Answer:

The area of the sector in circle <em>G</em> formed by segments \overline{AG}, and \overline {GB} is approximately 125.66 square units

Step-by-step explanation:

The given parameters are;

The radius of the circle with center <em>G</em>, r = 15

The measure of the given angle, m∠AGB = 64°

The area of a sector is given as follows;

Area of a sector of a circle = (θ/360°) × π × r²

Therefore;

The area of the sector in circle <em>G</em> formed by segments \overline{AG}, and \overline {GB} is given as follows;

The area of the sector in circle <em>G</em>  = (64°/360°) × π × 15² ≈ 125.66 square units

What you must do in this case is to find the roots of the polynomial.
 We have then:
 x ^ 2 + 20x + 100 = 36
 Rewriting:
 x ^ 2 + 20x + 64 = 0
 The values of the roots are:
 x1 = -4
 x2 = -16
 Remember that the values of the roots are what make the polinome zero
 Answer:
 x1 = -4
 x2 = -16

Given that <br> f(n) = n^2 - 4n + 3 <br> &amp; g(n) = 2n - 1<br> find gf(-2)
icang [17]

Answer:

The value of gf\left(-2\right) will be:

  • gf\left(-2\right)=29

Step-by-step explanation:

Given the functions

f(n) = n^2 - 4n + 3

g\left(n\right)\:=\:2n\:-\:1

f\left(-2\right)\:=\:\left(-2\right)^2\:-\:4\left(-2\right)\:+\:3

           =\left(-2\right)^2+4\cdot \:2+3

           =2^2+4\cdot \:2+3

            =2^2+8+3

            =4+11

            =15

so

gf\left(-2\right)=g\left(15\right)

             =2n-1=2\left(15\right)-1=30-1=29

Therefore,

  • gf\left(-2\right)=29
