Find two positive real numbers with the given sum whose product is a maximum. The sum of the first and twice the second is 24
Elenna [48]
Y+2x=24
product is max
xy=max

we have
y+2x=24
minus 2x both sides
y=24-2x
sub that for y in xy=max
(24-2x)(x)=max
-2x^2+24x=max
we have a parabola opening down
the coordinates of the vertex is our answer

the x value of the vertex is -b/2a where
ax^2+bx+c=y

-24/2(-2)=-24/-4=6
xvalue=6

we can just sub
y=24-2x
y=24-2(6)
y=24-12
y=12
the numbers are 6 and 12
the product is 72



the numbers are 6 and 12

The table below shows some values that satisfy a linear function.
Makovka662 [10]

Answer:

1.5

Step-by-step explanation:

Given the pair of points on the table.

Now the formula for slope, m=\dfrac{y_2-y_1}{x_2-x_1}

To calculate the slope we only require two pair of points.

Let us take: (x_1, y_1)=(-5,0)$ and (x_2, y_2)=(-3,3)

m=\dfrac{3-0}{-3-(-5)}\\=\dfrac{3}{-3+5}\\=\dfrac{3}{2}\\m=1.5

The slope of the linear function represented by the values in the table is 1.5.

Note: You can use any two set of values. The result will be the same.

Find the height "h" so that its area is equal to 400 square cm.
jenyasd209 [6]

Answer:

h = 20 cm

Step-by-step explanation:

The area of a trapezoid is given by

A = 1/2 (b1+b2) *h

where b1 and b2 are the two bases

We are given a =400 and b1 =27 and b2 =13

400 = 1/2 (27+13) *h

400 = 1/2 (40) *h

400 = 20h

Divide each side by 20

400/20 = 20h/20

20 =h
