Answer:
15
Step-by-step explanation:
its the same as the other angle on there
Answer:
Step-by-step explanation:
f(x) = x²
f(4) = 4² = 16
f(1) = 1² = 1
f(-3) = -3² = 9
f(t) = t²
Always wise to us the ^ symbol to represent powers to avoid confusion
4^2 = 4² = 16
-3^2 = 9
t^2
if you are on a PC, the square symbol (²) can be typed by holding down the "alt" key while pressing and releasing "2","5","3" on the keypad, then release "alt". Unfortunately this does not work if you only have the row of numbers on the keyBoard to work with.
Answer:
y=2x+1.
Step-by-step explanation:
You first need to find the slope of the line already graphed. -2 to 1 would be three units to the right, and -2 to 4 would be six units up. You would use the equation (y2-y1)/(x2-x1), where x1 and y1 would be the x and y values of the first coordinate of the graphed line, and x2 and y2 would be the second coordinate. This would be 6/3, which can be simplified to 2/1, which can be simplified to 2, which would mean the slope of the given line would be 2, as well as the parallel line. Now, you could use a pretty complicated equation to find the y-intercept of the line you need to graph, but I would recommend using the slope to find it. Since the given point is (3, 7), you would need to go to the left, meaning you would reverse the slope until you reach the y-axis, so you would use -2 as the slope. 3*-2=-6, and 7-6=1, so the y-intercept would be 1. The answer would be y=2x+1. Hope this helps.
Given:
and 
.
To find:
The quadrant.
Solution:
We know that,
In I quadrant, all trigonometric ratios are positive.
In II quadrant, only 
are positive and others are negative.
In III quadrant, only 
are positive and others are negative.
In IV quadrant, only 
are positive and others are negative.
We have,
and .
Here, 
is positive and 
is negative. So, 
lies in the III quadrant.
Therefore, the correct option is C, i.e., III.
