Answer:
it is 3.00
Step-by-step explanation:
as you can see first we define the variables
1. the y axis(vertical) represents the cost of peaches while the x axis (the bottom one) represents the number of pounds
2. then we find a place where the line crosses the grid but exactly on the corner of the box
3. when we have found our point which is (2,6) it means that every 2 pounds of peaches is 6 dollars
4. divide 6/2 and you get 3 dollars!
Answer: The amount of carbon-14 remaining after 4 years is 99.95 grams.
Step-by-step explanation:
Hi, to answer this question we simply have to substitute t=4 in the equation given and solve for c.
c= 100 (0.99988)^t
c =100 (0.99988)^4
c = 100 x 0.999520086
c= 99.95200864 ≅99.95 grams (rounded)
The amount of carbon-14 remaining after 4 years is 99.95 grams.

<u>ANSWER: </u>
x-intercepts of 
<u>SOLUTION:</u>
Given,
-- eqn 1
x-intercepts of the function are the points where function touches the x-axis, which means they are zeroes of the function.
Now, let us find the zeroes using quadratic formula for f(x) = 0.

Here, for (1) a = 1, b= 12 and c = 24


Hence the x-intercepts of 
Answer:
9x^4-25x^2+16
Step-by-step explanation:
(x^2−1)(3x−4)(3x+4)=(*)
(x^2−1)((3x)^2−4^2) =
(x^2 - 1)(9x^2-16)=
x^2*9x^2 - x^2*16 - 1*9x^2 +16=
9x^4-16x^2-9x^2+16=
9x^4-25x^2+16
(*) (A-B)(A+B) =A^2 - B^2
