Answer:
a. 38
b. 95
c. 57
Step-by-step explanation:
In this context, you can consider "of" to mean "times." It can also be helpful to think of % as meaning /100.
a. p = 20% × 190
p = 20/100 × 190 = 38 . . . . you have 38 pennies
__
b. 190 = 200% × r
190 = 200/100 × r . . . . replace % with /100
190 = 2 × r . . . . . . . . . simplify the fraction
190/2 = r = 95 . . . . you have 95 rare coins
__
c. n = 60% × r
n = 60/100 × 95 = 57 . . . . you have 57 nickels
900-573=327 To reach their goal the least amount of books they need to read is 327
<span>So you have composed two functions,
</span><span>h(x)=sin(x) and g(x)=arctan(x)</span>
<span>→f=h∘g</span><span>
meaning
</span><span>f(x)=h(g(x))</span>
<span>g:R→<span>[<span>−1;1</span>]</span></span>
<span>h:R→[−<span>π2</span>;<span>π2</span>]</span><span>
And since
</span><span>[−1;1]∈R→f is defined ∀x∈R</span><span>
And since arctan(x) is strictly increasing and continuous in [-1;1] ,
</span><span>h(g(]−∞;∞[))=h([−1;1])=[arctan(−1);arctan(1)]</span><span>
Meaning
</span><span>f:R→[arctan(−1);arctan(1)]=[−<span>π4</span>;<span>π4</span>]</span><span>
so there's your domain</span>
