Answers:
Center = (4, 7)
Radius = 7
===========================================================
Explanation:
The general template of any circle is
(x-h)^2 + (y-k)^2 = r^2
This general circle has these properties:
Based on the equation your teacher gave you, we see that
- h = 4
- k = 7
- r = 7, since 7^2 = 7*7 = 49
Therefore, this circle has center = (4,7) and radius = 7
Side note: The center's y coordinate and radius aren't always the same value.
Answer:
$341.96
Step-by-step explanation:
Assuming Kerry was not paid at an overtime rate for extra hours (despite his union affiliation), his gross pay is ...
(46 h)×($9.60/h) = $441.60
His percentage deductions add to 17.65%, so will have a dollar amount of ...
0.1765×$441.60 = $77.94
The dollar amount deductions total $21.70 in addition to his percentage deductions, so Kerry's net pay is ...
$441.60 -77.94 -21.70 = $341.96
To convert an angle from degrees to radians, multiply by π/180°.
Your angle is
(-280°)*(π/180°) = -14π/9
The appropriate choice is ...
B) (-14π/9)
Step 1:
Here we have -3 in subtraction on the left side, so when we take it to the right we apply opposite operation of subtraction that is addition.
Step 2:
Next we have 4 in multiplication on left side, so dividing right side by 4,
Step 3:
taking log on both sides
Step 4:
Dividing right side by 2,
x= ln (3.75) /2 = 0.66088
Answer : x = 0.66088..
