Answer:
<h2>4 terms</h2>
Step-by-step explanation:
Term 1: 5x^3
Term 2: 8x^2y
Term 3: 4xy
Term 4: 4
I assume it is the last one, 3n^2, because the degree is the exponent, which is two and the three is the coefficient, which is next to the variable, plus it is a monomial, so there is only one term, eliminating the first two, the third one is just reversed. Therefore, the answer should be the last one. Hope this helps. :)
Answer:
The total earning of Mr Wallace for the week is $310.37
Step-by-step explanation:
Given as :
The fixed weekly salary of Mr Wallace = $275
And The commission of 3% on his total sell
Last week Mr Wallace total sells amount= $1179
I.e 3% of total sells amount = 3% of $1179 = .03 × $1179 = $35.37
∴The total earning = $275 + $35.37 = $310.37
Hence The total earning of Mr Wallace for the week is $310.37 Answer
Answer:
the equation should be corrected to fit the data of the problem. With the corrected equation a mass of 0.5 grams remains after 150 years
Step-by-step explanation:
for the mass y( in grams)
y=23* (1/2)^(t/45), t ≥ 0.
the initial mass is at t=0 , then
y= 23 grams → should be 16 grams
half-life from the equation = 45 years → should be 30 years
the correct equation should be
y=16*(1/2)^(t/30), t ≥ 0
then after 150 years → t= 150
y=16*(1/2)^(150/30)= 16*(1/2)^5 = 16/32 = 0.5 grams
then a mass of 0.5 grams remains after 150 years
