Is it possible for an exponential equation to have no solutions? If so, give an example. If not, explain why.

1 answer:

4 0

A function f(x) has solutions if we can find a value to plug in that leads to 0. In other words, there are solutions to f(x) = 0. Another term for "solution" is "root" or "x intercept"

An exponential function may cross the x axis at one point only. Though there are plenty of cases when there are no solutions at all. For instance, in the case of f(x) = (2^x) + 10

The right hand side will never be equal to zero no matter what you plug in for x. The graph will never cross the axis.

To answer your question, yes it is possible to have an exponential equation to have no solutions.

Without using a trigonometric ratio, find the distance from the ship to the buoy, B. Round the distance to the nearest tenth of

alexdok [17]

Without using the trigonometry ratio, we can find the distance between the ship and the buoy by:

the distance between City and Lemont SUBTRACT the vertical distance between City and the point parallel to the Ship

The distance between the City and Lemont can be worked out using the Sin rule
$\frac{57.8}{sin(36)}= \frac{City-Lemont}{sin(92)}$
$City-Lemont= \frac{57.9sin(92)}{sin(36)} = 98.27.....$ ≈98.3

The vertical distance between the City and the point parallel to the ship can be worked out using the Pythagoras theorem
$\sqrt{57.8^{2}- 44.6^{2} } =36.765...$ ≈36.8

The distance between the ship and the Buoy is given:
$98.3-36.8=61.5$ miles

Leah is having a brunch. She wants to serve her guests 2 gallons of juice that is 75% orange juice and 25% pineapple juice. She

Katen [24]

She wants to serve --------- > 2 gallons of juice that is 75% orange juice and 25% pineapple juice

then

2*0.75------------------ > 1.5 gallons of orange juice

2*0.25------------------ > 0.5 gallons of pineapple juice

2 gallons------------ >1.5 gallons of orange juice+ 0.5 gallons of pineapple juice

if 1 gallons pineapple juice mixture--------------------- > 0.40 gallons pineapple juice

X------------------------------------------------------------------- > 0.50 gallons pineapple juice

X=50/40=1.25 gallons juice mixture

1.25 mixture gallons---- > 0.50 gallons pineapple juice+0.75 gallons orange juice

Therefore

(2-1.25)=0.75 gallons of orange juice

2 gallons------------ >0.75 gallons of orange juice+ <span>1.25 mixture gallons </span>

0.75*(p)+1.25*(m)=2--------------- > (0.75/1.25)*(p)+(1.25/1.25)*m=2/1.25

0.60p+m=1.6

The answer is 0.60p+m=1.6
