Answer: So when you double the radius, the area goes up by 4 times because 2 squared is 4. The area will always go up by the square of how much the radius goes up. By contrast, the circumference will only double -- from 12.56 to 25.12 because you do not square the radius (or diameter) -- you just multiply it by pi.

Answer:
19 h
Step-by-step explanation:
The angles of A and B are 45 degrees. This is true because the other angle is a right angle (90 degrees) and if you are making a triangle the degrees of the sides have to = 180 to be a complete triangle. The triangle is complete, so I took 180 – 90 = 90 ÷ 2 = 45.
The angle of C is 115 because it is a supplementary angle. A supplementary angle is an angle that has two angles with a sum of 180 degrees and 180 – 65 = 115

Answer:
(-5, -1)
Step-by-step explanation:
When two lines intersect, their x and y values are equal. So,
x = 3y - 2 must equal -7 - 2y = x
x = 3y - 2 = -7 - 2y = x
Let's look at the two middle equations and solve for y.
3y - 2 = -7 - 2y
Add 2y to both sides
5y - 2 = -7
Add 2 to both sides.
5y = -5
y = -1
Now, let's find x. You can use either equation for this step.
When y = -1, then 3y - 2 =
(3)(-1) - 2 = -3 - 2 = -5
So, x = -5, and y = -1
Thus, the answer is (-5, -1)
I hope this helps! Feel free to ask any questions!

whoever answers first and at least looks correct gets brainliest!!!
Answer:
2x - 1
Step-by-step explanation:
Simplify. Note that you cannot combine a term with a variable with a constant term. Divide 5 from both terms in the parenthesis:
1/5(10x - 5) = (10x - 5)/5
Divide 5 from both terms in the parenthesis:
10x/5 = 2x
-5/5 = -1
2x - 1 is your answer.

What is the partial fraction decomposition of
7x squared- 6x +9/
3x(4x squared +9)
9514 1404 393
Answer:
1/(3x) =(x -2)/(4x^2 +9)
Step-by-step explanation:
The denominator cannot be factored further, so the final form will be ...
A/(3x) + (Bx +C)/(4x^2 +9)
The value of this is ...
(A(4x^2 +9) +(3x)(Bx +C))/(3x(4x^2 +9))
= ((3B+4A)x^2 +3Cx +9A)/(3x(4x^2 +9))
Equating coefficients gives ...
3B+4A = 7
3C = -6 ⇒ C = -2
9A = 9 ⇒ A = 1
Using the found value of A, we find ...
3B +4 = 7 ⇒ B = 1
Then the decomposition is ...
[tex]\dfrac{7x^2-6x+9}{3x(4x^2+9)}=\boxed{\dfrac{1}{3x}+\dfrac{x-2}{4x^2+9}}[/tex]

Out of the 4,500 people who attend the rock concert, forty-six percent purchase a T-shirt. How many people buy T-shirts?
The number of people that bought T-shirt is 2070 people
What is percentage?A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, "%"
To find the percentage of those that bought the T-shirt
We find 45% of 4,500
45/100 * 4500

Use the quadratic equation y = –2x^2 + 4x +5 to complete the statements.
Answer:
Step-by-step explanation:
Given quadratic equation is,
y = -2x² + 4x + 5
y = -2(x² - 2x) + 5
y = -2(x² - 2x + 1 - 1) + 5
y = -2(x² - 2x + 1) + 2 + 5
y = -2(x - 1)² + 7
This equation is in the vertex form of the quadratic equation,
y = a(x - h)² + k
where, (h, k) is the vertex of the parabola.
Therefore, vertex of the given quadratic equation is (1, 7)
The equation can be rewritten as y = -2(x - 1)² + 7.
Therefore, the vertex of the graph of the function y = -2x² + 4x + 5 in the xy-coordinate plane is located at the point (1, 7).
In parallelogram ABCD, if m angle C= 110° and m angle D - 70°, what is the sum of the measures of LA and 28?
409
909
180°
360°
Answer:
180°
Step-by-step explanation:
ABCD is a parallelogram.
Measures of the opposite angles of a parallelogram are equal. Here [tex] \angle A, \:\: \angle C \: \: and\:\: \angle B, \:\: \angle D[/tex] are opposite angles.
[tex] \therefore m\angle A = m\angle C = 110\degree [/tex]
[tex] \& \:m\angle B = m\angle D = 70\degree [/tex]
[tex] m\angle A + m\angle B =110\degree + 70\degree [/tex]
[tex] m\angle A + m\angle B =180\degree [/tex]
B. Noah writes the equation 3 (x+7)=57 to represent the situation. DO YOU agree with him? Explain your answer.
Answer:
Yes , i agree with Noah that the equation would be 3(x + 7) = 57
Step-by-step explanation:
P.S - The exact question is -
To find - Noah writes the equation 3 (x+7)=57 to represent the situation.
DO YOU agree with him? Explain your answer.
Proof -
Yes , i agree with Noah
Because in the figure we can see that there is x written 3 times and 7 written 3 time and whole the values is equal to 57 .
Because 57 is divided into x 7 x 7 x 7
∴ we can write it as
3 times x + 3 times 7 = 57
⇒3(x) + 3(7) = 57
⇒3(x+7) = 57
Ans Noah give the same equation 3 (x+7)=57
So, I agree with Noah.
