factor of 9x2 18x + 8?
Factor of 9x^2-18x+8
Answers
Answer:
(3x - 2)(3x - 4).
Step-by-step explanation:
9x^2-18x+8
Use the 'ac' method:
9 * 8 = 72.
We need 2 numbers whose product is + 72 and whose sum is -18
These are -12 and -6 so we rewrite the expression as:
9x^2 - 12x - 6x + 8 Now we factor by grouping:
= 3x(3x - 4) - 2(3x - 4) The 3x - 4 is common so we have:
(3x - 2)(3x - 4).
The factor of the quadratic expression 9x² - 18x + 8 will be (3x - 2) and (3x - 2).
What is factorization?It is a method for dividing a polynomial into pieces that will be multiplied together. At this moment, the polynomial's value will be zero.
The quadratic expression is given below.
⇒ 9x² - 18x + 8
Factorize the quadratic expression, then the factors are given as,
⇒ 9x² - 18x + 8
⇒ 9x² - (12 + 6)x + 8
⇒ 9x² - 12x - 6x + 8
⇒ 3x(3x - 4) -2(3x - 4)
⇒ (3x - 2)(3x - 4)
Then the factor of the quadratic expression 9x² - 18x + 8 will be (3x - 2) and (3x - 2).

Answers
Caroline, Colin & Sarah share some money.
Caroline gets 1/9 of the money.
Colin and Sarah share the rest in the ratio 1:3.
What proportion does Sarah get?
Answers
Answer:
2 ÷ 3
Step-by-step explanation:
Let us suppose the money be 90
Since caroline gets 1 by 9 of the money i.e. 10
And, the remaining money would be distributed among Colin and sarah in the ratio of 1:3
So, the remaining money would be
= 90 - 10
= 80
So, the sarah could get
= 80 × 3 ÷ 4 ÷ 90
= 60 ÷ 90
= 20 ÷ 30
= 2 ÷ 3

Which statement about this table of values is true?
A.Because the rate of change is constant, the function is linear
B.Because the rate of change is constant, the function is nonlinear
C.Because the rate of change is not constant, the function is linear
D.Because the rate of change is not constant the function is nonlinear
Answers
Answer:
D
Step-by-step explanation:
If something is not constant we know it is non-linear. We know this is not constant because when graphed, the line is not straight.
Answer:
D.

Which histograms are approximately symmetric and bell shaped?
Answers
Answer:
B and E
Step-by-step explanation:
im pretty sure what you have is correct
The correct histograms that are approximately symmetric and bell-shaped are - histograms B, C, and E because they are symmetric and bell-shaped.
A histogram is a convenient form or graphical representation of the frequency distribution of numerical data by means of rectangles. These histograms are found in different shapes and symmetries.
Bell-shaped curve:
if a histogram resembles or looks like a “bell” by joining the interval of rectangles in a curve and has one single peak in the middle of the distribution.In the given histograms only histogram shows a bell-like curve when joining the middle point of rectangles of distribution and also present in symmetry.in the image attach approximate curves are form you can see if it is bell shape and symmetric.Thus, the correct answer is - Histograms B, C, and E.

Formula
a^2 + b^2 = c^2
a = 5
b = ?
c = 9
Solution
5^2 + b^2 = 9^2 Expand the givens
25 + b^2 = 81 Subtract 25 from both sides
25-25+b^2 = 81- 25
b^2 = 56
√b^2 = √56
b = √8*7
b = √2*2*2*7
b = 2 √2*7

In a large city’s recent mayoral election, 131,506 out of 309,153 registered voters actually turned out to vote. If 20 registered voters are randomly selected, find the probability that 7 of them voted in the mayoral election. Use a TI-83, TI-83 plus, or TI-84 calculator to find the probability.
Answers
The probability that 7 of them voted in the mayoral election using the calculator is 0.1455
What is probability?It is defined as the ratio of the number of favourable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.
The probability of registered voters actually turned out to vote:
= 131,506/309,153
p = 0.4254
n = 20
From the calculator:
P(X = 7) = 0.14546189
or
P(X = 7) = 0.1455
Thus, the probability that 7 of them voted in the mayoral election using the calculator is 0.1455

Step-by-step explanation:
A cuboid consists of 6 sides, 2 sides will be 9*6, 2 more will be 6*4, 2 more will be 6*9
So because there is 2 sides you will multiply the side by 2 so there is another side:
(6*9) * 2 = 108
(4*6) * 2 = 48
(4*9) * 2 = 72
108 + 48 + 72 = 228

What are the six trigonometric ratios?Trigonometric ratios for a right-angled triangle are from the perspective of a particular non-right angle.
In a right-angled triangle, two such angles are there which are not right angled(not of 90 degrees).
The slanted side is called the hypotenuse.
From the considered angle, the side opposite to it is called perpendicular, and the remaining side will be called the base.
The given function is f(x)= asin(b(x-h)) where we have to find the value of a , b and h.
f(x)= sin 2x – 3 cos 2x
If we substitute the value of a, b and h then we get the same solution for both the equation.
a = 3.16
b = 2
h = 0.62
Thus, option B is the correct match for the values.

6x – 5 y= 12
Answers
Answer:
hi
Step-by-step explanation:
We see a set of linear equations. Hence, a system of linear equations. So we solve them by process of elimination, multiplying the top equation by 5 to eliminate first such that
(2x+y=20)*5
6x-5y=12
-----------------------------------------
10x+5y=100
6x-5y=12
--------------------------------
16x = 112 .............After dividing 16 we get
x = 7
Now we plug x = 7 back into the original first equation to obtain the y value such that
2(7) + y = 20
12 + y = 20
-12 -12
------------------
y = 8
I hope this helped!
=(-2*5 + 10) - (-6*5 + 5*-4 + 12) + (5 + 8*-4 - 16)
= (-10 + 10) - (-30 - 20 + 12) + (5 -32 - 16)
= 0 - (-38) + (-43)
