For this case we have that by definition, the Greatest Common Factor (GCF) is the largest factor that 2 numbers have in common.
So, we have the following expressions:
We look for the positive integers that divide to 35 and 42 without leaving residue:
42: 1,2,3,6,7,14,21
35: 1,5,7
Thus, the GCF of 42 and 35 is 7
Then, the GCF of the three expressions is:
Answer:
Answer:
<h3>The option C) 15 s is correct</h3><h3>Therefore the maximum height it reaches in <u>15 seconds. </u></h3>Step-by-step explanation:
Given equation is
Given that a projectile is thrown upward so that its distance above the ground after t seconds is
"The standard form of a parabola's equation is expressed as :
.
If , then the parabola opens upwards;
if the parabola opens downwards."
The maximum height is the vertex of the parabola which is
.
Comparing the given equation with the standard form of parabola we get
the values of a=-13 , b=390 and c=0
The maximum height in .
Substitute the values we get
Answer:
$142.95
Step-by-step explanation:
Given Original value of the sofa = $349
Rate of depreciation each year = 20%
Number of years = 4
To find the value of the sofa after 4 years use depreciation formula:
If the constant decrease in population be R% per annum. Then the population after n years is
= 142.9504
= 142.95 (Nearest cent)
Hence, the value of sofa after 4 years is $142.95.
