It’s gonna be all real numbers (-infinity, infinity) because it goes through all the points. And because there’s no restrictions
Answer:
2x + 5x - 4 + 1
basic addition of terms together
( 2 + 5 ) x + ( -4 + 1 )
7x - 3
Since lateral surface of an object is the area of all the sides of the object, except the area of its base and top.
It is:
7 * 3 = 21
21 * 2 = 42
12 * 3 = 36
36 * 2 = 42
42 + 42 = 84 in2
and there goes your answer.
A: 84 in2.
Answer:
Step-by-step explanation:
One approach to this type of word problem is to list the information you are given:
Step 1:
$19.95 = basic monthly charge
$0.05 = per minute charge$23.74 = total monthly billx = the number of minutes used
Step 2:
Next, put these things into an algebraic expression.
Total monthly bill = basic monthly charge + (per minute charge) * (number of minutes used)
Step 3:
Now, plug in the numbers for your first step and solve.
$23.74 = $19.95 + $0.05x
-19.95 -19.95
$3.79 = $0.05x
divide each side by 0.05 to find x
You could also rewrite the problem at step 2. It just depends if you like working with numbers (algebra, variables, etc.) or thinking about the problem in words (more a verbal style of learning).
Number of minutes used = cost for minutes / per minute charge
Number of minutes used = (Total monthly charge - basic monthly charge) / per minute charge
Answer:
Option 2.
Step-by-step explanation:
It is given that
a = <6,-9,3>
We need to compare the maginitude of vertor a and vector 4a.
If a vector is defined as v = <x,y,z>, then its magnitude is defined as
Using the above formula we get
The vector 4a is
The magnitude of 4a is a factor of 4 greater than the magnitude of a.
Therefore, the correct option is 2.
