600 divided by 20=30
30x2=60 which is the answer

equation= 600=2x area divied by height

Answer:

Total length of iron needed to make the square frame and two diagonals = 43.44 in (Approx)

Step-by-step explanation:

Given:

Length of diagonal = 9 in

Find:

Total length of iron needed to make the square frame and two diagonals.

Computation:

Area of square = 1/2(diagonal)²

Area of square = 1/2(9)²

Area of square = 40.5 in²

Area of square = Side × Side

40.5 in² = Side × Side

Side = 6.36 (approx)

Total length of iron needed to make the square frame and two diagonals = Permeter of square + (2 × diagonal)

⇒ (4 × 6.36) + (2 × 9)

⇒ (25.44) + (18)

⇒ 43.44 in

Total length of iron needed to make the square frame and two diagonals = 43.44 in (Approx)

What is the domain of the function?<br> x + 3<br> f(x) =<br> VX + 3

ahrayia [7]

Your question is a little ambiguous, but I am assuming that you meant to say the function $f(x) = x+3$

Thus, I am solving your question based on assuming the function such as

$f(x)=x+3$

But, it would still clear your concept, no matter what the function is.

Answer:

we conclude that

$\mathrm{Domain\:of\:}\:x+3\::\quad \begin{bmatrix}\mathrm{Solution:}\:&\:-\infty \:$

The graph is also attached.

Step-by-step explanation:

Given the function

$f(x)=x+3$

We know that the domain of a function is the set of input or argument values for which the function is real and defined.

As the function has no undefined points nor domain constraints.

Thus, the domain is

$-\infty \:$

Therefore, we conclude that

$\mathrm{Domain\:of\:}\:x+3\::\quad \begin{bmatrix}\mathrm{Solution:}\:&\:-\infty \:$

The graph is also attached.

What is the surface area using integrals of these two lines. Y=10-x^2 and Y=x^2+2 from the bounds x=2 and x=-2.

Lelu [443]

Check the picture below.

$\bf \displaystyle\int\limits_{-2}^{2}~[\stackrel{\textit{above function}}{(10-x^2)}~~-~~\stackrel{\textit{below function}}{(x^2+2)}]dx\implies \int\limits_{-2}^{2}~(10-x^2-x^2-2)dx \\\\\\ \displaystyle\int\limits_{-2}^{2}~(8-2x^2)dx\implies \left. 8x\cfrac{}{} \right]_{-2}^{2}-\left. \cfrac{2x^3}{3} \right]_{-2}^{2} \\\\\\ ([16]-[-16])~~-~~\left( \left[ \cfrac{16}{3} \right]-\left[ -\cfrac{16}{3} \right]\right)\implies (32)~~-~~\left( \cfrac{32}{3} \right) \\\\\\ \cfrac{64}{3}\implies 21\frac{1}{3}$

PLEASE help me with this problem and explain the steps you used.

Bad White [126]

I hope this helps you

14= 2/3 (9y-15) divided 2 each sides

7= 9y-15/3

7.3= 9y-15

21+15= 9y

36= 9y

y= 4
