Rebecca has been planting young trees in her garden. The maple tree that is 10 centimeters tall
is growing 2 centimeters per month, whereas the oak tree that is 15 centimeters tall is
growing 1 centimeter per month. In a few months, the two trees will be the same height. How
many months will this take and what will that height be?

Answers

Answer:

It will take 5 months and that height will be 20cm.

Step-by-step explanation:

Let the height of the tree be h cm and the number of months be m.

Maple tree

Initial height= 10cm

Total height= 10cm +2(number of months)

h= 2m +10 -----(1)

Oak tree

Initial height= 15cm

Total height= 15cm +1(number of months)

h= m +15 -----(2)

When the height of the two trees are the same,

2m +10= m +15

Solve for m:

2m -m= 15 -10

m= 5

Substitute m=5 into either equation 1 or 2 to obtain the height.

When m=5,

h= 5 +15

h= 20

Given the equation y = 12x − 25, describe a real-life context that could be modeled by the equation and describe the meaning of the coefficient, variable, and constant term expressed in the equation.

Answers

Answer:

Kindly check explanation

Step-by-step explanation:

Given the equation :

y = 12x − 25

The initial depth of groundwater being held by a storage tank which extends downward below the ground surface is - 25. The rate of change in depth the groundwater per unit of Rainfall is 12. Hence, a linear model which could model the depth of water in the tank in the described scenario is ;

y = 12x − 25

The rate of change in depth of ground water, y per unit change in number of Rainfall, x gives the slope Coefficient, which equals 12

The intercept value, which is the initial depth of groundwater before, it started raining is - 25

Does anyone know how to solve this?

Answers

9514 1404 393

Answer:

Step-by-step explanation:

The tangent of the angle can be found using the identity for the tangent of the difference of angles.

  tan(α-β) = (tan(α) -tan(β))/(1 +tan(α)tan(β))

The tangent of the angle of each vector is the ratio of the j coefficient to the i coefficient.

  tan(α) = -2/3

  tan(β) = 4/7

  tan(α-β) = (-2/3 -4/7)/(1 +(-2/3)(4/7))

  = (-14-12)/(21 -8) = -26/13 = -2

Then the magnitude of the angle between the vectors is ...

  arctan(2) ≈ 63.43°
