[tex](1+sin^{2} )cosx+(1+cos^{2} x)sinx=1=sin2x[/tex]

Answers

Answer 1

The answer is = 1 + sin x

Explanation

we need

a^2 - b^2 = (a+b) (a-b)

we use

cos^2 x + sin^2 x = 1

cos^2 x = 1 - sin^2 x = ( 1 + sin x) ( 1 - sin x )

therefore

cos ^2 x over 1 - sin x = 1+ sin x

Find the unknown sizes of angles:

Answers

First we find X:
3x+x=180
4x=180
x=180/4
x=45.

3x=135

135+y=180
y=180-135
y=45

45+z=180
z=180-45
z=135

In conclusion, x=45, 3x=135, y=45 and z =135

Also note that the opposite angles are equal so you can just find 3x and that will be equal to z and x will be equal to y.

Hope this helped

Step-by-step explanation:

We have ,

x = y ( vertically opposite angles ) 3x = z ( ,, )

As we know ,

Complete angle = 360° x + y + 3x + z = 360° x + x + 3x + 3x = 360° 8x = 360° x = 45°

Hence ,

x = 45° y = x = 45° z = 3x = 45*3 = 135° 3x = 135°.

Answers

Answer:

(-10, -8), third quadrant

Step-by-step explanation:

8 down from (0, 0) is the same as subtracting 8 from the y coordinate → (0, -8). 10 left from (0, -8) is the same as subtracting 10 from the x coordinate → (-10, -8). You would be in the third quadrant where both coordinates are negative.

Which relationship is NOT a function?

Answers

Answer:

Step-by-step explanation:

Answer:

If it is possible to draw any vertical line (a line of constant x) which crosses the graph of the relation more than once, then the relation is not a function. If more than one intersection point exists, then the intersections correspond to multiple values of y for a single value of x (one-to-many).

For three consecutive homework assignments, each assignment had one more question than the previous assignment. The total number of questions on the three assignments is greater than 51 a.Write an inequality to represent this situation, where q is the number of questions on the first assignment

Answers

The inequality that represents the situation is:

[tex]3q + 3 > 51[/tex]

The first assignment had at least 17 questions.

On the first assignment, there were q questions.Each assignment had one more question than the previous one, so the second had q + 1 questions and the third had q + 2 questions.

The total number of questions is:

[tex]T = q + q + 1 + q + 2 = 3q + 3[/tex]

Since the total is greater than 51, the inequality is:

[tex]3q + 3 > 51[/tex]

Solving the inequality, we have that:

[tex]3q > 48[/tex]

[tex]q > \frac{48}{3}[/tex]

[tex]q > 16[/tex]

Thus, it is found that the first assignment had at least 17 questions.

You receive an inheritance of $15,500, and you place the full amount into a bank account. The bank pays a simple interest rate of 7.5% per year. How much interest have you earned after three years?

Round your answer to the nearest dollar.

Do NOT round until you have calculated your final answer

Answers

To solve this we need to figure out what 7.5% of 15,500 is. (It’s 1162.5). Now we know that after one year it is a total of 16,662.5. We then figure out what 7.5% of 16,662.5 is, which is 1,249.6875. You then add that to 16,662.5 which comes out to 17,912.1875. We then figure out 7.5% of that is 1,343.4140625. We then add that to the last total which is 19,255.6015625 and we simplify that to 19,256 and we find out that the final total is $19,256. But it wants how much have we earned which means we need to subtract the original from the new, which is 3756 and we add a unit.

Meaning the final answer is $3,756.

how do you solve n - 8 > 5

Answers

Answer:

n great than 13.

hope this isn't wrong

The solution to the inequality is n > 13. This means that any value of n greater than 13 will satisfy the inequality.

Given is an inequality n - 8 > 5, we need to solve it,

To solve the inequality "n - 8 > 5," you can follow these steps:

Step 1: Add 8 to both sides of the inequality to isolate the variable n.

(n - 8) + 8 > 5 + 8

n - 8 + 8 > 13

n > 13

Step 2: Simplify the inequality.

n > 13

Hence the simplified inequality is n > 13.

How many feet would it descend in 8 minutes?

Answers

Answer:

1. 4 1/2 can be converted into 4.30 / 20 = 0.125f per minute

2. it would descend 4.64 or 5f rounded in 8 minutes (8/0.125)

Answer:

4.45 feet p/m

35.56 feet per 8 minutes

Step-by-step explanation:

20 / (60x4.5) = 60 seconds = ( 1 x 4.5 minutes)

20/270=0.0740740741 1 = multiplier of feet/seconds

60 x 0.0740740741 1 =4.44444445 feet in one minute = 4.45feet

-8(5n - 2) - (n + 3) = 54

Answers

1. Distribute the -8 to 5n and -2 by multiplying.
2. Your problem should now look like this: -40n+ 16 -(n+3)= 54
3. Next distribute the negative to (n+3).
4. After doing that the problem should look like this: -40n + 16 -n -3= 54
5. Combine like terms to get the problem to look like this: -41n + 13=54
6. Subtract 13 from both sides.
7. Now you are left with -41n=41
8. Divide by -41 to both sides.
9. Your answer should be n=-1
