A shop sells chocolate, vanilla and strawberry ice cream cones. In one day, 45% of the ice cream cones sold are vanilla and 17%
True [87]

Answer:

950

Please help with this math homework question below.

<u>Given</u>:

The given equations are -6 x+4 y=22 and y=11-4 x

We need to determine the pair of numbers that is a member to the system of equations.

<u>Pair of numbers:</u>

The pair of numbers can be determined by solving the system of equations.

Let us use the substitution method to solve the equations.

Substituting y=11-4 x in the equation -6 x+4 y=22, we have;

-6 x+4 (11-4x)=22

  -6 x+44-16x=22

             44-22x=22

                  -22x=-22

                        x=1

Thus, the value of x is 1.

Substituting x = 1 in the equation y=11-4 x, we get;

y=11-4(1)

y=11-4

y=7

Thus, the value of y is 7.

Hence, the pair of numbers that is a member of both the equations are (1,7)

For any number n&gt;1 is |(3/4+2/3i)^n|
sasho [114]

The for any number n>1 is |(3/4+2/3i)^n| greater than 1 after simplifying the complex number.

<h3>What is a complex number?</h3>

It is defined as the number which can be written as x+iy where x is the real number or real part of the complex number and y is the imaginary part of the complex number and i is the iota which is nothing but a square root of -1.

We have a complex number:

= \rm |(\dfrac{2}{3}+\dfrac{3}{4}i)^n|\\\\\\= \rm |(\dfrac{8+9i}{12})^n|\\\\\\= \rm |\dfrac{(8+9i)^n}{12^n}|\\\\

Here n>1

Plug n = 2

= \rm |\dfrac{(8+9i)^2}{12^2}|\\\\

= 145/144

= 1.0069

Which is greater than 1.

Thus, the for any number n>1 is |(3/4+2/3i)^n| greater than 1 after simplifying the complex number.
