Answer 1

Answer:

Hope it helps u

Step-by-step explanation:

When rotating a point 270 degrees counterclockwise about the origin our point A(x, y) becomes A'(y,-x). This means, we switch x and y and make x negative,

hence A(2,1) so after 270 degree counter clockwise rotation the A become,

A(1, -2)

ABC is a right triangle. If AC=4 and BC=10, find AB. Leave your answer is the simplest radical form.

Answers

Answer:

√116 or √84

Step-by-step explanation:

ABC is a right triangle

AC=4, BC=10, AB = ?

Here we have two options:

1. AB is hypotenuse, then:

AB = [tex]\sqrt{AC^2 + BC^2} = \sqrt{4^2 + 10^2} = \sqrt{16 + 100} =\sqrt{116}[/tex]

2. BC is hypotenuse and AB is the second leg, then:

AB = [tex]\sqrt{BC^2 - AC^2} = \sqrt{10^2 - 4^2} = \sqrt{100 - 16} = \sqrt{84}[/tex]

Kathy has a job on a farm.
. She earns $3.20 every 15 minutes she picks
green peppers.
. She earns $3.00 every 20 minutes she picks
carrots.
She picked green peppers for 45 minutes and
then spent an hour picking carrots.
How much money did Kathy earned? (write
your answer in dollars. cents)

Answers

$18.60
She picked peppers for 45 minutes and earned 3.20 every 15 so 3.20 * 3 is 9.60 then picked carrots for 60 minutes and earned 3 every 20 so 3*3 is 9 add them together it’s 18.60

Answers

Answer: Part A. B origin Part B. C(0,0)

Step-by-step explanation:

In a coordinate plane, there are two axes

1) x-axis which is the horizontal axis.

2) y-axis which is the vertical axis.

The intersection of both the axes is known as the origin whose coordiantes are (0,0), i.e. at this point value of x =0 and value of y =0.

Part A: The ordered pair that represents the intersection of the x-axis and y-axis is called the origin.

Part B: The coordinate. Part B the coordinates of the origin are (0,0).

Do NOT round your answer.

Answers

Answer:

the surface area is 3140 square feet

Step-by-step explanation:

The computation of the surface area is given below:

Given that

Diameter = 20 feet

radius = 20 ÷ 2 = 10 feet

Surface area = [tex]2\pi r^2 + 2\pi rh[/tex]

= 2 × 3.14 × (10)^2 + 2 × 3.14 × 10 × 40

= 6.28 × 100 + 6.28 × 400

= 628 + 25.12 × 100

= 628+ 2512

= 3140 square feet

hence, the surface area is 3140 square feet

The domain of a quadratic is all real numbers.
a) True
b) False

Answers

A) True

The domain of a quadratic function in standard form is always all real numbers, meaning you can substitute any real number for x. The range of a function is the set of all real values of y that you can get by plugging real numbers into x.

Answer:

Step-by-step explanation:

I'd be very hesitant to say true.

If the quadratic is in the form of y = x^2 then the statement is correct. The entire family all have a domain of all the real numbers.

However if the quadratic is of the form x=y^2 then the starting point of this quadratic is (0,0). All of these quadratics have a different starting point. \\

Since you have not specified the kind of quadratic, the answer is not always true.

A student said that x = 4 was not a solution to the question 3(x -6) = -8
Here is their work:
3(x -6) = -8
3 (4 -6) = -8
12 -6 = -8
6≠ -8
so x = 4 is not a solution

Did the student substitute x=4 correctly? How do you know?

Did the student simplify with Order of Operations correctly? How do you know?

If you try the problem, what do you get when you substitute x=4 into the equation?

Answers

Answer:

Step-by-step explanation:

3 (4 -6) = -8 is correct. The next step is to combine 4 and -6, obtaining

3(-2)

and this 3(-2) should equal -6, which is not the same as -8.

3(4 - 6) = 12 - 18, which differs from the student's solution. This is the reason for the wrong answer.

-2x + 8 = y
3x - y = 22

How do I solve it

Answers

answer

x=6, y=-2

explanation

-2x + 8 = y -------equ 1

3x - y = 22 -------equ 2

u can use any of the simultaneous equation method

using elimination method

rearrange first from -------equ 1

-2x+8=y

-y-2x=-8

multiple through by -1

y+2x=8 -------equ 3

rearrange first from -------equ 2

3x-y=22

-y+3=22 ------equ 4

equate 3 and 4, adding them together

y+2x=8 -------equ 3

-y+3=22 ------equ 4

0+5x=30

5x=30

x=6------equ 5

replace 6 for x in any equation

using -------equ 3

y+2x=8

y+2(5)=8

y+10=8

y=8-10

y=-2

Answer:

(x, y)=(6, -4)

Step-by-step explanation:

-2x+8=y

3x-y=22

Substitute the given value of y into the equation 3x-y=22

3x-(-2x=8)=22

Solve the equation for x

x=6

Substitute the given value of x into the equation 3x-y=22

3x6-y=22

Solve the equation for y

y=-4

The possible solution of the system is the ordered pair (x, y)

(x, y)=(6, -4)

Check if the given ordered pair is the solution of the system of equations

-2x6+8=-4

3x6-(-4)=22

Simplify the equalities

-4=-4

22=22

Since all of the equalities are true, the ordered pair is the solution of the system

(x, y)=(6, -4)

Hummingbirds have unusually large hearts for their body size. If a person's heart were as

big as a hummingbird's, his or her heart would weigh as much as a large dog.

Information you will need:

An average hummingbird weighs 0.3524 ounces and has a heart that weighs 0.00875

ounces.

1 pound = 16 ounces

The average weight of a large dog is usually more than 80 pounds.

Leo weighs 192 pounds.

a.) How much would Leo's heart weigh if it were the same ratio as a hummingbird's?

Show your work on your paper.

b.) is the original claim true or false? Justify your reasoning here along with your answer.

Answers

Answer: 4.8lbs, This claim is false

Step-by-step explanation:

Leo weighs 192 pounds. Then Leo's heart weight will be 76.258 ounces. So, its claim is false.

What are ratio and proportion?

A ratio is a group of sequentially ordered numbers a and b expressed as a/b, where b is never equal to zero. When two objects are equal, a statement is said to be proportional.

Hummingbirds have abnormally huge hearts for their body size. In the event that an individual's heart was essentially as large as a hummingbird's, their heart would weigh as much as an enormous canine's. A typical hummingbird weighs 0.3524 ounces and has a heart that weighs 0.00875 ounces.

The ratio of heart to weight is given as,

Ratio = 0.00875 / 0.3524

Ratio = 0.024829

The average weight of a large dog is usually more than 80 pounds. Leo weighs 192 pounds. Then Leo's heart weight is calculated as,

⇒ 0.024829 x 192 x 16

⇒ 76.28 ounces

Their heart weight of Leo is less than the weight of the dog. So, its claim is false.

More about the ratio and the proportion link is given below.
