Can i please get some help with this?

Mathematics

The answer is 45 degrees. Each angle of a square is known to be 90 degrees. According to the picture, segment AC bisects (splits in half) the angle. Thus, you would do 90/2 to get 45 or the measure of angle BAC. Hope this helped :))

A standard deck of cards contains 52 cards. one card is selected from the deck. ?(a) compute the probability of randomly selecti
Rama09 [41]
Let
P(h)= probability of selecting heart = 13/52= 1/4
similarly
P(s)= probability of selecting spade =1/4
P(c)= probability of selecting club =1/4
P(d)= probability of selecting diamond =1/4

a)

P(h or s)= P(h)+P(s)= 1/4+1/4=2/4=1/2=0.5

b)

P(h or s or c)=P(h)+P(s)+P(c)=1/4+1/4+1/4=3/4=0.75

c) 

P(2 or a diamond)=n(2heart, 2spade,2club,13 diamonds)/total number of cards

=(1+1+1+13)/52=16/52=4/13=0.3

or we could solve it as follows:

P(2 or a diamond)=P(2)+P(diamond)-P(2diamond)=4/52  +  13/52  + 1/52  = (4+13-1)/52=16/52=0.3

What are the coordinates of A?
Nitella [24]

Answer:

The coordinates of A could be anything in the form of (x, y, z) if you have a third axis. First you count where A is on the x-axis then the y-axis and if you have a 3-dimensional graph then the z-axis.

A particle moves along the x-axis so that at time t its position is given by s(t) = (t + 1)(t - 3)3, t > 0. /p>For what va
Zepler [3.9K]

Given the position function, the velocity function is obtained by taking the derivative:

s(t)=(t+1)(t-3)^3\implies v(t)=(t-3)^3+3(t+1)(t-3)^2

The velocity is increasing its own derivative is positive, so we also have to find the acceleration by taking another derivative:

a(t)=4(t-3)^3+3(t-3)^2+6(t+1)(t-3)

To find when a(t)>0, we first need to know where a(t)=0:

4(t-3)^3+3(t-3)^2+6(t+1)(t-3)=(t-3)\bigg(4(t-3)^2+3(t-3)+6(t+1)\bigg)=(t-3)(4t^2-15t+33)=0

The quadratic factor is always positive (its discriminant is negative), which leaves one solution at t=3. To either side of t=3, we have, for instance,

a(2)=-12

a(4)=36>0

which indicates that v(t) is increasing for t>3, making the answer A.
