Answer:
The correct answer is A) 76 degrees
Step-by-step explanation:
In order to solve the equation for mT, we can use trigonometric functions. Since we are given the side adjacent to the angle and the hypotenuse, we'll use cos.
Cos(α) = ADJ/HYP
Cos(α) = 4/17
Cos-1(α) = .235
α = 76 degrees
22. The degree for each interior angle would be 125°.
An angle can be up to 180°(straight line) for a shape such as a polygon.
23. The answer would be a scalene triangle. Not all the angles are the same degree.
21 I'm not sure:(
Answer:
17 times
Step-by-step explanation:
Let "x" be the number of times today's investment is more than the investment 10 years ago
Investment 10 years ago = 1.25*10^3 = 1,250
Investment today = 2.125*10^4 = 21,250
So, we can form the equation as shown below:
1250*x = 21,250
x = 21,250/1,250
x = 17
Therefore, today's investment is 17 times greater than the investment 10 years ago
Answer:
A.
Step-by-step explanation:
We are given the two points (2,7) and (4,-1). In order to determine the linear equation, we need to find the slope and the y-intercept. First, find the slope <em>m.</em> Let (2,7) be x1 and y1, and let (4,-1) be x2 and y2:
Thus, the slope is -4.
Now, to find the y-intercept, we can use the point-slope form. Recall that the point slope form is:
Where (x1, y1) is a coordinate pair and m is the slope.
Use either of the two coordinate pair. I'm going to use (2,7). Substitute them for x1 and y1, respectively:
This is also slope-intercept form. The answer is A.
Step-by-step explanation:
yes its ans is (3,3) fast you have see in x axis then y axis .so according to this we write 3 which lies in x- axis and then another 3 which lies in y-axis.
