Answer:
(2v-1)(21v^2+17)
Step-by-step explanation:
add and subtract the second term to the expression and factor by "grouping"
answer should be:
(2v-1)(21v^2+17)
the answer its 12.5% i swer its ok and hope helps you
By estimation, 3.9 turns into 4 and 5.3 turns into 5. The answer after estimation is 20 while the real answer is 20.67. Well u see by estimation we get an answer of two places right. So, real answer should also have two places.Place the decimal point after it.y43
Step-by-step explanation: i dont know if I'm right or not
Here in the second term I am considering 2 as power of x .
So rewriting both the terms here:
First term: 12x²y³z
Second term: -45zy³x²
Let us now find out whether they are like terms or not.
"Like terms" are terms whose variables (and their exponents such as the 2 in x²) are the same.
In the given two terms let us find exponents of each variable and compare them for both terms.
z : first and second term both have exponent 1
x: first and second term both have exponent 2
y: first and second term both have exponent 3
Since we have all the exponents equal for both first and second terms variables, so we can say that the two terms are like terms.
Answer:
f(t) = 62 ⋅ 0.9953t
Step-by-step explanation:
The function decreases at a rate of 0.47%
That will mean, the initial value decreases by 0.47?
100% - 0.47% = 99.53%
The next value will be 99.53% of the initial value.
∴ 99.53% × 62 = 0.9953 × 62.
After a time t, the value will be:
0.9953t × 62
∴ Answer = 62 × 0.9953
