Answer:
Step-by-step explanation:
<u>If p is the original price, the markdown price is:</u>
- p - 20% =
- p - p(20/100) =
- p - 0.2p =
- 0.8p
<u>Now, another 20% off:</u>
- 0.8p - 20% =
- 0.8p - 0.8p(20/100) =
- 0.8(p - 0.2p) =
- 0.64p
<u>Answer choices:</u>
- A. 0.2(1p-0.2p)
- B. 0.6p
- C. (1p-0.2p)-0.2p
- D. 0.8p(1p-0.2p)
Correct one is D

Find the number of distinguishable permutations of the letters m, i, s, s, i, s, s, i, p, p, i.
Tatiana [17]
Solution:
we have been asked to find the number of distinguishable permutations of the letters m, i, s, s, i, s, s, i, p, p, i.
Here we can see
m appears 1 time.
i appears 4 times.
S appears 4 times.
p appears 2 times.
Total number of letters are 11.
we will divide the permutation of total number of letters by the permutation of the number of each kind of letters.
The number of distinguishable permutations
Hence the number of distinguishable permutations
Answer:
The range stays the same.
The domain stays the same.
Step-by-step explanation:
The function
is an exponential function, where <em>a</em> is the coefficient, <em>b</em> is the base and <em>x</em> is the exponent.
The domain for this kind of functions is: All real numbers.
And the range is: (0,∞); this happen because the exponential functions are always positive when <em>a</em>>0.
Therefore, if the value of <em>a</em> is increased by 2, the domains will stay the same and the range will stay the same: (0,∞). The coefficient does not change the domain or the range if it keeps the same sign.
