This figure shows the nose cone of a rocket used for launching satellites. The nose cone houses the satellite until the satellite is placed in orbit. What is the volume of the nose cone?45 cubic feet
60 cubic feet
90 cubic feet
180 cubic feet

Answers

Answer 1

Answer:

see the attached figure to better understand the problem

we know that

The volume of the cone is equal to

$V=(1)/(3) \pi r^(2) h$

in this problem

$r=(6)/(2) =3\ ft\n \n h=15\ ft$

Substitute the values in the formula above

$V=(1)/(3)* \pi* 3^(2)* 15\n \n V=45\pi \ ft^(3)$

therefore

the answer is

The volume of the nose cone is $45\pi \ ft^(3)$

Answer 2

Answer: The formula to get the volume of a cone is
V = (1/3)πr²h
where V is the volume
r is the radius at the base
h is the height

No values are given but simple substitution should give the correct answer.

A ten foot long ladder leans against a wall, with the top of the ladder being eight feet above the ground. What is the approximate angle that the ladder makes with the ground?

Answers

Answer:

The angle that the ladder made with the ground = 53.13010235°

Step-by-step explanation:

The ladder has a length of 10 ft and it leaned against a wall to form a right angle triangle. The height from the top of the ladder to the ground is given as 8 ft. The triangle formed from the illustration can be represented with the picture below.

The angle A is the angle the ladder made with the ground.

Length of ladder = c

height from the top of the ladder to the ground = a

The distance of the foot of the ladder and the wall = b

c = 10 ft

a = 8 ft

Using SOHCAHTOA

sin A = a/c

sin A = 8/10

sin A = 0.8

A = sin-1 0.8

A = 53.13010235°

so we got hypotenuse and opposite side so to find the angle we use the trig function
sin = opposite/hypotenuse
¢=angle
sin¢=8/10
sin¢= 0.8

arcsin¢=arcsin(0.8)
¢= 53.13 degrees

Simplify the expression above

Find -x + 10 less than 0.

0
-x + 10
x - 10

Answers

$-x + 10 \ \textless \ 0$

Transposing the inequation gives:
$-x \ \textless \ -10$

Since we want to get rid of the negatives on both sides, we must flip the sign:
$x \ \textgreater \ 10$

If you transpose the equation to make RHS be 0:
$x - 10 \ \textgreater \ 0$
That seems to satisfy x - 10 (could be wrong though...)

But I'm not exactly clear on what you want as the options above don't seem to give that much context :I
