Answer is C. Definitely not d right off the bat because both exponents are negative so cross that out. After that its just counting zeros.
First multiply C by F by multiplying each row in C by each column in F:
12 * -2 + 0*0 + 1.5*2 12*0 + 0*8 + 1.5*1
1*-2 -6*0 +7.2 1*0-6*8 +7*1
to get a matrix of:
-21 1.5
12 -41
Now subtract that matrix from B:
2- -21 = 2+21 = 23
8 - 1.5 = 6.5
0.6 - 12 = -11.4
3 - -41 = 3+41 = 44
So you have:
23 6.5
-11.4 44
Which makes C the correct answer.
Answer:
B
Step-by-step explanation:
The secant- tangent angle b is half the difference of the measures of the intercepted arcs , then
b = 
( 180 - 35) = × 145° = 72.5° → B
Answer: 255°
Step-by-step explanation:
To convert an angle in radians to degree, we've to multiply it by 180/π. In this case, converting the angle 17pi/12 radians to degrees will be:
= 17π/12 × 180/π
= 17 × 15°
= 255°
The answer is 255°.
