Answer:
See below.
Step-by-step explanation:
The area of the circle is given by the formula:
From the circle, we can see that the diameter is 14. Thus, the radius must be 14 divided by 2 or 7.
We're also using 3.14 for π. Substitute:
Use a calculator:
And we're done!

<u>Step</u> <u>Property</u>
2x+6 = 22 given
2x = 16 addition property of equality (-6 added to both sides)
x = 8 multiplication property of equality (both sides × 1/2)
_____
In general equations are solved by reversing the steps done to the variable. Here, the variable (x) is multiplied by 2 and 6 is added to that product. So, to find x, we undo the addition of 6 (by adding -6, the additive inverse), and undo the multiplication by 2 (by multiplying by 1/2, the multiplicative inverse).
If other functions were performed on the variable in the original equation, their inverse functions would be used, too, as part of the solution process.
The equation of a parabola is given by
where
is the vertex.
We have the vertex is (-3,-2) so we have
and
Substituting -3 and -2 into the
Hence, the correct answer is
option D
The answer for the question in the picture is in option B.
The square root of 64 is 8 (because 8*8=64), and the square root of x^16 is x^8 (because x^8 times x^8 is x^16). Put these together to get the answer: 8x^8
Answer:
Perimeter =28 units.
Area = 45 unit^2.
Step-by-step explanation:
The length of first side (joining first 2 points) = 5 - (-4) = 9 (as y coordinates are both -5)
The line joining the 2nd and third points = 0 - (-5) = 5
The line joining the 3rd and 4th points = 5 - (-4) = 9.
The line joining the first and 4th points = 0 - (-5) = 5
So the perimeter = 2(5) + 2(9)
= 28 units.
Area = 5*9 = 45 unit^2.
