Answer:
m = 5
a = -3
b = -15
Step-by-step explanation:
(m - 2) = 3 for x^2
(2a + 3) = - (m - 2) = (2 - m) for x^1
(b + 6) = (2a - 3) for x^0
Answer:
y =
+ 5
Step-by-step explanation:
So here we have to put it in y = mx + b form;
7x + 4y = 20
Subtract 7x from both sides;
4y = -7x + 20
Divide both sides by 4;
y =
+ 5
Answer:
Horizontal component: 40.95
Vertical component: 28.67
Step-by-step explanation:
To find the horizontal and the vertical component of this vector, you need:
The formula for calculate the horizontal component:

Where
is the magnitude
The formula for calculate the vertical component:

Where
is the magnitude
Given the angle 35 degrees and the magnitude,you can substitute values into the formulas.
Therefore, you get that the horizontal component and the vertical component of this vector are:


I just answered a so let's start with b :
______________________________
b. The equivalent resistance of series
resistances is equal to their sum
Thus :
equivalent resistance = 480 + 360
equivalent resistance = 840

c.
I = V ÷ R
I = 120 ÷ 840
I = 0.1428 A
_______________________________
d. 0.1428 A
_______________________________
e. 480 ===》 120 - ( 480 × 0.1428 ) =
120 - 68.544 =
51.456
360 ===》 120 - ( 360 × 0.1428 ) =
120 - 51.408 =
68.592
