Answer:
6.8 x 10^-3
Step-by-step explanation:
Answer:
59
Step-by-step explanation:
Round 59.3506494 to the first 2 sig figs which is 59 since the number next to the decimal isnt over or 5, so it stays as 59 instead of 60.
Answer:, x ≠ -1/4
Explanation:We are given that:
f (x) = 4x + 1
g(x) = x² - 5
We want to find the value of (g/f)(x). This means that we will simply divide g(x) by f(x) as follows:
Now, we should note that any function is undefined if its denominator is equal to zero.
This means that for our current function:
4x + 1 cannot be equal to zero
4x + 1 = 0
4x = -1
x = -1/4
This means that the value of x cannot be -1/4, otherwise, our function would be undefined.
Based on the above, the last option is the correct one.
Hope this helps :)
We have 20% and 70% salt solutions.
We need 9 liters of 50% salt solution.
"t" is liters of twenty % solution "s" is liters of seventy % solution
A) t + s = 9
B) .2t + .7s = (.5 * 9)
Multiplying A) by -.2
A) -.2t + -.2s = -1.8 Adding that to B)
B) .2t + .7s = (.5 * 9)
.5s = 2.7
s = 5.4 liters of 70% salt
A) t + 5.4 = 9
t = 3.6 liters of 20% salt

Answer:
1. V(12) = $ 1200
2. V(20) = $ 4800
Step-by-step explanation:
The following data were obtained from the question:
V(t) = 150 × 2ᵗ/⁴
V(12) =?
V(20) =?
1. Determination of V(12)
Time (t) = 12 years
V(12) =?
V(t) = 150 × 2ᵗ/⁴
V(12) = 150 × 2¹²/⁴
V(12) = 150 × 2³
V(12) = 150 × 8
V(12) = $ 1200
2. Determination of V(20)
Time (t) = 20 years
V(20) =?
V(t) = 150 × 2ᵗ/⁴
V(20) = 150 × 2²⁰/⁴
V(20) = 150 × 2⁵
V(20) = 150 × 32
V(20) = $ 4800
