Answer:

P(x) =x³-4x²-31x+70

Step-by-step explanation:

The function is expressed as:

P(x) = (x+5)(x-2)(x-7)

P(x) =(x²-2x+5x-10)(x-7)

P(x) = (x²+3x-10)(x-7)

P(x) = x³-7x²+3x²-21x-10x+70

P(x) =x³-4x²-31x+70

Hence the polynomial is P(x) =x³-4x²-31x+70

Answer:

A = $ 7,299.92

A = P + I where

P (principal) = $ 6,000.00

I (interest) = $ 1,299.92

Step-by-step explanation:

A = P(1 + r/n)^nt

Where:

A = Accrued Amount (principal + interest)

P = Principal Amount

I = Interest Amount

R = Annual Nominal Interest Rate in percent

r = Annual Nominal Interest Rate as a decimal

r = R/100

t = Time Involved in years, 0.5 years is calculated as 6 months, etc.

n = number of compounding periods per unit t; at the END of each period

In one week, we sold 184 baskets at $3.25 each. The following week, we reduced the price of the basket to $2.
8_murik_8 [283]

The number of baskets that were sold for $2 is 299 baskets.

<h3>What is a word problem?</h3>

A word problem is a method we used in denoting mathematical expressions and variables and it can be solved with the use of fractions, ratios, algebra, and arithmetic operations as the case may be.

From the given information:

  • If 184 baskets is sold for = $3.25;
  • and (x) baskets is sold for = $2

The number of baskets sold in the second week is obtained as follows

i.e.

x = (184 × 3.25)/2

x = 299 basket were sold for $2

Instructions: Given the vertex, fill in the vertex form of the quadratic function..
miskamm [114]

Answer:

\implies y=(x-2)^2-6

Step-by-step explanation:

<u>Vertex form of a quadratic equation</u>:

y=a(x-h)^2+k

where:

  • (h, k) is the vertex
  • a is some constant

<u>Given vertex</u>:  (2, -6)

⇒ h = 2 and k = -6

Substitute the values of h and k into the formula:

\implies y=a(x-2)^2+(-6)

\implies y=a(x-2)^2-6

As we have not been given a value for the constant a, assume this is 1.

Therefore, the <u>vertex form</u> of the <u>quadratic function</u> with vertex (2, -6) is:

y=(x-2)^2-6

The volume of the sphere is 904.32 m. To the nearest meter, what is the radius of the sphere????? Use 3.14 for pi.
Rus_ich [418]

Answer:

6

Step-by-step explanation:

The formula for the volume of a sphere is \frac{4}{3} \pi r^3. Plugging in the values that you are given, you get:

904.32=\frac{4}{3}\pi r^3

Dividing both sides by pi or 3.14:

288=\frac{4}{3}r^3

Dividing both sides by 4/3:

216=r^3

Taking the cube root of both sides:

r=6

Hope this helps!
