Believe it or not, this is the second version of Q is very similar to the first, even though it doesn't really look like it. We can represent the second version as a * (1 + r)^t
See the similarity between this and the first version? Thus, we can represent what is given in the problem as:
Q = a * b^t = a * (1 + r)^t
Thus, b = 1 + r. Since b = 0.8, we can find r.
0.8 = 1 + r
r = -0.2, or r = -20%.
Answer:
6/9,5/8
Step-by-step explanation:
Those were just examples, they can be literally any number between 5/9 and 3/4.
Answer:
2. 8:45am to 5:15pm
Step-by-step explanation:
Looking at the table of John's times, he arrived at 8:42am and left at 5:14pm. If you are rounding to the nearest quarter hour, or 15 minutes, you time would need to be at the hour, 15 minutes after, 30 minutes after or 45 minutes after. Given those options, the closest times would be 8:45am and 5:15pm.
Answer:
Step-by-step explanation:
Domain= All real numbers. To get this answer i just plug the x-values into the quadratic formula to get the y-output.
Maximum area=1323/8
Range= y<= 1323/8
Answer:
9) 6.3 units
11) n=6√2 and m=12,
10) m=6√3, n=6
12) 330.6 ft
Step-by-step explanation:
1) The Pythagoras Theorem says that, the square of the hypotenuse is the sum of the squares of the two shorter legs.
Let the missing side, which is the hypotenuse be x.
Then
The missing side is 6.3 units to the nearest tenth.
2) This is an isosceles right triangle.
This implies that, the two legs are equal.
The hypotenuse can be found using Pythagoras Theorem.
3) The side lengths of 30°-60°-90° are in the ratio, 2x,x√3,x
From the diagram, the hypotenuse is 12, therefore the other two legs are
and
4) The height of the monument is 115 feet, the hypotenuse is 350.
By Pythagoras Theorem,
