If f(x) = 4x^5 + 5x^3 +3, then what is the remainder when f(x) is divided by
X+2?
Answer: x2 + 4x + 9 on top, with a remainder of r(x) = 30
Step-by-step explanation:
The remainder of the division of the given polynomial by (x +2) is; -165.
What is the remainder of the division of the Polynomial by (x -2)?It follows from the task content that the remainder of the polynomial division is required.
On this note, the remainder of the division is the f(x) at x= -2.
f(-2) = 4(-2)⁵ + 5(-2)³ +3 = 4(-32) + 5(-8) + 3
f(-2) = -165.

5.) A car dealership has hired you to determine how many sales they can make based on how many flash sales they have in a quarter. You're able to determine that the data has a strongly linear positive association and a correlation value of r= 0.86. How should you state your findings?
OA. As the number of flash sales per quarter increases, car sales tend to increase.
OB. A dealership that sells more cars is probably holding more flash sales.
OC. Flash sales are proven to increase the number of car sales.
OD. Flash sales increase customer traffic, which will naturally lead to more vehicle sales.

one month Tammy rented 2 movies and 3 video games for a total of $25. The next month she rented 4 movies and 8 video games for a total of $61. Find the
rental cost for each movie and each video game.
Answer:
cost of each video game = $5.50
cost of each movie = $4.25.
Step-by-step explanation:
Let m represent cost per movie
g represents cost per video game.
Create two equations to represent the total cost Tammy rented movie and video games in each month, and solve simultaneously for each variable:
First month:
[tex] 2m + 3g = 25 [/tex] => equation 1
Second month:
[tex] 4m + 8g = 61 [/tex] => equation 2
Multiply equation 1 by 4, and multiply equation 2 by 2 to derive:
4 × [tex] 2m + 3g = 25 [/tex]
2 × [tex] 4m + 8g = 61 [/tex]
[tex] 8m + 12g = 100 [/tex] => equation 3
[tex] 8m + 16g = 122 [/tex] => equation 4
Subtract equation 4 from equation 3
You'd have:
- 4g = - 22
Divide both sides by -4
g = 5.5
Thus, the cost of each video game = $5.50.
Substitute g = 5.5 in equation 1 and solve for m.
[tex] 2m + 3g = 25 [/tex]
[tex] 2m + 3(5.5) = 25 [/tex]
[tex] 2m + 16.5 = 25 [/tex]
Subtract 16.5 from each side
[tex] 2m = 25 - 16.5 [/tex]
[tex] 2m = 8.5 [/tex]
Divide both sides by 2
[tex] m = 4.25 [/tex]
Thus, cost of each movie = $4.25.

An Internet site sells 120 types of cell phones. The ratio of the number of smartphones to the number of feature phones is 3:5. How many of the 120 types of cell phones are smartphones?
Use the on-screen keyboard to type your answer in the box below.
Answer:
Number of smartphones = 45
Step-by-step explanation:
Given:
Total number of phones = 120
Ratio [Smartphones to feature phones] = 3:5
Find:
Number of smartphones
Computation:
Number of smartphones = 120[3/(3+5)]
Number of smartphones = 120[3/(8)]
Number of smartphones = 360 / 8
Number of smartphones = 45

$20, 5.5% of 495 is 20.
b
$19.08. 5.5% of 495 is 19.08.
c
$27.23, 5.5% of 495 is 27.225.
Answer:
Step-by-step explanation:
The answer is $27.23 for the commission
Work out problem:
495×5.5%=27.225
So you round that off to 27.23

What is the slope in the Y intercept of the line on the graph below
slope= -4, Y intercept = 1
slope =-4, Y intercept = 4
slope = -1/4, Y intercept = 1
slope = -1/4, Y intercept = 4
Answer:
just by looking at the graph you can see that the y int is one, so that eliminates two answers already. Then the slope is rise over run. (best thing to remember in math. rise over run) so pick two points. (0, 1) and (4,0) were the first ones i saw. to get from those two points you go from (0,1) over 4 (thats your run) and from there down 1 (thats your rise) to get to (0,4). You would then do rise over run (and because your rise goes down its negative) to get -1/4 as your slope. The answer is slope= -1/4, Y intercept = 1
