p(110+90)=520

p(200)=520

520/200 = 2.6 hours = 2 hours and 36 minutes

A cannon is placed on high ground 24 ft above a target that is 1000 ft away horizontally. It fires a projectile upward at a 45°
topjm [15]

Answer:

D. vo = 125(2)^1/2

Step-by-step explanation:

Range of a projectile is the defined as the distance covered in the horizontal direction.

Range = U²sin2θ/g

U is the speed of the object

θ is the angle of launch

g is the acceleration due to gravity

If the target is 1000 ft away horizontally, range = 1000ft

θ = 45°

g = 32ft/s²

1000 = U²sin2(45°)/32

32000 =U²sin90°

32000 = U²

U = √32000

U = 125√2 m/s

You must accumulate 790 points to achieve your goal this month. If you work 22 business days this month, how many points must yo
Digiron [165]

Answer:

36 points each day.

Step-by-step explanation:

We have been given that we must accumulate 790 points to achieve our goal this month.            

To find the number of points earned each day, on average, we will divide total number of points achieved in a month by number of business days we worked.

\text{ Points earned each day on average}=\frac{790}{22}

\text{ Points earned each day on average}=35.9090909\approx 35.91    

If we need an integer answer, we can round 35.91 to 36. Therefore, we must  earn 36 points each day, on average to meet our goal.

The surface area of a cone is 43.75 cm2 what is the slant height of the cone ? The base diameter is 5
kramer
<span>The first step in finding the surface area of a cone is to measure the radius of the circle part of the cone. The next step is to find the area of the circle, or base. The area of a circle is 3.14 times the radius squared (<span>πr2</span><span>). Now, you will need to find the area of the cone itself. In order to do this, you must measure the side (slant height) of the cone. Make sure you use the same form of measurement as the radius.

You can now use the measurement of the side to find the area of the cone. The formula for the area of a cone is 3.14 times the radius times the side (</span>πrl<span>).

So the surface area of the cone equals the area of the circle plus the area of the cone and the final formula is given by:</span>

<span>SA = πr2<span> + πrl</span></span><span><span>
