Answer:
Below in bold.
Step-by-step explanation:
The identity is of the form
(a + b)^2 = a^2 + 2ab + b^2.
a) Sqrt 49 = 7 and we need + 28 as the middle coefficient . We get this with
2*7 + 2*7 so the first coefficient is 2*2 = 4.
So * = 4a^2.
(2a + 7)^2 = (2a + 7)(2a + 7) = 4x^2 + 14a + 14a + 49.
b) -6 * -6 = 36 -24 = 2*-6 + 2 *-6 so the last term is 4x^2
c) The middle term must be an 'ab' term.
sqrt 6.25 = 2.5 and sqrt 1/4 = 1/2
So the coefficient of the middle term is 2.5 * 1/2 + 2.5 * 1/2
= 2.5
So the middle term is 2.5ab.
d) The first term will be in b^2.
100 = 10* 10 and we need 2 as a middle term so coefficient of the first term
will be 1/100 or 0.01. as the 2 comes from 0.1 * 10 + 0.01 * 10 and (0.1)^2 = 0.01
So it is 0.01b^2.
Answer:
(0, 3 )
Step-by-step explanation:
To find the y- intercept , substitute x = 0 into f(x), that is
f(0) = 3 × 
[ note = 1 ]
= 3 × 1
= 3
y- intercept = (0, 3 )
Yes, because a rational number is any number that can be expressed as a fraction a/b where a/b are both integers, but cannot be zero.
chord distance center theorem
if two chords are equidistant from the center, namely, they're the same distance away from the center of the circle, then those chords are twins.
so, therefore if RA is 9.3, VI her twin is also.
Answer: No
Step-by-step explanation:
Volume of one piece= πr^2h
=π ×1×1×1
=3.141
Volume of all the pieces=3.141×24
=75.38ft^3
Volume of board - volume of the pieces= 35-75.38
=-40.38
The answer is negative so the board doesn't have enough volume for all the pieces
