The function of correct growth or decay factors are,

[tex]y = (0.3) (0.5)^{x}[/tex] is an exponential decay factor of 50%.

[tex]y = 2000(\frac{4}{5} )^{x}[/tex] is an exponential decay factor of 15%.

[tex]y = 800 (1.15)^{x}[/tex] is an not exponential decay factor related to growth factor 15%.

[tex]y = 1200 (1.05)^{x}[/tex] is an not exponential decay factor related to growth factor 5%.

[tex]y = 3(0.85)^{x}[/tex] is an exponential decay factor of 85%, then the related to  20%.

We know that,

Exponential Decaying factor is [tex]y = ab^{x}[/tex]

Where, 0<b<1

The decay rate is expressed as a percentage. We convert it to a decimal by simply reducing the percent and dividing it by 100.

Growth factor is the factor by which a quantity multiplies itself over time. Growth rate is the addend by which a quantity increases (or decreases) over time.

Here,

Option(1) : [tex]y = (0.3)(0.5)^{x}[/tex]

Then,  0.5 < 1        (0.5 means 50%)

So, [tex]y = (0.3) (0.5)^{x}[/tex] is an exponential decay factor .

Hence,  [tex]y = (0.3) (0.5)^{x}[/tex] is an exponential decay factor of 50%.

Option(2) : [tex]y = 2000(\frac{4}{5}) ^{x}[/tex]

Then,  4/5 < 1

⇒ 0.8 < 1

So, [tex]y = 2000(\frac{4}{5} )^{x}[/tex] is an exponential decay factor.

Hence, [tex]y = 2000(\frac{4}{5} )^{x}[/tex] is an exponential decay factor of 15%.

Option(3) : [tex]y = 800 (1.15)^{x}[/tex]

Then,  1.15 > 1

So, [tex]y = 800 (1.15)^{x}[/tex] is an not exponential decay factor.

Hence, [tex]y = 800 (1.15)^{x}[/tex] is an not exponential decay factor of 115%, so it is not decay factor, then the related to growth factor 15%.

Option(4) : [tex]y = 1200 (1.05)^{x}[/tex]

Then,  1.05 > 1

So, [tex]y = 1200 (1.05)^{x}[/tex] is an not exponential decay factor.

Hence, [tex]y = 1200 (1.05)^{x}[/tex] is an not exponential decay factor of 105%, so it is not decay factor, then the related to growth factor 5%.

Option(5) : [tex]y = 3(0.85)^{x}[/tex]

Then,  0.85 < 1

So, [tex]y = 3(0.85)^{x}[/tex] is an exponential decay factor.

Hence, [tex]y = 3(0.85)^{x}[/tex] is an exponential decay factor of 85%, then the related to  20%.

Therefore,

[tex]y = (0.3) (0.5)^{x}[/tex] is an exponential decay factor of 50%.

[tex]y = 2000(\frac{4}{5} )^{x}[/tex] is an exponential decay factor of 15%.

[tex]y = 800 (1.15)^{x}[/tex] is an not exponential decay factor related to growth factor 15%.

[tex]y = 1200 (1.05)^{x}[/tex] is an not exponential decay factor related to growth factor 5%.

[tex]y = 3(0.85)^{x}[/tex] is an exponential decay factor of 85%, then the related to  20%.

Answer: t = 6/11

Step-by-step explanation:

3t - 2 + t = 4 - 7t

4t - 2 = 4 - 7t

4t + 7t = 4 + 2

11t = 4 + 2

11t = 6

Divide both by 11

Answer : t = 6/11

Answer:

t = 6/11

Step-by-step explanation:

Hello!

Solve the equation for t by isolating the variable.

The value for t is 6/11.

The value of the expression below when x=5x=5?

8x+9 is equal to [tex]7^{2}[/tex] (or) 49.

Substitute [tex]\left \{ {{x=5x} \atop {5x=5}} \right. into (8x+9)[/tex]

The expression,

y = 8x + 9

If the domain of the function is x = 5, hence the range of the function is gotten by substituting x = 5 into the given function as shown:

So, we can substitute x = 5,

Then, y = 8 * 5 + 9

Calculate the product or quotient,

y = 40 + 9

Calculate the sum or difference,

y = 49

We can write alternative form,

y = [tex]7^{2}[/tex]

Therefore,

Hence the value of the expressions if x = 5 is [tex]7^{2}[/tex] (or) 49.

Answer: a. h=3V/(πr^2)

b. h=27 inches

Step-by-step explanation:

a. V=1/3 π r^2 h

V*3=3*1/3 π r^2 h

3V=3/3 π r^2 h

3V=π r^2 h

3V/π=π/π r^2 h

3V/π=r^2 h

h=3V/(πr^2)

b. h=3(1017.36)/(3.14(6^2))

A line that bisects or cuts an objects into two equals parts is called the axis of symmetry for that object. The axis of symmetry creates a mirror-like reflection of each side of the object.

The function f(x) = |x| is called an absolute value function. The highest or lowest point on the graph of the absolute value function is called the vertex. The absolute value graph has an axis of symmetry through the vertices.

The axis of symmetry (x=0 or y-axis) is the line that divides the graph into two congruent halves. Translate is a transformation that moves the graph horizontally or vertically, but does not change its overall shape or orientation.

Based on the total amount that Karen spent in one week at the Starbucks, the cost of one latte was $6.83

Karen left a tip of a dollar every day she bought a Latte so this comes to:

= 1 x 5 days

= $5

The cost of a single latte is therefore:

= (Total amount spent - Total tips) / Number of days

= (39.15 - 5) / 5

= 34.15 / 5
