The answer is A. Use the given functions to set up and simplify f(-2).
Answer:
80% 0.8
Step-by-step explanation:
To find the percentage out of a fraction you would divide 4÷5 to get 0.8, the decimal answer, then to turn that to a percent you would move the point two places to the right to get 80%.

- [Right Triangles Only] Pythagorean Theorem: a² + b² = c²
Step-by-step explanation:
<u>Step 1: Define</u>
We are given a right triangle. We can use PT to find the missing side.
<u>Step 2: Identify Variables</u>
Leg <em>a</em> = 5
Leg <em>b</em> = <em>x</em>
Hypotenuse <em>c</em> = 12
<u>Step 3: Solve for </u><em><u>x</u></em>
- Substitute: 5² + x² = 12²
- Isolate <em>x</em> term: x² = 12² - 5²
- Exponents: x² = 144 - 25
- Subtract: x² = 119
- Isolate <em>x</em>: x = √119
Answer:
Step-by-step explanation:
ratio of pencil by ball pen
pencil=25 per score
ball pen =12 per 10
10 pens 12rs
12÷10=6/5
20 pencils 25rs
25÷20=5/4
ratio=6/5÷5/4
6/5×4/5
24/25
Answer:
y = (x-5)(x+2)
Step-by-step explanation:
the zeros are the solution to 'x' of each factor:
x-5=0; x=5
x+2=0; x = -2
