Answer:
45
Step-by-step explanation:
3 over 2 so then you take the 30 over 1 then the 2 at the bottom you divide the 30 and the 2 and you get 15 then you take the 15 times 3 and that is your answer 45.
Answer:
40% decrease
Step-by-step explanation:
First, let's find the value decrease of the item from yesterday to today
$65 - $39 = $26
That means that $65 was 100% of the price and decreasing it by 26 gets us to 39
We need to find the percentage of 39 in 65
39/65 = 0.6 or 60%
If 39 is 60% of 65, then there was a 40% decrease form 100%
To check we can calculate the percentage of 26 in 65:
26/65 = 40%
There was a 40% decrease

Answer:
Step-by-step explanation:
Without the variable x, your "f(x) = 3(18)*" is not a function. If you meant
f(x) = 3(18)^x, then the domain is "the set of all real numbers," and the range is (0, infinity).
the initial value is 3: f(0) = 3(18)^0 = 3(1) = 3

Sub-greater radical equals 0 /d
Step-by-step explanation:
The standard forrm equation of the circle is (x-h)² + (y-k)² = r²
where h,k : x,y-coordinate of the center
r : radius of the circle
Get the center of the circle : h = (x1 + x2)/2 = (9+5)/2 = 7
k = (y1 + y2)/2 = (4+2)/2 = 3
=> the center is (7,3)
Because the given information gave 2 endpoints so we can choose one of these, then use the distance formula to get the radius
r = √(x1 - h)² + (y1 - k)²
r = √(9 - 7)² + (4 - 3)²
r = √2² + 1²
r = √5
Finally, the equation of the circle is (x - 7)² + (y - 3)² = (√5)²
(x - 7)² + (y - 3)² = 5
