Marysya12 [62]3 years ago
4 0

Answer:

Step-by-step explanation:

Slope = (Difference of y-coordinates)/(difference of x-coordinates)

= (-4 - 2)/(-1 - 3)

= (-6)/(-4)

= 3/2

A gardener has 520 feet of fencing to fence in a rectangular garden. One side of the garden is bordered by a river and so it doe
Bond [772]

The shortest side is 130 feet, the longest side is 260 feet and the greatest possible area is 33800 square feet

<h3>What dimensions would guarantee that the garden has the greatest possible area?</h3>

The given parameter is

Perimeter, P = 520 feet

Represent the shorter side with x and the longer side with y

One side of the garden is bordered by a river:

So the perimeter is:

P = 2x + y

Substitute P = 520

2x + y = 520

Make y the subject

y = 520 - 2x

The area is

A = xy

Substitute y = 520 - 2x in A = xy

A = x(520 - 2x)

Expand

A = 520x - 2x^2

Differentiate

A' = 520 - 4x

Set to 0

520 - 4x = 0

Rewrite as:

4x= 520

Divide by 4

x= 130

Substitute x= 130 in y = 520 - 2x

y = 520 - 2 *130

Evaluate

y = 260

The area is then calculated as:

A = xy

This gives

A = 130 * 260

Evaluate

A = 33800

Hence, the shortest side is 130 feet, the longest side is 260 feet and the greatest possible area is 33800 square feet

Answer:

A <em> </em><em>and</em><em> </em><em>E</em><em> </em><em>is</em><em> </em><em>true</em><em>. </em><em>BCD</em><em> </em><em>is</em><em> </em><em>False</em>

Step-by-step explanation:

Let convert this into slope intercept form

10y - 200x = 500

10y = 200x + 500

y = 20x + 50

So now let answer these questions,

A is TRUE the slope is the number in front of the x value. It is 20 so a is true.

B is False, Using (0, 500) The equation is wrong

500 = 20(0) + 50 ??

C is false, we have a positive slope so it shifts upward from left to right.

D is false

the slope isn't 200.

E Is true the y intercept is when the x value is 0, what is the y value so plug it in we get

y = 20(0) + 50

It equal 50.

Nutka1998 [239]

Answer:

3.33%

Step-by-step explanation:

Given that :

Final amount A= 320

Principal P = 300

Time (t) = 2 years

Yes, the information is enough to obtain the interest rate :

Using the relation :

A = P(1 + rt)

r = interest rate

320 = 300(1 + r*2)

320 = 300(1 + 2r)

320/300 = 1 + 2r

1.0666666 = 1 + 2r

1.0666666 - 1 = 2r

0.0666666 = 2r

r = 0.0666666 / 2

r = 0.0333333

(0.0333333) * 100% = 3.33%

kakasveta [241]
Use the percent proportion

 21          x
——  = —— 
100        300

to solve :
21 x 300 = 6300
6300 ÷ 100 = 63

Answer = 63 of Elmer’s shells are fossilized snail shells :)

ella [17]

Step-by-step explanation:

\frac{3}{5}  +  \frac{1}{2}  \\  \\  =  \frac{3 \times 2 + 1 \times 5}{5 \times 2}  \\  \\  =  \frac{6 + 5}{10}  \\  \\  =  \frac{11}{10}  \\  \\  = 1 \frac{1}{10}
