Step-by-step explanation:
Area of triangle is B X H X0.5
Answer:
JK= 8x-4
Step-by-step explanation:
This is achieved by adding JM And MK because M is the midpoint of JK.
Answer:
4
Step-by-step explanation:
Let the number be x.
(11+41)/x = 13
52/x = 13
13x = 52
x = 52/13
x = 4
Answer:
x = -3/2
Step-by-step explanation:
7⁰ = 1 (anything to the power of 0 equals 1)
7²ˣ ⁺ ³ = 7⁰
Since the bases are the same, you 'forget' about the bases and then you solve for x.
2x + 3 = 0
2x = -3
x = -3/2
Answer:
y = 0.8425 or y = -0.8425
Step-by-step explanation:
All points in the Cartesian coordinate system have an x and y coordinate, defined by two perpendicular measurements.
If the point is on the unit circle, then the radius of the circle is defined to be 1 unit, and the corresponding right triangle follows the Pythagorean Theorem.

For a unit circle:

Substituting the known value for x, and simplifying...


Subtracting 0.29019769 from both sides to begin to isolate "y"...


Applying the square root property...


So, (to 4 decimal places), the y coordinate could be either 0.8425 or -0.8425.
With only the given information, either result is a valid answer.
