What is the remainder when the polynomial f(x)=3x^3-4x^2+2x+8 is divided by (x-5)

Answers

The remainder when the polynomial f(x) = 3x³ - 4x² + 2x + 8 is divided by (x - 5) is constant an equal f(5).

Substitute x = 5 to the polynomial:

[tex]f(5)=3(5^3)-4(5^2)+2(5)+8=3(125)-4(25)+10+8\\\\=375-100+18=275+18=293[/tex]

Answer: (3x³ - 4x² + 2x + 8) : (x - 5) = q(x) + 293.

Which correctly describes how the graph of the inequality −4y − x ≥ 7 is shaded?

Above the solid line
Below the solid line
Above the dashed line
Below the dashed line

Answers

Answer:

Below the solid line.

Step-by-step explanation:

When you solve for y, you will have a less than or equal to sign, so the shading is below the line.

Answer:

Below the solid line

Step-by-step explanation:

−4y − x ≥ 7

We need to solve for y

Add x to each side

−4y − x +x≥ 7+x

-4y   ≥ 7+x

Divide each side by -4.  Remember to flip the inequality

−4y/-4 ≤ (7+x)/-4

y ≤ -1/4 x - 7/4


Y is less than or equal to the value so the line is solid (equals sign)

and below  ( less than)

[tex]\angle T=\angle M;[/tex]

[tex]\overline {JP}[/tex] and [tex]\overline {BY}.[/tex]

Step-by-step explanation:

Similar figures have proportional corresponding sides and congruent corresponding angles. If parallelogram JSTP is similar to parallelogram BFMY, then

[tex]\angle J=\angle B;[/tex] [tex]\angle S=\angle F;[/tex][tex]\angle T=\angle M;[/tex][tex]\angle P=\angle Y;[/tex][tex]\dfrac{JS}{BF}=\dfrac{ST}{FM}=\dfrac{TP}{MY}=\dfrac{JT}{BM}=\dfrac{JP}{BY}=\dfrac{SP}{FY}.[/tex]

Answer:

Step-by-step explanation:

p=y

by looking at the end of the angles you can tell that P is corresponding to y

ST=FM

Alan has an annual base salary of $24,000. In addition to his salary, he earns 8% of his total sales (S). If he wants to earn at least $56,000 next year, how much does he need to sell?
A. S > $244,480
B. S > $550,000
C. S > $448,000
D. S > $400,000

Answers

Answer:

D. S > $400,000

Step-by-step explanation:

His salary is base salary plus commission

salary = 24000 + .08 sales

He wants a salary of at least 56000

56000<= 24000 +.08 sales

Subtract 24000

56000-24000<= 24000-24000+.08*sales

32000<= .08 * sales

Divide each side by .08

32000/.08 <= .08/.08 * sales

400000<= sales

74.362 to the nearest tenth

Answers

Answer:

73.4

Step-by-step explanation:

When they ask for the nearest tenth you check the hundreth, it its 5 or ore than you increase the tenth

The number 74.362 would round down to 74.4

For Rounding some number to a specific value is making its value simpler mostly done for better readability or accessibility.

Rounding to some place keeps it accurate on the left side of that place but rounded or sort of trimmed from the right in terms of exact digits.

We need to round  74.362 to the nearest tenth,

To round 74.362 to the nearest tenth, we need to look at the digit in the hundredth place, which is 2. Since 2 is less than 5, we round down and keep 4.

Therefore, rounding 74.362 to the nearest tenth gives us 74.4.

The hourly wage increase each employee receives each year depends on their number of years of service. Every three years of service means an increase of $0.50 per hour. So, employees that have been with the company for less than three years can expect to receive an increase of $0.50 per hour. Employees that have been with the company for at least three years, but less than six years can expect an increase of $1.00. Employees that have been with the company for at six years, but less than nine years, receive an increase of $1.50 per hour. And, employees of at least nine years, but less than twelve years receive an increase of $2.00. Write a function to represent this scenario.

Which are the x-intercepts of the graphed function?

Answers

-3 and 1 because that is the point in which the line crosses the x axis

Answer:  the correct option is

(B) (-3, 0) and (1, 0).

Step-by-step explanation:  We are given to find the x-intercepts of the graphed function.

We know that

x-intercepts of a function are the points on the X-axis through which the graph of the function is crossing.

From the graph, we see that

the curve is crossing the X-axis at the points (-3, 0) and (1, 0).

Therefore, the x-intercepts of the given function are (-3, 0) and (1, 0).

Option (B) is CORRECT.

You spent z dollars today. Today, you spent 5.5 times as many dollars as you spent yesterday. Which expression correctly shows how much you spent yesterday?



5.5z



5.5 ÷ z



5.5(1 − z)



z ÷ 5.5



none of the above

Answers

Answer:

Z ÷ 5.5

Step-by-step explanation:


The correct expression to show how much was spent yesterday when z dollars were spent today and that amount is 5.5 * the spending of yesterday is z divided by 5.5.  The correct answer is option (D) z ÷ 5.5.

If you spent z dollars today and that amount is 5.5 * what you spent yesterday, to find out how much you spent yesterday, you would divide the amount spent today by 5.5. This is because the relationship between what was spent today (z dollars) and what was spent yesterday is multiplicative. Today’s spending (z) is equal to 5.5 * yesterday’s spending, so to find out what you spent yesterday, you would express it as z divided by 5.5.

Thus, the correct answer to the student's question is option (D) z ÷ 5.5.
