The price of gold has increased by 35% per year from 2000. In the year 2000, Harry bought a gold ring for $590. Which of the fol

lowing equations can be used to represent the price of the ring x years after 2000?
y = 590(1.35)x
y = 590(0.65)x
y = 35(0.41)x
y = 35(1.59)x

Answer:

Option first is correct.

Step-by-step explanation:

Here cost of gold ring in 2000  was = $590

Each year increase  = 35%  

in decimals  = 0.35

therefore cost after increase will be 1+0.35 = 1.35 of initial that is

                                                 

after 2 years =   590(1.35)^2

likewise after 3 years =590(1.35)^3

Similarly after x years it will be = 590(1.35)^x

Option 1 is correct!

The zero of the polynomial 6x power 2 + 19 X - 77 is​
Iteru [2.4K]

Answer:

The zeros of the polynomial are x = 7 or x = -11/2

Step-by-step explanation:

The zeros of a polynomial refers to the solution of the polynomial.

6x^2 + 19x -77

6x^2-14x+ 33x -77

2x(x-7) + 11(x-7)

= (2x + 11)(x-7)

2x + 11 = 0

x-7 = 0

2x = -11

x = -11/2 = -5.5

and x-7 = 0

x = 7

So the zeros of the polynomial are x = 7 or x = -11/2

Mark had 14 problems wrong on his test. his score was 72% correct. how many problems were on the test?
ella [17]
Let x = number of problems on test
If he got 14 wrong, then x - 14 is the number correct.
\frac{x-14}{x} = .72

x - 14 = .72x
.28x - 14 = 0
.28x = 14
x = 50

The test consisted of 50 problems.

The number of users on a website has grown exponentially since its launch. After 2 months, there were 90 users. After 4 months,
grigory [225]

Answer:

10(3)^x

Step-by-step explanation:

The function contains the points (2,90) and (4,810). Use the general form y=abx to write two equations:

90=ab^2 and 810=ab^4

Solve each equation for a:

a=90/b^2 and a=810/b^4

Since a=a, set the other sides of the equations equal and solve for b.

90/b2=810/b4

Cross multiply, then divide and simplify as follows:

90b^4=810b^2

b^4/b^2=810/90

b^2=90

b^3

Now, use the value of b and the point (2,90) to find the value of a.

90=a(3^2)

a=10

So, substitute answers in original equation for a final answer of f(x)=10(3)^x.
