Answer:
d. parabola, 0°
Step-by-step explanation:
y² + 8x - 0
y² = -8x
Where x = cos t , y = sin t
Sin² t = -8 Cos t
1 - Cos² t = -8 Cos t
- Cos² t + 8 Cos t + 1 = 0
t = 2лπ ± (3 + √10) , л∈Z
Angle of rotation
Answer: B
Step-by-step explanation: If you multipley both 3 and 5 by the same number 4 you get the ratio 12:20
Answer:
4x - 1 and x + 6 are the factors of given Trinomial
Step-by-step explanation:
The given Trinomial is:
We can factorize this trinomial by mid-term splitting. The mid-term(23x) can be split up in two terms (24x and -x) such that their sum is 23x and their product(-24x²) is equal to the product of other two terms (4x² and -6)
So, the above expression can be written as:
Therefore, 4x - 1 and x + 6 are the factors of given Trinomial
The meaning of circumference is to find the distance around a circle or in other words the perimeter of the circle. The circumference of a circle can be calculate by using the formula C=2πr or C=πd.
In this exercise is given that a circular ice skating rink has a diameter of 65 feet, and it is asked to find its circumference. In <span>this problem the diameter of the circle is given, so in this case the formula C=</span><span>πd would be used, where d represents the diameter.
C=</span>πd
C=π(65 ft)
C=204.2 feet
The circumference of the circular ice skating rink is 204.2 feet.
Answer:
88°
Step-by-step explanation:
The names of the quadrilaterals tell you angle J corresponds to angle E. The measures of angles are not changed by rotation, which is a rigid transformation. Hence,
∠J ≅ ∠E = 88°
