<span>The relationship where p varies directly with d and inversely with the square root of u can be expressed as:
</span>
p = k1d
with k1 being the proportionality constant.
and p = k2\frac{1}{ \sqrt{u} }
where k2 serves as the proportionality constant.

By merging both equations, we find that p = C\frac{d}{ \sqrt{u} }
where K = K1*K2, with K being the proportionality constant.

Show that A(t)=300−250e0.2−0.02t satisfies the differential equation ⅆAⅆt=6−0.02A with initial condition A(10)=50 .
Leona [4166]

Detailed derivation:

dA/dt = 6 - 0.02A

dA/dt = -0.02 (A - 300)

Rearranging terms.

dA / (A - 300) = -0.02 dt

Integrate both sides.

ln(A - 300) = -0.02t + C

Isolate A.

A - 300 = Ce^(-0.02t)

A = 300 + Ce^(-0.02t)

Apply initial condition to determine C.

50 = 300 + Ce^(-0.02 × 10)

50 = 300 + Ce^(-0.2)

-250 = Ce^(-0.2)

C = -250e^(0.2)

A = 300 - 250e^(0.2)e^(-0.02t)

A = 300 - 250e^(0.2 - 0.02t)

What is the sum of the infinite geometric series? Sigma-Summation Underscript n = 1 Overscript 4 EndScripts (negative 144) (one-
PIT_PIT [3919]

Step-by-step explanation:

∑⁴ₙ₌₁ -144 (½)ⁿ⁻¹

This represents a finite geometric series where n equals 4, a₁ is -144, and r is ½.

S = a₁ (1 − rⁿ) / (1 − r)

S = -144 (1 − (½)⁴) / (1 − ½)

S = -270

If you wish to calculate the infinite sum (n = ∞):

S = a₁ / (1 − r)

S = -144 / (1 − ½)

S = -288

PIT_PIT [3919]
The expression in question is:

f(x) = x³ – 2x² – x + 2

To determine the roots, follow these steps:

1. Set the equation to zero:

0 = x³ – 2x² – x + 2

2. Factor the equation to get:

(x-2)(x-1)(x+1) = 0

3. The roots can be identified as follows:

x1 = -1
x2 = 1
x3 = 2

The area of ABED is 49 square units. Given AGequals9 units and ACequals10 ​units, what fraction of the area of ACIG is represent
Svet_ta [4321]

Answer:

The shaped region accounts for 7/18 of the area of ACIG.

Step-by-step explanation:

Refer to the attached diagram for further clarity on the problem.

Step 1

Determine the length of one side of square ABED.

We know that

AB=BE=ED=AD

The area of a square can be calculated as

A=b^{2}

where b is the side length.

We have

A=49\ units^2

So we substitute

49=b^{2}

b=7\ units

Thus,

AB=BE=ED=AD=7\ units

Step 2

Calculate the area of ACIG.

The area of rectangle ACIG is determined by

A=(AC)(AG)

Substituting the given values yields

A=(9)(10)=90\ units^2

Step 3

Determine the area of the shaded rectangle DEHG.

The area of rectangle DEHG is given by

A=(DE)(DG)

We find DE=7\ units

DG=AG-AD=9-7=2\ units

and substitute A=(7)(2)=14\ units^2

Step 4

Calculate the area of shaded rectangle BCFE.

The area of rectangle BCFE equals

A=(EF)(CF)

We see that

EF=AC-AB=10-7=3\ units

CF=BE=7\ units

and substitute

A=(3)(7)=21\ units^2

Step 5

Add the areas of the shaded regions together.

14+21=35\ units^2

Step 6

Divide the area of the shaded region by the area of ACIG.

\frac{35}{90}

Simplify this fraction by dividing both the numerator and denominator by 5.

\frac{7}{18}

Hence, the shaped region represents 7/18 of the area of ACIG.
