Murljashka [212]

Answer:

a. 8.4 ft³

b. 4.44 ft × 2.44 ft × 0.78 ft

Step-by-step explanation:

a. <em>Maximum volume </em>

We are creating a box with dimensions

l    = 6 – 2x

w = 4 – 2x

h = x

V = lwh  = x(6 – 2x)(4 – 2x)

We must determine the value of x that makes V a maximum.

One way is to plot the function V = x(6 – 2x)(4 – 2x).

The maximum appears to be at about (0.78, 8.4).

Thus, the maximum volume is 8.4 ft³.

b.<em> Dimensions </em>

 l = 6 – 2 × 0.78 = 6 – 1.56 = 4.44 ft

w = 4 – 2 × 0.78 = 4 – 1.56 = 2.44 ft

                                         h = 0.78 ft

The box with maximum volume has dimensions 4.44 ft × 2.44 ft × 0.78 ft.

Sammy is trying to determine how many triangles she can create out of a square grid that has a side of 14 inches. Use the image
saw5 [17]
Hello!

You first have to find the area of the square grid

To find this you multiply the sides

14 * 14 = 196

Next you have to find the area of the triangle

To find the area of a triangle you use the equation

\frac{hb}{2}

h is height
b is base

Put in the values you know
\frac{7 * 14}{2}

Multiply

\frac{98}{2} = 49

The area of the triangle is 49 inches squared

You divide the area of the triangle by the area of the square

196 / 49 = 4

The answer is 4 triangles

Hope this helps!

Consider the function.
Mariana [72]

Answer: (2 1/2, 0) (the last option)

Step-by-step explanation:

I guess the function is:

f(x) = (2  1/2) - (3  1/2)*x

now, the rule for f-1(x) that we know is:

f-1( f(x) ) = x.

So if we want to find the x-intercept of f-1(x), we must evaluate it in f(0)

f-1(f(0)) = 0.

And we have that f(0) = (2  1/2) - (3  1/3)*x = 2  1/2

This means that the x-intercept of f-1(x) will be when x= 2  1/2, so the intercept is:

(2 1/2, 0)
