Answer:

It is not correct.

Step-by-step explanation:

From the picture we can see that the length of the sides of square C is 50 ft.

A right triangle is formed, where the diagonal of square C is the hypotenuse (c) and two sides of the square C are the other sides of the right triangle (a and b). From Pythagorean theorem:

c² = a² + b²

c² = 50² + 50²

c = √5000

c = 70.71 m

Write a recursive formula for the following arithmetic sequence.<br> 8, 5, 2, −1,
Kamila [148]

Answer:

a_{n} = a_{n-1} - 3

Step-by-step explanation:

A recursive formula allows a term in the sequence to be found from the previous term by adding the common difference to it.

Here d = 5 - 8 = - 3, thus

a_{n} = a_{n-1} - 3 with a₁ = 8 ← recursive formula

If (x)=<br> X-2<br> and d(x) = x + 3, what is the domain of (cd)(x)?
Nata [24]

Answer:

Option (2)

Step-by-step explanation:

Given functions are,

c(x) = \frac{5}{x-2}

d(x) = x + 3

Equation of the composite function will be,

(cd)(x) = c(x) × d(x)

          = \frac{5}{(x-2)}\times (x+3)

          = \frac{5(x+3)}{(x-2)}

This function is defined only when denominator is not equal to zero.

(x - 2) ≠ 2

Therefore, for real numbers except x = 2 will be the domain of the composite function.

Option (2) will be the answer.

Please please please help me
Yuri [45]

Answer:

Step-by-step explanation:

Since all the answers are 100s I assume the sizes are 10, 10 and 20.

This would mean there are 2 sides of 10x10 and 4 of 10x20

The total area would be 2*100+4*200=1000. Since that's obviously not one of the answers. We can assume it's probably 15 since it should give us a full 100 number. We know the other two are probably 10 due to their sizes and them obviously being two digits. This would mean it would be 2*100+4*150=800
