Answer:
Step-by-step explanation:
The given notation is not clear enough, but I will asume that the question is: "Wich is the vector lenght of the vector in a 3 dimensional euclidean space"
Vector lenght of a vector is given by the next formula:
║║=
In this case we have a=2, b=3 and c=1. We should substitute these values in the formula given before to obtain:
║║=
Wich is the answer to the problem.
Answer: x=-2/5
Step-by-step explanation:
1. Expand: 3x+6=4-2x
2. Subtract 4 from both sides: 3x+6-4=-2x
3. Simplify 3x+6-4 to 3x+2: 3x+2=-2x
4. Subtract 3x from both sides: 2=-2x-3x
5. Simplify -2x-3x to -5x: 2=-5x
6. Divide both sides by -5: -2/5=x
7. Switch sides: x=-2/5
Hope this helped!
Answer:
$2.50
Step-by-step explanation:
Given the daily pay formula :
P(b)=5/2b+45
P(b) = employee’s total daily pay
b = number of bushels of peaches picked
Hence from the fórmula ; rate which employees are paid per bushel. Of peach picked is the gradient of the equation :
According to the intercept slope formula:
y = mx + c ; where m = slope or gradient
From the equation :
P(b)=5/2b+45
The slope or gradient is 5/2 ; hence, employees are paid $5/2 per bushel of peaches picked.
$5/2 = $2.50
