3 times the square root of 28??
3√28

Answers

First of all, the square root of 28 is 5.3. That is because 5.3*5.3=28.09 but mainly just 28. So now that we know what the square root of 28 is now we can multiply it by 3.

5.3*3= 15.9

Your final answer is 15.9

If f(x)=x^2+x and g(x)=x-3, find f(g(7)).

Answers

Answer:

A. 20

Step-by-step explanation:

First we need find X.
x = 7 (because we see question). f(g(7))
Now we find g(x) = x - 3 => g(x) = 7 - 3
Next we find f(x) = x² + x . We have f(4)
f(4) = 4² + 4
= 20

Which special version of the Pythagorean Theorem can you use to find the length of any square's diagonal, d, using only the length of its side, s?

Answers

Using the Pythagorean Theorem, the length of a square diagonal, in function of it's sides s, is given by:

$d = s√(2)$

The Pythagorean Theorem relates the length of the legs $l_1$ and $l_2$ of a right triangle with the length of the hypotenuse h, according to the following equation:

$h^2 = l_1^2 + l_2^2$

In a square, as given in the figure below, the legs are the sides s, of equal measure, while the hypotenuse is the diagonal d, thus:

$d^2 = s^2 + s^2$

$d^2 = 2s^2$

$d = √(2s^2)$

$d = s√(2)$

A similar problem is given at brainly.com/question/21691542

the square's diagonal is the triangle's hypotenuse.

the original Pythagorean theorem is $a^(2) + b^(2) = c^(2)$ where a and b are the two sides and c is the hypotenuse.

that means the Pythagorean theorem for this question is:

$s^(2) + s^(2) = d^(2)$ or $2( s^(2) )= d^(2)$

A woman put $580 into a saving account for one year . the rate of interest on the account was 6 half %. how much was the interest for the year in dollars and cents?

Answers

I don't know about American currency but, I think it is $617 and 70 cents like $617.70.

6.5% = 6.5/100 = 0.065
0.065 x 580 = 37.7
$580 + $37.70 = $617.70
