Answer:

Time (week 1 - week 10)

Step-by-step explanation:

Given

Measure of cost of gasoline over a period of time

Required

Determine what variable belongs to the horizontal axis

To answer this question, I'll re-echo the given parameters again

Measure of cost of gasoline over a period of time

This can be rephrased to be

Measure of cost of gasoline with respect to time

This means that the cost of gasoline is a function of time (10 weeks, to be precise).

Hence;

Cost will be on the vertical axis

Time will be on the horizontal axis

Conclusively,

The first option answers the question

Identify the initial amount a and the growth factor b in the exponential function.f(t)=1.4^t

vaieri [72.5K]

Initial amount is when no change has happened or when t=0
that iniital amoun tis 1
the growth factor
welll, it grows by 40% each time of previous times

I would say growth factor of 1.4

f(x)=a(b)^t
f(t)=1(1.4)^t
initial amount is 1
grouth factor is 1.4

An artist purchased 24 high quality canvases to be used for painting this fall. Each week she will allow herself to use three of

Nadusha1986 [10]

Answer:

canvases over weeks

Step-by-step explanation:

Given:

w(h) represents how many hours per week

c(t) approximates how many canvases she paints per hour

In function composition, if we have two function f(x) and g(x) then

(f.g)(x) or f(g(x)) means first apply g(), then apply f() i.e. applying function f to the results of function g.

Now we have c(w(h)), this means first we apply w(h) which will give us hours per week and then we'll apply function 'c' on the results of 'w' (that is number of hours for weeks painted). As result we'll get number of canvas per week!

Solve for x check your solution

abruzzese [7]

Area for a triangle is (1/2) bh or bh/2
So using this info, b = 1.5 m and h = x and A = 1.5 m^2

A = bh/2
1.5 = 1.5x/2
Multiply both sides by 2 to get rid of fraction ... 3 = 1.5x
Divide both sides by 1.5 ... 2 = x so x= 1.5 m
