Answer:

8 , 5 , 5.785

Step-by-step explanation:

y^2 - x^3

first just plug in the numbers and you get

(4)^2 - (2)^3

Multiply

16-8 and this equals 8

x1 + x^3 - y^2

same pattern plug in the numbers

(3)^(1) + (3)^3 - (5)^2

multiply

3 + 27 - 25

P

E

M

D

Addition

Subtraction so do 3+27 first and you get

30 - 25 = 5

x^4 / x^3 plug it in

(6)^4 / (6)^3

multiply

1269  / 216  

divide this and you get

Answer:

(u o w) (7) =  22

(w o u) 7) = 8

Step-by-step explanation:

We are given:

[tex]u(x)= x^2+6\\w(x)= \sqrt{x+9}[/tex]

We need to find:

a) (u o w) (7)

First we will find (u o w) (x) and then we will find (u o w) (7)

We know that (u o w) (x) = u(w(x))

Put value of w(x) into u(x)

we have:

[tex]u(x)=x^2+6\\Put\: x =\sqrt{x+9}\\u(w(x))=(\sqrt{x+9})^2+6\\u(w(x))=x+9+6\\ u(w(x))=x+15[/tex]

Now finding (u o w) (7)

We know that: (u o w) (7) = u(w(7))

[tex]u(w(x))=x+15\\Put\:x=7\\u(w(7))=7+15\\u(w(7))=22[/tex]

So, (u o w) (7) = 22

b) (w o u) (7)

First we will find (w o u) (x) and then we will find (w o u) (7)

We know that (w o u) (x) = w(u(x))

Put value of u(x) into w(x)

we have:

[tex]w(x)= \sqrt{x+9}\\Put\:x=x^2+6\\w(u(x))= \sqrt{(x^2+6)+9}\\w(u(x))= \sqrt{x^2+6+9}\\w(u(x))= \sqrt{x^2+15}[/tex]

Now finding (w o u) (7)

We know that (w o u) (7) = w(u(7))

[tex]w(u(x))= \sqrt{x^2+15}\\Put\:x=7\\w(u(7))= \sqrt{(7)^2+15}\\w(u(7))= \sqrt{49+15}\\w(u(7))= \sqrt{64}\\w(u(7))= 8[/tex]

So, (w o u) (7) = 8

Answer:

$7.60

Step-by-step explanation:

24% of $10 is $2.40

$10-$2.40=$7.60

Answer:

The answer is $7.60.

Step-by-step explanation:

The original price is 10 dollars. 24 percent of 10 dollars is $2.40. So, subtract that from 10 dollars to get the answer.

$10.00 - $2.40 = $7.60.

Hope this helps! Have a good day. :)

Answer:

153.86 units²

Step-by-step explanation:

From the question given above, the following data were obtained:

Pi (π) = 3.14

Radius (r) = 7 units

Area (A) =?

The area of a circle can be obtained by using the following formula:

A = πr²

A = 3.14 × 7²

A = 3.14 × 49

A = 153.86 units²

Thus, the area of the circle is 153.86 units²

LAW=WKL

By rule: ASA|SAA

Step-by-step explanation

don't know how to explain it

The triangle LAW ≅ WKL by ASA congruence property.

If corresponding two angles and one corresponding side of two triangles are of same measurement, then the considered pair of triangles are congruent.

We have to complete each congruence statement and name the rule used if cannot show the triangles are congruent from the given information leave the triangles name blank .

The triangle LAW ≅ WKL by ASA congruence

WL = WL (COMMON SIDE)

∠ALW = ∠KWL

∠AWL = ∠KLW

Also, These statements can be noted from the image.

Therefore, The triangle LAW ≅ WKL by ASA congruence property.

Answer:

I think the answer will be y=3/5x-3

Answer:

y = 3/5x - 3

Step-by-step explanation:

Slope-intercept form is y = mx + b.

For this question, all you need to do is move some stuff around!

In slope intercept form, the x is on the right side, so you would first subtract x from both sides.

3x - 5y = 15

Next, you would divide both sides of the equation by -5 to get y by itself.

-5y = 15 - 3x

Finally, rearrange the equation. y = mx + b

y = -3 + 3/5x

y = 3/5x - 3

There are 253 girls in a school.

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

Given that;

A school has 575 pupils.

And, There are 56% of the pupils are boys.

Here, 56% of the pupils are boys.

Hence, Percent of the girls = 100% - 56%

                                          = 44%

Since, A school has 575 pupils.

Hence, Number of girls = 44% of 575

                                     = 44/100 × 575

                                     = 253

Answer:

the answer is A. 36

Step-by-step explanation:

because the rectangles are proportionate, I set up ratios.

90:75 so h:30

from there I did 70/30 because those sides are proportionate to each other and this got me 2.5. then I did 90/2.5 to get 36

Answer:

They will meet in 7 hours.

Step-by-step explanation:

They are traveling toward each other, which means that their relative speed is the sum of their speeds.

Bill travels 20 mph and Michael travels 14 mph

This means that their relative speed is of 20 + 14 = 34 mph, that is, they get 34 miles closer each hour.

Michael and Bill are 238 miles apart, how long until they meet?

Each hour, they will be 34 miles closer. How many hours for 238 miles?

1h - 34 miles

x h - 238 miles

By rule of three

[tex]34x = 238[/tex]

[tex]x = \frac{238}{34} = 7[/tex]

They will meet in 7 hours.

Answer:

The inverse of a given function

d) [tex]g(x) = \frac{1}{4} x - 3[/tex]

Step-by-step explanation:

Explanation:-

Given that f(x) = 4x + 12

  let y = 4 x + 12

     4 x = y - 12

        [tex]x = \frac{y-12}{4}[/tex]

        [tex]x = \frac{1}{4} y - 3[/tex]      

we know that   y = f(x)

                   ⇒  x = f⁻¹(y)

      [tex](f^{-1} y) = \frac{1}{4} y - 3[/tex]

Put  replace 'y' in 'x'

    [tex](f^{-1} x) = \frac{1}{4} x - 3[/tex]

Final answer:-

The inverse of a given function

[tex]g(x) = \frac{1}{4} x - 3[/tex]

The answer is below

Step-by-step explanation:

Prove ∠RQS = ∠RTS

Two triangles are said to be congruent if all the three sides and three angles of one triangle is equal to the three sides and three angles of another triangle.

Statement                            Reason

QS ≅ TS                               Given

RS ≅ RS                               Reflexive property of congruence.      

R is the midpoint of QT       Given

QR = RT                                R is the midpoint of QT. Therefore by

                                             definition, QR = RT.

ΔRQS = ΔRTS                       Side-side-side triangle congruence theorem. If

                                             three sides of one triangle is equal to three

                                             sides of another triangle, then both triangles

                                             are congruent to each other.

∠RQS = ∠RTS                        Corresponding angles of congruent triangles

                                              are equal.

Answer:

The slope is 55.

Step-by-step explanation:

Slope determines the direction and the rate of increase or decrease between the two points on a surface or line.

In the question, it is given initially she is 20 miles north of her house

⇒ When x = 0 the y-coordinate is 20

So, the y-intercept is 20

Now, it is given that the rate of change is 55 miles per hour

Hence, the slope is same as 55 because it is the actual rate of change between the positions of Jennifer with time.

I believe it $6.67

Not sure, sorry!

Step-by-step explanation:

-- there is an equation to find this: (2n + 1) + (2n + 3) = (whatever number is given as their sum)

use the equation: 2n + 1 is an odd interger, 2n + 3 is the next odd integer.

(2n + 1) + (2n + 3) = 88

add like terms.

4n + 4 = 88

4n = 84

n = 21

now plugin.

2(21) + 1

42 + 1

= 43 (the first odd integer)

this means the second one would be 45.
