Answer:
A. Sin 2x
Step-by-step explanation:
This is a trig function and has the shape of sine or cosine. Since it intersects at (0,0), it is likely a sine graph. A normal sine graph starts at (0,0), crests up at 1, and crosses back down at the x-axis at (3.14, 0). However, this graph starts at (0,0) and crosses back again at half that value. This graph has been horizontally compressed by multiplication of a number greater than 1. So this graph is Sin 2x.
Answer:
4:1
Step-by-step explanation:
When converting between ratios and fractions, the denominator of the fraction is always the sum of all the numbers in a ratio. So you can eliminate the first (4:9) and last (4:5) answers because 4+9 and 4+5 do not add up to 5.
That leaves you with the middle two answers. Honestly, it could also be 1:4 but since the question talks about Josh receiving the money, the ratio would be 4 parts for him and 1 for Lucy, so 4:1 is probably the correct option
Assuming there is no specific percentages in the grade book, you would need a grade of 95 to get your whole grade to 90. You find this out by working backwards starting with 90 to find average. You take 90 times 2 which equals 180 and you subtract 85 from that to get 95! Brainliest?
