Where's the Lie?
Here are three statements that Tiana wrote about this
exponential
One of the statements is a lie. Which is it?
A. For very large values of x, the exponential has very large
values of y.
OB. The y-intercept of the exponential is (0,1).
C. The point (-2,4) is on the exponential.
Explain how you know it's a lie.
Answers
Answer:
A.
Step-by-step explanation:
As the x value is increasing the y is decreasing because the graph shows exponential decay.
The graph of a simple exponential function always pass through (0,1)
The statement that is a lie is (a) For very large values of x, the exponential has very large values of y.
From the graph, we have the following highlights
The graph passes through point (0,1); this means that the y-intercept is (0,1).The graph passes through (-2,4)The above highlights mean that options (b) and (c) are true, while option (a) is a lie
Option (a) is a lie because, as the value of x increases, the value of y increases.

In the circle below, diameter CD is perpendicular to chord AB as shown. Radii OB and OA are drawn.
(a) How could we prove that OEB is congruent to OEA? Explain.
(b) What does your answer tell you must be true about segments AE and BE ? Why?
(c) If the diameter of circle O is 20 and CE 4, then determine the length of AB . Show how you arrived at your answer.
Answers
Answer:
The length of AB is 16 units.Step-by-step explanation:
(a)We know that [tex]\angle OEB = 90\°[/tex], by given, so it's a right angle, by definition.
[tex]\angle OEA[/tex] and [tex]\angle OEB[/tex] are adjacent angles on a straight angles. That means they are sumplementary angles by definition.
[tex]\angle OEA + \angle OEB = 180\°\\ \angle OEA = 180\° -90\°\\\angle OEA = 90\°[/tex]
Therefore, [tex]\angle OEA = \angle OEB[/tex].
(b)Sides AE and BE are congruent, because the congruence between those right angles, and the congruence between the other corresponding sides justify the congruence between sides AE and BE.
Notice that the hypothenuses of each right triangle are congruent, because they are also radius of the circle, which means they are congruent by definition.
Additionally, side OE is a common leg for both right triangles.
Therefore, sides AE and BE are congruent.
(c)We know that [tex]d=20[/tex] and [tex]CE=4[/tex], that means the radius is
[tex]r=\frac{d}{2}=\frac{20}{2}=10[/tex]
Notice that the chord AB is formed by AE and BE by sum of segments.
We know the hypothenuses are equal to 10 units of length, because they are radius.
Additionally,
[tex]OC=OE+EC[/tex], by sum of segments.
[tex]10=OE+4\\OE=10-4\\OE=6[/tex]
Which means the common leg is 6 units long.
Now, we use the Pythagorean's theorem to find the missing leg
[tex]OB^{2}=EB^{2}+OE^{2}\\ 10^{2}=EB^{2}+6^{2}\\100-36=EB^{2}\\EB=\sqrt{64}\\ EB=8[/tex]
But, [tex]AB=AE+EB[/tex], by sum of segments.
[tex]AB=8+8=16[/tex], because [tex]AE=EB[/tex] we said before.
Therefore, the length of AB is 16 units.
22. There are 31 girls and
25 boys in the marching band. When
the band marches, they are in 7 rows.
How many people are in each row?
Answers
Answer:
8
Step-by-step explanation:
To solve this problem, you need to divide the total number of people the by the amount of rows you have to see how many people can fit in each row.
With 31 girls and 25 boys, you have a total of 56 people. Divide 56 by 7 to get 8.
You will have 8 people in each row.
Answer:
8 people.
Step-by-step explanation:
31 + 5 = 36. 36 + 20 = 56.
56 divided by the number of rows which is 7 in this case = 8.
There will be 8 people per row. Consisting of males and females.

For a class project, a teacher cuts out 15 congruent circles from a single sheet of paper that measures 6 inches by 10 inches. How much paper is wasted?
Answers
Answer:
60 – 15π square inches
Step-by-step explanation:
Assuming a diameter of 2 inches for each circle, then because the height of the sheet is 6 inches and the length is 10 inches, 5 columns of 3 circles each, are formed (see picture attached).
The area of each circle is: (π*D^2)/4 = (π*2^2)/4 = π square inches
The area of the 15 circles is: 15π square inches
The area of the sheet is = 6*10 = 60 square inches
The wasted paper is equal to the difference between the area of the sheet and the area of all circles, that is, 60 – 15π square inches
Answer:
60 – 15π square inches

The expected value of a ticket of the local fire company given the price and the expected values is $-9.50.
What is the expected value?
The expected value is the sum of the prizes added to the cost.
Expected value = value of the prizes - cost
(300 + 150 + 50 + 0) - (10 x 1000)

An icicle is in the shape of an inverted cone with a diameter of 9 mm and a height of 27 mm. In cubic millimeters, how much frozen water is in the icicle? Use 3.14 for . Round your answer to the nearest hundredth.
Answers
Answer:
volume ≈ 572.27 mm³
Step-by-step explanation:
The icicle is in the shape of an inverted cone with a diameter of 9 mm and a height of 27 mm. To find how much in cubic millimetres the frozen water is in the icicle can be calculated below.
In other words the question want us to find the volume of the cylinder. The volume of the cone can be represented as follows:
volume of a cylinder = 1/3πr²h
where
r = radius
h = height
diameter = 9 mm
height = 27 mm
r = diameter/2 = 9/2 = 4.5
volume = πr²h
volume = 1/3 × 3.14 × 4.5² × 27
volume = 1/3 × 3.14 × 20.25 × 27
volume = 1/3 × 63.585 × 27
volume = 1716.795/3
volume = 572.265 mm³
volume ≈ 572.27 mm³
Answer:
572.27 mm³
Step-by-step explanation:
A circle has a central angle that measures 23º and the arc length is 12pi. Find the measure of the radius in radians. Round answers to nearest hundredth.
Answers
Answer:
The radius of the circle is 93.91
Step-by-step explanation:
In order to calculate the radius of this circle we can apply the formula to find the arc length. This formula is shown below:
length = [(angle)*pi*radius]/180
Since we want to find the radius we can isolate that variable, as shown:
(angle)*pi*radius = length*180
radius = (length*180)/(angle*pi)
radius = (12*pi*180)/(23*pi) = (12*180)/23
radius = 93.91
