Answer:
the answer would be 21x^3 - 12x^2y^4, because you want to multiply 3x^2 and 7x first to make 21x^3, and then multiply 3x^2 and -4y^4 to get -12x^2y^4. hope that helps!
Answer:
Step-by-step explanation:
4x^2 is the quadratic
3x is linear
-6 is the constant.
Answer:
Step-by-step explanation:
- The length of the segment JM is 25 units.
- The segment JL is between 0 and 12, so is 12 units.
- The segment KL is between 5 and 12, so is 7 units.
<u>The probabilities for each point:</u>
- P(point on JL) = 12/25
- P(point not on KL) = 1 - 7/25 = 18/25
<u>Required probability:</u>
- P = 12/25*18/25 = 216/625
Correct choice is D
The central angle measure of the sector is 4.19 rad.
<h3>Area of a Sector</h3>
You need apply the formula: for finding the area of the sector, in radians. In this formula, the variables are:
r= radius
= central angle
The question gives:
A=54 cm²
r= radius= 9cm
Thus, the central angle will be:
For =3.14159..., you have :
