Step-by-step explanation:
I just answered this. so here again :
let's start with
1 inch = 2.54 cm
1 ft = 12 in = 2.54×12 = 30.48 cm
1 yd = 3 ft = 3×30.48 = 91.44 cm
1 meter = 100 cm
this should be enough to answer the problems :
a.)
25 ft = 25 × 30.48 cm = 762 cm = 762/100 m = 7.62 m
b.)
67 m = 6700 cm = 6700/2.54 in = 2,637.795276... in
c.)
8.5 yd = 8.5 × 91.44 cm = 777.24 cm
d.)
90 cm = 90/2.54 in = 35.43307087... in
Answer:
The value of f(-2) is equal to 14.
Step-by-step explanation:
Let's define what we are given:
Recall from function notation that f(-2) is <em>equal to</em> x = -2 for f(x). That means we can <em>substitute in </em>x = -2 <em>into</em> f(x):
- f(-2) = 3(-2)² - (-2)
From here, we can evaluate the function expression using BPEMDAS (Brackets, Parenthesis, Exponents, Multiplication, Division, Addition, and Subtraction):
- f(-2) = 3(-2)² - (-2)
- f(-2) = 3(4) - (-2)
- f(-2) = 3(4) + 2
- f(-2) = 12 + 2
- f(-2) = 14
∴ f(-2) = 14.
Hope this helps!
