Volume = Cross-sectional area * length
C-S area = 1/2 * b * h
1/2(4)(15) = 30
length = 18
Volume = 30 * 18
= 540 mm^3

S' area = 2(C-S area) + 8(18) + 15(18) + 17 (18)
= 2(30) + 8(18) + 15(18) + 17(18)
= 60 + 144 + 270 + 306
= 780 mm^2

Calculate the perimeter and area of the following square if a= 19
Licemer1 [7]

Formula for perimeter of a square: P = 4a

Formula for area of a square: A = a²

a is given as:

19

Plug this value for a into the above formulas to solve for perimeter and area.

P = 4a

P = 4(19)

P = 76

-----------------------------------------------------------------------------------------------------------------

A = a²

A = 19²

A = 361

Answer:

P = 76 units; A = 361 units².

Miller's Steakhouse offers 8 side dishes, 5 types of steak, and 4 toppings. How many different smothered steak dinners can be ma
horrorfan [7]

Answer:

1120

Step-by-step explanation:

To find the possible number of steak dinners, you would multiply the number of choices for each part of the dinner. You would used combinations instead of permutations since the order of the toppings chosen or side dishes chosen do not matter. There are 5 choose 1 choices for types of steak, which is just 5. There are 8 choose 3 choices for side dishes, which is 56. There are 4 choose 3 choices for toppings, which is 4. 5*56*4 is 1120, so there are 1120 possible steak dinners.

Use a graphing calculator to graph f(x) = x+cos(kx). Use calculus to determine which values of k lead to a function with no loca
nataly862011 [7]

Answer:

Below, you can see the graph of the function:

f(x) = x + cos(k*x)

for different values of k, as follows:

red: k = 1

green: k = 2

orange: k = 0.

Now let's find the values of k such that our function does not have local maxima nor local minima.

First, remember that for a given function f(x), the local maxima or minima points are related to the zeros of the first derivate of f(x).

This means that if:

f'(x0) = 0.

Then x0 is a maxima, minima or an inflection point.

Then if a function is such that the f'(x) ≠ 0 , ∀x, then this function will not have local maxima nor minima.

Now we have:

f(x) = x + cos(k*x)

then:

f'(x) = 1  - k*sin(k*x)

This function will be zero when:

1 = k*sin(k*x)

1/k = sin(k*x)

now, remember that -1 ≤ sin(θ) ≤ 1

then if 1/k is smaller than -1, or larger than 1, we will not have zeros.

And this will happen if -1 < k < 1.
