If f(x)=(x+1)(x-2)(x-3) represent a student's displacement from school, what changes would g(x)=-0.5(x-9)(x-12)(x-13)+6 entail?
shepuryov [24]

Answer:

<em>c) Going half the distance, going in the opposite direction, starting 10 minutes later and starting 6 miles further.</em>

Step-by-step explanation:

<u>Function Modeling</u>

Let's take a look at both functions provided by the problem:

f(x)=(x+1)(x-2)(x-3)

g(x)=-0.5(x-9)(x-12)(x-13)+6

We are told that f(x) represents a student's displacement from school. We notice the following changes in g(x) with respect to f(x)

  • All the expressions in parentheses represent a displacement of -10 units in x. If x is time, then in g(x), the time is 10 minutes later than in f(x)
  • The factor that multiplies the three parentheses is 1 in f(x) and -0.5 in g(x). If that factor is the speed, then in g(x) the speed is half the speed in f(x) and in the opposite direction. The distance will be half of the distance of f because the student moves slower.
  • g(x) has an offset of +6, meaning the object is initially 6 miles further.

The option that collects all the conditions observed in both functions is:

c) Going half the distance, going in the opposite direction, starting 10 minutes later and starting 6 miles further

Consider the following two loans for P=$12,000.
n200080 [17]

Answer:

Simple interest-?

Step-by-step explanation:

P= 12000

T=5yrs

R=5%

Now,

Simple interest - PTR/100

= 12000*5*5/100

= $3000

Again,

P=12000

T=3yrs

R=8%

Now,

Simple interest - PTR/100

= 12000*3*8/100

= $2880

Hope this helps.

Given the data below:
Leno4ka [110]

Answer:

5.16

Step-by-step explanation:

Since after x=3, value of y starts decreasing for increasing values of x, let's choose. Also we need to find f(x) for x=3.4

x=3,4,5 and f(x)=7,3,1 to find lagrange polynomial

P(x)= ((x-x2)(x-x3)y1)/((x1-x2)(x1-x3) + ((x-x1)(x-x3)y2)/((x2-x1)(x2-x3) + ((x-x1)(x-x2)y3)/((x3-x1)(x3-x2)

P(x)= ((x-4)(x-5)7)/((3-4)(3-5)) + ((x-3)(x-5)3)/((4-3)(4-5)) + ((x-3)(x-4)1)/((5-3)(5-4))

P(x)= x² -11x+31

P(3.4)= 5.16

The perimeter of a shape is 25.71 cm calculate the value of the radius X takes pie to be 3.142
Mariulka [41]

Answer:

5 cm

Step-by-step explanation:

Given a semicircle with perimeter 25.71 cm, we are required to find the radius of the circle.

Circumference of a Semicircle

=Length of the Circular part+Length of the diameter

=\pi r+2r

If \: \pi=3.142, C=25.71\\Then:\\25.71=3.142r+2r\\r(3.142+2)=25.71\\5.142r=25.71\\r=25.71 \div5.142\\r=5cm
