Correct me if i'm wrong, but i think it's b, since you add the exponents and keep the 4 the same.
47 (numeral)
forty seven (in words)
40 + 7 (expanded form)
4 tens and 7 ones (tens and ones)

Question says to find the square root of 3.24.
To find square root of decimal numbers, we can start by converting them into fraction so that decimal gets removed then find square root of numerator and denominator separately.
there are two digits after decimal in 3.24 so we can rewrite 3.24 as 324/100
Now let's find square root of the resulting fraction

Hence final answer is 1.8.
Answer: 1. A
2.C
3.D
4.C
5.D
Step-by-step explanation:
Dy/dx=-2x+15
d2y/dx2=-2
Since the acceleration is a constant negative it has an absolute maximum value for y(x), thus it opens downward, as x decreases without bound as x approaches ±∞
