Answer:
See below.
Step-by-step explanation:
So we have a function f(x) which is:
[tex]f(x)=5+350x[/tex]
And this represents the total cost (f(x)) in dollars for renting a beach house for x days.
If we use 5 for x:
[tex]f(5)=5+350(5)[/tex]
Multiply:
[tex]f(5)=5+1750=1755[/tex]
This means that the total cost to rent the beach house for 5 days is $1755.
Answer:
The cost of renting the house for 5 days
$1755 for 5 days
Step-by-step explanation:
We are given the function:
f(x) = 5+350x
f(x) represents the total cost in dollars and x represents the days.
If we want to find f(5), we must substitute 5 in for x.
f(5) = 5+350(5)
Multiply 350 and 5.
f(5)= 5+ 1750
Add 5 and 1750.
f(5)= 1755
x represents days and we substituted 5 in for x. Therefore, f(5) represents the cost of renting the beach house for 5 days. f(5) is equal to 1755.
So, It will cost $1755 to rent the beach house for 5 days.

Answer:
(0, - 23 )
Step-by-step explanation:
Find the equation of the line in slope- intercept form
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 72, 25) and (x₂, y₂ ) = (- 36, 1) ← 2 ordered pairs from the table
m = [tex]\frac{1-25}{-36+72}[/tex] = [tex]\frac{-24}{36}[/tex] = - [tex]\frac{2}{3}[/tex] , thus
y = - [tex]\frac{2}{3}[/tex] + c
To find c substitute any ordered pair into the equation
Using (- 54, 13 ) , then
13 = 36 + c ⇒ c = 13 - 36 = - 23 ← y- intercept
Thus coordinates of y- intercept = (0, - 23 )
what is fifty five plus seventy two divided by three
Hey There!!~
Answer: 42
Because, 55 + 72 = 127. After you should do 3 ÷ 127. The divisor (3) goes into the first digit of the dividend (1), 0 times. Therefore, put 0 on top. Then you should Multiply the divisor by the result in the previous step (3 × 0 = 0) and write that answer below the dividend. After that Subtract the result in the previous step from the first digit of the dividend (1 - 0 = 1) and write the answer below. Move down the 2nd digit of the dividend in the below. The divisor (3) goes into the bottom number (12), 4 time(s). Therefore, put 4 on top... Subtract the result in the previous step from the number written above it. (12 - 12 = 0) and write the answer at the bottom. Move down the last digit of the dividend in the below. The divisor (3) goes into the bottom number (7), 2 time(s). Therefore put 2 on top, Multiply the divisor by the result in the previous step (3 x 2 = 6) and write the answer at the bottom... Subtract the result in the previous step from the number written above it. (7 - 6 = 1) and write the answer at the bottom. The answer is the top number and the remainder is the bottom number.
Therefore, the answer to 127 divided by 3 calculated using Long Division is

Answer:
-13
Step-by-step explanation:
What the Answer please?
Answer:
x = 151
Step-by-step explanation:
In the figure given, x is an exterior angle of the ∆.
According to the exterior angle theorem, x = the sum of the two opposite interior angles of the ∆.
One of the opposite angles measures 101°, while the second opposite angle equal 50°, since line l is parallel to m, alternate interior angles are equal.
Therefore, x = 101 + 50 = 151°

X and Y are modeled inflation rates, in terms of %, for two different countries at the end of a five-year period. X is uniformly distributed on the interval (0, 10). Y, given X = x is uniformly distributed on the interval (0, x). Calculate Cov(X, Y).
Answer:
The value of Cov (X, Y) is 25/6.
Step-by-step explanation:
It is provided that:
[tex]X\sim U(0,10)\\\\Y|X\sim U(0,x)[/tex]
The probability density functions are as follows:
[tex]f_{X}(x)=\left \{ {{\frac{1}{10};\ 0<X<10} \atop {0;\ \text{otherwise}}} \right. \\\\f_{Y|X}(y|x)=\left \{ {{\frac{1}{x};\ 0<Y<x} \atop {0;\ \text{otherwise}}} \right.[/tex]
Then the value of f (x, y) will be:
[tex]f_{X,Y}(x,y)=\left \{ {{\frac{1}{10x};\ 0<X<10,\ 0<Y<x} \atop {0;\ \text{Otherwise}}} \right.[/tex]
Then f (y) is:
[tex]f_{Y}(y)=\int\limits^{10}_{y} {\frac{1}{10x}} \, dx[/tex]
[tex]=\frac{1}{10}\times [\log x]^{10}_{y}\\\\=\frac{1}{10}[\log 10-\log y][/tex]
Compute the value of E (X) as follows:
[tex]E(X)=\frac{b+a}{2}=\frac{10+0}{2}=5[/tex]
Compute the value of E (Y) as follows:
[tex]E(Y|X)=\frac{b+a}{2}=\frac{x+0}{2}=\frac{x}{2}\\\\\text{Then,}\\\\E(E(Y|X))=E(\frac{x}{2})\\\\E(Y)=\frac{1}{2}\times E(X)\\\\E(Y)=\frac{5}{2}[/tex]
Compute the value of E (XY) as follows:
[tex]E(XY)=\int\limits^{10}_{0}\int\limits^{x}_{0} {xy\cdot \frac{1}{10x}} \, dx dy[/tex]
[tex]=\int\limits^{10}_{0}\int\limits^{x}_{0} {\frac{y}{10}} \, dx dy\\\\=\frac{1}{10}\times \int\limits^{10}_{0}{\frac{y^{2}}{2}}|^{x}_{0} \, dx \\\\=\frac{1}{10}\times \int\limits^{10}_{0}{\frac{x^{2}}{2}}\, dx\\\\=\frac{1}{10}\times [\frac{x^{3}}{6}]^{10}_{0}\\\\=\frac{100}{6}\\\\=\frac{50}{3}[/tex]
Compute the value of Cov (X, Y) as follows:
[tex]Cov (X, Y)=E(XY)-E(X)E(Y)[/tex]
[tex]=\frac{50}{3}-[5\times\frac{5}{2}]\\\\=\frac{50}{3}-\frac{25}{2}\\\\=\frac{100-75}{6}\\\\=\frac{25}{6}[/tex]
Thus, the value of Cov (X, Y) is 25/6.

Over the past several months, the water level of a lake has been decreasing by 3% each week. If the highest water level before the decrease started was 520 ft, what was the level at the end of 8 weeks?
Answer:
y= 407.54654 ft
Step-by-step explanation:
This is an exponential decay functions
y = ab^x where a is the initial value and b is ( 1 - rate of decay)
a = 520
b = 1- 3%
y = 520 ( 1- .3) ^x
y = 520 ( .97) ^x
We want x to be 8 weeks
y = 520 ( .97) ^8
y= 407.54654 ft

Try to calculate the arc elasticity percentage change from 80 to 100. Input your answer in percent form.
Answer: the arc elasticity percentage change from 80 to 100 is 22%
Step-by-step explanation:
formula for arc-elasticity percentage change is given as;
{ [Xₙ - X₀] / [ (X₀+Xₙ) / 2] } × 100
X₀ is old value, Xₙis new value
Now from our question
old value X₀ = 80
new value Xₙ = 100
WE SUBSTITUTE
Arc-Elasticity = { [100 - 80] / [ (80+100) / 2] } × 100
Arc-Elasticity = { [20] / [ 180 / 2] } × 100
Arc-Elasticity = (20/90) × 100
Arc-Elasticity = 22.22 ≈ 22%
Therefore the arc elasticity percentage change from 80 to 100 is 22%
In this exercise we have to use the percentage knowledge, in order to calculate the arc elasticity, so:
the arc elasticity percentage is 22%
First, we have that the formula for the elastic arc is:
[tex]([X_n - X_0] / [ (X_0+X_n) / 2] } * 100[/tex]
X₀ is old value, Xₙis new value
Informed the exercise data as:
old value X₀ = 80 new value Xₙ = 100
Substituting the values in the formula given above, we find that:
[tex]Arc-Elasticity = { [100 - 80] / [ (80+100) / 2] } * 100\\Arc-Elasticity = { [20] / [ 180 / 2] } * 100\\Arc-Elasticity = (20/90) *100\\Arc-Elasticity = 22%[/tex]

What is an area?The area of a 2D form is the amount of space within its perimeter. It is measured in square units such as cm², m², and so on. To find the area of a square formula or another quadrilateral, multiply its length by its width.
Given that Elias completely covered a square canvas using 77.8 in.² of fabric without any overlap. Therefore, the area of the canvas will be equal to the area of the fabric. Thus, we can write,
Area of the canvas = Area of the fabric
Since the area is square, therefore,
Area of the canvas = Area of the fabric
Area of the canvas = 77.8 in.²
Side of the canvas = √(77.8 in.²)
