Step-by-step explanation:
By the question ;

Can someone help me with this question? I'm confused :(
The polynomial will have zeroes of
3, 4 + 2i, 4 - 2i, 1 + √7 and 1 - √7
So we have
(x - 3) (x - (4 + 2i) ) ( x - (4 - 2i) ) ( x - (1 - √7) ) ( x - (1 + √7) ) =
Breaking this down, we have
( x - (4 + 2i ) (x - ( 4 - 2i) = (x^2 -x(4 + 2i) - x (4 - 2i) + (4 + 2i) (4 - 2i) =
(x^2 -4x - 2ix - 4x + 2ix + 16 + 4) = ( x^2 - 8x + 20)
And
( x - (1 - √7)) ( x - ( 1 + √7) =
x^2 - x(1 - √7) - x ( 1 + √7) + (1 - √7) (1 + √7) =
x^2 - x + √7x - x - √7x + 1 - 7 =
(x^2 - 2x - 6)
So we have
(x - 3) ( x^2 - 8x + 20) (x^2 - 2x - 6) =
This expands to :
x^5 - 13 x^4 + 60 x^3 - 82 x^2 - 144 x + 360

Which equation can be used to find 75 percent of 200?
StartFraction 75 times 1 Over 200 times 1 EndFraction = StartFraction 75 Over 200 EndFraction
StartFraction 100 times 26.7 Over 75 times 2.67 EndFraction = StartFraction 267 Over 200.25 EndFraction
StartFraction 200 times 2 Over 100 times 2 EndFraction = StartFraction 400 Over 200 EndFraction
StartFraction 75 times 2 Over 100 times 2 EndFraction = StartFraction 150 Over 200 EndFraction
Answer:
Option DStep-by-step explanation:
A. StartFraction 75 times 1 Over 200 times 1 EndFraction = StartFraction 75 Over 200 EndFraction
75*1/200 = 75/200, INCORRECT, same number can't be 75% and 100% same timeB. StartFraction 100 times 26.7 Over 75 times 2.67 EndFraction = StartFraction 267 Over 200.25 EndFraction
100*26.7 / 75*2.67 = 267/200.25, INCORRECT, 75% of the number can't be greater than number itself (267 > 200)
C. StartFraction 200 times 2 Over 100 times 2 EndFraction = StartFraction 400 Over 200 EndFraction
200*2/100*2 = 400/200, INCORRECT, 75% of the number can't be greater than number itself (400 < 200)D. StartFraction 75 times 2 Over 100 times 2 EndFraction = StartFraction 150 Over 200 EndFraction

The population of a town changed by -17.4% over 4 years. What was the average change per year?
Fill in the blank.
ahh help plzzz
First, let’s look at the total increase - it’s either 100% (you added 150,000 to 150,000) or 50% (half of the 300,000 came in the last decade). Most often increases are described by the percentage of the starting amount, but the other convention can sometimes be used as well. For small percentages around 5% or lower, the two values will be almost the same, but in this case it makes a big different.
Answer:
-4.35% or -0.0435

Step-by-step explanation:
$80 -------- 5 hours
? --------- 7 hours
so 80 * 7 = x * 5
x = 80 * 7 / 5
x = 112

Sanji scored 125 points in the first round of a video game and 263 points in the second round. His total score after the third round was 557 points.
How many more points did Sanji score in the third round of the video game than in the first round?
Sanji scored 44 points more in third round as compared to the first round.
What is an Equation?An equation is a mathematical statement that is formed when two algebraic expressions are equated using an equal sign.
Sanji score in the first round of video game is 125 points
Sanji score in the second round of video game is 263 points
Let Sanji's score in the third round of video game is x points
Total score is 557 points
The equation is
125+ 263+ x = 557
388 + x = 557
x = 169 points
As compared to the first round Sanji scored = 169 -125 = 44 points more

Omg help with my homework PLEASE ASAP. what donu graph and how do i suow my workkkkk whats the answer
Answer:
you have to start with you b which in your problem is 5 so put a point at 5 on the y-axis on your graph. then with the M (the fraction numbers) you have to move either up or down depending if there is a negative number. so yours is 1/2 so then you would start at the 5 point and go up 1 and right 2 then you just keep repeating till you get a few points and can make a line then you just do the same thing for the other equation. start at 3 on the y-axis and then go up 3 and right 4 then just keep repeating till you get a few point and can create a line at the end the lines should cross each other like perpendicular lines

Answer: -9/1
Step-by-step explanation:
first covert 5 and 1/4 into an improper fraction
5x4 ( 5 one quaters) = 20 + the 1 remaining = 21
so 21/4
or 21 quaters
then divide .
but remeber these rules!
If the signs are the same (either both positive or both negative), then the answer is positive.
If the signs are different (one negative and one positive), the answer is negative.
so , our answer will be a negative
then
divide as usual
but when we divide we need to remeber to x by the reciprocal of our divisor
the divisor here is - 7/12
We can think of a whole number as being "number/1", so the reciprocal is just like "flipping it over"
-7/12 "flipping it over" is -12/7
so three rules
1- our answer will be negative
2- we are timesing by the reciprocal
FINAL ANSWER =
21/4 x -12/7
21 x 12 = 252
4 x7= 28
- 252/ 28 is the answer
Find the GCD (or HCF) of numerator and denominator
GCD of 252 and 28 is 28
Divide both the numerator and denominator by the GCD
252 ÷ 28
28 ÷ 28
Reduced fraction:
9
1
Therefore, 252/28 simplified to lowest terms is -9/1.

A square piece of cardboard was used to construct a tray by cutting 2-inch squares out of each corner and turning up the flaps. Find the size of the original square if the resulting tray has a volume of 128 cu in.
Answer:The original square was 10 x 10 inches
Step-by-step explanation:
Let L, W, and H stand for length, width, and height (in inches)
Volume = L*W*H
L*W*H = 128 in^3
H = 2 in
This is a square, so L = W
L*W*H = 128 in^3
W*W*(2in) = 128 in^3
W^2 = 64 in^2
W = 8 in
Add 2 in for the area that was used for the side.
The original square was 10 x 10 inches
