67/100 17/25 69/100 and 7/10
Answer:
= x
Step-by-step explanation:
Basically, find the missing side lengths of each triangle so that you can solve for x:
1. right triangle w/ side lengths 48 and 52
- 48^2 + (missing side)^2 = 52^2
- 2304 + (missing side)^2 = 2704
- (missing side)^2 = 400
- (missing side) = 20 (use this for next triangle)
2. right triangle w/ side lengths 12 and 20 (from previous triangle)
- 12^2 + (missing side)^2 = 20^2
- 144 + (missing side)^2 = 400
- (missing side)^2 = 256
- (missing side) = 16 (will be used with next triangle's missing side)
3. right triangle w/ side lengths 5 and 13
- 5^2 + (missing side)^2 = 13^2
- 25 + (missing side)^2 = 169
- (missing side)^2 =144
- (missing side) = 12
Take right triangle w/ side lengths 12, 20, and 16 (#2) and right triangle w/ side lengths 5, 13, and 12 (#3):
- the value of 12 (missing side of #3) subtracted from the #2's missing side, 16, (not its hypotenuse that equals 20 which was found from #1) will equal <u>the missing side length that will be used to find 'x'</u>
- 16 - 12 = 4 ---> so the side lengths are 4, 5, and x
4. Solve for the final triangle that includes x:
- 4^2 + 5^2 = x^2
- 16 + 25 = x^2
- 41 = x^2
- = x

, while
for
and
for
. So you already know that
over the second half of the interval.
In the first half,
is an increasing function, from
to
. Meanwhile
is a decreasing function, from
to
. Therefore there must be a point between 0 and
where the two curves intersect. So we find it:
So we know that
in
, and
in
.
The area between the curves is then
Answer:
Petroleum = 15.32%
Drugs = 12.9%
Chemicals = 2.5%
Motor Vehicles = -56.5% (Negative)
Electrical = -18.8% (Negative)
Food = 3.7%
Step-by-step explanation
Here we have to use the formula to find the percentage of increase.
Percentage of increase = Increased amount / original amount * 100
Let's find the percentage of increase of each firm from 1966 and 1974
Petroleum = ((12.8 - 11.1) ÷ 11.1)) *100 = (1.7 ÷ 11.1)*100 = 15.32%
Drugs = ((12.2 - 10.8) ÷ 10.8)) *100 = (1.4 ÷ 10.8)*100 = 12.9%
Chemicals = ((8.2 - 8) ÷ 8)*100 = (0.2 ÷ 8)*100 = 2.5%
Motor Vehicles = ((2.7 - 6.2)÷6.2)*100 = (-3.5÷6.2)*100 = -56.5% (Negative)
Electrical = ((3.9 - 4.8)÷4.8)*100 = (-0.9÷4.8)*100 = -18.8% (Negative)
Food = ((2.8-2.7)÷2.7))*100 = (0.1 ÷2.7)*100 = 3.7%
Hope you will understand the concept.
Thank you.
