What are Similar Figures?Similar figures are known to be figures that are said to be of the same shape. They are known to have the same exact size, or one may be bigger than the other.
Note that when two shapes are similar, it is said that their corresponding angles are often same. The angles are also known to be the same because the shape is still of the same shape and as such one can be able to tell from the way or order of the similarity based on the way that the angles match up and also in the scenario above.

Suppose that the average bill for the drive through of 24 customers at Burger Palace is $14.30. It is known that the population standard deviation is σ=2.30. Estimate the true mean bill for a customer at Burger Palace with 95% confidence.
Answers
The standard deviation is a measure of a collection of values' variance or dispersion. The true mean bill for a customer at Burger Palace with 95% confidence is $13.38.
What is a standard deviation?The standard deviation is a measure of a collection of values' variance or dispersion. A low standard deviation implies that the values are close to the set's mean, whereas a high standard deviation shows that the values are spread out over a larger range.
Given that the Sample mean ([tex]\overline x[/tex]) is $14.30, the Sample size(n) is 24 customers, the Standard deviation(σ) is 2.30, while for a 95% confidence interval the Z-score is 1.960. Therefore, the true mean can be written as,
[tex]Z = \dfrac{\overline x- \mu}{\frac{\sigma}{\sqrt n}}\\\\\\1.960 = \dfrac{14.30-\mu}{\frac{2.30}{\sqrt{24}}}\\\\\\1.960 = \dfrac{14.3-\mu}{0.47}[/tex]
μ = 13.3788 ≈ 13.38
Hence, the true mean bill for a customer at Burger Palace with 95% confidence is $13.38.

Answer:
First we need to determine what cos is asking for. Using Soh Cah Toa we can tell that we are using adjacent (a) and hypotenuse (h). The leg that is adjacent to Q is equal to 10 while the hypotenuse is equal to 21.
[tex]cos(Q)=\frac{adjacent}{hypotenuse}[/tex]
[tex]cos(Q) = \frac{10}{21}[/tex]
After getting to this part, we have to take the inverse of cos in order to cancel the cos on the left and leave Q by itself.
[tex]cos^{-1}(cos(Q))=cos^{-1}(\frac{10}{21})[/tex]
[tex]Q = 61.56\ degrees[/tex]
In the end we are left with that our angle Q is equal to 61.56 degrees.

8.1. If x is the distance from P to the flagpole and h is the height of the flagpole, then
tan(53°) = h/x
tan(28°) = h/(x + 20)
Solve for the first equation for h in terms of x :
h = x tan(53°)
Substitute this into the second equation and solve for x :
tan(28°) = x tan(53°) / (x + 20)
(x + 20) tan(28°) = x tan(53°)
x tan(28°) + 20 tan(28°) = x tan(53°)
x (tan(28°) - tan(53°)) = -20 tan(28°)
x = 20 tan(28°) / (tan(53°) - tan(28°))
x ≈ 13.4 m
8.2. By the law of cosines,
BD² = 7² + 11² - 2 • 7 • 11 cos(110°)
⇒ BD = √(170 - 154 cos(110°))
⇒ BD ≈ 14.9 cm
and
BC² = BD² + 16² - 2 • BD • 16 cos(40°)
⇒ BC = √(426 - 154 cos(110°) - 32 cos(40°) √(170 - 154 cos(110°)))
⇒ BC ≈ 10.6 cm
Now use Heron's formula. If S is the semiperimeter of ∆ABD and S' is the semiperimeter of ∆BCD, i.e.
S = (AB + BD + AD)/2 ≈ 16.5 cm
S' = (BC + CD + BD)/2 ≈ 20.7 cm
then
area ∆ABD = √(S (S - AB) (S - BD) (S - AD)) ≈ 36.2 cm²
and
area ∆BCD = √(S' (S' - BC) (S' - CD) (S' - BD)) ≈ 76.7 cm²
so that the total area of ABCD is approximately 112.9 cm².
Since the beginning of the month a local reservoir has been losing water at a constant rate. On the 10th of the month, the reservoir held 300million gallons of water and on the 18th it held only 262 million gallons. A. Write an equation that will give the amount of water in the reservoir at any time B. Hov, much water was in the reservoir on the 14th of the month? C. When will the reservoir get empty?
Answers
Total amount in the reservoir = amount of water in the 10th month - (rate of decline x number of months from the 10th month)
Rate of decline = (300 262) / (18 - 10) = 4.75
y = 300 million = 4.75x
Where x is the time of the month.
What will be the quantity of water in the reservoir on the 14th of the month?Total amount in the reservoir = amount of water in the 10th month - (rate of decline x number of months from the 10th month)
300 million - (4.75 x 4) = 281 million
When will the reservoir be empty?
0 = 300 - (4.75x)
x = 300 / 4.75
x = 63.16 days

Step-by-step explanation:
The transformation that reflects f(x) across the y-axis is replacement of x with -x.

For f(x) = x +1, replacement of x with -x will perform the desired transformation:
g(x) = f(-x) = (-x) +1
g(x) = -x +1
Reflection across y axis rule
(x,y)=(-x,y)so x turns negative
hence f(x) turns f(-x)new one is

DiameterSemicirclePoint of TangencyInternal Common TangentMajor ArcRadiusCenter of a CircleExternal Common TangentSecantChordMinor Arc===========================================================
Explanations:
The diameter is a segment that goes through the center of a circle. Both endpoints are on the circle's edge. The diameter is twice the radius.Arc EGF forms a half circle, better known as a semicircle. The measure of angle EBF is 180 degrees, which is half of a full 360 rotation.Point G is a point of tangency. It's the point of tangency of the two circles, and also the point of tangency for any particular circle and the tangent HJ.Line HJ is the internal common tangent. It is tangent to both circles. We consider it internal since it crosses over the line segment that would connect the centers A and B. Notice that the external tangent KF does not cross the segment that would connect A and B.Arc CDK is a major arc of circle A. By definition, a major arc is anything larger than a semicircle. In other words, if its measure is over 180 degrees, then we have a major arc. A minor arc is anything smaller than 180.Segment BF is a radius of circle B. It is half the diameter EF. If you know the radius, then double it to get the diameter. The radius is from the center of the circle to any point on the circle's edge.Point A is the center of circle A. We label the circle names based on their center.As mentioned earlier, line KF is a external common tangent to the circles. It is tangent to both circles, and it is external in the sense it doesn't cross over line segment AB (you'll have to draw in line segment AB to see that it doesn't cross).Line CD is a secant line. A secant line crosses a circle at exactly two different points. In contrast, a tangent line only touches a circle at exactly one point.Segment GK is a chord. It's basically the segment version of a secant line. A chord is any segment where the endpoints are on the circle's edge. The diameter is a special type of chord.Arc CK is a minor arc. We start at C and travel the shortest distance along the circle to arrive at point K. This is less than a semicircle, so it's why we go with minor arc instead of major. The measure is less than 180 degrees.Solve for r.
