Determine the derivative of the following and leave the answer with positive exponentsAy/ax if y=5x+√x to the exponent 5/2x²

Answers

Hello,

It was a long time i have done this.

y=(5x+√x) ^(2.5 x²)

ln y= 2.5x² ln (5x+√x)

We use:
d (ln y)/dx=1/y* dy/dx

y'/y= 5x*ln(5x+√x)+2.5x²*1/(5x+√x) *(5+1/(2√x))

y'=(5x+√x) ^(2.5 x²)*[5x*ln(5x+√x)+2.5x²*1/(5x+√x) *(5+1/(2√x))]

The width,w, of a rectangular garden is X -2 the area of the garden is X^3-2X-4 what is an expression for the length of the garden? A. X^2-2x-2
B. X^2+2x-2
C. X^2-2x+2
D. X^2+2x+2

Answers

Answer:

D.x^2+2x+2

Step-by-step explanation:

We know that,

The area of a rectangle is,

A = l × b,

Where, l is the length of the rectangle,

w is the width of the rectangle,

Given,

A = x^3-2x-4

w=(x-2)

By substituting values,

x^3-2x-4=(x-2)l

\implies l = (x^3-2x-4)/(x-2)=x^2+2x+2 ( By long division shown below )

Hence, the length of the rectangular garden isx^2+2x+2

Option D is correct.

A=lw \Rightarrow l=(A)/(w)
A - area, l - length, w - width

w=x-2 \nA=x^3-2x-4 \n \nl=(x^3-2x-4)/(x-2)=(x^3-2x^2+2x^2-4x+2x-4)/(x-2)=(x^2(x-2)+2x(x-2)+2(x-2))/(x-2)= \n=((x^2+2x+2)(x-2))/(x-2)=x^2+2x+2

The answer is D. x²+2x+2.

What is the perimeter of a rhombus-shaped street sign with a 35-cm side? A. 280 cm
B. 140 cm
C. 1,225 cm
D. 70 cm

Answers

A rhombus has a total of 4 sides. All sides are equal. The formula of getting the perimeter of  a rhombus is:
Perimeter = 4 * S
Perimeter = 4 * 35 cm
Perimeter = 140 cm.

So the perimeter of a rhombus-shaped street sign that has a 35-cm side is equal to (B) 140 cm.

Which expression gives the surface area of a sphere with radius r?A. r2
B. 4r3
C. 4r2
D. 4r2

Answers

The surface area of a sphere is the area of four great circles . . .  4 π r²  .

Apparently, either 'C' or 'D' was supposed to be the correct choice,
but the  π  got lost  in the pantry on the way to the printer.

Answer:

Area of sphere is given by 4\cdot \pi\cdot r^2

Step-by-step explanation:

The surface area of sphere is given by:

\text{Area of sphere}=4\cdot \pi\cdot r^2

Option C and D are correct but \pi is missing in the options

Option A and B are incorrect.

\pi=3.14 to solve the area of sphere when radius is given a constant value.

Given: PQ congruent to SR, PQR congruent to SRQ

Answer:

ΔPQR is congruent to ΔSRQ b the Side-Angle-Side rule of congruency   {}    

Step-by-step explanation:

The two column proof is given as follows;

Statement    {}                                         Reason

1. \overline {PQ}\overline {SR}      {}                                      Given

2. ∠PQR ≅ ∠SRQ   {}                               Given

3. \overline {QR}\overline {QR}      {}                                     By reflexive property

4. ΔPQR ≅ ΔSRQ   {}                               By SAS rule of congruency   {}          

When two sides and an included angle of one triangle are congruent to the corresponding two side and an included angle of another triangle, both triangles are said to be congruent by the Side-Angle-Side SAS rule of congruency.
