Answer + Step-by-step explanation:

your question is about equation 4 :

$b_{1}=14-b_{2}$

Then

$\left( b_{1}\right)^{2} =\left( 14-b_{2}\right)^{2} \ \text{(this is a special product )}$

Then

$\left( b_{1}\right)^{2} =14^{2}-2\times 14 \times b_{2}+ (b_2)^2$

Then

$\left( b_{1}\right)^{2} =196-28 b_{2}+ (b_2)^2$

Round to the nearest tenth if necessary

bagirrra123 [75]

Answer:

4. 7.8

Step-by-step explanation:

Let's find the distance between (-2,-1) and (3,5):-

D=√( x_1-x_2)^2+(y_1-y_2)^2

D= √(3+2)^2+(6)^2

D= √(61)

D= 7.8

Therefore, option 4 is your answer.

Hope this answers your question!!

The sequence 2, 3, 5, 6, 7, 10, 11, $\ldots$ contains all the positive integers from least to greatest that are neither squares

sergeinik [125]

The 400th term is 425.

There are floor(√400) = 20 squares in the range 1..400, so the 400th term will be at least 420. There are floor(∛420) = 7 cubes in the range 1..400, so the 400th term may be as high as 427. However, there are $\lfloor\sqrt[6]{427}\rfloor=2$ numbers that are both squares and cubes. Consequently, the 400th term will be 427-2 = 425.
