Jane is standing at the base of a 6300ft tall mountain. If she climbs 15% of the remaining height each day, how many feet will s

Andrews [41]

Answer:

Total ft climbed= 3,011.36

Step-by-step explanation:

Giving the following information:

Total ft= 6,300

Climbing rate= 15% of the remaining height per day

Total ft climbed per day:

Day 1= 6,300*0.15= 945

Day 2= (6,300 - 945)*0.15= 803.25

Day 3= (5,355 - 803.25)*0.15= 682.76

Day 4= (4,551.75 - 682.76)*0.15= 580.35

Total ft climbed= 3,011.36

The ratio of adults to children on a train in 7:2. There are 245 adults on the train. Find the total number of people on the tra

Kruka [31]

Answer:

315 people

Step-by-step explanation:

Using the given ratio, we can figure out the number of children on the train by doing cross multiplication.

Let x = # of children on train.

7/2 = 245/x

7x = 490

x = 70 children

The total number of people = 70 + 245 = 315 people total

If f(x)=3 x -1 and g(x)=0.03x^3-x+1 an approximate solution for the equation f(x)=g(x) is

lubasha [3.4K]

Answer:

x ≈ {-11.789, +0.501, 11.288}

Step-by-step explanation:

The cubic g(x) - f(x) = 0 has three real solutions. It can be rewritten as ...

$g(x)-f(x)=0\\\\0.03x^3-x+1-(3x-1)=0\\\\0.03x^3-4x+2=0$

Since the solutions are irrational, they are best found using a spreadsheet or graphing calculator. My favorite graphing calculator shows the approximate solutions below.

Comment on the problem statement

Your expression for f(x) is ambiguous in that many Brainly questions have the exponentiation indicator replaced by a blank: 3 x -1 often means 3^x -1 and sometimes means 3^(x-1). We have taken the expression at face value and have assumed it is a linear expression. If otherwise, the problem is basically worked the same way: write a function h(x) = g(x) - f(x) and look for solutions to h(x) = 0. Graphing can be useful.
