Answer:

Step-by-step explanation:

Future value with continuous compounding ; FV =Pe^{rt\\ } \\ 900,000 = 15,000e^{38r} \\ \\ \frac{900,000}{15,000}  =e^{38r\\ }\\ \\ \\ 60 =e^{38r}

Introduce <em>ln </em>on both sides of the equation

ln 60 = lne^{38r}

note:  lne^{x} = x

Next, solve the equation;

4.09 = 38r

Divide both sides by 38 to solve for r;

4.09/38 = r

r= 0.107746 or 10.7746%

Therefore the rate would be 10.775% to the nearest a tenth of a percent.

Solve the inequality 47. 75 x Less-than-or-equal-to 50 to determine how much more weight can be added to Li’s suitcase without g
vlada-n [284]

The value of x is less than or equal to 2.25.

<h2>Linear system</h2>

It is a system of an equation in which the highest power of the variable is always 1. A one-dimension figure that has no width. It is a combination of infinite points side by side.

<h3>Simplification</h3>

Simplification is to make something easier to do or understand and to make something less complicated.

Given

The expression is 47.75 + x ≤ 50.

<h3>To find</h3>

The value of x.

<h3>How to find the value of x?</h3>

The expression is 47.75 + x ≤ 50.

On simplifying,

47.75 + x ≤ 50

            x ≤  50 - 47.75

            x ≤ 2.25

Thus, the value of x is less than or equal to 2.25.

More about the linear system link is given below.

Are collinear points coplanar?
Anna35 [415]

collinear points are points in the same line, like

●-----------------●------------------------------------------●

and the line will always be contained by a plane, so since the line is in a plane, all points in it will also be in the same plane, and therefore be coplanar.

There’s a picture so I don’t have to type out the question
Lorico [155]

For this case we have the following function:

s (V) = \sqrt [3] {V}

This function describes the side length of the cube.

If Jason wants a cube with a minimum volume of 64 cubic centimeters, then we propose the following inequality:

s \geq \sqrt [3] {64}

Rewriting we have:

s \geq \sqrt [3] {4 ^ 3}\\s \geq4

Answer:

Option B
