The surface area is [tex]4\sqrt{2} \pi[/tex] units.
This problem is related to the triangle and solid figures.
If we rotate a triangle alongside one of its legs then it's going to shape a cone and the radius of the cone might be the duration of the bottom of the triangle and the hypotenuse of the triangle may be the slant peak of the cone.
The period of the the triangle legs is given to be 2 units.
Length of the hypotenuse=[tex]\sqrt{2^{2} +2^{2} }[/tex]
= [tex]2\sqrt{2}[/tex] units.
Now the area of the cone is given by [tex]\pi rl[/tex] where r is the radius of the cone and l is the slant height of the cone.
Surface area of cone = [tex]\pi *2*2\sqrt{2}[/tex]
= [tex]4\sqrt{2} \pi[/tex] units
So, the surface area of cone is [tex]4\sqrt{2} \pi[/tex] units.

The hash marks on the segments of the triangle indicate congruence. The "one hash mark" segments are congruent to each other, and the "two hash marks" segments are congruent to each other. That is, two corresponding sides are marked congruent.
Similarly, the arc on the angle indicates the angle is congruent to one with a similar mark. We notice that the marked angle is between the sides that have hash marks. So, we have, in order around the triangle, congruent Sides, Angles, Sides. The appropriate choice is ...

a bus is traveling at a velocity of 25 m/s straight south what effect will an acceleration of 4m/s2 north have on a bus
Answer:
The acceleration will cause the bus to travel for 6.25secs
Step-by-step explanation:
For us to get the effect the acceleration will have on the bus, we need to calculate the time taken by the bus to travel.
Using the acceleration formula;
Acceleration = Velocity/Time
Given
Acceleration = 4m/s²
Velocity = 25m/s
Required
Time
From the formula;
Time = Velocity/acceleration
Time = 25/4
Time = 6.25secs
Hence the acceleration will cause the bus to travel for 6.25secs

what is 4h-8h in like terms and terms and identify expression
Answer:
4h
Step-by-step explanation:
Expression: 4h-8h=4h
Because both 4h and 8h end in the same variable they can be subtracted when you subtract 4 and 8 you get 4. and You can't forget your variable so you end with 4h
Your expression is a group of terms without an equal sign. 4h and 8h are your terms as well as your answer.
Your expression ends as 4h-8h=4h
The formula to determine the period of one swing of a simple pendulum is T=2\pi\sqrt{\frac{L}{g}},T=2π g L , where LL is the length of the string and gg is the acceleration due to gravity. Solve the formula to solve for LL in terms of \pi,π, TT and g.G.
Answer:
L = (T² × g) / 4π²
Step-by-step explanation:
T = 2π√L/g
Where,
L = length of the string
g = acceleration due to gravity
T = 2π√L/g
square both sides of the equation to eliminate the square root
T² = (2π)²√(L/g)²
T² = (2π)²(L/g)
(2π)²
= 2π × 2π
= 4π²
T² = 4π²(L/g)
Multiply both sides by g
T² × g = 4π²(L/g) × g
T² × g = 4π²L
Divide both sides by 4π² to get L
L = (T² × g) / 4π²

(pre-calc) Use Limit Laws to determine the limit of a(n). It is not -∞, so what answer is it and why?
The limit of the function as the variable n tends to minus infinity is -1
Limit of a functionGiven the limit of a function expressed according to the equation;
a(n) = 6n²-n-3n³/3n³+n-1
The value of the function if n tends to minus infinity is expressed as show:
a(n) = 6n²-n-3n³/3n³+n-1
Divide both all the terms by n³
a(n) = 6n²/n³-n/n³-3n³/n³/3n³/n³+n/n³-1/n³
a(n) = 6/n-1/n²-3/(3+1/n²-1/n³)
a(n) = 6/-∞ - 1/(-∞)²-3/(3+1/(-∞)²-1/(-∞)³)
a(n) = -3/3
a(n) = -1
Hence the limit of the function as the variable n tends to minus infinity is -1

The shape is composed of three squares and two semicircles.Select all the expressions that correctly calculate the perimeter of the shape
Answer:
100+20π
Step-by-step explanation:
Find the diagram attached.
Perimeter of a square =4L
L is the side length of a square
From the diagram;
L = 10
Perimeter of a square = 4(10) = 40
Perimeter of 3 squares = 3(40) = 120
2 semi circle = a circle
Perimeter of a circle= 2πr
radius of the Circle = length of a side of the square.
Area of the circle = 2π(10)= 20π
Perimeter of the shape = Perimeter of the two semicircle + area of the 4squares = 100+20π

To get the prime factorization of 72, break 72 down into primes
72 = 9*8
Both 9 and 8 are not prime, so break 9 and 8 down
= 3*3 * 4*2
4 is not prime so break 4 down

At the market, a farmer is selling carrots and potatoes by the pound. The table below shows the amount of each (in pounds) purchased by two customers and the total amount paid (in dollars).
Based on the table on the amount of carrots and potatoes purchased, the cost of each pound of carrots and potatoes are Cost per pound of carrots: $1.50 and per pound of potatoes: $2.00
What is the cost?As you have been given options, you can use the prices in the options to see which price tallies with the total amount that each customer paid.
If you checked all the options, you would find the correct option is the correct option.
The first customer would pay:
= (4 x 1.50) + (6 x 2)
= $18
The second customer:
= (2 x 1.50) + (2 x 9)
= $21
These tally with the amounts paid by the customers so they are the prices of the unit pound of carrots and potatoes.

pennsylvania sales tax is charged at the rate of 6%. Find the tax and the total price you would pay for an $860 TV
The sales tax will be $51.6, bringing the total cost of $860 TV to $911.6.
What do we mean by sales tax?A sales tax is a tax levied on the sale of certain goods and services and paid to a governing body. Generally, laws allow the seller to collect tax funds from the consumer at the point of purchase.A use tax is a tax on goods or services that is paid directly to a governing body by a consumer. Food, education, and medicines, for example, are frequently exempt from sales and use tax under state law. A value-added tax (VAT) on goods and services is similar to a sales tax. Key differences can be found in the comparison with sales tax.So, to find the sales tax we need to find out the 6% of $860.
= 860/100 × 6= 8.60 × 6= 51.6So, the total price will be 860 + 51.6 = $911.6Therefore, the sales tax will be $51.6 and the total price we would pay for an $860 TV will be $911.6.

2900 dollars is placed in an account with an annual interest rate of 9%. How much will be in the account after 13 years, to the nearest cent?
Answer:
$8,890.83
Step-by-step explanation:
To find the answer we have to use this equation:
[tex]A = P(1 + r)^t[/tex]
A = The total amount
P = The initial amount
R = The interest rate
T = Time
Given in the question:
A = ?
P = 2,900
R = .09
T = 13
Plug it into the equation and solve:
[tex]A = 2900(1 + .09)^1^3\\A = 2900(1.09)^1^3\\A = 2900(3.065804612)\\A = 8890.83[/tex]
Therefore, after 13 years there will be $8,890.83 in the account.
