All angles in a triangle add to 180
so
w+2w+69=180
3w+69=180
3w=111
w=37
Answer:
False
Explanation:
No, a triangle cannot be constructed with sides of 2 in., 3 in., and 6 in.
For three line segments to be able to form any triangle you must be able to take any two sides, add their length and this sum be greater than the remaining side.
Answer:
- P = -390t +48,000
- P = 43,710 in 2003
Step-by-step explanation:
A) We are given two pairs of (t, P): (0, 48000), (8, 44880). We can use these with the 2-point form of the equation of a line:
y = (y2 -y1)/(x2 -x1)(x -x1) +y1
P = (44880 -48000)/(8 -0)(t -0) +48000
P = -3120/8t +48000
P = -390t +48000
__
B) In 2003, t = 11, so we have ...
P = -390(11) +48000 = 43710
The population in 2003 is predicted to be 43,710.
Answer:
Step-by-step explanation:
[...] if you can write the LHS as a perfect square, or if you can't spot a factorization of it right away, if and only if the discriminant 
(or, if b is an even number, 1/4 of it) is zero.
<u>I see it! I see it!</u>
Stare at it for a while. First term is 
, third term is 
, we are missing a double product, but we can play with k. For the LHS to be 
you just need 
.
<u>I don't see it...</u>
Then number crunching it is. Set the discriminant to 0, solve for k
