Answer:
Y = 10.1 + 1.50x
Step-by-step explanation:
From the data contained in the computer output for linear regression
The coefficient of intercept = 10.1
coefficient of fertilizer = 1.50
Sample of an Equation of least squares regression line
y = a + bx
where : a = intercept , b = slope
hence the required equation will be
Y = 10.1 + 1.50x
y = yield , x = fertilizer
1. The circumference of a circle is 2πr, and when we plug in 3 for r, we get 6π.
2. We'll use the same formula and plug in 10 for r, giving us 20π.
3. The formula we use in this case is πd, and when we plug in 13 for d, we get 13π.
4. Same formula from 3, we plug in 9.5 for d and get 9.5π.
5. You can calculate the circumference of a circle using 2 formulas, C=2πr (where r=radius and C=circumference) and C=πd (where d=diameter and C is circumference).
6. You use 2πr when the radius is given.
7. You use πd when the diameter is given.
8. 2 examples could be to use the 2 formulas.
By graphing the given function. See the attached figure.
We can conclude the following
1. both of them is a rational function.
2. both are not defined for x = 0
3. both have the same symmetry axis: y = x
4. both have the same asymptotes: the y-axis, i.e. y = 0
5. they never touch one to each other
<span>6. y→0</span> as <span>x→±∞</span> for both equations
<span>7. y→+∞</span> as <span>x→<span>0−</span></span> and <span>y→−∞</span> as <span>x→+0</span> for both equations
8. both of them can be obtinad from the parent function using the scales -0.2 and -0.3
9. the function <span><span>y=<span><span>−0.2/</span>x</span></span> is closer to the origin than <span>the function y=<span><span><span>−0.3/</span>x</span></span></span>

Answer:
Below in bold.
Step-by-step explanation:
a³+1+2a²+2a = (a + 1)(a^2 + a + 1)
a^3 - 1 = (a - 1)(a^2 + a + 1)
a^4 + a^2 + 1) = (a^2 - a + 1)(a^2 + a + 1)
So the LCM is (a + 1)(a - 1) (a^2 - a + 1)(a^2 + a + 1).
Answer:
the answer should be 10 to the power of 5
