In a 100m race an athlete took 9.8 seconds:
a) Draw a distance-time graph to represent this information
b) determine the average velocity
c) distance traveled in 3 seconds
d) the time taken to cover 80m

Answers

Answer 1

Step-by-step explanation:

b) average velocity : ∆x/∆t = 100/9.8 ≈ 10.204 m/s

c) ∆x = v.∆t = 10.204 × 3 = 30.612 m

d) ∆t = ∆x/v = 80/10.204 = 7.84 s

AS the expressions on the right are both equal to y:

3x + 7 = -2x - 3

3x + 2x = -3 - 7

5x = -10

x = -2

The area of a sector of a given circle is 37.7 m².

Given that, the radius of a circle=4 m and the central angle of a circle=270°.

What is the formula to find the area of a sector?

The area of a sector is the space inside the section of the circle created by two radii and an arc. It is a fraction of the area of the entire circle.

The formula to find the area of a sector is θ/360°(πr²).

Where r is the radius of the circle and θ is the angle of the sector.

Now, area=270°/360°(3.14×4×4)=37.68≈37.7 m².

Therefore, the area of a sector of a given circle is 37.7 m².

which of the following correctly gives the center and radius of the circle defined by the equation (z-7)^2 = 10?

Answers

Hi there!

[tex]\large\boxed{\text{Center: (7,2); radius =} \sqrt{10}}}[/tex]

We know that the standard form of the graph of a circle is:

(x - h)² + (y - k)² = r²

Where:

h = x-coordinate of center

k = y-coordinate of center

r = radius

We can identify the following from the given equation:

(x - 7)² ⇒ h = 7

(y - 2)² ⇒ k = 2

r² = 10 ⇒ r = √10

Thus, the correct answer is C.
