Answer:
distance travelled by sprinter = 100 m
Time taken = 11.21sec
∵speed = distance/time taken
= 100/9.83
= 10.17 m/s
Now we know, 1 km/h = 1000/3600 m/s
so, 1 m/s = 3600/1000 km/h = 18/5 km/h
∴ 10.17 m/s = 10.17 × 18/5 = 10.17 × 18/5 = 36.612 km/h
Hence, average speed = 36.612 km/h
Step-by-step explanation:
Answer:
distance travelled by sprinter = 100 m
Time taken = 11.21sec

Which equation represents a line that passes through (4, 1/3) and has a slope of 3/4.
Answer:
y = 3/4x - 2 2/3
Step-by-step explanation:
Are there choices?

If f(x) = 3-8(x-2), what is f(-9)
Answer:
f(- 9) = 91
Step-by-step explanation:
To evaluate f(- 9) substitute x = - 9 into f(x), that is
f(- 9) = 3 - 8(- 9 - 2) = 3 - 8(- 11) = 3 + 88 = 91

Answer:
x = 23.125°
Step-by-step explanation:
∠ACF = ∠GCB (vertically opposite angles)
3x + 5x - 5 = 180° (angles on a straight line are supplementary)
8x = 185°
x = 23.125°
This is a question on angles. If you wish to venture further into it/understand this topic better, you may want to follow my Instagram account (learntionary), where I post some of my own notes on certain topics and also some tips that may be useful to you :)

Answer:
5b +3r -12k +5-13k +2Step-by-step explanation:
It looks like you want to simplify the sums.
1. (3r -4) -(-5b -3) = 3r -4 +5b +3 = 5b +3r +(-4+3)
= 5b +3r -1

2. (-4k -1) -(-6k -6) = -4k -1 +6k +6 = (-4+6)k +(-1+6)
= 2k +5
__
3. (-6k +7) -(7k +5) = -6k +7 -7k -5 = (-6-7)k +(7-5)
= -13k +2

0.01
Step-by-step explanation:
Determine any data values are missing from the table assuming that the data represents a linear function.
Answer:
Missing x:0
Missing y:1
Hence, option b is correct.
Step-by-step explanation:
Given the table
x y
-9 3
-6 2
-3 missing
missing 0
As we know that the linear function has a constant common difference between the x values and y values.
From the table, it is clear that the x values have the same common difference, and the consecutive x values are separated by -3.
i.e. -9-(-6)=-3
-6-(-3)=-3
So the missing x value will be:
-3-(x)=-3
-3-(0)=-3
Therefore, the missing x value wil be: 0
From the table, it is clear that the x values have the same common difference, and the consecutive x values are separated by 1.
i.e.
3-2=1
2-y=1
y=1
Therefore, the missing y-value will be 1.
Therefore,
Missing x:0
Missing y:1
Hence, option b is correct.
