Initially, there were only 86 weeds in the garden. The weeds grew at a rate of 8% each week. The following function represents t

dybincka [34]

The function is f(x) = 86(1.01)^7x; grows approximately at a rate of 1% daily

<h3>How to rewrite the function?</h3>

The function is given as:

f(x) = 86(1.08)^x

There are 7 days in a week.

This means that:

1 day = 1/7 week

So, x days is

x day = x/7 week

Substitute x/7 for x in

f(x) = 86(1.08)^(x/7)

Rewrite as:

f(x) = 86(1.08^1/7)^x

Evaluate

f(x) = 86(1.01)^x

In the above, we have:

r = 1.01 - 1

Evaluate

r = 0.01

Express as percentage

r = 1%

Hence, the function is f(x) = 86(1.01)^7x; grows approximately at a rate of 1% daily

Answer:

Step-by-step explanation:

28 students all give $128

so,

$\sqrt[28]{128}$ = v v=6

Each student gave 6 dollars. This is true due to the fact that

$\sqrt[28]{128}$ =6

In one town, 47% of all voters are Democrats. If three

34kurt

Answer:

The probability that the all three votes are Democrats

P(X=3) = 0.1038

Step-by-step explanation:

Step(i):-

Given that the all voters are democrats

The probability that the all voters are democrats

p = 47% =0.47

q = 1-p =1-0.47 = 0.53

Step(ii):-

Let 'X' be the random variable in binomial distribution

$P(X=r) = n_{C_{r} } p^{r} q^{n-r}$

The probability that the all three votes are Democrats

P(X=3) = 0.1038

n=3 and r=3

$P(X=3) = 3_{C_{3} } (0.47)^{3} (0.53)^{3-3}$

$P(X=3) = 1 (0.47)^{3}$

P(X=3) = 0.1038

Final answer:-

The probability that the all three votes are Democrats

P(X=3) = 0.1038

Sarah used 2.5 cups of cheese in a dish that serves 10 people. Amyn used 1.6 cups of cheese in a dish that serves 8 people.

Pavel [41]

Answer: 0.05 cup

Step-by-step explanation:

Divide 2.5 by 10 to find how much is in one of Sarah’s dish.

This gives you 0.25

Divide 1.6 by 8 to find how much is in one of Amyn's dish.

This gives you 0.2

Now minus 0.2 from 0.25.

This gives you 0.05 cup

Add (3x + 9 / 2x + 6) + (8x + 12 / x^2 + 6x + 9)

jenyasd209 [6]

Answer:

$\dfrac{3x^2+34x+51}{2x^2+12x+18}$

Step-by-step explanation:

$\dfrac{3x+9}{2x+6}+\dfrac{8x+12}{x^2+6x+9}= \\\\\\\dfrac{3(x+3)}{2(x+3)}+\dfrac{8x+12}{(x+3)(x+3)}$

To add these two fractions, you need to make the denominators equal:

$\dfrac{3(x+3)(x+3)}{2(x+3)(x+3)}+\dfrac{16x+24}{2(x+3)(x+3)}= \\\\\\\dfrac{(3x^2+18x+27)+(16x+24)}{2(x+3)(x+3)}= \\\\\\\dfrac{3x^2+34x+51}{2(x+3)(x+3)}= \\\\\\\dfrac{3x^2+34x+51}{2x^2+12x+18}$

Hope this helps!
