Masteriza [31]3 years ago
5 0

Answer:

2 sqrt(5) =x

Step-by-step explanation:

We can use the Pythagorean theorem since this is a right triangle

a^2 + b^2 = c^2

2^2 +4^2 = x^2

4+16 = x^2

20 = x^2

Take the square root of each side

sqrt(20) = sqrt(x^2)

sqrt(4*5) = x

sqrt(4) sqrt(5) =x

2 sqrt(5) =x

What is the simplified form of 162
SashulF [63]

Answer:

9 √ 2

Step-by-step explanation:

1. Rewrite  162 as 9^{2}    ⋅2  

2.  factor 81 out of 162

          \sqrt{81 (2)}

3.  Rewrite 81 as 9^{2}

          \sqrt{9^{2}.2 }

4. Pull the terms from under the radical

          \sqrt[9]{2}

I hope this helps :)

The sale price of an item is $180 after a 25% discount is applied. What is the original price of the item?
Valentin [98]
So
100%=original
25% discount
100-25=75
it is 180 sale
75%=180
find 100%

a hack is to recognize that 75/3 times 4=100 so
75%=180
divide 3
25%=60
times 4
100%=240


the real way is proportions
75:180 =100:x
75/180=100/x
multiply both sides by 180x
75x=18000
divide 75
x=240



origitnal price=$240

1. The total area within any continuous probability distribution is equal to 1.00.
olchik [2.2K]

Answer:

1. True

2. False.

3. True.

Step-by-step explanation:

1. The total area within any continuous probability distribution is equal to 1.00: it is true because the maximum probability (value) is one (1), therefore, the total (maximum) area is also one (1).

<em>Hence, for continuous probability distribution: probability = area</em>.

2. For any continuous probability distribution, the probability, P(x), of any value of the random variable, X, can be computed: False because it has an infinite number of possible values, which can not be counted or uncountable.

<em>Hence, it cannot be computed. </em>

3. For any discrete probability distribution, the probability, P(x), of any value of the random variable, X, can be computed: True because it has a finite number of possible values, which are countable or can be counted.

<em>Hence, it can be computed. </em>

When analyzing three linear functions, Michele noticed that they all intersected at the point (5, 3). What conclusion can Michel
qwelly [4]

Answer:

The linear function with the smallest slope must be multiple of one of the other two linear functions if all functions are coplanar. Otherwise, they intersect at the given point in space.

Step-by-step explanation:

A system of two linear functions with two variables have an unique solution on a given plane, as there are three linear function, it means that linear function with the smallest slope must be multiple of one of the other two linear functions.

But, if those functions are not all coplanar and have 3 variables, they intersect at the given point.

Please helpppppppppp<br> include step by step
balandron [24]

Answer:

507

Step-by-step explanation:

As they said, I will be using 3 as pi.

3 (pi) * (\frac{26}{2})^2 (radius squared)

Without annotations: 3*\frac{26}{2}^2

3*\frac{26}{2}^2

3*13^2; 13*13=169

3*169
