The correct answer is: 23

Explanation:

Given function:

f(x) = 3x^2 - 2x + 7 ---- (A)

f(-2) means that we have to put x = -2 in equation (A):

f(-2) = 3(-2)^2 - 2(-2) + 7 \\ f(-2) = 3*4 + 4 + 7 \\ f(-2) = 12+4+7 \\ f(-2) = 23 \\


Hence the correct answer is: f(-2) = 23.

Bill drove his car at a constant speed while on a trip. Kevin drove his car at a different constant speed while on the same trip
Step2247 [10]
I thought to say the second sentence because it says that he’s going at a different constant speed but he doesn’t say compared to who... I’m leaning more to the last sentence.
What do you think?

<h3>Answer:  983,700,000</h3>

=========================================================

Explanation:

The uppercase E represents "ten to the"

So saying E8 means "ten to the 8th power"

In other words, 9.837 E 8 = 9.837 * 10^8

The exponent positive 8 tells us to move the decimal point over to the right 8 spots.

So that's how we go from 9.837 * 10^8 to 983,700,000

There are 5 zeros in that value after the "9837" portion.

When we move from 9.837 to 9837.0, that's exactly 3 spots so far. Then the decimal point has to move another 5 spots to go from 9837.0 to 983,700,000 which is therefore 3+5 = 8 total shifts to the right.

The number 983,700,000 is slightly over 983 million. If anything, it's more closer to 984 million.
