X = 0.89
x = -0.89

So, for the area of a circle, there should be a line in the middle. Correct?
Well, that line is the diameter. Then cut that in half, so if the diameter is 6, the radius is 3.
Then multiply the the radius by the radius, so 3x3 once you get that, multiply the answer by pi. Pi= 3.14, so if you do 3x3x3.14 you should get 28.26. Hope this helps.
Answer:
the room is -1m by 14m
Step-by-step explanation:
what you do to find it is first find x.
the perimeter is 26, and one side is 15 meters longer than the other(twice).
So the equation is:
x + (x + 15) + x + (x + 15) = 26
2x + 2(x + 15) = 26
2x + 2x + 30 = 26
4x + 30 = 26
26 - 4x = 30
26 - 26 - 4x = 30 - 26
-4x = 4
-4x/-4 = 4/-4
x = -1
Now we have two sides of the room. Now we want the 15m longer ones...
-1 + 15 = 14
so the dimensions are -1 by 14, or -1x14
Hope this helps. if this is the best answer, mark Brainliest.
If not, hope it helps anyway.
The plotting point should definitely start at 2 because the 2 is with the x and that is the slope(starting point).
Answer:
Hope it helps!
Step-by-step explanation:
The general form of a cubic function is y = ax3 + bx + cx + d where a , b, c and d are real numbers and a is not zero. We can graph cubic functions by plotting points.
A cubic function is any function of the form y = ax^3 + bx^2 + cx + d, where a, b, c, and d are constants, and a is not equal to zero, or a polynomial functions with the highest exponent equal to 3. These types of functions are extremely prevalent in applications involving volume.
