Answer:

A

Step-by-step explanation:

there is not much more to say.

the point where actually all 3 line bisectors intersect, is also called the "circumcenter". I guess you understand what that means : it is the center of the circle circumscribing the whole triangle (passing through all 3 corners/vertices).

once you find that point with 2 line bisectors, there is no need to construct the third - it WILL intersect the others at the same point.

Answer: To apply l'Hospital's Rule, we need to take the derivative of the numerator and denominator separately with respect to θ.

Taking the derivative of the numerator:

d/dθ [1 - sin(θ)] = -cos(θ)

Taking the derivative of the denominator:

d/dθ [1 + cos(6θ)] = -6 sin(6θ)

Now we can apply l'Hospital's Rule by taking the limit of the ratio of the derivatives:

lim θ→π/2 (-cos(θ)) / (-6 sin(6θ))

When θ approaches π/2, cos(θ) approaches 0 and sin(6θ) approaches 1. Therefore, the limit simplifies to:

= 0 / (-6)

= 0

Hence, the limit of (1 - sin(θ)) / (1 + cos(6θ)) as θ approaches π/2 is 0.

To determine whether the series ∑(n=1 to infinity) 7n/n is convergent or divergent, we can apply the ratio test. The ratio test helps us determine the convergence or divergence of a series by examining the limit of the ratio of consecutive terms.

In this case, let's calculate the ratio of consecutive terms using the formula for the ratio test:

lim(n→∞) |(7(n+1)/(n+1))/((7n/n)|

Simplifying the expression, we get:

lim(n→∞) |7(n+1)/n|

As n approaches infinity, the limit evaluates to:

lim(n→∞) |7(n+1)/n| = 7

Since the limit is a finite positive value (7), which is less than 1, the ratio test tells us that the series is convergent.

However, you mentioned identifying an (term) in the series, and it seems there may be an incomplete part of the question. Please provide additional information or clarification about identifying an term in the series so that I can provide a more specific answer.

Answer:

250 × 0.25

Step-by-step explanation:

x/250 × 25/100

cross multiply

100x = 250 × 25

100x = 6250

divide by 100

x = 62.5

62.5 is how much the price got marked down

original price - marked down amount = new discounted price

250 - 62.5 = 187.5

$187.50 is now the actual price

As for which expression can be used to find the marked down price, none are listed in this problem and I'm assuming its a multiple choice question considering the wording of "which"

how i solved it is through cross multiplication but another way is by using the expression:

250 × 0.25

this is because 25% equals 0.25

Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.

Here,
For the best comparison between the function we need to evaluate the slope of each function,
So,
slope of function f(x) = 40 - 10  / 2 - 1
slope of function f(x) = 30 / 1

Now,
slope of function g(x) = 12 - 6  / 2 - 1
slope of function g(x) = 6 / 1

So, the slope of function f(x) is greater than the slope of function g(x).

Rounded to four decimal places, the answer is 0.7595, which is closest to option (a) 0.7598.

To find the total area between z=-0.75 and z=2.21, we need to find the area under the standard normal curve between these two z-values.

Using the standard normal table, we can find the area under the curve to the left of z=2.21 and subtract the area under the curve to the left of z=-0.75, as follows:

Area between z=-0.75 and z=2.21 = Area to the left of z=2.21 - Area to the left of z=-0.75

From the standard normal table, we can find that the area to the left of z=2.21 is 0.9861, and the area to the left of z=-0.75 is 0.2266.

Therefore, the total area between z=-0.75 and z=2.21 is:

Area between z=-0.75 and z=2.21 = 0.9861 - 0.2266 = 0.7595

Rounded to four decimal places, the answer is 0.7595, which is closest to option (a) 0.7598.

Option D. Interaction refers to the dependence or relationship between two independent variables in a statistical model.

It occurs when the effect of one independent variable on a dependent variable depends on the level or value of another independent variable. In other words, the relationship between the dependent variable and one independent variable is not the same for all levels of the other independent variable.

   then g (110) =   sqrt (110)

After approximately 12.13 years, the revenue of this firm is going to drop to $1 million.

The value of shares t years after their floatation on the stock market, is modelled by V = 10e0.09t

The initial value of shares = V when t = 0. So, putting t = 0 in V = 10e0.09t,

we get

V = 10e0.09 × 0= 10e0 = 10 × 1 = 10 million dollars.

The values after 5 years, 10 years and 12 years, respectively are:

For t = 5, V = 10e0.09 × 5 ≈ 19.65 million dollarsFor t = 10, V = 10e0.09 × 10 ≈ 38.43 million dollarsFor t = 12, V = 10e0.09 × 12 ≈ 47.43 million dollars

The total revenue (TR) in t years' time is modelled as TR = 10e−0.19t (in million dollars)

The current revenue is the total revenue when t = 0.

So, putting t = 0 in TR = 10e−0.19t, we get

TR = 10e−0.19 × 0= 10e0= 10 million dollars

Revenue in 5 years' time is TR when t = 5.

So, putting t = 5 in TR = 10e−0.19t, we get

TR = 10e−0.19 × 5≈ 4.35 million dollars

To find when the revenue of this firm is going to drop to $1 million, we need to solve the equation TR = 1.

Substituting TR = 1 in TR = 10e−0.19t, we get1 = 10e−0.19t⟹ e−0.19t= 0.1

Taking natural logarithm on both sides, we get−0.19t = ln 0.1 = −2.303

Therefore, t = 2.303 ÷ 0.19 ≈ 12.13 years.

So, after approximately 12.13 years, the revenue of this firm is going to drop to $1 million.

A Circle is a closed plane geometric shape figure. The diameter of a circle is the longest chord of a circle. The radius drawn perpendicular to the chord bisects the chord. A Circle is always lie at an equal distance from a center point. Circles having different radius are similar.

The area of a circle is pi times the radius squared. The unit of area of circle is square units.

\(\longrightarrow Area_{(circle)} = \pi r^2\)

Here, r is the radius of the circle.

We are asked to find the area of the circle in terms of pi if the diameter is 7 inches.

We know that, the diameter is twice the length of the radius of a circle. Therefore;

Now the area of circle will be:

\(\implies Area_{(circle)} = \pi r^2\)

\(\implies Area_{(circle)} = \pi (3.5)^2\)

\(\implies Area_{(circle)} = 12.25 \pi\)

Hence, the area of the given circle is 12.25π square inches.

Answer:

Step-by-step explanation:

In the question we are given that diameter of circle is of 7 inches . And we have asked to find the area of the circle in term of pi ( π ) .

For finding area of circle we must have to know that what is the formula for finding area of circle. So :

\( \qquad \qquad \: \red{\underline{\red{ \boxed{ \frak{Area \: of \: Circle = \pi r {}^{2} }}}}}\)

Where ,

Solution : -

As in the question we are given length of diameter . So for finding area we need to find the radius of circle .

We know that diameter of circle is two times its radius or ,

\( \qquad \: \rm {Diameter = 2 × Radius }\)

So for radius we are dividing both side with 2 :

\(\qquad \: \rm { \dfrac{Diameter}{2} = \dfrac{ \cancel{2} × Radius}{ \cancel{2}} }\)

We get that ,

\( \qquad \: \rm {Radius = \dfrac{Diameter}{2} }\)

Therefore , we can say that radius of circle is half of its diameter .

Now using this firstly we are finding radius of circle . So :

\( \longmapsto \quad \: \boxed{\rm{ Radius = \frac{7}{2} \: \: inches}}\)

Now , we are moving towards our final solution .

So ,

\( \longrightarrow \quad \: Area_ { (Circle)} = \pi( \dfrac{7}{2} ) {}^{2} \)

Calculating further :

\(\longrightarrow \quad \: Area_ { (Circle)} = \pi \times \dfrac{7}{2} \times \dfrac{7}{2} \)

After multiplication of 7/2 with 7/2 we get :

\(\longrightarrow \quad \: Area_ { (Circle)} = \pi \times \dfrac{49}{4} \)

On dividing 49 by 4 we get :

\(\longrightarrow \quad \: \blue{{\boxed{\frak{Area_ { (Circle)} = 12.25\pi \: inches {}^{2} }}}}\)

Remember one thing , we haven't put value of π as 22/7 or 3.14 because in the question it is given that we have to find the area of circle in terms of pi .
