find the diameters of a circle with a circumference of 443 feet use 3.14 for n a. 70.5 b. 141 c.142 d.282
zvonat [6]
The formula for diameter is:

circumference/pi (3.14)

If the circumference is 443, we can divide that by pi.

443/3.14=141.01

The answer would then be choice b (141).

Help please asap?!?!?!
Gwar [14]
In similar figures, the angle measures are the same but the side lengths are different.  So in #4, x = 42.  Since all the angles of a quadrilateral added up equal 360, then y is 360-90-90-42=138.  For number 5, make sure you match up the sides correctly in your ratio: \frac{2}{x}= \frac{4}{8}.  You could cross multiply to get 4x=16, and x = 4, or you could just realize that reducing 4/8 will give you 2/4 and x = 4.  Going back to the idea that in similar shapes corresponding angles are the same measure, x in #6 is 63

If function g has the factors (x - 7) and (x + 6), what are the zeros of function g?
SVEN [57.7K]

Answer:

7 and -6

Step-by-step explanation:

Given

Factors: (x - 7) and (x + 6)

Required

Determine the zeros

To do this, we simply equate the factors to 0

x - 7 = 0

x = 7

x + 6 = 0

x = -6

<em>So, the zeros are -7 and 6</em>
