Answer:

165

Step-by-step explanation:

First we need to find the area of the field, A = r^2 * pi

The radius is 290 / 2 = 145 feet

A = 145 * 145 * 3.14 = 66018.5 sqr feet

One bag covers 400 sqr feet

Divide the Area by 400 sqr feet to find number of bags needed.

66018.5 / 400 = 165

He will need at least 165 bags to cover the field

4⋅f(6)−6⋅g(5) need help asap

Leto [7]

Answer:

Step-by-step explanation:

From the blue graph of f(x) we can see that the function value is -6 when x = 6. Similarly, g(5) = -5.

Then: 4*f(6) - 6*g(5) becomes:

4*(-6) - 6*(-5), or

-24 + 30 = 6

Help me with geometry plzzzzzzzzzzzzzzzzzzzz

Natalija [7]

Answer:

x = 17

Step-by-step explanation:

A triangle's sum is 180 degrees, hence

6x + 10 + x + 17 + 4x - 34 = 180.

11x + 10 + 17 - 34 = 180

11x - 7 = 180

11x = 187

x = 17

hope this helps and is right!! p.s. i really need brainliest :)

Given that f(x)= x2+3 and g(x)= x+4/3 solve for (f(g(x)) when x =2

Savatey [412]

$\bf \begin{cases}
f(x)=x^2+3\\\\
g(x)=x+\cfrac{4}{3}
\end{cases}
\\\\\\
\boxed{x=2}\qquad g(2)=(2)+\cfrac{4}{3}\implies \boxed{g(2)=\cfrac{10}{3}}
\\\\\\
f(~~g(x)~~)=[g(x)]^2+3\implies f(~~g(2)~~)=[g(2)]^2+3
\\\\\\
f(~~g(2)~~)=\left[ \boxed{\frac{10}{3}} \right]^2+3\implies f(~~g(2)~~)=\cfrac{10^2}{3^2}+3
\\\\\\
f(~~g(2)~~)=\cfrac{100}{9}+3\implies f(~~g(2)~~)=\cfrac{100+27}{9}
\\\\\\
f(~~g(2)~~)=\cfrac{127}{9}$
