whats the formula for area of an rectangle

Answers

Answer:

L (lengh) · W (width)

Step-by-step explanation:

Tp find the area of a rectangle, you always have to multiply the length by the width. You do this because there are individual little array-like squares that make up the area. You could just count the square units, but multiplying is faster.

Answer:

For Perimeter its  2times length + 2times width

and for Area its: length times width

A line has the equation y=x+3
What are the coordinates of the point where the line intersects the y and x axis?

Answers

Answer:

(0, 3 ) and (- 3, 0 )

Step-by-step explanation:

Where the line crosses the y- axis the x- coordinate is zero.

Substitute x = 0 into the equation and solve for y

y = 0 + 3 = 3

Thus the y- intercept is (0, 3 )

Where the line crosses the x- axis the y- coordinate is zero.

Substitute y = 0 into the equation and solve for x

0 = x + 3 ( subtract 3 from both sides )

- 3 = x

Thus the x- intercept is (- 3, 0 )

A) Complete the table of values for y= x^2 - 4x


Answers

Answer:

y = x² - 4x

x = -1 y = 5

x = 0 y = 0

x = 1 y = -3

x = 2 y = - 4

x = 3 y = - 3

x = 4 y = 0

x = 5 y = 5

Hope this helps.

The equivalent values to complete the table are 5, -1, -4 and 0

Given the function according to the table shown:

[tex]y= x^2 - 4x[/tex]

When x = -1

[tex]y= (-1)^2 - 4(-1)\\y=1+4\\y=5[/tex]

When x = 1

[tex]y= (1)^2 - 4(1)\\y=1-4\\y=-3[/tex]

When x = 2

[tex]y= (2)^2 - 4(2)\\y=4-8\\y=-4[/tex]

when x = 4

[tex]y= (4)^2 - 4(4)\\y=16-16\\y=0[/tex]

Hence the equivalent values to complete the table are 5, -1, -4 and 0

3y +19 = 6y+1

Subtract 3y from each side

3y+19-3y = 6y-3y+1

19 = 3y+1

Subtract 1 from each side

19-1 = 3y+1-1

18 = 3y

Divide each side by 3

insert the value of y in the second equation. 5x-7y=16

5x-7(6/7)=16

5x-49\6=16

collect the liketerms together

5x=16+49/6

5x=145/6(divide both sides by 5)

x=29/6

x=45/6

A farmer finds that if she plants 25 trees per acre, each tree will yield 41 bushels of fruit. She estimates that for each additional tree planted per acre, the yield of each tree will decrease by 1 bushel. How many trees should she plant per acre to maximize her harvest?

Answers

Answer:

17

Step-by-step explanation:

Let F be the number of fruit per acre  

F = (25 + x) × (41 - x)  

F=1025 -25x + 41x -x²

F=-x²+16x+1025

The maximum yield is at the maximum of that expression, which is at

[tex]x=-\frac{b}{2a} =>-\frac{16}{-2\times1}[/tex]

x=8

So apparently she currently has far too many trees per acre. To get the maximum yield, she needs to reduce the number of trees per acre by 8.

So the number of trees per acre for maximum yield is 25-8 = 17.

B) 20 to 29: one of 21 pounds, one of 27, one of 23 and one of 25, so here we have 4 dogs.

C) 30 to 39. here we have the left 3 dogs.

then the table is:

[tex]\left[\begin{array}{ccc}range&dogs\\10to19&3\\20to29&4\\30to39&3\end{array}\right][/tex]

For the afternoon, the weights of the dogs are:
