Answer:

A) option c) about 12

B)  option a) about 9      

Step-by-step explanation:

We have to carry out the following calculation and use compatible numbers to evaluate,

A)

5\times 2\displaystyle\frac{3}{5}\\\\=5\times \frac{13}{5}\\\\=13

Hence, the answer option c) about 12.

B)

25\displaystyle\frac{7}{8}\div 2\frac{8}{9}\\\\=\frac{207}{8}\div \frac{26}{9}\\\\=\frac{207}{8}\times \frac{9}{26}\\\\= 8.95

Hence, the right answer is option a) about 9

The table shows a pattern of exponents.<br><br> What is the pattern as the exponents decrease?
Marrrta [24]

Answer:

Option C is correct.

Step-by-step explanation:

We need to find the pattern as the exponent decreases.

the first value in the table is 125.

if we divide 125 by 5 i.e 125/5 we get 25

the next value in the table is 25

if we divide 25 by 5 i.e 25/5 we get 5

the next value in the table is 5

if we divide 5 by 5 i.e 5/5 we get 1

the next value in the table is 1

if we divide 1 by 5 i.e 1/5 we get 1/5

the next value in the table is 1/5

if we divide 1/5 by 5 i.e 1/5*5 we get 1/25

the next value in the table is 1/25

So, the pattern is if we divide the previous value by 5 we get the next value in the table.

So, Option C is correct.

COME GET 50 POINTS!!
MArishka [77]

Answer:

Quadratic, because the height increases and then decreases.

Step-by-step explanation:

In an exponential function, the graph will either increase or decrease over the entire domain.  It does not change direction.

We can see from the table that the heights increase and then decrease; this means it cannot be an exponential function.

A quadratic function has a graph that is u-shaped.  It will start out either increasing or decreasing, and then after the maximum or minimum is reached, it changes direction.

We can see from the table that this is what the heights do; this means it is a quadratic function.
