Answer:
x=-2 x=1
Step-by-step explanation:
16x2 + 10x – 27 = -6x + 5
Add 6x to each side
16x^2+6x + 10x – 27 = -6x+6x + 5
16x^2 +16x -27 = 5
Subtract 5 from each side
16x^2 + 16x – 27-5 = 5 - 5
16x^2 +16x -32 = 0
Factor out 16
16 (x^2 +x-2)=0
Factor
16 (x+2) (x-1) =0
Using the zero product property
(x+2) =0 x-1=0
x=-2 x=1
Step-by-step explanation:
Volume =pir^h
V1=pi r1^h
V2=pir2^2h
Now,V1/V2=r1^2/r2^2
v1/v2=r1^2/(1.05)^2 ((r2=r1+5/100r1)
v1/v2=1/1.1025
v1/v2=0.907
(v1/v2-1)=0.0907×100%
(v1-v2)/v2=9.07%
increase in volume is 9.07%

Answer:
C.-1.6
Step-by-step explanation:
distance: -1 - (-2) = 1
1 ÷ 5 = 1/5
-1 - 1/5 × 3 = -1 3/5 = -1.6
Answer:
3
Step-by-step explanation:
g(x) = f(x) + k, is true for all values of x.
At x = 0, f(x) = 2
At x = 0, g(x) = 5
Therefore, at x = 0
=> g(x) = f(x) + k
=> 5 = 2 + k
=> 3 = k
Since, the given relation is true for all real values of x, k is independent of x. Thus k = 3, for every value of x
