The answer is (C) 125. Hope this helps!
Answer:
DE = 4.24
Step-by-step explanation:
The diagram is not shown; However, the question can still be solved without the diagram.
Having said that,.
Given that
DF = EF = 3
This implies that DE is the hypothenus and will be solved using Pythagoras theorem.
DE² = EF² + DF²
Substitute 3 for EF and DF
DE² = 3² + 3²
DE² = 9 + 9
DE² = 18
Take Square Root of both sides
DE = √18
DE = 4.242640687119285
DE = 4.24 (Approximated)
Answer:
- Yes it is a right triangle
- The side lengths satisfy the Pythagorean theorem equation
Step-by-step explanation:
We can test these numbers to see if they satisfy the Pythagorean theorem equation:
15² = 9² + 12²
225 = 81 + 144 . . . . true
Since the numbers satisy the Pythagorean theorem relation, they belong to a right triangle.
____
You can recognize that the ratio of side lengths is ...
9 : 12 : 15 = 3 : 4 : 5
Further, you can recognize that the side lengths 3, 4, 5 belong to the right triangle with the smallest integer side lengths that satisfy the Pythagorean theorem. Hence the 9 : 12 : 15 triangle is similar (by a scale factor of 3) to a right triangle, thus is a right triangle.
The answer is 6.75 or 6 75/100 but you need to simplify.
Answer:
1) 8
2) -2
3) 6
Step-by-step explanation:
1) First, find the pattern in the table, with X the pattern is +1, but with Y the pattern is +2. So to find the Y-intercept in the table you need to subtract 1 from X and subtract 2 from Y. The answer is 8.
2) On a graph it is really easy, it is where the line touches the Y-axis, in this case, it is -2. The answer is -2.
3) With the equation y=mx+b, the M is the rise/run and the B is the Y-intercept, and the B in the equation is 6. The answer is 6.
