Find the maxmium area of a rectangular plot of land which can be enclosed by rope of length 60 metres

mario62 [17]

Answer:

225 m²

Step-by-step explanation:

If W is the width of the rectangle, and L is the length, then:

60 = 2W + 2L

A = WL

Use the first equation to solve for one of the variables:

30 = W + L

L = 30 − W

Substitute into the second equation:

A = W (30 − W)

A = 30W − W²

This is a parabola, so we can find the vertex using the formula x = -b/(2a).

W = -30 / (2 × -1)

W = 15

Or, we can use calculus:

dA/dW = 30 − 2W

0 = 30 − 2W

W = 15

Solving for L:

L = 30 − W

L = 15

So the maximum area is:

A = WL

A = (15)(15)

A = 225

What is the scale factor from ALMN to AOPQ?

Nitella [24]

Answer:

Step-by-step explanation:

There 2 ways to interpret this problem.

From the info given:

These two triangles are congruent by SSS and congruent triangles have congruent or equal side lengths so the answer have to be 1.

If the triangles are similar, the side lengths form a proportion of that

$\frac{3}{3} = \frac{3}{3}$

So the ratio or scale factor is 1.

Shanice invests $5,887 in a retirement account with a fixed annual interest rate of 4% compounded 12 times per year. How long wi

qwelly [4]

Answer:

It takes 14 years for the account balance to reach $10,296.62

Step-by-step explanation:

Given:

Principal amount = $5,887

Rate of interest = 4% and 12 times per year

Balance amount = $10296.62

To find:

The time to reach $10,296.62 = ?

Solution:

We know that

$N(t) = N_0e^{rt}$

Here,

N(t) = 10,296.62

$N_0$ = $5,887

r = 4 % = 0.04

we have to find the t value

On substituting the given values

$10,296.62 = 5,887e^{0.04t}$

Taking ln to remove e we get

ln $ln(10,296.62) = ln(5887)({0.04t)$

$ln(\frac{10296.62}{5887}) = 0.04t$

ln(1.749) = 0.04t

$t = \frac{ln(1.749)}{0.04}$

$t =\frac{ 0.5590}{0.04}$

t = 13.97

t = 14
