Answer:
3^x+12x-4
Step-by-step explanation:
(f+g)(x) = f(x) + g(x) = 3^x + 10x + 2x - 4 = 3^x + 12x - 4
describes a sum of the areas of 50 rectangles, each of width
, and the
th rectangle has height
.
ranges from a small positive number to 1, which means the integration interval must be
![[0,1]](https://tex.z-dn.net/?f=%5B0%2C1%5D)
. The sum is then the right-endpoint Riemann sum of
over the interval with
equally spaced subintervals, so
The sum itself evaluates to roughly 0.676, while the exact value of the integral is
.
Answer:
x = 6
Step-by-step explanation:
Since <F = <F, this shows that the triangles are similar. Therefore:
XZ/DF = XY/DE
12/8 = 9/X
Cross multiply
12X = 9*8
12X = 72
X = 72/12
X = 6
Hence the value of x is 6
Well, we can really show our work because their is no work to be done. Question 7 is a right angle because it is exactly 90 degrees. So since you now know what a right angle is, you can probably guess Question 8 a would be either 3 o'clock or 9 o'clock. For question 8b , he first one, and acute angle is an angle where it is below 90 degrees. So an example of an acute time is 3:05. An obtuse angle is an angle above 90 degrees. So an obtuse time would be (for example) 3:55. Hope this helped.
