6 0

Answer:

sin(A)=\frac{h}{c}

Step-by-step explanation:

we know that

The value of sine of an angle in a right triangle is equal to the opposite side of the angle divided by the hypotenuse

so

sin(A)=\frac{h}{c}

What point on the graph of y = 0.5f(x) corresponds to (4, 16)? Explain.
SVETLANKA909090 [29]

We are given a coordinate (4,16).

Where first coordinate is the value of x and second coordinate is the value of y for the function y=f(x).

We need to find the value of given point (4,16) for function y= 0.5f(x).

Here function f(x) is being multiplied by 0.5.

On multiplying 0.5 by y, it will effect the value of y only. It does not effect value of  x . Because x value is still x. Only function f(x) is being multiplied by 0.5.

Therefore, y= 0.5f(4) = 0.5 * 16 = 8.

So, (4,8) is the point on the graph of y = 0.5f(x) corresponds to (4, 16).

Can someone help me with this problem???
Ber [7]
1. linear equation

2. rearrange the equation so 4y = 12 - 3× and then divide both sides by 4 to get:
y = 3 - 3/4×

3. equation of a straight line / linear equation

4. gradient is + 3

5. not sure sorry

6. 3x = 12 - 4y. Divide each side by 3 to get:
x = 4 - 4/3y

7. use y = 3 - 3/4x by doing and x and y table. So when x = 1, y = 3 - 3/4 (1) (replace the x which the x value you've chosen). Then plot.

8. Make up any problem such as weather, food, etc.

Hope that helps !

Which of the following statements is true?
Harlamova29_29 [7]

Answer:

C

Step-by-step explanation:

A) not true. Sin A = some decimal

Cos 720 = 1

D) That means that d is not true either. not true

B) Sin55 = cos55 is not true either only sin(45) = cos(45) is true. So B is not true.

That leaves C. I think if you check it, you'll find it is right. sin(A) = cos(90 - A)
