7 and -4
Coefficients are the numbers before a variable, meaning that 7 and -4 (be careful of that subtraction sign) are the coefficients. Additionally if you were asked what the leading coefficient was the answer would be 7 because it has the greatest exponent attached to it (2).
Answer:
in the step-by-step
Step-by-step explanation:
okay one thing is that you labelled wrong since you have to label D', D", D'" (you just labelled with one for all of them)
a you reflected across the y-axis wrong
-it would be that D' (-2,6), E' (-2,3), F' (-5,3)
b you rotated correctly
this gets more confusing since you labelled the triangles wrong, but I hope this first part helps
Answer:81
Step-by-step explanation:
Because the square root of 81 is 9 which is a perfect square
720 divided by 72 is 80
7 tens divided by 9 is 8
The way you'd set it up would be sin55º/12=sinB/14 (you could also flip the equation so that 12/sin55º=14/sinB, you'll get the same answer either way). Multiply out so that its 14•sin55º=12•sinB, or 11.47=12•sinB. Divide both sides by 12 so that it looks like .96=sinB, then take arcsine of both sides (arcsin= x=sin^-1 theta+360n or x=180- (sin^-1 theta)+360n), which should give you about 72.88º and 107.12º.
