Answer:

y=-2x+12

Step-by-step explanation:

This is an equation in slope-intercept form:

y=mx+b (where m is the slope and b is the y-intercept)

We are given the slope, -2.

y=-2x+b

We plug in the values (5,2):

2=(-2)*5+b

2=-10+b

b=12

The equation is:

y=-2x+12

Answer:

None of these

Step-by-step explanation:

The two cases are for trigonometry special angles.

The cosine of an angle is given as the adjacent side length divided by the hypotenuse side length

Cos ∅ = A/H

1. The case of 45°,45°,90°

Cos x = 1 /√2

2. The case of 30°, 60° ,90°

Cos x = 1/2 or √3/2

the total cost after tax to repair Kimber’s cracked phone is represented by 00.4(30h)+30h Where h represents the number of hours

Serjik [45]

we have that

the total cost is

$0.040(30h)+30h$

In this equation the term 30h represent the cost due to h hours at at unit of 30

and the term 0.040(30h) is equal to calculate the 4% of (30h)

in this problem the tax rate is equal to 4%

therefore

<u>the answer is</u>

The term 0.040(30h) represents the amount of tax she must pay

A man standing on a lighthouse at a height of 124 feet sights two boats directly in front of him. One is at an angle of depressi

Ksivusya [100]

Answer:

$125\ ft$

Step-by-step explanation:

see the attached figure to better understand the problem

step 1

In the right triangle ABC find the length side BC

we know that

$tan(62\°)=\frac{124}{BC}$

$BC=\frac{124}{tan(62\°)}$

step 2

In the right triangle ABD find the length side BD

we know that

$tan(33\°)=\frac{124}{BD}$

$BD=\frac{124}{tan(33\°)}$

step 3

we know that

The distance between the two boats is the length side CD

$CD=BD-BC$

substitute the values

$CD=\frac{124}{tan(33\°)}-\frac{124}{tan(62\°)}=125\ ft$
