Answer:
A
Step-by-step explanation:
To calculate the slope m use the slope formula
m = ( y₂ - y₁ ) / ( x₂ - x₁ )
with (x₁, y₁ ) = (- 3, - 7) and (x₂, y₂ ) = (9, 1) ← 2 points on the line
m =
=
= 
Answer:
0.611 rad
Step-by-step explanation:
For the radian measure:
180° = π radians
180° : 110° = 11 / 18 ≈ 0.611
110° = 11π/18 rad ≈ 0.611 rad
Hey there!
If the tallest trophy is about 270 inches, and you stack 4 of those trophies on top of each other, you'd be multiplying 270 times 4.
270×4= 1,080
So, if you stacked four 270-inch trophies on top of each other, they would be 1,080 inches high.
Answer:
2.28 and 0.22
Step-by-step explanation:
2x²+1=5x
2x²-5x+1=0
this cannot be properly factorized
so let's use the almighty formula,

where a=2, b=-5, c= 1
=-(-5)±√{(-5)²-4x2x1} x 1/(2 x 2)
=5±√25-8 x1/4
=5±√17 x ¼
=(5±4.12)/4
=2.28. or. 0.22
roots=2.28 and 0.22
Answer:
