Find the value of the lesser root of x 2-8x+7=0
mariarad [96]
Hi there! The answer is x = 1

{x}^{2}  - 8x + 7 = 0

(x - 7)(x - 1)
Rule AB = 0, gives A = 0 or B = 0

x - 7 = 0 \:  \: or \:  \: x - 1 = 0 \\ x = 7 \:  \:  \:  \:   \:  \:  \:  \:  \: or \:  \: x   = 1
Therefore, the smallest of both roots is x = 1.

1) Find the inverse function of f(x)=1/2x+3
dexar [7]
 y = 1/2x + 3
change x and y

x = 1/2y + 3
now find the value of y and that is inverse function 

x - 3 =1/2 y
y = 2x- 6
 
f-(x) = 2x - 6
<u />

for both domain : ( - ∞ , + ∞ )

range f (x) : ( - ∞ , + ∞ )  - { 0 }

What is the surface are of the cylinder pictured below ​
Elina [12.6K]

Surface area of the cylinder is 294π in².

Step-by-step explanation:

  • Step 1: Surface area of a cylinder = 2πrh + 2πr² Here, r = 7 in, h = 14 in

⇒ Surface Area = 2 × π × 7 × 14 + 2 × π × 7 × 7

                          = π (196 + 98) = 294π in²
