Luke and his friends are going on a road trip that is 5173750 miles long. They have already driven 3123100 miles. How much farther do they have to drive? Answer in decimal form.

They have to drive 2,050,650 more miles. Which is also 0.4 of the whole road trip.

Step-by-step explanation:

Subtract the miles they have already driven from the miles of the entire trip. Then use that and divide it by the miles of the entire trip and you'll get 0.4.

the answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!

center (1,3) with radius 6

step-by-step explanation:

we must complete the square to find the center and radius of the circle.

first make sure the x and y squared terms have 1 as their coefficients. we also make sure x and y terms together.

we now create space between the x and y terms with parenthesis.

we complete the square by taking the middle terms -2x and the -6y - divide each and square them.

we add the squares to both sides.

simplify.

and write the quadratics in factored form.

the center is (h,k) or (1,3). the radius is the square root of 36 which is 6.
