From this, we conclude that; Current equals Voltage divided by Resistance (I=V/R), Resistance equals Voltage divided by Current (R=V/I), and Voltage equals Current times Resistance (V=IR).To calculate voltage, V: put your finger over V, this leaves I R, so the equation is V = I × R.
To calculate current, I: put your finger over I, this leaves V over R, so the equation is I = V/R
ANSWER
The vertex is (-2,1)
EXPLANATION
We want to find the vertex of
We complete the square to obtain,
The first three terms forms a perfect square trinomial.
The vertex form is
This equation is in the form;
where (h,k)=(-2,1) is the vertex.
The comments are that they both are multidigits numbers
Answer:
The base is 8 ft and the height is 6 ft.
Step-by-step explanation:
If the height of the triangle is x feet its base = 2x - 4 feet.
So the area of the triangle
= 1/2 * base * height
= 1/2 * (2x - 4) * x = 24
(x - 2) * x = 24
x^2 - 2x - 24 = 0
(x - 6)(x + 4) = 0
x = 6, -4 As x is the height it must be 6 feet.
The base = 2x - 4 = 2(6) - 4 = 8 feet.
Using tangent, you would get an answer of around 54.949548389096. Tangent would equal: tan(20 degrees = 20/x wand upon solving x equals the answer above.
