Talja [164]3 years ago

Answer:

7020

Step-by-step explanation:

The letter could be any 1 of the 26 and it could be placed in any 1 of 3 places so this makes 26*3 = 78 possibilities.

For each of these  there is any one of  permutations of 2 digits from 10

= 10P2 = 10! / 8! = 10*9 = 90.

So the answer is 78 * 90 =  7020.

Note I am assuming that the 2 digits picked are different - no duplicates.

please mark me brainliest!

How can i find The function of f(x) = 150 (1.3)^t
natka813 [3]

Answer:

See below.

Step-by-step explanation:

In comments, you said you wanted it graphed.

If it says f(x) on the left side, the equation should have an 'x' on the right side, so something is fishy here.

But, in an effort to try and help you ....

With the data you have given, I would graph it just like y = 150 (1.3)^x

You can pick various values for x, like -3,-2,-1,0,1,2,3 and see what y is for each one, then plot the points on graph paper.

If x = 0, y= 150(1.3)^0 = 150(1) = 150  because anything to power zero is 1

If x = -1, y= 150(1.3)^(-1) = 150(1/1.3) ≈ 132.7

If x = +1, y= 150(1.3)^(1) = 150(1.3) = 195

And so on.

I did the graph on DESMOS and it has a very large scale.

after two years on the job, an engineer salary was $60,000. after seven years on the job, her salary was $66,000. let y represen
galina1969 [7]

Answer: y = 1200m + 57,600

Step-by-step explanation: To be a line, let's say that x is the numbers of years on the job and y the salary.

So, we have (2,60000) and (7,66000)

y = mx + b

66000 = 7m + b

60000 = 2m + b (-)

________________________

6000 = 5m

m = 6000/5 = 1200

60000 = 2m + b

60000 = 2.1200 + b

60000 = 2400 + b

b = 60000 - 2400

b = 57600

y = mx + b

y = 1200m + 57,600
