Answer: $4512 was the amount she borrowed.

Step-by-step explanation:

SI = 1692

R = 15% = 0.15

T = 30 months = 2.5 years

SI = PRT

1692 = P x 0.15 x 2.5

1692 = 0.375P

P = 1692 / 0.375

P = 4512

Answer:

Correct answer is

[tex]\text{Quotient of }\dfrac{a-3}{7}\div\dfrac{3-a}{21} = -3[/tex]

Step-by-step explanation:

Let us rephrase the given statement mathematically.

We are given the fractions as:

[tex]\dfrac{a-3}{7}[/tex]

to be divided by:

[tex]\dfrac{3-a}{21}[/tex]

To find:

[tex]\dfrac{a-3}{7}\div\dfrac{3-a}{21}[/tex]

Now, let us have a look at the division rule in fractions:

[tex]\dfrac{a}{b} \div \dfrac{c}{d}[/tex]

is equivalent to

[tex]\dfrac{a}{b} \times \dfrac{d}{c}[/tex]

In other words, we say that the second fraction [tex]\frac{c}{d}[/tex] is changed to [tex]\frac{d}{c}[/tex] and [tex]\div[/tex] is changed to [tex]\times.[/tex]

Now solving the given fraction by applying above rules:

[tex]\dfrac{a-3}{3}\div\dfrac{3-a}{21}[/tex]

[tex]\Rightarrow \dfrac{a-3}{7}\times \dfrac{21}{3-a}\\\Rightarrow \dfrac{a-3}{7}\times \dfrac{21}{-(a-3)}\\\Rightarrow \dfrac{1}{1}\times \dfrac{3}{-1}\\\Rightarrow -3[/tex]

So, correct answer is:

[tex]\text{Quotient of }\dfrac{a-3}{7}\div\dfrac{3-a}{21} = -3[/tex]

Answer:

x = - 1, y = 2

Step-by-step explanation:

Given the 2 equations

6x + 5y = 4 → (1)

19x + 2y = - 15 → (2)

Multiplying (1) by 2 and (2) by - 5 and adding will eliminate the term in y

12x + 10y = 8 → (3)

- 95x - 10y = 75 → (4)

Add (3) and (4) term by term thus eliminating y

- 83x = 83 ( divide both sides by - 83 )

x = - 1

Substitute x = - 1 into either of the 2 equations and evaluate for y

Substituting into (1)

6(- 1) + 5y = 4

- 6 + 5y = 4 ( add 6 to both sides )

5y = 10 ( divide both sides by 5 )

y = 2

if each the bonus is shared equally each will get 420

if 40% is shared by managers each manager will get 560

if 7 sales persons share 60% each will get 360

therefore Peter salesperson will get 360

but he thinks he will get 336 because if 420 is 125% that is including his extra 25% then hundred percent of the 420 is 336 which is not what he will get there for Janet is correct

Answer:

The 8ft tall pine tree will not affect the box plot here is why........

Outliers are important because they are numbers that are "outside" of the Box Plot's upper and lower fence, though they don't affect or change any other numbers in the Box Plot they are still important.

If you want to find your fences you will first take your IQR and multiply it by 1.5. I call this your "magic number".

Lower fence: Take your Q1 and subtract it from your magic number, that number your get is your lower fence.

Upper fence: Take your Q3 and add it to your magic number, that number you get is your upper fence.

-15x + 50x + 5 > 2

-15x + 50x > 2 - 5

35x > 2 - 5

35x > -3

x > -3/35

Answer: A. x > -3/35

Step-by-step explanation:

Answer:

A) f(x)

Step-by-step explanation:

f(x) has 4 x-intercepts, becoz it "cross" the x axis 4 times.

g(x) would have an infinite number of intercepts coz it is a cos function, but it gave a limit to the domain which is 0 to 2[tex]\pi[/tex], so it only has 2 x-intercepts.

h(x) is the degree of x^3, so in theory, it has 3 x-intercepts.

The function that has the most x-intercept is given by: Option A: f(x)

The x-intercept of a function of variable x ( y = f(x) ) form is an intersection fo the x-axis and the curve of the function.

The x-intercept for a function y = f(x) is a solution to the equation f(x) = 0 becuase at that value of x, the function f(x) lies on x-axis, where y is 0. Values of x-intercept for a function f(x) are also called roots or solution of f(x) = 0 equation.

Suppose that we've got a polynomial function as y = p(x),

where p(x) is of degree n (the highest power its variable pertains in any of its composing terms).

Then, the maximum number of roots it can possess for p(x) = c (c is a constant), or p(x) - c = 0 is n

So, the number of roots of p(x) - c = 0 cannot exceed the degree of p(x).

From the graph, we see that:

f(x) intersects x-axis at 4 places, so it has 4 x-intercepts.

g(x) intersects the x-axis at 2 places as in the graph, and therefore, it has 2 x-intercepts.

h(x) is a polynomial of degree 3. The maximum number of intercepts it can have is the maximum number of roots h(x) = 0 can have which is 3(the degree of h(x) ). So it cannot be bigger than 3.

Thus, the function that has the most x-intercept is given by: Option A: f(x)

Answer:

(b)[tex]P(t)=4.70(1.0136)^t[/tex]

(c)The price of milk next year will be: $4.76

(d)5 years

Step-by-step explanation:

The price of a gallon of milk has been rising about 1.36% per year since 2000.

(a)Since the price grows by a percentage (or constant factor) each year, an exponential function would be best to model the scenario.

(b)The exponential growth model is given as:

[tex]P(t)=P_0(1+r)^t$ where:\\P_0$=Initial Price\\r=Growth factor\\t=time (in years, for this case)[/tex]

The independent variable in the function is t. This represents the number of years since 2000.

(c)

[tex]I$nitial Price, P_0=\$4.70\\r=1.36\%=0.0136\\P(t)=4.70(1+0.0136)^t\\\\P(t)=4.70(1.0136)^t[/tex]

Therefore, the price of milk next year will be:

[tex]P(1)=4.70(1.0136)^1=\$4.76[/tex]

(d)We want to determine how long it will take for the price to top $5.

P(t)=$5

[tex]5=4.70(1.0136)^t\\$Divide both sides by 4.7$\\(1.0136)^t=\frac{5}{4.7} \\$Change to logarithm form\\t=Log_{1.0136}\frac{5}{4.7}\\t=4.58[/tex]

Therefore, in exactly 4.58 years, the milk price would be $5. Therefore, by the 5th year, the milk price would top $5.

Answer:

Step-by-step explanation:

c^2=81

Take the square root of both sides.

The square root of c^2 is c.

The square root of 81 is 9.

c=9

Answer:

C = 9 centimeters

Step-by-step explanation:

First, look at the area of a square, which formula is c^2 or in standard format - s^2. Thus, we can say, c^2 = 81. Then, we can simplify, and put c = √81. Since 81 is a perfect square, 9 *  9 = 81. Thus the answer is 9 centimeters.

Step-by-step explanation:

Answer:

The function for the outside temperature is represented by [tex]T(t) = 85\º + 15\º \cdot \sin \left[\frac{t-6\,h}{24\,h} \right][/tex], where t is measured in hours.

Step-by-step explanation:

Since outside temperature can be modelled as a sinusoidal function, the period is of 24 hours and amplitude of temperature and average temperature are, respectively:

Amplitude

[tex]A = \frac{100\º-70\º}{2}[/tex]

[tex]A = 15\º[/tex]

Mean temperature

[tex]\bar T = \frac{70\º+100\º}{2}[/tex]

[tex]\bar T = 85\º[/tex]

Given that average temperature occurs six hours after the lowest temperature is registered. The temperature function is expressed as:

[tex]T(t) = \bar T + A \cdot \sin \left[2\pi\cdot\frac{t-6\,h}{\tau} \right][/tex]

Where:

[tex]\bar T[/tex] - Mean temperature, measured in degrees.

[tex]A[/tex] - Amplitude, measured in degrees.

[tex]\tau[/tex] - Daily period, measured in hours.

[tex]t[/tex] - Time, measured in hours. (where t = 0 corresponds with 5 AM).

If [tex]\bar T = 85\º[/tex], [tex]A = 15\º[/tex] and [tex]\tau = 24\,h[/tex], the resulting function for the outside temperature is:

[tex]T(t) = 85\º + 15\º \cdot \sin \left[\frac{t-6\,h}{24\,h} \right][/tex]

Answer:

The correct answer will be "0.756596 m²".

Step-by-step explanation:

The given values are:

The radius of an umbrella,

r = 0.4 m

The height of an umbrella,

h = 0.45 m

As we know,

The lateral surface of an umbrella will be:

⇒  [tex]\pi r\sqrt{r^2+h^2}[/tex]

On substituting the values, we get

⇒  [tex]\pi \times 0.4\sqrt{(0.4)^2=(0.45)^2}[/tex]

⇒  [tex]0.756596 \ m^2[/tex]

So that the amount of fabric needed will be "0.756596 m²".

Tim was paid 15 for his overtime.

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

Normal pay of Tim= 10

Overtime hours= 4

and, overtime pay = 1 1/2 of 10

So, the overtime pay

= 3/2 of 10

= 3/2 x 10

= 15

Hence, Tim was paid 15 for his overtime.
