X is the hypotenuse of an isosceles triangle. The length of the sides are the difference of the inner and outer squares divided by 2. Which means that the sides of the triangle is 1.5 inches. Using that information, the length of X can be deduced to be 2.12 inches using Pythagoras theorem

A function has a constant doubling time. What type of function does this<br> represent?

SIZIF [17.4K]

Answer:

an exponential function

Step-by-step explanation:

An exponential function has the characteristic that it increases by a constant factor when the independent variable increases by a constant increment. The function you describe is an exponential function.

__

It can be written in the form ...

f(t) = f(0)·2^(t/d) . . . . . where d is the doubling time

This is so confusing all of it makes no sense

Tom [10]

Answer:

D). $4\sqrt{2}$

Step-by-step explanation:

<u>STEP 1a:</u> Find the last angle of the triangle. ( which is angle A)

$A+90+45=180$

<u>STEP 1b:</u> Solve the equation for A by adding 90 and 45.

$A+135=180$

<u>STEP 1c:</u> Then Move all terms not containing A to the right side of the equation by subtracting 135 from both sides of the equation

$A=180-135$

<u>STEP 1d:</u> Subtract 135 from 180.

$A=45$

STEP 2a: Find side b next.

STEP 2b: The cosine of an angle is equal to the ratio of the adjacent side to the hypotenuse.

$cos(A)=\frac{adj}{hyp}$

STEP 2c: Substitute the name of each side into the definition of the cosine function.

$cos(A)=\frac{b}{c}$

STEP 2d: Set up the equation to solve for the adjacent side, in this case b.

$b=c*cos(A)$

STEP 2e: Substitute the values of each variable into the formula for cosine.

$b=8*cos(45)$

STEP 2f: Cancel the common factor of 2.

$a=4\sqrt{2}$

Answer:

Well, in math..

for example, There is triangle ABC, and ur translating it 3 units to the right on a grid...

The new triangle will be called A'B'C' cause its a new one... and to differenciate from the two, to not get mixed up, between them
