#9 75% of 1
#10 50% of 350 is
#11 What percent of 450 is 50

Answer:

lesser x = 9

greater x = 11

Step-by-step explanation:

(x-10)² - 1 = 0

(x-10)² = 1

(x-10) = +- root1 (positive and negative root1)

So (x-10) = +1 and (x-10) = -1

Firstly

X - 10 = 1

X = 11

Secondly

X - 10 = -1

X = 9

So you have x = 9, and x = 11

The smaller one is the lesser x (9)

The larger one is the greater x (11)

The value of quantity after 0.2 hours is, 960

Given that;

A quantity with an initial value of 480 grows exponentially at a rate such that the quantity doubles every 6 minutes.

We know that;

The exponential growth function is

A = A₀ (1 + r)ⁿ

Where, A= The number of quantity after t days

A₀ = initial number of quantity

r = rate of growth

n = time in minutes

A quantity with an initial value of 830 grows at a rate such that the quantity doubles in 0.2 hours = 12 minutes

And, A = 2 x 480 = 960

A₀ = 480

n = 12 minutes

r = ?

⇒ A = A₀ (1 + r)ⁿ

⇒ 960 = 480 (1 + r)¹²

⇒ 2 = (1 + r)¹²

⇒ [tex]r = \sqrt[12]{2} - 1[/tex]

Now, to find the quantity after 12 minutes, we plug A = 830, t = 12 minutes in exponential function;

⇒ A = A₀ (1 + r)ⁿ

⇒ [tex]A = 480 (1 + \sqrt[12]{2} - 1)^{12}[/tex]

⇒ A = 480 (2)

⇒ A = 960

Answer: B

Step-by-step explanation:

Ex: Shortest to smallest.

To find the ordered pair solutions for the system of equations y = -x² + 2 and y = x, we can set the two equations equal to each other:

-x² + 2 = x

Now we can rearrange this equation into standard quadratic form by moving everything to one side:

-x² + x + 2 = 0

We can solve this quadratic equation using the quadratic formula:

x = (-b ± √(b² - 4ac)) / 2a

where a = -1, b = 1, and c = 2

Plugging these values into the formula, we get:

x = (-1 ± √(1 - 4(-1)(2))) / 2(-1)

x = (-1 ± √9) / (-2)

x = (-1 ± 3) / (-2)

So the solutions for x are x = -1 and x = -2.

To find the corresponding values of y, we can plug these values of x into either of the original equations. Let's use y = x:

When x = -1, y = -1

When x = -2, y = -2

Therefore, the ordered pair solutions for this system of equations are (-1, -1) and (-2, -2).

The 50th partial sum of the given arithmetic sequence is 4600

From the question, we are to calculate the 50th partial sum of the given arithmetic sequence

The given arithmetic sequence is

-6, -2, 2, 6, ...

To find the 50th partial sum of the sequence, we will find the sum of the first 50 terms in the sequence.

The sum of n terms of a sequence is given by the formula,

S = n/2(a + l)

Where a is the first term

and l is the last term

l is given by

l = a + (n - 1)d

Where d is the common difference

In the given series

a = -6

d = -6 -(-2) = -6 + 2 = 4

Thus,

l = -6 + (50 - 1)4

l = -6 + 49×4

l = -6 + 196

l = 190

Then,

S = 50/2(-6 + 190)

S = 25(184)

S = 4600

Hence,

The sum is 4600

Answer:

 39 1/3 = 118/3 square units

Step-by-step explanation:

You want the area under the curve y = -x² +9x on the interval [3, 5].

The fundamental theorem of calculus tells us the integral of the function will be its anti-derivative. That is, for f(x) = -x² +9x, we want the function F(x) whose derivative is f(x). The reverse of the power rule for derivatives can be used:

  [tex]F(x)=-\dfrac{x^3}{3}+9\dfrac{x^2}{2}[/tex]

The area of interest is ...

  F(5) -F(3) = -1/3(5³ -3³) +9/2(5² -3²) = -98/3 +72

  F(5) -F(3) = 39 1/3

The area under the curve between x=3 and x=5 is 39 1/3 square units.

Answer:

Step-by-step explanation:

To find the total cost of interest, we first need to find the total payment over the life of the loan:

Total payment = Monthly payment x Number of payments

Total payment = $370.41 x (30 x 12)

Total payment = $133,347.60

Next, we need to subtract the principal (loan) amount to find the total interest paid:

Total interest = Total payment - Principal

Total interest = $133,347.60 - $69,000

Total interest = $64,347.60

Rounding to the nearest whole dollar, the total cost of interest is $64,348.

The 7th term of the binomial expression given can be found to be 8.136 × 10^7 × x^(-4)

To find the 7th term of (3x - 4/x²)¹⁴, we can use the binomial theorem, which states that for any positive integer n and any real numbers a and b:

(a + b)ⁿ = ∑(C(n, k) x a^(n-k) x b^k)

Using the binomial theorem formula, the 7th term can be calculated as follows:

Term_7 = C(14, 6) x (3x)^(14-6) x (-4/x²)^6

First, let's find C(14, 6):

C(14, 6) = 14! / (6! x (14-6)!)

C(14, 6) = 14! / (6! x 8!)

C(14, 6) = 3003

Now, we can put everything together:

The values of x , y and z in the parallelogram are 12, -20 and -33 respectively

A parallelogram is a quadrilateral with opposite side equal to each other and opposite sides parallel to each other.

The opposite angles of parallelogram are equal . Consecutive angles in a parallelogram are supplementary .

Therefore,

-4y + 5 = 85

-4y = 85 - 5

-4y = 80

divide both sides by -4

y = 80 / -4

y = - 20

Therefore, let's find x and z as follows:

8x - 1 + 85 = 180

8x = 180 - 84

8x = 96

divide both sides by 8

x = 96 / 8

x = 12

Let's find z

- 3z - 4 + 85 = 180

The average rate of change of the given function between the two given values is: 0.82

The Average Rate of Change of a function is one that is defined as the average rate at which one quantity is changing with respect to another thing changing. Thus, an average rate of change function is basically a process that helps to calculate the amount of change in one item divided by the corresponding amount of change in another.

It is given by the formula:

f'(x) = [f(b) - f(a)]/(b - a)

We are given the function:

f(x) = √(3x - 11)

Thus from x1 = 4 to x2 = 6, we will have:

f(4) = √(3*4 - 11) = 1

f(6) = √(3*6 - 11) = √7

a) We are interested in finding and reporting the prediction interval on the output.

Thus, the prediction interval on the output is [7.9188, 8.9025]

Let us consider the estimated value for y as yₓ

We know that yₓ = β₀ +β₁x₁ + β₂x₂ + β₃x₃

By substituting the value

x₁ = 3.7, x₂ =3.9, x₃ = 6.5, β₀= 7.5891, β₁ = -2.3577, β₂= 1.6122, β₃= 0.5012 into the above equation we get

yₓ =7.5891-(2.3577*3.7)+(1.6122*3,9)+(0.5012*6.5) = 8.411

Let us calculate the value for the prediction interval

The 100 (1 - a) \% prediction interval is

yₓ ±(tₐ/₂ * x * s* √ 1+distance value )

The distance value is the leverage value from the output which is 0.004

We have yₓ =8.411, t₀.₀₀₅.₂₆ =3.067 and s = 0.235. By substituting these values we find that the 95% prediction interval is

We are interested in calculating a 99% prediction interval for the demand of detergent in the future sales period

We have yₓ =8.411, t₀.₀₀₅.₂₆ =3.067 and s = 0.235 By substituting these values, we find that the 95% prediction interval is as follows

8, 411 ± (3.067 * 0.235sqrt(1 + 0.04)) = [7.676, 9.146]

The wildlife group can estimate that there are 100 wild hogs in the area. The answer is C.

The basic idea behind this method is that if we capture a random sample of animals from a population, tag them, and release them back into the population, then later capture another sample of animals, the ratio of tagged to untagged animals in the second sample can be used to estimate the total population size.

To estimate the total population of wild hogs in the area, we can use the capture-recapture method.

In this case, the wildlife group tagged and released 20 wild hogs, and later counted 8 wild hogs out of the 40 they saw. We can set up a proportion to estimate the total population size:

(Tagged hogs in first sample) / (Total population size) = (Tagged hogs in second sample) / (Number of hogs in second sample)

Putting the values,

⇒ 20 / x = 8 / 40

Simplifying and solving for x, we get:

⇒ x = (20 × 40) / 8 = 100

⇒ x = 100

Therefore, the wildlife group can estimate that there are 100 wild hogs in the area. The answer is C.
