Answer:
(fog)(-6) = 39
Step-by-step explanation:
Look at the image for the explanation :)
If Ricky saves $7 a week, and there are 52 weeks in a year, you can estimate the amount of money he saves by multiplying 7 by 50, which will give you 350 dollars. So, saving $7 every week for 52 weeks will give you a little more than $350.
Answer:
Step-by-step explanation:
C=$200
B=175 frisbees to sell
P=$5
$200-175=$25
25/5=$5
the profit is $5 because you're selling the fribees because you'll be gaining
$5 every sell.
and and you have 175 frisbees to sell so 5x175
$875 you'll gain when you sell them all!!
hope this helps. :D
Answer:
A. 16.55
Step-by-step explanation:
What we know is the angle of 38° and the hypotenuse is 21. Before we find x (side b), we have to find side a first. TO find that multiply the sine of 38 by 21.
21 * sin(38)
<em>sin(38) calculates to 0.615661475.</em>
21 * 0.615661475
<em>Multiply 21 by 0.615661475</em>
side a = 12.928890975
Now to find x. Use this to find x: √21² - 12.928890975²
√21² - 12.928890975²
<em>Square both numbers</em>
√441 - 167.156221843
<em>Subtract 167.156221843 from 441</em>
√273.843778157
<em>Find the square root of 273.843778157</em>
x ≈ 16.548225831
x ≈ 16.55, so the answer is A.
Answer:
Step-by-step explanation:
f(-9+h)= (-9+h)² = h²-18h+81
f(-9+h)-f(-9)=h²-18h+81 -81 because : f(-9) = (-9)² = 81
f(-9+h)-f(-9)=h²-18h
(f(-9+h)-f(-9))/h=(h²-18h)/h = h(h-18)/h =h-18
lim (f(-9+h)-f(-9))/h = lim(h-18= - 18
h→0 h→0
