The speed of the walker is 16.67 miles per hour.
The speed of the cyclist is 25 miles per hour.
How to calculate the value?Let the speed of a walker = x
Biker's speed = 1.5x
Their relative speed will be:
= 1.5x - x = 0.5x
Distance between them = 12.5 miles
Time taken = 1.5 hours.
It should be noted that distance will be:
= Speed × Time
12.5 = 1.5 × 0.5x
Divide through to get x
12.5 = 0.75x
x = 16.67 miles per hour.
Speed of cyclist = 16.67 × 1.5 = 25 miles per hour.

The most appropriate choice for complementary angle will be given by:
∠A = 27°
What are complementary angles?
Two angles are said to be complementary if the sum of the two angles is 90°
Here,
∠A = (2x + 5)°
∠B = (4x + 19)°
∠A and ∠B are complementary
(2x + 5) + (4x + 19) = 90

For the transformation of parent function f(x)=|x| to the g(x)=|x|+4, the transformation occurred is 4 units upward.
What is method to obtain a new function from parent function?Assume we have a parent function y=f (x). By simply bringing some constant c, one can generate a new function y=g(x) from parent function. The addition of such a constant alters the parent function's behavior, resulting in shifting, reflecting, extending, or reducing its graph. From that, we can claim that a new function evolves with different properties (such as domain as well as range) than the original function.The function transformation / translation principles are as follows: f (x) + b raises the function b units.
f (x) + b shifts a function b units upward.f (x) − b shifts a function b units downward.f (x + b) shifts a function b units to the left.f (x − b) shifts a function b units to the right.−f (x) reflects a function in x-axis (that is, upside-down).The given parent function is; f(x)=|x|
The transformed function is; g(x)=|x|+4
Thus, from the 1st rule of the transformation we can say that the function has shifted 4 units to upward.

Step-by-step explanation:
two people start from the same point. one walks east at 4 mi/h and the other walks northeast at 5 mi/h. how fast (in mi/h) is the distance between the people changing after 15 minutes? (round your answer to three decimal places.)
The change in distance between the two after 15 minutes is 3.566 mi/h
Velocity is defined as the rate of change in displacement (distance) with time. It's a vector quantity so it has both magnitude and direction. Velocity is given by the formula:
Velocity = distance / time
If one walks east at 4 mi/h and the other walks northeast at 5 mi/h, then after 15 minutes, their distance are:
distance = velocity * time
distance₁ = 4 mi/h (15 mins)(1 hour/60 mins)
distance₁ = 1 mile east
distance₁ = 5 mi/h (15 mins)(1 hour/60 mins)
distance₁ = 1.25 mile northeast
Using trigonometric function and Pythagorean theorem, we can determine the distance between the two people. (Refer to the attached picture.)
d² = (1.25 sin 45°)² + (1.25 cos 45° - 1)²
d² = 0.795
d = 0.891 mi
After 15 mins, the distance is 0.891 mi and the change in distance in mi/h is
(0.891 mi / 15 mins)(60 mins / hour) = 3.566 mi/h

Determine the bonus based upon the formula 2 weeks' salary plus 1 percent commission: annual salary: $48,000.00 yearly sales: $76,000.00
The bonus based upon the given formula is $2606.15 approximately
Given,
Annual salary = $48,000
Yearly sales = $76,000
Bonus is given according to the formula:
2 weeks salary + 1 percentage commission
Here,
Annual salary is given as $48,000
We have to find the weekly salary:
There is 52 weeks in a year.
So, salary for one week = Annual salary / number of weeks = 48000/52 = $923.077
Now, salary for two weeks = 923.077 × 2 = $1846.154
Rate of annual commission is 1%
The commission amount:
1% of yearly sales = 1% of 76000 = (1/100) × 76000 = $760
So,
The bonus amount = 2 weeks salary + 1 percentage commission
The bonus amount = 1846.154 + 760
The bonus amount = 2606.154
Therefore, the bonus given based upon the given formula is $2606.154

Mai wants to make an open-top box by cutting out the corners of a square piece of cardboard and folding up the sides. The cardboard is 10 centimeters by 10 centimeters. The volume () in cubic centimeters of the open-top box is a function of the side length in centimeters of the square cutouts.
Write an expression for ().
What is the volume of the box when =3?
The quantity of space inside a form is measured by its volume.
The volume as a function of side length(x) is: V(x) = 4x³ - 40x² + 100x
What is volume functions?
A three-dimensional space's volume can be calculated. It is frequently quantified numerically by different imperial units or SI-derived units. Volume and length have a mutually reliant relationship.
Given, length of the cardboard = 10 units
Width of the cardboard = 10 units
When side length(x) is removed from the cardboard, the dimension of the box becomes:
Length of the new cardboard = (10 - 2x) units
Width of the new cardboard = (10 - 2x) units
Height of the new cardboard = x units
Therefore, volume of the new cardboard box, V(x)
= Length*Width*Height
= x*(10 - 2x)*(10 - 2x) cubic units
= 100x² - 20x² - 20x² + 4x³
= 4x³ - 40x² + 100x

The values of y varies directly with x. If x=8, when y=16. What is the value of y when x=16???
I need help asap
Answer:
y = 32
Step-by-step explanation:
With this problem, we will use the direct variation form, y = kx.
k = proportionality constant.
Substitute the known inputs of x = 8 and y = 16 into the direct variation form:
y = kx turns into 16 = k(8)
Get k by itself by dividing 8 on both sides:
16/8 = k
2 = k
Now that we know the k value is 2, we input everything we know into the direct variation form if x were equal to 16
k = 2
x = 16
y = kx:
y = 2(16), making y equal to 32
