Find the first three terms of the sequence below.
Tn = n2 + 5n + 2
Step-by-step explanation:
T1 = 1^2 + 5(1) + 2 = 8
T2 = 2^2 + 5(2) + 2 = 16
T3 = 3^2 + 5(3) + 2 = 26

Answer:
First three terms : 8 , 16 , 26
Step-by-step explanation:
[tex]T_{n}=n^{2}+5n + 2[/tex]
n = 1 , [tex]T_{1}=1^{2}+5*1+2=1+5+2 = 8[/tex]
n = 2 , [tex]T_{2}=2^{2}+5*2+2 = 4+10+2 = 16[/tex]
n= 3, [tex]T_{3} = 3^{2}+5*3+2=9+15+2 = 26[/tex]
Which expression is equivalent to 4k+2k?
Answer:
it equals 6k but an equivalent expression could be 2k + 4k
Step-by-step explanation:
2k + 4k = 4k + 2k
Answer:
6k
Step-by-step explanation:
You can combine both of these terms because they both have the same variable (k). We know that 4+2=6, and the variable stays the same, 6k.

A cylinder has a diameter of 18 centimeters. The length of the curved surface is
centimeters
Answer:
180πcm²
Step-by-step explanation:
The formula for calculating curved surface area of a cylinder is
CSA=2πrh
r I the radius= 18cm/2 = 9cm
Let the height be 19cm
CSA = 2π(9)(10)
CSA = 180πcm²
Hence the length of the curved surface area is 180πcm²
Note that the height of the cylinder was assumed

The bearing of Lakeshore from Klayton is 196°. What is the bearing of Klayton from Lakeshore
Answer:
9 pieces
Step-by-step explanation:
first convert 40cm to m by dividing by 100cm
then divide 3.6m by 0.4 then the ans will come.
A) There are 9 strings each of length of 40 cm.
B) 0.20, 5/12, 75% is already in the ascending order.
C) The bearing of Klayton from Lakeshore is also 196°.
In mathematics, it deals with numbers of operations according to the statements.
A) A 3.6 m long string is to be cut into pieces, each of length 40 cm.
3.6 m = 3.6 * 100cm
3.6 m = 360 cm
Let the number of stings be x
x * 40 = 360
x = 360 / 40
x = 9
there are 9 strings each of length of 40 cm.
Arranging the following in ascending order of magnitude: 0.20, 5/12, 75%
0.20, 5/12, 75% is already in the ascending order.
The bearing of Lakeshore from Klayton is 196°. The bearing of Klayton from Lakeshore is also 196°.
Thus, the answers to the given problem are calculated above.

The temperature of a cooling cup of coffee can be modelled by the equation
T = 90(0.94)", where T represents the temperature of the coffee and n is the
number of hours since it was poured. Explian what 90 and 0.94 represent in
this equation.
Answer:
See below
Step-by-step explanation:
I assume the " is n.
90 is your initial/starting temperature, in other words when n = 0 hours, the temperature will be 90.
The 0.94 part shows the rate of exponential decay.

Answer:
Side length: 28
Area: 784
Step-by-step explanation:
Pythagorean
Hope This helps
Answer:
Side lengths of the square are 10 units. The area of the square is 100 units squared
Step-by-step explanation:
Use the Pythagorean theorem to find the hypotenuse of the right triangles. The lengths of the hypotenuses is the same as the side lengths of the square. Since it's a square all the sides are congruent(same length) To find the area of the square multiply the base times the height(10x10) because it's a square the area is squared. Therefore, the area is 100 units squared.

Screen-printing a batch of shirts requires 3 minutes per shirt in addition to 19.87 minutes of initial set-up time. How long does it take to screen-print a batch of 143 shirts? Write and solve an equation to find the answer.
Answer:
So the equation and solution will be:
Total time taken = 3 × number of shirts + 19.87 min (setup time)
= 3 × 143 + 19.87
[tex]=429+19.87[/tex]
[tex]=448.87[/tex]
Step-by-step explanation:
From the question statement, it is clear that
screen-printing a batch of shirts requires 3 minutes per shirt in addition to 19.87 minutes of initial set-up time.we have to determine how long does it take to screen-print a batch of 143 shirts.
so the equation and solution will be:
Total time taken = 3 × number of shirts + 19.87 min (setup time)
= 3 × 143 + 19.87

3 to the second power is 9
because three times three is 9
Answer:
9
Step-by-step explanation:
Do the numbers inside of the parenthesis first because of PEMDAS (parenthesis, exponents, multiplication, division, addition, subtraction). Then, you will get 36. Divide this by 6, the next step using PEMDAS. You will get 6. Now finally, subtract 3. Now you have 3. Now, what is 3 to the power of 2? Well simply multiply 3 by itself. You have the answer of 9 at this point.

Answer:
[tex]d = \frac{4 - 3c}{c + 1} [/tex]
Step-by-step explanation:
To make d the subject of formula, we need to rearrange the equation such that we arrive at d= _____.
[tex]c = \frac{4 - d}{d + 3} [/tex]
Remove the fraction by multiplying (d +3) on both sides:
[tex]c(d + 3) = 4 - d[/tex]
Expand:
[tex]cd + 3c = 4 - d[/tex]
Bring all the d terms to one side and move the others to the other side of the equation:
[tex]cd + d = 4 - 3c[/tex]
Factorise d out:
[tex]d(c + 1) = 4 - 3c[/tex]
Divide by (c +1) on both sides:
[tex]d = \frac{4 - 3c}{c + 1} [/tex]

Find the distance from point A(−14, 5) to the line −x+2y = 14.
Answer:
The distance from point A to given line is: 2√5 or 4.472 units
Step-by-step explanation:
Given equation of line is:
[tex]-x+2y= 14[/tex]
And the point is:
[tex]A = (x_1,y_1) = (-14,5)[/tex]
The standard form of equation of line is:
[tex]Ax+By+C = 0[/tex]
Converting the given equation into standard form
[tex]-x+2y-14=0[/tex]
The distance of a point (x1,y1) from a line is given by the formula:
[tex]d = \frac{|Ax_1+By_1+C}{\sqrt{A^2+B^2}}[/tex]
In the given details,
A = -1, B = 2, C = -14
x1 = -14, y1 = 5
Putting the values in the formula
[tex]d = \frac{|(-1)(-14)+(2)(5)-14|}{\sqrt{(-1)^2+(2)^2}}\\d = \frac{14+10-14}{\sqrt{1+4}}\\d = \frac{10}{\sqrt{5}}\\d = \frac{5*2}{\sqrt{5}}\\d = \frac{\sqrt{5}*\sqrt{5}*2}{\sqrt{5}}\\d = 2\sqrt{5}\\d = 4.472\ units[/tex]
Hence,
The distance from point A to given line is: 2√5 or 4.472 units
Brian bought two shirts for $14.50 each and a pair for shoes for $29.99.the sales tax was 6%.how much did Brian spend?
Answer:
Brian spent 62.5294 $.
Step-by-step explanation:
The cost of two shirts = [tex]2\times \:14.5=29[/tex] $
The cost of 1 pair of shoes = [tex]1\times 29.99\:[/tex] = [tex]29.99[/tex] $
Adding the calculated costs = [tex]29+29.99=58.99[/tex] $Tax calculation:
[tex]\frac{6}{100}\times \:58.99=3.5394[/tex] $Now, adding calculated costs and tax calculation:
58.99$ + 3.5394$ = 62.5294 $
Therefore, Brian spent 62.5294 $.
If the spinner lands on green 10 times out of 60 spins, which statement is true?
The spinner lands on green 5 more times than expected.
The spinner lands on green 5 less times than expected.
The spinner lands on green 2 more times than expected
The spinner lands on green 2 less times than expected.
Answer: The spinner lands on green 5 less times than expected.
Step-by-step explanation:
Assuming the spinner has 4 colors, the chance of it landing on green will be 25%.
If there are 60 spins, the expected number of times it should land on green is;
= 60 * 25%
= 15 times
It only landed on green 10 times which is 5 less times than expected.
