Find the area of a square with diagonals of length 9root2<br>

igomit [66]

Answer:

$A=162$

Step-by-step explanation:

The are of a square is $A=a^{2}$ so 9 root 2 is $9\sqrt{2}$ since the formula says that a need to be squared so we need to square 9 root 2 $(9\sqrt{2})^{2}$ which would be $162$ or another way would be to turn 9 root 2 into a decimal $9\sqrt{2} = 12.727292206...$ then you would square that number just like we did in the first example $(12.7272206)^{2}$ which would give you $161.98$ then all you have to do is round to the nearest tent then you would get $162$ as an answer

i would agree that this step requires to much work so just stick with the first way to do it.

thank you for waiting for this answers i hope it helps a lot i went into details to make sure that you understand if you still don't get it just post another question ill be more than happy to help you out.

Write the simplest polynomial function with the given roots 2i, square root of 3, and 4

Volgvan

Answer:

y = (x - 4)(x + 2i)(x - 2i)(x + √3)(x - √3) Possible answer
y = (x - 4)(x^2 + 4)(x^2 - 3) Possible answer

Step-by-step explanation:

The simplest answer is that 2i cannot be a lone root. It must have a twin that is - 2i

√3 has the same sort of rule. It cannot be a root all by itself. It also must have a twin, in this case -√3

So the answer must be

(x - 4)(x + 2i)(x - 2i)(x + √3)(x - √3) <<< Possible answer

but this can be reduced even further.

(x + 2i)(x - 2i) = x^2 - x*2i + x*2i - 4i^2
(x + 2i)(x - 2i) = x^2 - 4(i)^2
(x + 2i)(x - 2i) = x^2 + 4. Remember i^2 = - 1

By a similar method (x - √3)(x + √3) = x^2 - 3

So the polynomial is reduced to

(x - 4)(x^2 + 4)(x^2 - 3) <<<< Answer

If this is not among your answers and the factored form is not either, please tell me what is.

Answer this question Angie and her friends are 3/4 of a pizza.Her brother joe ate 2/3 of what was left.How much did joe eat?

Alja [10]

If Angie and her friends ate 3/4 of a pizza, that means that 1/4 is left.
Joe ate 2/3 of 1/4 of a pizza. To find out how much he ate, multiply 1/4 by 2/3.

$\frac{1}{4}* \frac{2}{3}= \frac{2}{12}$ because you multiply fractions straight across.

Your answer is 2/12 or <em>1/6 of the pizza</em>

3.5 hours: $10 1/2 hour: $1.25. which is the better deal

andrey2020 [161]

3.5 hours: $10 because if a 1/2 hour equaled 1.25 : 3.5 hours would give you $7.75
