Find the area between the graph of the given function and the x-axis over the given interval, if possible.

icang [17]

Answer:

Not possible to find out area

Step-by-step explanation:

Given is an exponential function as

$f(x) =e^{-x}$ and we have to find the area to the left of e above x axis under the curve.

Using integrals, we find area =

$\int\limits^e_{-\infty} e^{-x} \, dx\\=-e^{-x}$

substitute limits

When we substitute -infinity we get e^infty which is again infinity

Hence finding out area is not possible.

The integral of area diverges.

The answer to this problem

Ksivusya [100]

Answer:

B. $\frac{7\sqrt{2}}{34}$

Step-by-step explanation:

Cos θ = Adjacent/hypotenuse

Adjacent = 7

Hypotenuse = √(23² + 7²) = √578 = 17√2

Thus:

Cos θ = $\frac{7}{17\sqrt{2}}$

Rationalize

Cos θ = $\frac{7*\sqrt{2}}{17\sqrt{2}*\sqrt{2}}$

Cos θ = $\frac{7\sqrt{2}}{17*2}$

Cos θ = $\frac{7\sqrt{2}}{34}$

Evaluate the expression: 3a+4 a = 1.5 a = 1/3 a = 2

Nana76 [90]

Answer:

mathpapa.com

the place i got this from tbh i don't understand what you want for an answer but i tried, so here is a website that i got these from i hope it helps you.

Step-by-step explanation:

Evaluate for a= 1/3

3(1/3)+4(1/3) = 7/3

Evaluate for a= 1.5

(3)(1.5)+(4)(1.5)

=10.5

Evaluate for a=

(3)(2)+(4)(2)

=14
