2 = x/8

Multiply both sides by 8:

X = sqrt(3)/2 x 8

Simplify:

X = 4sqrt(3)

Which is the graph of y = cos(x) + 3?
Paha777 [63]

Answer:

On a coordinate plane, a cosine curve has a maximum of 4 and a minimum of negative 2.

Step-by-step explanation:

Given: y=\cos x+3

To find: maximum and minimum of the cosine curve

Solution:

A coordinate plane is a two-dimensional plane formed by the intersection two axis: x-axis and y-axis.

These two axes are perpendicular to each other.

As per the image drawn below,

a cosine curve has a maximum of 4 and a minimum of negative 2 on the coordinate plane.

A water balloon is thrown out of a window 96 feet above the ground. The balloon is traveling downward at 16 feet per second init
Marysya12 [62]

Answer:

3 seconds.

Step-by-step explanation:

Since we are figuring out when the water balloon will hit the ground, y will need to be equal to 0.

0 = - 16t² - 16t + 96

Now we simply factor the trinomial to find t.

0 = -16(t² - t - 6)

0 = (t - 3)(t + 2)

t - 3 = 0 ⇒ t = 3

t + 2 = 0 ⇒ t = -2

Since we are referring to time, we need to use the positive value. Therefore, the water balloon will take 3 seconds to hit the ground.

A car travels 370 1/2 miles in 6 1/2 hours what is the average speed at which the car is traveling
Alex

Answer:

57 miles per hour

Step-by-step explanation:

Speed is equal to distance over time

I changed the fractions to decimals for ease of math

distance = 370 .5 miles

time = 6.5 hours

Speed = 370.5/6.5 = 57 miles/hour
