Answer:
d= 12.2 C= 38.3
Step-by-step explanation:
The radius of a circle is half of the diameter so multiply 6.1 by 2
6.1 x 2 = 12.2 ft
To find the circumference:
C = 2πr
C = 2(3.14)(6.1)
C= 2(19.154)
C= 38.3
Given a quadratic function
y = 4x² - 19x - 5
or i will write it as
4x² - 19x - 5 = y
Zero of the function is when y have the value of zero.
So the quadratic equation will be
4x² - 19x - 5 = y
4x² - 19x - 5 = 0
Now make the equation to intercept form by factorization
4x² - 19x - 5 = 0
(4x + 1)(x - 5) = 0 (this is intercept form)
Solution 1
4x + 1 = 0
4x = -1
x = -1/4
Solution 2
x - 5 = 0
x = 5
SUMMARY
-1/4 and 5 are zero function of f(x) = 4x² - 19x - 5
5, 10, 30, 60, 180, 360, 1,080
5*2=10
10*3=30
30*2=60
60*3=180
180*2=360
360*3=1,080
Answer: x= 2/15
as a decimal it is x=0.13 and a line on top of the 3
but your answer is
