the polynomial p(x) has factors of x-5 and x-8. Which must be correct ?
Answer:
Find an answer to your question The polynomial p(x) has factors of x – 5 and x + 8. Which MUST be correct?
Step-by-step explanation:
If x – a is indeed a factor of p(x), then the remainder after division by x – a will be ... the polynomial (courtesy of the Remainder Theorem), but x – a is also a factor ... completed division: 2 2 5 0 7 ... x + 4 is a factor of 5x4 + 16x3 – 15x2 + 8x + 16.

Which complex number is equivalent to the given expression (2+I)(8-3i)-(23+34i)
Answer: -4 - 32i
i just took this test
The complex number is equivalent to the given expression (2+I)(8-3i)-(23+34i) is -32i-12.
The given expression is (2+i)(8-3i)-(23+34i).
What is a complex number?A complex number can be visually represented as a pair of numbers (a, b) forming a vector on a diagram called an Argand diagram, representing the complex plane.
Now, apply the distributive property and multiply each term of the first complex number with each term of the second complex number.
That is, (2+i)(8-3i)=8+8i-6i-3i²=8+2i+3 (∵i²=-1)
Now, 2i+11-23-34i=-32i-12
Therefore, the complex number is equivalent to the given expression (2+I)(8-3i)-(23+34i) is -32i-12.

During the 2011-12 NBA season, LeBron James had an average of 30.3 points per game. The mean and standard deviation for the league were 7.65 points per game and 6.64 points per game, respectively. That same season the WNBA was led by Diana Taurasi who averaged 21.6 points per game. The mean and standard deviation for the entire WNBA that year were 8.13 points per game and 4.77 points per game, respectively. Who had the more remarkable performance compared to the rest of their league
Answer:
LeBron James had the more remarkable season
Step-by-step explanation:
Given that:
LeBron James:
Average point per Game = 30.3
Mean of the league (m) = 7.65
Standard deviation (s) = 6.64
WNBA:
Taurasi:
Average point = 21.6
Mean = 8.13
Standard deviation =4.77
Taking the Zscore for each:
LeBron :
Zscore = (x - m) / s
Zscore = (30.3 - 7.65) / 6.64
Zscore = 22.65 / 6.64 = 3.411
P(z < 3.411) = 0.99968
Taurasi :
Zscore = (x - m) / s
Zscore = (21.6 - 8.13) / 4.77
Zscore = 13.47 / 4.77
Zscore = 2.82
P( Z < 2.82) = 0.9976
LeBron's average has more standard deviations above the mean than Taurasi

Two trains leave a station, one headed due west and the other headed due south. How fast is the southern bound train moving if the west bound train is 15 miles from the station traveling at a constant speed of 35 mph, the distance between the trains is 24 miles, and the distance between them is increasing at a rate of 25 mph.
Answer:
dx/dt = 4 mph
Step-by-step explanation:
The two trains, with the station ( origin of the coordinates system) all, form a right triangle when we considered the distance between the two trains.
In that triangle:
distance between trains D = 24 miles
leg (1 ) distance of train going west to origin y = 15 miles
leg (2) distance of train going south x = ??
When d = 24 and y = 15
D² = y² + x² ⇒ x² = D² - y²
x = √ (24)² - (15)²
x = √351
x = 18,73 miles
Now according to Pythagoras theorem
D² = x² + y²
Taking derivatives (respect to time) on both sides of the equation we get
2*D*dD/dt = 2*y*dy/dt + 2*x*dx/dt
In this expression we are looking for dx/dt, all the rest of variables are known
2*24*25 = 2* 15*35 + 2*(18,73)* dx/dt
(1200 - 1050 )/37,46 = dx/dt
dx/dt = 4 mph
Brandon is deciding between two truck rental companies. Company A charges an initial fee of $75 for the rental plus $2 per mile driven. Company B charges an initial fee of $35 for the rental plus $3 per mile driven. Let AA represent the amount Company A would charge if Brandon drives xx miles, and let BB represent the amount Company B would charge if Brandon drives xx miles. Write an equation for each situation, in terms of x, and determine which company would be cheaper if Brandon needs to drive 45 miles with the rented truck.
Answer:
-Equations:
AA=75+2x
AA=75+2x
-Company A would be cheaper.
Step-by-step explanation:
-Company A: The equation would indicate that the amount the company would charge is equal to the initial fee for the rental plus the cost per mile driven for the number of miles driven:
AA=75+2x
AA=75+2(45)
AA=75+90
AA=165
-Company B: The equation would indicate that the amount the company would charge is equal to the initial fee for the rental plus the cost per mile driven for the number of miles driven:
BB=35+3x
BB=35+3(45)
BB=35+135
BB=170
According to this, if Brandon needs to drive 45 miles with the rented truck, Company A would charge $165 and Company B would charge $170 which means that Company A would be cheaper.

[tex] \frac{7}{9} - \frac{2}{8} \times \frac{4}{9} \\after \: simlifying \\ \frac{7}{9} - \frac{1}{9} = \frac{6}{9} = \frac{2}{3} [/tex]
The monthly cost of running a small business consists of retail space rental at $2400, wages at $1800 and utilities at $480. If the retail space rental and wages are decreased by 5% and 6% respectively, while utilities are increased by 7%, find the percentage increase or decrease in the monthly cost of running the business.
Answer:
5.8%
Step-by-step explanation:
For the business,
retail space rental = $2400
wages = $1800
utilities = $480
Total running cost = $4680
But,
retail space rental decreased by 5%, so that;
5% of $2400 = 0.05 x $2400 = $125
The new retail space rental = $2400 - $125
= $2275
wages decreased by 6%, so that;
6% of $1800 = 0.06 x $1800 = $108
The new wages = $1800 - $108
= $1620
Utilities increased by 7%, so that;
7% of $480 = 0.07 x $480 = $33.6
The new amount on utilities = $480 + $33.6
= $513.6
New total running cost = $2275 + $1620 + $513.6
= $4408.6
The percentage decrease in the monthly cost = [tex]\frac{(4680 - 4408.6)}{4680}[/tex] x 100%
= [tex]\frac{271.4}{4680}[/tex] x 100%
= 5.8%

Answer:
2.685 + 2.685 + 2.685 + 2.685 + 2.685 + 2.685. . . . . 102 times.
Step-by-step explanation:
Think of this as 102 times of 2.685.
So you would add 2.685 together 102 times.
