Answer:
C) 80 milliamperes
Step-by-step explanation:
The amount of current flowing through a circuit is directly proportional to the amount of voltage applied across the circuit. The relation between current(I) and voltage(V) can be expressed as:
Here, 
is the proportionality constant. It is given that, when voltage is 2 volts, 40 milliamperes(
amperes) current flow through the circuit. Using these values we can find the value of proportionality constant. i.e.
Using this value, we can establish the relation between I and V as:
Now, we need to calculate value current (I) if voltage is equal to 4 volts. Substituting V = 4 in above equation, we get:
Thus, the value of current will be 80 milliamperes
we have that
A+B=B+A -------> is the same
so
B+A= (1-5) (-3+3) (4-5) (-5-2)
(2-4) (5-2) (-4+4) (4-5)
<h2>B+A= -4 0 -1 -7</h2><h2> -2 3 0 -1</h2>
Answer:
38inch2
Step-by-step explanation:
3inch*2inch+8inch*4inch
=6inch2+32inch2
=38inch2
The function h is defined, for all real numbers , answer is as follows -
h(1) = - 2
h(2) = 3
h(4) = 3.
function, an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable
We have been given that
h(x) = 1/4(x) - 1 if x < -2
h(x) = -(x + 1)² + 2 if -2 ≤ x < 2
h(x) = 3 if x ≥ 2
Find h (1), h (2), and h (4)
For h (1) -
Value of h(1) for h(x) = -(x + 1)² + 2 as if -2 ≤ x < 2
So put x = 1
h(x) = -(x + 1)² + 2
h(1) = -(1 + 1)² + 2
h(1) = -4 + 2
h(1) = - 2
For h (2) -
Value of h(2) for h(x) = 3 as if x ≥ 2
h(x) = 3
h(2) = 3
For h (4) -
Value of h(4) for h(x) = 3 as if x ≥ 2
h(x) = 3
h(4) = 3
Hence , the value for given functions - h(1) = - 2 , h(2) = 3 and h(4) = 3.
