1. If m
2. Given: <1 and <3 are supplementary.
<3 and <4 form a linear pair.
Prove: <1 is congruent to <4

Again, thanks.

I know that I use SSS, SAS, ASA, HL, and AAS to see if two triangles are
congruent. I also know that SSA is not supposed to be used. The basic way
to use it is using HL, with a right triange. I also was told there was
another example of two congruent traingles with SSA that are not right
triangles.

A tennis ball is launched with an initial velocity of 24.5 m/s from the edge of a cliff that is 117.6 meters above the ground. Which quadratic equation could be used to correctly determine when the ball will hit the ground:


4.9t2 + 24.5t + 117.6 = 0
-4.9t2 - 24.5t + 117.6 = 0
-4.9t2 + 24.5t - 117.6 = 0
4.9t2 + 24.5t - 117.6 = 0
-4.9t2 + 24.5t + 117.6 = 0

could you please explain how u got your answer?

There should be 3 solutions, I got 2... x = a - square root of x and x = a^2 - 2ax + x^2.

How do I solve the problem.

2007-10-22 10:26:53 · 15 answers · asked by sohogurl 1

Okay, for anyone that is good at linear programming, I have a question. Well, there's this problem I'm stuck on, and I need help on a few things on it. Here's the problem:
X is the mathematician for Y's Oil Refinery. Y can buy Texas oil, priced at $30 a barrel, and California oil, priced at $15 per barrel. He consults X, the mathematician, to find out what is the most he might have to pay in a month for the oil the refinery uses. Sabrina finds the following restrictions on the amounts of oil that can be purchased in a month. The refinery can handle as much as 40,000 barrels per month.
To stay in business, the refinery must process at least 18,000 barrels a month. California oil has 6 pounds of impurities per barrel, while Texas oil has 2 pounds. The most the refinery can handle is 120,000 pounds of impurities a month. Y spends at least $660,000 per month buying oil.

What would be the constraints for this problem? That's all I need to know. I think I did something wrong.

Thanks

Samething with y= ax^2+bx+c
abc are constants, and x is a variable. Is that the same for y=mx + b. How do you find x for y=mx+b?

derivative of

f(t)=(2t)/(4+t^2)

y= (t^3 + t)/ (t^4-2)

y=( x^(1/2)-1)/ (x^(1/2)+1)

Simplify this expression. Type the variable term before the constant term.

12 + 3(4 + x)

7(2x + 1) - 7

4(3x + 3) - 10
