Which describes the graph of y = −(x − 3)2 − 8?

The answer of 2nd question Quadrilateral JUMP in a circle is  = Supplementary

What do you mean by Supplementary angle?

Supplementary angles are two angles whose measures add up to 180 degrees. In other words, if angle A and angle B are supplementary, then A + B = 180 degrees.

Supplementary angles are important in geometry and trigonometry, and they can be used to solve various problems involving angles and their measures. For example, if you know that two angles are supplementary and you know the measure of one of them, you can find the measure of the other by subtracting the measure of the known angle from 180 degrees.

Using the formula we know that the volume of the oblique rectangular prism is 1,200units³ respectively.

A prism with oblique bases is one in which the bases are not parallel to one another.

An oblique rectangular prism is a rectangular prism with bases that are not arranged one over the other.

The following qualities describe an oblique prism: It seems to be slanted or skewed. Parallelograms make up an oblique prism's faces.

The height is gauged from the outside.

The two bases are not positioned next to one another exactly.

So, the volume formula for the oblique rectangular prism:

V=l⋅w⋅h

Now, insert values:
V=l⋅w⋅h

10b = 62 - 12

10b = 50

b = 50/10

b = 5

Answer:

5

Step-by-step explanation:

When trying to find the value of an unknown variable, it is important to take into factors on how to reverse an effect being done to the variable, which is how we can isolate b and figure out the value.

- Addition reverses subtraction

- Multiplication reverses division

We have a simple equation, [tex]10b+12=62[/tex] , and we need to work around the variable b in order to isolate it. By doing this, we are able to find the true value of b.

We can subtract 12 on each side to get the term away from the constant.

[tex]10b+12=62[/tex]

     -   12   -12

[tex]10b=50[/tex]

Then, to isolate the variable from the coefficient, which is 10, we can divide it to negate the multiplication factor on the term.

[tex]\frac{10b}{10} = \frac{50}{10}[/tex]

b=5

Therefore, the variable b=5.

The final answer is:

-1/7 < 5 < 2

Or, in interval notation:

(−1/7, 2)

What is interval?

In mathematics, an interval is a set of real numbers with the property that any number that lies between two numbers in the set is also included in the set. An interval can be written using interval notation, which uses parentheses, square brackets, or a combination of both to indicate whether the endpoints of the interval are included or excluded. For example:

First, let's simplify the expression inside the parentheses:

3 + 2 = 5

Now we can substitute this value into the expression and simplify further:

-14 < -7(5) < 1

-14 < -35 < 1

To solve this compound inequality, we need to isolate the variable (in this case, there is no variable) to find the range of values that satisfy the inequality. We can do this by dividing all three parts of the inequality by -7. However, we need to reverse the direction of the inequality signs since we are dividing by a negative number:

-14/-7 > -35/-7 > 1/-7

2 > 5 > -1/7

Therefore, the solution to the inequality is:

-1/7 < 5 < 2

In interval notation, this can be written as:

(−1/7, 2)

To sketch the solution, we can plot the interval on a number line. The interval does not include the endpoints, so we use open circles to indicate this:

<-------------(○======○)------------->

             -1/7    5     2

The open circle at -1/7 indicates that -1/7 is not included in the interval, and the open circle at 2 indicates that 2 is also not included in the interval. The line segment between the circles represents the range of values that satisfy the inequality.

The two skaters might collide at the points (1, 12) and (7, 0).

What are the collide points?

To find the points where the two skaters might collide, we need to find the values of x and y that satisfy both equations simultaneously.

Setting the two expressions for y equal to each other, we get:

-2x + 14 = -2x² + 14x

Simplifying this equation, we get:

2x² - 16x + 14 = 0

Dividing both sides by 2, we get:

x² - 8x + 7 = 0

This equation can be factored as:

(x - 1)(x - 7) = 0

Therefore, the possible values of x where the skaters might collide are x=1 and x=7.

To find the corresponding values of y, we can substitute each value of x into one of the original equations.

For x=1, we get:

y = -2(1) + 14 = 12

Therefore, one possible point of collision is (1, 12).

For x=7, we get:

y = -2(7)² + 14(7) = 0

Therefore, another possible point of collision is (7, 0).

Therefore, To find the points where the two skaters might collide, we need to find the values of x and y that satisfy both equations simultaneously.

Setting the two expressions for y equal to each other, we get:

-2x + 14 = -2x² + 14x

The confidence interval does not justify the councilman's statement because 45 minutes is greater than the upper bound of the confidence interval.

What is a confidence interval?

A confidence interval is a statistical range that is used to estimate an unknown population parameter based on a sample from that population. It is a measure of the degree of uncertainty or precision associated with the estimated value of the parameter.

The confidence interval of 34.42 ± 8.14 minutes means that we are 95% confident that the true population mean commute time falls between 26.28 minutes (34.42 - 8.14) and 42.56 minutes (34.42 + 8.14). Since the councilman's statement of 45 minutes falls outside of this range, we cannot say that it is justified by the confidence interval.

Additionally, the fact that the mean commute time from the sample of 25 adults was 34.42 minutes does not necessarily mean that the true population mean commute time is also 34.42 minutes. It only provides an estimate, and the confidence interval takes into account the variability of the sample mean.

According to the given information, f(125) is equal to 48479.

What is function?

A function is a relation between a set of inputs and a set of possible outputs, with the property that each input is related to exactly one output.

To find f(125), we need to apply the recursive formula for f(n) when n is a positive integer divisible by 5. Since 125 is divisible by 5, we can use the formula:

f(125) = f(125/5) + 3(125)²

f(125/5) = f(25) = f(25/5) + 3(25)²

f(25/5) = f(5) = f(5/5) + 3(5)²

f(5/5) = f(1) = 4

Now we can substitute the values back into the formula and simplify:

f(5) = f(5/5) + 3(5)² = 4 + 75 = 79

f(25) = f(25/5) + 3(25)² = 79 + 3(625) = 2054

f(125) = f(125/5) + 3(125)² = 2054 + 3(15625) = 48479

Therefore, f(125) is equal to 48479.

Answer:

they bought 8 candy bars and 8 + 4 = 12 packs of gum.

Step-by-step explanation:

Let's use algebra to solve this problem:

Let x be the number of candy bars they bought.

Then, the number of packs of gum they bought is x + 4.

The total cost of the candy bars is 60x cents.

The total cost of the packs of gum is 85(x + 4) cents.

We know that they spent $15.00, which is 1500 cents, so we can write an equation:

60x + 85(x + 4) = 1500

Simplifying the equation, we get:

145x + 340 = 1500

145x = 1160

x = 8

Therefore, they bought 8 candy bars and 8 + 4 = 12 packs of gum

Answer: 22

Step-by-step explanation:

The number of the gum is 13 and the number of the candy will be 22.

What is linear system?

A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.

Jane and Sophia went to the corner store where packages of gum cost 54¢ each and candy bars cost 88¢ each.

They spent $26.38 total and bought 35 items total.

Let x be the number of the gum and y be the number of the candy.

Then the equation will be

x + y = 35 ...1

0.54x + 0.88y = 26.38 ...2

By solving the equations 1 and 2, then we have

x = 13 and y = 22

Then the number of the gum is 13 and the number of the candy will be 22.

The area of the purse can be calculated using the formula for the area of a trapezoid. The purse (not including the handle) takes up 34 cm² in the magazine layout.

The formula states that the area of a trapezoid is equal to one half of the product of the length of the two parallel sides, multiplied by the height. Thus, the area of the purse can be calculated as:

Area = (1/2) x (11cm + 6cm) x 4cm

Area = (1/2) x (17cm) x 4cm

Area = 34 cm²

Therefore, the purse (not including the handle) takes up 34 cm² in the magazine layout.

It is important to note that the formula for the area of a trapezoid can be used in this instance because the purse has a shape of a trapezoid.

This is due to the fact that the line parallel to the 11cm base has a length of 6cm. The line is not parallel to the 4cm height and thus, the shape of the purse is a trapezoid and not a rectangle.
