Sole the equation for the indicated variable. zm= a+b/a, for a

Mathematics

Lena [83]3 years ago

zm= a+b/a, for a

Switch sides to have a on left side


a+b/a=zm


Now multiply both sides by a


A+b= zm(a)


A+b= ama


Now subtract azm both sides


A+b-azm=0


Subtract b both sides

A-azm= -b


Factor out a from ask


A(1 -zm)= -b


Divide each term by 1 - zm to get


A= - b/1-zm

The population of a small town is decreasing exponentially at a rate of 14.3% each year. The current population is 9,400 people.
KonstantinChe [14]

Using an exponential function, the inequality is given as follows:

9400(0.857)^t < 6000

The solution is t > 2.9, hence the tax status will change within the next 3 years.

<h3>What is an exponential function?</h3>

A decaying exponential function is modeled by:

A(t) = A(0)(1 - r)^t

In which:

  • A(0) is the initial value.
  • r is the decay rate, as a decimal.

For this problem, the parameters are given as follows:

A(0) = 9400, r = 0.143.

The population after t years is modeled by:

A(t) = A(0)(1 - r)^t

A(t) = 9400(1 - 0.143)^t

A(t) = 9400(0.857)^t

The tax status will change when:

A(t) < 6000

Hence the inequality is:

9400(0.857)^t < 6000

Then:

(0.857)^t < \frac{6000}{9400}

\log{(0.857)^t} < \log{\left(\frac{6000}{9400}\right)}

t\log{0.857} < \log{\left(\frac{6000}{9400}\right)}

Since both logs are negative:

t > \frac{\log{\left(\frac{6000}{9400}\right)}}{\log{0.857}}

t > 2.9.

The solution is t > 2.9, hence the tax status will change within the next 3 years.

If GH has endpoints G(-8, 1) and H(4, 5), then the midpoint M of GH lies on the line y=-x+1
Gnoma [55]
The midpoint of GH is (-2, 3), and that point satisfies the equation because

3 = -(-2) + 1
3 = 2 + 1
3 = 3

Sophia scored 92 percent in a math test. If the test had 50 questions, how many did she get right?
USPshnik [31]

Answer:

Sophia got 46 questions right.

Step-by-step explanation:

Heres why:

In order to find how much she got right, we put 92% over 100 and make it a fraction so that would be 92/100.

Now, she had 50 questions. So, we will put that over 1. So that would look like this: 50/1.

Finally, we multiply: 92/100 times 50/1.

This equals 4600/100 which equals 46

SO: Sophia got 46 questions right! Hope this helps and plz mark brainliest if you want to!  :)
