The elevation of an airplane changes by-420 feet in 12 seconds. What is the change in the airplane's elevation each second?
Answer:
-35 feet each second
Step-by-step explanation:
Divide -420 by 12:
-420/12
= -35
So, the change in the plane' elevation is -35 feet each second
Answer:
-35 feet per second
-420/12 = -35

if f(x) = x^2, and
g(x) = x-1, then
g(f(x))=x^__+__
Answer:
(x^2) + (-1)
Step-by-step explanation:
the equation f(x) BECOMES x in the g(x)
x-1
(x^2) -1
Answer:
g(f(x)) = x^2 + (-1)
Step-by-step explanation:
f(x) = x^2
g(x) = x - 1
Therefore, for g(f(x)), we need to substitute the value of x in f(x) in g(x).
Therefore,
g(x) = (x^2) - 1
= (x^2) + (-1)

Answer:
[tex]-\frac{21}{10}[/tex] or [tex]-2.1[/tex] (they're the same)

The formula for the volume of a cylinder is v=piR^2h where v is the volume, R is the radius, and h is the height solve the formula for R and then use it to answer the question.
A cylindrical bucket contains 615 cubic inches of water. The height of the water is 4 inches
What is the radius of the bucket, to the nearest whole number? Use 3.14 for pi
Answer: Its 6
Step-by-step explanation: The answer is 5.99894 then you round it to 6.
The radius of the bucket, to the nearest whole number, is 7 inches.
So, option A. is correct.
Here, we have,
To solve the formula v = πR²h for R, we can rearrange the equation as follows:
v = πR²h
R² = v / (πh)
R = √(v / (πh))
Given that the volume v is 615 cubic inches and the height h is 4 inches, we can substitute these values into the equation:
R = √(615 / (3.14 * 4))
Calculating the value, we have:
R ≈ √(48.98)
R ≈ 7
Therefore, the radius of the bucket, to the nearest whole number, is 7 inches.
Hence, So, option A. is correct.

You are saving to buy a new phone you have $150 in your bank account and can save $55 each week assuming you don’t spend any money write an expression to represent the amount of money you will have in your bank account after W weeks
Answer:
150+55w
Step-by-step explanation:
150+55w
150 never changes
(55)(w), 55 changes depending on number of weeks
Answer:
The expression is: 150 + 55W
Step-by-step explanation:
amount already in your a/c = $150
Amount saved per week = $55
Number of weeks to save for is W
Amount saved in W weeks is $55W
Total amount saved in W weeks is $150 + $55W
Ignoring the symbols, the expression is 150+55W

Solve for x:
X- 6 = -3x + 22
Answer:
Your answer is x=7
Step-by-step explanation:
[tex]x - 6 = -3x + 22[/tex] add 6 to both sides
[tex]x - 6(+6) = -3x + 22(+6)[/tex] cross out -6(+6) and add 22+6=28
[tex]x = -3x + 28[/tex] add 3x on both sides
[tex]x (+3x) = (+3x)-3x + 28[/tex] x+3x=4x and cross out (+3x)-3x
[tex]4x = 28[/tex] divide 4 on both sides
[tex]\frac{4x}{4} = \frac{28}{4}[/tex] cross out 4 leave x and divide 28 and 4 =7

what is the slope of the line that passes through the points (5,10) and (11,-12)
Answer:m=-11/3
Step-by-step explanation:
Answer:
-11/3
Step-by-step explanation:
We have two points so we can find the slope using the slope formula
m = ( y2-y1)/(x2-x1)
= ( -12-10)/(11 -5)
= -22/6
= -11/3
2. -5x – y = 7
I need help to solve for y
Answer:
y= -7 - 5x
Step-by-step explanation:
Move all of the terms that dont contain y to the right side and then solve it.
Hope this helps.
The value of the given equation in the form of y is y= -7 - 5x.
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 equation is -5x – y = 7. The value of the expression for the value of y will be calculated as below:-
-5x – y = 7
-y = 7 + 5x
y = -7 - 5x
Therefore, the value of the given equation in the form of y is y= -7 - 5x.

1. A point is named or labeled using? 2. Three distinct points are collinear if ? 3. Three distinct points are coplanar if ? PLZ HELP
Answer:
1) A point P is named or labeled by using a coordinate pair, where the regular notation is:
P = (x, y).
Where x and y are the horizontal and vertical components.
2) Three distinct points are collinear if exists a line that passes through the 3 points.
3) Three distinct points are complanar if they are not collinear, this means that:
We can have two colinear points (so one line connects them) and another point outside that line.
Then the set of 3 points is coplanar.
