Does anyone know how to do this?

By simplifying given phrase "twice the sum of a number cubed and nine" and  evaluating it for r = 3 we got that Jessica done it correctly

Cube of any number means multiplying that number with itself 3 times.

For example [tex]3^3=3\times3\times3=27[/tex]

Here given phrase is

twice the sum of a number cubed and nine

let number be r

We can write it as

[tex]2(r^3+9)[/tex]

Now evaluating it for r=3

[tex]2(3^3+9)[/tex]

Now we can simplify it as

[tex]2(27+9)\\\\=(36)\\\\=72[/tex]

I hope this helps!

51 inches tall is Kelly .

In mathematics, multiplication is a method of finding the product of two or more numbers. It is one of the basic arithmetic operations, that we use in everyday life.

Here, we have,

Kelly is 4 feet , 3 inches tall.

We know that,

1 foot = 12 inches

Convert the feet given to inches: 4 × 12 = 48

48 + 3 = 51 inch.

Hence, 51 inches tall is Kelly .

The value of the tangent when the angle is from 180 to 270 is 0.9392. Then the correct option is B.

Trigonometry deals with the relationship between the sides and angles of a right-angle triangle.

If sine Θ almost equals negative 0.7660.

Then the angle will be

[tex]\theta = sin ^{-1} (-0.7660)\\\\\theta = -49.996^o[/tex]

The interval of the angle is from 180 degrees to 270 degrees. Then we have to add 270 degrees in the angle. Then the angle will be

[tex]\theta = -49.996^o + 270^o\\\\\theta = 220.0039^o[/tex]

Then the tangent of Θ will be given as

[tex]tan \theta = tan \ (220.0039^o) = 0.8392[/tex]

How do I find the equation of the line y=mx + C, passing through the points M (-2, -3) and T (3, 7)?

How do I find the equation of the line y=mx + C, passing through the points M (-2, -3) and T (3, 7)?

A2A

y = mx + C is often called slope-intercept form.

There are two pieces of information you will need to solve for. #1: The slope, which is m, and #2: the y-intercept, which is C (incidentally I learned this as y = mx + b, instead of y = mx + C, but that is a trivial detail)

Step #1 Find the slope. use the formula slope = (y₂ - y₁)/(x₂ - x₁) => (7 - -3)/3 - -2) = 10/5 = 2. m=2

Step #2 Find the y-intercept. Solve for y = mx + C when x is 2 and x = -2 and y = -3 -3 = 2(-2) + C => -3 = -4 + C add 4 to both sides, 1 = C

Equation: y = 2x + 1.

Check: x = 3 => y = 2(3) + 1 => y = 6 + 1 => y = 7 => (3, 7)

Check: x = -2 => y = 2(-2) + 1 => y = -4 + 1 => y = -3 => (-2, -3)

Answer:

[tex]P(Yellow\ or\ Green) = 0.524[/tex]

Step-by-step explanation:

Given

[tex]Yellow = 5\ seconds[/tex]

[tex]Green = 50\ seconds[/tex]

[tex]Red = 50\ seconds[/tex]

Required

Determine the probability of Green or Yellow

First, we need to determine the total time

[tex]Total = 50 + 50 + 5[/tex]

[tex]Total = 105\ seconds[/tex]

Next, is to determine the required probability

This is calculated as follows:

[tex]P(Yellow\ or\ Green) = P(Yellow) + P(Green)[/tex]

[tex]P(Yellow\ or\ Green) = \frac{n(Yellow)}{Total} + \frac{n(Green)}{Total}[/tex]

[tex]P(Yellow\ or\ Green) = \frac{5}{105} + \frac{50}{105}[/tex]

[tex]P(Yellow\ or\ Green) = \frac{5 + 50}{105}[/tex]

[tex]P(Yellow\ or\ Green) = \frac{55}{105}[/tex]

[tex]P(Yellow\ or\ Green) = 0.52380952381[/tex]

[tex]P(Yellow\ or\ Green) = 0.524[/tex] -- Approximated

The dimensions of the rectangular area of Tina's fence is 40 ft by 40 ft

where

l = length

w = width

She wants to create a rectangular area of 1,600 square feet for her pet . Therefore,

lw = 1600

Therefore,

perimeter = 160 ft

Then,

perimeter of rectangle = 2(l + w)

160 = 2(l + w)

l + w = 80

Let's combine the equations

lw = 1600

l + w = 80

l = 80 - w

Therefore,

w(80 - w) = 1600

80w - w² = 1600

Therefore,

w² - 80w + 1600 = 0

w² - 40w - 40w + 1600 = 0

w(w - 40) - 40(w - 40) = 0

(w - 40)(w - 40) = 0

w = 40 or 40

Therefore, the dimensions can be calculated as follows:

lw = 1600

40l = 1600

l = 1600 / 40

l = 40 ft

Therefore, the dimensions are 40ft by 40 ft

Answer:

2/3.

Step-by-step explanation:

Geometric mean  = √(2 * 2/9)

= √(4/9)

= 2/3.

The geometric mean between 2 and 2/9 is 2/3.

We can define the mean of the given data set as the average of all the

numbers. Mathematically, we can write mean as -

M = ∑x{i}/n

Given is to find the geometric mean between 2 and 2/9.

The general formula used to calculate the geometric mean is -

[tex]$\left(\prod _{i=1}^{n}x_{i}\right)^{\frac {1}{n}}={\sqrt[{n}]{x_{1}x_{2}\cdots x_{n}}}[/tex]

We can write the geometric mean between 2 and 2/9 as -

GM = √(2 x 2/9)

GM = √(4/9)

GM = √4/√9

GM = 2/3

Therefore, the geometric mean between 2 and 2/9 is 2/3.
