Yes, 50^x = 17 is an exponential equation with base 50, and the task here is to solve it for x.

1) Take the log of both sides:  x log 50 = log 17

2) Divide both sides b log 50:    

      log 17

x = ----------

      log 50

3)  This last result can't be simplified, but can be evaluated"

x = 1.2304 / 1.6990 = 0.724 (approx.)

The probability of the given condition is 28/165.

Given that, there are four boys and eight girls in a class.

We need to find the probability of the given question.

<h3>What is probability?</h3>

The probability is defined as the chances of happening of any random event or the possibility of happening of any event is called the probability.

The teacher randomly selects three different students to answer questions.

The first is the student is a girl, the second student is a boy, and the third student is a girl.

The total number of students=12, the number of boys=4 and the number of girls=8.

Now,

Step 1: The first student is a girl=8/12

Step 2: The second student is a boy=4/11

Step 3: The third student is a girl=7/10

In the first step, you select one of 8 girls among 12 students.

In the second step, you select one of 4 boys among the remaining 11 students.

In the third step, you select one of the remaining 7 girls among the remaining 10 students.

Thus, probability=(8/12)×(4/11)×(7/10)=28/165

Therefore, the probability of the given condition is 28/165.

The height of the cylinder is 25 inches and the radius of its base is 5 inches. What is the surface area of this cylinder, in te
Vikentia [17]

ok you need formula for surface area.

SA = πrh+2πr^2

Plug in 25 and 5

SA = 2π(5)(25)+2π(5)^2

SA = 10pi*25 + 2pi(25)

SA = 250pi + 50pi

SA = 300pi

Hope this helps :)

If x-y=5 then how does y=-2x-4
mixer [17]
Based on my knowledge, you’d set both equations equal to y, and then set both sides equal to each other then solve.

y=-5+x
y=-2x-4
-5+x=-2x-4
then solve from there

(this could be completely wrong, so don’t only go by my opinion)
