The absolute value of -15 is 15, because -15 is 15 away from zero
answer:
-167
Step-by-step explanation:
if x=-6 you use the equation with -6 for x, 27 times -6 is -162, -162-5 is -167.
Answer:
The value of function (fog)(x) is 4 x² - 19
Step-by-step explanation:
Given function as :
f(x) = 4 x + 1
g(x) = x² - 5
So , function (fg(x)) can be written as
(fog)(x) = 4 ( x² - 5 ) + 1
Or, (fog)(x) = 4 x² - 20 + 1
Or, (fog)(x) = 4 x² - 19
Hence The value of function (fog)(x) is 4 x² - 19 Answer
Answer:
Two figures that have both line symmetry and rotational symmetry are: Circle and square
Answer:
There are 2,000 grams left after 300 years.
Step-by-step explanation:
Giving the following information:
The half-life of a radioactive substance is 200 years. There are 8000 grams of the substance initially.
<u>First, we need to calculate the reduction of the substance each year:</u>
Yearly reduction= 8,000/400= 20 grams per year
<u>Now, for 300 years:</u>
300 year reduction= 20*300= 6,000
There are 2,000 grams left after 300 years.
