Isaiah is jogging near his college. He runs south along Capitol Street for about 0. 75 miles and east along H Street for about 1. 2 miles. He then turns left and runs along Florida Avenue until he reaches his starting point. How long is his total run to the nearest hundredth of a mile? A triangle. The sides are Capitol Street, H Street, and they hypotenuse is Florida Avenue. 2. 89 miles 3. 37 miles 3. 67 miles 3. 92 miles.
Answer:
His total run is approximately 3.37 miles.
Step-by-step explanation:
Let F represents his starting point, C represents his position from where he went to east direction and H represents his position from where he went to left towards Florida Avenue.
Thus, according to the question,
FC = 0.75 miles,
CH = 1.2 miles,
By making the diagram,
∠FCH = 90°,
By Pythagoras theorem:
Hence, the total distance he covered = FC + CH + FH
= 0.75 + 1.2 + √2.0025
= 3.36509716981
≈ 3.37 miles.

Is it possible to write a polynomial of degree 3 with zeros at 5, 3 and 8i? Explain your reasoning.
Answer:
No
Step-by-step explanation:
Because if 8i is a zero then -8i is also a zero. That means you now have four zeros, so the function is at least a fourth degree (quartic) function.
It is not possible to write a polynomial of degree 3 with zeros 5, 3 and 8i.
What is degree of polynomial?
A polynomial’s degree is the highest or the greatest power of a variable in a polynomial equation.
The degree of a polynomial is equal to the real zeros of the polynomial. Real zeros of the polynomial are 5 and 3 only. 8i is a complex number. Thus degree of the polynomial is 2.

Which statement verifies that f(x) and g(x) are inverses of each other?.
Answer:
f(g(x)) = g(f(x)) = x
which is the same as
(f ° g)(x) = (g ° f)(x) = x
Step-by-step explanation:
If the functions are inverses of each other, they will yield just x when they are composed together. Being inverses is like one function "UNDOES" the other (this is not a technical term).

A candle burns down at the rate of 0.5 inches per hour. The original height of the candle was 8 inches.
Part A: Write a list of 6 ordered pairs to show the height of the candle in inches (y) as a function of time in hours (x) from the first hour after it started burning. For example, the point (0, 8) would represent a height of 8 inches after 0 hours. Explain how you obtained the ordered pairs.
Part B: Is this relation a function? Justify your answer using the list of ordered pairs you created in Part A.
Part C: If the rate at which the candle burned was 0.4 inches per hour instead of 0.5 inches per hour, would the relation be a function? Explain your answer using input and output values.
Will mark Brainlist!!!
Answer: PART A.
y= remaining height of candle
x= rate the candle burns down in inches per hour
8= original height of candle
the function would be y=8- 0.5x because the candle starts at a height of 8 feet and loses half an inch per hour.
You can use this function to create ordered pairs by putting in number at x which indicates the time:
x=1
y=8- (.5×1)= 7.5
(1, 7.5)
you can then do this for other numbers and get:
(2, 7.0) (3, 6.5) (4, 6.0) (5, 5.5) (6, 5.0)
PART B.
This equation is a function because all of the x-values had different y-values as seen in the coordinates (1, 7.5) (2, 7.0) (3, 6.5) (4, 6.0) (5, 5.5) (6, 5.0)
PART C.
If the rate was 0.4 inches an hour, it would still be a function because the rate is the only thing that changed making the new function y= 8- 0.4x.This equation would make coordinates of (0,8) (1, 7.6) (2, 7.2) (3, 6.8) and so on with each x value creating a different y value.

The property of equality applied to solve the equation is division property of Equality.
What is the property of equality?Property of equality says that by performing any mathematical operation, of both sides of an expression does not change the original value of the equation.
The equation given in the problem is,
[tex]0.36 x = -1. 8[/tex]
This equation is solved further by dividing both side of the expression with decimal number 0.36 as,
[tex]\dfrac{0.36}{0.36}x = -\dfrac{1. 8}{0.36}\\x=-5[/tex]

Elliot makes and sells key chains. His profit depends on what price he charges for a key chain. He writes the expression (1 - 10) (60 - 3x) to represent his profit based on the price per key chain, I. Profit (S) 40+ 20+ Use the drop-down menus to complete the statements about Elliot's profit.
Using the vertex of the quadratic function, it is found that his maximum profit is of $75 when he charges $15 for a key-chain.
What is the vertex of a quadratic equation?A quadratic equation is modeled by:
[tex]y = ax^2 + bx + c[/tex]
The vertex is given by:
[tex](x_v, y_v)[/tex]
In which:
[tex]x_v = -\frac{b}{2a}[/tex]
[tex]y_v = -\frac{b^2 - 4ac}{4a}[/tex]
Considering the coefficient a, we have that:
If a < 0, the vertex is a maximum point.If a > 0, the vertex is a minimum point.In this problem, the function is:
[tex]f(x) = (x - 10)(60 - 3x)[/tex]
In standard format, it is given by:
[tex]f(x) = -3x^2 + 90x - 600[/tex]
Which means that it's coefficients are a = -3, b = 90, c = -600.
Hence:
[tex]x_v = -\frac{90}{2(-3)} = 15[/tex]
[tex]y_v = -\frac{90^2 - 4(-3)(-600)}{4(-3)} = 75[/tex]
Hence, his maximum profit is of $75 when he charges $15 for a key-chain.
