A runner is participating in a 10.3 mile race. If the runner stopped at a water station that is twice as far from the starting l

Rudik [331]

We have the representation of this problem in the figure below. As we have a 10.3 mile race, then the equation is fulfilled as:

$d = 10.3mi = d_{1}+ d_{2}$

We know that there is a water station that is twice as far from the starting line as from the finish line, then:

 $d_{2}=2d_{1}$

So:

$d_{1} +2d_{1}=10.3$
∴ $d_{1}=3.43mi$

and $d_{2}=2(3.43)=6.86mi$

Finally, the distance of the runner from the finish line is:

$6.86mi$

The equation that could be used to determine the total number of people is given as y is equal to 3^x.

<h3>What is an exponential function?</h3>

It is defined as the function that rapidly increases and the value of the exponential function is always a positive. It denotes with exponent y = a^x

where a is a constant and a>1

Let y be the total number of people that will be tagged.

And let x be a number of the round.

We are assuming the first is when Kyla posted a photo challenge on social media and tagged 3 friends.

So from the problem the equation becomes:

$\rm y = 3^x$

At first round x = 1, y =3

At second round x = 2, y = 9

At third round x = 3, y = 27

Thus, the equation that could be used to determine the total number of people is given as y is equal to 3^x.

Solve for x and y 3x + 2y = 16 7x + y = 19

alukav5142 [94]

Answer:

(x, y) = (2, 5)

Step-by-step explanation:

Double the second equation and subtract the first:

2(7x +y) -(3x +2y) = 2(19) -(16)

11x = 22

x = 2

In the second equation, ...

7(2) +y = 19

y = 19 -14 = 5

The solution is (x, y) = (2, 5).

Answer:

B) f(1)=7, f(n+1)= f(n)-3; for n >= 1

Step-by-step explanation:

The first term of the sequence is 7 and the next (4) is found by adding -3 to that: 4 = 7-3. This is described in answer choice B.
