Answer:

-9 ≤ y ≤ 5

Step-by-step explanation:

The range is all the values of y. In this case, the values of y are any number in between -9 and 5. So -9 ≤ y ≤ 5.

Someone help I don't know what the diameter or radius is

<h3>Answer:</h3>

52.38 inch² & 261.90 inch²

<h3>Step-by-step explanation:</h3>

Here we need to find the area of the sector . So according to formula we know the area of sector as ,

$\boxed {\sf Area_{(sector)}= \dfrac{\theta}{360}\times \pi r^2 }$

Here we can see that the central angle subtended by the arc is 60° and the radius of the circle is 10 inches . So the required area would be ,

=> Area = ∅/ 360° × π r²

=> Area = 60°/360° × 22/7 × (10in.)²

=> Area = 1/6 * 22/7 * 100 in²

=> Area = 52 .380 in²

<h3>★ Hence the area of the red sector is 52.38 inch².</h3>

_________________________________

Now let's find out the area of blue sector .The angle subtended by the arc will be (360-60)°=300° .

=> Area = 300/360 × 22/7 × 100 in²

=> Area = 261. 90 in²

<h3>★ Hence the area of blue sector is 261.90 inch².</h3>

$\boxed{\red{\sf Area _{(red \ sector )} = 52.38 in^2 }}$

$\boxed{\blue{\sf Area _{(blue \ sector )} = 261.90 in^2 }}$

Find the measure of each marked angle. Assume the lines are parallel. (2x - 30)° = (x+3)° =

Ket [755]

Answer:

Measure of each angle = 36°

Step-by-step explanation:

$(2x - 30) \degree = (x + 3) \degree \\ (alternate \: \angle \: s) \\ \\ 2x - 30 = x + 3 \\ \\ 2x - x = 30 + 3 \\ \\ x = 33 \\ \\ (2x - 30) \degree \\ = (2 \times 33 - 30)\degree \\ = (66 - 30)\degree \\ = 36 \degree \\ \\ (x + 3) \degree \\ = (33 + 3) \degree \\ = 36\degree$

A flare is launched from a life raft with an initial upward velocity of 192 feet per second. How many seconds will it take for t

AVprozaik [17]

So you want height to be 0 so you plug zero into the height and solve from there. You subtract 192 from both sides to get -192=-16tsquared. Then you would divide by -16 and end up with 12 = t^2. Then you find the square root of 12 and get t = 3.464 seconds.
