Answer:

  positive

Step-by-step explanation:

The exponent 12 tells you how many times (-1 3/4) is a factor in the product. The number 12 is even, so there will be an even number of minus signs in the product. That results in a positive product.

Answer:

1 and 17/25

Step-by-step explanation:

First, you make it into a fraction. So because percents are out of 100, it would be 168/100. Then, you take 100 out of it to get a mixed number, 1 and 68/100, and then simplify 68/100 by dividing both sides by the greatest common factor, which is 4. 68/100÷4=17/25. The answer would be 1 and 17/25.

Answer:

9

Step-by-step explanation:

f(11) means that x = 11 (plug it in)

f(11) = 1/4(5-11)^2

      = 9

The value of f(11) is 9.

The function of a given term is a form of an expression where element of the domain consists of a unique identity and each input value of a function is allocated to only one output value.

From the parameters given;

[tex]\mathbf{f(x) = \dfrac{1}{4}(5 - x)^2}[/tex]

we are to replace x with 11 wherever we see x

∴

[tex]\mathbf{f(11) = \dfrac{1}{4}(5 - 11)^2}[/tex]

[tex]\mathbf{f(11) = \dfrac{1}{4}(-6)^2}[/tex]

[tex]\mathbf{f(11) = \dfrac{1}{4} \times 36}[/tex]

f(11) = 9

Answer:

x = anything lower than 1

Step-by-step explanation:

x < 1

The constraint of inequality 3t - 12 < -9 is t < 1 and has been plotted on a number line.

A mathematical phrase in which the sides are not equal is referred to as being unequal. In essence, a comparison of any two values reveals whether one is less than, larger than, or equal to the value on the opposite side of the equation.

In other words, inequality is just the opposite of equality for example 2 =2 then it is equal but if I say 3 =6 then it is wrong the correct expression is 3 < 6.

Given the inequality

3t - 12 < -9

Add 12 on both sides

3t - 12 + 12 < -9 + 12

3t < 3

Divide by 3 into both sides

t < 1

Hence "The constraint of inequality 3t - 12 < -9 is t < 1".

Answer:

22 * n + 4

Step-by-step explanation:

Answer:

P(x) = 5.15 x + 1500

Step-by-step explanation:

The monthly operating costs = $1500 plus $0.85 per delivery.

The service generates revenue= $6 for each delivery

If in a given month the deliveries number was = x  then;

Operating cost  function : C(x) = 0.85x + 1500

Revenue generated function R(x) = 6x

Profit = Revenue - cost

P(x) = R(x) - C(x)

P(x) = 6x - 0.85x + 1500

P(x) = 5.15 x + 1500

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

[tex]P(X=r) = n_{C_{r} } p^{r} q^{n-r}[/tex]

The  probability that the all three votes are  Democrats

P(X=3) = 0.1038

n=3 and r=3

[tex]P(X=3) = 3_{C_{3} } (0.47)^{3} (0.53)^{3-3}[/tex]

[tex]P(X=3) = 1 (0.47)^{3}[/tex]

P(X=3) = 0.1038

Final answer:-

The  probability that the all three votes are  Democrats

P(X=3) = 0.1038

Answer:

C

Step-by-step explanation:

Ivy says:

f(1) = -100

You do that with the other numbers in the sequence. 2 = -50, 3 = 0 and so on

When you to n as 1, 2, and 3 they seem to all check out. So Ivy is right!

Andrey says:

That's a little suspicious don't you think that both answers are right..

Essentially they are both the same equation!

So let's simplify Ivy's equation!

f(n) = -100 + 50( n - 1 )

f(n) = -100 + 50n - 50

f(n)= -150 +50n

Which is basically Andrey's equation and they both seem to be right for the sequence! So both of them are right!

Step-by-step explanation:

Answer:

≈0.52

Step-by-step explanation:

The value of the quantity after 8.7 decades is 0.521.

Exponential growth is the increase of rate of change and thus results in the increase of the final quantity.

Exponential decay is the decrease in rate of change and hence results in the decrease of the final quantity.

Given that,

Initial value of the quantity = 230

Rate of decay = 7% per year = 0.07

Time = 8.7 decades = 87 years

The formula for exponential decay is,

A = P e^(-k t)

Here A is the final value of the quantity

P is the initial value of the quantity

k is the decay rate

t is the time.

Substituting the given values,

A = 230 × e^(-0.07 × 87)

A = 230 × e^(-6.09)

   = 0.521

Hence the final quantity after 8.7 decades is 0.521.
