Answer:
A. g(x) = -2x^5 - 1.
Step-by-step explanation:
Reflection over the x axis results in the function -x^5.
Vertical stretch of 2 gives -2x^5
Finally a shift down of 1 unit gives -2x^5 - 1
The function results after applying the sequence of transformations to
f(x) = x⁵ is,
⇒ g(x) = -2x⁵ - 1.
What is mean by Function?A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
Now,
After Reflection over the x axis results in the function is,
g (x) = - x⁵
And, After Vertical stretch of 2 gives,
g (x) = -2x⁵
Then, Finally a shift down of 1 unit gives,
g (x) = -2x⁵ - 1
Thus, The function results after applying the sequence of transformations to f(x) = x⁵ is,
⇒ g(x) = -2x⁵ - 1.

Answer:
[tex]BC=9\sqrt{3}\approx15.59\text{ units}[/tex]
Step-by-step explanation:
Since Segment BOA is a diameter:
[tex]m\angle ACB=90[/tex]
Arc Ac and Arc CB are in a ratio of two to four. Since Segment BOA is a diameter, Arc ACB measures 180°. Letting the unknown value be x, we can write that:
[tex]2x+4x=180[/tex]
Hence:
[tex]x=30[/tex]
Thus, Arc CB = 120°. By the Inscribed Angle Theorem:
[tex]\displaystyle m\angle A=\frac{1}{2}\left(\stackrel{\frown}{CB}\right)=\frac{1}{2}\left(120)=60[/tex]
Therefore, ΔABC is a 30-60-90 triangle. Its sides are in the ratios shown in the image below.
Since AC is opposite from the 30° triangle, let AC = a.
We are given that AC = 9. Hence, a = 9.
BC is opposite from the 60° angle and it is given by a√3. Therefore:

Eduardo purchased a car for $18,500 with 6.5% sales tax, a freight charge of $450, a registration fee of $155, and an ownership fee of $45. Eduardo made a down payment
of $2.500, the total amount financed would be:
$18.056.50
$17.852.50
$17.398.75
$18.235.75
None of these choices are correct
Answer: $17,852.50
Step-by-step explanation:
First find the total cost of the car including the various charges:
Sales tax = 18,500 * 6.5%
= $1,202.50
Total cost = Purchase price + sales tax + Freight charge + Registration fee + Ownership fee
= 18,500 + 1,202.50 + 450 + 155 + 45
= $20,352.50
Subtract the down payment to find out the amount that will be financed:
= 20,352.5 - 2,500
= $17,852.50

The difference between accuracy and precision
Answer:
Accuracy is the degree of closeness between a measurement and the measurement's true value. Precision is the degree to which repeated measurements under the same conditions are unchanged.
Definition With Example
Accuracy refers to the closeness of a measured value to a standard or known value. ... Precision refers to the closeness of two or more measurements to each other. Using the example above, if you weigh a given substance five times, and get 3.2 kg each time, then your measurement is very precise.

Layla is cutting bows out of ribbon which will be used to wrap gifts. If Layla needs 21/22of a foot of ribbon to make a bow, and she has 21 feet of ribbon, then how many bows can Layla make?
Answer:
21 bows
Step-by-step explanation:
Since 21/22 is just 1 short of a whole 1, we can first round it up to a whole 1, and subtract it later. 21 divided by 1 is just 21, and now is the time to subtract the part in which we rounded out. 1/22 times 21 is 21/22, so Layla can't make an entire bow with it.
What is the conversion for m/s to km/h ?
Answer:
3.6km/hr
Step-by-step explanation:
What is the conversion for m/s to km/h ?
According to the conversion
1m = 0.001km
1s = 1/3600 hr
m/s to km/hr = 0.001/(1/3600)
= 0.001×3600
= 3.6
Hence the conversion is 3.6km/hr
2. Suppose the measures of the interior angles of a convex octagon are eight
numbers, each separated by a value of 1 degree from its neighbors. Find
the measure of the second smallest angle.
118°
131°
132.5°
142°
None of these answers are correct.
=====================================================
Explanation:
The interior angles are consecutive numbers such as 1,2,3,... or 7,8,9... and so on. The gap between any two adjacent neighbors is 1.
For any polygon with n sides, the interior angles add up to 180(n-2)
We have n = 8 sides so the interior angles sum to 180(n-2) = 180(8-2) = 1080 degrees.
Any octagon has its interior angles add up to 1080 degrees.
-----------------------------
Let x be the smallest angle. The next angle up is x+1. After that is x+2 and so on until we reach x+7 as the 8th angle.
Add up those 8 angles, set the sum equal to 1080 and solve for x
x+(x+1)+(x+2)+(x+3)+(x+4)+(x+5)+(x+6)+(x+7) = 1080
8x+28 = 1080
8x = 1080-28
8x = 1052
x = 1052/8
x = 131.5
This is the smallest angle. The next angle up or the second smallest angle is x+1 = 131.5+1 = 132.5 degrees (choice C)

Answer:
It takes _8_ s for an object to fall 1000 feet. In 10 s, an object will fall _1600_ feet.
Step-by-step explanation:
A. Determination of the time it takes for the object to 1000 ft.
Distance (d) = 1000 ft
Time (t) =?
t = √(d/16)
t = √(1000/16)
t = 8 s
B. Determination of how much feet an object will fall in 10 s.
Time (t) = 10 s
Distance (d) =?
t = √(d/16)
10 = √(d/16)
Take the square of both side
10² = d/16
100 = d/16
Cross multiply
d = 100 × 16
d = 1600 ft
SUMMARY
It takes _8_ s for an object to fall 1000 feet. In 10 s, an object will fall _1600_ feet.
