Facts about pasical's education

Paha777 [63]

Blaise Pascal (June 19, 1623 - August 19, 1662) was a great contributor to math, science, and philosophy, especially Christian philosophy. Interesting Blaise Pascal Facts: Pascal's early education in France was conducted at home by his father due to the prodigious talent and understanding he showed as a child. Did u mean pascal instead of pasical becaus ethere is no such thing. Hope I helped :)

Find the perimeter of a circle whose radius is 3.5cm. (Take pi = 22/7)

mrs_skeptik [129]

Answer:

P = 44

Step-by-step explanation:

The formula for the perimeter (circumference) of a circle is;

C = πd

C = 2πr

C = 2π (3.5)2

C = 2π7

C = 2 * 22/7 * 7

C = 2 * 22

C = 44

Maria is monitoring the temperature of two substances in her science lab. Substance A is currently 96.2 and rising 1.4 each minu

lilavasa [31]

It would take 1.045 minutes for both substances to be at the same temperature.

Substance A started at a temperature of 96.2 and is rising at 1.4 every minute. Assuming minutes were denoted as x, the relevant expression would be:

<em>= Starting temperature + (Rate temperature is rising x number of minutes)</em>

= 96.2 + 1.4x

Substance B is reducing in temperature:

= 98.5 - 0.8x

<u>Equate both expressions:</u>

96.2 + 1.4x = 98.5 - 0.8x

1.4x + 0.8x = 98.5 - 96.2

2.2x = 2.3

x = 2.3 / 2.2

= 1.045 minutes

It would therefore take 1.045 minutes for both substances to be at the same temperature.

Find the A.P whose second term is 12 and 7th term exceeds the 4th by 15

Art [367]

The 2nd term exists 12 and 7th term exceeds the 4th by 15 exists AP : 7,12,17,....

<h3>How to estimate the arithmetic progression?</h3>

Given : The second term exists 12th and the 7th term exceeds the 4th term by 15

The formula of the nth term :

$$a_{n}=a+(n-1) d$

Where d exists a common difference

n be the number of terms

a be the first term

Substitute the value of n = 2

$$a_{2}=a+(2-1) d=a+d$

Let, the second term exists 12

So, a + d = 12 ..........(1)

Substitute the value of n = 7

$$a_{7}=a+(7-1) d=a+6 d$

Substitute n = 4

$$a_{4}=a+(4-1) d=a+3 d$

We are given that the 7th term exceeds the 4th term by 15

So, a+6d-a-3d = 15

3d = 15

d = 5

Substitute the value of d in (1)

So, a+5 = 12

a = 12-5

a = 7

AP : a,a+d,a+2d,.... = 5, 7+5, 7+2(5),....=7,12,17,....

Therefore, AP : 7,12,17,....
