Answer: D
25/6 hours
Step-by-step explanation:
I believe it is $64.28
First you divide 45/7 to find out what 10% of 45 is since 70% is $45
45/7= 6.42, so now you multiply 6.42 by 3 to fin out what the 30% is
6.42(3)= $19.28
Now you add $19.28+45 to add the 30% and the 70%, which is $64.28
Hi, The answer is 2x^2-8x+12, because when you subtract the polynomial with the answer you will get x^2-4
Answer:
c. 108.4
Step-by-step explanation:
cos theta = (u dot v)/ (||u|| ||v||)
where dot stands for dot product and || || is the magnitude
u = (1,5) v= (7,-4)
u dot v = (1*7 + 5*-4) = 7-20 = -13
||u|| = sqrt( 1^2 +5^2) = sqrt(1+25) = sqrt(26)
||v|| = sqrt(7^2 + (-4)^2) = sqrt(49+16) = sqrt(65)
cos theta = -13/ sqrt(26) sqrt(65)
cos theta = -13 /sqrt(1690)
theta = arccos (-13/sqrt(1690))
theta = 108.43
That's an equation that describes a linear and proportional relationship between 'x' and 'y'. The graph of that equation is a straight line through the origin whose slope is. 1/3 .
