Step-by-step explanation:
cos(52) × 15 gives you the adjacent which is 9.2
Since the Figure is not given let me answer the items above by concept.
(b) The intervals during which the acceleration of the bus is constant is the portion where the graph is a line that is neither horizontal or vertical.
(c) The area bounded by the curve and the x-axis is the distance. To get the average velocity, determine the total distance and divide by the total time interval.
(d) The acceleration is determined by calculating the differences between velocities and dividing this difference by the difference of time interval.
It would be great if you attached the spreadsheet
Answer:
2.7 hours
Step-by-step explanation:
We can use the formula
1/a + 1/b = 1/c
where a and b are the times working alone and c is the time working together
1/8 + 1/b = 1/2
Multiply each side by 8b to get rid of the fractions
8b( 1/8 + 1/b = 1/2)
b + 8 = 4b
Subtract b from each side
b+8-b = 4b-b
8 = 3b
Divide each side by 3
8/3 = 3b/3
2.666666repeating = b
Round to 1 decimal place
2.7 = b
Answer:
They are equal, and thus, the triangle is a right triangle. ... When the side lengths of a triangle are in the ratio 3: 4: 5, then it is a right triangle. These sides are 6: 8: 10, then the triangle is a right one.
