Find the volume of the sphere. Either enter an exact answer in terms of pi or use 3.14 for pi and round your final answer to the nearest hundredth.
The radius is 7
Step-by-step explanation:
Volume = 4/3 × [tex]\pi[/tex] r³
Volume = 4/3 × 3.14 × 7 × 7 × 7
Volume = 1436.03 cm³
The volume of the sphere with a radius of 7 units is 457.33π cubic units
Volume of a sphereA sphere is a solid 3-dimensional figure. The volume of a sphere is expressed as:
V = 4/3πr^3
where:
r is the radius of the sphere:
Given the following
r = 7 units
Substitute the given parameters
V = 4/3(π) * 7^3
V = 4/3 * π * 343
V = 1372π/3
V = 457.33π cubic units
Hence the volume of the sphere with a radius of 7 units is 457.33π cubic units

25. In the diagram, CT = 10.
What is the length of AB?
Answer:
The length of AB is 4.33012701892
Step-by-step explanation:
1. You find 10*sin(60 degrees), because sin(60 degrees) = x/CT, and CT = 10. That means that sin(60 degrees) = x/10. You multiply by 10 on both sides, which would mean that x = 10sin(60 degrees) and that AT = 8.66025403784 because x is AT.
2. Then, because the relation between AT and AB and Angle T is sine, you use cosine to find x. If you do that, you find that the equation is sin(30 degrees) = x/8.66025403784. That means that 8.66025403784*sin(30 degrees) = x. If you calculate that, you find that x = 4.33012701892, and AB is x.

Identify the polar coordinates for each value in the table below, discuss the shape and behavior of the graphs, and use this to graph the equation of r=2 cos〖3θ.〗
Symmetry hint: see if the equation is true for the following:
the line θ = 90°: replace (r, θ) with (r, 180° – θ) or (-r, -θ)
the polar axis: replace (r, θ) with (-r, 180° – θ) or (r, -θ)
the pole: replace (r, θ) with (r, 180° + θ) or (-r, θ)
Answer:
we know that
the relationship between the 2-dimensional polar and Cartesian coordinates is
r = √(x² + y²)
Θ = tan⁻¹ (y/x)
so
Part a) (2, −2)---------> this point belong to the IV quadrant
r = √(x² + y²)------ r = √(2² + (-2)²)-----> r=√8
Θ = tan⁻¹ (y/x)---- Θ = tan⁻¹ (2/2)----> 45°
remember that the point belong to the IV quadrant
so
Θ=360-45-----> Θ=315°
the answer part A) is
(r,Θ)=(√8,315°)
Part b) (-1, 3)---------> this point belong to the II quadrant
r = √(x² + y²)------ r = √(-1² + (3)²)-----> r=√10
Θ = tan⁻¹ (y/x)---- Θ = tan⁻¹ (3/1)----> 71.57°
remember that the point belong to the II quadrant
so
Θ=180-71.57-----> Θ=108.43°
the answer part B) is
(r,Θ)=(√10,108.43°)
mark me branlest plz hope it helps
The answers are a) (r,θ) = (√8,315°) and b) (r, θ) = (√10,108.43°).
The relationship between the 2-dimensional polar and Cartesian coordinates is
r = √(x² + y²)
θ = tan⁻¹ (y/x)
so,
A) (2, −2 belongs to the IV quadrant,
r = √(x² + y²)
r = √(2² + (-2)²
r=√8
θ = tan⁻¹ (y/x)
θ = tan⁻¹ (2/2)
= 45°
The point belongs to the IV quadrant,
so,
θ = 360-45
θ = 315°
Therefore,
(r,θ) = (√8,315°)
B) (-1, 3) belong to the II quadrant,
r = √(x² + y²)
r = √(-1² + (3)²)
r = √10
θ = tan⁻¹ (y/x)
θ = tan⁻¹ (3/1)
= 71.57°
The point belongs to the II quadrant ;
so,
θ = 180-71.57
θ = 108.43°
Therefore,
(r, θ) = (√10,108.43°)

Complete Question:
The smallest hummingbird is the Bee hummingbird. It has a mass of about 1 1/2 grams. The mass of a larger type of hummingbird is about 5 times the mass of the Bee hummingbird.
What is the mass of the larger humming bird?
Answer:
7 1/2 grams
Step-by-step explanation:
The mass of Bee humming bird is given in the question as = 1 1/2 grams
Mass of the larger humming bird = 5 times the mass of Bee humming bird
The mass of the larger humming bird is calculated as:
5 × 1 1/2 grams = 5 × 3/2 grams
= 15/2 grams = 7 1/2 grams
Therefore, the mass of the larger humming bird is 7 1/2 grams

2. If a toy rocket is launched vertically upward from ground level with an initial velocity of 128 feet
per second, then its height h after t seconds is given by the equations h(t) = -16° +128t (if air
resistance is neglected).
a. How long will it take for the rocket to return to the ground?
b. After how many seconds will the rocket be 112 feet above the ground?
C. How long will it take the rocket to hit its maximum height?
d. What is the maximum height?
Answer:
a. 8 seconds.b. 1 second and 7 seconds.c. 4 seconds.d. 256 feet.Step-by-step explanation:
The given function is
[tex]h(t) = -16t^{2}+128t[/tex]
The image attached shows the trajectory of the rocket in a height-time graph. Notice that the maxium point reached is (4, 256), which means after 4 seconds, the rocket has a maximum height of 256 feet. (c) and (d)
Additionally, a parabola is symmetrical, which means it takes the same time going up or down, therefore the rocket reaches the ground after 8 seconds. (a)
Now, when the rocket is 112 feet above the ground, we have
[tex]112 = -16t^{2}+128t[/tex]
Where we need to solve for [tex]t[/tex]
[tex]0 = -16t^{2}+128t-112[/tex]
Using a calculator, we have the solutions [tex]x_{1}= 1[/tex] and [tex]x_{2}=7[/tex], which means after 1 second and 7 second, the rocket is 112 feet above the ground. (b)

The line graph shows the number of goals scored
by a team in 18 games.
a) In how many games were zero
goals scored?
Number of games
b) Altogether, how many goals did
the team score in the 18 games?
c)What was the median number
of goals that the
team scored?
Answer:
a) 1 game
b) 41 goals
c) median = 2
Step-by-step explanation:
a)
As we can see in the line graph, where we have the 0 for the number of goals scored, the graph indicates only 1 in the number of games, so we have only 1 game where no goals were scored.
b)
To find the total number of goals scored, we multiply the goals scored by the number of games for that score, and then sum them all:
total goals = 1*0 + 4*1 + 5*2 + 6*3 + 1*4 + 1*5 = 41 goals
c)
To find the median, we put all the goals in crescent order, and then find the value in the middle. As we have 18 games, the middle value will be an average of the 9th and 10th terms.
We have 1 number 0, 4 numbers 1 and 5 numbers 2 in the beginning, so for these 10 numbers, the 9th and the 10th are the score 2, so the median is 2.

Please help I’ll give brainliest
Answer:
Option B
Step-by-step explanation:
Given: all the four-digit numbers are formed using the digits 1, 2, 3, and 4 such that no digit is used twice
To find: probability that number chosen lies between 2000 and 3000
Solution:
Probability refers to chances of occurring of some event.
Total number of numbers formed using digits 1, 2, 3, and 4 = [tex]4\times 3\times 2\times 1=24[/tex]
Numbers between 2000 and 3000 start with 2. So, first digit is fixed as 2. For remaining three digits, possibilities are 4, 3, 1
So, total number of numbers lie between 2000 and 3000 = [tex]3\times 2\times 1=6[/tex]
Probability that number chosen lies between 2000 and 3000 = total number of numbers lie between 2000 and 3000/Total number of numbers formed using digits 1, 2, 3, and 4 = 6/24 = 1/4
In percentage form, Probability that number chosen lies between 2000 and 3000 = [tex]\frac{1}{4}(100)=25\%[/tex]
Probability that a four digit number formed from 1,2,3,4 is between 2000 & 3000 = 25%
Calculation of Probability
Total number of four digit numbers that can be formed by digits 1,2,3,4 (without repetition)
Possible outcomes for first digit = 4
Possible outcomes for second digit = 3
Possible outcomes for third digit = 2
Possible outcomes for fourth digit = 1
So, total ways in which mentioned 4 digit number can be formed = 4 x 3 x 2 x 1 = 24 ways
When number is between 2000 & 3000, it starts from digit 2
So, possible outcome for first digit = only 1 ( ie digit 2)
Possible outcomes for second digit = 3
Possible outcomes for third digit = 2
Possible outcomes for fourth digit = 1
So, total ways in which 4 digit number starting from digit '2' can be formed = 1 x 3 x 2 x 1 = 6 ways
Probability = Favourable outcomes / Total outcomes
6 / 24 = 0.25 = 25%

A. 5.0x[tex]10^{14}[/tex] seconds

C. 2.0x[tex]10^{-53}[/tex] seconds
