Answer:
8.4 cm
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you of the relationship between the sides of a right triangle and the trig functions of an angle. Here, we are given the side adjacent to the angle, and we want to find the side opposite. This suggests the Tangent relationship could be useful:
Tan = Opposite/Adjacent
tan(35°) = x/(12 cm)
(12 cm)·tan(35°) = x ≈ 8.4 cm . . . . . . multiply by 12 cm
Answer:
1/7
Step-by-step explanation:
Lets start with the probability of flipping tails, 1/2.
Then the probability of the day starting with the letter s, 2/7.
Calculate the final probability by multiplying the two together.
You can simplify 2/14 down to 1/7
Answer:
17
Just substitution!
Step-by-step explanation:
f(-2) = 17×(3-2)
Answer:
Step-by-step explanation:
The slope of a line can be seen as:
Rise over run is the change in the y values over the change in x values. For example, in this graph, you would start on one of the points given. From there, you would move up first. After moving up a certain number of spaces, you would move to the side until you reach the other point.
In the graph, you would move up until you are in line with one of the other points. Starting at (-4,5), move up one space, then to the left 4 spaces to reach the point (0,6). Using the spaces moved in the rise over run:
Therefore, the slope is .
This is true for any two points on the line.
:Done
*When you move up, the number will be positive . If you move down, the number will be negative . If you move left, the number will be positive . If you move right, the number will be negative . Keep this in mind. It is very important.
**Always <em>move along the y-axis first</em>, then move along the x-axis. If you do it the other way, the slope will be wrong.
Hello from MrBillDoesMath!
Answer:
22.6
Discussion:
From the attachment, the square has sides of length "x", and the Pythagorean theorem applies. Hence
x^2 + x^2 = 8^2 =>
2 x^2 = 8^2 => divide both sides by 4
x^2 = 8^2/2 => 8^2 = 64, 8^2/2 = 32
x^2 = 32 =>
x = sqrt(32) = => as 32 = 16 * 2
x = sqrt(16) * sqrt(2) =>
x = 4 sqrt(2)
The perimeter is 4*x
= 4*(4 sqrt(2) )
= 16 * sqrt(2) => as sqrt(2) is approx 1.41
= 22.6
Thank you,
