Answer:
B
Step-by-step explanation:
if you connect and extend to points it forms a line with a y-intercept of 2 when x is zero
y = mx + b m the slope equals 1
y = x +2
<span>The dot product here is 10(9) + 6(5)=120
so the vectors are not orthogonal
</span><span>u.v = |u| x |v| cos (theta) ; theta is the angle between them
we know from above that u.v = 120
|u| = sqrt[10^2+6^2]=11.66
|v| = sqrt[9^2+5^2]=10.29
so we know:
theta =cos^-1 120/(11.66x10.29)
so theta = 25 degrees</span><span>

Answer:
9x^5 -1
Step-by-step explanation:
2x^3+7x^2-2 / -2
9x^5-2/2
9x^5 -1
The answer is 240 because 11 x 8 is 88 but you divide by 2 since it's a triangle so you get 44 and since there's 4 triangles you do 44 x 4 and get 176 then 8 x 8 is 64 plus 176 is 240
21.5 x 10 = 215
Move the decimal point over to the right the number of zeros there are in the second number
