Answer:
Solution given:
7x-29=2x+16[length from the circumference of circle is equal to same point]
7x-2x=16+29
5x=45
x=45/5=9
now.
XY=2×9+16=18+16=34 is your answer
Answer:
12
Step-by-step explanation:
f(x)=x^+4x+2 First, let's evaluate when x=3, x=4 and x=5.
f(3) = 3²+4(3)+2 = 9 + 12 + 2 = 23
f(4) = 4²+4(4)+2 = 16 + 16 + 2 = 34
f(5) = 5²+4(5)+2 = 25 + 20 + 2 = 47
Now, let's find the rate of change.
34 - 23 = 11
47 - 34 = 13
Finally, the average rate of change.
(11 + 13) / 2 = 12
Answer:
w = -60
1. w + 16 = -44
2. w + 16 - 16 = -44 - 16
Solution is -60.
Well see here that it practically gives us the answer. The submarine rises 4.3 meter each minute of the first 15 minutes. Multiplying these two given numbers you get 64.5 . Great we're halfway through. Now onto the second equation. 5.2 times 12 . easy right? The answer round to 62.4 . Now all that's left to do is add the two together. After the 27 minutes the submarine should be at an elevation of 126.9 feet. rounding to 127 if you teacher requires you to round the numbers.
C is 12 and x is 3 and that would be your variables
