What is the answer??????????????????????

Answer:

[tex]f(x) = \left \{ {{39.99; 0 \le x \le 450} \atop {0.45x - 162.51; \ x>450}} \right.[/tex]

Step-by-step explanation:

Given

Charges: $39.99 for first 450 minutes

Charges: $0.45 for additional minutes

(a): What is x

x represents the total minutes

(b): What is f(x)

f(x) represents the total monthly cellular charges

(c): The piecewise function

For the first 450 minutes, the function is:

[tex]f(x) = 39.99;\ 0 \le x \le 450[/tex]

For additional minutes.

In (a), the total minutes is x.

So, we have:

Total Charges = Charges for first 450 minutes + Charges for additional minutes * (Minutes after 450 minutes)

[tex]Total\ Charges = 39.99 + 0.45 * (x - 450)[/tex]

[tex]f(x) = 39.99 + 0.45 * (x - 450)[/tex]

Open bracket

[tex]f(x) = 39.99 + 0.45x - 0.45 * 450[/tex]

[tex]f(x) = 39.99 + 0.45x - 202.5[/tex]

Collect Like Terms

[tex]f(x) = 0.45x+39.99 - 202.5[/tex]

[tex]f(x) = 0.45x-162.51[/tex]

The range of the above function is: x > 450.

So, the piecewise function is:

[tex]f(x) = \left \{ {{39.99; 0 \le x \le 450} \atop {0.45x - 162.51; \ x>450}} \right.[/tex]

A and D.

Step-by-step explanation:

The main property of rhombi is that they have all four congruent sides.

So the only two quadrilaterals with four congruent sides are A and D.

Step-by-step explanation:

The Distributive Property is easy to remember, if you recall that "multiplication distributes over addition". Formally, they write this property as "a(b + c) = ab + ac". In numbers, this means, for example, that 2(3 + 4) = 2×3 + 2×4.

============================================================

Explanation:

I'm assuming points M and N are midpoints of segments FD and FE respectively. If that's the case, then segment DE is twice as long compared to segment MN. We consider MN to be a midsegment.

So,

DE = 2*(MN)

3x-2 = 2*(x+4)

3x-2 = 2x+8

3x-2x = 8+2

x = 10

Answer:

11 hours and 15 minutes (11.25)

Step-by-step explanation:

make a ratio

160:4.5

240/160=1.5

so 1 and 1/2 intervals of 4.5 hours

4.5+4.5= 9

4.5/2=2.25

9+2.25=11.25

The solution is 3.75 hours

The time taken by Jackie to drive a distance of 240 miles is given by the equation A = 3.75 hours

Speed is defined as the rate of change of position of an object in any direction. Speed is measured as the ratio of distance to the time in which the distance was covered. Speed is a scalar quantity as it has only direction and no magnitude

Speed = Distance / Time

Given data ,

Let the equation be represented as A

Now , the value of A is

Jackie drives 160 miles from Gary, Indiana to Indianapolis, Indiana in 2.5 hours

Distance = 160 miles

Time = 2.5 hours

So , the speed = distance / time

Substituting the values in the equation , we get

Speed = 160 / 2.5

Speed = 64 miles / hour

Now , the new distance = 240 miles

So , the Time required = Distance / Speed

Substituting the values in the equation , we get

Time required A = 240 / 64

Time required A = 3.75 hours

Therefore , the value of A is 3.75 hours

Hence , the time taken with a speed of 64 mph is 3.75 hours
