Simplify i^38 ????????
stich3 [128]

Answer:

i is defined as the square root of -1.

i^2 = -1

i^3 = -i

i^4 = 1

Following the pattern, we see that i^40 = 1, so i^38 is two above, or equal to -1.

So, i^38 = -1.

Let me know if this helps!

If you wanted to vertically stretch the graph of F(x) = |x| by five units, what would the equation of the new function, G(x), be
zheka24 [161]

Solution:

The Preimage function is , F(x)=|x|

Consider a point (a,b) on the function, F(x)=|x|. it means

b=|a|-----(1) satisfies the function.

Now the function F(x)=|x|  is vertically stretched by 5 units.It means

x=a , y= b+5

x=a, b=y-5

So, putting the value of a and b in equation (1).

y-5=|x|

y= |x| + 5 is vertical stretch of y= |x| by 5 units.

A 4-digit PIN number is selected. What it the probability that there are no repeated digits?
geniusboy [140]

Answer:

P(A)=0.504 or 50.4%

Step-by-step explanation:

The <em>probabilities</em> constitute a branch of mathematics that deals with measuring or quantitatively determining the possibility that an event or experiment produces a certain result. The probability is based on the study of combinatorics and is the necessary foundation of statistics.

A <em>permutation</em> is an ordered arrangement of objects in a group, without repetitions.

A 4-digit PIN is selected. What is the probability that there are no repeated digits?

First, there are only 10 possible values for each digit of the PIN (0, 1, 2, 3, 4, 5, 6, 7, 8, 9). The total possibles 4 PINs are 10^{4} =10000

There's no repeated numbers and all the four numbers have to be different, which means we have to select 4 numbers out of 10 numbers. Using the permutation equation nP_{k} =\frac{n!}{(n-k)!}

10P_{4} =\frac{10!}{(10-4)!}=10.9.8.7.6= 5040

So, the probability that there are no repeated digits is:

P(A)=favorable cases/possible cases

P(A)=\frac{5040}{10000}=0.504 or 50.4%

Solve the system of linear equations by substitution. y=2x+5 and y=3x-1
Doss [256]
Plug in the second equation into the first equation for y.
y = 2x + 5 \\ y = 3x - 1 \\ 3x - 1 = 2x + 5
Now put the variable on one side and constants on the other
3x - 1  + 1 - 2x = 2x - 2x + 5 + 1 \\ x = 6
Now plug that back into one of the original equations
y = 2x + 5 \\ y = 2(6) + 5 \\ y = 12 + 5 \\ y = 17
So now you know
x = 6 \\ y = 17
Its always a good idea to check
17 = 2(6) + 5 \\ 17 = 17 \\ 17 = 3(6) - 1 \\ 17 = 17
