A company that sells circular hot tubs is ordering covers. The radius of each hot tub is 4 feet. They need to order 250 of them and the cost of the material is .75 per square foot. how much is it going to cost the company
Answer:
9420Step-by-step explanation:
Radius of a tub = 4 feet
Number of tubs = 250
Total area
250*π*4^2 = 250*3.14*16 = 12560 sq. feetCost of material
12560*0.75 = 9420Laisha's Internet Services designs websites and recently began a weekly advertising campaign
Laisha noticed an increase in her customers over a period of five consecutive weeks. Based on
the pattern shown in the graph, make a conjecture about the number of customers Laisha will
have in the seventh week.
Laisha will have 7 customers
Laisha will have 8 customers.
Laisha will have 9 customers
Laisha will have 10 customers
Answer:
she will have 8
Step-by-step explanation: because it passes through the origin
In the 7th week, Laisha will have 8 customers. Option B is correct.
Given that,
Laisha noticed an increase in her customers over a period of five consecutive weeks. Based on the pattern shown in the graph, make a conjecture about the number of customers Laisha will have in the seventh week is to be determined.
Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.
Here,
The slope of the function m = 1
y-intercept = 1
The equation that represents the condition,
y = x + 1
Where y = number of customers and x = number of weeks
Now for x = 7
y = 7 + 1
y = 8
Thus, in the 7th week, Laisha will have 8 customers. Option B is correct.

Convert 3200 kilograms into pounds. Round your answer to the nearest whole number.
Answer:
7054.792 rounded to the nearest whole it will be 7055
Step-by-step explanation:
The required converted value is 7054 pounds, which is 3200 kilograms into pounds.
As we all know, unit conversion is the process of transferring a quantity from one unit of measurement to another.
To convert kilograms to pounds, you can use the conversion factor: 1 kilogram = 2.20462 pounds.
It is the process of multiplying a given quantity by a conversion factor that combines the two corresponding units.
To convert 3200 kilograms to pounds, you can multiply it by the conversion factor:
3200 kilograms x 2.20462 pounds/kilogram ≈ 7054.08 pounds
Rounding this to the nearest whole number, the conversion is approximately 7054 pounds.

Find the equation of the line parallel to y = -1/2 - 4 and goes through the point (-2,-5)
Answer:
The equation of the line is y = - 1/2 x - 6
Step-by-step explanation:
The equations of parallel lines have the same slopes and different y-intercepts
The form of the linear equation is y = m x + b, where
m is the slope of the lineb is the y-intercept (value y at x = 0)To find b substitute x and y in the equation by the coordinates of a point on the line∵ The given equation is y = -1/2 x - 4
→ By comparing it by the form of the equation above
∴ m = -1/2
∵ Parallel lines have the same slope
∴ The slope of the line = -1/2
→ Substitute it in the form of the equation above
∴ y = - 1/2 x + b
∵ The line passes through the point (-2, -5)
→ To find b substitute x by -2 and y by -5
∴ -5 = -1/2 (-2) + b
∴ -5 = 1 + b
→ Subtract 1 from both sides
∴ -5 - 1 = 1 - 1 + b
∴ -6 = b
→ Substitute the value of b in the equation above
∴ y = - 1/2 x + (-6)
∴ y = - 1/2 x - 6
The equation of the line is y = - 1/2 x - 6

Solve algebraically for all the values of x -2x^5+14x^4-2x^3+14x^2=0
Answer:
0, 7, ± iStep-by-step explanation:
Solving for x
- 2x^5 + 14x^4 - 2x^3 + 14x^2=0x^5 - 7x^4 + x^3 - 7x^2 = 0x^2 ( x^3 - 7x^2 + x - 7) = 0x^2( x^2(x - 7) + (x - 7)) = 0x^2(x^2 + 1)(x - 7) = 0x^2 = 0 ⇒ x = 0x^2 + 1 = 0 ⇒ x^2 = -1 ⇒ x = ± ix - 7 = 0 ⇒ x = 7The solutions to the original equation -2x³ + 14x²- 2x³ + 14x² = 0 are x = 0, -0.391, 0.099, 7.293
To solve the equation algebraically, factor out an "x^2" term from each term:
x²(-2x³ + 14x²- 2x + 14) = 0
Now, we have two factors:
x² = 0
-2x³ + 14x² - 2x + 14 = 0
First, let's solve the first factor, which is a simple quadratic equation:
x² = 0
x = 0
Now, let's solve the second factor by factoring out a common factor of 2:
2(-x³ + 7x² - x + 7) = 0
Now,use the rational root theorem or synthetic division to find the roots of the cubic equation -x³ + 7x² - x + 7 = 0. However, in this case, the equation does not have any rational roots. Therefore, we need to use numerical methods or graphing techniques to find the approximate solutions.
Using numerical methods or graphing, we find that the approximate solutions for the equation -x³ + 7x² - x + 7 = 0 are:
x ≈ -0.391
x ≈ 0.099
x ≈ 7.293

The initial Velocity of that object would be zero.
What is initial velocity?Initial Velocity, denoted as u, is the velocity at time period t = 0. It is the speed at which motion first occurs. When gravity first exerts a force on an object, its initial velocity defines how quickly the object moves.
They are three initial velocity formulas:
(1) If time, acceleration, and final velocity are provided, the initial velocity is articulated as u = v – at
(2) If final velocity, acceleration, and distance are provided we make use of u² = v² – 2 as
(3) If distance, acceleration, and time are provided, the initial velocity is
s = ut + 1/2at²
Where,
Initial velocity = u,
Final Velocity = v,
time taken = t,
distance travelled or displacement = s,
acceleration = a
From the third formula of velocity
s = ut + 1/2at²
If u = 0
then s = 1/2at²
=> at² = 2s
=> t² = 2s/a
=>t = [tex]\sqrt{2\frac{s}{a} }[/tex]
Which is the same as the given equation
therefore, That object's initial velocity would be zero.

The access code to a house’s security system consists of eight digits. How many different codes are available if each digit can not be repeated? Please show work!
Answer:
Consider one of eight positions separately from all others. There are 10 possible ways to choose
a digit to place on this position since there are ten digits from 0 to 9, and this choice is
independent of all other positions since each digit can be repeated and there is no restriction on
how to choose digits.
So, we have 8 positions and each one is filled by a digit in 10 ways independently from each other,
therefore the total number of possible codes equals to ways it can be done for each independent
position multiplied altogether. This is 10 × 10 × … × 10 = 108
(100 million).
Answer: 108 different codes.

Find the average rate of change of the function over the given interval.
f(t) = 2t^2 − 1, [5, 5.1]
Compare this average rate of change with the instantaneous rates of change at the endpoints of the interval.
Answer:
Average rate of change = 20.2
Rate of change at the left endpoint : f' (5) = 4t = 20
Rate of change at the right endpoint : f' (5.1) = 4*5.1 = 20.4
Step-by-step explanation:
The average rate of change of the function
F(t) = 2t^2 - 1 , [ 5,5.1 ]
solution
[tex]\frac{f(5.1)-f(5)}{5.1 - 5}[/tex] = [tex]\frac{2*(5.1)^2-1-(2*5^2-1)}{0.1}[/tex] = [ 2 ( 26.01 - 25 ) / 0.1 ]

Rate of change at the left endpoint : f' (5) = 4t = 20
Rate of change at the right endpoint : f' (5.1) = 4*5.1 = 20.4
