Answer:
tax =1
Step-by-step explanation:
20=5(3+x)
4=3+x
x=1
x as in tax
Volume of a cylinder is formulated as: π·r²h
Surface area of a cylinder is formulated as: 2π·rh + 2π·r²
So, for a:
Volume = π·5²·12 = π·25·12 = 300π
Surface area = 2π·5·12 + 2π·5² = 120π + 50π = 170π
And it's essentially the same process for the other questions.
Answer:
three
Step-by-step explanation:
1.5 = 1 1/2 = 3/2
When there is a negative exponent, you find the reciprocal of the base, so therefore: 3/2 ^ -2 = 2/3 ^ 2
Then you square the numerator, then square the denominator: 2^2/3^2 = 4/9
Since the centre of dilatation is the origin, we only require to multiply each of the coordinate points by the scale factor 3
(- 2, 1 ) → ( - 6, 3 )
(- 2, 3 ) → (- 6, 9 )
(1, 2 ) → (3, 6 )
(1, 3 ) → (3, 9 )
