Area of 3400 decreases by 7.25%.
Rewrite 7.25% as a decimal.
This leads to 0.0725.
So, (3400)(0.0725) = 246.5.
Now (246.5)(13 years) = 3,276.
The area after 13 years will be
3,276 km^2.
Answer:
1. The car is slowing down at a rate of 2.5mph/s
2. The greatest acceleration is 10 mph/s.
3. In the interval 4s to 16s the speed remains constant and has magnitude 25 mph.
Step-by-step explanation:
1. The deceleration of the car is from 16 seconds to 24 seconds is the slope of the graph from 16 to 24:
the negative sign indicates that it is deceleration.
2. The automobile experiences the greatest change in speed when the slope is greatest because that is when acceleration/deceleration is greatest.
From the graph we see that the greatest slope of the graph is between 28 and 24 seconds. The acceleration the interval is the slope :
3. The automobile experiences no acceleration in the interval 4 s to 16 s—that's the graph is flat.
The speed of the automobile in that interval, as we see from the graph, is 25 mph.
Answer:
infinite
Step-by-step explanation:
10^2 + 4 * (6 + 3) - 27 ÷ (9 - 6) = 127
=100 + 4 * 9 - 27 ÷ 3
multiplication & division before addition and subtraction (order of operations rules, PEMDAS)
100 + 36 - 9= 127
136 - 9= 127
127= 127
Place a set of parentheses around (6+3) and (9-6).
Hope this helps! :)
Answer:
x = 38.2°
Step-by-step explanation:
<u> sin 27° </u> = <u> x° </u>
11 15
15 · (sin 27°) = 11 · x°
cross-multiply:
6.81 = 11x
6.81 / 11 = x
x = 0.619
sin^-1 (0.619) = 38.2°
