grandma gigi gave leyla a rare purple stone for her sweet 16 birthday. at that time,the stone was worth$245. it has been increas

This is a compound interest problem, therefore s(t) should be in the form:
s(t) = a(r)^{t}

where: 
t = time in years
s(t) = the value of your item after t years
a = the initial value of your item
r = rate

Therefore, we already know that a = 245$.

Now, we can calculate r:
r^{t}=\frac{s}{a}
r =  \sqrt[t]{ \frac{s}{a} }
r = \sqrt[5]{ \frac{560.50}{245} }
     = 1.18

Therefore, the correct answers are a = 245 and r = 1.18

F(x) = 3x² + 6x - 1

The graph is a parabola open upward (a= 3>0) with a minimum.

Calculate the vertex:

x = -b/2a → x = -6/(2.3) = -1. Then the axis of symmetry is x = - 1
Now to calculate the minimum, plugin the value of x:

y = 3x² + 6x - 1

y = 3(-1)² + 6(-1) -1

y= 3 - 6 -1 and y = - 4,

Ten the vertex (minimum) is at (-1,- 4)

Which statement is correct with respect to f(x) = -3|x − 1| + 12?
Talja [164]

Answer:

The V-shaped graph opens downward, and its vertex lies at (1, 12).

Step-by-step explanation:

  • first, plot the graph of f(x),
  • take some 5 random negative and positive x values and then find corresponding f[x] values.plot  f(x) on y-axis. now, plot these points on the graph and finally join all the points. this gives u the required graph.
  • I have plotted the graph and uploaded it.

refer it.

  • by seeing the graph, we can easily say that,The V-shaped graph opens downward, and its vertex lies at (1, 12).
