Hello! :)
Answer:
<u><em>ANSWER SHOULD BE BOLD IT IN!</em></u>
Step-by-step explanation:
Distributive property: a(b+c)=ab+ac
2*3-2*8y
2*3=6
8*2=16
<u><em>6-16y is the final answer.</em></u>
Hope this helps you!

Answer:
(x-1)²+(y-3)²=65
Step-by-step explanation:
the common view of the equation of a circle is:
a) (x-a)²+(y-b)²=r², where (a;b) - the centre of the required circle, r - the radius of the required circle;
b) using the coordinates of the endpoint of the given diameter it is possible to calculate the coordinates of the centre of the required circle and its radius²:
the coordinate x of the required circle is: (9-7)/2=1;
the coordinate y of the required circle is: (2+4)/2=3.
the radius² of the required circle is:
r²=0.25*[(9- -7)²+(2-4)²]=0.25*260=65.
c) after the substitution the values of 'a'; 'b' and 'r²' into the common equation of the circle:
(x-1)²+(y-3)²=65.
PS. additional: the given points (9;2) and (-7;4) belong to the final equation, if to substitute their coordinates into it.
The suggested way of solution is not the only one.
25+14=39
R=25
Hope I helped
Answer:
δx=0.035 m
Step-by-step explanation:
We use the expression of the uncertainty of x:
δx = (x/(vo cosθ))*sqrt((cosθ)² (δV₀)²+(V₀ sinθ)²(δθ)² )
First of all, we need to identify δV₀ and δθ. In our case δV₀ = 0.002 m/s and δθ = 0.0175 rad.
Remember: 1° = 0.0175 rad. This is very important to get the right answer here.
Now, we just need to replace the values we have into the equation δx:
δx = (0.5/(3.49*cos(76)))*sqrt((cos(76))²*(0.02)²+(3.49*sin(76))²*(0.0175)²)
δx = 0.035 m.
Have a nice day!
