Answer:
answer choice ?
Step-by-step explanation:
Answer:
Step-by-step explanation:
The degree of polynomial is the sum of exponents of the variables involved in the expression,hence the given degree is
2+3=5,so 5 is the degree of the polynomial.
Answer:
1. x = 6/-2b
2. x = -1
Step-by-step explanation:
X in terms of b just means solve for x but you don't have a specific number because one isn't given for b.
-2(bx - 5) = 16
-2bx + 10 = 16
-2bx + 10 - 10 = 16 - 10
-2bx = 6
-2bx/-2b = 6/-2b
x = 6/-2b
To find x when b = 3, just plug in 3 for b.
x = 6/-2(3)
x = 6/-6
x = -1
Answer:
The answers are B and E
Step-by-step explanation:
The square root of 4 is 2.
The cube root of 8 is 2.
A is wrong because its value is 4.
C is wrong because its value is 4.
D is wrong because the square root of 8 isn't whole.
Answer:
A = 0.75 gram or 1 gram
Step-by-step explanation:
The half-life of carbon 14 is years. How much would be left of an original -gram sample after 2,292 years? (To the nearest whole number).
We can use the following formula for half-life of to find out how much is left from the original sample after 2,292 years:
where:
<em>A</em> is the amount left of an original gram sample after <em>t</em> years, and
is the amount present at time <em>t</em> = 0.
The half-life of is the time <em>t</em> at which the amount present is one-half the amount at time <em>t </em>= 0.
If 1 gram of is present in a sample,
Solve for A when t = 2,292:
Substituting = 1 gram into the decay equation, and we have:
A = 0.75 g or 1 g
