Answer:
x<3. Hope this helps!
Step-by-step explanation:
Its a bit tricky to explain without a diagram bot if we take a point (a, b) on the coordinate plane as the center of the circle and another point (x,y) on the circumference then the distance between (a,b) and (x,y) is the radius of the circle.
Now create a triangle by drawing a line horizontally from (a,b) to the circumference and another line prerpendicular to this line from the point (x,y) to make a right angled triangl.e
Applying the pythagoras theorem to this triangle gives
(x - a)^2 + (y - b)^2 = r^2 which is the standard form of equation of a circle.
Answer:
A = 126 in²
Step-by-step explanation:
The formulate for a trapezoid Area is
A = (a+b)/2 *h
So, simple: 12+16 (2x 2) inches on each side = 16 Top
Bottom is 12 inches, and the height is 9 inches. Plug into the Formula
(12+16)/2 *9 = 126 in²
Answer:
(–∞, –3)
Step-by-step explanation:
The function is a quadratic function of order 2 and positive coefficient.
This is in the form of the function , but it is displaced 3 units to the left of the x axis and two units up in the y axis. type of functions are decreasing from -∞ to its vertex and then they are increasing from the vertex to infinity.
Observe in the attached graph that this function has its vertex in the point (-3, 2) and is decreasing from -∞ to x = -3. Then it is increasing until ∞. Therefore the correct option is:
(-∞, -3)
Answer:
x=5.8
Step-by-step explanation:
I kinda guessed on this due to the fact you didn't provide a photo. I used the pythagorean equation to solve this.
Start by identifying you a, b, and c sides.
