We know that the area of a circle in terms of π will be πr². However the area with respect to the diameter will be a different story. The first step here is to find a function relating the area and diameter of any circle --- ( 1 )
For any circle the diameter is 2 times the radius,
d = 2r
Therefore r = d / 2, which gives us the following formula through substitution.
A = π(d / 2)² = πd² / 4
Hence the area of a circle as the function of it's diameter is A = πd² / 4. You can also say f(d) = πd² / 4.
Now we can substitute " d " as 4, solving for the area ( A ) or f(4) --- ( 2 )
f(4) = π(4)² / 4 = 16π / 4 = 4π - This makes the area of circle present with a diameter of 4 inches, 4π.
you design a new app for cell phones. your revenue for x downloads is given by f(x)=3x. your profit is $20 less than 90% of the revenue for x downloads create a function p to model the profit. find the profit for 90 downloads
Answer:
The Break Even point is the point at which the cost=revenue 14,980+20x=30x 14,980=10x 1,498=x a. 1,498 units must be sold to break even. At $20 per unit, the dollar amount will be $29,960 b. The profit function is P(x)=R(x)-C(x) So P(x)=30x-(14,980+20x) If you want to solve for this equation just enter the value of x we found for the break even point to get the answer.

The profit for 90 downloads will be;
⇒ P = $223
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
Your revenue for x downloads is given by,
⇒ f(x) = 3x
And, Your profit is $20 less than 90% of the revenue for x downloads create a function p to model the profit.
Now,
Since, Your revenue for x downloads is given by,
⇒ f(x) = 3x
And, Your profit is $20 less than 90% of the revenue for x downloads create a function p to model the profit.
Hence, We can formulate;
⇒ P = 90% of f (x) - 20
⇒ P = 90/100 × 3x - 20
⇒ P = 270x/100 - 20
⇒ P = 2.7x - 20
So, The profit for 90 downloads will be;
⇒ P = 2.7 × 90 - 20
⇒ P = $223
Thus, The profit for 90 downloads = $223

Answer:
2a). Height = 2 cm
2b). Surface area = 395.84 cm²
Step-by-step explanation:
2a). Volume of the cylinder = 308 cm³
Radius of the base of the cylinder = 7 cm
Formula to get the volume of a cylinder = πr²h
308 = π(7)²h
h = [tex]\frac{308}{49\pi }[/tex]
h = 2 cm
Therefore, height of the cylinder will be 2 cm.
2b). Formula to calculate the surface area of the cylinder = [tex]2\pi r(r + h)[/tex]
By substituting the values in the given formula,
S.A. = 2π(7)(7 + 2)
= 395.84 cm²
Therefore, Surface area of the cylinder is 395.84 cm².
Name a fourth point in plane UVX
Answer:
The correct option is;
W
Step-by-step explanation:
The number of points that defines a plane in a Euclidean space in all dimensions is either three points which are not on the same line, or two colinear points and a third point not on the line
The given points of the plane are UVX, which gives the plane as being diagonal to the cube and perpendicular to the side face of the cube.
The fourth point in plane UVX is therefore W.
Help me answer the following question.
Answer:
160 m
Step-by-step explanation:
you can approach this question with the thinking of simple math. First, you have the value of -85 rose by 30 means +30 and descending 105 means -105.
So, the calculation you will get is -85+30-105=-160. The negative means going down as the direction.

Answer: a) $481.62 b) $16,569.76
Step-by-step explanation:
The formula for compound interest is: [tex]A = P(1 + r)^t[/tex] where
A is the accrued amount (balance)P is the principle (initial deposit)r is the rate (convert percentage into a decimal)t is the time (number of years)Given: P = 3000, r = 1.15% (0.015), t = 10
[tex]A = 3000(1 + 0.015)^{10}\\\\\\A = 3000(1.015)^{10}\\\\\\A = 3,481.62[/tex]
Interest Earned = accrued amount - principle
= 3,481.62 - 3,000
= 481.62

The parallel sides of a trapezoid have lengths 9 cm and 12 cm. Draw one diagonal, dividing the trapezoid into two triangles. What is the ratio of their areas?
Answer:
Ratio of triangle = 3 : 4
Step-by-step explanation:
Given:
Parallel sides = 9 cm , 12 cm
Find:
Ratio of triangle
Computation:
Assume height = h
Area of triangle = [1/2]bh
Area of triangle (1) = [1/2](9)h
Area of triangle (1) = 4.5 h
Area of triangle (2) = [1/2](12)h
Area of triangle (2) = 6 h
Ratio of triangle = 4.5 h / 6 h
Ratio of triangle = 3 : 4

ASAP.....!help........!!
Answer:
360
Step-by-step explanation:
First, we need to solve the numbers in the parentheses.
(14-2)^2 = (14 - 2)(14 - 2) = 196 -56 +4 = 144 (Use FOIL)
Then, we multiply that by 5.
144 * 5 = 720
Finally, we divide by two to get our answer.
720 ÷ 2 = 360
Answer:
360.
Step-by-step explanation:
Step 1:
Combine and Determine sums of certain numbers: 12 = 22•3
(12)2 = (22•3)2 = 24 • 32 =
--5 • (24•32) /2
Step 2:
Simplify: 24•32) /2 =
--5 • 72
Step 3:
Multiply: 360
Find the midpoin, M, of AB
Answer:
11
Step-by-step explanation:
The midpoint of AB is half the distance from A to B. Here that distance is 22. Thus, the midpoint of AB is 11.
Answer:
Hey there!
The answer is 11. We can use the midpoint formula, but since this is a number line, we can easily see that 11 is half of 22.

As of Sunday evening, José has collected 172 clothing items and Biruk has collected 1 clothing item for the clothing charity drive. José says he will collect 6 items per day. Biruk says he will collect 15 items per day. How many days from Sunday will it take until they have collected the same total number of clothing items for the charity drive?
Answer:
It will take 19 days from Sunday.
Step-by-step explanation:
You can use the equation 172 + 6d = 1 + 15d for this equation. 172 and 1 are how many items Jose and Biruk started with. 6d and 15d represent how many items they get a day. Here's how you can solve the equation:
172 + 6d = 1 + 15d
-6d -6d
172 = 1 + 9d
-1 -1
171 = 9d
÷9 ÷9
19 = d (write it as d = 19)
(When you type the answer, be sure to always put the letter first.)
The Trumbull Tree Farm sold 390 trees last week. All of the trees were either evergreens, oaks, or maples. Twice as many oak trees as evergreen trees were sold. 5 times as many maple trees as oak trees were sold.
How many oak trees were sold last week?
Answer:
60
Step-by-step explanation:
We can use x to represent the number of oak trees.
This means evergreen trees will be 1/2x and 5x will be the maple trees.
Set up an equation:
x + 1/2x + 5x = 390
6.5x = 390
x = 60
So, 60 oak trees were sold last week.

Answer:
£13
Step-by-step explanation:
Set up a system of equations where s represents the cost of one shirt and j represents the cost of one jumper:
2s + j = 29
s + j = 21
Multiply the bottom equation by -2 to solve by elimination by cancelling out the s variables:
2s + j = 29
-2s - 2j = -42
-j = -13
j = 13
One jumper will cost £13

AB = 2x-5 BC = 6x AC = 27
Answer:
correct answer is x = 2.75
Step-by-step explanation:
Given;
AB = 2x-5
BC = 6x
AC = 27
Hence,
=> AC = AB + BC
=> 27 = 2x-5 + 6x
=> 27 = 8x-5
=> 27-5 = 8x
=> 22 = 8x
=> 22/8 = x
=> 11/4 = x
or
2.75 = x

dante’s cell phone company charges $45 per month for unlimited calls and internet use and $0.25 per text message. his last cell phone bill was $60.50. how many text messages did he send last month. write an equation.
Answer:
242 text messages.
Step-by-step explanation:
60.50 / 0.25 = 242
60.50 being the phone bill.
0.25 being each text message.
/ stands for ' divided by '.
Answer:
62 text messages
Step-by-step explanation:
Let the number of text messages be x,
Then the required equation:
0.25x + 45 = 60.50Solution:
0.25x = 60.50 - 450.25x = 15.50x = 15.50/0.25x = 62Answer is: 62 text messages
I need to find the value of x and y. HELP PLEASE
Answer:
The answer is option C
Step-by-step explanation:
Since the triangle is a right angled triangle we can use trigonometric ratios to find x and y
For xIn order to find x we use tan
tan∅ = opposite/ adjacent
From the question
The opposite is 4
The adjacent is x
Substitute the values into the above formula
That's
[tex] \tan(30) = \frac{4}{x} \\ x \tan(30) = 4 \\ x = \frac{4}{ \tan(30) } [/tex]We have the answer as
[tex]x = 4 \sqrt{3} [/tex]For yIn order to find y we use sine
sin ∅ = opposite / hypotenuse
From the question
The opposite is 4
The hypotenuse is y
So we have
[tex] \sin(30) = \frac{4}{y} \\ y \sin(30) = 4 \\ y = \frac{4}{ \sin(30) } [/tex]We have the answer as
y = 8Hope this helps you
