Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions.

To estimate the sum or difference of 8/9 + 4/7 it should be 1 1/2

It is also a way to find an approximate answer to a solution. To estimate products and quotients of mixed numbers, round the fractions to the nearest whole number. If the fraction is less than 12 round down and if it is more than 12 round up. First, since 411 is less than 12,8411 rounds down to 8.

Answer

the estimated sum is 11.59

And the estimated difference is

0.32

Step-by-step explanation:

The question bothers to know how well you understand your fraction

In a step by step approach we will estimate both the sum and the difference

Step one

Let us know what the sum is

8/9+4/7

The Lcm can be gotten by multiplying the denominators

9x7=63

56+36/63= 92/63

=11.59

Hence the estimated sum is 11.59

Step two

Let us estimate the difference also we have

8/9-4/7

Like before our Lcm =63

56-36/63=20/63

=0.32

Our estimated difference is 0.32

The number of members over time in an online music sharing club can be modeled by an exponential function. the club started with

Paraphin [41]

Answer:

a.) $N(x) = N_{0} e^{bx}$

b.) therefore b = $\ln \frac{2142}{2100} = \ln (1.02) = 0.0198$

b is the rate of increase of number of members

c.) The club will not be able to get more than 5000 members during its first year.

Step-by-step explanation:

i) the club started with 2100 members.

so we can write $N_{0}$ = 2100.

a.) so we can write the equation as an exponential function given by

$N(x) = N_{0} e^{bx}$ where x is in months and b is a constant and N(x) is the number of members in the online music sharing club .

therefore 2142 = 2100 $\times (e^{b\times 1})$ = 2100 $e^{b}$

b.) therefore b = $\ln \frac{2142}{2100} = \ln (1.02) = 0.0198$

b is the rate of increase of number of members

c.) Will the club have more than 5000 members during its first year? Justify your reasoning.

5000 = 2100 $e^{0.0198x}$

therefore x = $\frac{1}{0.0198} \ln{(\frac{5000}{2100} )} = 43.81 \hspace{0.1cm}months$

The club will not be able to get more than 5000 members during its first year.

Use the discriminant to determine the number and type of solutions the equation has.

lidiya [134]

Discriminant = square root (b^2 -4*a*c)
square root (64 -4*1*12) =
square root (16) =
4
Therefore it has 2 rational soltions
