Answer:
f(-2) = 20
Step-by-step explanation:
f(x) = 2x² - 3x + 6
f(-2) = 2(-2)² - 3(-2) + 6
= 2(4) + 6 + 6
= 8 + 12
= 20
Answer:
12
/ 24
Step-by-step explanation:
ΔXZW is a 30-60-90 triangle whose sides are in the ratio of 1 :
: 2, respectively
also, ΔXZW ≅ ΔYZW
so XW = 12
XZ = 24
WZ = 12
cos ratio of ∡XZW is WZ/XZ which is:
12
/ 24
Answer: <
6.12 x 10^4 < 612,000
Step-by-step explanation:
The isosceles triangle length of each leg would have to be greater than 7
Answer:
3/2
Step-by-step explanation:
We can use the slope formula
m = ( y2-y1)/(x2-x1)
= ( 5-2)/(8-2)
= 3/2
