1) You are estimating the cost (\$K) of optical sensors based on the power output of the sensor. Using the preliminary calculations from a data set of 8 sensors, determine the equation of the line. (Round your intermediate calculations to 3 decimal places) ΣY = 2575 ΣX=680 ΣXY=241400 ΣX2=62600 Cost = -77.005 + 4.693 (Power) Cost = 3.786 + 6.763 (Power) Cost = 6.763 + 3.786 (Power) Cost = 4.693 + (-77.005) (Power)

### Help understanding the quadratic equation

if the quadratic eqn is ax^2 + bx+c = 0 you can use the formula -a +/- sqrt(b^2-4ac) / (2a) in your case, all can be factored 1. (x-5)(x+1) = 0 2. (z-5)(z+3) = 0 3. (y-3)(y+1) = 0 4. (r+5)(r-1) = 0

Please help me understand the first forward difference and second forward difference. Is there any video or we link that you can suggest to me? This is with respect the study of calculus in maths..   http://www.mathsisfun.com/calculus/integration-rules.html a forward difference is the integral to do that you increase the exopnent by one and you put a factor ofoine divided by  the exponent. y = x is my example: first forward difference is Y = 1/2 x^2 second forward difference is Y" = 1/2*1/3 x^3 or Y" = 1/6 x^3 if you take the differencial twice you get the original example.

### How do you factor the sum of terms as a product of the GCF and a sum?

It took me a while to interpret your question, and I came up with a polynomial that had a GCF, but it doesn't have to be a polynomial: 36x^2+45x+63 simplifies when we note that the GCF of the numbers 36, 45 and 63 is 9. That means 9 is the largest integer to divide into the numbers: 36=9*4, 45=9*5 and 63=9*7. This means we can rewrite the polynomial as the product of a GCF and a sum: 9(4x^2+5x+7). It utilises the distributive property of numbers. Another example: abc+ace-ca^2. In this case the GCF is algebraic: ac, because all the terms contain ac, so we can factorise: ac(b+e-a). This is the product of the GCF ac and the sum b+e-a. Another example: 4x^2+2xy+6x=2x(2x+y+3). This time the GCF is 2x because the GCF of the numbers is 2 and of the algebraic quantities is x, so we just combine the two GCFs to make 2x. Does this help you in time? If you still don't understand send me a private message explaining your difficulties and providing examples.

### help factoring polynomials

Have you learned how to find the rational zeros? That is the easiest way to figure this out. Put it in a bracket like this: -2|   1         4    5    2    |             -2   -4  -2 always 1   2     1    0 now you take those new numbers and put them back in this form: x^2+2x+1 that is very factorable. The answer is (x+1) (x+1)

### Problem of the Week Cutting Challenge Grade 5 Problem 23

Tim had 4 paper fraction pieces, each of thirds, fourths, sixths, and twelfths. He did not have enough pieces to show both 2/4 and 1/3 as equivalent fractions with the same denominator. How could he form enough pieces by making 1 cut with a scissors? My daughter had this problem and for the life of me I cannot figure it out...please help so I can understand this myself so I can explain it to my daughter. The only thing I am pretty sure about is that the same or common denominator is 12 (twelfths) but to cut paper once to show for this by producing the pieces with one cut...??? That's where I don't know what to do to demonstrate this with a single cut...Thanks in advanced for your help! 1/3 = 4/12 1/4 = 3/12 1/6 = 2/12 1/12 adding these 4/12 + 3/12 + 2/12 + 1/12 = 10/12 have to make 2/4 or 6/12 and 1/3 or 4/12 Imagine the four pieces in a circle all connected1/3 next two 1/4 next to 1/6 and 1/12 (there is 2/12 not used or missing. The Cut is between 1/3 and 1/4

17 - 8 = 9 "Make a 10" has nothing to do with the solution. It seems your daughter is being polluted with Common Core. I have seen some of the stupid things that are foisted on unsuspecting students who have absolutely no basic math skills. They are ordered to make up ridiculous, extraneous steps that they can't possibly understand, to solve a simple problem such as the one above. Do your daughter a favor. Get her out of public school, FAST!   Problem statrment: 1st grade math 17-8=? make a 10 to figure out answer I dont understand it? Help? I cannot figure out my daughters 1st grade homework from a new program they have go math.

### how do you do fractions?

Problem: how do you do fractions? i need help with fractions and dont understand how oter things eqal 1/2 or how to multipy them. First, look at the fraction 1/2. The denominator (on the bottom) is twice as large as the numerator (on the top). Any fraction that has that same ratio is equal to 1/2. For example, 33/66 = 1/2. 5/10 = 1/2. 47/94 = 1/2. When multiplying fractions, multiply the numerators to obtain a new numerator, then multiply the denominators to obtain a new denominator. Example: (4/7) * (5/13) = (4 * 5)/(7 * 13) = 20/91 The process is the same if you are multiplying three, four or more fractions. (2/8) * (1/3) * (9/16) = (2 * 1 * 9) / (8 * 3 * 16) = 18/384
