Select the correct answer.What is the range of Piecewise and Absolute Value Functions

onIn order to solve this, we have to add the number of floors the elevator goes up and subtract the number of floors the elevator goes down, like this:

Initially, it goes down 9 floors since it was at the 10th floor we get:

10 - 9 = 1

Then, after it goes down 9 floors it gets to the first floor, then it goes up 19 floors , now we get:

1 + 19 = 20

After it goes up to the 19th floor from the fits one, it gets to the 20th floor, then it goes down 3 floors, now we get:

20 - 3 = 17

After it goes down 3 floors it gets to the 17th floor, then it goes 12 floors down from the 17th floor:

17 - 12 = 15

At the end, the elevator ends up in the 15th floor

Answer

Angle JLK = 31°

Explanation

To answer this, we will use the tangent-chord theorem.

So, the intercepted arc JNL has an angle 298°

Then, we can solve for the tangent chord angle next to it, Angle JLM first by saying

Angle JLM = (Intercepted arc JNL)/2

Angle JLM = (298°/2)

Angle JLM = 149°

Then, we can see that Angle JLM and Angle JLK lie on the same straight line, KLM.

Sum of angles on a straight line is 180°.

Angle JLK + Angle JLM = 180°

Angle JLK + 149° = 180°

Angle JLK = 180° - 149°

Angle JLK = 31°

the greatest commmon factor of 56 and 32 is 8

so in order to use the distributive property

8(7+4)=56+32=88

Solution:

The expression f(0) represents the y-intercept on the graph of f(x). The y-intercept of a graph is the point where the graph crosses the y-axis.

Thus, from the graph;

In order to calculate the volume of a cylinder, we can use the following formula:

Where r is the base radius and h is the height.

If the circumference is 8, we have:

Now, calculating the volume, we have:

So the correct option is the second one.

The volume of the tank can be calculated using the Volume of a cylinder formula, which is:

Where:

v = volume;

r = radius;

h = height.

In this exercise:

r = Diameter/2 = 12/2 = 6 ft

h = 16 ft

So, substituting the values:

Using π = 3.14:

Answer:

The volume of the tank is 1809 ft³.

Let:

Answer:

70/100

Explicación:

2 fracciones son iguales si una de ellas puede ser calculada multiplicando el numerador y el denominador de la otra por el mismo número.

Por lo tanto, 7/10 es equivalente a:

Multiplicamos por 10 arriba y abajo para que el denominador fuera 100. De este modo obtemos que 7/10 es igual a 70/100.

Here, we need to remember the signs rules

Answer:

x = 16

Step-by-step explanation:

sqrt x   + 3  = 2 sqrt x - 1         subtract sqrt x from both sides

3    =   sqrt x   -1                    add 1 to both sides

4 = sqrt x               square both sides

16 = x

Answer:

11.2cm

Explanation:

To be able to determine the missing length, we have to apply the Pythagorean Theorem which states that, in a right-angled triangle, the square of the hypotenuse(the longest side) is equal to the sum of squares of the other two sides.

Let's go ahead and find b as follows;

Answer:

0.0625 or [tex]\frac{1}{16}[/tex]

Step-by-step explanation:

If the water level decreases at a constant rate, then that just means that the relationship between the water level and time is linear or is a straight line if graphed.

let's just say that: [tex]C = \text{ contant rate the water level dropped at each hour}[/tex]

this means if we added C by how many hours passed, we should get the amount the water level dropped: [tex]C+C+C+C\text{...how many hours passed} =\frac{7}{12}[/tex]

let's also just say that: [tex]H = \text{ amount of hours that passed}[/tex]

from here we can rewrite the equation using multiplication: [tex]CH = \frac{7}{12}[/tex]

we can now divide both sides to isolate C: [tex]C = \frac{\frac{7}{12}}{H}[/tex], so now all we have to do is find how many hours passed.

From 10 P.M to 12 A.M, 2 hours pass. From 12 A.M to 7 A.M, 7 hours pass and from 7 A.M to 7:20 A.M, 20 minutes pass

So we have: [tex]2 \text{ hours} + 7 \text{ hours} + 20 \text{ minutes} = 9\text{ hours} + 20\text{ minutes}[/tex]

We want to represent this as one value and also in hours, so we'll need to convert the minutes to hours. To see how many 20 minutes is to one hour, we simply divide this 20 minutes by how many minutes are in an hour, which is 60 minutes: [tex]\frac{20}{60} = \frac{1}{3}[/tex]

It's actually super useful to keep this in fraction form, and even convert the 9 hours to fraction form: [tex]9 + \frac{1}{3} = \frac{27}{3} + \frac{1}{3} = \frac{28}{3}[/tex]

Now from here, we know that: [tex]H = \frac{28}{3}[/tex]

so let's plug this into the expression we made! [tex]C = \frac{\frac{7}{12}}{\frac{28}{3}}\implies \frac{7}{12} * \frac{3}{28}[/tex]

before multiplying, we can rewrite 12 as (4 * 3) so we can cancel out the 3 in the numerator and denominator making the simplification process a bit easier. We can also rewrite 28 as (4 * 7) to cancel out the 7 in the numerator and denominator: [tex]C = \frac{7 * 3}{(4 * 3) * (7 * 4)} = \frac{1}{16} = 0.0625[/tex]

This means if we multiplied the 1/16 or 0.0625 by the 9.33333 hours that passed we would get the total amount that decreased: 7/12

Let's substitute the given values into the equation, we'll have;

Let's subtract 1/25 from both sides of the equation;

Let's cross multiply;

First, let's draw the picture and write some information that we already know about it

Remember that a line that passes throw two parallel lines will make the same angles, so if we already know that the angle <3=135º (which is alpha in the draw) we can find the supplementary angle which is <4 (the angle that we want to know), lets do it:

Finally, the angle <4=45º

Assuming that these variables behave proportionally, we can solve this problem through proportional relationships:

Step-by-step explanation:

Given the data set (ages of grandparents):

52, 54, 57, 61, 56, 61, 67, 64, 63, 57, 60, 50

Let's create a five-number summary that represents the given data set and also create a box plot.

A) A five number summary of a data set consists of the following:

• Minimum value

• First quartile

• Median

• Third quartile

• Maximum value

Let's determine the five-number summary of the given data set.

• Minimum value:

The minimum value is the smallest number from the given data set.

Thus, the minimum is = 50

• First quartile:

The first quartile is also called the lower quartile. It is the median of the lower half of the data set.

To find the first quartile, list out the lower half of the data set after arranging the data in acsending order.

Arrange in ascending order: 50, 52, 54, 56, 57, 57, 60, 61, 61, 63, 64, 67

Lower half: 50, 52, 54, 56, 57, 57

Median of lower half:

Therefore, the first quartile is = 55

• Median:

Median is the middle term of the data set.

50, 52, 54, 56, 57, 57, 60, 61, 61, 63, 64, 67

The middle terms are = 57 and 60

To find the median, divide the sum of the middle terms by 2.

Thus, we have:

Therefore, the median of the data set is 58.5

• Third Quartile:

The third quartile is also called the upper quartile. It is the median of the upper half of the data set.

Upper half of data set = 60, 61, 61, 63, 64, 67

Median of upper half =

Therefore, the third quartile is 62

• Maximum value:

The maximum value is the greatest number in the given data set.

The greatest number in the data set is 67.

Therefore, the maximum value is 67.

We have the five-number summary that represents the data set below:

• Minimum = 50

• First quartile = 55

• Median = 58.5

• Third quartile = 62

• Maximum = 67

b) Let's create a box plot that represents the data set.

We have the box plot below:
