Step-by-step explanation:
The length of c using the Pythagorean theorem is 50 units.
What is Trigonometry?Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.
The given triangle is ABC which is right angle triangle
AB=c
BC=14 and AC=48
We have to find the value of c
By Pythagoras theorem, in a right-angled triangle, the square of the hypotenuse side is equal to the sum of squares of the other two sides
AB²=AC²+BC²
c²=48²+14²
c²=2304+196
c²=2500
Take square root on both sides
c=√2500
c=50
Hence, the length of c using the Pythagorean theorem is 50 units.

***3/2x + 1/2x + x = 180 degrees***
For the other way you can switch around the positions of the angles in the equation as long as the = stays 180 so like
X + 3/2x + 1/2x = 180
180 + x + 1/2x + 3/2x
Or maybe change the 3/2x to 1 1/2x
Which value of x makes this equation true? 35 + 42 = 12 + x
Answers
Answer:

If –y + 2x^2 – x = -5y^3 then find dy / dx in terms of x and y.
Answers
Answer:
dy/dx = [tex]\frac{4x-1}{1-15y^{2} }[/tex]
Step-by-step explanation:
-y + 2x²- x = -5y³
2x² - x = y - 5y³
4x - 1 = dy/dx - 15y².dy/dx
dy/dx(1 - 15y²) = 4x - 1

Which of the following is equivalent to -(7/4) ?
A. 7/-4
B. -7/-4
C. 4/-7
D. 7/4
Answers
Answer:
A
Step-by-step explanation:
-(7/4) equals -7/4 or negative seven forths. Its doesn't matter where the negative sign is as long there's only 1 of them and that its still 7/4.
So through process of elimination, we take out B because theres 2 negative, which make a positive, our answer is negative
C is wrong because its 4/7, not 7/4
D is wrong because it's positive, leaving us with A

Absolute value equations are equations where the variable is within an absolute value operator, like |x-5|=9. The challenge is that the absolute value of a number depends on the number's sign: if it's positive, it's equal to the number: |9|=9. If the number is negative, then the absolute value is its opposite: |-9|=9.

Elena is playing a dice game with her father. She will win if she DOES NOT roll a 1, 3, or 6. Find the probability that Elana wins on her next roll.
Answers
Answer:
The probability that she was on her next roll is 1/2
Step-by-step explanation:
If she does not roll 1,3 or 6, she wins
So if she rolls 2,4 and 6 , she wins
The probability of rolling each is 1/6 each
So the probability of rolling any of the three will be:
1/6 + 1/6 + 1/6 = 3/6 = 1/2
To change Celsius temperatures to Fahrenheit temperatures, you can use the formula F = 95C + 32. Which answer is the best first step to solve the equation for C?
Answers
Answer: I think that the guy above is right just subtract 32.
An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
The first step in solving the equation for C is
Subtract 32 on both sides.
F - 32 = 95C + 32 - 32
F - 32 = 95C

We have,
To change Celsius temperatures to Fahrenheit temperatures, you can use the formula F = 95C + 32.
Solve for C.
F = 95C + 32
Step 1:
Subtract 32 on both sides.
F - 32 = 95C + 32 - 32
F - 32 = 95C
Divide both sides by 95.
(F - 32)/95 = C
C = (F - 32) / 95
Thus,
The first step in solving the equation for C is
Subtract 32 on both sides.
F - 32 = 95C + 32 - 32
F - 32 = 95C

x1 would be 9, x2 would be -3, y1 would be 2, y2 would be -2. When plugged in, you should get 6/2, and 0/2 for y. When simplified, x would be 3 and y would be 0. This means that the midpoint of the line segment is (3,0)
