Answer:
m∠DEF = 90°
Step-by-step explanation:
As we know to determine the angle between two lines with the given equations or vertices we use the formula
Now we have been given the vertices of a triangle as D(5, 7) E(4, 3) F(8, 2)
To measure m∠ DEF will use the formula
Since slope of DE
Slope of EF
Now m∠DEF =
Therefore
Answer is ∠DEF = 90°
Answer:
U=21
Step-by-step explanation:
What they are asking for is U. They tell you that the cost is 481 so the C is 481
481=20u+61
You minus 61 from 481 which is 420.
420=20u
Then you divide 20 from 420 and you will get 21.
<u>Answer:</u>
The polynomial is .
<u>Explanation:</u>
Given:
Real zeros: -3,0,2
Degree 3
To Find:
The polynomial
Solution:
Now, according to given information, x = -3, x = 0 and x = 2 are zeros of equation.
Then, x – (-3) x + 3, x and x – 2 are the factors of the equation.
Now, multiply the factors, such that we will get equation.
x(x + 3)(x – 2)
