Mrs. Galicia bought a new car for $20,000. This car will depreciate at a rate of 6% per year. Which equation represents this fun

ction in terms of x, time.
f(x) = 200000(.06)"^x
f (x) = 20000(1.05)"^x
f(2)= 20000(6)"^x
f() = 200000(.94)"^x

Answer:

f(x) = 20,000(1 - 0.06)^x  ->  f(x) = 20,000 = (0.04)^x

Step-by-step explanation:

The equation to get exponential decay is: A = P(1 +- r)^t

A = Account Balance

P = Principle Amount

r = interest rate (decimal)

t = Time (years)

So, if you plug in all the variables with the values represented in the word problem, you get: f(x) = 20,000(1 - 0.06)^x

Hope this helps!

Answer:

65 cm

Step-by-step explanation:

See the attached image.  The Pythagorean Theorem says in a right triangle, (leg)^2 + (leg)^2 = (hypotenuse)^2.

16^2+63^2=x^2\\256+3969=x^2\\4225=x^2\\x=\sqrt4225}\\x=65

Which ordered pair would form a proportional relationship with the point graphed below? On a coordinate plane, a line with negat
avanturin [10]

Answer:

Answer:

(5, 20)  

Step-by-step explanation:

We can find the slope of the line

m = (y2-y1)/(x2-x1)

   = (40-0)/(10-0)

   = 40/10

   =4

Since the line goes through (0,0) the y intercept is 0

y = mx+b

y = 4x

Lets check the points  by substituting into the equation

40, 10)     10 = 4*40   10 =160  no

(–5, –10)    -10 = 4*-5    10 = -20   no

(5, 20)       20 = 4*5    20 = 20  yes

(–10, –20)    -20 = 4*-10    -20 = -40   no

Step-by-step explanation:

Which ordered pair would form a proportional relationship with the point graphed below? On a coordinate plane, a line with negative slope goes through points (negative 20, 10), (0, 0), and (20, negative 10). (10, –20) (–30, 20) (–10, 5) (35, –20)

What is the domain of the relation y = arccscx?
Stella [2.4K]

Answer:

y=arc\csc x

Step-by-step explanation:

The given function is y=arc\csc x.

The domain refers to all values of x for which this function is defined.

Recall that: the domain of y=arc \sin (x) is -1\le x\le1

And we know y=arc\csc x is the reciprocal of y=arc \sin (x).

Therefore the complement of the domain of y=arc \sin (x) which is (-\infty,-1]\cup [1,+\infty) is the domain of y=arc\csc x

Use the square root property of equality to solve (x  – 3)2 = –4. The solutions are a. -1 or 7 b. 1 or 5 c. 3+- 2i d. 3+-4i
makkiz [27]
The answer is C. 3+-2i

(x-3)(x-3)^{2} = -4

 \sqrt{(x-3)^2} = +- \sqrt{-4

x - 3 = i \sqrt{4} 

x - 3 = +-2i

x = 3 +-2i
