A social media website had 350,000 followers in 2010. The number y of followers
increases by 2% each year.
a. Write an exponential growth function that represents the number of followers t
years after 2010
b. How many people will be following the website in 2016? Round your answer to the
nearest thousand.
Answer:
a) [tex]y(t) = 350(1.02)^t[/tex]
b) 394 thousand = 394,000 people will be following the website in 2016
Step-by-step explanation:
Exponential equation for an amount:
The exponential equation for an amount after t years has the following format:
[tex]y = y(0)(1+r)^t[/tex]
In which y(0) is the initial value and r is the growth rate, as a decimal.
A social media website had 350,000 followers in 2010. The number y of followers increases by 2% each year.
This means that: [tex]y(0) = 350, r = 0.02[/tex]
a. Write an exponential growth function that represents the number of followers t years after 2010
In thousands:
[tex]y(t) = 350(1 + 0.02)^t[/tex]
[tex]y(t) = 350(1.02)^t[/tex]
b. How many people will be following the website in 2016?
2016 is 6 years after 2010, so this is y(6).
[tex]y(6) = 350(1.02)^6 = 394.2[/tex]
Rounding to the nearest thousand:
394 thousand = 394,000 people will be following the website in 2016

simone buys a painting for 24000 later she sells it for 60000 how much is her percentage profit
Answer:
percentage profit = 150%
Step-by-step explanation:
percentage profit = sp - cp/cp * 100
sp is the selling price = 60000
cp is the cost price = 24000
percentage profit = 60000-24000/24000 * 100
percentage profit = 36000/24000 * 100
percentage profit = 36000/240
percentage profit = 150%

The equation of a circle is a measure of its center and its radius.
The equation of the circle is: [tex]x^2 + y^2 - 14x -8y + 56 = 0[/tex]
The general equation of a circle is [tex](x - a)^2 + (y - b)^2 + r^2[/tex]. Where:
[tex](a,b) \to[/tex] center
[tex]r \to[/tex] radius
From the given figure, we have:
[tex]r = 3[/tex]
[tex](a,b) = (7,4)[/tex]
So, the equation of the circle is:
[tex](x - a)^2 + (y - b)^2 + r^2[/tex]
[tex](x - 7)^2 + (y - 4)^2 = 3^2[/tex]
[tex](x - 7)^2 + (y - 4)^2 = 9[/tex]
Open brackets
[tex]x^2 - 14x + 49 + y^2 -8y + 16 = 9[/tex]
Collect like terms
[tex]x^2 + y^2 - 14x -8y + 49 + 16 - 9 = 0[/tex]
[tex]x^2 + y^2 - 14x -8y + 56 = 0[/tex]
Hence, the equation of the given circle is: [tex]x^2 + y^2 - 14x -8y + 56 = 0[/tex]

Write an explicit formula for An, the nth term of the sequence 6, 18, 54, ....
Answer:
[tex] a_{n} = (6){3}^{n - 1} [/tex]
Step-by-step explanation:
6, 18, 54
First, recognize that this is a geometric sequence. To find the common ratio, divide the f
second term by the first term.
18/6 = 3
Check this with the second and third term.
54/18 = 3
Your common ratio is 3.
An explicit formula for a geometric equation is:
[tex] a_{n} = a_{1} {r}^{n - 1} [/tex]
We know the first term is 6 and the common ratio is 3. Plug in these values.
[tex] a_{n} = (6) {3}^{n - 1} [/tex]
This is your formula.
Hope this helps!

3(5x - 6) = 6(2x - 12)
Answer:
x = -18
Step-by-step explanation:
Distribute: 3*5x = 15x ; 3*-6 = -18 ; 6*2x = 12x ; 6*-12 = -72
15x - 18 = 12x - 72
Add 18 to both sides: 15x = 12x - 54
Subtract 12x from both sides: 3x = -54
Divide both sides by 3: x = -18
Answer:
x= 17.666666...
Step-by-step explanation:
3(5x - 6) = 6(2x - 12)
(3 times 5x , 3 times -6) (6 times 2x, 6 times - 12)
15x-18 = 12x -72 (multiply insides)
-12x -12x (remove 12x from right side)
3x-19 = -72 (product)
+19 = +19 (add 19 left side to remove it)
3x = 53 (product)
x = [tex]\frac{53}{3}[/tex] (divide)
x= 17.666666... (answer)
x = 17.67 (if simplify)

Simplify each of the following:
Answer:
1. x⁴³/³⁵
2. 1/x⁶
3. x⁴/2
Step-by-step explanation:
1. ⁷√x³. ⁵√x⁴
The above expression can be simplified as follow:
Recall:
ᵐ√aⁿ = aⁿ/ᵐ
⁷√x³ × ⁵√x⁴ = x³/⁷ × x⁴/⁵
Recall:
aⁿ × aᵐ = aⁿ⁺ᵐ
x³/⁷ × x⁴/⁵ = x⁽³/⁷ ⁺ ⁴/⁵⁾ = x⁴³/³⁵
Therefore,
⁷√x³. ⁵√x⁴ = x⁴³/³⁵
2. x¯³ / x⁵x¯²
The above expression can be simplified as follow:
Recall:
aⁿ × aᵐ = aⁿ⁺ᵐ
x⁵x¯² = x⁵ ⁺ ⁽¯²⁾ = x⁵ ¯ ² = x³
Thus,
x¯³ / x⁵x¯² = x¯³ / x³
Recall:
aⁿ / aᵐ = aⁿ ¯ ᵐ
x¯³ / x³ = x¯³ ¯ ³ = x¯⁶
Recall
a¯ⁿ = 1/aⁿ
x¯⁶ = 1/x⁶
Therefore,
x¯³ / x⁵x¯² = 1/x⁶
3. 5(x⁴)³ / 10x⁸
The above expression can be simplified as follow:
Recall:
(aⁿ)ᵐ = aⁿ×ᵐ
5(x⁴)³ / 10x⁸ = 5x¹² / 10x⁸
Recall:
aⁿ / aᵐ = aⁿ ¯ ᵐ
5x¹² / 10x⁸ = (5/10)x¹² ¯ ⁸ = 1/2 x⁴ = x⁴/2
Therefore,
5(x⁴)³ / 10x⁸ = x⁴/2
