plane
point
prism

Answers

Answer 1

Answer:
Two planes (not the same two) can intersect in a line, or
in a plane, or not at all. It depends on their orientation.

Two planes can never intersect in a single point.

If the ones digit of a number greater than 1 is 0,what factor or factors must that number have

Answers

If the units digit is zero, then you have an even number ...
' 2 ' must be one of its factors.

It must also have two or more places ... it's greater than 9.
If it had only one place, and its units digit were zero, then
the whole thing would be zero.

Since it has two or more places, 5 and 10 are also factors.

Write the equation for a parabola with the focus at(-1, 4) and the equation of the directrix x = 5.
(x + 1)2 = 3(y-4)
(y-4)2 = 12(x + 1)
(y-2)2 = -3(x – 4)
(y-4)2 = –12(x - 2)

Answers

The answer is (y - 4)2 = -12(x - 2)
Since the graph is facing the left, the starting equation would be (y - k)2 = -4p(x - h).
(h, k) is the vertex of the graph. If you plot the focus and the directrix, you can see that the distance is 6. Divide 6 by 2, thus the vertex should be 3 squares away from the focus and 3 squares away from the directrix. The vertex is (2, 4). And since the distance from the focus to the vertex and the distance from the directrix to the vertex is 3, P = 3.
Insert the numbers in and you should get the last choice.

Step-by-step explanation:

A box contains five slips of paper. Each slip has one of the number 4, 6, 7, 8, or 9 written on it and all numbers are used. The first player reaches into the box and draws two slips and adds the two numbers. If the sum is even, the player wins. If the sum is odd, the player loses.

Answers

Answer: 70% chance of winning

Step-by-step explanation: What is your question? Are you trying to ask the probability of winning? (I will assume this and answer)

The whole case of selecting to numbers : 5C2 = 5 X 4 / 2 = 10

the cases of getting a odd sum : select 1 odd number and 1 even number

=> select 1 odd number : 7 or 9 => 2 cases

=> select 1 even number: 4,6,8 => 3 cases

you multiply 2 and 3 and divide it by 2 because order doesn't matter

so the answer is 1 - (3/10) = 0.7

Final answer:

The player in the game has an equal chance of winning or losing.

Explanation:

In this problem, we are given a box containing five slips of paper, each with a number written on it. The first player draws two slips and adds the two numbers together. To determine if the player wins or loses, we need to determine if the sum of the two numbers is even or odd.

To solve this problem, we can list all the possible pairs of numbers and find out if the sum of each pair is even or odd. If the sum is even, the player wins; if the sum is odd, the player loses. We can do this by considering the possible outcomes:

(4, 6) - sum is 10 (even)
(4, 7) - sum is 11 (odd)
(4, 8) - sum is 12 (even)
(4, 9) - sum is 13 (odd)
(6, 7) - sum is 13 (odd)
(6, 8) - sum is 14 (even)
(6, 9) - sum is 15 (odd)
(7, 8) - sum is 15 (odd)
(7, 9) - sum is 16 (even)
(8, 9) - sum is 17 (odd)

From the listed outcomes, we can see that there are 5 even sums and 5 odd sums.

Therefore, the player has an equal chance of winning or losing in this game.

If the points show below are collinear, what can you conclude about the lengths AB, BC, and AC? SOMEONE PLEASE ANSWWR THIS WILL GIVE BRAINLIEST!!!!

Answers

Answer:

$\sf\nAB+BC=AC$

Explanation:

$\sf\n\textsf{This is because the lengths of line segments AB, BC and AC are the distances}\n\textsf{between the points A,B and C respectively. And since A, B and C are collinear,}\n\textsf{these distances must add up to the total distance between A and C.}$

$\textsf{Here is a simple explanation:}\n\rightarrow \textsf{Suppose you are standing at point A and you want to walk on point C. You }\n\textsf{\ \ \ \ can either walk directly to point C (along line segment AC), or you can}\n\textsf{\ \ \ \ first walk to point B and then from point B to point C (along line segments}\n\textsf{\ \ \ \ AB and BC).}$

$\rightarrow \textsf{The total distance you walk in either case is the same. So, AB+BC=AC.}$
