Answer:
A
Step-by-step explanation:
i took the test
4.75/0.25=19
200*19=3800
It will take Tammy 3800 steps
Jack is 32 and lacey is 16 because 54-6 (3 years for each person) is 48. 48 divided by 3 is 16 and 32 is double 16
The given function can also be written in the
form:
f (x) = 15 (1 + 1)^x
Where this equation is similar to the general
growth rate equation:
f (x) = k (1 + i)^n
Where,
i = percent rate of growth
n = number of years
Since we want to set that n = x/2, therefore we
need to find the new i. We can do this by equating the two:
<span>(1 + i)^x/2 = (2)^x</span>
Multiplying the exponents of both sides by 1/x:
(1 + i)^1/2 = 2
1 + i = 4
i = 3
Therefore the new equation is:
f (x) = 15 (4)^(x/2)
or
<span>f (x) = 15 (2^2)^(x/2) (ANSWER)</span>
<span> </span>
Answer:
5x - y = - 2
Step-by-step explanation:
The equation of a line in standard form is
Ax + By = C ( A is a positive integer and B, C are integers )
First obtain the equation in slope- intercept form
y = mx + c ( m is the slope and c the y- intercept )
here m = 5 and the line passes through (0, 2) ⇒ c = 2
y = 5x + 2 ← in slope- intercept form
Subtract y from both sides
0 = 5x - y + 2 ( subtract 2 from both sides )
5x - y = - 2 ← in standard form
