A Pythagorean triple commonly used in algebra problems is (5, 12, 13).

If vertex A is the right angle, AB = 5.

If vertex C is the right angle, AB = √(12² + 13²) = √313 ≈ 17.69.

A planned community has 150 homes, each with an automatic garage door opener. The door opener has seven switches that a homeowne
alexdok [17]

Answer:

The probability that at least two homeowners will set their switches to the same code is 100%.

Step-by-step explanation:

Consider the provided information.

The total number of code can be set with 0 or 1 is:

2×2×2×2×2×2×2=128

There are 128 different codes.  

The probability that code is unique is 1/128

Now, the probability that all codes are unique is:

[\frac{1}{128}]^{150}

Hence, the probability that all the codes are not unique is:

1-[\frac{1}{128}]^{150} \approx 1

Because the value of [\frac{1}{128}]^{150} is very small

As they can set 128 different codes and there are 150 homes. So, at least two homeowners will set their switches to the same code is 100%.

Hence, the probability that at least two homeowners will set their switches to the same code is 100%.

Can someone help asap?<br> What is the length of red segment EC to the nearest tenth?
oksano4ka [1.4K]
First you find the length of the green rectangle by using a^2 + b^2 = c^2
So that means 4^2 + 7^2 = length of green
That equals 8.1 when you square root it.
Then, you use 8.1^2 + 3^2 (which is the green rectangle height) to find the red line using the same equation
So your answer is 8.6 cm.

Evaluate the function. f(x) = 3x² – x Find f(10)​
kirill [66]

Answer:

<em>f(10)=290</em>

Step-by-step explanation:

<u>Function Evaluation</u>

Given a function f(x) as an explicit expression, finding f(x=a) implies substituting the value of x by a in every instance it occurs.

We are given the function:

f(x)=3x^2-x

It's required to find f(10). We replace the x for 10:

f(10)=3*10^2-10

Operating:

f(10)=3*100-10

f(10)=300-10

f(10)=290

Thus, f(10)=290
