Find the first three terms of the sequence with nth term 3n-2​
kykrilka [37]

Answer:

To find out the first three terms of 3n - 2 substitute 1 ,2 and 3 into the equation.

so the three terms a

 3(1)-2=1

3(2)-2=6-2=4

3(3)-2=9-2=7

As you can see the sequence goes up in 1,4 and 7.To find out the 10th term you also substitute 10 into the equation so 3(9)-2=18-2=16

so 16 is the tenth term

Hope this helped!

a jogger ran 4 miles, decreased her speed by 1 mile per hour, and then ran another 5 miles. If her total jogging time was 2 1/20
LekaFEV [45]
Let the speed of the joker initially be x mi/hr
after reduction, the new speed will be: (x-1) mi/hr
but
time=(distance)/(speed)
hence :
Total time taken will be:
4/x+5/(x+1)=41/20
solving for x we get:
x=21.585 mi/hr
thus the initial speed was 21.585 mi/hr after reduction the new speed was 20.585 mi/hr

A glider flies 13 miles north from the airport and then 24 miles diagonally southeast. Approximately how far west does the glide
NISA [10]

Answer:

20.2 miles

Step-by-step explanation:

This can be described by the three sides of a right angled triangle. Let the distance of the glider to the airport be represented by x, applying the Pythagoras theorem:

/hyp/^{2} = /adj1/^{2} + /adj2/^{2}

/24/^{2} = /x/^{2} + /13/^{2}

576 = x^{2} + 169

x^{2} = 576 - 169

   = 407

x = \sqrt{407}

  = 20.1742

x = 20.2 miles

The glider has to fly 20.2 miles to return to the airport.

One hundred times the quantity five plus three
Maru [420]
Five-5

three-3

"the quantity five plus three" (5 + 3) 

"one hundred times the quantity ..." means  100 (5 + 3)   

now just solve 100(5+3) 

solve the parentheses first (5+3) = 8

Now you are left with 100(8) or 100*8

when you solve your answer is 800
