We just went over this in class and it’s actually quite easy once you get your head around it!

Im not quite sure what the second one it asking but here’s an idea :)

you need them all to be on the same side so you can do
x^2 - 4x - 12 = 0
(x-6)(x+2) = 0
x = 6 or 2
(each bracket must equal 0)

A particular baseball player has a batting average (number of hits/number of times at bat) of 0.364. What is the probability tha

MAXImum [283]

The correct answer is option (c) P(not a hit) = 0.636

The batting average of the baseball player = $\frac{number of hits}{number of times at bat}$ = 0.364

Now, the probability of occurrence of any event is say, P, the probability of not occurrence of the event is given as = 1 - P

Therefore, the probability that he will not get a hit at his next at bat = 1- 0.364 = 0.636

The curve given by x=sin(t),y=sin(t+sin(t)) has two tangent lines at the point (x,y)=(0,0). List both of them in order of increa

SOVA2 [1]

Answer:

y = 0

y =2x

Step-by-step explanation:

Given parametric equations:

x (t) = sin (t)

y (t) = sin (t + sin (t))

The slope of the curve at any given point is given by dy / dx we will use chain rule to find dy / dx

(dy / dx) * (dx / dt) = (dy / dt)

(dy / dx) = (dy / dt) / (dx / dt)

Evaluate dx / dt and dy / dt

dx / dt = cos (t)

dy / dt = cos (t + sin (t)) * (1+cos (t))

Hence,

dy / dx = (1+cos(t))*cos(t + sin (t))) / cos (t)

@Given point (x,y) = 0 we evaluate t

0 = sin (t)

t = 0 , pi

Input two values of t and compute dy / dx

@ t = 0

dy / dx = (1 + cos (0))*cos (0 + sin (0))) / cos (0)

dy / dx = (1+1)*(1) / (1) = 2 @ t = 0

@t = pi

dy / dx = ( 1 + cos (pi))* cos (pi + sin (pi)) / cos (pi)

dy / dx = (1-1) * (-1) / (-1) = 0 @ t = pi

The corresponding gradients are 0 and 2 in increasing order and their respective equations are:

y = 2x

y = 0
