Answer:

(-1.22,- 6.89)

Step-by-step explanation:

The vector F lies in the IVth quadrant so the values of x and y components will be negative .

Considering the origin O and  F making an angle ∅ of 10° with the x- axis at X . Δ XOF is a right angled triangle with right angle at XF. Let XF be the perpendicular OX base and OF  hypotenuse c= 17.

So the rectangular components Fx and Fy can be found by the following formula

Sin∅ = Perpendicular/ Hypotenuse

Perpendicular = sin∅ * hypotenuse

Fy= sin - 10° *7

Fy =- 0.17364*7= -1.21554 ≅  -1.2155 ≅  -1.22

Base/ Hyptenuse= Cos∅

Base= Cos ∅ *Hypotenuse

Fx= Cos -10 ° *7= -0.98480 *7= - 6.8936 ≅   -6.894 ≅   -6.89

The rectangular components of F are Fx along x- axis and Fy along y- axis having values  equal to 1.22 and 6.89  and since they are in the fourth quadrant their values are negative

Find each of the following for ​
KATRIN_1 [288]
<h2>Answer:</h2>

(a)

          f(x+ h)=8x+8h+3  

(b)

            f(x+ h)-f(x)=8h          

(c)

             \dfrac{f(x+ h)-f(x)}{h}=8

<h2>Step-by-step explanation:</h2>

We are given a function f(x) as :

              f(x)=8x+3

(a)

           f(x+ h)

We will substitute (x+h) in place of x in the function f(x) as follows:

f(x+h)=8(x+h)+3\\\\i.e.\\\\f(x+h)=8x+8h+3

(b)

       f(x+ h)-f(x)              

Now on subtracting the f(x+h) obtained in part (a) with the function f(x) we have:

f(x+h)-f(x)=8x+8h+3-(8x+3)\\\\i.e.\\\\f(x+h)-f(x)=8x+8h+3-8x-3\\\\i.e.\\\\f(x+h)-f(x)=8h

(c)

           \dfrac{f(x+ h)-f(x)}{h}            

In this part we will divide the numerator expression which is obtained in part (b) by h to get:

           \dfrac{f(x+ h)-f(x)}{h}=\dfrac{8h}{h}\\\\i.e.\\\\\dfrac{f(x+h)-f(x)}{h}=8

Roots of x^2+8x+9 by finding in quadratic formula
gladu [14]
The quadratic formula is -b + or - the square root of b squared - 4 times the a value and c value over 2a. So the roots would be -1.354249 and -6.645751. I believe these are the roots.
