Answer:
y - 1 = -(x - 2)
Step-by-step explanation:
y - y1 = m(x - x1)
m = (5-1)/(-2-2) = 4/-4 = -1
Using any one coordinate, construct
y - y1 = m(x - x1)
y - 1 = -1(x - 2)
Answer:
880
Step-by-step explanation:
2/5 times 2200
Answer:
12 hours
Step-by-step explanation:
Full time job:
Earning per week = $475
Part time job :
Earning per hour = $11
Number of working hours per week at per time job to increase weekly earning to atleast $600 ;
Let number of hours = h
Full time earning + earning per hour * (number of hours) ≥ 600
$475 + ($11 * h) ≥ 600
$475 + $11h ≥ 600
11h ≥ 600 - 475
11h ≥ 125
h ≥ 125 / 11
h ≥ 11.36
Hence, sharia will need to work for 12 hours per week

Trigonometric ratios are useful in calculating the side lengths of a triangle.
- The length of the zip line is 222.5 ft
- The height where the ladder rests against the tree is 38.6 ft
- The distance between the base of the ladder and that of the tree is 10.4 ft
- The distance between the base of the tree and the spot where the zip line is anchored to the ground is 219.1 ft
<u>(a) Length, z</u>
First we calculate (h) using the following sine ratio

Make h the subject

Next, we calculate (z) using the following sine ratio

Make z the subject

Substitute 


Hence, the length of the zip line is 222.5 ft
<u>(b) The height, h</u>
In (a), we have

Evaluate

Hence, the height where the ladder rests against the tree is 38.6 ft
<u />
<u>(c) The distance, b</u>
To do this, we make use of the following sine ratio

Make b the subject


Hence, the distance between the base of the ladder and that of the tree is 10.4 ft
<u />
<u>(d) Distance, B</u>
To do this, we make use of the following sine ratio

Make B the subject

Substitute 


Hence, the distance between the base of the tree and the spot where the zip line is anchored to the ground is 219.1 ft
