For this, you have to understand the ratios of a 30,60,90 triangle. The ratio(in order) is x, x(sqrt 3), 2x (following the 30,60,90 pattern y'know). Well, we know the length of the hypotenuse, 4.2, so let's use ratios to figure the other sides out. The ratio of AC is x and the ratio of AB is 2x, so 2x/2=x=2.1. One side down. BC has a ratio of x(sqrt 3). We already know x so we can substitute it in. We get 2.1(sqrt 3). To calculate the area, use the formula 1/2(bh). Inputting the values in, we get 1/2(2.1*(2.1(sqrt 3)). This can be calculated to around 3.82. To calculate the perimeter, take the sum of the sides. By adding the sides together, we get about 9.98. Hope you can now understand how to do these kinds of questions.
75) The domain is all values of x and range is all values of y. Given this, domain is -1 <u><</u> x <u><</u> 6. Range is 1 <u><</u> y <u><</u> 5. It is not a function because it does not pass the vertical line test. (Shown in image. Blue line is the vertical line and green line is the line shown based on the graph.)
76) The ordered pairs are:
- (0, 1)
- (1, 2)
- (2, 3)
- (-1, 4)
- (6, 5)
Answer:
The answer is 1.79 × 10-3
309 = 310
27 = 30
310 × 30 = 9300
9300 is your answer!
HOPE THIS HELPED :)
Answer:
There are a few solutions because there are some fractions and decimals between 8 and 10.
