Find the value of f(-9).

Answers

Answer:

f(- 9) = 2

Step-by-step explanation:

f(- 9) is asking for the value of y when x = - 9

Locate x = - 9 on the x- axis

Then go vertically up to meet the graph at (- 9, 2 )

Thus when x = - 9, y = 2 , that is

f(- 9) = 2

Solve for X

Find x, y, and z such that x³+y³+z³=k, for each k from 1 to 100

Answers

Answer:

There are no solutions whenever k=4,5mod9.

This holds since it is not difficult to verify that for every integer n, we have n3=0,±1mod9.

Up till this year, there were just two values for k in the range 1..100 for which it was not known if there were a solution. These values are k=33,42.

Both values are now known to have solutions. See 42 is the answer to the question “

Here are two spheres, with
radii 3 cm and 4.5 cm
respectively. The surface
area of the smaller sphere is
367 cm. What is the surface
area of the larger sphere?
4.6 cm
3 cm
A) 417 cm2
C) 817 cm2
B) 547 cm2
D) 121.57 cm2

Answers

Given:

Radii of two spheres are 3 cm and 4.5 cm respectively.

Surface area of the smaller sphere is 367 cm.

To find:

The surface area of the larger sphere.

Solution:

We know that, area of similar spheres is proportional to the square of there radii.

[tex]\dfrac{A_1}{A_2}=\dfrac{(r_1)^2}{(r_2)^2}[/tex]

On substituting the values, we get

[tex]\dfrac{367}{A_2}=\dfrac{(3)^2}{(4.5)^2}[/tex]

[tex]\dfrac{367}{A_2}=\dfrac{9}{20.25}[/tex]

On cross multiplication, we get

[tex](367)(20.25)=9A_2[/tex]

[tex]7431.75=9A_2[/tex]

Divide both sides by 9.

[tex]\dfrac{7431.75}{9}=A_2[/tex]

[tex]825.75 =A_2[/tex]

Therefore, the area of larger sphere is 825.75 cm².

Note: All options are incorrect.

find the product if the sum of two numbers is 131 and the difference is 35

Please help: this is due in one hour. Please write let statements and equations.

Answers

Answer:

Step-by-step explanation:

let the two numbers be : x and y

x +y =131 , x-y= 35

by omitting :

x+y=135

x-y=35

cancel the ys with each other and add each side together

2x=135+35 = 170

to get x

x=170/2 =85

now u have the x time to get the y u can get it for any equation u like

85+y=135

y=135-85 = 50

the product = 85 x 50 = 4250

Tebor weighed 84 kg. he went running everyday and began to lose mass. after one month his mass was 78 kg. what was the percentage decrease?

Step-by-step explanation:

The requirement that side lengths be greater than 0 means that ...

y > x > 0

y > z > 0

Then possible values for x and z are 1, 2, 3, and possible values for y are 3, 4, 5, 6, 7.

When we list the possibilities, and exclude those that do not give isosceles triangles, we find the values of {a, b, c} can be those listed above.

Raul opened a savings account with $4800. Each week, d, Raul pays the dog sitter $20 from his savings account. Write a function, f(d) , that is equal to the amount of money in the account after Raul pays the dog sitter each week.

Answers

Answer:

The function is: f(d)=4800-20d

Step-by-step explanation:

With the information provided, the function to calculate the amount of money in the account after Raul pays the dog sitter each week would be equal to the amount he used to open the savings account minus the result of multiplying the amount he pays the dog sitter each week for the number of weeks:

f(d)=4800-20d

According to this, the answer is that the function is: f(d)=4800-20d.

"This summer, the water level of Lake Conroe changed by a rate of -1.5 feet per month. The water level at the beginning of May was 187 feet above sea level. What was the water level at the end of four months?" heelpppp asaapp

Answers

Answer:

181 feets

Step-by-step explanation:

Given that:

Rate of change in water level = - 1.5 feets per month

Water level at beginning of May = 187 feets above sea level

Water level at the end of 4 months =?

Total change after four months = rate of change per month * number of months

= - 1.5 * 4 = - 6 feets

Hence water level after 4 months :

187 feets + (-6 feets)

187 feets - 6 feets

= 181 feets

The value of the equation is f ( x ) = 1/ ( x - 2 )²

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Let the function be f ( x ) = A

Now , Vertical asymptote (VA) - It is a vertical line and hence its equation is of the form x = k. Vertical asymptotes are defined when the denominator of a rational function tends to zero

So , the function which represents the graph will be

f ( x ) = 1 / ( x - 2 )² be equation (1)

And , the graph of the function is given below

Hence , the equation is f ( x ) = 1 / ( x - 2 )²
