F(x)=3x 2 +24x+48f, left parenthesis, x, right parenthesis, equals, 3, x, squared, plus, 24, x, plus, 48 What is the value of th

neonofarm [45]

Answer:

The discriminant of function is 0. There one distinct real number zero of $f(x)$ (repeated roots).

Step-by-step explanation:

We are given the following function in the question:

$f(x)=3x^2 +24x+48$

We have to calculate the discriminant of the function.

Comparing to

$f(x) = ax^2+bx+c$

We get,

$a = 3\\b=24\\c = 48$

Discriminant is given by:

$D = b^2-4ac$

Putting values, we get,

$D = (24)^2-4(3)(48) = 0$

Thus, the discriminant of function is 0.

Since, the discriminant is zero, the function have repeated real roots. Thus, one distinct real number zero of $f(x)$ .

Adam is ordering pizza for a company party that he needs to have catered. Company A charges $8 for each pizza and a delivery/set

Wittaler [7]

Answer:

Inequality is $8x+45 < 12x+5$ and value of x>10.

Step-by-step explanation:

Given : Adam is ordering pizza for a company party that he needs to have catered.

Company A charges $8 for each pizza and a delivery/set-up fee of $45. Company B charges $12 for each pizza and a delivery/set-up fee of $5.

To find : Which inequality can be used to find x, the least number of pizzas that can be ordered so that the total charge for Company A is less than the total charge for Company B?

Solution : Let x be the number of pizza

Company A charges $8 for each pizza and a delivery/set-up fee of $45.

Total charge of Company A is $8x+45$

Company B charges $12 for each pizza and a delivery/set-up fee of $5.

Total charge of Company B is $12x+5$

The total charge for Company A is less than the total charge for Company B

i.e, Inequality form $8x+45 < 12x+5$

$\Rightarrow 45-5< 12x-8x$

$\Rightarrow 40< 4x$

$\Rightarrow \frac{40}{4}< x$

$\Rightarrow 10< x$

or x> 10

Therefore, Inequality is $8x+45 < 12x+5$ and value of x>10.

A rectangular Corn Hole area at the recreation center has a width of 5 feet and a length of 10 feet. If a uniform amount is adde

almond37 [142]

1. The formula for calculate the area of a rectangle, is:

A=LxW

A is the area of the rectangle
L is the length of the rectangle.
W is the widht of the rectangle

2. You have that:

-The rectangular Corn Hole area has a width of 5 feet and a length of 10 feet, so:

L1=10 feet
W1=5 feet

- When a uniform amount is added to each side (x), the area is increased to 84 feet². Then, you have a different length (L2) and a different width (W2):

3. The new length is:

L2=L1+x+x
L2=L1+2x
L2=10+2x

4. The new width is:

W2=W1+x+x
W2=W1+2x
W2=5+2x

5. The new area is:

A2=84 feet²

6. Then, you have:

A=LxW
84=(10+2x)(5+2x)

7. When you apply the distributive property, you obtain a quadratic equation:

4x²+30x-34=0

8. You can solve with by applyin the quadratic formula:

x=(-b±√(b^2-4ac))/2a

a=4
b=30
c=-34

9. Then, the answer is:

x=1 feet

The volume of a stack of identical circular drink coasters, each 1 centimeter thick, can be found using the function v(r)=8(3.14

Vladimir79 [104]

The volume of a stack of identical circular drink coasters, each 1 centimeter thick, can be found using the function v(r)=8(3.14)(r)^2, where r is the radius of a coaster. What does the constant 8 in the function represent?

The constant 8 represents the height of the stack and hence the number of coasters.
