The answer is 290 inches squared.
The surface area is = the sum of all sides. There are 4 sides that equal 60 (60 x 4 = 240), and 2 sides that equal 25 (25 x 2 = 50), the surface area is equal to 240 + 50 which equals 290.

Answer:

290 in^2

Step-by-step explanation:

So what you do is you use the formula of the surface area of a rectangle which is SA=2lw+2lh+2hw.

The length=5. The width=5. The height=12.

You put those numbers into the formula.

2(5)(5)+2(5)(12)+2(12)(5)=290 in^2.

Given limit f(x) = 4 as x approaches 0. What is limit 1/4[f(x)]^4 as x approaches 0?

stepladder [879]

Answer:

$\displaystyle 64$

General Formulas and Concepts:

Calculus

Limits

Limit Rule [Variable Direct Substitution]: $\displaystyle \lim_{x \to c} x = c$

Limit Rule [Variable Direct Substitution Exponential]: $\displaystyle \lim_{x \to c} x^n = c^n$

Limit Property [Multiplied Constant]: $\displaystyle \lim_{x \to c} bf(x) = b \lim_{x \to c} f(x)$

Step-by-step explanation:

Step 1: Define

Identify

$\displaystyle \lim_{x \to 0} f(x) = 4$

Step 2: Solve

Rewrite [Limit Property - Multiplied Constant]: $\displaystyle \lim_{x \to 0} \frac{1}{4}[f(x)]^4 = \frac{1}{4} \lim_{x \to 0} [f(x)]^4$
Evaluate limit [Limit Rule - Variable Direct Substitution Exponential]: $\displaystyle \lim_{x \to 0} \frac{1}{4}[f(x)]^4 = \frac{1}{4}(4^4)$
Simplify: $\displaystyle \lim_{x \to 0} \frac{1}{4}[f(x)]^4 = 64$

Answer:

process: substitute the given point values into the 2-point form of the equation for a line

Step-by-step explanation:

There are more than a half-dozen different forms of the equation for a line. They are useful for different purposes. One of them is the "two-point form".

Using x as the independent variable, and y as the dependent variable, the equation can be written as ...

y -y1 = (y2 -y1)/(x2 -x1)/(x -x1)

where (x1, y1) and (x2, y2) are the two points.

Here, your two points are ...

(t, s) = (10, 337) and (30, 349)

Using s in place of y, and t in place of x, these two points go into the formula like this:

s -337 = (349 -337)/(30 -10)(t -10)

Simplifying the fraction, this is ...

s -337 = (12/20)(t -10)

And writing it as a decimal, we get ...

s -337 = 0.6(t -10)

_____

Additional comments

Adding y1 to both sides of the above form gives you ...

y = (y2 -y1)/(x2 -x1)/(x -x1) +y1

This is the form I usually prefer to use, because it can lead directly to slope-intercept form. For this problem, the form shown above gets you to the answer you're looking for.

This "two-point form" is an expansion of the "point-slope form", which is ...

y - k = m(x -h) . . . . . . . line with slope m through point (h, k)

where the equation for slope is ...

m = (y2 -y1)/(x2 -x1)

and (x1, y1) is used instead of (h, k).
