Rewrite the function by completing the square. f(x)=x^2+16x-46
Answer:
[tex]f(x)=(x+8)^{2}-110[/tex]
Step-by-step explanation:
Completing the square is a multi-step process that involved rewriting an equation such that it has a factored term, a coefficient, and a constant. First, group the equation, then add a term such that the grouped part of the equation can be simplified, then balance the equation, finally simplify and factor the equation.
[tex]f(x)=x^{2} +16x - 46\\[/tex]
Group;
[tex]f(x)=(x^{2}+16)-46[/tex]
Add in a term that makes the grouped part of the equation a perfect square, this can be done by dividing the linear term by 2, then balancing the equation;
[tex]f(x)=(x^{2}+16x+64)-46-64[/tex]
Simplify, factor;
[tex]f(x)=(x+8)^{2} - 110[/tex]

A ramp has an angle of inclination of 20 degrees. it has a vertical height of 1.8 m. what is the length, l metres, of the ramp?
Answer:
x = 5.26 m
Step-by-step explanation:
Given that,
The angle of inclination = 20°
The vertical height of the ramp, h = 1.8 m
We need to find the length of the ramp. Let it is x.
We can find it using trigonometry. So,
[tex]\sin\theta=\dfrac{P}{H}[/tex]
We have,
P = 1.8 m, H = x
[tex]\sin20=\dfrac{1.8}{x}\\\\x=\dfrac{1.8}{\sin20}\\\\x=5.26\ m[/tex]
So, the length of the ramp is 5.26 m.

This graph shows the amount of charge left on my computer, c, after I have been awake for h hours.
How many hours will I have been awake when my computer has no charge left?
Use the sketch tool if it helps you with your thinking.
Based on the graph given above, the hours you will have to be awake when your computer has 0% charge is: 4.5 hours.
How to Interpret a Graph?Analyzing the graph given in the image above, where c represents the amount of charge you have left on your computer, and h represents the number of hours after you have been awake, the graph shows the following:
The unit rate = -30, which means the charge on your computer dropped at 30% per hour.The initial charge on your computer was the y-intercept of the graph, which is 90%.Your computer will have 0% after 4.5 hours that you have been awake (this is the x-intercept of the graph).Therefore, the number of hours you will have been awake for your computer to have no charge left is: 4.5 hours.

What is the area of a rectangle that is 1/2 feet long and 2/3 feet wide?
Hint: Put the fraction in form
A:3/5
B;1/3
C:2/6
Answer:
B
Step-by-step explanation:
Area of a rectangle is length multiplied by width. So 2/3 times 1/2 which equals 1/3 or .33333 repeated
Answer:
B. 1/3.
Step-by-step explanation:
The area of a rectangle is represented by the following equation:
Area = width x height
In this case it would look like this:
[tex]Area = \frac{1}{2} * \frac{2}{3}[/tex]
Now, we solve:
[tex]Area = \frac{2}{6} \\Area = \frac{1}{3}[/tex]
Therefore, the correct answer is B. 1/3.

The graph of a proportional relationship passes through the point (6, 21). What is the equation for the relationship?
Answer:
The equation for the relationship is [tex]y = \frac{7}{2}\cdot x[/tex].
Step-by-step explanation:
Given that point [tex](x,y) = (6, 21)[/tex] is part of a direct relationship. That is:
[tex]y \propto x[/tex]
[tex]y = k\cdot x[/tex] (1)
Where [tex]k[/tex] is the proportionality constant.
If we know that [tex]x = 6[/tex] and [tex]y = 21[/tex], then the proportionality constant is:
[tex]k = \frac{y}{x}[/tex]
[tex]k = \frac{21}{6}[/tex]
[tex]k = \frac{7}{2}[/tex]
Lastly, the equation for the relationship is [tex]y = \frac{7}{2}\cdot x[/tex].
