An Impressionist painting increases in value

Answer:

A = $8406.6

Step-by-step explanation:

Given:

Average rate r=9\%

Initial cost of painting a = \$1500

Time t = 20\ years

We need to find the final amount of painting at the end of a 20-year.

Solution:

Using Exponential Growth rate formula as:

A = a(1+r)^t  ----------(1)

Where:

A = Final amount

a = Initial amount.

r = Rate as a decimal.

t = Time.

Now, we substitute all given values in equation 1.

A = 1500(1+0.09)^{20}

A = 1500(1.09)^{20}

Substitute 1.09^{20} = 5.60 in above equation.

A = 1500\times 5.60

A = $8406.62

Therefore, value of the  painting at the end of  a 20-year A = $8406.6

Solve for x: 3√5x² +25x-10√√5 = 0
bogdanovich [222]

Answer:  x = - 2√5, √5/3

Step-by-step explantion

3 √ 5 x 2 + 25 x − 10 √ 5 = 0 35x2+25x−105=0

⇒ 3√5x2 + 30x – 5x – 10√5 = 0  

⇒ 3√5x(x + 2√5) – 5(x + 2√5) = 0  

⇒ (x + 2√5)(3√5x – 5) = 0

x = - 2√5, √5/3

A point is reflected over the y-axis to graph a new point. Are the x-coordinates of these points opposite of each other? Hewp!
musickatia [10]
Well let's say you have a coordinate (2, -1)

Now if we reflect it upon the y-axis we'll end up at the coordinate (2,1)

We see that the x value is still the same.
