Answer:

d

Step-by-step explanation:

The true statement: A The two functions have the same initial value.

A linear function has a straight line as its graph.

A linear function has the form shown below.

a + bx = y = f (x).

A linear function consists of one independent variable and one dependent variable. The independent and dependent variables are x and y, respectively.

We know that function E is a linear function with an initial value of 2 and a rate of change of 1/3. Therefore, the equation for function E can be written as:

E(x) = (1/3)x + 2

We also know that function F is a linear function that includes the points (2, 8) and (0, 2).

We can use the two points to find the slope of the line and then use the point-slope form to write the equation for function F.

The slope of F = (8 - 2) / (2 - 0) = 6/2 = 3

Using point-slope form with the point (2, 8), we get:

F(x) - 8 = 3(x - 2)

F(x) = 3x + 2

Now we can compare the two functions.

A. The initial value of function E is 2, while the initial value of function F is 2 + 3(0) = 2. Therefore, statement A is true.

B. The rate of change of function E is 1/3, while the rate of change of function F is 3. Therefore, statement B is false.

C. The initial value of function F is 2, which is the same as the initial value of function E. Therefore, statement C is false.

D. The rate of change of function E is 1/3, which is less than the rate of change of function F, which is 3. Therefore, statement D is false.

Therefore, the only true statement is A. The two functions have the same initial value.

Answer:

Jada’s neighbor is 16 years of age

Step-by-step explanation:

In this question, we are interested in calculating the age of Jada’s neighbor, given the information in the question.

Let the present age of the neighbor be x years

Her age in 4 years will be x + 4 years old

Her age 4 years ago was x -4 years old

Now, the difference between twice her age in 4 years minus twice her age 4 years ago is her present age.

mathematically that means;

2(x+ 4) - 2(x -4 ) = x

2x + 8 - 2x +8 = x

16-0 = x

x = 16 years

1.If consumer income increases and worker wages fall, quantity will rise, and prices will fall. TRUE. If consumer income increases, people will have more purchasing power and they will be able to buy more tangerines.

On the other hand, if the wages of workers fall, it will result in lower production costs for tangerines and the producers will sell them at a lower price which will eventually result in higher demand and therefore, the quantity will rise and prices will fall. 2. If orange prices decrease and taxes on citrus fruits decrease, quantity will fall, and prices will rise.FALSE. If orange prices decrease, it means that the demand for tangerines will fall since people will prefer to buy oranges instead of tangerines. Therefore, the quantity will fall and the prices will rise due to lower supply.So, the statement is false.

3. If the price of canning machinery (a complement) increases and the growing season is unusually cold, quantity and price will both fall. UNCERTAIN. Canning machinery is a complementary good which means that its price is directly related to the price of tangerines. If the price of canning machinery increases, the cost of production of tangerines will also increase. This will lead to a decrease in supply and thus, prices will increase. However, if the growing season is unusually cold, it will result in lower production of tangerines which will lead to lower supply and hence higher prices. Therefore, it is uncertain whether the quantity and price will both fall.

Answer:

There are 11 pigs and 17 chickens.

Step-by-step explanation:

Lets let

p = number of pigs

c = number of chickens

Assuming each animal has only one head, then

p + c = 28

And assuming that pigs have four feet and chickens have two feet:

pig feet = 4p

that is, 4 feet for each pig, and



chicken feet = 2c

right? two feet per chicken.



All the feet are:

4p + 2c = 78

Now we have two equations and two unknowns, so we can solve this "system of equations". You can use substitution or elimination method (or even graphing or matrices) I will run through elimination method.

Multiply p+c=28 times -2.

-2p + -2c = -56

then add the whole equation to the other equation. Do this adding vertically, from top to bottom.

-2p + -2c = -56

4p + 2c = 78

_____________

2p = 22

Divide by 2 to solve

p = 11

There are 11 pigs.

Remember,

p + c = 28

11 + c = 28

subtract 11

c = 17

There are 17 chickens.

The simple interest rate on the account is 13%

Here Sunil deposited $400 for one and a half years, and the interest he gets is $78. He deposits in at the simple rate of interest.

We know that the simple interest formula is

     Simple interest = Principle × time × rate/ 100

It is given that,

            simple interest = $78

            time = 1 \(\frac{1}{2}\) year = 3/2 year

            Principle = $400

Let the rate of interest be r

So we have

     78 =( 400 × 3/2 × r )/100

     r =( 78 × 2×100) / (400 × 3)

     r = 39%

Therefore the simple interest rate on the account is 13%.

Answer:

y = -3

Step-by-step explanation:

Add 2 to each side to isolate the -3y. Doing this leaves you with -3y=9. You then divide each side leaving you with y = -3

Answer:

The equation has one solution at which y = -3.

Step-by-step explanation:

To find the value of y, we need to isolate it from the rest of the equation.

\(\displaystyle{-3y-2=7}\\\\-3y = 9\\\\\bold{y = -3}\)

We can check to make sure that y = -3 by substitution.

\(\displaystyle{-3(-3)-2 = 7}\\\\9-2=7\\\\7= 7 \ \checkmark\)

Because we got a true statement, we can determine that y = -3.

Half of the time, the coin will land on heads and the cube will land on an even number when Patty tosses the coin and rolls the number cube 60 times.

The binomial probabilities is the experimental probability in which the total number of output values is 2, therefore it is known as binomial probabilities.

The number of independence variable in case of binomial experiments is fixed. Both the two output has the 1/2 chances to occur.

Patty tosses the coin and rolls the number cube 60 times.

For the coin, there are total 120 outcomes for 60 tosses, in which 60 favorable outcomes to land on heads. Thus, the probability the coin will land on heads is,

\(P=\dfrac{60}{120}\\P=\dfrac{1}{2}\)

For the number cube, there are total 360 outcomes (6×60) for 60 rolls, in which 180 favorable outcomes (3×60) to land on even number. Thus, the probability the number cube will land on even number is,

\(P=\dfrac{180}{360}\\P=\dfrac{1}{2}\)

tan 36° can be written as cot 54°, which simplifies to (√3 + 1) / (√3 - 1).

The tangent of 36° can be expressed in terms of its cofunction, which is the cotangent. The cotangent of an angle is equal to the reciprocal of the tangent of that angle. Therefore, we can rewrite tan 36° as cot (90° - 36°).

Now, cot (90° - 36°) can be simplified further. The angle 90° - 36° is equal to 54°. So, we have cot 54°.

The cotangent of 54° can be determined using the unit circle or trigonometric identities. In this case, the exact answer for cot 54° is (√3 + 1) / (√3 - 1).

Answer:

y = \(\frac{1}{2}\) x - 4

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - 2x + 8 ← is in slope- intercept form

with slope m = - 2

Given a line with slope m then the slope of a line perpendicular to it is

\(m_{perpendicular}\) = - \(\frac{1}{m}\) = - \(\frac{1}{-2}\) = \(\frac{1}{2}\) , then

y = \(\frac{1}{2}\) x + c ← is the partial equation

To find c substitute (6, - 1 ) into the partial equation

- 1 = 3 + c ⇒ c = - 1 - 3 = - 4

y = \(\frac{1}{2}\) x - 4 ← equation of perpendicular line

Answer:

You are 30!

Step-by-step explanation:

30 IS a multiple of 3, 5, and 10:)

The number that is a multiple of 3, 5, and 10 and is less than 100 is 30.To find the number that is a multiple of 3, 5, and 10 and is less than 100, we can find the least common multiple (LCM) of 3, 5, and 10. The LCM is the smallest positive integer that is divisible by all three numbers.

The prime factorization of these numbers is as follows: 3: 3

- 5:5

- 10:\(\(2 \times 5\)\)

The LCM is the product of the highest powers of all prime factors involved. In this case, since 10 already includes the prime factors of 2 and 5, we just need to multiply by 3 to include the prime factor of 3:

LCM =\(\(2 \times 5 \times 3 = 30\)\)

So, the number that is a multiple of 3, 5, and 10 and is less than 100 is 30.

The least common multiple (LCM) is the smallest positive integer that is evenly divisible by a set of numbers. In this case, we're looking for a number that is a multiple of 3, 5, and 10, and is less than 100.

Prime factorization is the process of breaking down a positive integer into a product of prime numbers. A prime number is a number greater than 1 that has no positive divisors other than 1 and itself. Prime factorization is a fundamental concept in number theory and is used to understand the fundamental building blocks of numbers.

The task is to construct the addition and multiplication tables for the quotient ring 2Z/8Z, which represents the integers modulo 8 with 2Z as the equivalence class of even integers.

The question also asks whether 2Z/8Z and Z4 are isomorphic rings. To construct the addition and multiplication tables for 2Z/8Z, we need to determine the equivalence classes and perform the operations modulo 8. The addition table will show the results of adding two equivalence classes, while the multiplication table will show the results of multiplying two equivalence classes. For the addition table, we consider all possible pairs of equivalence classes [a] and [b] in 2Z/8Z and find their sum modulo 8. For example, [2] + [4] = [6], as 2 + 4 ≡ 6 (mod 8). Similarly, we calculate the sum for all pairs to complete the addition table.

For the multiplication table, we follow the same process. We multiply the equivalence classes [a] and [b] modulo 8 to find their product. For example, [2] * [4] = [0], as 2 * 4 ≡ 0 (mod 8). We repeat this for all pairs to construct the multiplication table. To determine whether 2Z/8Z and Z4 are isomorphic rings, we need to check if there exists a bijective ring homomorphism between the two rings. In other words, we need to find a mapping that preserves the ring structure and is one-to-one and onto.

In this case, both 2Z/8Z and Z4 have 8 elements. We can compare their addition and multiplication tables to check if they are the same. If the tables are identical, it indicates that the rings are isomorphic. However, if there is a difference in the tables, they are not isomorphic. By examining the addition and multiplication tables for 2Z/8Z and Z4, we can determine if the two rings are isomorphic or not.
