[tex] \qquad \rightarrow \sf p =23 \: ft + 8y[/tex]

Step-by-step explanation:

length × breadth = x² + 5x - 36

let's find, what expression was multiplied by what expression to give that result.

first we see, we have a pure x² term.

so, both start with (x + ...) or (x - ...).

then we see the last (constant) term -36.

so, we have a

(x + a)(x - b)

situation.

36 is the product of

6×6

9×4

12×3

18×2

the term +5x tells us that the difference between a and b must be 5. and a as the positive number must be bigger to give us the "+" (the multiplication contains "... + ax - bx ...").

and that means a = +9, b = -4

so, the original area calculation was

(x + 9)(x - 4) = x² + 5x - 36

when we decrease both factors by 2, we get

(x + 9 - 2)(x - 4 - 2) = (x + 7)(x - 6) = x² + x - 42

that is the new area of the rectangle.

Answer:

[tex]f^{-1} (x)=-\frac{x}{2} +\frac{5}{2}[/tex]

Step-by-step explanation:

To find the inverse, interchange the variables and solve for y.

Replace x and y,  to find inverse function f , and compute the resulting equation for x.

there will be more than one inverse if the elementary function is not one-to-one.

So, exchange the variable: [tex]y=5-2x[/tex] becomes [tex]x=5-2y[/tex]

Now, solve the equation: [tex]x=5-2y[/tex] for y

[tex]y=\frac{5}{2} -\frac{x}{2}[/tex]

Answer:

Step-by-step explanation:

m = -4 ; (x₁ , y₁) = (2, -7)

Point slope form: y - y₁ = m(x - x₁)

y - [-7] = (-4)(x - 2)

y + 7  =(-4)(x - 2)

Using it's concept, it is found that the mean of the data-set is of [tex]\frac{3}{4}[/tex].

The mean of a data-set is given by the sum of all observations in the data-set divided by the number of observations.

In this problem, the 4 observations are given by:

[tex]\left{\frac{1}{2}, \frac{1}{3}, \frac{2}{3}, 1\frac{1}{2} = 1 + \frac{1}{2} = \frac{3}{2}\right}[/tex]

Hence, the mean is given as follows:

[tex]M = \frac{\frac{1}{2} + \frac{1}{3} + \frac{2}{3} + \frac{3}{2}}{4} = \frac{\frac{3 + 2 + 4 + 9}{6}}{4} = \frac{18}{24} = \frac{3}{4}[/tex]

The mean of the data-set is of [tex]\frac{3}{4}[/tex].

Step-by-step explanation:

Make 3x+2y=7 to slope intercept form. y = mx + b

So subtract 3x from both sides to get 2y= -3x + 7

Then divide by 2 on both sides to get y = -3x/2 + 7/2

The slope is -3/2 and the y-intercept is 7/2

The surface area of the pyramid will be 224 square millimeters. The graph is labeled below.

The quantity area demonstrates the amount of a sector on a planar or hemispherical cup. Surface area refers to the area of an open surface or the border of a multi-object, whereas the area of a plane region or plane field refers to the area of a form or planar material.

The surface area of the pyramid is given as,

A = 4 (Area of triangle) + Base area

A = 4 x (1/2 x 10 x 8) + 8 x 8

A = 160 + 64

A = 224 square millimeters

Answer with Step-by-step explanation:

you basically have to prove similarity, then use that to prove the two angles CDE & DAB are equal. You can prove similarity with AA, SSS, or SAS.

Answer:

Y = city C - city D = 2.24 ft

2.24 ft / (1.6 ft / 250 mi) = 350 mi  distance between C and D

Note: 250 mi / 1.6 ft = 156.25 mi / ft

156.25 mi / ft * 2.24 ft = 350 mi
