Answer:

The next term is 64, a is 2, and the common ratio is 2.

Step-by-step explanation:

Look at what's happening from each number to the next. What do you need to do to get from 2 to 4, or 4 to 8? Multiply by 2. That's your common ratio. To get the next number in the sequence, multiply the last number by the common ratio of 2. 32 x 2 = 64, so the next number in the sequence is 64. "a" is just the very first term, meaning it's 2.

What is the domain of the function f(x) 2/5 startroot x = ? all real numbers all real numbers less than 0 all real number less t

lina2011 [118]

Answer:

$\boxed{\sf all \ real \ numbers \ greater \ than \ or \ equal \ to \ 0}$

Step-by-step explanation:

The domain of a function is all possible values for x.

$\sf f(x)=\frac{2}{5} \sqrt{x}$

There are restrictions on x.

The square root of a number can be undefined if that number is less than 0.

The value of x is all real numbers greater than or equal to 0.

Tiffany sees this given dilation and claims that the scale factor is 2

Alenkinab [10]

Answer:

The scale factor is not 2

Step-by-step explanation:

Given

See attachment for the dilated triangles

Triangle ABC is dilated through center point O to form triangle A'B'C'.

From the attachment, we have:

$OC = 2$ i.e. the distance from the center point to C

and

$OC' = 6$ i.e. the distance from the center point to C'

The length of OC' is calculated using:

$OC' = OC + CC'$

$OC' = 2 + 4$

$OC' = 6$

The scale factor (k) is then calculated by dividing OC' by OC

$k = \frac{OC'}{OC}$

$k = \frac{6}{2}$

$k = 3$

Hence, Tiffany's claim is incorrect.

The population of algae in an experiment has been increasing by 5% each day. If there were 5p algae at the beginning of the expe

Ostrovityanka [42]

Answer:

Number of algae in 7 days = 70.355

Step-by-step explanation:

Given:

Algae in beginning = 50

Rate of increasing = 5% per day = 0.05

Number of days = 7 days

Find:

Number of algae in 7 days.

Computation:

$Number\ of\ algae\ in\ 7\ days = Algae\ in\ beginning(1+Rate\ of\ increasing)^{Number\ of\ days}\\\\Number\ of\ algae\ in\ 7\ days = 50(1+0.05)^7\\\\Number\ of\ algae\ in\ 7\ days = 70.355$

Number of algae in 7 days = 70.355
