The answer is 10 inches :3

Answer:

10 inches

Step-by-step explanation:

They're 36 degrees, so corresponding angles are the same, so the middle line is parallel to the bottom line of the triangle.

But the middle line bisects one of the waist lines of the triangle, so this is the middle line, which is equal to half the length of the bottom line

Verify which of the following are identities.
ch4aika [34]

Answer:

C

Step-by-step explanation:

Equation 1:

1+\frac{\cos^{2} \theta}{\cot^{2} \theta(1-\sin^{2} \theta)}\\ \\ 1+\frac{\sin^{2} \theta}{\cos^{2} \theta} \\ \\ 1+\tan^{2} \theta \\ \\ \sec^{2} \theta

Equation 2:

15\cos \theta \left(\frac{1}{\cos \theta}-\frac{\cot \theta}{\csc \theta} \right) \\ \\ 15\cos \theta \left(\frac{1}{\cos \theta}-\frac{\cos \theta / \sin \theta}{1/\sin \theta} \right) \\ \\ 15\cos \theta \left(\frac{1}{\cos \theta}-\cos \theta \right) \\ \\ 15\cos \theta \left(\frac{1-\cos^{2} \theta}{\cos \theta} \right) \\ \\ 15(1-\cos^{2} \theta) \\ \\ 15\sin^{2} \theta

If f(x) = 5x, what is f–1(x)?
ch4aika [34]

For this case we have the following function:

f (x) = 5x

We want to find the inverse of the function.

The first thing we should do is rewrite the function:

y = 5x

From here, we clear the value of x.

We have then:

x =\frac{y}{5}

Then, returning the variable changes, we have that the inverse function is:

f ^ {-1} (x) =\frac{x}{5}

Answer:

The inverse function of f (x) is:

f ^ {-1} (x) =\frac{x}{5}

Calculate the rate of change.<br> 0    1   2    3    4   5<br> 15 25 40 60 85 115
Arte-miy333 [17]
Dy/dx=10,15,20,25,30

d2y/dx2=5,5,5,5,5  (there is no "rate of change" that is constant because acceleration is positive meaning that velocity keeps increasing...)

Since d2y/dx2 is constant, acceleration is constant, and this means that it is a quadratic equation of the form y=ax^2+bx+c

There are only three unknowns so we can use just three data points.

9a+3b+c=60
4a+2b+c=40
a+b+c=25  getting differences between these...

5a+b=20
3a+b=15  and again...

2a=5, so a=2.5, making 3a+b=15 become:

7.5+b=15, so b=7.5, making a+b+c=25 become:

2.5+7.5+c=25, so c=15

So the quadratic which produced the table is:

y=2.5x^2+7.5b+15

This is the regular old position function you see with any object moving with constant acceleration (like gravity when simplified).

The acceleration is 2.5 it has an initial velocity of 7.5 and an initial position of 15.
