2. x =(6+√20)/-8=3/-4-1/4√ 5 = -1.309
Answer:
Step-by-step explanation:
y - 3 = 1/4(x - 4)
now use algebra to get the above point-slope formula in the slope-intercept formula
y - 3 = 1/4(x - 4)
y - 3 = 1/4x -1
y = 1/4x +2
now that you have the slope-intercept form graph it
Answer:
x^2 - 100 = (x + 10) * (x - 10)
Step-by-step explanation:
Recall that 100 is the perfect square of 10:
10^2 = 100
then we can use the formula for factorization of a difference of squares:
x^2 - 10^2 = (x + 10) * (x - 10)
I think the answer would be -$5.17 because you would have to find the unexpected value.
I think the answer to this picture is 0.122

Answer:
The CPI increased 3.42% in Month 2.
Step-by-step explanation:
In a spreadsheet, the weighted sum is easily computed using the SUMPRODUCT( ) function. It multiplies the corresponding values of two arrays, then returns the sum of those products. If one of the values is a weight, then the result is a weighted sum.
Your CPI is computed as the weighted sum of the prices of the individual products. The percentage change is computed in the usual way:
pct change = ((new value)/(old value) -1) × 100%
Of course, the spreadsheet can format a fraction as a percentage, so the computation of the change can stop after 1 is subtracted from the ratio.
