7. The population of Flood River City is now 42,000. Experts predict the population will decrease 25% each

year for the next five years. What will be the population in five years?

Answers

Answer: The population after five years = 9967

Step-by-step explanation:

The exponential equation for population decay : [tex]P=A (1-r)^t[/tex], where A = initial population r= rate of decay , t= time

Given: A= 42000, r= 25%= 0.25, t= 5

then

[tex]P=42000(1-0.25)^5\\\\=42000(0.75)^5\\\\=42000(0.2373046875)\\\\\approx9967[/tex]

Hence, The population after five years = 9967

drawing a vowel from letter tiles that spell out MATHEMATICS
chance
Blank 1:
Blank 2:

Answers

Answer:

3/ 8 ; 3/8

Step-by-step explanation:

MATHEMATICS

vowels in mathematics = (A, E, I)

letters in mathematics = (M, A, T, H, E, I, C, S)

Probability = required outcome / Total possible outcomes

Required outcome = vowels in mathematics = 3

Total possible outcomes = letters in mathematics = 8

Probability of drawing a vowel letter tiles = 3/8

2.)

Spinner division :

Red = 4 ; white =2 ; green = 1 ; blue = 1

Total divisions = 8

Probability (landing on blue) = number of blue / total

P(landing on blue) = 1 / 8

P(landing on white) = 2/ 8 = 1/4

P(landing on blue or white) = 1/8 + 2/8 = 3/8

In a right triangle one angle measure 28° more than the other acute angle. Use equations to solve for the measures of the two unknown angles.

Answers

Answer:

One acute angle is 31 degrees and the other acute angle is ( 31+28=) 59 degrees.

Step-by-step explanation:

In the right angled triangle one angle is always equal to 90 degrees.

Suppose <a= 90 degrees

< b= x degrees

< c= x+28 degrees

The sum of all the angles of the triangle are always equal to 180 degrees

therefore

<a+ <b+<c= 90 + x+ x+28 = 180

2x= 180- 28- 90

2x=62

x= 31 degrees

One acute angle is 31 degrees and the other acute angle is ( 31+28=) 59 degrees.

An acute angle is an angle which has less than 90 degrees in measurement .

Hence both angles of the right angle triangle are acute angles , 31 and 59 degrees.

find the size of x and y
this is a figure of parallelogram

Answers

Answer:

x = 75° , y = 105°

Step-by-step explanation:

Opposite angles in a parallelogram are equal , then

x = 75°

Consecutive angles in a parallelogram are supplementary, sum to 180° , so

x + y = 180° , that is

75° + y = 180° ( subtract 75° from both sides )

y = 105°

Incase you can’t see the picture, it says “Explain how to solve the following equation and check for extraneous solutions: x= square root of -2x+6 then out of square root +3 Please help guys

Answers

Answer:

x=3

Step-by-step explanation: too much math to put here

Answer:

x= 3 ; (x=1 is an extraneous solution)

Step-by-step explanation:

-2x+6 is under a square root, so its value must be > or equal to 0

If we solve the inequality

-2x+6 ≥ 0 we obtain

-x+3≥ 0

-x ≥ -3

x ≤ 3

now that we know the possible values of x we can proceed like this:

1) move 3 on the left side of equal and change its sign

x-3 = √-2x+6

2) square the two members of the equation

x^2 + 9 -6x = -2x+6

3) solve the equation

x^2 -4x +3 = 0

(x-3)(x-1) = 0

x = 3

x = 1

4) Check if the solution are ≤ 3 and if they make true the equation

Both solutions are ≤ 3

if x = 3

3 = √-6+6 + 3

3 = 3

true

x=1

1 = √-2+6 + 3

1 = 2+3

1 = 5 false

In conclusion we can say the 3 is a real solution, while 1 is an extraneous solution

When you borrow money to buy a house, a car, or for some other purpose, you repay the loan by making periodic payments over a certain period of time. Of course, the lending company will charge interest on the loan. Every periodic payment consists of the interest on the loan and the payment toward the principal amount. To be specific, suppose that you borrow $1,000 at an interest rate of 7.2% per year and the payments are monthly. Suppose that your monthly payment is $25. Now, the interest is 7.2% per year and the payments are monthly, so the interest rate per month is 7.2 / 12 5 0.6%. The first months interest on $1,000 is 1000 3 0.006 5 6. Because the payment is $25 and the interest for the first month is $6, the payment toward the principal amount is 25 2 6 5 19. This means after making the first payment, the loan amount is 1, 000 2 19 5 981. For the second payment, the interest is calculated on $981. So the interest for the second month is 981 3 0.006 5 5.886, that is, approximately $5.89. This implies that the payment toward the principal is 25 2 5.89 5 19.11 and the remain- ing balance after the second payment is 981 2 19.11 5 961.89. This process is repeated until the loan is paid. Write a program that accepts as input the loan amount, the interest rate per year, and the monthly payment. (Enter the interest rate as a percentage. For example, if the interest rate is 7.2% per year, then enter 7.2.) The program then out- puts the number of months it would take to repay the loan. (Note that if the monthly payment is less than the first months interest, then after each payment, the loan amount will increase. In this case, the program must warn the borrower that the monthly payment is too low, and with this monthly payment, the loan amount could not be repaid.)28. (Apartment problem) A real estate office handles, say, 50 apartment units. When the rent is, say, $600 per month, all the units are occupied.

How many units should be rented to maximize the profit?Write a program that prompts the user to enter:a. The total number of units.b. The rent to occupy all the units.c. The increase in rent that results in a vacant unit.d. Amount to maintain a rented unit.The program then outputs the number of units to be rented to maximize the profit.30. Let n be an integer. The value of the expression lim (1 1 1 ) is n` n written as e. This number e appears in many places in mathematics. For example, it appears in the formula A 5 Pert to compute the total mount accumulated when the interest is compounded continuously. It also appears in problems relating to exponential growth and decay. It is known that e is an irrational number. The value of e to nine decimal places is e 5 2.718281827. Write a program that computes the value n of the expression lim (1 1 1 ) between certain values of n and then n` n compare the values with e. For example, you can compute the values of the expression between 100 and 10,000 with an increment of 100, or between 1,000 and 1,000,000 with an increment of 1,000.
