Answer:
for this graph the answer is D
Example:
If I give u a ratio of the number of teachers to students is 2:1 would mean that for every 2 teachers there is 1 student.
In question 10(a) the ratio of grey to black is 3:1 which means that the percentage would be 33%
In 10 (B) the ratio would be 6:4
Answer:
g(x) = - sqrt(x+8) reflected about the x axis and shifted 8 units to the left
h(x) = 2 sqrt(x) +1 is stretched by 2 in the y direction and shifted up 1 in the y direction
Step-by-step explanation:
y = f(x + C) C > 0 moves it left
So we moved it 8 units to the left
y = −f(x) Reflects it about x-axis
g(x) = - sqrt(x+8) reflected about the x axis and shifted 8 units to the left
y = f(x) + C C > 0 moves it up
so we moved it up 1 units
y = Cf(x) C > 1 stretches it in the y-direction
and stretched it by 2 in the y direction
h(x) = 2 sqrt(x) +1 is stretched by 2 in the y direction and shifted up 1 in the y direction
Answer:
488 meters above sea level.
Step-by-step explanation:
Since the difference between that point and the tallest point is 1,232 you need to subtract 1,232 - 12 = 1,220 to get how far Mt ka'ala is from sea level. Since the ranger station is 2/5 up the mountain you can do 1,220/5 = 244. This is 1/5 of the way up the mountain. Then you do 244 x 2 = 488. That is 2/5 up the mountain. Final answer: The ranger station is 488 meters above sea level.
