Answer:

The dime hits the ground after 8 sec.

Step-by-step explanation:

Set h(t) = -16t^2 + h(0) equal to 0:  -16t^2 + 1,024 ft = 0, or:

16t^2 = 1,024 ft, or:

 t^2 =  64 ft^2

Then t = +8 sec

The dime hits the ground after 8 sec.

Okay so all you have to do is add all of them together. Which I got 46. But then you need that question mark one. Use 17 cause that’s the length of the other side and subtract it by 5 because that’s how much less the other side is so 12. Add 12 to 46 and you get 58.

<span>Using the Triangle Inequality Theorem

</span><span>The sum of two side lengths of a triangle is always greater than the third side
</span>
first one: 6, 22 , 10
6 + 22   > 10 :  yes
22 + 10 > 6   :  yes
6 + 10 > 22   :  No because 16 < 22
These 3 lengths could NOT be lengths of sides of a triangle

second one: 8 , 15 , 22
8 + 15   > 22 :  yes
15 + 22 > 8   :  yes
8 + 22 > 15   :  yes
These 3 lengths could  be lengths of sides of a triangle

Step-by-step explanation:

Simplify the following:

-8×3 a^2 b^4 b^3

Hint: | Combine products of like terms.

3 a^2 b^4 (-8) b^3 = 3 a^2 b^(4 + 3) (-8):

-8×3 a^2 b^(4 + 3)

Hint: | Evaluate 4 + 3.

4 + 3 = 7:

-8×3 a^2 b^7

Hint: | Multiply 3 and -8 together.

3 (-8) = -24:

Answer: -24 a^2 b^7

A model of a volcano has a height of 12 in. , and a diameter of 12 in. What is the approximate volume of the model? Use 3. 14 to
jenyasd209 [6]

The approximate volume of the model will be

v=452.33 inch^{2}

<h3 /><h3>What is the approximate volume of the model? </h3>

It is given that

Height of the volcano =12 inch

Diameter of the volcano= 12inch=r=6inch

So the volume of the model will be =

=\dfrac{1}{3\\} \pi \times r^{2} \times h

= \dfrac{1}{3} \pi \times (6)^{2} \times 12

v=452.33inch^{2}

Thus the approximate volume of the model will be  v=452.33 inch^{2}

To know more about the volume of the cone follow
