The area of a circle with radius r is given by A = π r2. Find the area of a circle with radius 7 centimeters. Use 3.14 for π..

Answers

Answer 1

Step-by-step explanation:

Hey there!

Given;

Radius of a circle (r) = 7cm

Now;

We know that;

Area of circle (a) = π*(r^2)

= 3.14*(7^2)

= 3.14*49

= 153.86 cm^2

Therefore, the area of a circle is 153.86 cm^2.

Hope it helps...

An estate of ​$485,000 is left to three siblings. The eldest receives 3 times as much as the youngest. The middle sibling receives ​$13,000 more than the youngest. How much did each​ receive?

Answers

Answer:

Step-by-step explanation:

the youngest received 94,200

the middle received 107,200

the eldest received 283,600

Step-by-step explanation:

Given parameters:

Worth of the estate  = $485000

Unknown:

Amount received by each sibling = ?

Solution:

Let the amount received the eldest  = e

                                                 middle  = m

                                                 youngest  = y

                  e  = 3y

                 m = y + 13000

so;

      e + m + y  = 485000

      3y + y + 13000 + y  = 485000

         5y  = 485000 - 13000

         5y  = 472000

           y  = $94400

Eldest  = 3y  = 3 x 94400 = $283200

Middle  = $94400 + $13000 = $107400

Youngest  = $94400

The coordinates of both the pre-image and image of quadrilateral JKLM are listed in the table
below.
Which rule best represents this dilation?
A- (x, y) -> (4/11 x, 4/11 y)
B- (x,y) -> (3/22 x, 3/22 y)
C- (x, y) -> (11/4 x, 11/4 y)
D- (x, y) -> (22/3 x, 22/3 y )

Answers

Answer:

Option C.

Step-by-step explanation:

From the table attached,

Pre-image coordinates J(-8, 2) → Image coordinates J'(-22, 5.5)

J(-8, 2) → J'(-22, 5.5)

Since, rule for the dilation of a point is,

(x, y) → (kx, ky) [Here k = scale factor of dilation]

Therefore, kx = -22

k(-8) = -22

k = [tex]\frac{-22}{-8}[/tex]

k = 2.75

So the scale factor should be 2.75

From the given options,

Option A.

(x, y) → [tex]\frac{4}{11}(x, y)[/tex]

       → 0.36(x, y)

But value of k should be 0.36

Therefore, Incorrect option.

Option B.

(x, y) → [tex]\frac{3}{22}(x, y)[/tex]

       → 0.14(x, y)

k = 0.14

But the value of k should be 2.75

Incorrect option.

Option C.

(x, y) → [tex]\frac{11}{4}(x, y)[/tex]

       → 2.75(x, y)

k = 2.75

Therefore, this option is correct.

Option D.

(x, y) → [tex]\frac{22}{3}(x, y)[/tex]

       → 7.33(x, y)

k = 7.33

But the scale factor should be 7.33

Incorrect option.

How long will it take for an investment to triple, if interest is compounded continuously at 8%?
It will take years before the investment triples.

Answers

Answer:

It will take 14 years before the investment triples

Step-by-step explanation:

Continuous Compounding

Is the mathematical limit that compound interest can reach if it was calculated and reinvested into an account's balance over a theoretically infinite number of periods.

The formula for continuous compounding is derived from the formula for the future value of a compound interest investment:

[tex]FV = PV\cdot e^{i.t}[/tex]

Where:

FV = Future value of the investment

PV = Present value of the investment

i     = Interest rate

t     = Time

It's required to find the time for an investment to triple, that is, FV = 3 PV, knowing the interest rate is i=8%=0.08.

Substituting the known values:

[tex]3PV = PV\cdot e^{i.t}[/tex]

Dividing by PV:

[tex]3 = e^{i.t}[/tex]

Taking logarithms:

[tex]\ln 3=i.t[/tex]

Solving for t:

[tex]\displaystyle t=\frac{\ln 3}{i}[/tex]

[tex]\displaystyle t=\frac{\ln 3}{0.08}[/tex]

t = 13.7 years

Rounding up:

It will take 14 years before the investment triples

It will take 37.5 years before the investment triples.

The formula for calculating the future value is expressed as:

[tex]A =Pe^{rt}[/tex]

P is the principal

r is the rate (in %)

t is the time (in years)

If the investment tripled, then A = 3P. The equation will become:

[tex]3P=Pe^{rt}\\3=e^{rt}\\ln3 =lne^{rt}\\rt = 3\\0.08t =3\\t =\frac{3}{0.08} \\t =37.5 years[/tex]

Hence it will take 37.5 years before the investment triples.

If ABCD is a parallelogram. BC=13 and AB=5, what is the perimeter of the parallelogram?

Answers

Answer:

36

Step-by-step explanation:

In a Parallelogram , it is important to note that opposite sides are equal to each other.

We are given parallelogram ABCD.

We have sides: AB, BC, CD, AD.

Since opposite sides are equal then:

AB = CD

BC = AD

The perimeter of a parallelogram is the sum of all its sides.

In the question: BC=13 and AB=5

Hence,

AB = CD = 5

BC = AD = 13

Perimeter of Parallelogram ABCD = 5 + 5 + 13 + 13

= 36.
