A sequence has its first term equal to 4, and each term of the sequence is obtained by adding 2 to the previous term. If f(n) re

presents the nth term of the sequence, which of the following recursive functions best defines this sequence? (1 point)
a
f(1) = 2 and f(n) = f(n − 1) + 4; n > 1

b
f(1) = 4 and f(n) = f(n − 1) + 2n; n > 1

c
f(1) = 2 and f(n) = f(n − 1) + 4n; n > 1

d
f(1) = 4 and f(n) = f(n − 1) + 2; n > 1

Answer:It would be f(n)= f(n-1) +4 this is because f(n-1) means the previous term and you would add your 4 every time you gain.

Molly walked 3.45 miles on a hike. Her sister walked 1.23 miles. Her brother walked 0.85 miles. Round each distance to the neare
Marina CMI [18]
3.45 rounded to the nearest tenth is 3.5.
1.23 rounded to the nearest tenth is 1.2.
0.85 rounded to the nearest tenth is 0.9.
To find how much further Molly walked than her brother and sister combined, you'd have to combine the amount of miles Molly's brother and sister walked:
1.2 + 0.9 = 2.1
Next, you would have to subtract Molly's amount of miles walked with the combination of her brother and sister's miles walked:
3.5 - 2.1 = 1.4
So, Molly walked 1.4 more miles on her hike than her brother and sister had walked combined.

Olegator [25]

Answer:

Approximately 50% of the vehicle speeds were less than 42 mph

Step-by-step explanation:

The normal distribution is symmetric:

That is, 50% of the measures are below the mean and 50% of the measures are above the mean.

In this problem, we have that:

Mean = 42 mph

So

Approximately 50% of the vehicle speeds were less than 42 mph

Suppose someone tells you that she has a triangle with sides having lengths 2.2, 4.5, and 6.7. Is this a right triangle?
laila [671]
You can apply the Pythagorean theorem:
a^2 + b^2 = c^2
c is the longest side of the triangle
2.2^2 + 4.2^2 = 6.7^2
4.84 + 17.64 = 44.89
22.48 =/= 44.89
That is not a right triangle
