+= 34
The equation of a circle in standard form is
+=
where (a , b) are the coordinates of the centre and r is the radius
The centre is at the midpoint of the endpoints and the radius is the distance from the centre to either of the 2 endpoints
Using the midpoint formula
midpoint = [(x+, (+
where (,=(3,8) and (,=(-7,2)
centre = ((3-7),(8+2)) = (-2,5)
Calculate r using the distance formula
r = √(-)²+(-)²)
= √((3+2)²+(8-5)²) = √(25+9) = √34 ⇒ r² =(√34)² = 34
equation of circle is : (x+2)²+(y-5)² = 34
9 less means subtract
the product of 5 and the number n mea multiply 5 and n
D. 5n-9
Answer:
Step-by-step explanation:
Step 1:
Write the expression
Step 2: Expand
Step 3: Collect similar terms
Step 4: Factor 4 out of the expression to prove that the expression is a multiple of 4.
$1632
Given data
Principal= $1200
Rate= 12%
Time= 3 years
The simple interest expression is given as
A= P(1+rt)
substitute
A=1200(1+0.12*3)
A=1200(1+0.36)
A=1200*1.36
A=$1632
Hence the amount is $1632
$270.
Answer:ur answer is 96
