Find the equation of the parabola whose vertex is the origin and whose directrix is x=-4
Answer:
D
Step-by-step explanation:
2020 2021
Equation of the parabola whose vertex is the origin and whose directrix is x=-4 is x=0.
What is Parabola?A parabola is a curve where any point is at an equal distance from: a fixed point (the focus ), and; a fixed straight line (the directrix )
As we have vertex at the origin i.e. (0,0) and directrix is x=-4 and a line parallel to y-axis,
it must have a focus at (4,0)
Equation of the parabola represents locus of a point (x, y), which moves so that its distance from x=-4 to (4,0) are equal.
Hence, equation of parabola is
(x-4)²+(y-0)²=(x+4)²
(x-4)²+y²=(x+4)²
x²+16-8x=x²+16+8x
-16x=0
x=0
Hence, equation of the parabola whose vertex is the origin and whose directrix is x=-4 is x=0.

3 dice of different colors are rolled, and the number coming up on each die is recorded. how many different outcomes are possible?
When rolling three different dice, the number of possible outcomes can be calculated by performing 6*6*6, which equals 216, as there are 6 possible results on each die.
Explanation:The question pertains to the count of distinct outcomes when rolling three differently colored dice. Each die has 6 possible outcomes (numbered 1 to 6). Since these are independent events, you multiply the number of outcomes of each event (or the number of outcomes of each die's roll) to get the total number of different outcomes for all the events combined. Hence, the total different outcomes would be 6*6*6 = 216

Find z so that 6% of the standard normal curve lies to the left of z. remember that this means you are looking for the area (which means you need to find the 4 digit number in the area portion of table 3 that is closet to 6%).
We can solve this problem by referring to the standard normal probabilities table for z statistic.
At P = 0.06 to the left of z, this corresponds to a value of approximately z = -1.55

Solve 2 cos theta + 2 = 3 in the interval from 0 to 2pi. Round to the nearest hundredth.
Final answer:
The solutions to the equation 2 cos θ + 2 = 3 in the interval from 0 to 2π are θ = π/3 and θ = 5π/3, which approximate to 60 degrees and 300 degrees.
Explanation:
The equation given is 2 cos θ + 2 = 3. To solve this equation, first subtract 2 from both sides to get 2 cos θ = 1. Then, divide both sides of the equation by 2 to isolate cos θ, yielding cos θ = 0.5.
In the interval from 0 to 2π (0 to 360 degrees), cos θ = 0.5 occurs at θ = π/3 and θ = 5π/3 (60 degrees and 300 degrees), as these are the angles in the first and fourth quadrants where the cosine value is positive and equal to 0.5.
Therefore, the solutions to the equation are θ = π/3 (θ ≈ 1.05 radians) and θ = 5π/3 (θ ≈ 5.24 radians), or θ ≈ 60 degrees (θ ≈ 1.05) and θ ≈ 300 degrees (θ ≈ 5.24) when rounded to the nearest hundredth of a radian.

A rectangle has an area of 102 cm2. The length of the rectangle is 17 cm.
What is the perimeter of the rectangle?
Answer:
(Really really really sorry if this incorrect)... ok so it's 17 cm tall in length. That would be 17 blocks high, for example. The area is 102, so 102 cm2 divided in half equals 51, so the width would be 51 cm. So the perimeter is 17 + 17 + 51 + 51 = 136 cm.
