Answer:
-2/3
Step-by-step explanation:
To find the slope, pick two points on the line, and use the slope formula
( 0,50) and (30,30)
m = ( y2-y1)/(x2-x1)
= (30-50)/(30-0)
= -20/30
= -2/3
Answer:
3rd jump
Step-by-step explanation:
The distance jumped is given in the table attached. to get the jump that do not round up to 4.7 meters, we round each of the jump to one decimal place and then select the jump that does not round up to 4.7 meters.
Therefore rounding off gives:
1st jump: 4.746 meters = 4.7 meters to one decimal place
2nd jump: 4.680 meters = 4.7 meters to one decimal place
3rd jump: 4.647 meters = 4.6 meters to one decimal place (does not round to 4.7 meters)
4th jump = 4.733 meters = 4.7 meters to one decimal place
Answer:
2. "two thirds of the fourth power of <em>r</em>"
4. n + 14
6. 7 +11n
8. (2/5)n^2

7. 28
8. 1/5
Step-by-step explanation:
2. "two thirds of the fourth power of <em>r</em>"

4. "sum" means the listed items are added. You can use any convenient variable to represent "a number." I often use <em>n</em> for <em>n</em><em>umber</em>.
n + 14
__
6. "7 more than" means 7 is added to whatever follows. "11 times a number" means the number is multiplied by 11.
7 + 11n
__
8. "of" means "times". The square of a number is that number to the power of 2.
(2/5)n^2

7 & 8 (evaluation). Your calculator can do this. (If not, get one that can.) Note that parentheses are needed around numerators and denominators and anything else that must be treated as a single value.
