The radius’s length is one-half the length of the diameter.
The volume of the sphere is StartFraction 16,384 Over 3 EndFraction pi inches cubed.
The diameter’s length is one-half the length of the radius.
Answer:
The sphere has a diameter of 32 in. CORRECT: the diameter of a sphere doubles its radio, so if the radio equals 16,the diameter measures the double, in this case, 32.The radius' lenght is one half the length of the diameter. CORRECT: , by definition, the diameter is the maximum distance between two opposite points on the surface of the sphere, and its lenght equals twice the radius because the radius is the distance between the center of the sphere and any point of the frontier of the sphere (then, one colud imagine that the distance between two opposite points in a sphere can be united by two radius, or a diameter).The volume (V) of a sphere can be calculated as [tex]\frac{4\pi r^3}{3}[/tex], where r is the radio.

At a local fitness center, members pay a $12 membership fee and $3 for each aerobics class. Nonmembers pay $4 for each aerobics class. For what number of aerobics classes will the cost for members and nonmembers be the same?
For 12 number of aerobics classes, cost for members and nonmembers is same
Solution:
Let "x" be the number of aerobic classes
At a local fitness center, members pay a $12 membership fee and $3 for each aerobics class
Therefore,
Members pay = 12 + 3(number of classes)
Members pay = 12 + 3x ------- eqn 1
Nonmembers pay $4 for each aerobics class
Nonmembers pay = 4x ------- eqn 2
For cost for members and nonmembers be the same, eqn 1 must be equal to eqn 2,
12 + 3x = 4x
4x - 3x = 12
x = 12
Thus for 12 number of aerobics classes, the cost for members and nonmembers will be same

Graph the line that has a slope of 1/9 and includes the point (0,8)
Answer:
Step-by-step explanation:
y = mx + b
slope(m) = 1/9
y int (b) = 8.....or (0,8)
y = 1/9x + 8.....this is ur equation
ur x intercept is : (can be found by subbing in 0 for y
0 = 1/9x + 8
-1/9x = 8
x = 8 * -9
x = - 72....or (-72,0)
The equation of line is y = ( 1/9 )x + 8
What is an Equation of a line?
The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one

e^2x + 3e^x - 18 = 0
Solving e²ˣ + 3eˣ- 18 = 0 involves substituting y = ex to transform it into a quadratic equation. Solving this quadratic equation yields a valid solution, y = 3, leading to x = ln(3). Therefore, the solution is x = ln(3).
To solve the equation e²ˣ + 3eˣ- 18, we perform a substitution to convert it into a quadratic form.
Let y =eˣ. Then the equation becomes:
y² + 3y - 18 = 0.This quadratic equation can be solved using the quadratic formula:This gives us two solutions for y:
y = 3 and y = -6.Since y = eˣ, and eˣ must be positive:
y = -6 is not valid. Thus, y = 3.Finally, solve for x:
eˣ = 3 ⟹ x = ln(3).Therefore, the solution to the equation e²ˣ + 3eˣ- 18 = 0 is x = ln(3).

Suppose that a code consists of 5 digits, none of which is repeated. ( A digit is one of the 10 numbers 0,1,2,3,4,5,6,7,8,9.) How many codes are possible?
Answer:
30240
Step-by-step explanation:
There are two primary ways to approach this problem - the logical and the mathematical.
The logical way is very simple:
Since you know that there are 5 digits and each must be different, start with the first digit and work your way up.
The first digit can be any of 10 digits (0–9).
However, the second digit can be any of only 9 digits as 1 digit has already been used and cannot be repeated.
Similarly, applying the same logic, there are only 8 options for the third digit, 7 for the fourth digit, and 6 for the fifth and final digit.
Now, multiply all these numbers together to get the total number of configurations like so:
10⋅9⋅8⋅7⋅6=30240
The more mathematically inclined way requires the use of a special formula. Since in this particular scenario, the order of the numbers matter, we can use the Permutation Formula:
P(n,r)=n!(n−r)!
where n is the number of numbers in the set and r
is the subset.
Since there are 10 digits to choose from, we can assume that n=10
.
Similarly, since there are 5 numbers that need to be chosen out of the ten, we can assume that r=5
.
Now, plug these values into the formula and solve:
=10!(10−5)!
=10!5!
=10⋅9⋅8⋅7⋅6
=30240

A hammer thrower is competing in a track and field meet. He rotates exactly 5 times in 2π seconds, and the motion of his hammer is represented by a sine function.
Which function rule could model this situation?
f(x)=5 sin x
f(x)= sin(5x)
f(x)=5π sin x
f(x)= sin(1/5x)
Answer:
Therefore the correct option is sin(5x).
Step-by-step explanation:
i) The hammer thrower rotates exactly 5 times in 2[tex]\pi[/tex] seconds.
Therefore one rotation is completed in [tex]\frac{2\pi }{5}[/tex] seconds.
ii) Since the motion of the hammer is represented by a sine function therefore
one rotation is considered to be one full cycle and the time period of that cycle
is given in equation i) and it is T = [tex]\frac{2\pi }{5}[/tex] seconds.
iii) the equation of a sine function is given by sin(2[tex]\pi[/tex][tex]\frac{1}{T}[/tex]) which in this case would
be sin(2[tex]\pi[/tex] × [tex]\frac{1}{\frac{2\pi }{5}}[/tex] × x) = sin(5x)
iv) Therefore the answer is sin(5x)
Which of the following equations represents a line that is parallel to y = 3x +2
and passes through the point, (1, 6)?
O A. y = 3x +6
O B. y = 3x +9
O c. y=-3x+2
O D. y = 3x+3
The correct equation of the new line parallel to y = 3x + 2 and passing through (1, 6) is y = 3x + 3.
Explanation:To find the equation of the line that is parallel to the given line y = 3x + 2 and passes through the point (1, 6), we first need to acknowledge that parallel lines have the same slope.
Therefore, the slope of the new line will also be 3. We can use the point-slope form of the equation y - y1 = m(x - x1) to find the equation. Substituting the given point into the equation, we get y - 6 = 3(x - 1).
Simplifying the equation, we find y = 3x + 3. So, the equation of the line that is parallel to the original line and passes through the given point is y = 3x + 3.
When Elmer empties his bank, he found 17 pennies, 4 nickels, 5 dimes, and 2 quarters. What was the value of the coins in his bank?
Elmer's bank contained coins totaling $1.37, calculated by summing the value of each type of coin separately.
Explanation:To find the total value of the coins in Elmer's bank, we need to calculate the value of each type of coin separately and then sum them up. The value of coins is counted based on their denomination, with pennies being worth 1 cent, nickels 5 cents, dimes 10 cents, and quarters 25 cents.
Pennies: 17 pennies × 1 cent = 17 centsNickels: 4 nickels × 5 cents = 20 centsDimes: 5 dimes × 10 cents = 50 centsQuarters: 2 quarters × 25 cents = 50 centsAdding these amounts gives us a total value of 17 + 20 + 50 + 50 = 137 cents. Therefore, the value of the coins in Elmer's bank is $1.37.
The value of the coins in Elmer's bank is $2.17.
17 pennies = $0.17
4 nickels = $0.20
5 dimes = $0.50
2 quarters = $0.50
Adding these amounts together: $0.17 + $0.20 + $0.50 + $0.50 = $2.17.

The variable x represents the number of long sleeve shirts Nancy bought and the variable y represents the number of short sleeve shirts she bought.
Nancy bought 531 shirts for her business. She bought 2 times as many short sleeve shirts as long sleeve shirts.
How many of each type of shirt did she buy?
Final answer:
Nancy bought 177 long sleeve shirts and 354 short sleeve shirts for her business by solving a system of linear equations based on the provided constraints that she bought a total of 531 shirts and twice as many short sleeve shirts as long sleeve shirts.
Explanation:
The student's question involves solving a system of linear equations to find out how many of each type of shirt Nancy bought for her business. Following the given relationships between long sleeve shirts (x) and short sleeve shirts (y), we understand that Nancy bought a total of 531 shirts and that she bought twice as many short sleeve shirts as long sleeve shirts. The two equations that can represent this scenario are:
Equation 1: x + y = 531
Equation 2: y = 2x
To solve this system, we substitute Equation 2 into Equation 1 to get:
x + 2x = 531
Which simplifies to:
3x = 531
Dividing both sides by 3, we find that:
x = 531 / 3 = 177
Using the value of x to find y from Equation 2, we get:
y = 2 * 177 = 35
Therefore, Nancy bought 177 long sleeve shirts and 354 short sleeve shirts.
