Answer:
it's 12 because
2×6=12
3×4=12
4×3=12
and all of them have twelve
Answer:
f(x) = (-1/2)(x^2 + 8x - 15)
Step-by-step explanation:
This function has two roots: -3 and 5. Most likely it is a quadratic (all of which have two roots).
Then f(x) = a(x + 3)(x - 5)
The graph goes through (1. 8): Therefore, y = 8 when x = 1:
f(1) = a(1 + 3)(1 - 5) = 8, or
a(4)(-4) = 8, or
-16a = 8, which leads to a = -1/2.
Thus the quadratic in question is f(x) = (-1/2)(x + 3)(x - 5), or
f(x) = (-1/2)(x^2 + 8x - 15)
The number solution set 2 . 30 36
Note the place values:
9 ones place value
. (decimal point)
3 tenths place value
4 hundredths place value
8 thousandths place value
8 ten thousandths place value
You are solving for the tenth place value. Look at the digit directly right of the tenths place value. It is the hundredths place value, which is 4.
Note that when rounding, if the number next to what you are solving for, has a value of 5 or greater, you round up. If it has a value of 4 and less, you round down. In this case, it is a 4, so round down.
9.3488 rounded to the nearest tenth is 9.3
9.3 is your answer.
