<h3>
Answer: D) -3</h3>
Explanation:
Recall that y = f(x) since both are outputs of a function.
If k = 2, then f(x) = 2 leads to y = 2 being a horizontal line drawn through 2 on the y axis. This horizontal line only crosses the cubic curve at one spot. The same can be said if k = 0 and k = -2. So we can rule out choices A,B,C.
On the other hand, if k = -3, then f(x) = -3 has three different solutions. This is because the horizontal line through -3 on the y axis crosses the cubic at 3 different intersection points.
Answer:
1. 2 × 10⁵
2. 8 × 10⁴
3. 9 × 10⁸
4. 1 × 10¹⁰
Step-by-step explanation:
Answer:
u>-4
Step-by-step explanation:
muliply both sides by 2
-12< 3u
divide both sides by 3
-4<u
u>-4
V=14.4 is the answer to ur question my friend
The statement which best compare the mold growth rates is: C. the mold growth rate of the banana bread was half the mold growth rate of the whole wheat bread.
<h3>How to compare the mold growth rates?</h3>
First of all, we would determine area of mold growth B(t) on the piece of banana bread by using this equation:
B(t) = 20(1.06)^t
At t = 1, we have:
B(t) = 20(1.06)^1
B(t) = 21.2 mm².
At t = 2, we have:
B(t) = 20(1.06)^2
B(t) = 22.47 mm².
At t = 3, we have:
B(t) = 20(1.06)^3
B(t) = 23.82 mm².
At t = 4, we have:
B(t) = 20(1.06)^4
B(t) = 25.25 mm².
Now, we can compare the mold growth rates by using this expression:
B(t) = xW(t)
x = B(t)/W(t)
x = 21.2/40.8
x = 0.5.
At t = 2, we have:
x = 22.47/41.62
x = 0.5.
At t = 3, we have:
x = 23.82/42.45
x = 0.5.
At t = 4, we have:
x = 43.30/25.5
x = 0.5.
