Answer:
f(- 2) = 1
Step-by-step explanation:
f(- 2) means what is the value of f(x) when x = - 2
From the table we can see that when x = - 2 f(x) = 1
Hence
f(- 2) = 1
Using the Pythagorean Theorem, we have x^2+(x+2)^2=51^2, and
x^2+ x^2+4x+4=2x^2+4x+4=51^2. After that, we subtract 51^2 from both sides to get 2x^2+4x-2597. Using the quadratic formula (x=(-b+-sqrt(b^2-4ac))/2a in ax^2+bx+c), we get around 35 for x. We did + instead of minus after b due to that it can't be negative! x+2=37, so you save 35+37-51=around 21 feet
Answer:
70 min
Step-by-step explanation:
If we take the hypothesis that by the end of the fifth day he had 5h20min drums practice then the remaining time to get to 7 hours practice time would be 1h40min.
f(x) > 0 - I and II quadrant
f(x) < 0 - III and IV quadrant
Look at the picture.
A. F(x) < 0 on the interval x < 0. TRUE
B. F (x) > 0 on the interval x <0. FALSE
C. F (x) < 0 on the interval 0 < x < 1. TRUE
D. F (x) > 0 on the interval 0 < x < 1. FALSE
E. F (x) < 0 on the interval 1 < x < 3. FALSE
F. F (x) > 0 on the interval 1 < x < 3. TRUE
G. F (x) < 0 on the interval x > 3. TRUE
H. F (x) > 0 on the interval x > 3. FALSE
Short Answer: C
I hope these taxes are not compounded. Some places do that.
Total tax = 9%
First figure out the cost of the room for 2 nights
C = 89 + 89
C = 178
There are two ways to add on the 9%. Both ways require that you change 9% to a decimal
9% = 9/100 = 0.09
The first way is just to take 9% of 178
9% 178 = 0.09 * 178 = $16.02
And add this onto 178
C1 = 178 + 16.02
C1 = 194.02
Answer 194.02
C <<<<< answer
Or you can solve this more directly by adding 0.09 onto 1
1.09 * 178 = 194.02 which is the answer.
Answer = C <<<<
