Answer:

This is an Exponential Decay

Step-by-step explanation:

A = 1200(0.85)⁶

The above expression is an Exponential Decay because 0.85 is less than 1

The formula for Exponential Decay

= y = a (1 - r)^t

We equate both equation together

Where

a = 1200

1 - r = 0.85

t = 6

Solving for r

1 - r = 0.85

r = 1 - 0.85

r = 0.15

Converting to Percentage

r = 15% decay rate

Let me know if wrong!! :))

Step-by-step explanation:

Answer:

Step-by-step explanation:

y is inversely proportional to x; if x increases, y decreases.

Without more info it is not possible to find the constant of proportionality.  Recheck the original numerical values.  Think:  8 = kxy.  You need to know x and y to find the value of k.

Answer: $329.05

Step-by-step explanation:

Since she pays $245.82 monthly and she is paying for 6 months, the amount paid will be:

= $245.82 × 6

= $1474.92

Since she buys the full golf club set for $1,145.87, then her finance charge will be:

= $1474.92 - $1,145.87

= $329.05

The finance charge is $329.05

Answer:

[tex]x = 13.8[/tex]

Step-by-step explanation:

Given

See attachment for triangle

Required

Find x

To find y, we make use of the relationship between sides lengths 11 & x and angle 37

The relationship is:

[tex]cos(37) = \frac{11}{x}[/tex]

i.e.

[tex]cos(\theta) = \frac{Adjacent}{Hypotenuse}[/tex]

Make x the subject

[tex]x = \frac{11}{cos(37)}[/tex]

[tex]x = \frac{11}{0.7986}[/tex]

[tex]x = 13.7741[/tex]

[tex]x = 13.8[/tex] -- approximated

Answer:

Step-by-step explanation:

The square root is possible only if y≤0

if y>0 the expression lose meaning, in fact (-)(+)(+) = (-) and a square root of a negative number doesn’t exist. x^2 is a square so it is ever positive if x is not 0

if y≤0 can be rewritten as:

3(-27x^2y^7)^1/2

or if we want simplify the expression:

[tex]3 \sqrt{3^2 * (-3) * x^2 * y^6 * y} = 3^2|x||y|^3 (-3y)[/tex] ^1/2

we have to put the symbol of absolute value between x and y because a x^2 and y^6 are numbers that are ever positive, while x and y^3 can be also negative. Thanks to the simbol of absolute value we can “force” them to be positive

Answer: 9 inch

Step-by-step explanation:

Given

Distance between city A and city B is 540 miles

Scale on the map is 1 inch: 60 miles i.e. 1 inch on the map is equivalent to 60 miles in the real situation

suppose the distance between city A and B on the map is x

[tex]\therefore \dfrac{1}{60}=\dfrac{x}{540}\\\\\Rightarrow x=\dfrac{540}{60}=9\ in.[/tex]

Therefore, the distance between city A and B is 9 in.

Answer:the discount was $16.80

Step-by-step explanation:

Discount=30% of original price

=0.3X$56

=16.80

The discount was $16.80 in dollars and cents

Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.

We are given that Zachary bought some belts online for $56. He used a coupon code to get a 30% discount.

Given the website also app lied a 15% processing fee to the price after the discount.

Discount = 30% of original price

= 0.3 x $56

=16.80

Answer:

1/4x = 27

Step-by-step explanation:

Given the equations :

1.)

1/4x = 27 ;

x/4 = 27

x = 27 * 4

x = 108

2.)

3x = 36

Divide both sides by 3

x = 36/3

x = 12

3.)

3/4x = 9

3x / 4 = 9

3x = 9*4

3x = 36

x =. 36/3

x = 12

4. 4x = 48

x = 48/4

x = 12

All other equations equal to 12 except (1)

Answer:

-3/9=07+90

Step-by-step explanation:

Answer:  y = 0x+3 or y = 3

The slope is 0 and the y intercept is 3. So m = 0 and b = 3.

Plug those into y = mx+b to get y = 0x+3, and that simplifies to y = 3.

This graphs out a horizontal line that passes through the two points (0,3) and (1,3).
