Step-by-step explanation:

The polynomial function g(x) = [tex]x^4 - x^5[/tex] has two zeroes, which are x = 0 and x = 1. This result is obtained by setting the polynomial equal to zero and solving for x.

The given polynomial function is g(x) = [tex]x^4 - x^5[/tex]. To find the zeroes of the polynomial, this function should equal zero. Thus, we have[tex]x^4 - x^5[/tex] = 0.

We can simplify this function by factoring out the common factor, which is [tex]x^4[/tex]. The function thus becomes [tex]x^4[/tex](1 - x) = 0.

A product equals zero when one (or more) of the factors is zero. So, we need to set each factor to zero and solve for x. Setting [tex]x^4[/tex]= 0, yields x = 0. Setting (1 - x) = 0 results in x = 1.

This process gives two values of x that satisfy the equation [tex]x^4[/tex](1 - x) = 0 and therefore, the polynomial function g(x) has two zeroes, specifically x = 0 and x = 1.

or

2(10+4) = 2(14) =28cm  ........ without distributive property

Final answer:

To calculate the sale price of the Game Boy with an original price of $50.00 and a discount of 2/5, you multiply the original price by the discount to find the amount reduced ($20), then subtract that from the original price to find the sale price ($30).

Explanation:

The question involves calculating the sale price of an item after a discount. Initially, the original price of the Game Boy is $50.00. The discount is given as 2/5 of the original price. To find the amount of discount, we multiply the original price by 2/5:

Discount = Original Price × Fraction of discount
Discount = $50 × 2/5
Discount = $20

Now, we subtract this discount from the original price to find the sale price:

Sale Price = Original Price - Discount
Sale Price = $50 - $20
Sale Price = $30

Therefore, the sale price of the Game Boy after the discount is $30.

Take the breadth as x,as its the smallest value--(1)

Length is 2 more than 5 times the breadth--(2)

perimeter=160m

l=2+5x

b=x

Perimeter=2(l+b)

2(2+5x+x)

=2(2+6x)

Opening the brackets

=4+12x

4+12x=160

12x=160-4

x=156/12

=13

Therefore , by substituting the value of x

l=2+5*13=67m

b=13m

To find the cost of admission to the fair, subtract the cost of the ride tickets from the total spent. The linear equation 2.50x + y = 55.50 can be used to calculate the cost for anyone. The coefficient on x represents the cost per ride ticket, while the constant represents the total amount spent on ride tickets and admission.

(A) To find the cost of admission to the fair, we need to subtract the cost of the ride tickets from the total spent. Since Henry bought 15 tickets and spent a total of $55.50, we can use the equation 2.50x + y = 55.50, where x represents the number of ride tickets. Substituting x = 15, we can solve for y to find the cost of admission.

(B) The linear equation that can be used to determine the cost for anyone who pays for ride tickets and fair admission is 2.50x + y = 55.50, where x represents the number of ride tickets and y represents the cost of admission.

(C) In the linear equation, the coefficient on x (2.50) represents the cost per ride ticket. The constant (55.50) represents the total amount spent on ride tickets and admission.

Answer: The mean of the data is 433.75, variance of the data is 99667.19 and the standard deviation of the data is 315.7011.

Explanation:

The given data is 900, 35, 500 and 300.

The number of observation is 4.

Formula of mean is,

[tex]\text{Mean}=\frac{\text{Sum of observations}}{\text{Number of observations}}[/tex]

[tex]\bar{X}=\frac{900+35+50+300}{4} =433.75[/tex]

The formula of variance is given below,

[tex]\sigma^2=\frac{1}{n}\sum{(X-\bar{X})^2}[/tex]

[tex]\sigma^2=\frac{398668.75}{4}[/tex]

[tex]\sigma^2=99667.19[/tex]

The variance of the data is 99667.19

[tex]\sigma=\sqrt{99667.19}[/tex]

[tex]\sigma=315.7011[/tex]

The standard deviation of the data is 315.7011.

The other information or values of given chart is shown in the attached table.

Answer:

i.  mean of the data is 402.5

ii.  variance of the data is 77556.25

iii.  standard deviation of the data is 278.49

Step-by-step explanation: (x - ⁻x)²

from the chart given to me, the observation are:  45, 340, 400, 825

i.  mean is the summation of the observation divided by number of observation. ∈x÷n =( 45 + 340 + 400 + 825)÷ 4 = 402.5

ii.  variance is the square of the difference between the observation and mean divided by the number of observation.

variance = (45-402.5)²+(340-402.5)²+(400-402.5)²+(825-402.5)²÷4=77556.5

A reasonable estimate for 697 times 82 would be 56,000

Rounding some number to a specific value is making its value simpler (therefore losing accuracy), mostly done for better readability or accessibility. Rounding to some place keeps it accurate on the left side of that place but rounded or sort of like trimmed from the right in terms of exact digits.

We could round both numbers to make estimation easier to find.

So let's consider that 82 is 80 and 697 is 700.

As we know that 8 x 7 is 56, then the product of them will be;

80 x 700 =  56,000.

Therefore, This is a great way to estimate of big numbers easily.

Hence, A reasonable estimate for 697 times 82 would be 56,000

It is a step graph with slope of 2.

Answer: C

Whenever you are unsure, choose a coordinate, plug it into the equation, and see if it makes a true statement.

I choose (1/2, 1)   →   1 = [2(1/2)]   →   1 = [1]   TRUE

I choose  (1, 2)    →    2 = [2(1)]    →   2 = [2]  TRUE

For this case we have that by definition, the equation in the form of slope-intersection is given by:

[tex]y = mx + b[/tex]

Where

Substituting the given point: [tex](x, y) = (2, -4)[/tex] and the cutoff point [tex]b = -2[/tex] we can find the slope,

We have:

[tex]-4 = m * 2-2\\-4 = 2m-2\\-4 + 2 = 2m\\-2 = 2m[/tex]

[tex]m =-\frac{2}{2}\\m = -1[/tex]

Answer:  Cole and his sister Chloe will take 81 minutes to clean the whole house.

Step-by-step explanation:

Total rooms in the house = 9

Total persons to clean the house = 2 (Cole and his sister Chloe)

Time taken by 1 person to clean one=18 minutes

Time taken by 2 persons to clean one room together=18 divided by 2 = 9 minutes

Time taken by 2 persons to clean 9 rooms (which is the total number of rooms in the house)=9 multiply 9 = 81 minutes

therefore, they will take 81 minutes to clean the whole house.

(10m – 6) – (7m – 4)

= 10m - 6 - 7m + 4

= 3m - 2

So

[10m + (–7m)] + [(–6) + 4]

= 3m + (-2)

= 3m - 2 ..............matching answer.

Answer

[10m + (–7m)] + [(–6) + 4]

To add or subtract any algebraic expression,  variables add or subtract with variables and constant term add or subtract with constant terms in the expression.

To solve given expression, we use [10m + (–7m)] + [(–6) + 4] expression.

Given expression is,

                               (10m – 6) – (7m – 4)

Now, variables add or subtract with variables and constant term add or subtract with constant terms in the above expression.

                        10m - 6 - 7m + 4

                      (10m - 7m) + (-6 + 4)

Step-by-step explanation:

Given a quadratic equation

x^2+10x+24 =0

We can use either formula or factorization method to solve this equation.

The last term is 24, it is a product of 6 and 4. Sum =6+4 =10

Hence factoring can be done easier

Split the middle term as 6x +4x

x^2+6x+4x+24 =0

x(x+6)+4(x+6)=0

(x+4)(x+6)=0

Either x+4 =0 or x+6 =0

x=-6 or x =-4

The value of x in the isosceles right triangle is 52.5.

The measure of the acute angle in an isosceles right triangle can be determined by setting the expression equal to 90 degrees:

(2x - 15) = 90

Simplifying the equation, we get:

2x = 90 + 15

2x = 105

x = 105/2

x = 52.5

Therefore, the value of x is 52.5.
