Let x be the number of hours the student swims per day.
We have been that a student swims one hour every day, so in 2 months the student will swim 60 hours.
We are also told that the student swims 800 meters each day. This means that slope of the graph that represents the total meters swam during the time of her training program will be 800.
So in 60 days the student will swim
.
We can see from our attached graph that at x equals 60 our y is approximately 48.
Since y-axis represents the number of meters in thousands, so 48 stands for 48,000.
Therefore, attached graph is the right choice.
Hi! So for this word problem, you would just decide 117 devided by 2. You would get 58.5. After that, you will have to round. If it is 5 or higher, you round up. So the FINAL answer would be 59. Hope this helped!
Answer:
c. 9 det A
Step-by-step explanation:
Given the following data;
Since A is a square matrix of order 2, we know that n = 2
K = 3
For any scalar k;
∣kA∣ = k^{n} ∣A∣
<em>Substituting into the equation;</em>
∣-3A∣ = -3²∣A∣
Simplifying, we have;
∣-3A∣ = 9∣A∣
= 9 detA
<em>Therefore, det (-3A) = 9 detA</em>
Volume of a rectangular prism = l × w × h.
In this case,
V = 270 cubic feet
l = 15 feet
w = 4 ft
h = ?
Plug our values into the volume formula.
270 cubic feet = 15 feet × 4 feet × h.
Simplify the right side
270 = 60 × h.
Divide each side by 60.
4.5 = h
The height is 4.5 feet.
