Answer:
272
Step-by-step explanation:
note that (f • g)(x) = f(x) × g(x) = (3x - 7)(4x - 5)
To evaluate substitute x = 3 into (3x - 7)(4x - 5)
(f • g)(- 3) = (- 9 - 7)(- 12 - 5) = - 16 × - 17 = 172
The scale factor is 3. all of them are 3.
Answer:
18
Step-by-step explanation:
=2(cot²A+1)
=2cosec²A. [` . ` cot²A+1=cosec²A] =2(1/sinA)²
[' . 'cosecA=1/sinA]
=2×3²/1
=2cot²a+2=2×8+2=16+2=18
‘a’ is a variable
so this means something multiplied by 1/2 = 11
to solve we will divide both sides by 1/2 to isolate ‘a’
so a= 22
you can verify by plugging 22 into a
so
(1/2)(22)=11
which is true
