F(x) = x - 6
g(x) = 3x2 + 5x – 5
Find: g(f(x))

Answers

Answer:

Step-by-step explanation:

g(x - 6)= 3(x - 6)^2 + 5(x - 6) - 5

= 3(x^2 - 12x + 36) + 5x - 30 - 5

= 3x^2 - 36x + 108 + 5x - 35

= 3x^2 - 31x + 73

If a square plate has side lengths of 5 inches, what is the length of the diagonal to the nearest tenth of an inch?

Answers

It is given that the plate is a square.

Therefore, let us represent the side of the square by the variable, "a".

Therefore, it is given to us that: $a=5$ inches.

Now, we have to find the diagonal of the square. We know that the diagonal, $d$ of a square is given by the formula:

$d=a√(2)$

Applying the above formula to our case we get the diagonal to be as:

$d=5√(2)\approx7.07$ inches.

Therefore, the length of the diagonal to the nearest tenth of an inch is:

$d=7.1$ inches.

Use the Pythagoras theorem:-

diagonal^2 = 5^2+5^2 = 50
diagonal = sqrt 50 = 7.1 inches to nearest tenth
