Answer:

5%

Step-by-step explanation:

4000 × 9 × r = 1800

r = 1800/36000

r = 0.05 × 100

Answer:

9% or 0.09

Step-by-step explanation:

so 1800/4000 is .45 then we do .45/5 which is 0.09 and if u wanna double check do 4000 x 0.09 then that gives us 360 then we do 360 x 5 for 5 years that you've been investing which leaves us with 1800 which is the interest you got.

Find the x-intercept of the function f(x) = a^x + 1 - 1.
babymother [125]

I am not certain of what you wrote for the function but will assume that is likely exponential function or quadratic function.

First, (quadratic function) To solve this, you must know the quadratic formula. The x-intercept is value(s) that has the output value(y) of 0.

If the vertex of the quadratic function of (0,0), there is only one x-intercept. The number and value of the x-intercept depends on the slope and vertical displacement.

Second, (exponential function) note that there is no x-intercept. For instance, if a is 2, is there such value y that 2^y is 0? The smallest exponential value that is an integer is 1. Even broadening the limit to rational numbers, no such exponential value can have the result of 0. Therefore, in the basic form of exponential function, there is no x-intercept.
