3-√11
This function is evidently a quartic - a function with 4 roots. The last root has been found using the quadratic formula however, the answer always comes in pairs because the formula is
{b+√(b^2 - 4ac)}/2a and {b-√(b^2 - 4ac)}/2a. Therefore the other root must be 3-√11

A lock consist of 4 dials where each dial has 6 letters what is the probability of guessing the right combination in one try’s
VARVARA [1.3K]

Using it's concept, it is found that the probability of guessing the right combination in one try’s is of \frac{1}{1296}.

<h3>What is a probability?</h3>

A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.

In this problem, there are 4 dials, each with a \frac{1}{6} probability of getting it correct, hence the probability of getting the right combination is given by:

p = \left(\frac{1}{6}\right)^4 = \frac{1}{1296}.

Brittany graphs the point (6,3) on a coordinate grid. Which describes where she
Daniel [21]

Answer:

D. 6 units to the right and 3 units up

Step-by-step explanation:

Given

Point (6,3)

Required

Position of the point.

The general format if a coordinated grid is (x,y)

Where x and y represent the x and y axis respectively

The following conditions are to be considered when positioning a point on a coordinate grid.

1. If x is positive, then it points to the right;

2. If x is negative, then it points to the left

3. If y is positive, then it points upwards

4. If y is negative, then it points downwards

Having said this;

By comparison

x = 6 and y = 3

x and y are both positive.

Condition 1 and 3 above are satisfied.

Hence, the grid coordinates is 6 units to the right and 3 units upwards.

Option D is correct and others are incorrect

Ann [662]

<u>Complete Question: </u>

An isosceles triangle has two sides of equal length. The third side is 5 less than twice the length of one of the other sides. If the perimeter of the triangle is 23 cm, what is the length of the third side The third side is described in relation to one of the equal sides, so let x = the length of one of the equal sides. Which equation models the problem?

O x + x + (5 – 2 x) = 23

O x + x + (2 x – 5) = 23

O x + x + (2 x + 5) = 23

O X + (2 x - 5) + (2 x - 5) = 23

<u>Answer: </u>

The equation models the problem is x + x + (2 x – 5) = 23

<u>Step-by-step explanation:</u>

Given:

An isosceles triangle has two sides of equal length, so let x = the length of one of the equal sides .

The third side is 5 less than twice the length of one of the other sides. So, the third side is described as 2 x - 5.

The perimeter is the sum of the side lengths and given it as 23. Therefore, form the equation as below,

                Perimeter = x + x + (2 x-5)

Given perimeter of triangle = 23 cm. Hence,

                x + x + (2 x-5) = 23

The above equation models the given problem.
