17. Find the value of x and y. PLEASE HELPPP!!!!

Answer:  (1a) 250°  (1b) 70°    (2) see below

Step-by-step explanation:

1a) -110 + 360 (one rotation clockwise) = 250°

1b) 430 - 360 (one rotation counterclockwise) = 70°

2) sec Ф = -8/5    in Quadrant III

Quadrant III identifies that both sin (y) and cos (x) are negative.

sec = r/x --> r = 8, x = -5, and y = -√39

(Use Pythagorean Theorem x² + y² = r² to solve for y)

[tex]\sin\theta=\dfrac{y}{r}=\dfrac{-\sqrt{39}}{8}[/tex]              [tex]\csc\theta=\dfrac{r}{y}=\dfrac{-8}{\sqrt{39}}[/tex]  rationalized = [tex]\dfrac{-8\sqrt{39}}{39}[/tex]

[tex]\cos\theta=\dfrac{x}{r}=\dfrac{-5}{8}[/tex]                  [tex]\sec\theta=\dfrac{r}{x}=\dfrac{-8}{5}[/tex]  (GIVEN)

[tex]\tan\theta=\dfrac{y}{x}=\dfrac{\sqrt{39}}{5}[/tex]              [tex]\cot\theta=\dfrac{x}{y}=\dfrac{-5}{-\sqrt{39}}[/tex]  rationalized = [tex]=\dfrac{5\sqrt{39}}{39}[/tex]

NOTE THAT YOU ARE ALLOWED A MAXIMUM OF 3 QUESTIONS PER POST.  Please repost #3 and #4 as a different question and I will answer them.

The quotient of 100/20 is 5. The correct option is F.

The division in mathematics is one kind of operation. In this process, we split the expressions or numbers into the same number of parts.

We have the expression:

100/20

To find the quotient:

Quotient: The number resulting from the division of one number by another.

Use division operation.

100 / 20

Simplifying,

10x10 / 2 x 10

Factor out 10.

We get,

10/2

So, 10/2 = 5

Therefore, the quotient is 5.

Answer:

x + 5y = 0

Step-by-step explanation:

y = mx + b

y = -1/5 x + b

1 = -1/5 (-5) + b

1 = 1 + b

b = 0

y = -1/5 x

5y = -x

x + 5y = 0

The English translation of the question is

A reservoir was full at the end of May. In the month of June 3/10 of its reserves were consumed and at the end of July only half remained. What fraction of the reservoir was consumed during the month of July?

Answer:

1/5 of the Reservoir will be consumed in the month of July.    

Step-by-step explanation:

We are given

Full reservoir at the end of month May. In the month of June 3/10 of the reservoir was consumed.

Amount present in the Reservoir at the end of the month June will be = 1 -3/10

                                                                                                          = 7/10

Now this 7/10 of the Reservoir will be used for the next month which is July

It is given that at the end of July only 1/2 of the Reservoir is remained that means the amount that was left at the end of the Month June will be used for the month July. So the amount consumed in the month of July will be

    Amount consumed  =  7/10 - 1/2

                                     = 2/10 = 1/5

Therefore 1/5 of the reservoir will be consumed in the month of July.

Answer:

Add  7  to both sides of the equation

3 − 7 + 7 = 8 + 7

Simplify

3m = 8 + 7

3 = 1 5

Divide both sides of the equation by the same term

3 = 1 5

3 / 3  =  1 5 /3

Answer:

30

Step-by-step explanation:

The / is another symbol for multipation. Just multiply 3 with 4 and 5. Then multiple 2 and 3 and 5, then you subtract 3 times 4 times 5's answer by 2 times 3 times 5's answer. You will get 30 as the final answer

Answer:

In exact form the answer is 1/6 Or in decimal form it would be 1.2, in mixed number form it would be 1 and 1/5

So 3+{2×(8-4+6)}-5-{9+4-[3×(1-5)]}​

3+20-5-9+4-3(1-5)

Step 2

3+20-5-9+4-3(1-5)  Simplify

Step 3

18-9+4-3(1-5)

Answer:

x = [tex]\frac{9}{4}[/tex]

Step-by-step explanation:

Given

[tex]\frac{4x}{x+1}[/tex] - [tex]\frac{5}{x}[/tex] = [tex]\frac{4}{x^2+x}[/tex] ← factor denominator

[tex]\frac{4x}{x+1}[/tex] - [tex]\frac{5}{x}[/tex] = [tex]\frac{4}{x(x+1)}[/tex]

[ x ≠ 0, x ≠ - 1 as these would make the terms undefined ]

Multiply through by x(x + 1)

4x² - 5(x + 1) = 4

4x² - 5x - 4 = 4 ( subtract 4 from both sides )

4x² - 5x - 9 = 0 ← in standard form

(x + 1)(4x - 9) = 0 ← in factored form

Equate each factor to zero and solve for x

x + 1 = 0 ⇒ x = - 1

4x - 9 = 0 ⇒ 4x = 9 ⇒ x = [tex]\frac{9}{4}[/tex]

However, x ≠ - 1 for reason given above, then

solution is x = [tex]\frac{9}{4}[/tex]

Answer:

The distance from the ball to the left post is 50 feet.

Step-by-step explanation:

Since a soccer goal is composed of a pair of 8 ft upright posts, positioned 48ft apart with a horizontal crossbar and netting boxing in the goal, and a soccer ball is positioned directly in front of the right goal post at a distance of 14ft, to To determine what is the ground distance from the ball to the left goal post, the Pythagorean theorem must be applied through the following calculation:

A ^ 2 = B ^ 2 + C ^ 2

A ^ 2 = 14 ^ 2 + 48 ^ 2

A ^ 2 = 196 + 2,304

A = √2500

A = 50

Thus, the distance from the ball to the left post is 50 feet.
