2 answers:

3 0

Find 25% of 52 first:

0.25 * 52 = 13

Now add this to the original amount:

52 + 13 = 65

So there are 65 companies after the increase.

Find 25% of 52, which would be multiplying 0.25 x 52, which gives us 13. We add 13 to 52 to get our final answer, which is 65. :)

How can you tell when a pattern shows counting on by tens?

velikii [3]

Answer:
The difference between successive terms is 10

Explanation:
To know the factor by which a certain pattern is increasing/decreasing, you need to subtract its successive terms.

If the subtraction gives you 10, this means that the pattern is increasing by 10

Examples:
10, 20, 30, 40, 50, .....
20 - 10 = 10
30 - 20 = 10
40 - 30 = 10
50 - 40 = 10
The difference between each two successive terms is 10. This means that each time we add 10 to the number we have in order to get the next one.
Therefore, this pattern is increasing by 10

37, 47, 57 , .....
47 - 37 = 10
57 - 47 = 10
The difference between each two successive terms is 10. This means that each time we add 10 to the number we have in order to get the next one.
Therefore, the pattern is increasing by 10

Hope this helps :)

The function f(x) = 7(1.32)x models the number, in billions, of the DNA sequences in a database x years since 2010. What does th

NikAS [45]

Answer:

The correct option is (A).

Step-by-step explanation:

The function representing the growth of number, in billions, of the DNA sequences in a database x years since 2010 is:

$f(x)=7\cdot (1.32) x$

The general growth function can be represented as:

$y=a\cdot (1+r)^{t}$

Here,

y = final value

a = initial value

r = growth rate

t = time

Com-paring the two functions we get:

$1+r=1.32\\r=1.32-1\\r=0.32$

This implies that the annual increase rate in number, in billions, of the DNA sequences is 32%.

Thus, the correct option is (A).
