Given that the f(y) = y - 1 and g(y) = y^3 - 2y - 1, find (gof) (y)I and hence, (gof) (-6).

Answers

Answer 1

Answer:

$(g \circ f)(y)=(y-1)^3-2(y-1)-1\n(g \circ f)(y)=y^3 - 3 y^2 + 3 y - 1-2y+2-1\n(g \circ f)(y)=y^3 - 3 y^2 +y\n\n(g \circ f)(-6)=(-6)^3-3\cdot(-6)^2+(-6)\n(g \circ f)(-6)=-216-108-6\n(g \circ f)(-6)=-330$

A deli charges the same price, $4.60, for all of its different sandwiches. If a company ordered n sandwiches for a luncheon, which equation could be used to find the total price, P, that the deli charged for the sandwiches?

Answers

4.6 * n = p
4.6 = price for a sandwich
n = how much sandwich that company ordered
p = the total price

What is 72 % of 350 friends

Answers

'is' in mathematics means equal
'of' in mathematics means multiplication

72% can also be written as 72/100

We are solving for the variable 'x'

$x = (72)/(100) * 350\n\nx = 72 * 3.5\n\n\boxed{\bf{x = 252}}$

350 friends* (72/100)= 252 friends.

Final answer: 252 friends~

What is the surface area of the figure? 7ft 7ft 12ft 12ft 5ft

Answers

This shape seems to be like a rectangular prism because of its dimensions
7 ft × 2 (widths)
12 ft × 2 (lengths)
5 ft (height of prism)

Formula of the surface area of a prism is:
2 × Area of base + Perimeter × Height of prism
Area of rectangle (length × width)
Perimeter of rectangle (2×length + 2×width)
2 × (12 × 7) +(2×12+2×7) × 5
168 + 190
358 ft²

Step-by-step explanation:

A function is shown f(x)=2/3x+3 what is the value of f(12)

Answers

The value of f (12) will be;

⇒ f (12) = 11

What is substitution method?

To find the value of any one of the variables from one equation in terms of the other variable is called the substitution method.

Given that;

The function is,

⇒ f (x) = 2/3x + 3

Now,

Since, The function is,

⇒ f (x) = 2/3x + 3

Substitute x = 12 in above equation, we get;

⇒ f (x) = 2/3x + 3

⇒ f (12) = 2/3 × 12 + 3

⇒ f (12) = 2 × 4 + 3

⇒ f (12) = 11

Thus, The value of f (12) will be;

⇒ f (12) = 11
