Answer: 120 times.
Step-by-step explanation: 4/8 = x/240. 4/8 x 240/1 4/1 x 30/1 = 120/1 = 120.
Reduce 8 to 1 and 240 to 30.
Answer: A=100(12)t5.27
Step-by-step explanation:
Assume / and ^ got lost from eqns.
A(t) = initial × (1/2)^(t/halflife)
So initial = 100, halflife = 5.27,
A=100(12)t5.27 means A=100(1/2)^(t/5.27)
so that A is 50 when t is 5.27
The answer is 2 √2.
The problem can be simplified by changing the square roots to look like this:
√(8y/y)
Simplify within the square root and you get this:
√8
Factor √8:
√4 √2
Simplify √4:
2 √2
Answer:
x = 4
Step-by-step explanation:
I don't see a picture, so I'm assuming that M, N, O are points on a line segment with endpoints M and O.
Point N bisects segment MO, so it's in the middle of that segment. That means the distance from M to N and the distance from N to O are equal.
7x - 15 = 2x + 5
5x - 15 = 5
5x = 20
x = 4
1) The given expression 7x^4 + 5x^2 + x - 9 is a polynomial.
2) The given expression 7x^6 - 4x^3 + 1/x is a trinomial.
<u>Step-by-step explanation</u>:
1) 7x^4 + 5x^2 + x - 9
- The number of terms in the above expression is 4.
- An algebraic expression with more than 3 terms is known as polynomial.
- <u>The degree is the power of the x term in a expression</u>
- first term = 7x^4 has a degree of 4.
- second term = 5x^2 has a degree of 2.
- third term = x has a degree of 1.
- fourth term = 9 is a constant term with no degree.
2) 7x^6 - 4x - 1/x
- The number of terms in the above expression is 3.
- An algebraic expression with 3 terms is known as trinomial.
- first term = 7x^6 has a degree of 6.
- second term = 4x has a degree of 1.
- third term = 1/x has a degree of -1.
