First you find P which would be 16+17+17 which equals 50. Then you find B which is 1/2•16•15 which equals 120. Next you write the formula which would look like 50(20)+2(120) which equals 1240!

<u>Answer</u>

C. 4 + 6

D. 3.15151515.. + 4.6

E. √64 × √25

<u>Explanation</u>

A rational number is a number that can be expressed as a quotient or a fraction. That is it can be written as a/b.


π×6 = 6π   ⇒ can not be written as a rational number.

√3 + √5 ⇒ the sum of two irrational numbers can not be rational.

4 + 6 = 10. Ten is a rational number. it can be written as 10/1

3.15151515.. + 4.6 = 104/33 + 23/5

                             = 1279/165                      

√64 × √25 = 8×5=40            This can be written as 40/1

For for each quadratic function below use method of completing the Square or averaging the x-intercept to write the equation in
lions [1.4K]

We have the expressions:

f(x)=x^2+6x+15y=x^2-4x+9f(x)=x^2-8xy=x^2+7x-2

Now, with this we operate as follows:

a)

f(x)=x^2+6x+15=x^2+6x+9+15-9\Rightarrow(x+3)^2+6

Then, the axis is x = -3 and the vertex (-3, 6)

b)

y=x^2-4x+9=x^2-4x+4+9-4\Rightarrow(x-2)^2+5

Then, the vertex is (2, 5) and the axis is x = 2.

c)

f(x)=x^2-8x+4-4\Rightarrow(x-2)^2-4

Then, the vertex is (2, -4) andd the axis is x = 2.

d)

y=x^2+7x-2=x^2+7x+\frac{49}{4}-2-\frac{49}{4}\Rightarrow(x+\frac{7}{2})^2-\frac{57}{4}

Then, the vertex is (-7/2, -57/4) and the axis is -7/2.

Answer:

24.8 inches

Step-by-step explanation:

Volume of a cylinder=πr²h

Where volume=774 and h=0.4

Now

774=(3.14)r²(0.4)

774=1.2566r²

Divide both sides by 1.2566

r²=615.94

Taking sq root on both sides

r=24.8 inches
