Maybe you can study it or figure out a trick. I usually study with my sibling, but if you don't have any, friends or other family. I am sure they won't mind. Also, maybe making flashcards, those work well. 
Also, you can print out worksheets and make your brain remember. PRACTICE!

Answer: B. Line AC is congruent to line BD

Step-by-step explanation:

The Hypotenuse-Leg Theorem states that two right triangles are congruent if and only if the hypotenuse and a leg of one right triangle are congruent to the hypotenuse and a leg of the other right triangle.

Since they both share Leg DC, their hypotenuse should be congruent to use this proof.

On a recent trip to a computer store you purchased one software package for 24.99 and three printer cartridges the total bill wi
DanielleElmas [232]

Answer:

The price of a single printer cartridge is 19.69, in your given currency.

Step-by-step explanation:

First remove the tax and the software package from the total bill.

90.01 - 24.99 - 5.95 = 59.07

Since there are 3 cartridges, you divide 59.07 by 3, giving you the price of a single cartridge.

59.07 \div 3 = 19.69

A sculptor needs to lift a piece of marble.
Dennis_Churaev [7]

Answer:

486kg

Step-by-step explanation:

density = mass / volume

2.7 = m / (100 x 60 x 30)   **** Note the conversion to cm as the density is given in g/cm.

2.7 = m / 180000

m = 486000g

Now convert to mass in kg:

486000 g x 1 kg / 1000 g = 486kg

So the function is
f(x)=3( \frac{1}{3})^{ x }
the intial value is where x=0
where x=0, the value of f(0)=3

grouth is 1/3 but it is decay, so it might be correct, or not because it is decay
it is exponential decay
true it is a stretch of the funciton f(x)=(1/3)^x
when x=3, then f(3)=1/9


the true things are

The function shows exponential decay.
The function is a stretch of the function f(x) = (1/3)x .
