F(x) = x^2 + 3 is a function.
domain of f(x) = x^2 + 3 is all real numbers.
range is all real numbers greater or equal to 3.
Answer:
D 150 ft is the length of 5 ft
None of those are correct 630
Answer:
No, it doesn't.
Step-by-step explanation:
In order to find what makes a triangle, lets use the Triangle Inequality Theorem!
This theorem can help us show whether the sum of two side lengths of a triangle is greater than the third side or not
Here is our formula(s):
1.)<em> a + b > c</em>
2.)<em> a + c > b</em>
3.) <em>b + c > a.</em>
Lets make a=12, b=7, & c=5
1.) 12 + 7 > 5
19 > 5
2.) 12 + 5 > 7
17 > 7
3.) 7 + 5 > 12
10 > 12
As you can see, both numbers 1 and 2 shows to be correct but 3 is not. Therefore it doesn't make a triangle. Remember, if <em>all</em> the two side lengths of a triangle is greater than the third side, then it makes a triangle.
Hello from MrBillDoesMath!
Answer:
23
Discussion:
In ΔABC side AC is 11, but as the triangle is isosceles the other leg also has length 11. Let the third, unknown side, be called x. Then
11 + 11 + x = Perimeter = 45.
11 + 11 + x = 45 => as 11 + 11 = 22
22 + x = 45 => subtract 22 from both sides
x = 45 -22 = 23
Thank you,
