Henry located 2 1/4 and 2.1 on a number line. He wrote the following related story:
Rzqust [24]

Answer:

Jerry ran a farther distance and not Henry.

Step-by-step explanation:

We are given the following information in the question:

Jerry rain 2\frac{1}{2} miles and Henry ran 2.1 miles.

Henry claimed that he ran a farther distance.

This is a wrong claim because when we compare:

2\frac{1}{2} and 2.1

2\displaystyle\frac{1}{2} = \displaystyle\frac{5}{2} = 2 + 0.5 = 2.5\\\\2.5 > 2.1

Hence, Jerry ran a farther distance and not Henry.

Henry may have made some mistake in plotting   2\frac{1}{2} and 2.1 on the number line.

A sequence can be generated by using fn = 2f(n-1)+1, where f1 = 4 and n is a whole number greater than 1. What are the first fou
hoa [83]

Answer:

<em>{9,19,39,79}</em>

Step-by-step explanation:

<u>Recursive Sequences</u>

The recursive sequence can be identified because each term is given as a function of one or more of the previous terms. Being n an integer greater than 1, then:

f(n) = 2f(n-1)+1

f(1) = 4

To find the first four terms of the sequence, we set n to the values {2,3,4,5}

  • For n=2

f(2) = 2f(1)+1

Since f(1)=4:

f(2) = 2*4+1

f(2) = 9

  • For n=3

f(3) = 2f(2)+1

Since f(2)=9:

f(3) = 2*9+1

f(3) = 19

  • For n=4

f(4) = 2f(3)+1

Since f(3)=19:

f(4) = 2*19+1

f(4) = 39

  • For n=5

f(5) = 2f(4)+1

Since f(4)=39:

f(5) = 2*39+1

f(5) = 79

The cost of 1 purse and 1 watch is £27.
EastWind [94]
1 purse and 1 watch is 27€
2 purse and 1 watch is 41€

So we can see the watch is constant means 1 watch is every time but purse is increase by 1 in the next expression

So 41-27 = 14€ is one purse
because the watch is every time one, so the next value increase is by purse

1purse and 1watch = 27
We know,
1 purse is 14€
So 27-14=13€ is one watch

We can check by
1 purse is 14 so two purse is 14*2=28
28+13=41
Which is same as they said in second expression

Hope it help you!¡

Answer you get brainliest and we can be buddies. (i am very loney)
kolbaska11 [484]

Answer:

10017

Step-by-step explanation:

10^(4)-\sqrt(121)+3^(3)+4^(0)

So, 3^3= 27

4^0=1

10^4=10,000

-square 121= -11

So now you got:

10,000-11+27+1

=10017
