Answer: See attached
Step-by-step explanation:
Given:
y = -x² + 6x - 5
Since this is a quadratic function, we will have a parabola.
Because our x² value is negative, this parabola will be a "frowny face" instead of a "smiley face" like the parent function.
The - 5 means we shift the function 5 units to the right from the parent function.
See attached for our graph.
What parent function am I mentioning?
The parent function of y = -x² + 6x - 5 is y = x²

What is the radius of a circle with a
circumference of 26.69 centimeters?
Step-by-step explanation:
[tex]c = 2\pi \: r \\ 26.69 = 2\pi \: r \\ r = 26.69 \div 2(3.14) \\ r = 4.25 \: cm[/tex]
Answer:
4.25 cm
Step-by-step explanation:
Circumference of a circle = 2πr (where r is the radius)
[tex]\implies 26.69=2 \pi r[/tex]
[tex]\implies r=\dfrac{26.69}{2\pi }[/tex]
[tex]\implies r=4.247845431...[/tex]
[tex]\implies r=4.25\:\textsf{cm (nearest hundredth})[/tex]
Using [tex]\pi=3.14[/tex]:
[tex]\implies r=\dfrac{26.69}{2 \cdot 3.14}=4.25\: \sf cm[/tex]

The width w of a credit card is 3 centimeters shorter than the length 1. The area is 46.75 square centimeters. Find the
perimeter.
Answer:
28 cm
Step-by-step explanation:
Area = 46.75 = l * (l-3) shows l = 8.5 cm (using Quadratic Formula)
then w = 5.5
perimeter = 2 * ( 8.5+5.5) = 28 cm
The perimeter of the given card is 28 cm.
What is perimeter?Perimeter of an object is given by adding the side lengths of the object.
Given that, the width w of a credit card is 3 cm shorter than the length. The area is 46.75 cm².
We need to find the perimeter of the credit card,
Let the length be l,
Therefore,
Area = length x width
46.75 = l x (l-3)
46.75 = l² - 3l
l² - 3l - 46.75 = 0
Finding l, we get,
l = 8.5, l = -5.5
Since, length cannot be negative so, l = 8.5 cm
So, width = 8.5 - 3 = 5.5 cm
Perimeter = 2(l+w)
= 2(5.5+8.5) = 28 cm
Hence, the perimeter of the given card is 28 cm.

The area of a rectangle is 45 square inches. One dimension is 5 inches. What is the perimeter
Answer:
28 inches
Step-by-step explanation:
To begin, the area of a rectangle is base · height. Since we are given one of the sides already, you can make an equation to solve for the other value.
5 · x = 45
5x = 45
x = 9
A rectangle has two pairs of parallel sides, or in easier terms, two sets of sides that are the same. So, the perimeter is going to be two lengths plus two widths.
2 · 5 + 9 · 2 = 10 + 14 = 28

The logarithmic function is the inverse of the exponential function
The logarithmic equivalent of the exponential function is log(12) = [tex]\frac 43[/tex]log(x) + log(y) + 2log(z)
How to convert the function?The exponential function is given as:
12^3=x^4 y^3 z^6
Take the logarithm of both sides
log(12^3) =log(x^4 y^3 z^6)
Apply the product rule of logarithm
log(12^3) =log(x^4) + log(y^3) + log(z^6)
Apply the power rule of logarithm
3log(12) = 4log(x) + 3log(y) + 6log(z)
Divide through by 3
log(12) = [tex]\frac 43[/tex]log(x) + log(y) + 2log(z)
Hence, the logarithmic equivalent of the exponential function is log(12) = [tex]\frac 43[/tex]log(x) + log(y) + 2log(z)

Part 1: Determine the limits of a function given a graph
The value of limits and function values for a, b, c, d, e, f, g, h, i, and j are 3, -1, does not exist, 3, 1, 2, does not exist, 2 +∞, and -∞ and doesn't follow continuity conditions and its jump continuity.
What is the limit?A limit is a value at which a function approaches the output for the given values in mathematics. Limits are used to determine integrals, derivatives, and continuity in calculus and mathematics.
We have a graph of a function:
For [tex]\lim_{x \to -1^{-1}} f(x)[/tex]
As we can see x approaches -1 and it is a left-hand limit.
[tex]\lim_{x \to -1^{-1}} f(x) = 3[/tex]
For [tex]\lim_{x \to -1^{+1}} f(x)[/tex]
The x approaches the +1 and it is the right-hand limit.
[tex]\lim_{x \to -1^{+1}} f(x) = -1[/tex]
For [tex]\lim_{x \to -1} f(x)[/tex]
Since the left hand and right-hand limits are not the same,
[tex]\lim_{x \to -1^{+1}} f(x)[/tex] = does not exist
From the graph:
f(-1) = 3
Similarly, we can find further values of the limits and functions value:
[tex]\lim_{x \to 2^{-1}} f(x) = 1[/tex]
[tex]\lim_{x \to 2^{+1}} f(x) = 2[/tex]
For [tex]\lim_{x \to 2^{}} f(x)[/tex]
Since the left hand and right-hand limits are not the same,
[tex]\lim_{x \to 2^{}} f(x)[/tex] = does not exist
f(2) = 2
[tex]\lim_{x \to -\infty} f(x) = +\infty[/tex]
[tex]\lim_{x \to +\infty} f(x) = -\infty[/tex]
There are three conditions a graph must follow:
1) function value defined at any given point.
2) left-hand limit and right-hand limit must be equal
3) function value at the point and limit value at the same point must be the same.
In the given function the graph doesn't follow these conditions and its jump continuity.
Thus, the value of limits and function values for a, b, c, d, e, f, g, h, i, and j are 3, -1, does not exist, 3, 1, 2, does not exist, 2 +∞, and -∞ and doesn't follow continuity conditions and its jump continuity.

When the shadow of a flagpole is 36 m long, a 1.8-m fencepost casts a shadow that is 3 m long. How tall is the flagpole?
Answer:
21.6 m long
Step-by-step explanation:
To do this, we find the scale factor of the fencepost and the shadow.
3/1.8 = 1.66666667
So, we know that when we take the original length and multiply it, we get the new one, so:
1.666666667 * x = 36
x being the original length. Now, we divide both sides by 1.66666667 to get x alone and find the original length.
x = 21.6
To double check, we can take the scale factor and multiply it by the original to get the shadow.
21.6 * 1.666666667 = 36
It is correct
