Use remainder theorem to find the remainder when the function f(x) = x^3 + 5x^2 - 7x is divided by (x+4)

murzikaleks [220]

Answer:

Remainder is 44.

Step-by-step explanation:

Remainder theorem says that if f(x) is divided by the linear polynomial (x-a) , then remainder is f(a)

In given question , f(x) = x³ + 5x² -7x

linear polynomial is (x+4) = (x - (-4) )

so from remainder theorem , remainder = f(-4) = (-4)³ + 5 ( -4)² - 7(-4)

= -64 + 80+28=44

Hence Remainder is 44.

The regular price of a sweater is $43.99. It is on sale for 20% off. What is the discount?

Greeley [361]

Answer:

Final price would be $35.19.... discount is $8.80.

Soulution:

Replacing the given values in formula (a) we have:

Amount Saved = Original Price x Discount in Percent / 100. So,

Amount Saved = 43.99 x 20 / 100

Amount Saved = 879.8 / 100

Amount Saved = $8.8 (answer).

In other words, a 20% discount for a item with original price of $43.99 is equal to $8.798 (Amount Saved)

the area of a circle is 28pi cm^2. find the area of a circle with a radius half the length of the original circle.

Verdich [7]

Answer:

The area of circle with radius half of original circle is 7 π cm² .

Step-by-step explanation:

Given as :

The Area of original circle = 28 π square centimeter

Let The radius of original circle = R

Let The area of circle with radius half of original circle = A square centimeters

Let The radius of circle with radius half of original circle = R'

Now, According to question

∵ Area of original circle = π × radius²

So, 28 π cm² = π × R²

Or, R² = $\frac{28\times \Pi }{\Pi }$

Or, R² = 28 cm²

∴ R = $\sqrt{28}$ cm

i.e R = 2 $\sqrt{7}$ cm

So, The radius of original circle = R = 2 $\sqrt{7}$ cm

<u>Again</u>

∵ The radius of circle with radius half of original circle = R'

So, R' = $\dfrac{R}{2}$

i.e R' = $\frac{2\sqrt{7}}{2}$

∴ R' = $\sqrt{7}$ cm

So, The area of circle with radius half of original circle = π × R'²

i.e A = π × R'²

Or, A = π ×( $\sqrt{7}$ ) ²

or, A = π × 7

So, The area of circle with radius half of original circle = 7 π cm²

Hence The area of circle with radius half of original circle is 7 π cm² . Answer
