the complete question is<span>Point A has an x coordinate of −2 and lies in a circle with a center at (0, 0) and a radius of 5.
To the nearest tenth, what is the y-coordinate for point A?
A: 4.5
B: 4.6
C: 4.7
D: 4.8
see the attached figure
we know that
the equation of the circle is
(x-h)</span>²+(y-k)²=r²
(h,k) is the center---------> (h,k) is the point (0,0)
r=5 units
so
(x-h)²+(y-k)²=r²--------> (x-0)²+(y-0)²=5²------> x²+y²=25
substitute the value of x=-2 in the equation
(-2)²+y²=25------> y²=25-4------> y=(+/-)√21
the y coordinate of point A is positive----> see the picture
therefore
y=√21-----> 4.58-----> y=4.6
the answer isthe y-coordinate for point A is 4.6

Answer:
n + 11 and 11 + n
Step-by-step explanation:
Let n be the unknown number,
n is increased by 11,
That is, n + 11
By the commutative property of addition,
The expression would be,
11 + n
For drawing a model that shows n + 11
Take two boxes in which first shows n and second shows 11 and add them,
Similarly, for showing 11 + n, take first box that shows 11 and second box that shows n then add them.
<u><em>Answer:</em></u>
<u><em>$55.93 or rounded up is $56</em></u>
<u><em>Division</em></u>
<u><em>First, we would divide 15.98 by 2 to see how many dollars would a bag cost.</em></u>
<u><em>15.98 divided by 2 = $7.99</em></u>
<u><em>Multiplication</em></u>
<u><em>Then, we would multiply by 7 to see how may dollars would it cost for 7 kg bag</em></u>
<u><em>7.99 times 7 = 55.93</em></u>
<u><em>Round-up</em></u>
<u><em>If we round it up, we get $56.</em></u>
