First find slope
(Y2-y1)/(x2-x1)
(-3-(-1))/(-6-9) = -2/-15 = 2/15
Point slope: y-y1 = m(x-x1)
Solution: y + 1 = 2/15(x - 9)

A contemporary building has a window in the shape of a parallelogram with a base of 90 in and an adjacent side of 40 in. How man

BaLLatris [955]

260 inches of trim are needed to surround the window.

<h3 /><h3>What is the surface area?</h3>

The total land area of all the faces of a three-dimensional object is its surface area. When we wish to wrap something in real life, we employ the notion of surface areas of distinct things.

Actually, all we need is a trim that is the same size as our window and equal to the parallelogram's circumference, which is

The sum of the side is;

⇒Length of lower side + Length of the upper side

⇒ 90+90

⇒180 inches

The sum of adjacent sides;

Sum of adjacent sides = 40+40

Sum of adjacent sides = 80 inches

The length you should trim is needed to surround the window is found as;

⇒ 180 inches + 80 inches

⇒260 inches

Hence,260 inches of trim are needed to surround the window.

P=2a+b+c solve for c

Harman [31]

P = 2a + b + c

Subtract 2a + b on both sides

c = P - (2a+b)
c = P - 2a - b

Answer:

82.96

Step-by-step explanation:

area of box:

A = L^2 = (14 in.)^2 = 196 in.^2

area of pizza:

A = (pi)r^2 = 3.14 * (6 in.)^2 = 113.04 in.^2

Empty area:

196 in.^2 - 113.04 in.^2 = 82.96 in.^2

Which scatterplot has a correlation coefficient closest to r = 1?

qwelly [4]

Answer:

The scatter diagram that contains the correlation coefficient closest to r = 1 is the first one shown in the attached images.

Step-by-step explanation:

The correlation coefficient "r" measures how much two variables x and y are related. When the variables are highly related, the value of r is closer to one and the points contained in the scatter diagrams are assimilated more and more to a line. When the value of r is positive the relation is crescent and therefore the slope of the line drawn by the points in the diagram has a positive slope

Therefore, to answer this question, one must search among the attached images for the dispersion diagram in which the points resemble a straight line with a positive slope.

The scatter diagram that meets the requirements mentioned is the first one that appears in the attached images
