Answers

Answer 1

Answer:

-k

Step-by-step explanation:

Cos(140)=cos(180-40)=-cos(40)=-k

Answer 2

Answer:

Step-by-step explanation:

Sin (90 - A)  = Cos A

Cos (90 + A) =   -Sin A

Sin 50 = Sin (90 - 40)

          = Cos 40

         = k

Cos 140 = Cos (90 + 50)

             = - Sin 50

            = (- k)

The first and second steps to solve the equation 3x/5+5=20 are shown below

Answers

Answer:

The solution of the equation is:

x = 25.

Step-by-step explanation:

To solve the equation:

[tex]\frac{3x}{5}+5=20[/tex]

First, you must add the terms 3x/5 and 5:

[tex]\frac{3x+25}{5}=20[/tex]

Now, you pass the number that is dividing (5), to multiply to the other side of the equality and operate:

3x + 25 = 20 * 53x + 25 = 100

Next, you pass the number that is adding (25), to subtract to the other side of the equality and operate:

3x = 100 - 253x = 75

At last, you pass the number that is multiplying the unknown variable, to divide to the other side of the equality and operate:

[tex]x=\frac{75}{3}[/tex]x = 25

If we use this value in the original equation, we can prove if it's the correct:

[tex]\frac{3x}{5}+5=20[/tex][tex]\frac{3*25}{5}+5=20[/tex][tex]\frac{75}{5}+5=20[/tex][tex]15+5=20[/tex]20 = 20

As you can see, the result x = 25 is the correct.

x=5*sqrt(2)/2

Step-by-step explanation:

since it is a right triangle, and one of the other angles is 45, we know that the last angle must also be 45 since the 3 interior angles must be 180

then using pythagroem theorem

sqrt(a^2+b^2)=c

sqrt(x^2+x^2) = 5

square both sides

x^2+x^2=25

2x^2=25

x^2=25/2

square root both sides

x= sqrt(25/2)=5/sqrt(2)

rationalize the demonominator by multiplying by sqrt(2)/sqrt(2)

x=5*sqrt(2)/2

The expected (mean) life of a particular type of light bulb is 1000 hours with a standard deviation of 50 hours. The life of this world is normally distributed what is the probability that a randomly selected bulb would last fewer than 940 hours?

Answers

Answer:

11.5%

Step-by-step explanation:

To solve this problem, we can use the knowledge that there are z score tables that calculate probabilities based on z scores. Thus, we must calculate the z score.

The z score formula is [tex]\frac{x- m}{s}[/tex] , where x is the value, m is the mean, and s is the standard deviation. We can then plug our values in to get [tex]\frac{940-1000}{50} = \frac{-60}{50} = -1.2[/tex] as our z score. Plugging this into a table where table values represent the area to the left of the z score (as we want to calculate everything under 940), we get 0.115, or 11.5% as our answer
