The area of the given parallelogram is 12 cm².

A parallelogram is defined as a special type of quadrilateral that has both pairs of opposite sides parallel and equal.

The formula to calculate the area of a parallelogram can thus be given as,

Area of parallelogram = b × h square units

where b is the length of the base and h is the height

According to the given parallelogram ABCD, we have

Length of the base b = 5 + 9 = 14 cm

The height h = 8 cm

Area of parallelogram = b × h

Area of parallelogram = 14 × 8

Area of parallelogram = 112 cm²

Thus, the area of the given parallelogram is 12 cm².

It is important to understand the concept of interest beacause it is a part of our life and it hels us to understand the economic situation of ourselves.

It is the interest calculated on the principal at a given rate for a time period.

We have.

There are two types of interest commonly studied.

1)

Simple interest

2)

Compound interest

Now,

Simple interest is the interest calculated only on the principal year after year.

Whereas compound interest is the interest calculated on the principal as well as the interest after the first year.

Example:

Principal = $100

Rate = 10%

Time = 2 years

Simple interest after two years.

= 2 x (10% of 100)

= 2 x (1/10 x 100)

= 2 x 10

= $20

Compound interest after two years.

Ist year:

=  (10% of 100)

= (1/10 x 100)

= $10

2nd year:

= 10% of (100 + 10)

= 1/10 x 110

= $11

So,

= 10 + 11

= $21

Thus,

In right triangle ABC, the value of x is equal to 0.06.

In Mathematics, a right angle can be defined as a type of angle that is formed in a triangle by the intersection of two (2) straight lines at 90 degrees. This ultimately implies that, a right angled triangle has a measure of 90 degrees.

Since the angle formed by side A is a right triangle, we have the following complementary angles;

C + B = 90

sin(C) = cos(B)

The mean number of domestic applicants that Jenny selects is exactly 9.5, and the standard deviation is approximately 1.932

Standard deviation is defined as the amount of variation or the deviation of the numbers from each other.

This is a problem involving a hypergeometric distribution since we have a fixed population (all applicants), two groups within the population (domestic and international students), and a fixed number of samples (20 students to be admitted).

Let X be the number of domestic applicants that Jenny selects this year. Then X follows a hypergeometric distribution with parameters N = 80 (total number of applicants), K = 38 (number of domestic applicants), and n = 20 (number of students to be admitted).

The mean of X is given by μ = nK/N, and the standard deviation of X is given by,

σ = √(nK(N-K)/(N²(N-1))).

Substituting the given values, we get:

μ = (20 x 38)/80 = 9.5

σ = √(203842/(80² x 79)) ≈ 1.932

Therefore, the mean number of domestic applicants that Jenny selects is exactly 9.5, and the standard deviation is approximately 1.932.

The expression for its distance d (measured in feet) from the intersection t seconds later is d = x + 79200 t (feet)

Since the balloon is moving due east, we only need to consider its horizontal motion, ignoring its vertical motion at a constant altitude of 95 feet.

Let's call the initial distance of the balloon from the intersection x. The distance of the balloon from the intersection t seconds later can be found using the formula for distance traveled at a constant speed:

d = x + vt

where v is the speed of the balloon (15 miles per hour) and t is the time elapsed (in hours). To convert the speed from miles per hour to feet per second, we can multiply by the conversion factor of 5280 feet per mile:

d = x + (15 miles/hour) * (5280 feet/mile) * (t hours)

d = x + (15 * 5280) t feet

d = x + 79200 t feet

So the expression for the distance of the balloon from the intersection t seconds later is:

d = x + 79200 t (feet)

What is area of square ?

Area of square can be defined as the square of given side.

Given ,

Let's assume that the side length of the original square is 's'. The perimeter of the original square is then 4s and its area is s².

The perimeter of the dilated square will be 4 times longer than the original square, so it will be 4 * 4s = 16s.

The area of the dilated square will be 4 times greater than the original square, so it will be 4^2 * s² = 16s².

Here s is 12

so ,

16s = 16 * 12 = 192

16s*s = 16 * 12 * 12 = 2304

Step-by-step explanation:

Given polynomial:

[tex]f(x)=-3x^3-5x^2+x-7[/tex]

If P(x) is a polynomial with integer coefficients and if p/q is a root of P(x), then p is a factor of the constant term of P(x) and q is a factor of the leading coefficient of P(x).

Possible p-values

Factors of the constant term:  ±1, ±7

Possible q-values

Factors of the leading coefficient:  ±1, ±3

Therefore, all the possible values of p/q:

[tex]\sf \dfrac{p}{q}=\dfrac{\pm1}{\pm1},\dfrac{\pm1}{\pm3},\dfrac{\pm7}{\pm1},\dfrac{\pm7}{\pm3}=\pm 1, \dfrac{\pm1}{\pm3},\pm 7, \dfrac{\pm7}{\pm3}[/tex]

Substitute each possible rational root into the function:

Answer:

To find the time it takes a car traveling at 40 mph to stop after covering a distance of 30 feet, we need to use the formula for distance, speed, and time, which is:

distance = speed * time

Rearranging the formula, we get:

time = distance / speed

Since the speed is in miles per hour (mph), we need to convert it to feet per second (fps). One mph is equivalent to 1.47 fps, so 40 mph is equivalent to 40 * 1.47 = 58.8 fps.

Now we can plug in the values for distance and speed into the formula:

time = 30 feet / 58.8 fps

time = 0.5104 seconds

Rounding to the nearest second, we get:

time = 0.51 seconds

So, it would take the car approximately 0.51 seconds to stop after traveling 40 mph.

What are expressions exactly?

In mathematics, expressions are mathematical claims that consist of at least two sentences that contain numbers, variables, or both, and are linked by an operator in between. Mathematical operations include addition, subtraction, multiplication, and division. For instance, x + y is an equation in which the words x and y are separated by an addition operator. In mathematics, there are two types of expressions: numerical expressions, which include only numbers, and algebraic expressions, which contain both numbers and variables.

e.g. A number is 6 more than half of another number, x. This proposition can be stated mathematically as x/2 + 6. Mathematical expressions are used to answer complex problems.

Now,

Given that Total campers = 2375

and for each cabin there are 2 counselors and 50 campers

then no. of cabins = 2375/50

No. of counselors= 2*no. of cabins

=2*2375/50

So, the fair market value of her Roth IRA at age 65 is $29,706.74.

The amount of interest earned can be calculated as follows:

Future value: $29,706.74 Present value: $2,500 Interest earned: $29,706.74 - $2,500 = $27,206.74

So, the interest rate for the GNMA Mortgage issue bond is 9.375%, rounded to the nearest hundredth of a percent.

6. Let's call the number of days that Ricardo has to pay back the loan "d".

The interest on the loan can be calculated using the formula:

I = P * r * t

where I is the interest, P is the principal (the amount borrowed, $2,500), r is the annual interest rate as a decimal (7.8% as a decimal is 0.078), and t is the time in years (d divided by 365).

So we have:

I = $2,500 * 0.078 * (d / 365)

We also know that the maturity value of the loan is the sum of the principal and the interest:

$2,548.75 = $2,500 + I

So we can substitute for I:

$2,548.75 = $2,500 + $2,500 * 0.078 * (d / 365)

Expanding the right-hand side:

$2,548.75 = $2,500 + $194.00 * (d / 365)

And solving for d:

d = 365 * ($2,548.75 - $2,500) / $194.00

d = 365 * ($48.75) / $194.00

d = 365 * 0.25191780821917808

d = 91.37 days

So Ricardo would have to pay back the loan in 91.37 days.

Answer:

Step-by-step explanation:

We can use the formula for the future value of an annuity to find the amount you'll have in the account at the end of Year 6. An annuity is a series of equal payments made at equal intervals of time, and the future value of an annuity is the amount you'll have in the future if you invest those payments and earn a given rate of interest.

The formula for the future value of an annuity is:

FV = PMT * (((1 + r)^n - 1) / r)

where:

FV = future value of the annuity

PMT = annual payment amount

r = annual interest rate as a decimal

n = number of payments

In this case:

PMT = $1,500

r = 0.05

n = 6

Plugging in the values:

FV = $1,500 * (((1 + 0.05)^6 - 1) / 0.05)

FV = $1,500 * (1.328867 - 1) / 0.05

FV = $1,500 * 0.328867 / 0.05

FV = $1,500 * 6.577340

FV = $9,865.61

So, the amount in the account at the end of Year 6 will be $9,865.61. To find the last payment, we subtract this amount from the desired future value of $10,000:

$10,000 - $9,865.61 = $134.39

Therefore, your last payment will be $134.39.
