Answer:

f(x) = -4x-1

f(7) = -(4)(7)-1

f(7) = -29

g(x) = 4x^2 - x

g(-4) = 4(-4)^2 - (-4)

g(-4) = 4(16) + 4

g(-4) = 64 + 4

g(-4) = 68

Let me know if this helps!

Janet is drawing the path formed by the parametric equations x=2+3 sin t and y=1-1/2cos t. Which curve did she draw??

irakobra [83]

Sin²t +cos²t =1

 x=2+3 sin t
sin t=(x-2)/3

y=1-1/2cos t
y-1= - (cos t)/2
cos t =-(y-1)/(1/2)

(x-2)²/3² + (y-1)²/(1/2)² = 1

Suppose n(X) = 28 and n(Y) = 19.

Flauer [41]

$n(X\cup Y)=n(X)+n(Y)-n(X\cap Y)$

If $X$ and $Y$ share no common elements, then $n(X\cap Y)=0$ , which means $n(X\cup Y)=n(X)+n(Y)=47$

On the other hand, if the smaller set is entirely contained within the larger set, i.e. $Y\subseteq X$ , then $X\cap Y=Y$ , and so $n(X\cup Y)=n(X)+n(Y)-n(Y)=n(X)=28$ .
