First let's reduce the feet to miles

there are 5280 feet in a mile therefore

26400 feet=5 miles

31680 feet=6 miles

Jet A(the first jet) descends 5 miles in 96 miles

Jet B(the second jet) descends 6 miles in 120 miles

We can compare these as fractions to see which is steeper. This can be viewed as slope and the origin (0,0) is the airport.

slope: 6/120=?=5/96

1/20=?=5/96

Now we know that 5/100 =1/20 so 5/96 must be bigger than 5/100 because you are dividing by a smaller number.

so 1/20<5/96

So Jet B is descending steeper than Jet A.

As for linear model, I don't exactly know what your teacher means but I think I actually used the linear model when I'm thinking of steepness as slope in the coordinate plane, I will include a picture.

In this extremely zoomed out graph, you can see the blue line is just slighly higher than the red line(slope as in explanation is way easier to tell) this could be seen as the linear model) :) Hope it helped!

A scientist writes the equation n(h)100e^0.25h to model the growth of a certain bacteria in a petri dish, where N represents the
Natasha2012 [34]

Answer: Second option is correct.

Step-by-step explanation:

Since we have given that

n(h)=100e^{0.25h}

where, N represents the number of bacteria after 'h' hours.

So, we have given that there are 450 bacteria present.

N = 450

According to question,

450=100e^{0.25h}\\\\\frac{450}{100}=e^{0.25h}\\\\4.5=e^{0.25h}\\\\\text{Taking natural log 'ln' on both sides}\\\\\ln (4.5)=0.25h\\\\1.50=0.25h\\\\h=\frac{1.50}{0.25}\\\\h\approx 6\ hours

Hence, Second option is correct.

Given linear function, y = -2/3X + 5 <br> What is the slope?
Vikki [24]

Answer:

The slope is -\frac{2}{3}.

Step-by-step explanation:

The equation is conveniently in slope-intercept form.

y=mx+b

m - slope

b - y-intercept

-2/3 is in m's spot, so it is the slope of the equation.

y=\boxed{m}x+b\\\\y=\boxed{-\frac{2}{3}}x+5

Hope this helps.

artcher [175]

Answer:

91p^{1+3q^{2r}}q^{2r^3}

Step-by-step explanation:

  (-7pq^2r^3) * (-13p^3q^2r)

= 91p^{1+3q^{2r} }*q^{2r^{3} }

= 91p^{1+3q^{2r}}q^{2r^3}
