19^2 + x^2 = 21^2
19^2 = 361
21^2= 441
361 + x^2 = 441
x^2 = 441-361 = 80
x = sqrt(80) = 8.944 round to nearest tenth = 8.9
Let's say S is the age of the youngest sister. Then the age of the middle sister is S + 1, and the age of the oldest sister compared to the youngest is S + 2 we have54 = S + (S+1) + (S+2)which is the same as54 = 3S + 3 divide both sides by 354 / 3 = S + 118 = S + 1 subtract one from both sides17 = S check54 = 17 + 18 + 19 ( Hope this helps!!!!)
True, parallelogram needs to be parallel on each side
Answer:
(1,0)
Step-by-step explanation:
The point that f(x) = log₂x and g(x) = log₁₀x have in common is where both graph intersect.
Recall that the logarithm of 1 is 0.
This implies that, when we plug in x=1 into both function we get 0.
g(1) = log₁₀1=0
f(1) = log₂1=0
This means the two graphs intersect at (1,0)
Therefore the graphs of f and g have (1,0) in common
