How would I solve this?

Answers

Answer 1

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

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

Suppose ABCD is a rectangle, F and G are points on

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.
