Based on the graph given, the point of the graph that corresponds with the shop's net worth when Sophie opened it is -5.

What is the minimum of a quadratic function?

The minimum value of the function is the place where the graph has a vertex at its lowest point. In the real world, you can use the minimum value of the quadratic function to determine the minimum cost and area.

What is the minimum amount?

we use minimum to describe an amount which is the smallest that is possible, allowed, and required.

What was the shop worth when it was opened?

The point of the shop were opened is represented by the value of the y axis when it was first crossed.

Answer:

26

Step-by-step explanation:

The mean of a set of number is the average the set of number, it is the ratio of the total sum of the terms to the sum of terms.

The standard deviation is the variation of a set of numbers to their mean. A low standard deviation means the value are close to the mean and a high standard deviation means the values are far from the mean. The standard deviation is given as:

[tex]\sigma=\sqrt{\frac{\Sigma (x_i-\mu)^2}{n} }\\ \\\mu=mean,n=number\ of\ terms, \sigma=standard\ deviation[/tex]

Given the numbers:

86, 81, 87, 82. mean = μ = 84

[tex]\Sigma(x_i-\mu)^2=(86-84)^2+(81-84)^2+(87-84)^2+(82-84)^2=4+9+9+4=26[/tex]

Sum of squared deviations = 26

The sum of the squared deviations of the scores from the mean is 26.

-----------------------

Thus:

[tex]S_{ds} = (86-84)^2 + (81-84)^2 + (87-84)^2 + (82-84)^2 = 4 + 9 + 9 + 4 = 26[/tex]

The sum of the squared deviations of the scores from the mean is 26.

Answer: 135, 45, and 135 are the three other angles

==================================================

Explanation:

For a parallelogram, we'll have opposite angles with the same measure. So if one angle is 45 degrees, then the opposite angle is also 45 degrees. The other two angles are 180-45 = 135 degrees each. Adjacent angles in a parallelogram add to 180 degrees.

Answer:

Diagram B

Step-by-step explanation:

This is because the line only goes through two points and many are dispered from the line, however diagram A and C have points fairly close to them

Visually inspecting the three scatterplots, the line of best fit does not accurately fit the points on the second graph. Hence, line of best fit should not have been drawn for the second graph as the relationship isn't linear.

The line of best fit minimizes the sum of the square of the mean distance between each point. Hence, the distance between the line and the best fit line should be as small as possible.

However, the second graph isn't linear, hence , a linear line cannot model the relationship.

Answer:

A

Step-by-step explanation:

So we have the function:

[tex]f(x)=y=\sqrt[3]{x-2}+8[/tex]

To find the inverse of the function, we can flip x and y and then solve for y. Therefore:

[tex]x=\sqrt[3]{y-2}+8[/tex]

Solve for y to find our inverse.

Subtract 8 from both sides:

[tex]x-8=\sqrt[3]{y-2}[/tex]

Cube each side. The right cancels:

[tex](x-8)^3=y-2[/tex]

Add 2 to both sides:

[tex]y=(x-8)^3+2[/tex]

Therefore, our inverse is:

[tex]f^{-1}(x)=(x-8)^3+2[/tex]

8 Feet below the surface

Step-by-step explanation:

If the salmon were initially 5 feet below the surface, and then travelled down an additional 3 feet from the initial 5, then the new position would be 8 feet down relative to the surface.

You can write this as -5 + -3 = -8, assuming that 0 represents surface level.

Cheers.

The distance of salmon from the surface of the water is 8 feet.

Calculate the answer using a math operator is referred to as a mathematical operation.

Basic mathematical operations are addition, multiplication, subtraction and division.

Given that,

The distance of school of salmon for the surface of the river = 5 feet.

Since, to escape a hungry bear, the school of salmon went down to 3 feet.

The position of the salmon to the surface = 5 + 3 = 8 feet.

The required distance of school of salmon from the surface of water is 8 feet.

Answer:

1,350,001 shares

Step-by-step explanation:

Barnaby corporation issued 2,700,00 shares of stock to its respective shareholders

A shareholder is required to own more than half of the share of the stock of a corporation inorder to have most of it.

This implies that the shareholder must have 50% + 1 inorder to attain the majority shares

Therefore, the number of shares that must by owned by a shareholder to have majority of the shares can be calculated as follows

= 50/100 × 2,700,000

= 0.5×2,700,000

= 1,350,000+1

= 1,350,001 shares

Answer:

To make equivalent fractions, what we have to do is multiplicate or divide the numerator or denominator by the same number.

In our case:

[tex]\frac{2}{5}=\frac{2*2}{5*2}=\frac{4}{10}[/tex]

[tex]\frac{2}{5}=\frac{2*6}{5*6}=\frac{12}{30}[/tex]

[tex]\frac{2}{5} = \frac{2*12}{5*12}=\frac{24}{60}[/tex]

That are only three examples, but there are infinite.

We could also obtain equivalent fractions dividing, for example, [tex]\frac{3}{9}[/tex]:

[tex]\frac{3}{9}=\frac{\frac{3}{3}}{\frac{9}{3}}[/tex] = [tex]\frac{1}{3}[/tex]

So far, segment CD is the same length as AB. So we can say AB = CD.

Let's keep going

Segment CE is composed of CD and DE, both of which are equal to AB. In other words, AB = CD = DE. Because CD = DE, and the two segments add up to CE, this must mean that CE is twice as long as CD. Therefore, CE is twice as long as AB.

Answer:

B.  -12.4 + 20.6s.

Step-by-step explanation:

Perimeter = 2*length + 2 * width

= 2(3.1s - 1.6) + 2(7.2s - 4.6)

= 6.2s + 14.4s - 3.2 - 9.2

= 20.6s - 12.4

= -12.4 + 20.6s.

[tex]\boxed{-12+20.6s}[/tex]

To find the perimeter of a shape, we add length + width + length + width (or length * 2 + width *2). So we would multiply the width, (3.1s - 1.6), and the length, (7.2s - 4.6), by 2, and then add them together to find the perimeter.

2(3.1s - 1.6) + 2(7.2s - 4.6)

This is equal to:

6.2s + 14.4s - 3.2 - 9.2

Simplified, this is equal to:

20.6s - 12.4

(We have to switch it around, but this answer is equal to option b.)

-12.4 + 20.6s

Tip: To simplify an equation, you add like terms. Like terms are numbers that have the same variables or exponents; for example, -4 and 3 are like terms, as well as 5^2 and 8^2. (Keep in mind, the variables and/or exponents have to be the same if you combine the like terms. Numbers with different variables and exponents can never be combined!)

Answer:

Step-by-step explanation:

So we have the expression:

Expand:

[tex]=\sqrt{(5ab)^2}\cdot\sqrt5[/tex]

The left term cancels:

[tex]=5|ab|\sqrt5[/tex]

Note that we need the absolute value bars because if a and/or b was negative in the original equation, they will turn positive. Thus, to keep things consistent, we must use the absolute value to make sure that a and b stays negative :)

Step-by-step explanation:

We'll use the following Pythagorean Identity:

Finding sin θ , we'll rearrange the formula as:

[tex]sin \theta = \sqrt{1 - cos^2 \theta}[/tex]

Given that cos θ = - 1 / 6

[tex]sin \theta = \sqrt{1 - (-\frac{1}{6} )^2} \\sin \theta = \sqrt{1-\frac{1}{36} } \\sin \theta = \sqrt{\frac{36-1}{36} } \\sin \theta = \sqrt{\frac{35}{36} } \\sin \theta = \frac{\sqrt{35} }{\sqrt{36} }\\ sin \theta = \frac{\sqrt{35} }{6}[/tex]
