Answer:
The height is 10
Step-by-step explanation:
500 ÷ 2 1/2 ÷ 20 = H
25 ÷ 2 1/2 = H
H = 10
Answer:
The given equation will have value less than 100 whenever the value of b is greater than 12.89
Step-by-step explanation:
For the given equation, p(b) = 520 × 
to have a value less than 100 we can establish inequality as:
p(b) < 100
or, 520 × < 100
or, 
× < 
or, < 
or, ㏒ ( ) < ㏒ ()
or, b× ㏒ 0.88 < ㏒ ()
or, 
< b
or, 12.89 < b
Hence for the equation to have value less than 100, b must be greater than 12.89.
Depreciation is the decrease in value of a given asset within a given period of time.
Using the formula, A=P(1-r/100)^n, where A is the new value after depreciation, P is the original value, r is the depreciation rate and n is the time taken.
Therefore,
A = 24500(0.8525)^14
= 2623.54 dollars
≈ 2623.50 dollars
Thus the value after 14 years will be 2623.50 dollars
Using linear function concepts, it is found that lines are parallel if they have the same slope.
<h3>What is a linear function?</h3>
A linear function is modeled by:
y = mx + b
In which:
- m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
- b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.
Parallel lines have the same inclination, that is, if two lines are parallel, they have the same slope.

Step-by-step explanation:
let eqn be y = mx + b
since parallel, the lines have same slope
so, m = -3x
sub (-4 , 5):
5 = -3(-4) + b
b = -7
therefore, eqn is y = -3x - 7
