Answer:
ms. sempe is right.
.
first we'll find area of trapezium.
area of trapezium = 1/2×height×(sum of parellel sides of the trapezium)
area of trapezium =1/2×4×(13+24)
area of trapezium =1/2×4×37
area pf trapezium = 74in²
now area of rectangle.
area of rectangle = length ×width
area of rectangle= 24in×7in
area of rectangle =168 in²
area of the figure= 74in²+168in²
area of figure=242in²
The graph of the car's speed is a piece of an inverted parabola,
that cuts the time axis at zero and at 8 sec.
The distance the car travels during that 8 seconds is the area
between the parabola and the time axis. If you intend to calculate
it, then I'm afraid you're going to need to integrate the speed function.
V = 24t - 3t²
Distance = integral of (24t - 3t²), evaluated from zero to 8 seconds.
Integral of (24t - 3t²) =
t²/2 - 3t³/3 = <u>12t² - t³</u>
Evaluated between zero and 8 seconds, the integral is
12(8²) - (8)³ =
768 - 512 =<em> 256 meters</em> .
10 - 6v = -104 add 10 on both sides which is going to be -6v = -104 then you divide -6 on both sides and v = 17.3
Answer:
second option
Step-by-step explanation:
The x- intercepts are the values on the x- axis where the graph crosses.
These are
x = - 3, x = - 1 and x = 3
The angles in a triangle must add up to equal 180. When it gives you angle A and angle B, you add them, then subtract it from 180, which will give you the angle C.
65 + 15 = 80
180 - 80 = 100 = Angle C.
It says to list them from smallest to greatest.
<B = 15, <A = 65, <C = 100
