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

"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

Answer:
{2, 2, 2}, {2, 3, 3}, {2, 4, 4}, {3, 2, 3}, {3, 3, 2}, {3, 3, 4}, {3, 4, 3}, {4, 2, 4}, {4, 3, 3}, {4, 4, 2}, {5, 2, 5}, {6, 2, 6}
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.
Here are two spheres, with

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.

Samantha plays a trivia game. She earns 3 points for each
correct answer and loses 0.75 points for each incorrect
answer. She gets 11 correct answers and 4 incorrect
answers.
What is her score for the game?
Answers
Answer:
33/36
Step-by-step explanation:
take 0.75 x 4 = 3
then take
11 x 3 = 33
total score = 36
36 - 3 = 33
so the answer is 33/36
Answer:
Samantha would score 30 points
Step-by-step explanation:
If we multiply 11 x 3 we would get 33, the 11 represents the correct awnsers and the 3 represents the points
If we multiply 0.75 and 4 we get 3, this represents the incorrect
Next I subtracted 33 and 3 to get the answer of 30.

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.

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

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.

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
