The larger angle of two supplementary angles has a measure of 20° more than the measure of the smaller angle. find the number of
Sergio [31]
Let smaller angle be x
Let larger angle be 20 + x
Sum of two supplementary angles = 180°
x + 20+ x = 180°
2x + 20 = 180
2x = 180-20 = 160
x = 160/2 = 80

Smaller angle = x = 80°
Larger angle = 20 + x = 20 + 80 = 100°
I hope it is helpful:D

Write a polynomial function in factored form with double roots at -2 and 5 and the constant term of the polynomial in standard f
Amanda [17]

Answer:

f(x)=-0.4x^4+2.4x^3+8.4x^2-24x-40

Step-by-step explanation:

If -2 and 5 are double roots of the polynomial function, then the function expression is

f(x)=a(x-(-2))^2(x-5)^2\\ \\f(x)=a(x+2)^2(x-5)^2

Rewrite this function in standard form:

f(x)=a(x^2+4x+4)(x^2-10x+25)\\ \\f(x)=a(x^4-10x^3+15x^2+4x^3-40x^2+100x+4x^2-40x+100)\\ \\f(x)=a(x^4-6x^3-21x^2+60x+100)\\ \\f(x)=ax^4-6ax^3-21ax^2+60ax+100a

The constant term of the polynomial in standard form is -40, so

100a=-40\\ \\a=-\dfrac{40}{100}=-0.4

Therefore, the function expression is

f(x)=-0.4x^4-6\cdot (-0.4)x^3-21\cdot (-0.4)x^2+60\cdot (-0.4)x+100\cdot (-0.4)\\ \\f(x)=-0.4x^4+2.4x^3+8.4x^2-24x-40
