Answer: 18 and 36
Step-by-step explanation:
The scale is 8m for every 2 in and the actual area is 144m2 so we need to covert that into inches. You divide 144 by 8 which = 18 and then multiply 18 x 2 which is equal to 36.
Answer:
180 fb*lb
45 ft*lb
Step-by-step explanation:
We have that the work is equal to:
W = F * d
but when the force is constant and in this case, it is changing.
therefore it would be:
Where a = 0 and b = 30.
F (x) = 0.4 * x
Therefore, we replace and we would be left with:
We integrate and we have:
W = 0.4 / 2 * x ^ 2
W = 0.2 * (x ^ 2) from 0 to 30, we replace:
W = 0.2 * (30 ^ 2) - 0.2 * (0 ^ 2)
W = 180 ft * lb
Now in the second part it is the same, but the integral would be from 0 to 15.
we replace:
W = 0.2 * (15 ^ 2) - 0.2 * (0 ^ 2)
W = 45 ft * lb
Answer:
Jess is 26, Cece is 29

Answer:
Step-by-step explanation:
<u>Given functions</u>
- f(x)= -3/4x
- g(x)= -5x
- h(x)= 5/7x
- j(x)= 11/3x
To compare steepness we'll compare absolute values of slopes
The steepness increases as the slope increases
<u>The slopes are </u>
<u>Comparing the fractions</u>
- 3/4 = 21/28, 5/7 = 20/28, so 3/4 > 5/7
And
<u>So the order is </u>
<u>As functions, the order is</u>
Answer: y=x^2
Step-by-step explanation: There are first of all squares, so you have to multiply the sides. Well and the figure 2 has a side of two smaller squares. So you know x is the argument, in this case the number of the figure, because it is regularly you know that x as example for figure 7 is seven so you have to multiply 7 by 7. This isn’t linear.
