Larry is 8 years older than his sister. In 3 years, he will be twice as old as she is now. How old are they now?
erma4kov [3.2K]

Let Sister's age now = s  

So Larry is now s + 8  

In THREE Years Sister = s + 3  

Larry = {s + 8} + 3  

But We are told that he will be TWICE as old as Sister is NOW!!!  

So s + 11 = {2s}  

Solve s = 11  

So Sister is ELEVEN Years old and Larry is NINETEEN Years old.

Which of the following describes the roots of the polynomial function f (x) = (x + 2) squared (x minus 4) (x + 1) cubed?
anastassius [24]

Answer:

A

Step-by-step explanation:

f(x) = (x + 2)^2(x-4)(x + 1)^3

x+2=0

x+2-2=0-2

x=-2.....(x+2) was squared...exponent of 2...multiplicity of 2

x-4=0

x-4+4=0+4

x=4....(x-4) has no visible exponent which means it is essentially to the power of 1...multiplicity of 1

x+1=0

x+1-1=0-1

x=-1....(x+1) was cubed...exponent was 3...multiplicity of 3

Is this an identity? <br> 1+sec^2x=tan^2x
amid [387]
No, the correct identity is \tan^2(x)+1=\sec^2(x). It is obtained by dividing the both sides of the Pythagorean Trigonometric Identity by cos²(x):

\sin^2(x)+\cos^2(x)=1\\\\&#10;\dfrac{\sin^2(x)+\cos^2(x)}{\cos^2(x)}=\dfrac{1}{\cos^2(x)}\\\\&#10;\dfrac{\sin^2(x)}{\cos^2(x)}+\dfrac{\cos^2(x)}{\cos^2(x)}=\dfrac{1}{\cos^2(x)}\\\\&#10;\boxed{\tan^2(x)+1=\sec^2(x)}~~\blacksquare
