Solution:

we are given that

The fairy tale spectacular is coming to town. Admission to the fair costs $32.50 and each ride costs $.80.

You have $50 to spend at the fairy tale spectacular including admission.

Suppose you took x ride, then we can write.

So the inequality can be written as below:

$32.50+0.80x\leq 50$

PartB:

Now lets solve the inequality

$32.50+0.80x\leq 50\\\\ 0.80x\leq 50-32.50\\\\0.80x\leq 17.50\\\\x\leq 21.875$

Hence you can take a maximum of 21 rides.

Question 3 Unsaved

bazaltina [42]

Answer:

Step-by-step explanation:

DE given is

y''+8y'+15y=0, y(0)=0, y'(0)=1

Take Laplace on the DE

We get

$s^2 Y(s) -sY(0) -y'(0)+8(sY(s)-y(0))+15Y(s) =0\\s^2 Y(s) -s(0) -1+8(sY(s)-0)+15Y(s) =0\\Y(s)(s^2+8s+15)-1=0\\Y(s) = \frac{1}{s^2+8s+15}$

Simplify to get

Y(s) = $\frac{1}{2}[ {\frac{1}{s+3} -\frac{1}{s+5} }]$

Take inverse

$y(t) = \frac{e^{-3t} -e^{-5t}}{2}$
