Answer:

Step-by-step explanation:

scale factor bigger than one, in math greater than, the figure is larger than the object being used a figure smaller than 1 creates a figure smaller than the original

Luckily you can just use your web browser to scale a screen up or down in it's scale. try it.. top right ellipse for go ogle chrome lets you scale over 100 per cent or 1 and also under 100 per cent or less than 1 remember 100 per cent = 1.00

Suppose a laboratory has a 26-gram sample of polonium-210.The half-life of polonium-210 is about days. a.How many half-lives of

vovangra [49]

Answer:

a) Two half lives, b) $m(276) = 6.526\,g$

Step-by-step explanation:

a) The polonium-210 has a half life of 138.4 days. Therefore, 1.994 half lives have past.

b) Mass decay is described by the following exponential model:

$m(t)=m_{o}\cdot e^{-\frac{t}{\tau} }$

The time constant for the isotope is:

$\tau = \frac{138.4\,days}{\ln 2}$

$\tau = 199.669\,days$

The mass of the isotope after 276 days is:

$m(276) = (26\,g)\cdot e^{-\frac{276\,days}{199.669\,days} }$

$m(276) = 6.526\,g$

Prime factorization of 48 is :

$48=2\times 2 \times 2 \times 2 \times 3\\\\=2^4\times 3^1$

Option (3) is true.

9.

Prime factorization of 19 is:

19 = 19 × 1

Option (c) is correct.

(10).

Prime factorization of 924 is:

924 = 2 x 2 x 3 x 7 x 11

= 2² x 3¹ x 7¹ x 11¹

Hence, this is the required solution.
