Elena plays the piano for 30 minutes each practice day.
The total number of minutes p that Elena practiced last week is a function of n, the number of practice days.
What is the domain for this function?
What is the range of this function?
Answer:
Step-by-step explanation:
f(n)=30n
domain all real numbers
range all real numbers
I think.
Domain is {0, 1, 2, 3, ...} and range is {0, 30, 60, 90, ...} for function p=30n.
What is a function?A relation is a function if it has only One y-value for each x-value.
The function that relates the total number of minutes practiced, p, to the number of practice days, n, is given by:
p = 30n
where 30 is the number of minutes Elena practices each day.
Since we cannot have negative practice days, the domain of the function is the set of non-negative integers:
Domain: {0, 1, 2, 3, ...}
The range of this function is the set of all possible values of p that can be obtained by plugging in values of n from the domain.
In this case, since the function only outputs non-negative values, the range is the set of non-negative integers:
Range: {0, 30, 60, 90, ...}
Hence, Domain is {0, 1, 2, 3, ...} and range is {0, 30, 60, 90, ...} for function p=30n.

Step-by-step explanation:
the main equation would be
210+3x>288
first I divided 210 by 3 to see how many mugs he has sold first. Then I got an answer of 70 mugs sold. after that i subtracted 210 from 288 and got 78. After this I divided 78 by 3 to get a count of how many mugs Ronny needs to sell. so The total amount of mugs Ronny needs to sell to reach his goal of 288$ is 96. But he has already sold 70 so he needs to sell 26 more mugs.

A square rug has an inner square in the center. The side length of the inner square is x inches and the width of the outer region is 2 in. What is the area of the outer part of the rug?
Answer:
so Area of Outer part = 8x + 16 square inches
Step-by-step explanation:
2 squares.
inner square dimension is x inches by x inches.
width of outer region= 2inches.
We want the area of the border around the inner square.
so
Area of border = B = Area of Large - Area of Inner
B = (x+4)^2 - x^2
B = x^2 + 8x + 16 - x^2
B = 8x + 16 square inches
so Area of Outer part = 8x + 16 square inches

How do you solve a y=mx+b equation if x is unkown?
example -
y = 1.29x+2
How do I solve that? Please make sure to explain :) thanks!
Answer
Y= 2 x= -0.645
Step-by-step explanation:
you basically plug 0 into x and y
y=1.29(0)+ 2
y=2
0=1.29x+ 2
Answer:
Okay so "y = mx+b is a linear equation that represents a line on a graph; m represents the slope of the line and b is the y-intercept (The y-intercept of this line is the value of y at the point where the line crosses the y axis.)
In y = 1.29x+2, 1.29 is equal to m, so that is your slope.
The 2 is equal to the b so your y-intercept is 2.
Here's a graph to better understand it :)

Myra's sailboat has a small glass window that allows light to enter the cabin. The window is shaped like a rectangle with semicircles on both ends. The dimensions are shown in the diagram below.
Which measurement is closest to the area of the glass window in square inches? Use 3.14 for pi?
A. 3 square inches
B. 153.48 square inches
C. 103.24 square inches
D. 253.96 square inches
Answer:
C.)
Step-by-step explanation:
Add the area if the rectangle, to the area of the two semi-circles.
Area of Rectangle: L: 6[tex]\frac{5}{8}[/tex] in times W: 8 in = 53 in
Area of Semi-circle: [tex]\frac{1}{2}[/tex](πr2): [tex]\frac{1}{2}[/tex](π(4)2) = 25.13
(r is always half of diameter (d) so r=4)
53 + 25.13 + 25.13 = 103.26

as the summation of all angles in a triangle must be 180
∠H = 180 - (130 +20)
= 180-150
=30
as the straight line has an angle of 180
∠G= 180 - 130
= 50
since that
∠f = 180- (50+60)
=180- 110
=70
