Answer:add 5 to both sides

Step-by-step explanation:

The area of the given figure is 25cm².

Area of rectangle

Area = length x width

Perimeter of rectangle

Perimeter = length + length + width + width

Hence, we have

length = 5cm

width = 5cm

then, by applying the Area of the rectangle, we get

Area = length x width

Area = 5 x 5

      = 25cm²

Hence, The area of the given figure is 25cm².

Step-by-step explanation:

Two cards are drawn randomly from a well-shuffled deck of cards without replacement. Find the probability of getting both face cards in succession.

In a deck of 52 cards, there are three face cards (J, Q, and K) in each of four suits (clubs, diamonds, hearts, and spades). That means there are 12 face cards in total (J♣, Q♣, K♣, J♦, Q♦, K♦, J♥, Q♥, K♥, J♠, Q♠, K♠).

The probability of drawing a face card the first time, then, is 12 out of 52.

There is now one less face card in the deck, as well as one less card in the deck. Therefore, the probability of drawing a face card a second time is 11 out of 51.

The probability, then, of drawing two face cards in succession is:

[tex]\frac{12}{52}\times{\frac{11}{51}}=\frac{132}{2652}=\frac{11}{221}\approx{0.0498}\approx{4.98\%}[/tex]

The percent of change each year is 15%.

How to calculate percentage?

A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The proportion therefore refers to a component per hundred. Per 100 is what the word percent means. The letter "%" stands for it.

It is given that The number of carbon atoms in a fossil is given by the function y = [tex]51000(0.85)^t[/tex], where t represents the number of years since being discovered.

Here , y  =  [tex]51000(0.85)^t[/tex]

t = number of years

y = number of carbon atoms in a fossil.

For t = 1 year

y = 51000[tex](0.85)^1= 51000(0.85) = 43350[/tex]

For t = 2 years

y = 51000[tex](0.85)^2= 36847.5[/tex]

For t = 3 years

y = 51000[tex](0.85)^3=31320.375[/tex]

Percentage change in one year = [tex]\frac{36847.5-43350}{43350}[/tex] × 100 = -15%

Percentage change in second year =  [tex]\frac{31320.375-36847.5}{36847.5}[/tex] × 100 = -15%

here, negative sign shows decrement. In this way, every year carbon atom in fossil decreases by 15%.

Therefore, the percent of change each year is 15%.

The magnitude of the boats resultant vector is 314.1 mi

A vector is a physical quantity that has both magnitude and direction.

A resultant vector is the sum of two or more vectors.

Since the boat sails 285 miles south and then 132 miles west, we have that its first direction vector is r = (285 mi)j. Also, its direction vector west is r' = -(132 mi)i

So, the resultant vector R = r + r'

=  (285 mi)j + (132 mi)i

=  (132 mi)i + (285 mi)j

So, the magnitude of the resultant vector is R = √(r² + r'²)

So, substituting thevalues of the variables into the equation, we have

R = √(r² + r'²)

R = √((285 mi)² + (132 mi)²)

R = √(81225 mi² + 17424 mi²)

R = √(98649 mi²)

R = 314.08 mi

R ≅ 314.1 mi

So, the resultant vector is 314.1 mi

The value of the algebraic expression is:

a^2*b = -15 + 20i

Here we have the following expression:

a^2*b

And we want to use the values:

a = -1 + 2i

b = 5

Replacing these values in the expression we will get:

(-1 + 2i)^2*5

Expanding the  first part we get:

(-1 + 2i)*(-1 + 2i) = (-1)*(-1) + (-1)*(2i) + (2i)*(-1) + (2i)*(2i)

                        = 1 - 2i - 2i - 4

                        = -3 + 4i

From the information, the following can be deduced:

Refrigerator = $595

Discount = 20%

Tax = 9.25%

The sales price will be:

= Refrigerator price + Tax - Discount

= $595 + (9.25% × $595) - (20% × 650)

From the question. the expression is given as

(2/3)²

We start by rewriting the expression using repeated multiplication

This in other words means that:

We rewrite the (2/3)² as repeated multiplication

To do this, we apply the exponent rule of indices

This rule states that:

a^m = a * a * a .... in m places

So, we have

(2/3)² = (2/3) x (2/3)

Evaluate the products

(2/3)² = 4/9

The quadratic function whose only zero is -13 is h(x) = x² + 26x + 169

From the question, we are to write a quadratic function whole only zero is -13.

Since -13 is the only zero of the function,

Then,

x = -13 twice

This means that (x + 13) is a factor of the function

Since x = -13 twice,

Then,

The quadratic function h is

h(x) = (x + 13)(x + 13)

Expand the quadratic function by distributing

h(x) = x(x + 13) + 13(x + 13)

h(x) = x² + 13x + 13x + 169

The price that yields maximum revenue is equal to $99. Also, the maximum revenue is equal to $490,050.

In order to determine the price that would yield the maximum revenue, we have to find the derivative of the revenue function R(p) by applying the Power Rule.

Mathematically, the revenue function, R(p) is given by this mathematical expression:

Revenue function, R(p) = NP

Where:

Let the variable n represent the number of reductions in the price. Therefore, we have:

N = 3,400 + 50n    ....equation 1.

P = 130 - n

n = 130 - P

From equation 1, we have:

N = 3,400 + 50(130 - P)

N = 3,400 + 6,500 - 50P

Next, we would re-write the revenue function R(p) as follows:

Revenue function, R(p) = (3,400 + 6,500 - 50P)P

Revenue function, R(p) = 3,400P + 6,500P - 50P²

Revenue function, R(p) = 9,900P - 50P²

Taking the derivative of R(p), we have:

R'(p) = 9,900 - 100P

100P = 9,900

Price, P = 9,900/100

Price, P = $99

For the the maximum revenue, we have:

Maximum revenue, R(p) = 9,900P - 50P²

Maximum revenue, R(p) = 9,900(99) - 50(99)²

Maximum revenue, R(p) = 980,100 - 490,050

Maximum revenue, R(p) = $490,050.

Define interest.

When you borrow money, you must pay interest, and when you lend money, you must charge interest. The most common way to represent interest is as a percentage of a loan's total amount per year. The loan's interest rate is denoted by this proportion.

Solution Explained:

First, let's calculate the amount after adding the compound interest using

[tex]A = P(1 + \frac{r}{n})^{nt}[/tex], where P is principal, r = interest rate, n = number of times interest is compounded monthly, and t = time

After calculation (For Op 1 and 2, the principal is $9000 and 3 is $1000)

Option 2 has $17467
Option 3 has $6489.17

The standard deviation of the binomial distribution is of:
