For the graphed function f(x) =(2)^x +2 +1. Calculate the average rate of change from x = -1 to x= 0
Answer:
B. 2.
Step-by-step explanation:
You can find the average by substituting the given values in the function, then do an arithmetic average with results.
So, for X = - 1 you get f(-1) = 1
For X = 0 you get f(0) = 3
So, the average with 1 and 3 is 2. Because you sum numbers which results 4, and then divided by 2 (the amount of numbers involved in the average).
find the simple interest on £120,000.00 for 5 months at 12% per annum
Answer:
£6,000
Step-by-step explanation:
Use the simple interest formula:
I = Prt
I = (Principal Value)*(Annual Interest Rate)*(Time in Years)
I = (120000)(0.12)(5/12)
I = 6000
Therefore, the simple interest is £6,000

Any translation can be replaced by two reflections.
Any translation can be replaced by two rotations.
Any rotation can be replaced by a reflection.
Any reflection can be replaced by a rotation followed by a
translation.
Answer:
truetruefalsefalseStep-by-step explanation:
One characteristic of a reflection that is useful for answering this question is that it always reverses the clockwise/counterclockwise orientation of a figure. Rotation and translation have no effect on that orientation.
__
1. translation by reflection
Reflection across two parallel lines has the net effect of translating a figure twice the distance between the parallel lines. So, one way to effect a translation using two lines of reflection is to draw one of them through the perpendicular bisector of a point and its translated image. Then the other line would be drawn parallel to the first through the image point.
True: translation can be replaced by two reflections
__
2. translation by rotation
A single point can be moved from one set of coordinates to another by rotating around any point on the perpendicular bisector of the original and its image. To "undo" the change in direction of other points in the image, the image can be rotated an equal angle in the reverse direction about the point that is in its proper place.
That is, if we rotate figure ABC an amount of X° about a point on the perpendicular bisector of AA', so that A ends up at A', then the translation can be finished by rotating that figure by -X° about point A'.
The simplest case is an initial rotation of 180° about the midpoint of AA', followed by another rotation of 180° about A'.
True: translation can be replaced by two rotations
__
3. rotation by reflection
As discussed above, reflection changes orientation and rotation does not.
However, a rotation can be replaced by two reflections. The rotation angle is equal to twice the angle between the lines of reflection. The point where the lines of reflection meet is the center of rotation.
False: rotation can be replaced by reflection
__
4. reflection by rotation and translation
As discussed above, reflection changes orientation, but rotation and translation do not.
False: reflection can be replaced by rotation and translation

Ted is saving for a toy. He has no money now, but
he figures that if he saves $D per week for the next
4 weeks he will have $1 more than he needs for the
toy. Write an expression for the cost of the toy Ted
wants to buy in terms of D. Explain.
Answer:
4D - 1
Step-by-step explanation:
So, if Ted saves $D for 4 weeks, then this amount will be equal to 4D because multiplication is simply repeated addition. We can imagine this situation as D+D+D+D, for the 4 weeks he is saving. We can simplify this to 4D in the expression.
Next, the question tells us that this will be 1 dollar more than needed. So, if we want to find the cost, we need to subtract that dollar.
Thus, the final expression is 4D - 1 because this represents 1 dollar less than the money he saves for 4 weeks.
Periodical cicada species emerge in large
numbers from their larval stage at different
yearly intervals. What is the GCF of the years?
The GCF of numbers is the greatest common factors between the numbers
The GCF of the years is 1
How to determine the GCFThe intervals are given as: 13 years and 17 years
Factor both intervals (i.e. 13 and 17)
13 = 1 * 13
17 = 1 * 17
The common factor between both products is 1
So, we have:
GCF = 1
Hence, the GCF of the years is 1

Answer:
a) h = 6 2/17
b) k = 3 8/17
Step-by-step explanation:
We can make a list of corresponding sides:
AB (17 cm) and DE (13 cm)
BC (15 cm) and EC (8+k cm)
CA (8 cm) and CD (h cm)
Because the triangles are similar, we know corresponding sides are proportional.
a)CD/CA = DE/AB
h/8 = 13/17
h = 8(13/17) = 6 2/17
__
b)EC/BC = DE/AB
(8+k)/15 = 13/17
8 +k = 15(13/17)
k = 11 8/17 -8 = 3 8/17
