Answer 2

Answer:

X^2+11x+28

Step-by-step explanation:

FOIL = First, Outer, Inner, Last

First: x times x= x^2

Outer: x times 7= 7x

Inner: 4 times x= 4x

Last: 4 times 7= 28

Since outer and inner are both positive you would add togther. Therefore answer is x^2+11x+28

cos 49° = 55 over x
tan 49° = 55 over x

Answers

yes it should be tan 49 degrees = x over 55

The answer is tan 49° = x over 55 (I got it correct on my quiz).

The function f(x)=2+e^x has an asymptote at ________.

Answers

Answer: Horizontal asymptote at y = 2

As x approaches negative infinity, the e^x term slowly approaches 0

This means 2+e^x approaches 2+0 = 2

So that's why we have a horizontal asymptote at y = 2

The graph approaches the line y = 2 but doesn't touch or cross it. Think of it like an electric fence.

i believe its 300

Step-by-step explanation:

Answer:

Heres my guess on it, he can feed around 301 people

Step-by-step explanation:

I think you would first find out how much it would cost to feed 1 person, which can be done by taking 18.45/3. It will equal around $6.15. then you would take that number and divide by the money he is willing to spend, which is 1850

(1850/6.15)

You get 300.81 which can round to around 301 people

Jane is hiking at an elevation of 142 feet above sea level she descends 325 feet into a valley. what is janes Elevation in feet in relation to a second hiker who is 24 feet below sea level?

Answers

Given parameters:

Elevation of hiking  = 142ft

Descent of Jane  = 325ft

Height of second hiker  = 24ft below sea level

Unknown:

Jane's elevation relative to the second hiker = ?

Solution:

The sea level here is the reference plane and the elevation here is zero;

   Jane                     142ft                          142ft above sea level    

                                                                ↓ Descent

          Seal level        0ft                            0ft                                 Second hiker

                                                                   183ft(below sea level)

The elevation of Jane in relation to the second hiker is 183 - 24 = 159ft below the second hiker.
