Answer: I believe the answer is 88
~i hope that is answered your question correctly, have a gr8 day/night my friend!~
Step-by-step explanation:
Answer:
c is the answer for the question
Well you have to subtract. i think you have to do 15-10% which is 14.9
Answer:
y=-4x^2+9x+9
Step-by-step explanation:
1st: we assume the equation will be in standard form (ax^2+bx+c)
2nd: since the graph passes through (0,9) then the y-intercept is @(0,9) or your c is 9.
3rd: since it passes through (2,11) then 11=4a+2b+c
4th: since it also passes through (3,0) then 0=9a+3b+c
* so we have c=9, 11= 4a+2b+c, and 0= 9a+3b+c*
So a=-4, b=9, c=9
plug in the numbers and you get y= 4x^2+9x+9
Hope this helps you. :3
So we are trying to find this red line's length.
We can either find it directly, or use the blue line firs, and then use it as a leg for the green triangle.
So the blue leg is a hypotenuse for two of the edges. So:
from the Pythagorean Theorem
OR
Which works out to:
So now that we have that, using the Pythagorean Theorem again gives:
So the length of the red line is found that way.
But wait! There's more!
As it turns out, the red line can be found with an easier way that works with cubes and boxes (cuboids). It's really easy:
Where a, b, and c are all 10m, and d is the red line. This greatly reduces the math:
which gives the same answer as above, which you can see.
