Answer:
first blank: 1
second blank: 5/2
third blank: 5/2
fourth blank: 4
Step-by-step explanation:
this is just what I put so sorry if it’s wrong but here’s how I got them:
second blank: # yards / # shorts
third blank: 5/2 times 1 = 5/2
fourth blank: 5/8 s times 8/5 equals s and 5/2 times 8/5 equals 4 therefore s=4
The x-coordinate of the vertex can be found by -b/2a where the equation is ax^2 + bx + c
3x^2 + 6x + 3
b is 6, and a is 3
-b/2a = -6/2(3) = -6/6 = -1
The x-coordinate of the vertex is -1. To find the y-coordinate plug the x-coordinate into the equation and solve for y.
f(-1) = 3(-1)^2 + 6(-1) + 3
= 3(1) - 6 + 3
= 3 - 6 + 3
= 0
The y-coordinate is 0
The vertex is (-1, 0)
If this a table then the right side would be x and the left would be y. To find the y intercept you would have to find the zeroth term. (85 is the first term) i think the zeroth term might be 65. i subtracted 20 from 85 since that seems to be the pattern for y.
Answer:
cannot be simplified anymore
Step-by-step explanation:
b(a+c)
Answer:
a equals 105°
Step-by-step explanation:
angles in a straight line add up to 180°
a+75=180
a=180-75
a=105°
