Answer:
A.
Step-by-step explanation:
when a value is outside of the root, then you can square it and put it back in. After you put it back in, you need to multiply it by the number that is remaining
In this case, you would square 10 which equals 100, and put it back into the root and multiply 100 by 5.
100x5=500
Therefore, the answer is A, root 500
Answer:
RS=12
Step-by-step explanation:
The whole line is 15 units
part of the line is 3 units
the part of the line without measure would be
15 - 3 units so 12 units
Answer:
c(x) = –8x^2 + 3x – 5 is a quadratic
Step-by-step explanation:
A quadratic function involves the 2nd power of x: x^2, and may (or may not) involve the 1st and zeroth power of x.
a(x) = -2x^3 is not a quadratic because of that exponent 3; in a quadratic, the highest power is always 2.
b(x) = 5x^3 + 8x^2 + 3 is not a quadratic for the same reason that a(x) is not a quadratic.
c(x) = –8x^2 + 3x – 5 is a quadratic: the highest power of x is x^2, the other powers are x^1 and x^0.
C) $694.25
Why?
Because you want to times the interest by 2 (1 is for one year but u want to find the amount after two years) then you multiply the amount given to each bank separately so:
400*0.07 (7% which is 7/100) = 28
250*0.065 (6.5% which is 65/1000) = 16.25
Then u add the interests together:
28+16.25 = 44.25
Finally you add that to the amount you started with:
$650+$44.25= $694.25
It would be 10 miles since we use Pythagorean Theorem
