An electric board determines its monthly bills for residential customers by charging a base price of $11.00 plus an energy charge of 10.34 cents for each kilowatt-hour (kWh) used. Write an equation for the monthly charge y (in dollars) as a function of x, the number of kWh used.
The equation for the monthly charge as function of the number of kWh used is: y = 10.34x + 11.00.
How to Write a Linear Function?A linear function, where y is a function of x, is expressed as, y = mx + b, where:
the initial value/starting value = b (y-intercept)the unit rate/rate of change = m (slope)Using the information given:
The initial value of the function = b (y-intercept) = 11.00
the unit rate of the function = m (slope) = 10.34
To write the equation that represents the monthly charge (y in dollars) as function of kWh used (x), substitute m = 10.34 and b = 11.00 into y = mx + b:
y = 10.34x + 11.00
Therefore, the equation for the monthly charge as function of the number of kWh used is: y = 10.34x + 11.00.

What is the reference angle for the angle with the measure 2x/3
The reference angle for the angle with the measure 2x/3 is 54⁰
How to determine the reference angle?You should understand that a reference angle is the acute angle to a given angle.
The given angle is 2x/3
We should understand that since the angle has the variable x
= x + 2x/3 = 90⁰
Simplifying the fraction to have
(3x+2x)/3 = 90
Cross and multiply we have 5x=270⁰

What is x? Because I don’t know g how to work it out
Answer:
45 degrees
Step-by-step explanation:
The 4 angles of a quadrilateral will add to 360.
We know 1 of them (angle B) is 90 degrees.
We can set up an equation to solve the others.
2x+3x+x+90 = 360
Now solve for x.
Start by combining the x terms together.
6x+90 = 360
6x = 360-90
6x = 270
(6x/6) = 270/6
x = 45 degrees
Check back to see if that makes sense and if the equation equals 360 when x is 45:
2x+3x+x+90 = 360
2(45)+3(45)+45+90=360.

What are the zeros of the polynomial function f(x)=x3-7x2+8x+16
Answer: x=4, -1
Step-by-step explanation:
Assuming you meant \(x^3-7x^2+8x+16\), the zeros of the question are x = 4 and -1.
Step 1. Replace f(x) with y.
\(y = x^3-7x^2+8x+16\)
Step 2. To find the roots of the equation, replace y with 0 and solve.
\(0 = x^3-7x^2+8x+16\)
Step 3. Factor the left side of the equation.
\((x-4)^2 (x+1)=0\)
Step 4. Set x-4 equal to 0 and solve for x.
\(x-4=0\)
Step 5. Set \(x+1\) equal to 0 and solve for x.
\(x=-1\)
The solution is the result of \(x-4=0\) and \(x+1=0\).

Explicación paso a paso:
Distancia total recorrida caminando de C a A pasando por T:
500 yardas + 700 yardas = 1200 yardas
Tiempo necesario para recorrer 200 yardas = 14 minutos
Caminando directamente de C a A:
La distancia se puede obtener usando una relación trigonométrica:

Hipotenusa = √500² + 700²
Hipoteno = 860.23252 yardas
Por eso ; Si
1200 yardas = 14 minutos
860.23252 yardas = x
Multiplicar en cruz:
1200x = 12043,255

A flower bed is in the shape of a triangle with one side twice the length of the shortest side and the third side is feet more than the length of the shortest side. Find the dimensions if the perimeter is feet.
I got you, buddy!
Let x be the length of the shortest side. Then, the length of the second side is 2x, and the length of the third side is x + y, where y is the additional length.
The perimeter of the triangle is the sum of the three sides, so we have:
x + 2x + (x + y) = 60
Simplifying this equation, we get:
4x + y = 60
We also know that the area of a triangle is given by:
A = (1/2)bh
where b is the length of the base, and h is the height. Since the base of the flower bed is the shortest side of length x, we can choose the height to be y. Therefore, we have:
A = (1/2)xy
Now we need to solve for x and y. We can use the equation for the perimeter to solve for y:
y = 60 - 4x
Substituting this into the equation for the area, we have:
A = (1/2)x(60 - 4x)
Simplifying and expanding, we get:
A = 30x - 2x^2
To maximize the area, we can take the derivative of A with respect to x and set it equal to 0:
dA/dx = 30 - 4x = 0
Solving for x, we get:
x = 7.5
Substituting this back into the equation for y, we get:
y = 60 - 4x = 45
Therefore, the dimensions of the flower bed are:
shortest side = x = 7.5 feet second side = 2x = 15 feet third side = x + y = 52.5 feet
A horticulturist working for a large plant nursery is conducting experiments on the growth rate of a new shrub.

Walter invests $100,000 in an account that compounds interest continuously and earns 12%. How long will it take for his money to triple? Round to the nearest tenth of a year.
Answer:
\( 300000= 100000 e^{0.12 t}\)
We divide both sides by 100000 and we got:
\( 3 = e^{0.12 t}\)
Now we can apply natural logs on both sides;
\( ln(3) = 0.12 t\)
And then the value of t would be:
\( t = \frac{ln(3)}{0.12}= 9.16 years\)
And rounded to the nearest tenth would be 9.2 years.
Step-by-step explanation:
For this case since we know that the interest is compounded continuously, then we can use the following formula:
\(A =P e^{rt}\)
Where A is the future value, P the present value , r the rate of interest in fraction and t the number of years.
For this case we know that P = 100000 and r =0.12 we want to triplicate this amount and that means \( A= 300000\) and we want to find the value for t.
\( 300000= 100000 e^{0.12 t}\)
We divide both sides by 100000 and we got:
\( 3 = e^{0.12 t}\)
Now we can apply natural logs on both sides;
\( ln(3) = 0.12 t\)
And then the value of t would be:
\( t = \frac{ln(3)}{0.12}= 9.16 years\)
And rounded to the nearest tenth would be 9.2 years.
the equation of a circle centered at the origin x^2 + y^2 = 64. what is the radius of the circle?
Answer:
r = 8 units
Step-by-step explanation:
The equation of the circle centered at the origin is x² + y² = r²
x² + y² = 64
x² + y² = 8²
r = 8 units
Answer:
8
Step-by-step explanation:
An equation of a circle is depicted by the notation \((x-h)^2+(y-k)^2=r^2\), where
- \((h,k)\) is the center point of the circle
- \(r\) is the radius (the span of units from the origin to the border of the circle)
In this unique problem, the center is the origin (0,0), so \(h\) and \(k\) respectively equal 0.
Since the equation of the circle is \(x^2+y^2=64\) , we must square root 64 since it's in it's \(r^2\) form to obtain the value of \(r\), which is the radius.
\(\sqrt{64}\)=±8
Despite mathematically, -8 or 8 will work in this case, you cannot have a negative radius; therefore, the radius of the circle is 8.

lender requires a minimum down payment of 18% of the value of the home. You have $29,000 cash available to use as a down payment toward a home. Determine the maximum home value that you can finance.
The maximum home value that can be financed is approximately $35,365.85.
Let's represent the maximum home value that can be financed by H.
If the minimum down payment is 18%, the amount financed is 100% - 18% = 82%.
Therefore, we have:
H × 82% = $29,000
Multiplying both sides by (1/82%), we get:
H = $29,000 / 82%
= $35,365.85
Hence, the maximum home value that can be financed is approximately $35,365.85.

The perimeter of quadrilateral ABCD is equal to 29.49 units.
How to calculate the perimeter of a quadrilateral?Mathematically, the perimeter of a quadrilateral can be calculated by summing up all of its four (4) side lengths:
P = AB + BC + CD + AD
Next, we would determine the distance between each of the points on quadrilateral ABCD by using this equation:
Distance = √[(x₂ - x₁)² + (y₂ - y₁)²]
Distance AB = √[(0 + 5)² + (3 - 4)²]
Distance AB = √[5² + (-1)²]
Distance AB = √26
Distance AB = 5.10 units.
For BC, we have:
Distance BC = √[(4 - 0)² + (-1 - 3)²]
Distance BC = √[4² + (-4)²]
Distance BC = √32
Distance BC = 5.66 units.
For CD, we have:
Distance CD = √[(4 - 4)² + (-5 - 1)²]
Distance CD = √[0² + (-6)²]
Distance CD = √36
Distance CD = 6 units.
For AD, we have:
Distance AD = √[(4 + 5)² + (-5 - 4)²]
Distance AD = √[9² + (-9)²]
Distance AD = √162
Distance AD = 12.73 units.
Substituting the given parameters into the formula, we have;
P = AB + BC + CD + AD
P = 5.10 + 5.66 + 6 + 12.73
P = 29.49 units.
