I need help with this did I get this right

You’re very close! This is a triangular prism which means that the triangle portion has a unique formula. In order to find area of the triangle you do (base x height) and then divided by 2. In this case, base=6 and height=5 so 6x5=30 and 30 divided by 2 is 15. Then multiply by the length which is 10. The final answer is 150cm cubed.

Find a formula for the described function. an open rectangular box with volume 9 m3 has a square base. express the surface area

Maru [420]

Let

x--------> the length side of the square base

h--------> the height of the box

we know that

<u>the volume of the box is equal to</u>

$V=x^{2} *h\\ V=9\ m^{3}$

so

$x^{2} *h=9\\\\h=\frac{9}{x^{2} }$

<u>the surface area of the box is equal to</u>

$SA=area\ of\ the\ base+perimeter\ of\ base*height$ (remember that the box is open)

area of the base= $(x^{2})\ m^{2}$

Perimeter of the base= $(4*x)\ m$

height=(h) m

$h=\frac{9}{x^{2}}$

substitute

$SA=x^{2} +4*x*h\\ \\ \\ SA=x^{2} +4*x*\frac{9}{x^{2} } \\ \\ SA=x^{2} +\frac{36}{x}$

we know that

the value of x can not be negative and the denominator can not be zero

therefore

<u>the answer is</u>

the domain of SA is x> 0

the domain is the interval-------------> (0,∞)

Answer:

-5 and initial value is -1

Step-by-step explanation:

Slope= y2-y1/x-x1

-11-(-1)/2-0

-10/2

-5

Initial value is y-intercept where x is 0 (0,y)

so

(0,-1) is starting point
