Answer:
- A) k = 18.75
- B) R(0.8) = 161419
- C) R(0.3) = 275
Step-by-step explanation:
<u>Given expression</u>
A) <u>Given</u>
<u>Solving for k</u>
- 10 = 6*e^(0.04k)
- e^(0.04k) = 10/6
- ln (e^0.04k) = ln (1.6666)
- 0.04k = 0.51
- k = 0.51/0.04
- k = 12.75
B) <u>Given</u>
<u>The value of R(0.8) is:</u>
- R(0.8) =
- 6*e^(0.8*12.75) =
- 6*e^(10.2) =
C) <u>Given</u>
<u>The value of R(0.3) is:</u>
- R(0.3) =
- 6*e^(0.3*12.75) =
- 6*e^(3.825) =
Equations are statements that have equal values, when compared
The true statement about are x = 1 and x = -11
<h3>How to determine the true statement</h3>
The equation is given as:
Rewrite as:
Expand
Factorize
Factor out x + 11
Solve for x
x = 1 or x = -11
Hence, the true statement about are x = 1 and x = -11

Answer: a= b/ b+2
Step 1: factor out variable a.
a(b+2)= b
Step 2: divide both sides by b+2.
a(b+2)/ b+2 = b/b+2
Answer:
30%
Step-by-step explanation:
To find a percentage of a number, take the part of the number and divide it by the whole, then multiply by 100%.
In this case:
6 / 20 = 0.3
0.3 * 100% = 30%
