Write the equation of the circle centered at ( 7 , − 5 ) (7,-5) with diameter 16
galina1969 [7]
The equation of a circle is (x - h)² + (y - k)² = radius² where (h, k) is the center. 

If the diameter is 16, then the radius is 8. 

Your equation is:
(x - 7)² + (y + 5)² = 64

For A I somehow got 41.05 but its 2.95cm can someone show me the working and what I did wrong?
777dan777 [17]

Answer:

Step-by-step explanation:

a). tan(75°) = \frac{\text{Opposite side}}{\text{Adjacent side}}

                  = \frac{11}{k}

    k = \frac{11}{\text{tan}(75)}

    k = 2.947

    k = 2.95 cm

b). cos(52°) = \frac{16}{s}

    s = \frac{16}{\text{cos}(52)}

    s = 25.988

    s ≈ 25.99 cm

c). sin(5°) = \frac{\text{Opposite side}}{\text{Hypotenuse}}

               = \frac{16.1}{q}

    q = \frac{16.1}{\text{sin}(5)}

    q = 184.727

    q ≈ 184.73 cm

9=ln(x+7) | Solve for x
frez [133]
Remember that ln=log_{e}
and

log_{a}x=y means a^y=x
convert
ln(x+7)=9 means
e^(9)=x+7
minus 7 from both sides
e^9-7=x
use calculator to evaluate
