Scientific notation is the representation of a number in a power of ten, with a sequence of digits placing the comma after the first digit, and the power or then that is mathematically consistent with the number. For example 400 is 4.00 * 10^2; 3100 is 3.100 * 10^4; 13421 = 1.3421 * 10 ^4. It is important that you have only one digit before the comma. So, 5,098,00 is 5.098 * 1,000,00 = 5.098 * 10^6. <span>The answer is the option c. 5.098 * 10^6.</span>
Just draw x where the number gies
F(x) = 3(x-4)^2-38 because finding the perfect square would get you f(x)+38=3(x^2-8x+16) and then finding the squareroot of that and moving the constant on the left back to the right would leave u with f(x)=3(x-4)^2-38
Answer: x = -3.625 or -29/8
Step-by-step explanation:
7-8x+22
1. -Set it equal to 0.
7-8x+22=0
2. Subtract 7 and 22 from both the left and right sides.
7-8x+22=0
-7 -22 -7 -22
8x = -29
4. Divide both sides by 8.
8x=-29
8 8
x= -3.625
Leave it in fraction form if decimal is unacceptable.
hope this helps.
Answer:
$16.25
Step-by-step explanation:
Half a gallon for $2.50 is the same as a quarter a gallon for $1.25.
If she needs 3.25 gallons, which is 13 quarters, we do $1.25 * 13 = $16.25.
Therefore, she will spend $16.25.
