Use the equation y=1/3x-2<br> Draw a graph of the line, and identify the slope and Y intercept
xz_007 [3.2K]
I can't graph the equation for you, but I can tell you where the points will be. The y-intercept is easy; 1/3×0=0 and 0-2= -2. One of your points (the y-intercept) should be at (0,-2). To find another point is slightly trickier, but all you have to do here is find a multiple of three. For the simplest one, go to 3 on the x-axis. Then, apply the equation, y=1/3x-2. Your second point should lay at (3,-1). Then, just connect those two points and extend them to show that the line is continuous. Hope I could help!

Find the solution of the differential equation that satisfies the given initial condition. dy/dx = xe^y, y(0) = 0
Anna [14]
\dfrac{\mathrm dy}{\mathrm dx}=xe^y
e^{-y}\,\mathrm dy=x\,\mathrm dx
-e^{-y}=\dfrac{x^2}2+C

y(0)=0
\implies-1=C
\implies -e^{-y}=\dfrac{x^2}2-1
e^{-y}=1-\dfrac{x^2}2
-y=\ln\left(1-\dfrac{x^2}2\right)
y=-\ln\left(1-\dfrac{x^2}2\right)

______________________________

⚫We have to find out the value of 1 \frac{2}{3} \div 6

⚫So we have to convert it like this first,

\frac{5}{3} \div 6

⚫Do reciprocal to change the sign of divide into multiply

\frac{5}{3} \times \frac{1}{6}

⚫By doing this, we will get

\frac{6}{18}

Simplify this,

\frac{1}{3}

⚫⚫So our answer will be \frac{1}{3}

3. A utility pole is 38 ft tall. The pole creates a 53 ft shadow. What is the angle of elevation of the sun? Round your answer t
dybincka [34]

Answer:

The angle of elevation of the sun is 36\degree.

Step-by-step explanation:

Let x be the angle of elevation of the sun as shown in the diagram.


Then the side length which is 38 feet is opposite to x and the side length which is 53 feet is adjacent to x.


Therefore we use the trigonometric ratio that involves the opposite and adjacent sides, which is the tangent ratio.


\tan x=\frac{38}{53}


\Rightarrow \tan x=0.71698


We solve for x to get,


x=\arctan (0.71698)


\Rightarrow x=35.63981


To the nearest degree, the angle of elevation is 36\degree

Fifteen is no more than a number t divided by 5,What is the inequality?
Allisa [31]

An inequality may be used to model the given situation. The phrase, "no more than" implies "less than or equal to". Therefore, the inequality is:

15 ≤ t / 5

Solving the inequality of t, we get:

t ≥ 75

This means that the number t is at least 75 (the phrase at least implies greater than or equal to)

Hope this helps!
