Answer:

10+2x= the sum (anything could be put here)

Step-by-step explanation:

Well sum is automatically addition

Doubleing a number is basically multiplying it by 2

so

10+2x= whatever youw ant to put here

Answer:

(a) The area is 0.03 square miles

(b) The population density is 12000 people per square miles

Step-by-step explanation:

Given

See attachment for complete question

Solving (a): Area of Orchid Hill (in square miles)

The dimension of the neighborhood is 4 blocks by 3 blocks

Since each block are of the same dimensions

The area is calculated as:

[tex]Area = 4blocks * 3 blocks[/tex]

If [tex]20\ blocks = 1\ mile[/tex] then:

[tex]1\ block = \frac{1}{20} mile[/tex]

[tex]1\ block = 0.05mile[/tex]

So, we have:

[tex]Area = 4blocks * 3 blocks[/tex]

[tex]Area = 4 * 0.05 * 3 * 0.05[/tex]

[tex]Area = 0.03mi^2[/tex]

Solving (b): The population density of the neighborhood as people per square mile

From the question, we have:

[tex]People = 360[/tex]

[tex]Area = 0.03mi^2[/tex] --- calculated

So, the population density is:

[tex]Density = \frac{People}{Density}[/tex]

[tex]Density = \frac{360}{0.03}[/tex]

[tex]Density = 12000[/tex]

Answer: [tex]2514.28\ cm^3[/tex]

Step-by-step explanation:

Given

The height of the cylinder is [tex]h=8\ cm[/tex]

Circumference of the base is [tex]20\pi \ cm[/tex]

suppose 'r' is the radius of the cylinder

[tex]\Rightarrow 2\pi r=20\pi\\\Rightarrow r=10\ cm[/tex]

The volume of a cylinder is [tex]V=\pi r^2h[/tex]

[tex]\Rightarrow V=\pi \times 10^2\times 8=2514.28\ cm^3[/tex]

Answer:

(a) discriminant is positive, 76

(b) the above tells you there are two real roots

Step-by-step explanation:

the discriminant is 'b² - 4ac'

3x² - 2x - 6 = 0  ∴ a = 3, b = -2, c = -6

(-2)² - 4(3)(-6) = 4 + 72

(a) The discriminant of the quadratic equation is positive, 76.

(b) The quadratic equation tells you there are two real roots.

A quadratic equation is a polynomial with a degree of 2 or the maximum power of the variable is 2 in quadratic equations. It has two solutions as its maximum power is 2.

The discriminant of a polynomial in mathematics is a quantity that depends on the coefficients and enables inference of some root features without computing them.

Given that the quadratic equation 3x²-6=2x.

The discriminant Of the quadratic equation is calculated by the formula below:-

D = b² - 4ac

3x² - 2x - 6 = 0  ∴

a = 3, b = -2, c = -6

Put the value of the coefficient to get the value of the discriminant.

D = (-2)² - 4(3)(-6) = 4 + 72 = 76

Therefore, the discriminant of the quadratic equation is positive, 76, and the quadratic equation tells you there are two real roots

Step-by-step explanation:

The pythagorean theorem is the sum of the two legs squares equal the hypotenuse squared.

The hypotenuse is the longest side so 3.5 is our hypotenuse.

Apply formula to see of true.

[tex] {a}^{2} + {b}^{2} = {c}^{2} [/tex]

[tex] {2.5}^{2} + {3}^{2} = {3.5}^{2} [/tex]

[tex]6.25 + 9 = (3.5 {}^{2}) {?} [/tex]
