Answer:
Step-by-step explanation:
Given the function
We can rewrite it as
Now we can apply the power rule
Now we can rewrite it
Now we can plug in x=-8
You would have to use the formula gallons/ hours, so when you plug the numbers in you get to 1,375 gallons per hour.
hope this helps!! :)
2x+10=y
6+10=16
Choice C (3,16) is correct.
Answer:
1) Yes, it is a right angle triangle
2)Yes, it is a right angle triangle
3) No, they are not similar.
Step-by-step explanation:
Dimension of triangle A = 48, 55 & 73
Dimension of triangle B = 36, 77 & 85
For any of the triangles to be a right angled one, then;
c = √(a² + b²)
Where a,b & c are side dimensions of a triangle.
Thus;
Triangle A: c = √(48² + 55²)
c = √5329
c = 73
This tallies with what we are given and so it is a right angled triangle.
Triangle B: c = √(36² + 77²)
c = √(7225)
c = 85
Similar to the third side dimension of 85, thus it is true.
For Triangle A & B to be similar, the ratio of the 3 corresponding sides must be in a whole number ratio.
Thus, we have;
48/36 = 1.5
55/77 = 5/7
73/85 = 73/85
Since the ratios are not similar, then we can say that the triangles are not similar.
8th Graders: [clarinet] 4/40
4/40 can be simplified: divide by 4 (1/10)
Percentage = x100
1/10 x 100 = 10%
Answer: 8th Grade clarinet percentage = 10%
