What expression represents the volume of the cone, in

denis23 [38]

The expression that represents the volume of the given cone, in cubic units is 2/3 πx³.

<h3>How to calculate the volume of the cone?</h3>

The volume of a cone with radius 'r' and slant height 'h' is

V = 1/3 π r² h

Unit: cubic units

<h3>Calculation:</h3>

The given cone has radius r = x and height h = 2x

Then, the volume of the cone is calculated by

V = 1/3 π r² h

= 1/3 π x² (2x)

= 2/3 π x³ cubic units

Therefore, the volume of the given cone is V = 2/3 π x³ cubic units.

So, option A is correct.

Find the area of the parallelogram that has a base of 2 1/2 ft and a height of 1 1/4ft

Marina CMI [18]

Answer:

The area of the parallelogram is $3\frac{1}{8}ft^{2}$

Step-by-step explanation:

Remember that a mixed fractions are composed for a whole number, a numerator and a denominator. For example in the mixed fraction $2\frac{1}{3}$ : 2 is the whole number, 1 is the numerator and 3 is the denominator.

If you want to convert to a improper fraction you need to multiply the whole number by the denominator and add to the numerator. The result will be the numerator of the improper fraction. The denominator remains the same.

$2\frac{1}{3}=\frac{(2*3)+1}{3} =\frac{7}{3}$

1. Convert the mixed fractions in the improper fraction type, as follows:

$Base= 2\frac{1}{2}=\frac{5}{2} \\ \\Height= 1\frac{1}{4}=\frac{5}{4}$

2. Replace the data in the equation of a parallelogram

$Area= Base*Height$

$Area= Base*Height\\Area=\frac{5}{2}ft *\frac{5}{4}ft\\Solve...\\Area=\frac{25}{8}ft^{2}$

3. Convert the improper fraction in a mixed fraction

$Area=\frac{25}{8}ft^{2}=3\frac{1}{8}ft^{2}$

The area of the parallelogram is $3\frac{1}{8}ft^{2}$

PLEASE ANSWER

oksano4ka [1.4K]

Answer:

x² + 9x + 8 = (x + 1)(x + 8)

x² + 9x + 8 = (x + 8)(x + 1)

Step-by-step explanation:

* Lets explain how to factorize the polynomial using the pattern

- The form of the quadratic polynomial is x² + px + q, where p is the

coefficient of x and q is the numerical term

∵ x² + (a + b)x + (ab) = (x + a)(x + b)

- From the formula above the coefficient of x is the sum of the two

factors a and b

∴ p = a + b and q = ab

- That means p is the sum of two numbers and q is the product of

the same numbers

* Lets solve the problem

∵ x² + 9x + 8 is a quadratic polynomial

∵ x² + px + q is the form of quadratic polynomial

∴ p = 9 and q = 8

∵ p = a + b and q = ab

∴ a + b = 9 ⇒ (1)

∴ ab = 8 ⇒ (2)

- We must to find two numbers their product is 8 and their sum is 9

∵ The possibility of 8 as a product of two numbers is:

2 × 4 OR 1 × 8

∵ The sum of 1 + 8 = 9

∴ The value of a and b are 1 and 8

- It does't matter which of them = 1 or which of them = 8

∴ x² + (a + b)x + ab = x² + (1 + 8)x + (1)(9)

∵ x² + (a + b)x + (ab) = (x + a)(x + b)

∴ x² + (1 + 8)x + (1)(9) = (x + 1)(x + 8)

∴ x² + 9x + 8 = (x + 1)(x + 8)

- OR

∴ x² + 9x + 8 = (x + 8)(x + 1)
