Answer:

y+(21)=-4(x-7)

Step-by-step explanation:

the point slope equation , two point

m=y2-y1/x2-x1

m=23+21/-4-7=44/-11= -4

y+(21)=-4(x-7)

What is the diagonal length of the TV, if it is 45.25 inches wide and 25.5 inches tall?
tatiyna

Diagonal length is a line from a left corner to a right in a rectangle or square.

Basically making two triangles.

You use the equation a^2+b^2=c^2

So 45.25^2+25.5^2=x^2

2,047.5625+650.25=x^2

2,697.8125=x^2

Then square root them both

51.9404707=x

And when rounding to the nearest number the diagonal length is 52 inches

Find the general solution of the following equation. Express the solution explicitly as a function of the independent variable.
Mashcka [7]

Answer:

Therefore the general solution is

2 \sqrt w = 2 ln(x) - 5 \frac1x +c

Step-by-step explanation:

Integration Rule:

  1. \int x^n dx= \frac{x^{n+1}}{n+1}+c
  2. \int \frac1x dx= ln(x) +c

Given differential equation is

x^2 \frac{dw}{dx}= \sqrt{w}(2x+5)

\Rightarrow x^2 dw= \sqrt{w} (2x+5) dx    [ multiplying dx both sides]

\Rightarrow \frac{dw}{\sqrt w}= \frac{(2x+5)}{x^2} dx                [ dividing x^2\sqrt w both sides]

Integrating both sides

\int \frac{dw}{\sqrt w}=\int \frac{(2x+5)}{x^2} dx

\Rightarrow \int w^{-\frac12} dw=\int (\frac{2x}{x^2}+\frac{5}{x^2} )dx

\Rightarrow \int w^{-\frac12} dw=\int \frac{2}{x}dx +\int\frac{5}{x^2} dx

\Rightarrow \frac{w^{-\frac12+1}}{-\frac12+1} =2ln x+5 \frac{x^{-2+1}}{-2+1}+c   [ c is arbitrary constant]

\Rightarrow 2 \sqrt w = 2 ln(x) - 5 \frac1x +c

Therefore the general solution is

2 \sqrt w = 2 ln(x) - 5 \frac1x +c

I need desperate help please!!
Reika [66]

Answer:

54°

Step-by-step explanation:

Formula we use,

→ Exterior angle + Interior angle = 180°

The required value of x will be,

→ 126° + x = 180°

→ x = 180° - 126°

→ [ x = 54° ]

Hence, the value of x is 54°.
