Answer:
The amount of calories Lucie will burn by jumping for 1 minute is 8 calories
Step-by-step explanation:
The given data values are;
Minutes Calories Burned
40 320
80 640
120 960
160 1280
The value of calories burnt and the number of minutes of jump robe are seen to be directly proportional, such that we have;
40 minutes of jump rope will yield 320 calories burnt
Therefore we have;
1 minute of jump rope will yield 320/40 = 8 calories burnt
The amount of calories Lucie will burn by jumping for 1 minute = 8 calories.

Answer:
z=-9 - 5.4

Step-by-step explanation:
please mark me brainliest
5^2 + 3^2 (equals to 34) ; That's the wrong expression
It should look like this : (5+3)^2 (which equals to 64)
First, we are going to find the common ratio of our geometric sequence using the formula:
. For our sequence, we can infer that
and
. So lets replace those values in our formula:
Now that we have the common ratio, lets find the explicit formula of our sequence. To do that we are going to use the formula:
. We know that
; we also know for our previous calculation that
. So lets replace those values in our formula:
Finally, to find the 9th therm in our sequence, we just need to replace
with 9 in our explicit formula:
We can conclude that the 9th term in our geometric sequence is <span>
