Answer:
14
Step-by-step explanation:
The product of two consecutive odd numbers equals 55 plus ten times the even number which is between them. Find the even number.
Let the two odd consecutive integer be x and x+2
Let the even number between then be x+1
If the product of two consecutive odd numbers equals 55 plus ten times the even number, then;
(x)(x+2) = 55 + 10(x+1)
Expand
x² + 2x = 55 + 10x + 10
x² -8x -65 = 0
x² - 13x+5x - 65 = 0
x(x-13)+5(x- 13) = 0
(x-13) (x+5) = 0
x = 13 and -5
Since the even number is x + 1
Even number = 13 + 1 = 14
Factor [tex]2x^2+13x-7[/tex]
the difference between area and surface area.
Answer:
Area- Measurment of the size in the flat surface of a plane (Two Dimensional)
Surface Area- Measurment of the exposed surface of a soilid shape (Three Dimensional)

How to find the derivative of the below question?
Given:
[tex]y=\dfrac{x}{\sqrt{x-1}}[/tex]
To find:
The derivative of the given problem.
Solution:
Chain rule : [tex]\dfrac{d}{dx}f(g(x))=f'(g(x))\cdot g'(x)[/tex]
Quotient rule : [tex]\dfrac{d}{dx}\left(\dfrac{f(x)}{g(x)}\right)=\dfrac{g(x)f'(x)-f(x)g'(x)}{[g(x)]^2}[/tex]
We have,
[tex]y=\dfrac{x}{\sqrt{x-1}}[/tex]
Differentiating with respect to x using chain rule and quotient rule, we get
[tex]\dfrac{dy}{dx}=\dfrac{\sqrt{x-1}\dfrac{d}{dx}(x)-x\dfrac{d}{dx}(\sqrt{x-1})}{(\sqrt{x-1})^2}[/tex]
[tex]\dfrac{dy}{dx}=\dfrac{\sqrt{x-1}(1)-x\dfrac{1}{2\sqrt{x-1}}\dfrac{d}{dx}(x-1)}{(x-1)}[/tex]
[tex]\dfrac{dy}{dx}=\dfrac{\sqrt{x-1}-\dfrac{x}{2\sqrt{x-1}}(1-0)}{x-1}[/tex]
[tex]\dfrac{dy}{dx}=\dfrac{\sqrt{x-1}-\dfrac{x}{2\sqrt{x-1}}}{x-1}[/tex]
[tex]\dfrac{dy}{dx}=\dfrac{\dfrac{2x-2-x}{2(x-1)^{\frac{1}{2}}}}{(x-1)}[/tex]
[tex]\dfrac{dy}{dx}=\dfrac{x-2}{2(x-1)^{\frac{3}{2}}}[/tex]
Therefore, the required derivative is [tex]\dfrac{dy}{dx}=\dfrac{x-2}{2(x-1)^{\frac{3}{2}}}[/tex].
A teacher wants to investigate whether listening to music while taking a math test increases scores. He instructs half
of his 36 students to listen to music while taking a test and the other half to not listen to music during the test. To
determine who listens and who does not, the teacher identifies the two students who scored highest on the last test
and randomly instructs one to listen to music and one to not. The teacher does the same for the next two highest-
scoring students and continues in this manner until each student has their instructions. Which of the following best
describes this plan?
O This is a cluster sample.
O This is an observational study.
O This is a stratified random sample.
O This is an experiment with blocking.
O This is a completely randomized experiment.

Find the slope of the line that passes through (2, 12) and (9, 3).
Simplify your answer and write
as a proper fraction, improper fraction, or integer.
Answer:
The slope of line is [tex]-\frac{9}{7}[/tex].
Step-by-step explanation:
Given points are;
(2, 12) and (9, 3)
Here,
x1 = 2 and y1 = 12
x2 = 9 and y2 = 3
Slope of a line is given by the following formula;
[tex]m =\frac{y_2-y_1}{x_2-x_1}\\\\m = \frac{3-12}{9-2}\\\\m=\frac{-9}{7}[/tex]
Therefore,
The slope of line is [tex]-\frac{9}{7}[/tex].

For her birthday, Bonnie's parents gave her $5,425.00 which they put into a savings account that earns 15% interest compounded annually. When Bonnie started college, she withdrew the entire balance of $16,642.00 and used it to pay for tuition. How long was the money in the account?
Answer:
15% of $5425.00 = 5425 x- 15% = 813.75
$16,642.00 ÷ 813.75 = 20.3 = 20
So approx. 20 years

8(3x-2)=2(8)+16 explanation how the order of operations is used. How the equation is kept balanced.
Answer:
See explanation
Step-by-step explanation:
Given;
8(3x-2)=2(8)+16
We clear the brackets
24x - 16 = 16 + 16
24x - 16 = 32
We add 16 to both sides
24x - 16 + 16= 32 + 16
24x = 48
We divide both sides by 24
24x/24 = 48/24
x =2

In triangle XYZ, let angle Y be a right angle, mZ = 54°, and YZ = 361. Find the area of the
triangle. Round to the nearest whole number.
Answer:
89,709
Step-by-step explanation:
∡Z= 54°
tan 54 = XY / 361
XY = 361 · tan 54°
XY = 497
A = 1/2 (361) (497)

Answer:
The function is constant from x = -2 to x = 1.
Step-by-step explanation:
To find the range of where the function is constant, just look at the graph where the line is horizontal. It is horizontal from the x-values of x=-2 to x=1, and this is the range of when the function is constant.
