Answer: B. Square
Step-by-step explanation:
- All sides of a square have the same length
- All four angles of a square = 90°
- A square has two parallel sides
Answer:let x be the number of cars, and 7-x be the number of trucks.
25x + 30(7-x) = 195
25x + 210-30x = 195
5x = 15
x = 3
So, 3 cars were not rented. If 7 total vehicles were not rented, 7 - 3 cars = 4 Trucks
4 Trucks were not rented.
Step-by-step explanation:
The maximum height the ball achieves before landing is 682.276 meters at t = 0.
<h3>What are maxima and minima?</h3>
Maxima and minima of a function are the extreme within the range, in other words, the maximum value of a function at a certain point is called maxima and the minimum value of a function at a certain point is called minima.
We have a function:
h(t) = -4.9t² + 682.276
Which represents the ball's height h at time t seconds.
To find the maximum height first find the first derivative of the function and equate it to zero
h'(t) = -9.8t = 0
t = 0
Find second derivative:
h''(t) = -9.8
At t = 0; h''(0) < 0 which means at t = 0 the function will be maximum.
Maximum height at t = 0:
h(0) = 682.276 meters
Thus, the maximum height the ball achieves before landing is 682.276 meters at t = 0.

Answer:
3/10
Step-by-step explanation:
1/5 of <u>total</u> income - spent on car
<u>remainder</u><u> </u> income = 4/5
3/8 of <u>remainder</u><u> </u>= 3/8 ×4/5 = 3/10(of total income spent on rent)
the word "<u>of</u>" means you can find it by multiplication
e.g. 2 of 1/2 means 2 × 1/2 which is 1
The slope of a line perpendicular to this is (y=a number) 0. That's because the change in the x would be 0, because it would be y=3 or something like that.
The slope of a line parallel to this is undefined. That's because it has the same slope as this line, and this line has a slope of undefined.
