Solution:

<u>Note that:</u>

  • Given equation: 4(k + 1) = k + 10
  • To find: 3k

<u>Simplifying the LHS:</u>

  • 4(k + 1) = k + 10
  • => (4 x k) + (4 x 1) = k + 10
  • => 4k + 4 = k + 10

<u>Subtracting k and 4 both sides:</u>

  • 4k + 4 - k - 4 = k + 10 - k - 4
  • => 3k = 6 (No further solution required)

The value of 3k is 6.

The distance traveled by a toy car can be modeled by D(t) = t3 − 3t2 + t − 3, where t &gt; 3 represents time in seconds. If the
Bogdan [553]

Answer:

t^2+1

Step-by-step explanation:

We are given that

Distance traveled by a toy car

D(t)=t^3-3t^2+t-3

Where t>3

Time taken by car =t-3 seconds

We have to find the expression which represents the speed of the toy car.

We know that

Speed=\frac{Distance}{time}

Using the formula

Speed=\frac{(t^3-3t^2+t-3)}{t-3}

Speed=\frac{t^2(t-3)+(t-3)}{t-3}

Speed=\frac{(t-3)(t^2+1)}{t-3}

Speed=t^2+1

Hence, the expression  which represents the speed of the toy car

t^2+1

Parabola skate rental rents skate boards for $4.50 per hour with a rental fee of $35. Arc Hawk Skat rental rents skate boards fo
mel-nik [20]

Answer:

Variable: h is hours and r is the rental costs

Two equations are:

For Parabola Skate rental company; r =4.50h + 35

For Arc Hawk Skate rental company; r =5.25h + 25

Rate of change for each company:

Parabola:  rate of change is, 4.50 per hours

Arc Hawk: rate of change is, 5.25 per hours

Step-by-step explanation:

Let h represents the hours and  r represents the rental costs.

Parabola Skate rental company: rents skate boards for $4.50 per hour with a rental fee of $35.

⇒ r =4.50h + 35

Arc Hawk Skate rental Company: rents skate boards for 5.25 per hour with a rental fee of $25.

⇒  r =5.25h + 25

To find the rate of change for each rental company:

Rate of change states the rate that describes how one quantity changes in relation to another quantity.

If y is the dependent variable and x is the independent variables

then,

y=mx+b ; where m is the slope or rate of change.

In this question, rate of change(m) represents the costs per hour to rent the skate boards.

  • For Parabola Skate rental company:

Rate of change = 4.50 per hour

  • For Arc Hawk Skate rental company:

Rate of change = 5.25 per hour
