Answer:

B = 34.2°

C = 58.2° or 121.8°

c= 10.6

Step-by-step explanation:

Step 1

Finding c

We calculate c using Pythagoras Theorem

c²= a² + b²

c = √a² + b²

a= 8, b = 7

c = √8² + 7²

c = √64 + 49

c = √(113)

c = 10.630145813

Approximately c = 10.6

Step 2

Find B

We solve this using Sine rule

a/sin A = b/sin B

A = 40°

a = 8

b = 7

Hence,

8/sin 40° = 7/sin B

8 × sin B = sin 40° × 7

sin B = sin 40° × 7/8

B = arc sin (sin 40° × 7/8)

B ≈34.22465°

Approximately = 34.2°

Step 3

We find C

Find B

We solve this using Sine rule

b/sin B = c/sin C

B = 34.2°

b = 7

c = 10.6

C = ?

Hence,

7/sin 34.2° = 10.6/sin C

7 × sin C = sin 34.2 × 10.6

sin C = sin 34.2° × 10.6/7

C = arc sin (sin 34.2° × 10.6/7)

C = arcsin(0.85)

C= 58.211669383

Approximately C = 58.2°

Or = 180 - 58.2

C = 121.8°

Answer:

C=105.8 degrees. c=12

Answer:

0<x<5

Step-by-step explanation:

I assume based on the question that you are in a geometry class, so you should understand this. Based on the triangle inequality theorem, the sum of two sides of a triangle are greater than the third side. Using this, we can say that x+3+3 should be greater than 5. since 3+3 is already six regardless of what x is, we know that as long as x is greater than 0 it meets this requirement. Also, if 5 and 3 are added they should be greater. 5+3=8, so x must be less than 5 for the 5 and 3 sides to be greater.

Answer: 18080!

Step-by-step explanation:400 x 450

1. Multiplying from the oneths place ( turning 45.2 into 450)

      2x0=0  2x0=0  2x4=8 = So the first answer is 800

2. Multiply from the tenths place

5 x 0 = 0   5 x 0 = 0   5 x 4 = 20 = the second answer is 2000

Multiplying the hundredths place

4 x 0 = 0  4 x 0 = 0   4 x 4 = 16  = The third answer is 1600

800 + 2000 + 1600 = 18080    Hope this helped! :)

-7x^3+8x^2+x-5

Step-by-step explanation:

We are simply adding the two functions:

f(x) + g(x) = (2x^2-5x^3+x-7) + (6x^2-2x^3+2) = 8x^2-7x^3+x-5 = -7x^3+8x^2+x-5

Answer:

40people

Step-by-step explanation:

Let the number of those that owned a dog be x

Let the number of those that owned a cat be y

If the number of people who own a dog is four times the number of people who own a cat, then:

x = 4y

Since x+y =100

4y+y = 100

5y = 200

y = 200/5

y = 40

x = 4(40)

x = 160

Hence 40 people surveyed own a cat

Answer:

To plot an inequality, such as x>3, on a number line, first draw a circle over the number (e.g., 3). Then if the sign includes equal to (≥ or ≤), fill in the circle. If the sign does not include equal to (> or <), leave the circle unfilled in.

Answer:

The inverse of function [tex]f(x)= (x+7)^5[/tex] is [tex]\mathbf{f^{-1} (x)=\sqrt[5]{x}+7}[/tex]

Option A is correct option.

Step-by-step explanation:

For the function [tex]f(x)= (x+7)^5[/tex], Find [tex]f^{-1} (x)[/tex]

For finding inverse of x,

First let:

[tex]y=(x+7)^5[/tex]

Now replace x with y and y with x

[tex]x=(y+7)^5[/tex]

Now, solve for y

Taking 5th square root on both sides

[tex]\sqrt[5]{x}=\sqrt[5]{(y+7)^5}\\\sqrt[5]{x}=y+7\\=> y+7=\sqrt[5]{x}\\y=\sqrt[5]{x}-7[/tex]

Now, replace y with [tex]f^{-1} (x)[/tex]

[tex]f^{-1} (x)=\sqrt[5]{x}+7[/tex]

So, the inverse of function [tex]f(x)= (x+7)^5[/tex] is [tex]\mathbf{f^{-1} (x)=\sqrt[5]{x}+7}[/tex]

Option A is correct option.

Given :

A crafter is making a triangular flag.

She has two sides of length 24 inches and 36 inches.

To Find :

The length possibilities (in whole inches) for the third side.

Solution :

We know, the sum of two sides of any triangle is always greater than the length of the third side.

Let, third side is d.

So, d is always less than the sum of other sides i.e. ( 24 + 36 ) = 60 .

d < 60

Also, difference between the difference of length is always less than the side.

So, d > 36 - 24

d > 12

Therefore, the length possibilities for the third side is between 13 inches and 59 inches.

Answer:

x = 4

Step-by-step explanation:

(10x + 9) + 34 + 97 = 180

10x +140 = 180

10x = 40

x = 4

The value of x in the given angles of the traingle CAB for angle m∠A is determined as 4.

The sum of angles in a triangle can be used to determine the value of x in the given angles above.

m∠A + m∠B + m∠C  = 180 (sum of angles in a triangle)

10x + 9 + 34 + 97 = 180

10x + 140 = 180

10x = 40

divide both sides by 10;

x = 40/10

x = 4

Thus, the value of x in the given angles of the traingle CAB for angle m∠A is determined as 4.

Answer: -4 and 4

Step-by-step explanation:

In mathematics, the Pythagorean theorem, or Pythagoras's theorem, is a fundamental relation in Euclidean geometry among the three sides of a right triangle. It states that the area of the square whose side is the hypotenuse (the side opposite the right angle) is equal to the sum of the areas of the squares on the other two sides.

Answer:

Number of game lose = 29 games (Approx)

Step-by-step explanation:

Given:

Winning part = 5/12

Total game = 49

Find:

Number of game lose

Computation:

Lose part = 1 - 5/12

Lose part = 7/12

Number of game lose = Total game x Lose part

Number of game lose = 49 x [7/12]

Number of game lose = 28.58

Number of game lose = 29 games (Approx)

They would lose 29 games if they play 49 games

They won 5 out of their first 12 games.

Hence the number of game lost in their first 12 games = 12 - 5 = 7  games

The rate at which they lose = 7 games / 12 games

Given that they played 49 games, hence:

Number of games lost = (7 games / 12 games) * 49 = 28.58

They would lose 29 games if they play 49 games

4.99 + 1.99m = T. Dependent Variable = T (Total Cost), Independent Variable = M (Movies) Now, for the equation we have to input 5 for the m because he watched 5 movies. So, 4.99 + 1.99(5) = T Well, 1.99 x 5 is 9.95 so our next step is this 4.99 + 9.95 = T and that  added up together would be 14.94 dollars. $14.94 = T
