Answer:

a = 8√2

Step-by-step explanation:

a² + b² = c²

a² +14² = 18²

a² + 196 = 324

Subtract 196 from both side

a² = 128

Take the square root of both sides

a = √128

a = √(64 * 2)

a = 8√2

Answer:

b) 7x² - 12x√14 + 72

Step-by-step explanation:

Let's solve the problem,

→ (x√7 - 3√8)(x√7 - 3√8)

→ (x√7 - 3√8)²

→ 7x² - 12x√14 + 72

Hence, option (b) is correct.

Answer:

10m = height

Step-by-step explanation:

Volume of a Cylinder = πr²(h), where r is the radius and h is the heigh of the circle, therefore;

=> 1000π = π(10)²(h)

=> 1000π = 100π(h)

=> 1000π/100π = h

=> 10 = h

Hope this helps!

Answer:

12 and 10

Step-by-step explanation:

Answer:

11 and 21

Step-by-step explanation:

Let the first number equal x. If the first number, the second number is ten more, and can represented as x + 10. Now, the sum is 32, so we can add the two numbers to get 32:

x + x + 10 = 32

2x + 10 = 32

2x = 22

x = 11

If the first number 11, the second number is 10 more, and therefore is 21.

Answer:

104

Step-by-step explanation:

The angle is supplementary, so the total angle measure (of 79 and x) is 180. Just subtract the value we have (76) from the total value (180), and you get x.

Answer:

x = 7

Step-by-step explanation:

opposite sides are equal so we can set up this equation and solve for 'x':

3x-2 = 19

3x = 21

x = 7

Answer;

14x-12

Explanation:

Since we are not asked what to fine, we can find the perimeter of the rectangle

Perimeter = 2(L+W)

Perimeter = 2(2x+1+5x-7)

Perimeter = 2(7x - 6)

Perimeter = 14x - 12

Hence the perimeter of the rectangle is 14x-12

Answer:

B. The graph of his the graph of g vertically shifted up 1 unit.

Step-by-step explanation:

[tex]Given:-[/tex]

[tex]g(x)=x^2[/tex]

[tex]h(x)=g(x)+1[/tex]

[tex]so,h(x)=x^2+1[/tex]

[tex]f(x)=x^2[/tex]

Hey there! :)

Please keep in mind that SOH-CAH-TOA is a life saver when it comes to trig! Where:

- SOH = Sin: opposite over hypotenuse

- CAH = Cos: adjacent over hypotenuse

- TOA = Tan: opposite over adjacent

The question is asking us to find the value of x given the following located in the image provided.

Because we've been given 51°, we'll use this angle to determine whether we're using Sin, Cos, or Tan.

We must now look at the other given variables in this triangle - specifically where they are located.

While looking at our given angle (51°), we see that x is located on the opposite side of 51° while 8 is located adjacent (also known as next) to 51°.

Because of this, we now know that we'll be using Tan (opposite over adjacent) to find the value of x because our given values are opposite and adjacent to 51°.

We now set up our equation to find the value of x:

tan (51°) = [tex]\frac{x}{8}[/tex] ⇒ we set it up this way because x is opposite of 51° & 8 is adjacent to it.

Now, we must remove all fractions. We can do this by multiplying both sides by 8.

8 × tan (51°) = [tex]\frac{x}{8}[/tex] × 8

Now, we simplify.

8 × tan (51°) = x

Now, we plug this into our calculator. Make sure your calculator is in degrees mode since we are using degrees, not radians.

8 × 1.2348 = x

Simplify.

x = 9.9

Therefore, angle x is 9.9

Hope this helped! :)

Answer: Y = -3 and for x = 5

Step-by-step explanation:

You would get this because when you multiply 6 by 5 you get 30 then you multiply 11 by -3 and you get -33 then you add both and -3 then that’s how you find for the value y and can please mark brainly if you do thx and have a good day

Answer:

4√2

Step-by-step explanation:

√32 = √(16 * 2) = 4√2

Answer:

A. Wage=βo +β1, Female + u, where Female (=1 if female) is an indicator variable and u the error term.

Wage = dependent variable

FP = Independent variable.

Step-by-step explanation:

The model selected model shows the relationship between the wages earned by male and female gender based on earnings of the two gender groups.

Wage is the dependent variable while factors upong which their wage depends on will be adopted as the independent variable. Since gender is categorical and cannot be used in that form during regression analysis. The it can be converted into a dummy or encoded variable. Such as treating female as = 1.

Answer:

p ≈ 97 cm

a = 390 cm²

Step-by-step explanation:

First figure out the missing lengths

The triangle on the right is a standard 9 - 12 - 15 right triangle

The triangle in the left is a right isosceles triangle so the sides are both the same 12cm.  The hypotenuse is found using c² = a² + b² and is approx 17 cm

--------------------------

perimeter

p ≈ 12 + 22 + 9 + 15 + 22 + 17

p ≈ 97 cm

Area

a = left triangle + rectangle + right triangle

a = (1/2)(12*12)  + (12*22) + (1/2)(9*12)

a = 390 cm²

Answer:

Option D. 4√2

Step-by-step explanation:

8/√2

The above expression can be simplified as follow:

8/√2

Rationalise the denominator i.e multiply the numerator and the demoninator by √2. This is illustrated below:

8/√2 × (√2/√2)

8 × √2 / √2 × √2

8√2 / 2

4√2

Thus, option D gives the correct answer to the question.

Answer:

Nicholas pulls 5 blue marbles from the bag.

Step-by-step explanation:

Since Nicholas performs an experiment in which he pulls a marble from a bag, and in his experiment, he finds that he is twice as likely to pull a red marble as a blue marble, to determine, if Nicholas pulls 10 red marbles, how many blue marbles does he pull, the following calculation must be performed:

10/2 = X

5 = X

Therefore, Nicholas pulls 5 blue marbles from the bag.

Answer:

38

Step-by-step explanation:

In the standard direct variation equation, y = kx, k is the constant of proportionality.

Since the equation is y = 38x, it is in the direct variation form.

Using this, 38 is the k value, since it is the coefficient of x.

So, the constant of proportionality (k) is 38.
