Answer:
The mean is 6. When you add all the numbers you get 66 and then youre suppose to divide 66 by 10 in order to get the mean which is 6.
Step-by-step explanation:
4 + 5 + 5 + 6 + 6 + 7 + 8 + 8 + 8 + 9 = 66
66 ÷ 10 = 6
∠A and \angle B∠B are complementary angles. If m\angle A=(x+10)^{\circ}∠A=(x+10)
∘
and m\angle B=(3x+28)^{\circ}∠B=(3x+28)
∘
, then find the measure of \angle B∠B.
Answer:
67
Step-by-step explanation:
Complementary angles add to 90 degrees
<A + <B = 90
x+10 + 3x+28 = 90
Combine like terms
4x+38 =90
Subtract 38 from each side
4x+38-38 = 90-38
4x = 52
Divide by 4
4x/4 = 52/4
x = 13
We want to find <B
<B = 3x+28
= 3(13) +28
= 39+28

Y={2x-1)(x+4)(2x-3)(x-1)
Answer:
Y =4x^4 + 4x^3 − 37x^2 + 41x −12
Step-by-step explanation:
Y = (2x - 1 ) (x + 4) (2x - 3) (x - 1)
Using commutative property we can re-arrange RHS,
Y= (2x - 1) (2x - 3) (x + 4) (x - 1)
Using the property
[(x+a) (x+b) = x^2 + (a+b)*x +ab],
Y =
[(2x)^2 + (-1 - 3)*2x + (-1 )*(-3)] [x^2 + (4 - 1)*x + 4*(-1)]
From here onwards I would recommend u to do the calculation by your own bc I might have made mistakes
in the steps but I got right but still just check yourself if u copy all the steps as it is
Y = (4x^2 -8x + 3) (x^2 + 3x -4)
Y = 4x^4 + 12x^3 - 16x^2 -8x^3 -24x^2 + 32x + 3x^2 + 9x - 12
Y = 4x^4 + 4x^3 -37x^2 + 41x - 12

Find an equation for the line that passes through the points (-1,-4) and (5,-2)
Linear equations are typically organized in slope-intercept form:
[tex]y=mx+b[/tex]
m = the slope of the lineb = the y-intercept (the value of y when the line crosses the y-axis)To determine a linear equation in slope-intercept form:
Find the slopePlug the slope into y=mx+bFind the y-interceptPlug the y-intercept into y=mx+bSolving the QuestionWe're given:
The line passes through the points (-1,-4) and (5,-2)First, find the slope of the line (m):
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex] where two points that fall on the line are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]
⇒ Plug in the given points (-1,-4) and (5,-2):
[tex]m=\dfrac{-2-(-4)}{5-(-1)}\\\\m=\dfrac{-2+4}{5+1}\\\\m=\dfrac{2}{6}\\\\m=\dfrac{1}{3}[/tex]
⇒ Therefore, the slope of the line is [tex]\dfrac{1}{3}[/tex]. Plug this into y=mx+b:
[tex]y=\dfrac{1}{3}x+b[/tex]
Now, determine the y-intercept (b):
[tex]y=\dfrac{1}{3}x+b[/tex]
⇒ Plug in one of the points and solve for b:
[tex]-4=\dfrac{1}{3}(-1)+b\\\\-4=-\dfrac{1}{3}+b\\\\-4+\dfrac{1}{3}=b\\\\b=-\dfrac{11}{3}[/tex]
⇒ Therefore, the y-intercept is [tex]-\dfrac{11}{3}[/tex]. Plug this back into our original equation:
[tex]y=\dfrac{1}{3}x-\dfrac{11}{3}[/tex]
Answer[tex]y=\dfrac{1}{3}x-\dfrac{11}{3}[/tex]

given f (x)=x-4/x^2+13x+36 which of the following is true
The function [tex]f(x) =\frac{x - 4}{x^2 + 13x + 36}[/tex] is a rational function
The simplified expression of the function [tex]f(x) =\frac{x - 4}{x^2 + 13x + 36}[/tex] is [tex]f(x) =\frac{x - 4}{(x + 9)(x + 4)}[/tex]
How to simplify the function?The function expression is given as:
f(x) =x - 4/x^2 + 13x + 36
Rewrite properly as:
[tex]f(x) =\frac{x - 4}{x^2 + 13x + 36}[/tex]
Expand the denominator
[tex]f(x) =\frac{x - 4}{x^2 + 4x + 9x + 36}[/tex]
Factorize the denominator
[tex]f(x) =\frac{x - 4}{x(x + 4) + 9(x + 4)}[/tex]
Factor out x + 9
[tex]f(x) =\frac{x - 4}{(x + 9)(x + 4)}[/tex]
Hence, the simplified expression of the function [tex]f(x) =\frac{x - 4}{x^2 + 13x + 36}[/tex] is

Compute the flux of the vector field F = xy, 5yz, 6zx through the portion of the plane 3x + 2y + z = 6 in the first octant with the downward orientation.
The plane has intercepts
y = z = 0 ⇒ 3x = 6 ⇒ x = 2
x = z = 0 ⇒ 2y = 6 ⇒ y = 3
x = y = 0 ⇒ z = 6
and thus passes through the points (2, 0, 0), (0, 3, 0), and (0, 0, 6).
Parameterize the portion of the plane (call it P) by the vector function,
[tex]\vec r(s,t) = \left\langle 2(1-s)(1-t), 3s(1-t), 6t \right\rangle[/tex]
where 0 ≤ s ≤ 1 and 0 ≤ t ≤ 1.
Compute the normal vector to P :
[tex]\vec n = \dfrac{\partial \vec r}{\partial t} \times \dfrac{\partial \vec r}{\partial s} = -\left\langle 18-18t, 12-12t, 6-6t \right\rangle[/tex]
Then the flux of F through P is given by the surface integral,
[tex]\displaystyle \iint_P \vec F \cdot d\vec S = \int_0^1 \int_0^1 \left\langle 6s(1-s)(1-t)^2, 90st(1-t), 72t(1-s)(1-t) \right\rangle \cdot \vec n \, ds \, dt \\\\ = - \int_0^1 \int_0^1 \left(108(t-1)^3 s^2 + 108(t-1)^2(5t+1) s + 432t(t-1)^2\right) \, ds \, dt \\\\ = - \int_0^1 18(t-1)^2(41t+1) \, dt \\\\ = \boxed{-\frac{135}2}[/tex]

The total cost for one year at the state university is $22,500. A student has the following help in covering the costs of school. . • An academic scholarship for $10,000. • Other scholarships and grants for $4,400. Parents pay $1,800, . What is the amount that the student will need to save every month in order to pay off the remaining costs in 10 months?
A) $630
B) $525
C) $1,200
D) $1,440
so her University costs are $22,500
however she gets some help because
◉ academic scholarship pays 10,000 off of that
◉ other scholarships pay 4,400 off of that
◉ and her parents pay 1800 off of that
what's left? well, what's left is 22500 - 10000 - 4400 - 1800 = 6300 bucks.
so for the next 10 months she needs to cover 6300 bucks of her expenses, now 6300 spread over 10 months is 630 a pop.

Answer:
The length is 19 inches
Step-by-step explanation:
Step 1: Determine the length
Perimeter = 2(L + W)
Step 2: Solve for L
60 /2 = 2(L + 11) / 2
