Answer:
25.1cm
Step-by-step explanation:
C=2πr
here radius, r=4 cm and π=3.142
Put values in formula.
C=2(3.142)(4)
C=25.1 cm (Rounded to 1 decimal place)
Answer:
Part 1)
Part 2)
Part 3)
Step-by-step explanation:
we know that
EB=ED+DB
ED=DB -----> given problem
Substitute the given values and solve for x
<em>Find the value of ED</em>
substitute the value of x
<em>Find the value of DB</em>
Remember that
ED=DB
therefore
<em>Find the value of EB</em>
EB=ED+DB
The answer is -4,7
The denominator can't equal zero. Factor the denominator:
x^2 - 3x - 28=
(X - 7)(x + 4); next set each set of parentheses equal to 0;
x - 7 = 0; so x=7 is one value
x + 4 = 0; so x=-4 is the other
Remember, x = 7 and x= -4 make the denominator zero, which is a "restriction" because you can't divide by zero.
Answer:
min{5 x^2 - 20 x + 3} = -17 at x = 2
