Answer:
1. The input is f
2. The input is g
3. The input is h
Step-by-step explanation:
The value inside the bracket of the function is the input given to the function.
1. g(f) = 2f
The input is f
2. h(g) = -4+g
The input is g
3. f(h) = h - 7
The input is h

Find the area of the base B
substitute
Answer:
600
Step-by-step explanation:
divide 360 by 6 and you get how many pounds that can make in one hour.
which is 60 so then you multiply 60 by 10 and get 600

12 feet of wire.
Answer:
option b)
tan²θ + 1 = sec²θ
Step-by-step explanation:
The Pythagorean trigonometric identity is a trigonometric identity expressing the Pythagorean theorem in terms of trigonometric functions.
hypotenuse² = height² + base²
Given in the questions are some pythagorus identities which except of b) are all incorrect as explained below.
<h3>1)</h3>
sin²θ + 1 = cos²θ incorrect
<h3>sin²θ + cos²θ = 1 correct</h3><h3 /><h3>2)</h3>
by dividing first identity by cos²θ
sin²θ/cos²θ + cos²θ/cos²θ = 1/cos²θ
<h3>tan²θ + 1 = sec²θ correct</h3><h3 /><h3>3)</h3>
1 - cot²θ = cosec²θ incorrect
by dividing first identity by sin²θ
sin²θ/sin²θ + cos²θ/sin²θ = 1/sin²θ
<h3>1 + cot²θ = cosec²θ correct</h3><h3 /><h3>4)</h3>
1 - cos²θ = tan²θ
not such pythagorus identity exists
