Answer: She is 42 Years Old.

Step-by-step explanation: If She is 3 times her age, you have to multiply. and That means you have to do 14 x 3. and that equals 42. Good Luck on Your Test!

<h2><u><em>14 x 3 = 42</em></u></h2>

Prove the following identity true. Show work.
yulyashka [42]

Answer:

The  Pythagorean identity states that

\sin^2 t + \cos^2 t = 1

Using that we can rewrite the left denominator as:

1 - \sin^2 t

Which can be factored as

(1 - \sin t)(1+ \sin t)

The numerator we can expand as:

(1 - \sin t)(1 - \sin t)

On the right hand side, let's multply numerator and denominator with (1 - sin t):

The total formula then becomes:

\dfrac{(1-\sin t)(1-\sin t)}{(1 - \sin t)(1 + \sin t)} = \dfrac{(1-\sin t)(1 - \sin t)}{(1+\sin t)(1 - \sin t)}

There you go... left and right are equal.

The moon is about 240000 miles from earth.What is the distance written as a whole number multiplied by a power of ten
Sauron [17]
A whole number? ok. 24x10^4. usually though you would use standard form so it would be 2.4x10^5

Use the four functions below for this question:
Jlenok [28]

Answer:

We have four functions:

For f(x) we have two points (-2,2) and (-1,-1)

we will use two point form which is:

y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)

So, on substituting the values we get:

y-2=\frac{-1-2}{-1-(-2)}(x-(-2))

y-2=\frac{-3}{x+2}

y=-3x-4

So, f(x)=-3x-4

We have g(x)=3x-4

Now, we will from h(x) we have two points  let initial point on monday is (0,4) and tuesday (1,1) again use two point form we get:

y-4=-3(x-0)

\Rightarrow y=-3x+4

So, h(x)= -3x+4

Now, we will form j(x) we have three points (2,10) , (-2,6) and (2,22)

We will use (-2,6) and (2,22)  to find the function with two point form.

y-6=\frac{22-6}{2+2}x+2)

\Rightarrow y=4x+14

j(x)= 4x+14

To find the slope we will compare the given function with general equation which is y= mx +c; m is the slope

And to find y-intercept we will put x=0

f(x)=-3x-4

Slope is: -3

And y-intercept is: (0,-4)

g(x)=3x-4

Slope is: 3

And y-intercept is: (0,-4)

h(x)= -3x+4

Slope is: -3

And y-intercept is: (0,4)

j(x)= 4x+14

Slope is: 4

And y-intercept is: (0,14)
