S_A_V [24]

Answer:

30+4+0.7+0.05

Step-by-step explanation:

Because the expanded form is added the number.

3=30

4=4.

7=0.7

and 5=0.05 so all together is 30+4+0.7+0.05

If a = √3-√11 and b = 1 /a, then find a² - b²​
Serga [27]

If b=\frac1a, then by rationalizing the denominator we can rewrite

b = \dfrac1{\sqrt3-\sqrt{11}} \times \dfrac{\sqrt3+\sqrt{11}}{\sqrt3+\sqrt{11}} = \dfrac{\sqrt3+\sqrt{11}}{\left(\sqrt3\right)^2-\left(\sqrt{11}\right)^2} = -\dfrac{\sqrt3+\sqrt{11}}8

Now,

a^2 - b^2 = (a-b) (a+b)

and

a - b = \sqrt3 - \sqrt{11} + \dfrac{\sqrt3 + \sqrt{11}}8 = \dfrac{9\sqrt3 - 7\sqrt{11}}8

a + b = \sqrt3 - \sqrt{11} - \dfrac{\sqrt3 + \sqrt{11}}8 = \dfrac{7\sqrt3 - 9\sqrt{11}}8

\implies a^2 - b^2 = \dfrac{\left(9\sqrt3 - 7\sqrt{11}\right) \left(7\sqrt3 - 9\sqrt{11}\right)}{64} = \boxed{\dfrac{441 - 65\sqrt{33}}{32}}

A supermarket finds that the number of boxes of a new cereal sold increases each week. in the first week, only 16 boxes of the c
vaieri [72.5K]
For this case, the arithmetic sequence is given by:
 an = 17n-1
 Let's check it:
 First week:
 n = 1:
 a1 = 17 (1) -1
 a1 = 17-1
 a1 = 16
 Second week:
 n = 2:
 a2 = 17 (2) -1
 a2 = 34-1
 a2 = 33
 Third week:
 n = 3:
 a3 = 17 (3) -1
 a3 = 51-1
 a3 = 50
 Answer:
 
the explicit rule for the arithmetic sequence that defines the number of boxes of cereal sold in week n is:
 
an = 17n-1
