For a science project, Joseph launches a model rocket. The function "h(s)=-3s^2+6s+45 represents the height in feet of the rocket after s seconds. It will take the rocket ___ second(s) to reach its maximum height. A - 1 B - 3 C - 5 D - 45 E - 48

Answers

Answer 1

Answer:

t = 1 s to reach its maximum height.

Step-by-step explanation:

The function that represents the height of the rocket after s seconds is given by :

[tex]h(s)=-3s^2+6s+45[/tex] ...(1)

For maximum height,

[tex]h'(s)=0\\\\-6s+6=0\\\\s=1[/tex]

It is the time the rocket will take. So, the ball will take 1 second to reach its maximum height.

Find the measure of arc YX in the inscribed angle C in the circle below

Answers

Answer:

Arc YX = 104°

Step-by-step explanation:

Arc YX + Arc YZ + Arc XZ = 360° (full circle = 360°)

Substitute

Arc YX + 110° + 146° = 360°

Arc YX + 256° = 360°

Arc YX = 360° - 256°

Arc YX = 104°

The figure is made up of a cylinder and 2 cones. What is the volume of the composite figure? Use 3.14 for Pi. Round to the nearest hundredth.

Please help!!!!!
A cylinder and 2 cones. All have a radius of 2 millimeters. The cones have heights of 4 millimeters and 2 millimeters, and the cylinder has a height of 5 millimeters.

Recall the formulas V = B h and V = one-third B h

Answer——————- millimeters cubed

Answers

Answer:

96.29  mm^3

Step-by-step explanation:

Cylinder

V = pi r^2 h

V = 3.14 ( 2)^2 ( 5)

V = 3.14 *4*5

V =62.8 mm^3

Cone

V = 1/3 pi r^2 h

V = 1/3 (3.14) 2^2 ( 4)

V =1/3 (3.14) 4*4

V =16.746666666 mm^3

There are 2 cones so multiply by 2

Both cones = 33.493333333333 mm ^3

Add the cones and the cylinder together

62.8+33.493333333 =96.293333333

Tucker's Road Paving Company used 646.5 tons of cement to pave 4 miles of roadway. To the nearest hundredth of a ton, how much cement, on average, did the company use per mile?

Answers

Answer:

161.63 tons

Step-by-step explanation:

Cement used per mile = total cement used / total miles

646.5 tons / 4 = 161.625 tons

161.63 tons to the nearest hundredth

the hundredth is the second number after the decimal place. To convert to the nearest hundredth, look at the number after the hundredth (the thousandth). If the number is greater or equal to 5, add 1 to the hundredth figure. If this is not the case, add zero

the thousandth term is 5, so 1 would be added to 2

Find the cosine of ∠G (Must give explanation)

also why does my calculator say its undefined if I do the cos invert of (85/77) ??

cos^-1(85/77) = undefined ?? why

Answers

Answer:

[tex]\displaystyle \cos (G)=\frac{36}{85}[/tex]

Step-by-step explanation:

Recall that cosine is the ratio of the adjacent side to the hypotenuse:

[tex]\displaystyle \cos(G)=\frac{\text{adjacent}}{\text{hypotenuse}}[/tex]

The hypotenuse is always the side opposite to the right angle. In this case, it is

85.

The adjacent side to G is 36.

Therefore:

[tex]\displaystyle \cos (G)=\frac{36}{85}[/tex]

For your other question, remember that in a right triangle, cosine is the ratio of the adjacent side to the hypotenuse.

As you know, the hypotenuse is always the longest side in a right triangle.

Therefore, the ratio of the adjacent side to the hypotenuse will never be greater than 1.

Since 85/77 is greater than 1, it is undefined.

The same applies to sine as well.

400 + 576 = Hypotenuse²

976 = Hypotenuse²

[tex]\sqrt{976}[/tex] = Hypotenuse

31.24 = Hypotenuse

Therefore, the measure of the third side would be: 31.24

What are 3 tips to solve quadratic equations using the quadratic formula?

Answers

Answer:

Step-by-step explanation:

I would say the first thing you should always do is graph the quadratic. See where the x intercepts are. If there aren't any, go onto step 2. If there are, make note of them. The quadratic formula will give you the same answer. You can use Desmos to graph the quadratic.The second thing to do is to test what is under the square root (called the discriminate).  If you get something weird like the square root of a minus number, then the graph should have told you that the quadratic does not cross the x axis at all.When you have done those two things, you are ready to use the whole quadratic. Watch out for -b at the beginning. If b is - 4 (for example) the -b will make it 4
