If f(x) = x^2- 6 and g(x) = 2x – 1, determine the value of (gºf)(-3).

1 answer:

5 0

I’m not too sure if I did it correct, but the answer I got was -6x^2+36. I just assumed you’d solve it as usual and then multiply (-3) after distributing-2 to x^2-6. Hope this helps.

Silvia buys 12 steaks that are each 34 of a pound. She spends a total of $90 on steaks. Complete each sentence. Silvia buys a to

scZoUnD [109]

I think in the first sentence, that should have been 3/4 instead of 34. Total amount of steak bought (lb)
total amount = (3/4 lb/steak)(12 steak) = 9 lb
To find the total amount that Silvia spends for each pound of steak, we divide $90 by 9 and that will give us an answer of $10.

What is the approximate perimeter of a semicircle with a radius of 9mm?

Cerrena [4.2K]

Act like it's a whole circle and find the perimeter, then divide by 2.

P = 2 * pi * r

P = 2 * 3.14 * 9

P = 56.52

Now divide by 2:

P = 28.26
