Answer:

Step-by-step explanation:

Paragraph proof:

Although there are three types of proofs namely

1) Two column proof

2) paragraph proof

3) flow chart proof

the paragraph proof is used to prove using sentences written in a paragraph.

It is a logical argument using sentences by giving evidences and details which lead to the conclusions.

Writing paragraph proof can be compared to solving a puzzle step by step.

This will have normally

Given, diagrams, prior knowledge in connection with proof, logical arguments and conclusions

The Johnson twins were born four years after their older sister. This year, the product of the three siblings ages is exactly 34

svp [43]

Answer:

Step-by-step explanation:

Let age of each twin be x

let age of sister be s

So we can write:

x + 4 = s

The product of the 3 siblings ages is 3482 more than sum. We can write:

$s*x*x=3482+(s+x+x)$

This can be simplified as:

$sx^2=3482+s+2x$

We replace s with "x + 4" and solve:

$(x+4)x^2=3482+x+4+2x\\x^3+4x^2=3486+3x\\x^3+4x^2-3x-3486=0\\x=14$

Note: To solve this cubic, we used technology

Thus, we can say the twins are 14 years old

Calculate the volume of the cylinder.Round your answer to the nearest hundredth 6cm height and 2cm width

Anvisha [2.4K]

Assuming width=diameter
diameter/2=radius

area=hpir^2

w=d=2
d/2=2/2=1=r
h=6

area=6pi1^2
area=6pi1
area=6pi
aprox pi=3.141592
area=18.85 cm³

Rewrite the function f(x)=-4(x-3)^2+16 in the form f(x)=ax^2+bx+c

elena55 [62]

Answer:

f(x) = - 4x² + 24x - 20

Step-by-step explanation:

Given

f(x) = - 4(x - 3)² + 16 ← expand the factor using FOIL

= - 4(x² - 6x + 9) + 16 ← distribute parenthesis by - 4

= - 4x² + 24x - 36 + 16 ← collect like terms

= - 4x² + 24x - 20
