4. Entomologists introduce 20 of one
Lina20 [59]

Answer:

This number can be found using the Rule of 70, which describes the formula dt = 70 / r, where dt is the doubling time, and r is the annual rate of growth.

Step-by-step explanation:

24/6 = 4

20 x 2 = 40 x 2 = 80 x 2 = 160 x 2 = 320

20 ---> 320 in the first day.

Keep doing this equation. Multiply each day's end result by 2 four times for 9 more days.

Given that the expression 2x² -2.9x-3.6 can be factorized into the form 0.1(px+q)(rx+s), where p, q, r and s are integers, find
Nonamiya [84]

~~2x^2-2.9x-3.6\\\\=\dfrac{20}{10}x^2 - \dfrac{29}{10} x-\dfrac{36}{10}  \\\\=\dfrac 1{10} (20x^2 -29x -361)\\\\=0.1(20x^2-29x-36)\\\\=0.1(20x^2-45x+16x-36)\\\\=0.1[5x(4x-9)+4(4x-9)]\\\\=0.1(5x+4)(4x-9)\\\\\text{Where,}~ p=5, ~ q=4,~ r=4~,s=-9\\\\\text{Hence,}~ \\\\p+q+r+s \\\\ = 5+4+4 -9 \\\\=13-9 \\\\ =4

Help can u answer this
umka21 [38]

Answer:

c) 82

d) - 11

g)27

h)1000

k)11

l) 8

Step-by-step explanation:

{9}^{2}  + 1  \\  = (9 \times 9) + 1 \\  = 81 + 1 \\  = 82

{6}^{2}  -  {5}^{2}  \\  = (6 \times 6) - (5 \times 5) \\  = 36 - 25 \\  =  - 11

(1 + 2 {)}^{3}  \\  =  {3}^{3}  \\  = 3 \times 3  \times 3\\  = 27

(2 + 8 {)}^{3}  \\  =  {10}^{3}  \\  = (10 \times 10 \times 10) \\  = 1000

\sqrt{4}  +  {3}^{2}  \\  = 2 +  {3}^{2}  \\  = 2 + (3 \times 3) \\  = 2 + 9 \\  = 11

2 \times 5 -  \sqrt{4}  \\  = 10 -  \sqrt{4}  \\  = 10 - 2 \\  = 8
