The total distance from Duncan's start on the diving board to his lowest point beneath the surface of the pool will be 12 feet.
What is an expression?Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Given that Duncan is excited to begin diving lessons. He starts on the diving board, 5 feet above the surface of the pool. Then, Duncan dives off the board and ends up 7 feet below the surface of the pool.
Distance = 7 + 5
Distance = 12 feet
Therefore, the total distance from Duncan's start on the diving board to his lowest point beneath the surface of the pool will be 12 feet.

HELP WILL GIVE BRAINLIEST!!Aditi has $50.00 in her wallet. She buys a shirt for $12.00 and also wants to buy some bracelets that are on sale for $0.60 each. The inequality below relates x, the number of bracelets she can buy, with her shirt purchase and the money in her wallet.
12 + 0.60 x less-than-or-equal-to 50
What is the greatest number of bracelets she could buy?
Answer:
The greatest number of bracelets she can buy is 63.
Step-by-step explanation:
12 + 0.60x ≤ 50
Since we already have the inequality, we have to start picking random numbers(until there are no more solutions):1.) 12 + 0.60(63) ≤ 50
12 + 37.8 ≤ 50
49.8 ≤ 50
Since 49.8 ≤ 50 is always true, there are infinitely many solutions.
Now we know that she can buy 63 bracelets, we have to figure out if she can buy more:2.) 12 + 0.60(64) ≤ 50
12 + 38.4 ≤ 50
50.4 ≤ 50
Since 50.4 ≤ 50 is false, there is no solution.

63

What is the equation of a sine function with an amplitude of 2 and a period of 4
Answer: C
Step-by-step explanation:
For this problem, we need to know the standard form of a sine function and the meaning of each part.
Standard form: [tex]y=asin[b(x-h)]+k[/tex]
a=amplitude
b=period
h=phase shift
k=vertical replacement/shifting
Now that we know the standard form and the components, we know that we can forget about k and plug in 0 for h. This would leave us with [tex]y=asin[b(x)][/tex]. We know that the amplitude is 2, therefore, a=2. To find the period, you divide 2π by the given period. [tex]\frac{2\pi }{b} =\frac{2\pi }{4\pi } =\frac{2}{4} =\frac{1}{2}[/tex], therefore, b=1/2.
[tex]y=asin[b(x)][/tex] [plug in a=2]
[tex]y=2sin[b(x)][/tex] [plug in b=1/2]
[tex]y=2sin(\frac{1}{2}x)[/tex]
Therefore, C is the correct answer.
The function is expressed by a formula y=0.1x+5. Find the value of the function if the variable is equal to 10; 50; 120.
Answer:
f(x) = 10: [tex]\large\boxed{6}[/tex]
f(x) = 50: [tex]\large\boxed{10}[/tex]
f(x) = 120: [tex]\large\boxed{17}[/tex]
Step-by-step explanation:
Write out the whole function using given information
f(x) = [10, 50, or 120]
Domain/y = 0.1x + 5
Substitute the possible values for x into the domain equation and solve
f(x) = 10: 0.1(10) + 5 = 1 + 5 = 6
f(x) = 50: 0.1(50) + 5 = 5 + 5 = 10
f(x) = 120: 0.1(120) + 5 = 12 + 5 = 17
Final answers:
f(x) = 10: [tex]\large\boxed{6}[/tex]
f(x) = 50: [tex]\large\boxed{10}[/tex]
f(x) = 120: [tex]\large\boxed{17}[/tex]

7. In name the bisected angles 1 and 2. If is 4x 3y, can be determined in terms of x and y? If so, state in terms of x+ y expression and explain your reasoning.
Answer:since there is no diagram i will answer to the best of my ability.
Step-by-step explanation:
If an angle is bisected then it is divided into 2 equal angles which i think they are naming 4x and 3y. In this case, 4x=3y. Solving for x, we get x= (3y)/4. Solving for y we get y= (4x)/3. Now if we substitute (4x)/3 for y in the equation x= (3y)/4 then x= (3(4x)/3)/4 = 4x/4=× so then we can say x÷y = measure of original angle that was bisected. Or znother way it can be said is x+y = 2x or x+ y =2y.
