Answer:
8.6 × 10-4
Step-by-step explanation:
All numbers in scientific notation or standard form are written in the form m × 10n, where m is a number between 1 and 10 ( 1 ≤ |m| < 10 ) and the exponent n is a positive or negative integer. Therefore, the decimal number 0.00086 written in scientific notation is 8.6 × 10-4 and it has 2 significant figures.
We are given the parent function, f(x) = 5x and is vertically compressed by a factor of 1/2, shifted to the right (3 units) and down two units.
Vertical compression makes the function:
f(x) = (1/2) * 5x
shifted 3 units to the right makes the function:
f(x) = (1/2) * 5 (x+3)
shifted 2 units down makes the function:
f(x) = (1/2) *(5 (x+3)) - 2
therefore, this function is the resulting function after performing all three adjustments of the parent function. First, compression, then shift to left/right, then shift up and down.

Answer:
16 cups of flour
Step-by-step explanation:
step 1 - cups of flour-4, cups of sugar -4
