You are given f(0) = 1 and g(0) = -2 and g(1) = 3. What is <br> g ∘ f ( 0 ) <br> equal to?
Sergeu [11.5K]

Answer:

  • <u><em>g∘f (0) = 1</em></u>

Explanation:

The <em>composition</em> of the <em>functions</em> f and g represented by g ∘ f ( 0 ) means that g is applied to f(0), i.e f(0) is the input to the function g.

Since f(0) = 1, you are going fo find g(1):

         \( g\circ f(x)=g(f(x)) \)\\\\\( g\circ f(0)=g(f(0)) \)\\\\\( g\circ f(0)=g(1) \)=3

The recommended dose for a brand nicotine patch is one 21-mg dose per day for 6 weeks, followed by 14 mg per day for 2 weeks, an
coldgirl [10]

Answer:

1.176 grams

Step-by-step explanation:

Given:

Recommended dose

21 mg per day for 6 weeks

Now,

1 week = 7 days

Thus,

number of days in 6 weeks = 6 × 7 = 42 days

Therefore, the total dose = dose per days × number of days

= 21 × 42 = 882 mg

further,

14 mg per day for 2 weeks

Now,

1 week = 7 days

Thus,

number of days in 2 weeks = 2 × 7 = 14 days

Therefore, the total dose = dose per days × number of days

= 14 × 14 = 196 mg

further,

7 mg per day for 2 weeks

Now,

1 week = 7 days

Thus,

number of days in 6 weeks = 2 × 7 = 14 days

Therefore, the total dose = dose per days × number of days

= 7 × 14 = 98 mg

Hence, the total dose = 882 + 196 + 98 = 1176 mg

also,

1 g = 1000 mg

thus,

1176 mg = 1.176 grams

total quantity received during this course is 1.176 grams
