PLEASE HELP ME ANSWER THIS QUESTION.... 20 POINTS
Answer is Step-by-step explanation:
The two shorter sides are the legs of the right triangles. Both are given for triangle B. Use Pythagorean Theorem or pythagorean triples(shortcut/special case) to show the missing side of Triangle A is also 5.
leg^2+ leg^2 = hyp^2
x^2 + 12^2 = 13^2
x^2 + 144 = 169
subtract 144.
x^2 = 25
square root both sides.
x = 5
The missing side of Triangle A is 5, same as triangle B.
Just to really show it. Calc the missing side of triangle B
5^2 + 12^2 = h^2
25 + 144 = h^2
169 = h^2
squareroot both sides.
13 = h
The hypotenuse of both triangles is 13. All the measures of all the corresponding sides are the same for these two triangles.

Which is a factor of x2 8x – 48? (x – 6) (x 4) (x – 16) (x 12)
The factor of the polynomial is be (x+12)
We have given equation is
[tex]x^2+8x-48[/tex]
The middle number is 8 and the last number is -48.
Factoring means we want something like
[tex](x-a)and (x+b)[/tex]
we have to find the value of a and b
Which are two numbers whose addition is 8 and multiplication is -48?
The numbers are (12) and -4
addition=12+(-4)=12-4=8
12(-4)=-48
Therefore we have,
[tex]x^2+8x-48\\x^2+12x-4x-48\\\\x(x+12)-4(x+12)\\(x-4)(x+12)[/tex]
Therefore the given equation has two factor that are (x-4) and (x+12)
Since (x-4) is not in option therefore the answer would be (x+12)

Answer:
C. x = {1/5, 1}
Step-by-step explanation:
2|6x - 2| = 8x
2(6x - 2) = 8x and 2(6x - 2) = -8x
2(6x - 2) = 8x
12x - 4 = 8x
4x = 4
x = 1
2(6x - 2) = -8x
12x - 4 = -8x

Using figure at the right, find:
1. BS
2. RS
3. ST
Answer:
1. BS = 4
2. RS = 2√5
3. ST = 4√5
Step-by-step explanation:
Use the right triangle altitude theorem.
Then use the Pythagorean Theorem.
1.
BT/BS = BS/BR
8/BS = BS/2
(BS)² = 16
BS = 4
2.
2² + 4² = (RS)²
RS = √(20)
RS = 2√5
3.
4² + 8² = (ST)²
ST = √(80)
ST = 4√5

AB, CD, and EF intersect at O. If CD is perpendicular to EF and m
Answer:
m(∠AOF) = 148°
Step-by-step explanation:
From the figure attached,
CD intersects line EF at a point O.
Line CD is perpendicular to the line EF.
m(∠AOE) = 32°
m(∠COE) = 90°
Since m(∠COE) = m(∠AOE) + m(∠AOC) = 90°
32° + m(∠AOC) = 90°
m(∠AOC) = 90° - 32° = 58°
m(∠AOF) = m(∠AOC) + m(∠COF)
= 58° + 90°
= 148°
Therefore, m(∠AOF) = 148° will be the answer.

Match graph with choices below!
Answer:
○ [tex]\displaystyle None\:of\:these[/tex]
Step-by-step explanation:
[tex]\displaystyle \boxed{y = 2cos\:(2x - \frac{\pi}{2})} \\ y = Acos(Bx - C) + D \\ \\ Vertical\:Shift \hookrightarrow D \\ Horisontal\:[Phase]\:Shift \hookrightarrow \frac{C}{B} \\ Wavelength\:[Period] \hookrightarrow \frac{2}{B}\pi \\ Amplitude \hookrightarrow |A| \\ \\ Vertical\:Shift \hookrightarrow 0 \\ Horisontal\:[Phase]\:Shift \hookrightarrow \frac{C}{B} \hookrightarrow \boxed{\frac{\pi}{4}} \hookrightarrow \frac{\frac{\pi}{2}}{2} \\ Wavelength\:[Period] \hookrightarrow \frac{2}{B}\pi \hookrightarrow \boxed{\pi} \hookrightarrow \frac{2}{2}\pi \\ Amplitude \hookrightarrow 2[/tex]
OR
[tex]\displaystyle \boxed{y = 2sin\:2x} \\ y = Asin(Bx - C) + D \\ \\ Vertical\:Shift \hookrightarrow D \\ Horisontal\:[Phase]\:Shift \hookrightarrow \frac{C}{B} \\ Wavelength\:[Period] \hookrightarrow \frac{2}{B}\pi \\ Amplitude \hookrightarrow |A| \\ \\ Vertical\:Shift \hookrightarrow 0 \\ Horisontal\:[Phase]\:Shift \hookrightarrow 0 \\ Wavelength\:[Period] \hookrightarrow \frac{2}{B}\pi \hookrightarrow \boxed{\pi} \hookrightarrow \frac{2}{2}\pi \\ Amplitude \hookrightarrow 2[/tex]
You will need the above information to help you interpret the graph. First off, keep in mind that although this looks EXACTLY like the sine graph, if you plan on writing your equation as a function of cosine, then there WILL be a horisontal shift, meaning that a C-term will be involved. As you can see, the photograph on the right displays the trigonometric graph of [tex]\displaystyle y = 2cos\:2x,[/tex]in which you need to replase "sine" with "cosine", then figure out the appropriate C-term that will make the graph horisontally shift and map onto the sine graph [photograph on the left], accourding to the horisontal shift formula above. Also keep in mind that the −C gives you the OPPOCITE TERMS OF WHAT THEY REALLY ARE, so you must be careful with your calculations. So, between the two photographs, we can tell that the cosine graph [photograph on the right] is shifted [tex]\displaystyle \frac{\pi}{4}\:unit[/tex]to the left, which means that in order to match the sine graph [photograph on the left], we need to shift the graph FORWARD [tex]\displaystyle \frac{\pi}{4}\:unit,[/tex]which means the C-term will be positive, and by perfourming your calculations, you will arrive at [tex]\displaystyle \boxed{\frac{\pi}{4}} = \frac{\frac{\pi}{2}}{2}.[/tex]So, the cosine graph of the sine graph, accourding to the horisontal shift, is [tex]\displaystyle y = 2cos\:(2x - \frac{\pi}{2}).[/tex]Now, with all that being said, in this case, sinse you ONLY have a graph to wourk with, you MUST figure the period out by using wavelengths. So, looking at where the graph hits [tex]\displaystyle [-2\frac{1}{4}\pi, -2],[/tex]from there to [tex]\displaystyle [-1\frac{1}{4}\pi, -2],[/tex]they are obviously [tex]\displaystyle \pi\:units[/tex]apart, telling you that the period of the graph is [tex]\displaystyle \pi.[/tex]Now, the amplitude is obvious to figure out because it is the A-term, but of cource, if you want to be certain it is the amplitude, look at the graph to see how low and high each crest extends beyond the midline. The midline is the centre of your graph, also known as the vertical shift, which in this case the centre is at [tex]\displaystyle y = 0,[/tex]in which each crest is extended two units beyond the midline, hence, your amplitude. So, no matter how far the graph shifts vertically, the midline will ALWAYS follow.
I am delighted to assist you at any time.

Dr. David Smith lived 1/13 of his life as a child. He spent 4/39 of his life preparing for an outstanding
medical career. For 1/ 2 of his life, he was a successful surgeon in a famous children's hospital. Since his
retirement, he has lived 13 years on a comfortable pension. How old is he? (unrealistic answer))
Answer:
40 14/25 years
Step-by-step explanation:
Well, this certainly is fun.
First, to find the fraction of the doctor's life which 13 years represents, subtract the fractions from 1 (and in this case l stands for lifetime):
[tex]13 = (1 - (\frac{1}{13} + \frac{4}{39} + \frac{1}{2}))(l)[/tex]
[tex]13 = (\frac{25}{78})(l)[/tex]
So, multiply this equation by the reciprocal of 25/78 to isolate one of l:
[tex]13(\frac{78}{25}) = l[/tex]
[tex]l = 40\frac{14}{25}[/tex] years

A store owner paid $15 for a dvd. he marked up the price of the dvd by 30% to determine his selling price. what is his selling price to the nearest hundredth (do not include a dollar sign in your answer)?
The selling price of the DVD that has a cost of 15 dollars is 19 dollars and 50 cents.
What is the percentage?The amount of something is expressed as if it is a part of the total which is a hundred. The ratio can be expressed as a fraction of 100. The word percent means per 100. It is represented by the symbol ‘%’.
A store owner paid $15 for a DVD.
He marked up the price of the DVD by 30%.
The cost price is $15.
Then the selling price will be given as
Selling price = 15 × 1.3
Selling price = $19.50
The selling price is 19 dollars and 50 cents.
