Let Sam be (S+8) years while his sister is S years.

S(S+8) = 105

S^2+8S-105 = 0

(S+15)(S-7) = 0

Sam’s sister is 7 years and Sam is 15 years old.

a cyclist bikes a certain distance in 45 minutes , write an equation that shows the relationship between speed,s, and time,t, wh
denis23 [38]

An equation that shows the relationship between speed and time is Speed = \frac{100}{45}

<u>Given the following data:</u>

  • Distance = 100 miles.
  • Time = 45 minutes.

To write an equation that shows the relationship between speed and time:

<h3>What is speed?</h3>

Speed can be defined as the distance covered by a physical object per unit of time. Thus, the cyclist's speed can be measured as miles per minutes.

Mathematically, speed is given by this formula;

Speed = \frac{distance}{time}

Substituting the given parameters into the formula, we have;

Speed = \frac{100}{45}

xxMikexx [17]

Answer:

Dimensions of rectangle : Width = 2x , Length = 49 - x^2

Area of Rectangle = 98x - 2x^3

Step-by-step explanation:

A rectangle constructed with its base on the​ x-axis and two of its vertices on the parabola

Supposing coordinates of upper right vertex of rectangle are P = (x,y)

Due to parabola symmetry, width of rectangle is twice the horizontal (X) axis distance between Y axis & point P.

Width of rectangle :  2x

Length of rectangle :  y = 49 - x^2

Area of Rectangle = Length x Width

(2x) (49 - x^2)

= 98x - 2x^3
