What is the domain of the function y=3 squared root of x -1 ?
O-o -1 O 0 1

Answers

Answer 1

[tex]y=3\sqrt{x-1}[/tex]

The domain is x ≥ 1 as x cannot be less than 1 or else it'll become negative in square root which you cannot find a value.

The sum of two numbers is 59. The larger number is 7 more than the smaller number. What are the numbers?

Answers

Answer:

26 and 33

Step-by-step explanation:

7+a+a=59

7+2a=59

2a=59-7

2a=52

a=52÷2

a=26

The bigger number is 7 more bigger therefore

26+7= 33

You measure 22 watermelons' weights, and find they have a mean weight of 36 ounces. Assume the population standard deviation is 6.9 ounces. Based on this, construct a 95% confidence interval for the true population mean watermelon weight. Give your answers as decimals, to two places

Answers

Answer:

Step-by-step explanation:

Confidence interval formula is expressed as;

CI = xbar ±(z*s/√n)

xbar is the mean = 36

z is the z score at 95% CI = 1.96

s is the standard deviation = 6.9

n is the sample size = 22

Substitute

CI = 36  ±(1.96*6.9/√22)

CI = 36  ±(1.96*6.9/4.6904)

CI = 36  ±(1.96*1.4711)

CI = 36  ± 2.8833

CI = (36 - 2.8833, 36 + 2.8833)

CI = (33.1167, 38.8833)

Hence the 95% CI for the true population mean is 33.12<x<38.88

Clancy has 4 2/3 cups of yogurt to share with his friends at a party. Each guest will receive 1 serving of yogurt which is 3/4 of a cup.

Write a multiplication equation to determine the number of people, p, who can be invited to the party.

Answers

Answer:

4 2/3 divided by 3/4 = p

Step-by-step explanation:

whatever the answer to the equation is the amount of people able to be invited

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

The multiplication equation to determine the number of people, p, who can be invited to the party is 3/4 p = [tex]4\frac{2}{3}[/tex].

The number of people that can be invited to the party is 6 people.

What is an equation?

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example: 2x + 6 = 7 is an equation.

We have,

Amount of cups of yogurt Clancy have = [tex]4\frac{2}{3}[/tex]

Amount of cups of yogurt each person received = 3/4 of a cup

The number of people p that can be invited to the party:

3/4 p = [tex]4\frac{2}{3}[/tex]

3/4 p = 14/3

p = 14/3 x 4/3

p = 56/9

p = 6.22

p = 6

Thus,

The multiplication equation to determine the number of people, p, who can be invited to the party is 3/4 p = [tex]4\frac{2}{3}[/tex].

The number of people that can be invited to the party is 6 people.

Find the length of the missing side. The triangle is not drawn to scale.

Answers

Answer:

c = 10

Step-by-step explanation:

To find the hypotenuse of the triangle you would do the value of leg^2 + leg^2 to find the hypotenuse. Or you can look at it like a^2 + b^2 = c^2. But in order to get the value you would have to find the scare root of c^2.

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

In this case though we are doing 6^2 + 8^2 which equals 100. After calculating that we know c^2 power equals 100. So know you have to find the actual value of c by itself to get your hypotenuse. So we would find the square root of 100 which is 10. Hope this helps!!

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

Important words

Hypotenuse - In geometry, a hypotenuse is the longest side of a right-angled triangle, the side opposite the right angle.

Cathetus (legs of triangle) - Either of the sides that are adjacent to the right angle.

Use two formulas for volume to find the volume of the figure. Express the answer in terms of x and then round to nearest whole number.

Answers

Answer:

Volume of the figure = 341.3π + 1,280π = 1,621.33π

Volume of the figure to the nearest whole number = 1,621π m³

Step-by-step explanation:

The figure shown is composed of a hemisphere and a cylinder.

The volume of the figure = volume of hemisphere + volume of cylinder

Volume of the hemisphere = ⅔πr³

Radius (r) of hemisphere = 16/2 = 8 m

Volume of hemisphere = ⅔*π*8³ = ⅔*π*512 = 341.33π m³

Volume of Cylinder = πr²h

radius (r) = 16/2 = 8 m

height (h) = 20 m

Volume of cylinder = π*8²*20 = 1,280π m³

Volume of the figure = 341.3π + 1,280π = 1,621.33π

Volume of the figure to the nearest whole number = 1,621π m³

You need to make at least 360 wraps for a party. You can make 9 wraps per minute.

How long will it take you to make the number of wraps you need?
In two or more complete sentences write and solve an inequality for the situation and explain how you will solve the inequality.

Answers

Answer:

40 minutes

Step-by-step explanation:

What the person above/below me is saying, is you have to divide 360 and 9, to find x! X=40, 360/9=40! That's what they mean. I hope this helped you understand their answer!

It will take 40 minutes for me to make the 360 wraps that I need.

9x ≥ 360 ⇒ x ≥ 40

Step-by-step explanation:

I have to make at least 360 wraps for a party.

I can make 9 wraps per minute.

So, it will take minutes for me to make the 360 wraps that I need.

If I work for x minutes to make wraps, then I will be able to make 9x wraps.

So, the inequality that models the given condition is

9x ≥ 360

⇒ x ≥ 40 {Dividing both sides by 9}

Therefore, I need to work at least 40 minutes to reach my goal. (Answer)

We are given the equation:

√(4x - 2) + 3 = 5

Subtracting by 3 on both sides

√(4x - 2) = 2

Squaring both sides

4x - 2 = 4

Adding 2 on both sides

4x = 6

x = 3/2

Step-by-step explanation:

Hey there!

Given;

[tex] \sqrt{4x - 2} + 3 = 5[/tex]

Shift "3" on right side.

[tex] \sqrt{4x - 2} = 5 - 3[/tex]

[tex] \sqrt{4x - 2} = 2[/tex]

Squaring on both sides.

[tex] {( \sqrt{4x - 2} )}^{2} = {2}^{2} [/tex]

Simplify it.

[tex]4x - 2 = 4[/tex]

[tex]4x = 4 + 2[/tex]

[tex]x = \frac{6}{4} [/tex]

[tex]x = \frac{3}{2} [/tex]

Therefore, X = 3/2.

What is consumer price index?

The tool used to gauge inflation is the consumer price index (CPI). It is used to calculate the typical difference in pricing of household goods between two specified periods. It is an overall assessment of product pricing trends while maintaining quality.

The consumer price index is the new cost of market basket in terms of percentage of old cost of market basket.

CPI = consumer price index in current period

[tex]C_t[/tex]  = cost of market basket in current period

[tex]C_0[/tex]  = cost of market basket in base period

Then, we have:

CPI = [tex]C_t[/tex] / [tex]C_0[/tex] x 100

So, 186 = [tex]C_t[/tex] / 41.4 x 100

[tex]C_t[/tex] = $77
