A) √50 = 2√25 . Her mistake was that she confused the radicand (25) & the outside factor to the radicand that is 2. The write answer is 5√2 & not the opposite
b) Find 2 numbers where their square nears the lower & the upper end of 50.
For instance 7² = 49 & 8² =64 are the nearest lower & upper numbers that encompass 50
Hence we can write the following inequality:
49<50<64 & √49<√50√64 ==> 7<√50<8
So the √50 is nearer to 7² rather than 8².
Then let's try 7.1² =50.41 Which is an acceptable approximation
Answer:
5.14 ft
Step-by-step explanation:
The perimeter of a circle is diameter X 3.14. since its half a circle, take the radius and multiply by 3.14. Since the radius is 1, the answer is pi itself. Then add 2 feet for the flat side of the semi-circle
Step-by-step explanation:
p(x) = 2x^2+8x-12
d(x) = x + 1
r(x) = -13
q(x) = 2x + 6
q(x)+r(x)d(x)
= 2x + 6 + (-13) * x + 1
= 2x + 6 -13 * x + 1
= 2x + 6 - 13x + 1
= (- 11x + 7)
y - y1 = m(x - x1) is the general point slope form
y - 3 = 5(x - 4) plug in the given values
y - 3 = 5x - 20
y = 5x - 20 + 3
y = 5x - 17
The answer in slope intercept form is y = 5x-17
If you want to convert to standard form, then
y = 5x - 17
y+17 = 5x
17 = 5x - y
5x - y = 17 which is the answer in standard form (Ax + By = C)
