5. Find all the solutions to the equation x²e^x– 2xe^x – 3e^x =0.

Answer: choice3) 25

Step-by-step explanation:

The constant ratio of y/x is 2.5

so if the x value is 10 the y value would be 25(10*2.5).

For a relation to be a function, each member of the domain must have a corresponding member in the range. This means that no input ( i.e. x) must have more than one output.

Therefore, to identify if a graph is a function, draw a vertical line across the graph, if the vertical line touches or intersects the graph at more than one point, it means it is not a function.

Answer:

the are so many numbers but here's one of them

Step-by-step explanation:

Since the number is less than 700, it cannot begin with a 7 or an 8.

So the hundreds digit can only be a 2 or a 5.

Now the tens digit can be any digit not occupying the hudreds digit. So there would be 3 possibilities, and there remain two possibilities for the units digit.

Hence, the number of such numbers is 2x3x2 which is 12.

The number of two-digit or three-digit numbers that can be made using the digits 1, 7, 8, 5, and 2 will be 150.

A sample is a group of clearly specified components. The number of items in a finite set is denoted by a curly bracket.

The number of two-digit numbers that can be made using the digits 1, 7, 8, 5, and 2 is calculated as,

⇒ 5 x 5

⇒ 25

The number of three-digit numbers that can be made using the digits 1, 7, 8, 5, and 2 is calculated as,

⇒ 5 x 5 x 3

⇒ 125

The number of two-digit or three-digit numbers that can be made using the digits 1, 7, 8, 5, and 2 is calculated as,

⇒ 125 + 25

⇒ 150

Answer: 49

Step-by-step explanation:

\(-11\frac{2}{3}*-4\frac{1}{5}\)

The first thing we are going to do is to convert to an improper fraction. To do this, you take the whole number, you multiply it by the denominator and add the numerator; all over the same denominator.

\(-\frac{11*3+2}{3}*-\frac{4*5+1}{5}\)

Solve;

\(-\frac{33+2}{3}*-\frac{20+1}{5}\)

\(-\frac{35}{3}*-\frac{21}{5}\)

Now you can simply multiply numerators and denominators. Also, remember the negative signs which become positive because -*-=+

Before multiplying, it's easier to solve fractions that are being multiplied if you simplify them.

35 and 5 can be simplified.

35/5=7

5/5=1

21 and 3 can be simplified.

21/3=7

Answer:

Option (A)

Step-by-step explanation:

Like fractions possess a shared denominator while not necessarily having identical numerical values. To determine which pair of numbers contains like fractions, we need to analyze each pair of fractions and see if they have the same denominator. Let's examine each pair:

Option (A) 1/2 and 3/2:

These fractions are like fractions because their denominators are the same value.

Option (B) 4/8 and 12/16:

These fractions are not like fractions because their denominators are not the same value.

Option (C) 6/7 and 60/70:

These fractions are not like fractions because their denominators are not the same value.

Option (D) 5/4 and 4/5:

These fractions are not like fractions because their denominators are not the same value.

The pair of numbers that contains like fractions is A. 1/2 and 3/2.

if Jenny chooses to buy from Daikin, the monthly installment price would be approximately RM98.89, and the total installment price to be paid would be approximately RM1,779.98 (18 monthly installments * RM98.89).

Calculating the loan amount for each brand by subtracting the down payment from the cash price:

Loan amount for Daewoo = RM1,899 - RM300 = RM1,599

Loan amount for Daikin = RM1,699 - RM300 = RM1,399

Loan amount for Mitsubishi = RM1,999 - RM300 = RM1,699

Calculating the interest charge for each brand:

Interest charge for Daewoo = Loan amount for Daewoo * Interest rate = RM1,599 * 0.04 = RM63.96

Interest charge for Daikin = Loan amount for Daikin * Interest rate = RM1,399 * 0.04 = RM55.96

Interest charge for Mitsubishi = Loan amount for Mitsubishi * Interest rate = RM1,699 * 0.04 = RM67.96

To find the monthly installment price, divide the total amount (cash price + interest charge) by the number of monthly installments:

Monthly installment price for Daewoo = (Cash price of Daewoo + Interest charge for Daewoo) / Number of monthly installments = (RM1,899 + RM63.96) / 18 ≈ RM107.22

Monthly installment price for Daikin = (Cash price of Daikin + Interest charge for Daikin) / Number of monthly installments = (RM1,699 + RM55.96) / 18 ≈ RM98.89

Monthly installment price for Mitsubishi = (Cash price of Mitsubishi + Interest charge for Mitsubishi) / Number of monthly installments = (RM1,999 + RM67.96) / 18 ≈ RM116.72

Therefore, if Jenny chooses to buy from Daikin, the monthly installment price would be approximately RM98.89, and the total installment price to be paid would be approximately RM1,779.98 (18 monthly installments * RM98.89).

A ∪ B: The union of sets A and B includes all unique elements from both sets, resulting in {10, 11, 12, 13, 14, 16}.

A ∩ B: The intersection of sets A and B includes only the common elements between the two sets, which are {10, 12}.

A ∪ C: The union of sets A and C combines all unique elements, resulting in {7, 8, 9, 10, 11, 12, 13}.

A ∩ C: The intersection of sets A and C includes only the common elements, which is {10, 11}.

Step-by-step explanation:

y = 1 4 x calculates the number of eggs, y, for x crepes. The constant of proportionality is 1 4 . Ella needs 15 eggs to make 60 crepes. y = kx, where k is the constant of proportionality → y = 5 eggs 20 crepes x → y = 1 4 x; thus, k = 1 4 y = 1 4 (60) = 15 eggs

For 60 creps, 15 eggs will be needed.

Given is that the number of eggs used in the recipe is proportional to the number of crepes being made. The recipe calls for 5 eggs per 20 crepes. Sixty crepes will be served

Now, for 20 creps, 5 eggs are needed.

Then for 1 crep, (5/20) eggs are needed.

For 60 creps, (5/20) x 60 = 15 eggs will be needed.

Therefore, For 60 creps, 15 eggs will be needed.

The required value f x for given adjacent angles is 7.

When two angles have a similar vertex and side, they are referred to as neighboring angles. The vertex of an angle is the point at which the rays that make up its sides come to an end. When adjacent angles have a same vertex and side, they can be a complimentary angle or supplemental angle.

The sum of the measures of the two adjacent angles is given as 135. Therefore, we can write an equation as:

(2x+45) + (3x+55) = 135

Simplifying and solving for x:

5x + 100 = 135

5x = 35

x = 7

Therefore, the value of x is 7.

Answer:  y=1/x+5-1

Step-by-step explanation:

The fourth term a₄ of the sequence is 29933

From the question, we have the following definition of the function that can be used in our computation:

a₁= 3

aₙ = (aₙ₋₁)² + 4

The above definitions imply that we simply square the previous term and then add 4 to the squared result to get the current term

Using the above as a guide,

so, we have the following representation

a₂ = (3)² + 4

a₂ = 13

Also, we have

a₃ = (13)² + 4

a₃ = 173

Lastly, we have

a₄ = (173)² + 4

Evaluate the equation

a₄ = 29933

Hence, the value of a₄ is 29933

Answer: To factorize the expression 6x + 8 fully, we can first look for the greatest common factor (GCF) of the two terms. In this case, the GCF is 2.

Step 1: Factor out the GCF:

2(3x + 4)

Now, we have the expression 3x + 4 inside parentheses. This expression cannot be further factorized since there are no common factors other than 1.

Therefore, the fully factorized form of 6x + 8 is:

2(3x + 4)

Step-by-step explanation:)

The factored expression is:

Step-by-step explanation:

To factor the expression, look at its GCF (greatest common factor).

Clearly the GCF of both terms is 2. So what we do next is we divide both terms by 2 :

Step-by-step explanation: I just know

The property you are referring to is called the associative property of multiplication. According to this property, when multiplying three numbers, the grouping of the numbers does not affect the result. In other words, you can change the grouping of the factors without changing the product.

In the equation you provided: 3x(5x7) = (3x5)7

The associative property allows us to group the factors in different ways without changing the result. So, whether we multiply 5 and 7 first, or multiply 3 and 5 first, the final product will be the same.

Answer:

okay i'll keep this in mind

Step-by-step explanation:

The point on the number line represents the product is (a) point A

From the question, we have the following parameters that can be used in our computation:

Product = (-4)(-2)(-1)

Express as products

So, we have

Product = (-4) * (-2) * (-1)
