Answer:

$A=40cm^{3}$

Step-by-step explanation:

Formula to find the surface area of a rectangular prism:

$A=2(wl+hl+hw)$

$(w=weight, l=length, h=height)$

$A=2((2)(4)+(2)(4)+(2)(2))$

$A=2((2)(4))+2((2)(4))+2((2)(2))$

$A=16+16+8$

$A=40cm^{3}$

Answer:

36 cm^2

Step-by-step explanation:

S.A. = 2 (lw + wh + lh)

S.A. = 2 ((4)(2) + (2)(2) + (4)(2))

S.A. = 2 (8 + 4 + 6)

S.A. = 2 (18)

S.A. = 36

an unopened can of iced tea contains 350 cubic centimeters of liquid. if the van is 5 inches long and has a .8 inch diameter, wh

MariettaO [177]

the can is 5 inches tall, so its height is 5 inches, so 3 inches off 5 inches that'd be 3/5.

the can has a diameter of 0.8 inches, meaning it has a radius of half that, or 0.4 inches.

if say the volume of iced-tea is V, how much is 3/5 of V? well, is just their product.

$\bf \textit{volume of a cylinder}\\\\ V=\pi r^2 h~~ \begin{cases} r=radius\\ h=height\\[-0.5em] \hrulefill\\ r=0.4\\ h=5 \end{cases}\implies V=\pi (0.4)^2(5)\implies V=0.8\pi \\\\\\ \stackrel{\textit{and 3/5 of that will be}}{\cfrac{3}{5}\cdot 0.8\pi }\implies V\approx \stackrel{in^3}{1.51}$

What is the base of the exponetim the function f(x)=3(3/8)^2 when the function f(x)=3

galina1969 [7]

Answer:

Depending on what the equation is (see below for options) answers are:

$\frac{log1}{log\frac{3}{8}} = x$ or -1,1=x

Step-by-step explanation:

Two possibilities are present:

The base of an exponential function is the number raised to an exponent of x. $f(x) = 3(3/8)^x$ . The base here is 3/8. To find when f(x) = 3, then substitute and solve. $3=3(\frac{3}{8})^x\\1=(\frac{3}{8})^x\\log 1 = log \frac{3}{8}^x\\\frac{log1}{log\frac{3}{8}} = x$

If this is a quadratic function then it has a base of x. $f(x) = 3(x)^2$ . To find when f(x) = 3 then substitute and solve. $3=3(x^2)\\1=x^2\\1,-1=x$
