One way is to estimate
1^2=1
2^2=4
3^2=9
4^2=16
5^2=25
6^2=36
7^2=49
8^2=64
the number 61 is between 49 and 64 therefor the square root of 61is between the intigers 7 and 8 or -7 and -8

Answer:

The height of the ladder is 14.491 feet

Explanation:

Given the height is 11 feet

Base = 7 + 2 = 9 feet

Consider the ladder to be the hypotenuse

Applying Pythagoras Theorem,

$H^2 = P^2 + B^2$

Substituting the values in the above formula,

$H^2$ = 112 + 92

$H^2$ = 121 + 81

$H^2$ = 210

H = sqrt(210)

H = 14.491

Therefore, the height of the ladder is 14.491 feet

Answer:

The value of f(g(3) = 1,008

Step-by-step explanation:

Step:-1

Given f(x) = $3 x ^ 2 + 2 x$

and g(x) = 3x+9

h(x) = 12+x

Given g(x) = 3x+9

put x =3

g(3) = 3(3)+9

g(3) = 18

Step :-(2)

f(g(3)) = f(18)

f(g(3) = 3(18)^2 +2(18) (since f(x) = $3 x ^ 2 + 2 x$ )

= 1,008

Final answer:-

The value of f(g(3) = 1,008
