Which statement about 214° is correct?

Answers

Answer 1

Answer:

Step-by-step explanation:

sin 214 = -0.5591

tan 214 = 0.6745

cos 214 = -0.8290

Answer 2

The correct statement about 214 degrees angle is sin 214 < 0 because sin 214 = -0.5591 and -0.5591 < 0 is true option (A) is correct.

What is trigonometry?

Trigonometry is a branch of mathematics that deals with the relationship between sides and angles of a right-angle triangle.

We have statements:

sin 214 < 0

tan 214 < 0

cos 214 > 0

As we have given trigonometric ratio,

The trigonometric ratio can be defined as the ratio of the pair of a right-angled triangle.

From the trigonometric table:

sin 214 = -0.5591

tan 214 = 0.6745

cos 214 = -0.8290

Plug the above values in the inequality:

-0.5591 < 0 (true)

0.6745 < 0 (false)

-0.8290 > 0 (false)

Thus, the correct statement about 214 degrees angle is sin 214 < 0 because sin 214 = -0.5591 and -0.5591 < 0 is true option (A) is correct.

What is the slope of y = 5x – 1?

Answers

Answer:

Step-by-step explanation:

The equation of a line is y=mx+b. b is the y-intercept when the line is graphed. The y-intercept is when the line intersects the y-axis. m is the slope of the line. In the given equation, m is equal 5, thus the slope is 5.

First try to get the variable p by its self and the whole numbers on the opposite side.

14p - 8 = 22 + 20p

-14p - 14 p

-8 = 22 + 6p

What is the value of 16.43 – 1.043

Pls show the work of how you did it

Answers

Answer:

15.387

Explanation:

16.43
- 1.043
————
15.387

Decimals are cool because you can add zeros to the end of them, and they will still be the same number.

16.43 = 16.430

I add the zero to the thousandths place because I am subtracting a number from 16.430 that has a number in the thousandths place. When you line the two numbers up to subtract you want to make sure they have an equal amount of decimal places.

1 6. 4 3 0 <— you now are ready to subtract.
- 1 . 0 4 3 I lined up the numbers in the
—————— ones, tenths, hundredths + Thousandths place. I drop the decimal point down.

Start from the rightmost digit.
You can’t subtract 3 from 0, so you borrow ten from the left.
3-1 =2. Cross out 3 and write 2 above it.
You add 10 to 0. 10+0=10. Cross out 0 and write 10 above it.
You can subtract 3 from 10 now. 10-3=7.

2 10
1 6. 4 3 0 You now have this.
- 1 . 0 4 3
——————
. 7

You can’t subtract 4 from 2, so you borrow from the left again.
4-1=3. Cross out 4 and write 3 above it. 2+10=12. Cross out 2 and write 12 above it.
12 - 4 = 8.
This is what that looks like:

12
3 2 10
1 6. 4 3 0 You now have this.
- 1 . 0 4 3
——————
. 8 7

3 - 0 = 3.
6 - 1= 5.
1 - 0 (as there is no digit in the tenths place) = 1

12
3 2 10
1 6. 4 3 0 You now have this.
- 1 . 0 4 3
——————
1 5. 3 8 7

So 16.43-1.043= 15.387

7x-4+8x=6x+8 abcdefghijklmnop

Answers

Answer:

x = 4/3

Step-by-step explanation:

7x − 4 + 8x = 6x + 8

Answer:

x=[tex]\frac{4}{3}[/tex]

Step-by-step explanation:

So the equation is 7x-4+8x=6x+8. All we need to do is simplify. On the left side, 7x+8x=15x, so 15x-4=6x+8. Now, we bring the 6x from the right side to the left. When you bring a term from one side to another, you change its sign. As of now, the sign of 6x is positive, so we make it negative and move it to the left side. The new equation is 15x-6x-4=8. Simplifying the left side gives you a new equation of 9x-4=8. Now we move the -4 from the left side to the right side. We change the sign so it becomes 4 and we move it to the right. The equation is now 9x=8+4. 8+4=12, so the final equation is 9x=12. Now we divide by 9 on both sides, giving us the unsimplified answer of x= [tex]\frac{12}{9}[/tex]. We divide the numerator and the denominator by 3 and we get our final answer of x=[tex]\frac{4}{3}[/tex].
