Answer:
second one
s/(2πh) = r
Step-by-step explanation:
You want to put the unknown value you are solving on 1 side and rest on the other side. In this case, you have to have r alone on one side.
s=2πrh
Since they are all multiplied with r, you divide them all on both sides to send them to other side.
s/(2πh) = 2πrh/ (2πh)
cancel out right side and it leaves r alone.
s/(2πh) = r

The first three terms of a sequence are given. Round to the nearest thousandth (if necessary). Find the 49th term. 8, 14,20,. Hint its not 294
Answers
Answer: 296
Step-by-step explanation: explicit rule formula for an arithmetic sequence:
a_n = a_1 +(n-1)(d)
20-14= 6
d= 6
a_1 = 8
a_n = 8 + (n-1)(6)
= 8+6n-6
a_n= 6n+2
substitute to find answer:
a_49= 6(49) +2
= 294+2
=296

If a starting population size is 200 individuals and there are 20 births and 10 deaths per year, the per capita growth rate (r) is ____ and the new population size after one year will be
Answers
The per capita growth rate is 5% and the new population size after one year will be 210 individuals
What is an equation?An equation is an expression that shows the relationship between two or more variables and numbers.
The per capita growth rate is given as:
per capita growth rate = change in population / initial population = (20 - 10)/200 = 0.05 = 5%
In one year, population = 200 + (0.05 * 200) = 210
The per capita growth rate is 5% and the new population size after one year will be 210 individuals

Answer:
(-1 , -1)
Step-by-step explanation:
let D be the missing point

D lie on the line that passes through the point C and parallel to the line AB
Then D is the intersection of those two lines
Then D is the point of coordinates (-1 , -1)

DC
such that
DF = GC, and
A(F) ∩ BG = E. Prove that DE = CE.
(I had to put parentheses around the F or else Brainly would think I'm swearing, just so you know. )
Answers
The two sides are equal and for that reason DE = CE as shown below :
AD = BC, DF = GC
E = A(F) and E = BG, therefore A(F) = BF
Description of rectangle
Now we all know that a rectangle has four edges which are A, B, C, D.
when we divide the bottom line, which is the line from point C to D into three parts we will have ( DF, FG, and GC )
From the question we know that DF = GC
E is the intersection of A(F) and BG
we can now Prove that DE = CE.
since D and C are point included in E and since this is a rectangle
AD = BC, DF = GC
E = A(F) and E = BG, therefore A(F) = BF
DE = CE
We can conclude by saying that in a rectangle two sides are equal and for that reason DE = CE

What is the vertex form of parabola?Vertex form of parabola is the equation form of quadratic equation, which is used to find the coordinate of vertex points at which the parabola crosses its symmetry.
The standard equation of the vertex form of parabola is given as,
[tex]y=a(x-h)^2+k[/tex]
Here, (h, k) is the vertex point.
The function given in the problem is,
[tex]f(x) = 4+x^2 - 2x\\f(x) = x^2 - 2x+4[/tex]
Add and subtract (-1)² in the above function,
[tex]f(x) = x^2 - 2x+4+(-1)^2-(-1)^2\\f(x) = x^2 - 2x+(-1)^2+4-1[/tex]
Use the formula of whole square,
[tex]f(x)=(x-1)^2+3[/tex]
This is the required vertex form.
Hence, the vertex form which is equivalent to the provided quadratic function is (x-1)²+3.
