The circular opening of a vase has an inside diameter of 13.5 cm.

-13.5 c

What is the approximate area of this circular opening? (Use a = 3.14.)

Answer:

the answer is the answer the answer is x=55 degrees because the angle sum for a triangle is 180 degrees and because we are told angle A and angle C are congruent that means you can simply take 180 - 70 to get 110 and i simply divided that by 2 and got 55 degrees

Answer:

Juan travel 31.4 feet farther than Fred in one rotation.

Step-by-step explanation:

In this problem we need to determine the change in linear position of Fred and Juan, whose formula is:

[tex]s=\theta \cdot r[/tex] (Eq. 1)

Where:

[tex]r[/tex] - Radius, measured in feet.

[tex]\theta[/tex] - Angular arch, measured in radians.

[tex]s[/tex] - Change in linear position, measured in feet.

If both makes one rotation in the carousel, we obtain the change in linear position of each player:

Fred ([tex]r = 7\,ft[/tex], [tex]\theta = 2\pi[/tex])

[tex]s= 2\pi\cdot (7\,ft)[/tex]

[tex]s = (3.14)\cdot (7\,ft)[/tex]

[tex]s = 21.98\,ft[/tex]

Juan ([tex]r = 17\,ft[/tex], [tex]\theta = 2\pi[/tex])

[tex]s= 2\pi\cdot (17\,ft)[/tex]

[tex]s = (3.14)\cdot (17\,ft)[/tex]

[tex]s = 53.38\,ft[/tex]

And the difference between both travelled distances is:

[tex]\Delta s = 53.38\,ft-21.98\,ft[/tex]

[tex]\Delta s = 31.4\,ft[/tex]

Juan travel 31.4 feet farther than Fred in one rotation.

The initial value of the investment in the given function is 1500.

Interest on interest, or compound interest, is the adding of interest to the principal sum of a loan or deposit. It's the outcome of reinvesting interest rather than paying it out so that interest is received on the principal plus previously collected interest in the next quarter.,

[tex]A = P(1+ \dfrac{r}{n})^{nt}[/tex]

where A is the final amount

P is the principal amount

r is the rate of interest

n is the number of times interest is charged in a year

t is the number of years

Given that the future value, [tex]F(t) = 1,500(1.045)^t,[/tex] of an investment after t years is given by the function defined above. Therefore, the initial value of the investment in the given function is 1500.

Step-by-step explanation:

The data collected while examining the species of butterflies present in a particular area which are represented using Latin names is a non-numeric data type is aimed at separating or making distinction among the species available. These types of data used in classification are called Qualitative variables.

Also, the data is nominal and not ordinal, this is because there is no sort of order or ranking in the groups or species names. Qualitative variables in which does not posses ordering or ranking in the categories are represented on the nominal scale. Whose which implies order or rank are represented on the ordinal scale.

The function [tex]p(n)[/tex] is represented by [tex]p(n) = 103\cdot (0.88)^{n}[/tex].

Step-by-step explanation:

Statement indicates that atmospheric pressure decreases exponentially when height above sea level is increased. This fact is represented by the following model:

[tex]p(n) = p_{o}\cdot r^{n}[/tex] (Eq. 1)

Where:

[tex]p_{o}[/tex] - Atmospheric pressure at sea level, measured in kilopascals.

[tex]r[/tex] -Atmospheric pressure decrease rate, dimensionless.

[tex]n[/tex] - Height above sea level, measured in kilometers.

[tex]p(n)[/tex] - Current pressure, measured in kilopascals.

If we know that [tex]p_{o} = 103\,kPa[/tex] and [tex]r = 0.88[/tex], the function [tex]p(n)[/tex] is represented by:

[tex]p(n) = 103\cdot (0.88)^{n}[/tex]

Answer: 125

In Kennington, 25 legislators represent 500,000 people.

Find how many times 500,000 go into 2,500,000 people.

2,500,000 ÷ 500,000 = 5

Now, multiply 5 by 25, because each 500,000 people are represented by 25 legislators.

25 x 5 = 125.

Answer = 125.

The percentage increase for flight tickets to fly from orlando to hartford would be = 67.5% and 92.5% when there is an additional $50 to the new price.

Percentage increase is defined as the rise in the quantity or amount for an object which is converted into percentage.

The formula for percentage increase would be = increase ÷ original amount × 100

The increase of the cost = 335 - 200 = $135

The original amount = $200

The percentage increase = 135/200 × 100

= 13500/200 = 67.5%

But if the increase in cost is 135 + 50 = $185

The percentage increase of the new cost would be;

= 185/200 ×100

= 18500/200

= 92.5%

The actual area of the field in square kilometers is [tex]30000000 km^2[/tex]

Step-by-step explanation:

Scale : 1 cm = 50000 km

Area of field on map = [tex]1.2 cm^2[/tex]

Now , 1 cm = 5000 km

[tex]1 cm^2 = (5000 km)^2[/tex]

We are supposed to find the actual area of the field in square kilometers.

So, the actual area of the field in sq. km =[tex]1.2 \times (5000)^2[/tex]

Actual area of the field in sq. km [tex]=30000000 km^2[/tex]

Hence the actual area of the field in square kilometers is [tex]30000000 km^2[/tex]

Use the quotient rule:

[tex]\dfrac{\mathrm dy}{\mathrm dx}=\dfrac{(2x+4)(x^3-5)-3x^2(x^2-4x)}{(x^3-5)^2}[/tex]

Answer:

The coordinates of endpoint S are [tex]S(x,y) = (8,-18)[/tex].

Step-by-step explanation:

Let [tex]T(x, y) = (0, 6)[/tex] and [tex]M(x,y) = (4,-6)[/tex], which is the midpoint of line segment ST. From Linear Algebra we get that midpoint is the following vector sum of endpoints S and T. That is:

[tex]M(x,y) = \frac{1}{2}\cdot S(x,y) + \frac{1}{2}\cdot T(x,y)[/tex] (Eq. 1)

Now clear S in the previous expression:

[tex]S(x,y) = 2\cdot M(x,y) - T(x,y)[/tex] (Eq. 1b)

Then, the coordinates of point S are:

[tex]S(x,y) = 2\cdot (4,-6) - (0,6)[/tex]

[tex]S(x,y) = (8, -18)[/tex]

The coordinates of endpoint S are [tex]S(x,y) = (8,-18)[/tex].
