We know that
cos 60°=1/2
cos 30°=(√3)/2
so
cos 60°=x/14---------> x=14*cos 60°----> x=14*(1/2)-----X=7 units
and
cos 30°=y/14---------> y=14*cos 30°----> x=14*(√3)/2----> y=7√3 units

the answers are
x=7 units
y=7√3 units

When playing the lottery game Cash4Life, you must choose a cash ball number from 1 through 4. What is the probability that the r
Butoxors [25]

Answer:

P(At\ least\ 2) = 0.75

Step-by-step explanation:

Given

Balls = 1 to 4

Required

Determine the probability of selecting ball numbered at least 2

Here, we'll assume that all numbers have the same probability.

The probability of each ball will be:

Probability = \frac{1}{4}

So:

P(At\ least\ 2) = P(2) + P(3) + P(4)

Recall that

Probability = \frac{1}{4} --- for each ball

So, the equation becomes

P(At\ least\ 2) = \frac{1}{4} + \frac{1}{4} + \frac{1}{4}

P(At\ least\ 2) = \frac{3}{4}

P(At\ least\ 2) = 0.75

Y = mx+b

m= 4 

y= 4x+b

solve for b using (6,-1)

-1 = 4 (-1)+b
b=3

therefore equation is y=4x+3

same as (y+1)=4(x-6)

Point M is the midpoint of AB¯¯¯¯¯¯¯¯. Find the length of AB¯¯¯¯¯¯¯¯.
alina1380 [7]

Answer:

AB = 142

Step-by-step explanation:

If M is the midpoint, then AM = MB

6x+5 = 7x -6

Subtract 6x from each side

6x-6x+5 = 7x-6x -6

5 = x-6

Add 6 to each side

5+6 = x-6+6

11=x

We want to find AB

AB = 6x+5+7x-6

AB = 13x -1

     = 13(11) -1

     =143-1

     = 142

pogonyaev

Answer:

Stated Below:

Step-by-step explanation:

x + y = 90 because the 2 angles add up to 90 .

Now, m < x = five times  m < y, so x = 5y or y = x/5

So the last choice is the correct one.
