we can use formula

y=ab^x

now, we can find a and b

Initially , price is 500

so,

At x=0,y=500

500=ab^0

a=500

now, we can plug back

y=500(b)^x

At x=3,y=10

we can use it and find b

10=500(b)^3

now, we can solve for b

and we get

b=0.27144

so,

annual depreciation rate is 27.144%.......Answer

Solve the equation for principal values of x. Express solutions in degrees.
Hitman42 [59]

Option C:

x = 90°

Solution:

Given equation:

\sin x=1+\cos ^{2} x

<u>To find the degree:</u>

\sin x=1+\cos ^{2} x

Subtract 1 + cos²x from both sides.

\sin x-1-\cos ^{2} x=0

Using the trigonometric identity:\cos ^{2}(x)=1-\sin ^{2}(x)

\sin x-1-\left(1-\sin ^{2}x\right)=0

\sin x-1-1+\sin ^{2}x=0

\sin x-2+\sin ^{2}x=0

\sin ^{2}x+\sin x-2=0

Let sin x = u

u^2+u-2=0

Factor the quadratic equation.

(u+2)(u-1)=0

u + 2 = 0,  u – 1 = 0

u = –2, u = 1

That is sin x = –2, sin x = 1

sin x can't be smaller than –1 for real solutions. So ignore sin x = –2.

sin x = 1

The value of sin is 1 for 90°.

x = 90°.

Option C is the correct answer.

The graph of the function g(x)= x^2+3x-4 is shifted 5 units to the left
omeli [17]
<h2><em><u>HEYA</u></em></h2>

<h3>THE MID TERM SPLITTING OF THE EQUATION IS :</h3>

{x}^{2}  + 3x - 4

{x}^{2}  + 4x - x - 4

x(x + 4) - 1(x + 4)

x =  -4 \: and \: 1

x = 1

now shifted to 5 units left

therefore,

x=-4

If f(x) = 3a|4x - 4| - ax, where a is some constant not equal to zero, find f '(1)
dlinn [17]
The slope of an absolute function at the point where it evaluates to zero is undefined.
Here, when x=1, so |4x-4|=|4-4|=|0|, the slope is undefined.  This is where the vertex of the "V" on the graph of the absolute value function.
