Jesslyn hypothesizes that the value of antique furniture can be modeled by exponential decay and that the value of a particular

piece will decrease at a rate of 0.15% each year. If the furniture was originally valued at $15,000 in 1990 what should Jesslyn expect the value of the furniture to be in 2010?

If this can be modelled by exponential decay, therefore the function must be in the form of:

A = Ao (1 + r)^t

where A is the final value, Ao is the initial = 15000, r is the rate of decay = -0.0015, t is time = 2010 – 1990 = 20

 

A = 15,000 (1 – 0.0015)^20

A = $14,556.36

0.5a − 0.3 = 5 (solve for a)
Alla [95]
0.5a - 0.3 = 5

Add 0.3 to both sides:

0.5a = 5.3

Divide both sides by 0.5:

a = 10.6

A triangle has side lengths measuring 2x + 2 ft, x + 3 ft, and n ft.
brilliants [131]

Answer:

The correct option is A. x – 1 < n < 3x + 5

Step-by-step explanation:

In a triangle sum of any two sides is always greater than the third side.

Now, the sides of the triangle are given to be :

2x + 2, x + 3 , n

Now, first take 2x + 2 and x + 3 as two sides and the side of length n as third side.

By using the property that sum of two sides is always greater than the third side in a triangle.

⇒ 2x + 2 + x + 3 > n

⇒ 3x + 5 > n  ......(1)

Now, take n and x + 3 as two sides and the side of length 2x + 2 as the third side of triangle.

So, by the property, we have :

n + x + 3 > 2x + 2

⇒ n > x - 1 ...........(2)

From both the equations (1) and (2) , We get :

x – 1 < n < 3x + 5

Therefore, The correct option is A. x – 1 < n < 3x + 5

What is the y-intercept of the function f(x) = 2x – 3 + 6? <br> Round to two decimal places.
valina [46]
Y-intercept is where the graph intercepts/crosses the y-axis. So where x = 0
f(0) = 2(0) - 3 + 6
f(0) = 0 + 3
f(0) = 3
y intercept is 3
two decimal places, just add zeros
= 3.00

Karim's dog weighs 1.5 pounds less than double the weight to Frank's dog. Karim's dog weighs 15 pounds. Which equation and solut
Radda [10]
1. Because

info given:
Karim's dog = 15 pounds
Frank dog = 2x more pounds than Karim's dog + 1.5 pounds

(Karim) Equation 1: 15 = Frank
(Frank) Equation 2: 2w + 1.5

joining equation 1 and 2

15 = 2w + 1.5

Solve

15 - 1.5 = 2w
13.5 = 2w ÷ 2
w = 6.75
