Answer:

Step-by-step explanation:
To calculate the lenght of the diagonal d across the square, we can assume that the square it is compound of two right triangles. So, we can resolve this exercise using The Pythagorean Theorem.
<em>The Pythagorean theorem</em> states that in every right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the respective lengths of the legs. It is the best-known proposition among those that have their own name in mathematics.
If in a right triangle there are legs of length a and b, and the measure of the hypotenuse is c, then the following relation is fulfilled:
a is the height, b is the base, and c is
the hypotenuse.
To obtain the value of the hypotenuse

To find the value of the lenght of the diagonal d across the square, we have:
Where a = b = 20
Substituting the values

Round the answer to 2 decimal places

Answer:
vertex = (2, - 9 )
Step-by-step explanation:
Given a quadratic in standard form : ax² + bx + c : a ≠ 0
Then the x- coordinate of the vertex is
= - 
x² - 4x - 5 ← is in standard form
with a = 1, b = - 4, thus
= -
= 2
Substitute this value into the quadratic for corresponding value of y
(2)² - 4(2) - 5 = 4 - 8 - 5 = - 9
vertex = (2, - 9 )
The y-intercept of 1000 in the graph is at the point where x is equal to 0.
At
, it means no month have passed. It is the initial point where Zen deposited the money.
What is the amount (y axis)? 1000!
So y represents the initial deposit of Zen, which is 1000.
ANSWER: Answer choice D (Amount of money Zen deposited in the savings account)
<h3>Answer: independent </h3>
Reason:
Each cube doesn't affect the other one, which means that the probabilities are not altered. This is assuming that the cubes don't bump into each other when rolling on the table. So either there's enough space on the table, or they take turns one at a time.
