How to solve this problem

Eddi Din [679]

Answer:

Solving the radical $\pm\sqrt{-81}$ we get $\mathbf{\pm9 \ i}$

Step-by-step explanation:

We need to express the radical $\pm\sqrt{-81}$ using the imaginary unit i

Prime factors of 81 are: 3x3x3x3

and $\sqrt{-1}=i$

Solving:

$\pm\sqrt{-81}\\=\pm\sqrt{81}\sqrt{-1}\\=\pm\sqrt{3\times3\times3\times3}i\\ =\pm\sqrt{3^2\times3^2}i\\=\pm3\times3\ i\\=\pm9 \ i$

So, Solving the radical $\pm\sqrt{-81}$ we get $\mathbf{\pm9 \ i}$

How do you multiply and then use distributive property?

morpeh [17]

It depends on the question given, for example

you can do distributive property will multiplying.

Example 1:

there is two ways on doing distributive property.

I can do 4(8+3)

add 8+3 since it is inside the parenthesis which equals = 11 then multiply the outside on what you added. 4x11= 44

example 2: I can also do it another way. 4(8+3) distribute the 4 by multiplying the 4 with both numbers. 4x8 and 4x3 which equals 32, and 12. add 32+12=44

so either way you will get the same answer. hope I helped.

For the final days before the election, the campaign manager has a total of $41,500 to spend on TV and radio campaign advertisem

Margaret [11]

Answer: There are 9 T.V. and 29 radio ads.

Step-by-step explanation:

Since we have given that

Total amount spend on TV and radio = $41,500

Total number of voters using the allocated funds = 148,000

Let the number of TV be 'x'.

Let the number of radio ads be 'y'.

Cost of each TV = $3000

Cost of each radio ads = $500

Number of voters see T.V. = 10,000

Number of voters use radio = 2000

So, According to question, it becomes,

$3000x+500y=\$41500\implies\ 30x+5y=415\\\\10000x+2000y=148000\implies 10x+2y=148$

Using the graphing method, we get that

These two lines are intersect at (9,29).

Hence, there are 9 T.V. and 29 radio ads.
