Answer:

Angle GBH:

Angle ECD: 34

Angle HGB: 20

Angle FGH:

Step-by-step explanation:

Find all of the angles, some are needed to find others. Use the given angles...

FEC is 124, so the other side of it, CED must be 180-124 which is 56

Now we know CED is 56 and CDE is 90, and a triangles angles add up to 180, therefore angle ECD is 180-56+90, which is 34

Now we can find HCE, 180-90+34, which is 56

Angle CBG is 70 because 180-110 is 70

You can find angle HGB by looking at angle BCG which is 90 and angle CBG which is 70 and subtracting them from 180. 180-90+70=20

Answer:

The answer is 72

Step-by-step explanation:

In order to resolve the expression, we have to know the factorial function.

The factorial function (with a symbol: !) says to multiply all whole numbers from our chosen number down to 1.

For example:

5!=5*4*3*2*1=120

When the exercise has a fraction with factorial functions, we usually try to simplify it, that is, we have to expand the factorial value until to get the same factorial value in the denominator or numerator:

5!/3!=[tex]\frac{5*4*3!}{3!} =5*4=20[/tex]

In this case:

9!/(9-2)!=9!/7!=[tex]\frac{9*8*7!}{7!} =9*8=72[/tex]

The final value is 72.

The value of the factorial 9!/(9-2)! is 72

To find the value of 9!/(9-2)!, we first need to evaluate the factorial expressions.

9! means the factorial of 9, which is calculated by multiplying all positive integers from 1 to 9:

9! = 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1

Similarly, (9-2)! means the factorial of (9-2), which simplifies to 7!:

7! = 7 x 6 x 5 x 4 x 3 x 2 x 1

Now, let's substitute the factorial expressions back into the original equation:

9!/(9-2)! = (9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1)/(7 x 6 x 5 x 4 x 3 x 2 x 1)

Now we can simplify the expression:

9!/(9-2)! = (9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1)/(7 x 6 x 5 x 4 x 3 x 2 x 1)

= 9 x 8

= 72

Therefore, the value of 9!/(9-2)! is 72.

Final answer:

The given relation is not a function because there are multiple output values for one input value.

Explanation:

The given relation, xy1−21−3213−2, is not a function. In order for a relation to be a function, each input value (x) must have only one corresponding output value (y).

Let's examine the relation:

x = 1, y = 2

x = 2, y = -3

x = 3, y = 2

As you can see, for x = 1, there are two different corresponding values of y (2 and -3). Therefore, the given relation is not a function.

Answer:

The equivalent expression is [tex]7^{6}[/tex] ⇒ answer A

Step-by-step explanation:

* Lets revise some rules of the exponents

- In the exponential functions we have some rules

# In multiplication if we have same base then add the power

  b^m  ×  b^n  =  b^(m + n)  

- Ex: [tex]5^{11}*5^{4}=5^{11+4}=5^{15}[/tex]

# In division if we have same base we subtract the power

  b^m  ÷  b^n =  b^(m – n)

- Ex: [tex]\frac{3^{10}}{3^{4}}=3^{10-4}=3^{6}[/tex]

* Now lets solve the problem

- There is the expression [tex]\frac{7^{13}}{7^{7}}[/tex]

- We have base 7 up and down

∵ In division if we have same base we subtract the power

∵ The base up is 7 and the base down is 7

- We will subtract the powers

∴ [tex]\frac{7^{13}}{7^{7}}=7^{13-7}=7^{6}[/tex]

∴ The answer is [tex]7^{6}[/tex]

The correct option is:

C. 18 inches.

To calculate the volume of a cylinder we need to use the formula:

[tex]Volume=\pi *radius^{2}*height[/tex]

We are given a cylinder that has a volume of 288 π cubic inches and we know that its radius is equal to 4 inches, so, to calculate the height of the cylinder, we need to isolate it from the equation of volume, so, isolating we have:

[tex]Volume=\pi radius^{2} height[/tex]

[tex]\frac{Volume}{\pi radius^{2} }=height[/tex]

Now, substituting the given information, we have:

[tex]height=\frac{288\pi in^{3}}{\pi (4in)^{2} }=\frac{288\pi in^{3}}{16\pi in^{2} }=18in[/tex]

Hence, we have that the correct answer is:

C. 18 inches.

Have a nice day!

Answer:

The correct answer is option c 18 inches

Step-by-step explanation:

Points to remember

Volume of cylinder =  πr²h

Where r - Radius of cylinder and

h - Height of cylinder

To find the height of cylinder

Here volume = 288π cubic inches and radius = 4 inches

Volume = πr²h

288π = π* 4² * h

288 = 16h

h = 288/16 = 18 inches

Therefore height of cylinder = 18 inches

The correct answer is option c 18 inches

Answer:

∠2 and ∠3 are complementary

Step-by-step explanation:

Complementary angles add up to 90°. Angles 1 and 3 are complementary, so the formula is ∠1 + ∠3 = 90°. Given that Angle 1 equals to angle 2, we substitute angle 2 for angle one in the equation stated before. Now we have ∠2 + ∠3 = 90°, so angles 2 and 3 are complementary

Answer:

±[tex]12[/tex]

Step-by-step explanation:

We need to find [tex]\sqrt{144}[/tex].

Now, we know that  [tex](12)^{2} = 144[/tex] and [tex](-12)^{2} = 144[/tex]

Therefore: [tex]\sqrt{144}=[/tex]±[tex]12[/tex]

Summarizing, the real square roots of 144 are ±[tex]12[/tex]

[tex]\sqrt{144}=\pm12[/tex]

[tex](g\cdot f)(x)=\dfrac{1}{x}-4[/tex]

[tex]D_{g(f(x))}:x\not =0[/tex]

No, since 0 doesn't belong to the domain.

[tex]\bf \textit{volume of a cone}\\\\ V=\cfrac{\pi r^2 h}{3}~~ \begin{cases} r=radius\\ h=height\\ \cline{1-1} r=12\\ h=45 \end{cases}\implies V=\cfrac{\pi (12)^2(45)}{3}\implies V=2160\pi[/tex]

Answer:

The length of side BC is 20.5 in

Step-by-step explanation:

we know that

In the right triangle ABC

The function cosine of angle of 35 degrees is equal to divide the adjacent side to angle of 35 degrees by the hypotenuse of the right triangle

so

cos(35°)=a/25

Solve for a

Multiply by 25 both sides

a=(25)*cos(35°)=20.5 in

therefore

The length of side BC is 20.5 in

The answer is:

The length of BC is equal to 20.5 inches.

Since we are working with a right triangle and we already know some of its dimensions, we can calculate the length of PC using the following equation:

[tex]Cos\alpha =\frac{a}{Hypotenuse}[/tex]

Where,

a is equal to BC

hypotenuse is equal to 25 inches.

alpha is equal to 35°

So, we will have the following equation and we can isolate "a" from it, so substituting we have:

[tex]Cos(35\°)=\frac{a}{25in}[/tex]

[tex]a=25in*Cos(35\°)=20.47inches[/tex]

Hence, the length of BC is equal to 20.5 inches (rounded to the nearest tenth)

Have a nice day!

For this case we have the following expression:

[tex](-4x) ^ 2 = 100[/tex]

To look for the solution:

 We apply root to both sides of the equation to eliminate the exponent:

[tex]-4x = \pm \sqrt {100}\\-4x = \pm10[/tex]

Then we have two solutions:

[tex]-4x = 10[/tex]

Dividing between -4 on both sides of the equation:

[tex]x = \frac {10} {- 4}\\x = - \frac {5} {2}[/tex]

The second solution:

[tex]-4x = -10[/tex]

Dividing between -4 on both sides of the equation:

[tex]x = \frac {-10} {- 4}\\x = \frac {5} {2}[/tex]

Answer:

[tex]x_ {1} = - \frac {5} {2}\\x_ {2} = \frac {5} {2}[/tex]

Answer:

See below in BOLD.

Step-by-step explanation:

What you need to do is identify the corresponding sides in the polygon than divide the larger length by the smaller.

3.  The side length 8 corresponds to the 4 in the other polygon.

So the scale factor  is 8/4 = 2.

4. Scale Factor = 24/20 = 1.2.

5. 40/32  = 5x / 24

5x = 40*24 / 32

5x = 30

x = 6.

6. 25/30 = 4x + 7 / 42

5/6 = 4x + 7 / 42

6(4x + 7) = 210

24x = 210 - 42 = 168

x = 168/24

x = 7.

7. 40/24 = 3x + 5 / 21

5/3 = (3x + 5) / 21

9x + 15 = 105

9x = 90

x = 10.

8.   24 / 40 = (x + 3) / 15

3/5 = (x + 3) / 15

5x + 15 = 45

5x = 30

x = 6.
