The circumference of one coin is 8.03cm. The circumference of another coin is 0.33cm smaller. A.) what is the first step to find
Burka [1]

Answer:

Diameter of the smaller coin = 2.46 cm

Step-by-step explanation:

Circumference of a coin = 2πr

Circumference of coin A = 8.03 cm

Circumference of coin B = 8.03 cm - 0.33 cm

A.) what is the first step to find the diameter of the smaller coin?

Find the circumference of coin B

Circumference of coin B = 8.03 cm - 0.33 cm

= 7.7 cm

B.) Find the diameter of the smaller coin.

Circumference of a coin = 2πr

7.7 = 2 × 3.14 * r

7.7 = 6.28r

r = 7.7 / 6.28

r = 1.23 cm

Diameter = 2r

= 2 * 1.23 cm

= 2.46 cm

Diameter of the smaller coin = 2.46 cm

12 NEED HELP ASAP WILL GIVE BRAINLY
Evgen [1.6K]

Answer:

x = 4

8(4) - 2 = 30

15(4) = 60

All triangles equal 180 degrees and there is already a right angle. 60 plus 0 is 90, and 90 plus 90 (or 90 times 2) is 180

60 + 30 = 90

90 + 90 = 180

I can't get to get this right can you please help me​

Answer:

(-7,4]\text{ or }\{x|-7

Step-by-step explanation:

The domain is the span of x-values covered by the function.

From the graph, we can see that the graph covers all the x-values from x=-7 to x=4.

However, note that closed and open circles. There is an open circle at x=-7, which means that the domain excludes x=-7. However, the circle at x=4 is closed, meaning it is included in the domain.

Therefore, the domain is, in interval notation:

(-7,4]

We use parentheses on the left because we do not include -7. And we use brackets on the right because we <em>do </em>include the 4.

And in set notation, this is:

\{x|-7

The roots of the equation are 3 + 8i and 3 – 8i.
g100num [7]
Given that the roots of the equation x^2-6x+c=0 are 3+8i and 3-8i, the value of c can be obtained as follows;
taking x=3+8i and substituting it in our equation we get:
(3+8i)^2-6(3+8i)+c=0
-55+48i-18-48i+c=0
collecting the like terms we get:
-55-18+48i-48i+c=0
-73+c=0
c=73
the answer is c=73
