Answer:

$\bold{x_1=-\dfrac{3+\sqrt{41}}{2}\approx-4.7\ ,\quad x_2=-\dfrac{3-\sqrt{41}}{2}\approx1.7}$

Step-by-step explanation:

$-2x^2-3x+4=0\\\\a=-2\,,\ b=-3\,,\ c=4\\\\\\x=\dfrac{-b-\sqrt{b^2\pm4ac}}{2a}=\dfrac{-(-3)\pm\sqrt{(-3)^2-4(-2)(4)}}{2(-1)}=\dfrac{3\pm\sqrt{9+32}}{-2}\\\\\\x_1=-\dfrac{3+\sqrt{41}}{2}\approx-4.7\ ,\qquad x_2=-\dfrac{3-\sqrt{41}}{2}\approx1.7$

A boat's value over time is given as the function f(x) and graphed below. Use A(x) = 400(b)x + 0 as the parent function. Which g

ser-zykov [4K]

Answer:

Please see attached graph

Step-by-step explanation:

We know that the equation tht represents the boats avlue is given by

A(x) = 400(b)^x + 0 = 400(b)^x

A(x) = 400(b)^x

An increment in the rate of 25% a yeard is given by

b = 1.25

A(x) = 400(1.25)^x

Which graph can be seen below

three times a number is three more than twice the number which equation can be used to find the value of X the unknown number

Lyrx [107]

Let the value of the number be represented as x.

Then, write out an equation;

3x=2x+3 <--- Solve for x now
3x-2x=3
x=3

Therefore the number is 3.

Hope I helped :)
