Answer:

$\huge\boxed{\sf Volume = 48 \ ft^3}$

Step-by-step explanation:

Slant Height = 5 ft

<u>Finding Height using Pythagorean Theorem:</u>

$\sf c^2 = a^2 + b^2 \\\\Where \ c = 5 ft (Slant \ height) \ and\ b = 3 ft (Half \ of \ base)\ and\ a \ is\ height \\\\5^2 = a^2+3^2\\\\a^2 = 25-9\\\\a^2 = 16\\\\Taking \ sqrt \ on \ both \ sides\\\\Height = 4 \ ft$

$\rule[225]{225}{2}$

<u>Now, Finding the volume:</u>

$\sf Volume = a^2 \frac{h}{3} \\\\Where \ a \ is \ base \ edge \ and \ h \ is \ height\\\\Volume = (6)^2\frac{4}{3} \\\\Volume = 36 \frac{4}{3} \\\\Volume = 12*4\\\\\bold{Volume = 48 \ ft^3}$

$\rule[225]{225}{2}$

Hope this helped!

Given h(x) = 5x + 2, solve for 2 when h(x) = -8.

san4es73 [151]

Answer:

$\huge\boxed{\sf x = -2}$

Step-by-step explanation:

$\sf h(x) = 5x+2\\\\Put \ h(x) = -8\\\\-8 = 5x+2\\\\Subtract \ 2 \ to \ both \ sides\\\\-8-2 = 5x\\\\-10 = 5x\\\\Divide\ both \ sides \ by \ 5\\\\-10 / 5 = x \\\\x = -2 \\\\\rule[225]{225}{2}$

Hope this helped!

A store has clearance items that have been marked down by 60% they having a sale, advertising an additional 30% off clearance it

bagirrra123 [75]

The original price is 100% of the price. If the price is marked 60% off, then you pay 40% of the original price.

An item costs x dollars.

With the 60% off discount, it now costs 40% of x, or 0.4x.

Now you apply a 30% discount.

For the second discount, consider the price 0.4x to be the new original price. If the price is now discounted 30%, you will pay 70% of the new original price.

Start with 0.4x.

Now calculate 70% of 0.4x.

70% of 0.4x = 0.70 * 0.4x = 0.28x

After applying the 60% discount and the 30% discount, the item that originally cost x now costs 0.28x. 0.28x is the same as 28% of x. The amount you pay is 28% of the original price.

Answer: 28%

What are the possible numbers of positive, negative, and complex zeros of f(x) = −3x4 −

Anna007 [38]

Answer:

Step-by-step explanation:

We have to look at sign changes in f(x) to determine the possible positive real roots.

$f(x)=-3x^4-5x^3-x^2-8x+4$

There is only one sign change here, between the -8x and the +4. So that means there is only 1 possible real positive root.

Now we have to look at sign changes in f(-x) to determine the possible negative real roots.

$f(-x)=-3x^4+5x^3-x^2+8x+4$

There are 3 sign changes here. That means there are either 3 negative roots or 3-2 = 1 negative root. So we have:

1 positive

3 or 1 negative

We need to pair them up now with all the possible combinations.

If we have 1 positive and 1 negative, we have to have 2 imaginary

If we have 1 positive and 3 negative, we have to have 0 imaginary

Keep in mind that the total number or roots--positive, negative, imaginary--have to add up to equal the degree of the polynomial. This is a 4th degree polynomial, so we will have 4 roots.
