Answer:

$119520

Step-by-step explanation:

Given: Purchase price of Diamond ring= $12000

Value of ring increase by 32% each year.

First finding number of year between 2012 and 2040, to know the time period of value appreciation.

Time period= $2040-2012= 28\ years$

∴ Time period of value appreciation is 28 years.

Now, finding the value of diamond ring increased after 28 years.

Value of ring increased after 28 years= $\frac{12000\times 32\times 28}{100}$

∴ Increased value of diamond ring after 28 years= $107520

Next, Value of diamond ring after 28 years= $12000+107520= \$ 119520$

Hence, value of diamond ring in 2040 is $119520

One x-intercept for a parabola is at the point (1,0). Use the factor method to find the other x-intercept for the parabola defin

Hoochie [10]

First simplify the equation of parabola $y=-5x^2+15x-10$ in the following way:
$D=(15)^2-4\cdot (-5) \cdot (-10)=225-200=25, \\ \sqrt{D}=5, \\ x_{1,2} = \dfrac{-15\pm 5}{2\cdot(-5)} = 2, 1 \\ -5x^2+15x-10=-5(x-1)(x-2), \\ y=-5(x-1)(x-2)$ .
You can see that if x=1 or x=2, then y=0. Two points of intersection with x-axis are (1,0) and (2,0).

Hi if u could help me that'd be great

WINSTONCH [101]

Answer:

1 hour and 45 minutes

and 1 hour

Step-by-step explanation:

x= run

y= walk

5x+2.5y = distance

5x+2.5(1.5)=12.5

solve for x

5x=8.75

x=1.75

1.75 in hours is 1 hour and (60*.75)=45

1 hour and 45 minutes

" If the marathon race participant ran for 2 hours, how many hours did the participant walk?"

We use the same equation

5x+2.5y=distance

we'll assume that they till walked 12.5 miles

which means that

5(2)+2.5y=12.5

solve for y

2.5=2.5y

y=1

1 hour

You have two nickels three dimes and a quarter. Using at least one of each coin, how many different amounts of money can you mak

Slav-nsk [51]

2 nickels (5 cents each)
3 dimes (10 cents each)
1 quarter (25 cents)

1 nickel, 1 dime, 1 quarter
5 + 10 + 25 = 40

2 nickels, 1 dime, 1 quarter
5(2) + 10 + 25 = 45

1 nickel, 2 dimes, 1 quarter
5 + 10(2) + 25 = 50

1 nickel, 3 dimes, 1 quarter
5 + 10(3) + 25 = 60

2 nickels, 2 dimes, 1 quarter
5(2) + 10(2) + 25 = 55

2 nickels, 3 dimes, 1 quarter
5(2) + 10(3) + 25 = 65

You can make 6 different amounts.
You could also find this by multiplying however many coins you have all together.
2 * 3 * 1 = 6

If the diameter of circle a measures half of the diameter of circle b, then the area of circle b is how many times the area of c

Eduardwww [97]

Circle b:

Diameter = x

Radius = $\frac{x}{2}$

Area = $\pi r^{2} = \pi ( \frac{x}{2} )^{2} = \frac{ \pi x^{2} }{4}$

Circle a:

Diameter = $\frac{x}{2}$

Radius = $\frac{x}{2} * \frac{1}{2} = \frac{x}{4}$

Area = $\pi r^{2} = \pi ( \frac{x}{4} )^{2} = \frac{ \pi x^{2} }{16}$

Thus,

Area of circle b to area of circle a

= $\frac{ \pi x^{2} }{4}$ ÷ $\frac{ \pi x^{2} }{16}$

= $\frac{ \pi x^{2} }{4}$ × $\frac{ 16 }{\pi x^{2}}$

= 4

Hence, the area of circle b is 4 times the area of circle a.

Match the following items by evaluating the expression for x = -2.

Sloan [31]

Answer:

1) $-4$

2) $-3$

3) $1$

4) $-2$

5) $4$

Step-by-step explanation:

According to the information given in the exercise, the value of "x" is:

$x = -2$

Then:

1) You must substitute $x = -2$ into the expresion $x-2$ :

$=(-2)-2$

Now, you must evaluate:

$=-4$

2) You have to substitute the given value of "x" into the second expression:

$x-1=(-2)-1$

Finally, evaluating, you get the following result:

$=-3$

3) According to the Zero exponent Rule, any non-zero number with an exponent of zero is equal to 1.

Then, substituting $x = -2$ into the expression $x^0$ and then evaluating, you get:

$x^0=(-2)^0=1$

4) By definition:

$a^1=a$

Then, substituting $x = -2$ into $x^1$ and evaluating, you get:

$x^1=(-2)^1=-2$

5) Since:

$a^2=a*a$

When you substitute the given value of "x" into the last expression and then you evaluate, you get:

$x^2=(-2)^2=(-2)(-2)=4$
