Find f(−1) given that f(x)=x3+2x2+3x+4. <br>A. 10 <br>B. -2 <br>C. 2 <br>D. -10
Finger [1]

Answer:

The answer is option C

Step-by-step explanation:

f(x) = x³ + 2x² + 3x + 4

To find f(-1) substitute the value of x that's

- 1 into f(x)

That's

<h3>f( - 1) =  ({ - 1})^{3}  + 2 ({ - 1})^{2}  + 3( - 1) + 4 \\  =  - 1 + 2(1)  - 3 + 4 \\  =  - 1 + 2 - 3 + 4 \\  = 1 - 3 + 4</h3>

We have the final answer as

<h3>f( - 1) = 2</h3>

Hope this helps you

The Todd family plans to start a small business. Mr. Todd borrows $10,000 from the blank at an annual interest rate 8%for 36 mon
Ede4ka [16]

Answer: They will end up paying $2,400.

Step-by-step explanation:

Since the annual interest rate is 8% of $10,000, take 8% of 10,000 by multiplying these numbers. This gives you $800.

This is only the annual interest rate, the Todd family's loan and interest isn't paid until 36 months have passed. Since 36 months is equal to 3 years, we can multiply the annual rate by 3. (800*3)

The Todd family will pay $2,400 in interest by the end of the period.

Follow the steps to find the area of the shaded region.
victus00 [196]

The area of the sector, to 4 decimal places, is 78.6794 cm².

We have given that,

Sector Area= ( angle of sector/360). R2

We have to determine the Sector Area

<h3>What is the Area of a Sector of a Circle?</h3>

Area of sector = ∅/360 × πr².

We have given the following:

∅ = 46°

Radius (r) = 14 cm

Area of sector = 46/360 × π(14²)

Area of sector ≈ 78.6794 cm²

The area of the sector is approximately 78.6794 cm².

Please select the best answer from the choices provided .
lianna [129]

Answer: B: (1-5x²)³, all real numbers

Step-by-step explanation:

The notation f\circ g(x) is called function composition, which is where you pass one function in as the value of another function. In other words, \( f\circ g(x)=f(g(x)) \).

Since we have the values for f(x) and g(x), let's plug them in.

f(g(x))\\f(1-5x^2)\\(1-5x^2)^3

Hence, the best answer choice is B, as all real numbers would work and it is the cube of 1 - 5x².

The club sold shirts and capes to raise money for new stage equipment. The club sold each shirt for $20.00. The club made profit
Butoxors [25]

Answer:

The club made a profit of $96 from the shirt sale.

Step-by-step explanation:

First, you have to find the number of shirts sold by dividing the total amount sold by the price per shirt:

480/20=24

Now, that you know the number of shirts that were sold, you can multiply the profit per shirt for the number of shirts sold:

4*24=96

According to this, the answer is that the club made a profit of $96 from the shirt sale.
