Answer:
Dilation by a scale factor of fraction 1 over 2 followed by reflection about the x-axis.
Step-by-step explanation:
We are given to select the set of transformations that has been performed on triangle PQR to form triangle P'Q'R'.
From the graph, we note that
the co-ordinates of the vertices of triangle PQR are P(-4, 2), Q(0, 0) and R(2, 6).And, the co-ordinates of the vertices of triangle P'QR' are P'(-2, -1), Q'(0, 0) and R'(1, -3).
Let the dilation factor applied on triangle PQR to form triangle P'Q'R' be represented by d.
Then, we observe that
1/2 × P(-4,2)=(-2,1),
1/2 × Q(0,0)=(0,0),
1/2 × R(2,6)=(1,3).
So, the value of d will be
d = 1/2.
Again, to arrive at the vertices of triangle P'Q'R', we need to change the sign before the y co-ordinates ((x, y) ⇒ (x, -y)) of each new vertex hat we found after dilation.
That is.(-2, 1) ⇒ P'(-2, -1),
(0, 0) ⇒ Q'(0, 0),
(1, 3) ⇒ R'(1, -3).
This is reflection over X-axis.
Therefore, the set of transformation is given by
Dilation by a scale factor of fraction 1 over 2 followed by reflection about the x-axis.
A survey asks 184 people "What beverage do you drink in the morning?", and offers choices:
• Coffee only
• Tea only
• Both tea and coffee
• Neither tea nor coffee
Suppose 52 report tea only, 44 report coffee only, and 68 report both.
what is the question?
In triangle PQR if PQ = QR then which one of the following relation is TRUE? *
∡P < ∡R
∡P = ∡ Q
∡ P = ∡ R
∡ P is greater than ∡R
Answer:
Triangle PQR is an isoceles triangle since PQ=QR, where angle P= angle R (property of isoceles triangle)

What value of a makes the solution to the equation 5x-10=3x+a equal to 12
Answer:
a=-1.2
Step-by-step explanation:
5x-10=3x+a=12
let's first find x:
5x-10=12
add 10 to both sides:
5x=22
divide both sides by 5:
x=4.4
now that we know what x is, we can plug it back into the equation to find a:
3*4.4+a=12
first, simplify both sides:
13.2+a=12
then, subtract 13.2 from both sides:
and our answer is: a=-1.2

Which of the following is an example of a Durable good?
A Volvo
The rights to a song.
O Dog training
O A Twinkie
Answer:
A Volvo
Step-by-step explanation:
A "good" is something you can touch. Song rights and dog training are not "goods". It is durable if it has a long life.
A Twinkie may have a shelf life approaching that of a Volvo, but food (or what passes for food) is not considered durable, in general. Rather, it is considered consumable.
A Volvo is an example of a durable good.

Find an equation of the circle and sketch it if it has: Center on y=4, tangent x-axis at (–2, 0)
Answer:
[tex](x+2)^2+(y-4)^2=16[/tex]
OK, lets start by drawing a basic graph (the first one) so we can visualize.
We already know that the y coordinate of the circle's center is [tex]4[/tex].
We know that the circle is tangent to the [tex]X[/tex] axis at [tex](-2,0)[/tex]
That means the x coordinate of the center has to be [tex]-2[/tex], as the tangent is a point on the edge of the circle that touches a line at exactly one point.
The radius is the distance from the center of the circle to its edge. We know the center's location now, it is [tex](-2, 4)[/tex] and a point on the edge of the circle (the tangent point) which is [tex](-2,0)[/tex]. so the distance between the points is 4 which is the radius (you can use the distance formula, but it's quite oblivious.)
We can imagine the circle should look like this (the second one):
Now we can piece together an equation
The equation of a circle is [tex](x-h)^2+(y-k)^2=r^2[/tex] where [tex](h,k)[/tex] is the center and [tex]r[/tex] is the radius. When we put the numbers in: we get [tex](x-(-2))^2+(y-(4))^2=4^2[/tex] which can be simplified into [tex](x+2)^2+(y-4)^2=16[/tex] which is the answer.
