Jordan swam 4 laps. Each lap is 100 meters. Jordan’s average speed for the first 3/4 of his swim was 40 meters per minute, and f

Leya [2.2K]

Answer/step-by-step explanation:

The 300/40 comes from the fact that ¾ of a 400 meter swim is 300 meters, and if you want to know how long he took to do that, you need to divide by the speed, 40 meters per minute (meters divided by meters per minute = minutes). Likewise with the 100/35—that’s the last 100 meters he swam, at the slightly slower speed.

Just to bring it all the way home, average speed is total distance divided by total time. that the total distance is 400 meters. You know the total time is 300/40 + 100/35. Average speed, then, is:

Average Speed: $= \frac{400}{\frac{300}{40} +\frac{100}{35} }$

Round: 39 meters per minute

Sequence: 49, 36, 25, 16, 8, 4, 1 * Is this a arithmetic or geometric sequence? and if it is arithmetic find the common differen

timurjin [86]

Answer:

Step-by-step explanation:

The sequence is nor properly written. This is correct sequence

49, 36, 25, 16, 9, 4, 1...

Merely looking at the sequence, we can see that it doesn't form an arithmetic sequence nor does it form a geometric sequence.

The values of the sequence are all perfect squares.

Rewriting the sequence;

7², 6², 5², 4², 3², 2², 1²...

Now we can see that the base values for an arithmetic sequence as shown:

7, 6, 5, 4, 3, 2, 1...

We find the common difference of this sequence as shown

d = T2-T1 = T3-T2 = T4-T3

Given T1 = 7, T2 = 6, T3 = 5, T4 = 4

Substitute

d = 6-7 = 5-6 = 4-5 = -1

d = -1

Get the nth term using the sequence

Tn = a+(n-1)d

a is the first term

d is the common difference

n is number of terms

Tn = 7+(n-1)(-1)

Tn = 7+(-n+1)

Tn = 7+1-n

Tn = 8-n

Since their power are constant i.e squared, hence we will square the ntj term as well to get the nth term of the original sequence as;

Tn = (8-n)²

To conclude, we can say that the sequence is neither arithmetic nor geometric sequence since the terms of the sequence are prefect squares.

What is the equation of the line described below written in slope-intercept form? The line passing through point (0,0) and paral

artcher [175]

Answer:

$y = - \frac{ 3}{2} x$

Step-by-step explanation:

slope-intercept form

y= mx +c, where m is the slope and c is the y-intercept.

Let's rewrite the given equation into the slope-intercept form so we can find out its gradient.

3x +2y -6= 0

2y= -3x +6

Dividing by 2 throughout:

$y = - \frac{3}{2} x + 3$

Thus gradient of given line= $- \frac{3}{2}$

Parallel lines have the same gradient.

Thus gradient of line= $- \frac{3}{2}$

Subst. m= $- \frac{3}{2}$ into the equation:

$y = - \frac{3}{2}x + c$

To find c, substitute a pair of coordinates.

When x=0, y=0,

$0 = - \frac{3}{2} (0) + c \\ c = 0$

Thus, the equation of the line is $y = - \frac{3}{2} x$ .
