Joey opened a bank account 5 years ago with $100. today he has $1000 in the account. what is the percentage od increase?

1 answer:

7 0

To calculate the percentage increase:

First: Find out the difference (increase) between the two numbers you are comparing.
It is computed by: Increase = New Number - Original Number

Second: Divide the increase by the original number and multiply the answer by 100.
It is computed by: % increase = Increase ÷ Original Number × 100.

So in the problem:
First step:Increase = 1000 – 100
Increase = 900

Second:
% increase = 900 / 100 x 100%
increase = 900% increase

>>>>>>>>> Use graphs and tables to find the limit and identify any vertical asymptotes of the functio

Fiesta28 [93]

Answer:

Step-by-step explanation:

as you can see something amazing happens in 10 in this function . If you replace x with 10 you get 1/0 wich an indetermined form in Mathematics.

Now we are sure that there is a vertical asymptote in 10. Let's see identify the limit in the left of 10.

let's assign some values to x that are smaller than 10.

1. x=9

1/(9-10)= -1

a negative value

2. x=8

1/(8-10)= -1/2

a negative value

let try a reallu colse value to 10 like 9.99

1/(9.99-10)=-100

a negative value

so we can deduce that the limit is -∞

lim [1/(x-10)]=-∞

x→10-

Rectangle EFGH is similar to rectangle JKLM. Which proportion can be used to

Dominik [7]

*See attached picture for the diagrams being referred to

Answer:

C. ⁵/12= ²/x

Step-by-step Explanation:

Given that rectangle EFGH is similar to rectangle JKLM, it means the corresponding sides of both rectangles are similar, and as such the ratios if the corresponding sides of rectangle EFGH and rectangle JKLM would be equal.

Thus, EF/JK = FG/KL

Since, EF = 5; JK = 12; FG = 2; and KL= x, therefore, the proportion to use in finding x would be:

⁵/12= ²/x

Write an equation of a line containing (2, -3) and perpendicular to 3x+4y=14 answer

Sergio039 [100]

Answer:

Step-by-step explanation:

From the condition of perpendicularity, if two lines must be perpendicular to each other, the product of their gradient rather the slope must be equaled to ( -1 ).

Equation of a line ; y = mx+ c, where m1 is the gradient of the line and c us the point of intersection if the line on the y- axis.therefore, the equation

3x + 4y = 14, when re arranged, now becomes, 4y = -3x + 14, divide through by 4, gives, y = -3x/4 + 14.

Therefore, m1, = -3/4 and m2, = 4/3 going by the condition. Since the line passes through the coordinate of (2,3), where x = 2, and y = -3, then, substitute for x and y in y = mx+ c, minding the m2, to find C, therefore,

-3 = 4/3x2 + c. -3 = 8/3 +c

Multiply through by 3 to make it a linear equation,

-9 = 8 + 3c; -9 - 8 = 3c, -17= 3c

c = -17/3.Now substitute for c in the equation ,y = mx+ c, the equation now becomes, y = 4x/3 - 17/3. Therefore the new equation is

3y = -4x - 17.
