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:

14

Step-by-step explanation:

Knowing the first triangle is isosceles, and given the degree is 69.

We can find the top left angle as 180-69-69=42

42 combine with another angle to make a right angle

90-42=48.

The second triangle is also isosceles, so to find 2

we can use 180-42=138 (supplementary angles rule)

and given 10x-8=138

10x=140

x=14

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.

Answer:

✔️(20, 16)

✔️(15, 12) = 15 pounds of beans cost $12

Step-by-step explanation:

✔️20 pounds of beans is represented by the ordered pair, (20, 16). On the graph, when beans (x) = 20 pounds, cost (y) = $16.

✔️Also, the ordered pair (15, 12) means that 15 pounds of beans cost $12. From the graph, when beans (x) = 15 pounds, cost (y) = $12.

Answer:

[tex](c)\ \frac{6}{5}[/tex]

Step-by-step explanation:

The question is incomplete as it has missing options.

See attachment for complete question and options..

From the attachment, we have:

[tex](a)\ \frac{-7}{9}[/tex]

[tex](b)\ \frac{-8}{2}[/tex]

[tex](c)\ \frac{6}{5}[/tex]

[tex](d)\ \frac{3}{-2}[/tex]

All but 6/5 are negative numbers.

This is so because:

[tex](a)\ \frac{-7}{9}[/tex] has a negative sign at the numerator

[tex](b)\ \frac{-8}{2}[/tex] has a negative sign at the numerator

[tex](d)\ \frac{3}{-2}[/tex]  has a negative sign at the denominator

Only [tex](c)\ \frac{6}{5}[/tex] has positive integers at the numerator and denominator.

Linear is a straight line. You might have heard of Linear Function.

[tex]y = mx + b[/tex]

The equation above is slope-intercept form.

Exponential is both increasing graph and decreasing graph depending on the coefficient.

Exponential Equation

[tex]y = {a}^{x} \: \: \: (a > 0) \: \: (a \neq1)[/tex]

Exponential Graph increases when a-term is greater or equal to 1.

Exponential Graph decreases when a-term is greater than 0 but less than 1.

From the equation, it is exponential of x-term as an exponent. The equation matches with exponential form.

Answer:

(6, -1)

Step-by-step explanation:

The coordinates of the midpoint of a line is [(x₁ + x₂)/2, (y₁ + y₂)/2]. For the given line, JK where J = (-9, 5) = (x₁, y₁) and K = (21,-7) = (x₂, y₂).

So [(x₁ + x₂)/2, (y₁ + y₂)/2]

= [(-9 + 21)/2, (5 + (-7))/2]

= [12/2, (5 - 7)/2]

= [12/2, -2/2]

= (6, -1)

Answer:

4 thermoses of hot chocolate

The number of thermoses that Nelli makes with 3 cups of cocoa powder will be 2.

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

It is also known as the product. If the object n is given to m times then we just simply multiply them.

One thermos of hot chocolate uses 2/3 cup of cocoa powder.

Then the number of thermoses that Nelli makes with 3 cups of cocoa powder will be given by the multiplication of 2/3 and 3.

⇒ (2/3) x 3

⇒ 2

The number of thermoses that Nelli makes with 3 cups of cocoa powder will be 2.

The required expression is:

Please check the attached graph too.

Step-by-step explanation:

The slope-intercept form of the linear or line function

[tex]y = mx+b[/tex]

where

In our case,

The cost of hiring a taxi consists of a fixed cost of $3. It means the fixed cost of $3 is the initial condition.

Thus, the y-intercept b = 3

It is stated that the cost of per kilometer distance = $0.5

Thus, the rate of change or slope m = 0.5

As y represents the cost and x represents the number of kilometers.

so substituting m = 0.5 and b = 3 in the slope-intercept form of the linear or line function

y = mx+b

y = 0.5x + 3

Thus, the required expression is:

Answer:

300 ft long

Step-by-step explanation:

divide 1200 by 4 sense the beginners trail is one-fourth the length of the expert trail

The length of beginner trail is 300 meter long.

Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications. For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.

Given that;

The tape diagram models the lengths of two snowboarding trails.

And, The expert trail is 1200 meters long.

Now, The length of beginner trail is,

⇒ 1200 / 4 meter

⇒ 300 meter

Thus, We get;

⇒ The beginner trail is 300 meter long.

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:

16 ft²

Step-by-step explanation:

Since we're told that 2 ft diameter was cut of the board. We use the formula for hollow circle to find the area.

Area of remaining body = area of full body - area of removed body.

Area = πd²/4

Area of remaining body = (π * 5²)/4 - (π * 2²)/4

Area of remaining body = 19.64 - 3.142

Area of remaining body = 16.49 ft²

Therefore, the remaining area is then calculated into 16 ft²
