The measurement of AB is 16.23.
Solution:
Given ACB is a right angled triangle.
AC = 10, ∠C = 90° and ∠A = 52°.
cos θ ≈ 0.616
Here AC is the base and AB is Hypotenuse.
To find the length of AB:
Do cross multiplication, we get
AB = 16.23
Hence the measurement of AB is 16.23.
The correct answer is A) 37.4%.
The probability that the first volunteer is a man would be 32/52, since there are 32 men out of 52 people. The probability that the second volunteer would also be a man would be 31/51, since there is 1 fewer man and 1 fewer person total to choose from.
32/51(31/51) = 992/2652 = 0.374 = 37.4%.
We have the following equation:
If we graph this equation we realize that in fact this is an ellipse with
major axis matching the y-axis. So we can recognize these characteristics:
1. Center of the ellipse: The midpoint C<span> of the line segment joining the foci is called the </span>center<span> of the ellipse. So in this exercise this point is as follows:
</span>
2. Length of major axis:
The line through the foci is called the major axis<span>, so in the figure if you go from -5, at the y-coordinate, and walk through this major axis to the coordinate 1, the distance you run is the length of the major axis, that is:</span>
3. Length of minor axis:
The line perpendicular to the foci through the center is called the minor axis. So in the figure if you go from -2, at the x-coordinate, and walk through this minor axis to the coordinate 2, the distance you run is the length of the minor axis, that is:
4. Foci:Let's find c as follows:
Then the foci are:
Answer:
Friday night.
Less expensive.
Step-by-step explanation:
Cost of 1 ticket on Friday = 48/3 = $16.
Cost on Saturday = 36 / 2 = $18.
Now 96 / 6 = $16 so the brother and his friends will have to go to the Friday concert. From the above costs we see that they did buy the less expensive ticket.
