Simple interest calculates interest on initial amount only. The investment by Hannah was : Option A: $4800

Suppose that the initial amount of investment is P

And the rate of simple interest is R% annually,

And the time of investment is T years.

Then, the amount of simple interest is calculated as:

[tex]I = \dfrac{P \times R \times T}{100}[/tex]

For the given case, let the initial investment Hannah made was of $P

Then, the time of investment is T = 8 years, R% = 4%, and given that Hannah earned interest I = $1536

Putting values in the above formula, we get;

[tex]I = \dfrac{P \times R \times T}{100}\\\\1536 = \dfrac{P \times 8 \times 4}{100}\\\\P = \dfrac{153600}{32} = 4800[/tex]

Thus,

The investment by Hannah was : Option A: $4800

Answer:

8x² + 4x - 10

Step-by-step explanation:

     We will use the order of PEMDAS to solve

-> See attached

(6x+7) (3x-1) - (5x+3) (2x+1)​

   (6x+7) (3x-1) becomes 18x² - 6x + 21x - 7 which is equal too 18x² + 15x - 7

   (5x+3) (2x+1)​ becomes 10x² + 6x + 5x + 3 which is equal too 10x² + 11x + 3

(18x² + 15x - 7) - (10x² + 11x + 3)

   18x² - 10x² = 8x²

   15x - 11x = 4x

   -7 - 3 = -10

Answer:

Train A = 299 tons Train B = 50 tons

Step-by-step explanation:
Train A = x

Train B = y

x+y = 349

x= y +249

Plug in one equation into another

y+249+y= 349

Simplify

2y+249=349

Subtract 249 from both sides

2y=100

Divide both sides by 2

y=50

Plug it into the x equation to solve for x

x+50=349

-50 from both sides

x=299

Sin function goes up and down, standard amplitude is 1 unit. The sin function modelling the given situation is [tex]f(x) = 30\sin(\dfrac{\pi x}{5}) + 90[/tex]

Suppose that we've got

[tex]f(x) = a\sin(bx + c) + d[/tex]

It has got

The situation given has:

Maximum blood pressure as 120 mm/Hg = a + d

Minimum blood pressure as 60 mm/Hg = -a + d

Thus, adding both will give:

[tex](a+d) + (-a + d) = 120 + 60\\2d = 180\\d = 90[/tex]

Thus, as a + d = 120, thus, a = 120-d = 120 - 90 = 30

Now, The period is given to  be 10 minutes, or we get:

[tex]\dfrac{2\pi}{b} = 10\\\\b = \dfrac{\pi}{5}[/tex]

Since count started from 0, thus, c= 0

Therefore, the sine function modelling the given situation is:

[tex]f(x) = a\sin(bx + c) + d \\\\f(x) = 30\sin(\dfrac{\pi x}{5}) + 90[/tex]

Here x is the number of minutes passed.

Product of two polynomials can be done by distribution of multiplication over addition. The product of  [tex]-2x^2(x+6)[/tex] is [tex]-2x^3 - 12x^2[/tex]

Suppose a, b and c are three numbers. Then we have:

[tex]a(b + c) = a\times b + a\times c[/tex]

(a(b+c) means a multiplied to (b+c). The sign of multiplication is usually hidden when using symbols and both quantities which are in multiplication are written together without space)

The product result of the given expression is

[tex]-2x^2(x+6) = -2x^{2+1} -12x^2 =-2x^3 -12x^2[/tex]

It is because when bases are same and there is multiplication, then powers add up, so we have: [tex]a^b \times a^c = a^{b+c}[/tex]

Also, we've

[tex](-ve \times (+ve) = -ve\\(-ve) \times (-ve) = +ve\\(+ve) \times (+ve) = +ve\\(+ve) \times (-ve) = -ve[/tex]

where -ve, +ve are sign of operands and result.

That's why [tex]-2 \times 6 = -12[/tex]

Thus,

The product of  [tex]-2x^2(x+6)[/tex] is [tex]-2x^3 - 12x^2[/tex]

The cost the company budget on average for a gallon of fuel across its operations is given by: Option D: $3.70

A  random variable is usually taking some numerical information of each elementary event of the sample space . (map from sample space to real numbers). Its expected value is the best prediction value in most of the cases. It is the mean or average value of that random variable.

Supposing that the considered random variable is discrete, we get:

[tex]Mean = E(X) = \sum_{\forall x_i} f(x_i)x_i\\\\[/tex]

where [tex]x_i; \: \: i = 1,2,.. , n[/tex] is its n data values

and  [tex]f(x_i)[/tex] probability of [tex]X = x_i[/tex]

Percent counts the number compared to 100 whereas probability counts it compare to 1.

So, if we have a%, that means for each 100, there are 'a' parts. If we divide each of them with 100, we get:

For each 1, there are a/100 parts.

Thus, 50% = 50/100 = 0.50 (in probability)

If assuming that X = Fuel cost per gallon, then

E(X) = Average fuel cost per gallon that the company should budget (its per gallon, means for a gallon)

Using the tabulated value given in the problem, we get:

[tex]Mean = E(X) = \sum_{\forall x_i} f(x_i)x_i\\\\\\\\E(X) = 3.10 \times 0.2 + 3.5 \times 0.3 + 4.05 \times 0.5 = 3.695 \approx 3.70[/tex] (in dollars)

(we converted percentage to probability).

Thus, the cost the company budget on average for a gallon of fuel across its operations is given by: Option D: $3.70

Answer:

Sally would have to drive 180 mi in a workweek.

Step-by-step explanation:

You multiply the number of miles it takes her to get to her job by how many times she drives to and from work a day. (She drives 18 mi to work and 18 to get home) (18•2=36) So she drives 36 mi in one day. Then you multiply the number of miles she drives per day (36) by how many days she works a week (5) and you get 180 mi in a workweek.

Step-by-step explanation:

Pi has an infinite number of digits, but you don't need very many of them to answer the question!

[tex]\pi \approx 3.14[/tex] (the symbol  [tex]\approx[/tex]  means "approximately equal to").

The quantity [tex]3\pi + 5 \approx 3(3.14)+5=9.42+5=14.42[/tex].  In other words, you are looking for a point between 14 and 15.  It's point A.
