* The proof is "dirty" only in that the theorem "if the midpoints of the diagonals of a quadrilateral are coincident, then that quadrilateral is a parallelogram" is not one usually available to cite in proofs. The "more formal" proof here essentially proves that the quadrilateral is a parallelogram.

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?

Answers

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.

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!

Answers

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 :)

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?

Answers

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

I’m pretty sure it’s C

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)
