Answer:
about 2.1
Step-by-step explanation:
The slope of the secant line is given by the slope formula:
m = (y2 -y1)/(x2 -x1)
m = (121/100 -1)/(11/10 -1) = (21/100)/(1/10) = 2.1
The slope of the tangent is about 2.1.
_____
Additional comment
We can refine our estimate by choosing a secant line between the points (9/10, 81/100) and (11/10, 121/100). That is, points either side of x=1.
That slope is ...
(121/100 -81/100)/(11/10 -9/10) = (40/100)/(2/10) = 2.0
We expect the slope of the tangent at x=1 to be exactly 2.0.

Answers
9514 1404 393
Answer:
335 ft
Step-by-step explanation:
The relationship between distances and the angle is ...
Tan = Opposite/Adjacent
tan(28°) = (lighthouse height)/(distance to ship)
distance to ship = (178 ft)/tan(28°) ≈ 334.77 ft
The ship is about 335 ft from the base of the lighthouse.

Christina loses 2 1/2 pounds every month for a year. How much weight did she lose that year? There are 12 months in a year. Simplify (or reduce) your answer, if necessary.
Answers
Answer:
30 pounds
Step-by-step explanation:
So for this problem you do 2 1/2 * 12, or 5/2 * 12. You get 60/2 = 30.
Answer:
30 pounds
Step-by-step explanation:
We start by converting 2 1/2 pounds into its decimal form: 2.5 pounds.
Now we consider that there are 12months per year, therefore in one year she will lose:
2.5 * 12 = 30 pounds

Answers
Answer:
2/9
Step-by-step explanation:
each city has a probability of 1/9
one city 'or' another means to add their probabilities: 1/9 + 1/9 = 2/9
The probability of Cleveland or Dallas getting picked is [tex]\frac{2}{9}[/tex].
What is probability?'Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.'
According to the given problem,
Total number of city names = 9
Favorable events = 2 [ Cleveland, Dallas]
Probability = [tex]\frac{Favorable events}{Total number of events}[/tex]
Probability of Cleveland getting picked = [tex]\frac{1}{9}[/tex]
Probability of Dallas getting picked = [tex]\frac{1}{9}[/tex]
Probability of Cleveland OR Dallas getting picked = [tex]\frac{1}{9}+\frac{1}{9}[/tex]
= [tex]\frac{2}{9}[/tex]
Hence, we can conclude, probability of Cleveland or Dallas getting picked is [tex]\frac{2}{9}[/tex].

Daniel and Hector both throw shot put for their school's track and field team.
They each threw 5 times and recorded their distances to the nearest foot.
Daniel's Shot Put Throws (feet)
27, 30, 34, 35, 34
Hector's Shot Put Throws (feet)
38, 24, 38, 40, 35
Who has the greater mean, and by how much?
А Daniel by 3 feet
B Hector by 3 feet
С Daniel by 6 feet
D Hector by 6 feet
Answers
Answer:
Option B : Hector by 3 feet is the correct answer.
Step-by-step explanation:
Given that:
Mean of Daniel = [tex]\frac{Sum\ of\ quantities}{Number\ of\ quantities}[/tex]
Mean of Daniel = [tex]\frac{27+30+34+35+34}{5} = \frac{160}{5}[/tex]
Mean of Daniel = 32 feet
Mean of Hector = [tex]\frac{38+24+38+40+35}{5} = \frac{175}{5}[/tex]
Mean of Hector = 35 feet
Therefore,
Hector has a greater mean
Difference = Hector's Mean - Daniel's Mean
Difference = 35 - 32
Difference = 3 feet
Hence,
Option B : Hector by 3 feet is the correct answer.
50, 20, 8, ...
Find the 8th term.
Answers
Answer:
0.08192
Step-by-step explanation:
Given 50, 20, 8, ...
The sequence is geometric in nature
The nth term of the geometric sequence is exoressed as;
Tn = ar^{n-1}
a is the first term = 50
r is the common ratio = 20/50 = 8/20 = 2/5
n is the number of term = 8 (since we need the 8th term)
Substitute
T8 = 50(2/5)^{8-1}
T8 = 50(2/5)^7
T8 = 50(128/78,125)
T8 = 0.08192
Hence the 8th term is 0.08192

In Omak the sales tax is 8.4%. What is the total cost including tax Aakel spent on a $48 purchase?
Answers
Answer:
$52.03
Step-by-step explanation:
1. Approach
To solve this problem, first one needs to calculate the sales tax, then one must add that to the amount spent on the purchase. To calculate sales tax, one must convert the percent to decimal form, this can be done by dividing the percent by 100. Then one will multiply the decimal by the amount spent.
2. Find the tax
As states above; to calculate sales tax, one must convert the percent to decimal form, this can be done by dividing the percent by 100. Then one will multiply the decimal by the amount spent.
a. convert percent to decimal
8.4 / 100 = 0.084
b. multiply the decimal by the amount spent
48 * 0.084 = 4.032
The amount spent on sales tax is, $4.032
3. Find the total amount spent
Now all one has to do is add the amount spent in tax by the amount spent on the purchase.
48 + 4.032 = 52.032
Since money is only spent rounded to the second decimal point, one has to round the number;
52.03

k = y/x
For the given non-zero point (1/4, 3/8), the value of k is found to be ...
