What is the length of the hypotenuse? If necessary, round to the nearest tenth.

Step-by-step explanation:

This triangle has a small square in the corner, representing a right angle. This means we can use the Pythagorean Theorem.

Where a and b are the legs and c is the hypotenuse.

In this triangle, the legs are 2 and 1, because they form the right angle. The hypotenuse, which is opposite the right angle, is unknown.

Substitute the known values into the formula.

Solve the exponents.

Add.

Since we are solving for c, we must isolate the variable. Since it is being squared, we take the square root of both sides.

We have to round to the nearest tenth. The 3 in the hundredth place tells us to leave the 2 in the tenths place.

The hypotenuse is approximately 2.2 inches.

step-by-step explanation:

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
