Answer:

A ≈ 78.5

Your answer was wrong because it said to round to the nearest tenth.

Step-by-step explanation:

First, to find the area of a circle, you need the radius or diameter of a circle. You can see that the radius is 5 (counting the units from E directly horizontal to the edge of the circle).

Area of a circle is:

A = πr²

A = π (5)²

Following PEMDAS (order of operations), you would do the exponent first:

A = π (25)

A ≈ 78.5

Solve for m 1/C+1/m=1/z

9966 [12]

Answer: " m = zC / (C − z) " .
___________________________________
Explanation:
_________________________
Given: 1/C + 1/m = 1/z ; Solve for "m".

Subtract "1/C" from each side of the equation:
____________________________________
1/C + 1/m − 1/C = 1/z − 1/C ;

to get: 1/m = 1/z − 1/C ;
____________________________________
Now, multiply the ENTIRE EQUATION (both sides); by "(mzC"); to get ride of the fractions:
_________________

mzC {1/m = 1/z − 1/C} ;

to get: zC = mC − mz ;

Factor out an "m" on the "right-hand side" of the equation:

zC = m(C − z) ; Divide EACH side of the equation by "(C − z)" ; to isolate "m" on one side of the equation;

zC / (C − z) = m(C − z) / m ; to get: 24/8 = 3 24

zC/ (C − z) = m ; ↔ m = zC/ (C − z) .

F(x) = -x² – 10x + 16 Find f(-7)

Gala2k [10]

Answer:

-5

Step-by-step explanation:

or, f(x) = -x^2+10x+16

or, f(7) = (-7)^2+10*-7+16 (-7*-7=49)

=49-70+16

=65-70
