ok is a theme for all of us who 6th assignment and we are going too far from changes to our schedule so we will not have a party
<span>What are the factors of y=4x^2 + 2x - 30?
First, divide 2 out of this expression. y = 2(2x^2 + x - 30)
One way to factor this would be to find the roots using the quadratic formula:
Since a=2, b=1 and c= -15,
-1 plus or minus sqrt(1^2-4(2)(-15)
x = -------------------------------------------------
4
-1 plus or minus sqrt(121) -1 plus or minus 11
= -------------------------------------- = ----------------------------
4 4
One such solution is -12/4, or -3. The corresponding factor is (x+3), and the other is 5/2, leading to the factor (2x-5).
Therefore, </span><span>4x^2 + 2x - 30 = y = 2(2x-5)(x+3).</span>
Answer:
Option (3)
Step-by-step explanation:
Given function is,
f(x) = x⁴ + x³ - 2x²
= x²(x² + x - 2)
= x²(x² + 2x - x - 2)
= x²[x(x + 2) - 1(x + 2)]
= x²(x + 2)(x - 1)
So the factored form of the polynomial function is,
f(x) = x²(x + 2)(x - 1)
For x - intercepts,
F(x) = x²(x + 2)(x - 1) = 0
x = -2, 1
This function has even multiplicity = 2 at x = 0.
Therefore, graph of the function will touch the x-axis at x = 0
And at other roots x = -2, 1 has odd multiplicity = 1, so the graph will cross the x-axis.
Option (3) will be the correct option.
Answer:
The critical value for this case can be calculated using the t distribution with 7 degrees of freedom and the critical value would be a value who accumulates 0.1 of the area in the right of the distribution and the best decision based on the possible options would be:
c). Reject H0 if test statistic is greater than 1.895.
Step-by-step explanation:
The system of hypothesis for this case are:
Null hypothesis: 
Alternative hypothesis: 
The statistic for this case is given by:
The degrees of freedom are given by:
The p value for this case can be calculated from this probability:
The critical value for this case can be calculated using the t distribution with 7 degrees of freedom and the critical value would be a value who accumulates 0.1 of the area in the right of the distribution and the best decision based on the possible options would be:
c). Reject H0 if test statistic is greater than 1.895.
