Step-by-step explanation:
it takes her 2 minuetes and 50 seconds to do 1 lap if you multiply 2.5x17=
42 munites and 5 secondesto do 17 laps
Answer:
It would take 42.5 min

4/10 = 2.5(unit rate for every lap it takes 2.5 min)
17 x 2.5 = 42.5
John saved $50,000. and wants to put the money into an Index Annuity that pays an average of 8.4% per year, compounded semi-annually. How long will it take him to reach his goal of $1,000,000?
Answer:
Divide 50,000 by 8.4...get that number and add it to the 50,000, divide again by 8.4 and add back, repeat until you reach 1,000,000... happy adding

Step-by-step explanation:
2^{51} mod 22 in words, two to the power of fifty-one mod twenty-two
Since 2⁵ = 32, and
2⁵ ≡ 32 ≡ 10 (mod 22),
we have
2⁵¹ ≡ 2 • 2⁵⁰ ≡ 2 • (2⁵)¹⁰ ≡ 2 • 10¹⁰ (mod 22)
Now consider 10¹⁰ (mod 22):
10 = 2 • 5
10¹⁰ ≡ 2¹⁰ • 5¹⁰ ≡ (2⁵)² • 5¹⁰ ≡ 10² • 5¹⁰ ≡ 2² • 5¹² (mod 22)
so that
2⁵¹ ≡ 2³ • 5¹² (mod 22)
Now consider 5¹² (mod 22):
5 and 22 are coprime, and ɸ(22) = 10 (where ɸ(n) is the Euler totient function). By Euler's theorem,
5¹² ≡ 5² • 5¹⁰ ≡ 5² • 1 ≡ 25 ≡ 3 (mod 22)
and so
2⁵¹ ≡ 2³ • 3 ≡ 24 ≡ 2 (mod 22)
Another, more tedious method: Start with smaller powers of 2 and look for a pattern.
2 ≡ 2 (mod 22)
2² ≡ 4 (mod 22)
2³ ≡ 8 (mod 22)
2⁴ ≡ 16 (mod 22)
2⁵ ≡ 32 ≡ 10 (mod 22)
2⁶ ≡ 2 • 32 ≡ 2 • 10 ≡ 20 (mod 22)
2⁷ ≡ 2 • 20 ≡ 40 ≡ 18 (mod 22)
2⁸ ≡ 2 • 18 ≡ 36 ≡ 14 (mod 22)
2⁹ ≡ 2 • 14 ≡ 28 ≡ 6 (mod 22)
2¹⁰ ≡ 2 • 6 ≡ 12 (mod 22)
2¹¹ ≡ 2 • 12 ≡ 24 ≡ 2 (mod 22)
2¹² ≡ 2 • 2 ≡ 4 (mod 22)
and so on, with a cyclic pattern of length 10. That is, [tex]2^{10k+1}\equiv2\pmod{22}[/tex] for any integer k ≥ 0. So 2⁵¹ ≡ 2 (mod 22).

The time it takes to fly from Los Angeles to New York varies inversely as the speed of the plane. If the trip takes 5 hours at 950 km/h, how long would it take at 850 km/h?
I know the answer is 5.588 but why like what are the steps to solve it?
Answer:
Step-by-step explanation:
find distance traveled: [tex]\frac{950 km}{1 hr}*{5 hrs}[/tex] = 4750 kmtotal distance / new speed: [tex]\frac{4750 km}{850 km/hr} = 5.5882 hrs[/tex]Which is a different way to express 2(w + 3)?
Answer: 2w+6
Step-by-step explanation: Here you distribute. Simply multiply 2 and w which would get you 2w and 2 by 3 which would get you 6.

Where is the function increasing?
9514 1404 393
Answer:
A) 1 < x < ∞
Step-by-step explanation:
"Increasing" means the graph goes up to the right. This graph is increasing for values of x greater than 1. (x=1 is a minimum. The graph is decreasing toward the minimum on the left of that value, and increasing from the minimum on the right of that value.)
1 < x < ∞

So the method we will use is quadratic formula it's will tell us from the start whether this equation have a real solution no solution or one solution only calculating its discriminant
b²-4ac=3²-4(3)(5)
9-60=-51
If the discriminant is < 0 means the equation have no solution

A farmer plants 22,680 wheat plants in 126 rows. Each row contains the same number of plants. How many wheat plants are in each row?
Help me please
Answer:
180 plants per row
Step-by-step explanation:
This is a division problem.
When he places 22,680 plants in 126 rows, he is dividing the 22,6980 plants by 126 rows.
22,680/126 = 180
Answer: 180 plants per row
A study found that on average there were 566,000 tweets per hour.
Using this data, how many tweets are there per minute?
A
33, 960,000
B
13,584,000
С
18,866.6
D
9,433. 3
Work Shown:
566,000 tweets = 1 hour
566,000 tweets = 60 minutes
566,000/60 tweets = 60/60 minutes .... divide both sides by 60
9,433.3 tweets = 1 minute
There were roughly 9,433.3 tweets per minute.
In the function, f(x) = 6x2 – 4 , what is the value of f(-2)?
Answer:
f(-2) = 14
Step-by-step explanation:
f(-2) = 6(-2) 2 - 4
f(-2) = -12 + 2 - 4
f(-2) = -10 - 4
f(-2) = -14
-16 + (unknown) = -6
