Answer:
x+x+1+x+2+x+3=190
4x+6=190
4x=184
x=46
Step-by-step explanation:
the numbers are 46&47&48&48
so your answer is 48
Answer:
C. 10
Step-by-step explanation:
We are given a graph representing the height of the elevator with respect to time.
Since, we know that,
X-axis represents the 'time' in seconds and y-axis represents the 'height of the elevator' in feet.
As, the coordinate points on the graph are given by,
(1,10), (2,20), (3,30) and (4,40).
So, the rate of change can be found out by solving,
.
Hence, the rate of change of the relationship is 10.
That's again the derivative at 2, so the answer is A. 4. Hard way:
f(x)=x²
f(2)=4
f(2+h) = (2+h)² = 4 + 4h + h²
f(2+h) - f(2) = 4h + h²
(f(2+h)-f(2))/h = 4 + h
Limit is 4.
Answer: A. 4
So hmm notice the picture below
the triangular prism, is really just 3 rectangles and 2 triangles, stacked up to each other at the edges
now, just get the area of the triangles and the rectangles, and add them up, and that's the surface area of the triangular prism
now, what's the length "x"? well
