The diameter of a circle measures 7 5/6 inches. What is the radius of the circle? Enter your answer as a mixed number in the box
andrew-mc [135]

The radius of the circle expressed as a mixed number is:  3\frac{11}{12} inches.

<h3>What is the Radius of a Circle?</h3>

Radius of a circle = half the measure of the diameter of a circle.

Given:

diameter of a circle = 7\frac{5}{6} inches

Therefore:

Radius of the circle = 1/2(7\frac{5}{6})

= 1/2(47/6)

= (1 × 47)/(2 × 6)

= 47/12

= 3\frac{11}{12} inches.

Therefore, the radius of the circle expressed as a mixed number is:  3\frac{11}{12} inches.

The archway to the entrance of an art gallery can be model by y= -1/3(x-5)(x+5) where x and y are measured in feet. The x-axis r
NikAS [45]

Answer:

x=5 feet

Step-by-step explanation:

At floor level y=0

If the expression is:

0=1/3(x-5)(x+5)\\0=1/3(x^2-25)\\0=1/3x^2-25/3\\25/3=1/3x^2\\25=x^2\\x=5

But, with the negative sign, the answer is x= 5i (where i is imaginary)

Answer:

Step-by-step explanation:

I really hope that solving a few trig questions can forestall death. That would be a really easy way to get rid of the C 19 restrictions and a myriad other diseases. BETTER LIFE THROUGH MATH will be our motto.

11) tan45 = x/13     x = 13

   cos45 = 13/y     y = 13√2

12) sin30 = 4/x      x = 8

     tan30 = 4/y     y = 4√3

13) sin60 = 21/x    x = 21(2/√3) = 42/√3

    y = xcos60 = (42/√3)(1/2) = 21/√3

14) cos45 = x/22   x = 22/√2

     sin45 = y/22   y = 22/√2

15) Height = 24sin30 = 12

cos 45 = 12/x   x = 12/√2

tan45 = y/12      y = 12

cos30 = z/24    z = 24(√(3)/2) = 12/√3
