If the velocity of a car on a timed test drive on an airfield is given by the function:

1 answer:

5 0

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 = 12t² - t³

Evaluated between zero and 8 seconds, the integral is

 12(8²) - (8)³ =

 768 - 512 = 256 meters .

How does a 180 degree rotation about the origin change the coordinates of a shape

notsponge [240]

Answer:

According to the 180°-rotation rule, you take the OPPOSITE of both the x-coordinate and y-coordinate:

180°: [x, y] → [-x, -y]

So, I need help with this question and will mark brainliest.

Tcecarenko [31]

Answer:

this an example not the answer i don't know the answer

E is between D and F.

Given: E is between D and F

Prove: DE = DF − EF.

Statements Reasons

1. E is between D and F Given

2. D, E, and F are collinear points, and E is on ¯DF Definition of between

3. DE + EF = DF Segment Addition Postulate

4. DE = DF − EF Subtraction property of equality

2. If →BD divides ∠ABC into two angles, ∠ABD and ∠DBC, then m∠ABC = m∠ABC - m∠DBC.

Pls hurry least to greatest

liraira [26]

Answer:

First choice

Step-by-step explanation:

Start by arranging the exponents of 10 in ascending order.

9.4 * 10^-8, 9.25 * 10^-6, 2.5 * 10^3, 7 * 10^3

The exponents are in ascending order, -8, -6, 3, 3

Since the last two exponents are equal, we must compare the numbers that multiply the powers of 10. They are 2.5 and 7. Since 2.5 < 7, ascending order is 2.5, 7. That means the line above is in ascending order.
