The perimeter of a quadrilateral (four-sides polygon) is 50 inches. The longest side is three times as long as the shortest side

kkurt [141]

The side lengths of quadrilateral are 21 inches; 11 inches; 11 inches; 7 inches.

<u>SOLUTION:</u>

Given, the perimeter of a quadrilateral (four-side polygon) is 50 inches.

Let the length of shortest side be n inches. The longest side is three times as long as the shortest side.

That is, length of largest side = 3n inches

The other two sides are equally long and are 4 inches longer than the shortest side.

Then, length of remaining two sides = 4 + n inches

We have to find the length of all four sides.

Now, we know that, perimeter = 50 inches

$\begin{array}{l}{\rightarrow \text { Sum of all sides }=50} \\\\ {\rightarrow n+3 n+n+4+n+4=50} \\\\ {\rightarrow n+3 n+n+n=50-4-4} \\\\ {\rightarrow 6 n=42} \\\\ {\rightarrow n=7}\end{array}$

So, length of sides will be,

$7 \text { inches; } 3\times7=21 \text { inches; } 7+4=11 \text { inches; } 7+4=11 \text { inches. }$

What is the yintercept of the graph of the equation y = 2(4*)?

uranmaximum [27]

Answer:

$\boxed {\boxed {\sf C. \ (0,2)}}$

Step-by-step explanation:

The y-intercept of a graph occurs when the function cross the y or vertical axis. This is also where x is equal to 0.

Therefore, we can substitute 0 in for x and solve for y.

$y= 2(4^x)$

$y= 2(4^0)$

Solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, Subtraction.

Solve the exponent. Any number raised to the power of 0 is equal to 1.

$y= 2(1)$

Multiply.

$y=2$

The y-intercept is 2. So, when x=0, y=2.

Coordinate points are written as (x, y). The y-intercept is <u>(0,2).</u>

The side s of a square carpet is measured at 5 ft. Estimate using the Linear Approximation the maximum error in the area A of th

KonstantinChe [14]

Answer:

$0.333 ft^2$

Step-by-step explanation:

We are given that

Side of square carpet,s=5 ft

$\Delta s=0.4 in=\frac{0.4}{12}ft$

1 foot=12 in

We have to find the maximum error in the area of the carpet by using the linear approximation .

Area of square,A= $(side)^2=s^2$

$dA=2sds$

Substitute the values

$dA=2\times 5\times \frac{0.4}{12}$

$dA=0.333ft^2$

Hence, the maximum error in the area of the carpet= $0.333 ft^2$
