Which of the following planes is parallel to ABCD
Answer:
P

:4x−2y+6z=3
P
2
=4x−2y−2z=6
P
3
=−6x+3y−9z=5
P

=2x−y−z=3
Step-by-step explanation:
The coefficients of each x,y,z give the direction vector of the normal vector of the plane.
Parallel but not identical condition will be that:

Answer:
non-linear, y = -6, x = 2 & x = 6, y = 2 & x = 4, above.
Step-by-step explanation:
The graph is not a straight line so that means that it is linear.
The y-intercept is the point at which the function touches the y-axis, which is at the coordinate point (0, -6), so y = -6.
The x-intercepts are the points at which the function touches the x-axis, which is at x = 2 and x = 6.
The highest y value is y = 2, and it happens when x =4.
Between x = 2 and x = 6, the function is above the x-axis line, so that means it must be above 0.

Answer:
D. f^-1(x) = x^3 +15
Step-by-step explanation:
The inverse of ...
y = f(x)
is ...
x = f(y)
Solving this for y gives ...
x = ∛(y -15)
x³ = y -15 . . . . . . . . cube both sides
x³ +15 = y . . . . . . . add 15
The inverse function is ...
f^-1(x) = x³ +15

Answer:
x=70⁰
Step-by-step explanation:
a line equals 180⁰ so you subtract 110⁰ from 180⁰ and it gives you 70⁰

Answer:
(-10)+3 1/2 = -6 1/2
Step-by-step explanation:
It first points to the left. Which means subtracting. It shows that it starts at zero so, keep that in mind. Then it points to the right which means your adding 3 1/2. So you would start at zero and subtract 10. (-10). Then you would add 3 1/2. +3 1/2
(-10) + 3 1/2
To then make -6 1/2
If three circular metal discs of equal thickness whose radii are 5cm, 20cm and 40cm are melted down to form one circular disc of the same thickness, find its radius.
Answer: 45 (cm)
Step-by-step explanation:
Since the discs have the same thickness, we will think about the areas.
Let say x the new radius:
[tex]\pi*5^2+\pi*20^2+\pi*40^2=\pi*x^2\\\Longrightarrow\ 5^2+20^2+40^2=x^2\\\\\Longrightarrow\ 2025=x^2\\\\\Longrightarrow\ x=\sqrt{2025} =45[/tex]
Which set of numbers is contained in the set of rational numbers?
A Whole Numbers
B Natural Numbers
Integers
D
all of the above
Answer:
All of the above.
Step-by-step explanation:
All whole numbers are rational numbers. For example 5 can be be expressed as 5/1 thus a rational number.All integers are whole numbers thus they are all rational numbers.All natural numbers are rational numbers. For example, 5 is a natural number and can be expressed as 5/1 which is a rational number.WORTH MANY POINTS PLEASE HELP!!!
A coffee shop uses the formula P=C+1/2S to calcuate the number of loyalty points a customer has earned after buying C coffees and S sandwiches.
a. If Pete has 32 loyalty points after buying 23 coffees, then how many sandwiches has he bought?
b. If Morgan has 22 loyalty points after buying 14 sandwiches, then how many coffees has she bought?
Answer: a.) Pete bought 18 sandwiches.
b.) Morgan bought 15 coffees.
Step-by-step explanation: The formula P = C + 1/2S lets us know that sandwiches are worth half as many points as coffees.
a. If Pete has 32 loyalty points after buying 23 coffees, then how many sandwiches has he bought?
Plug in the number of points (P) and the number of coffees (C).
32 = 23 + 1/2S
subtract 23 from each side of the equation.
9 = 1/2S
Now. to solve for S, multiply each side by 2.
18 = S
Pete bought 18 Sandwiches.
b. If Morgan has 22 loyalty points after buying 14 sandwiches, then how many coffees has she bought?
The same method can be used for problem b.
Plug in the number of points (P) and the number of sandwiches (S).
22 = C + 1/2 (14)
Multiply 1/2 by 14.
22 = C + 7
To solve for C, subtract 7 from each side of the equation.
15 = C
Morgan Bought 15 coffees.

Hi! I'm happy to help!
A square root, means:
√x=y
This means that:
x=y·y=√x·√x
When we have the square button, it causes everything to be multiplied by itself once.
√x²=x
Due to the fact that the squared symbol is outside of the parenthesis, it causes both the square toot of 2, and the square root of 3, to be squared.
Now that we know this, √2², and √3²= 2, and 3.
This is why we get 2+3.
2+3=5, which is pretty self explanatory.
I hope this was helpful, keep learning! :D

write a function to repaint this. reflection across the y axis, then a translation a units to the right and b units up
Answer:
For the first one, I believe you would need to use a rotation matrix; to rotate 90º counterclockwise, the matrices would look like ; you would then multiply those out. A reflection across the x-axis would be changing the sign of f(x) (from negative to positive or positive to negative), a reflection across the y-axis would be changing the sign of x, translation a units to the right would be subtracting a from x, translation b units up would be adding b to x. Rotation of 180º about the origin would be the same format as the first matrix, except it would be cos180 and cos0 on the top and sin180 sin0 on the bottom. Reflection across the y-axis would be changing the sign of x again.
OR
1. We know that, 'Translation shifts the figure in any direction'.
As, the function f(x) is translated 'a' units to the right, the new form of function is f(x-a).
Again, the function is translated 'b' units up, the final form of the function is f(x-a)+b.
2 and 3. We know that, ' Reflection flips the image over a line'.
As the function g(x) is reflected over y-axis, the new form of the function is g(-x).
As the function h(x) is reflected over x-axis, the new form of the function is -h(x).
4 , 5 and 6. We know that, 'Rotation turns the image around a point to a certain degree'.
Let us assume the function to be a point (x,y).
As the function is rotated by 90° counterclockwise about the origin, the new function becomes ( y,-x ) i.e. R_{90}R
90
(x,y) = ( -y,x ).
As the function is rotated by 180° counterclockwise about the origin, the new function becomes ( y,-x ) i.e. R_{180}R
180
(x,y) = ( -x,-y ).
As the function is rotated by 2700° counterclockwise about the origin, the new function becomes ( y,-x ) i.e. R_{270}R

What is the distance between these two points?
Answer:
Step-by-step explanation:

Answer: sqrt 145
Step-by-step explanation:
(2,7) (-6,-2)
d = sqrt [(x-x)^2+(y-y)^2]
d = sqrt[(-6-2)^2+(-2-7)^2]
d = sqrt(8^2 + -9^2)
d = sqrt (64+81) = sqrt 145
Find the lengths of LM⎯⎯⎯⎯⎯⎯ and PQ⎯⎯⎯⎯⎯ and determine whether they are congruent.
Hint: Congruent line segments have the same length.
Answer:
The fourth option is the answer.
Step-by-step explanation:
Use distance formula
[tex] {x}^{2} + {y}^{2} = {d}^{2} [/tex]
where x is the distance between the two endpoints of the congruent line segment and y is the distance between the congruent line segment.
[tex] {3}^{2} + {6}^{2} = 45[/tex]
Set 45 equal to d^2.
[tex]45 = {d}^{2} [/tex]
[tex] \sqrt{45} = d[/tex]
[tex]3 \sqrt{5} = d[/tex]
L and M have the same distance between points as well. so they are congruent.

X+2y, if X=-2 and Y=4
Answer:
6
Step-by-step explanation:
X=-2
Y=4
X+2y
= -2 + 2(4)
= -2 + 8
= 6
the answer is:
6
because:
X=-2
Y=4
X+2y
= -2 + 2(4)
= -2 + 8
