Answer:
f(3) = 7
Step-by-step explanation:
f (x)=x + 4
Let x=3
f (3)=3 + 4
f(3) = 7
Answer
Find out the which coordinate pair identifies the center of the circle represented by 4x² + 4y² − 16x − 24y + 36 = 0.
To prove
The general equation of the circle is
(x - h)² + (y - k)² = r²
Where h,k are the centre and r is the radius.
4x² + 4y² − 16x − 24y + 36 = 0
Divided both side by 4.
x² + y² − 4x − 6y + 9= 0
Add and subtract 4 and 9
x² + y² − 4x − 6y + 4 -4 +9 - 9 +9= 0
x² + y² − 4x − 6y + 4 -4 + 9 - 9 +9= 0
x² + 4 - 2× 2 × x + y² + 9 - 2 × 3 × y = 9 + 4 - 9
using the formula ( a + b )² = a² + b² +2ab
(x - 2)² + (y - 3)² = 2²
Compare this with the general equation of circle.
Thus
h = 2 , k = 3
Option A is correct .
Answer:
Using the given information in the problem, the final evaluated answer is 31.
Step-by-step explanation:
3² + (8 - 2) · 4 - 6/3
First, subtract 2 from 8.
3² + 6 · 4 - 6/3
Next, evaluate the exponent in 3².
9 + 6 · 4 - 6/3
Now, multiply 6 by 4.
9 + 24 - 6/3
Next, divide 3 from 6.
9 + 24 - 2
Add together 9 and 24.
33 - 2
Lastly, subtract 2 from 33.
33 - 2 = 31
So, your final answer for this equation is 31.
