A police officer paid 10% of her income between 0 and 8,350: 0.10*8350=$835
<span>A police officer paid 15% of her income between 8350 and 33,950: 33,950-8,350=25,600⇒0.15*25,600=$3,840
</span>A police officer paid <span>25% of her income between 33,950 and 47,050: 47,050-33,950=13,100⇒0.25*13,100=$3,275
$835+$3,840+$3,275=$7,950
</span><span>The policy officer paid $7,950 in federal income tax.</span>
So when x = -1, you just substitute the variable x to -1.
"4x" means 4 times x, so when x is replaced to -1, that would be 4 times -1.
f(-1) = 4(-1) = -4
So the value of function at x = -1 would be -4.
Hope this helps.
It will be a negative.
for an example: -20 for x would mqke 2x + 1 into -39 and 8x + 5 into -155. that's 116 apart, so maybe -2(8) + 5 = -11
-2(2) + 1 = -3
but that's only 8 apart, so it'd be higher.
-4(2) + 1 = -7
-4(8) + 5 = -27
BOOM
Tadaaaa,
You probably thought positive, but sometimes it's negative, you know what I mean?
First, 90 minutes will equal 1.5 hours. And I have the formula for this is distance=time×speed, so I just take 25 divided 1.5 to get the speed she is riding which equal 16 2/3 miles per hour. Hope it help!
Answer:
$5751.37
Step-by-step explanation:
The key phrase here is "compounded continuously". This phrase tells you that you must use the following equation:
Where A is the final amount, P is the principal amount, e is the exponential constant, r is the rate in decimals and t is time. By plugging in our known values given we obtain:
