Answer:

ok me so basically

Step-by-step explanation:

the x axis is the one that goes left to right, so every number thats on the x side of the table, thats how far you go left or right. the y axis goes up and down so every number on the y side of the table is how much you go up and down. this problem is seeing if the graph corresponds with the table, it doesnt bc if it did, the part where it goes through the y axis would be right at 2 and up 0.

so basically with all that, no the table doesnt check out.

this was a very basic amateur explanation but if you have any questions i can answer them in the comments

Solve the initial value problem (explicit solution). y y' - cot t = 0 y(pi/2) = -1

Sergeu [11.5K]

This ODE is separable:

$yy'-\cot t=0\implies y\,\mathrm dy=\cot t\,\mathrm dt$

Integrate both sides to get

$\dfrac12y^2=\ln|\sin t|+C$

Given that $y\left(\frac\pi2\right)=-1$ , we get

$\dfrac12(-1)^2=\ln|\sin\dfrac\pi2\right|+C\implies C=\dfrac12$

Then

$\dfrac12y^2=\ln|\sin t|+\dfrac12$

$y^2=2\ln|\sin t|+1$

$y^2=\ln\sin^2t+1$

$\implies\boxed{y(t)=\pm\sqrt{\ln\sin^2t+1}$

The ratio of the length to the width of a map is 8 to 5. The map is exactly 32 inches in length. What is the width of the map? A

docker41 [41]

Ratio of length to width of a map = 8:5

Length of the map = 32 inches
Let the width of the map = x inches

So,

Length : Width = 8 : 5
32 : x= 8: 5

x = 5/8 * 32

x = 20 inches

So, the width of the map is 20 inches

HELPP PLSSSSSSSSSSSS

saul85 [17]

Answer:

6,-6,-26,-54

Step-by-step explanation:

f(p)=-4p^2+10

Now,putting the values of p into the function above,

when p=1, f(1)=-4(1)^2+10=6

for p=2, f(2)=-4(2)^2+10=-6

similarly,for p=3,4 the values will be respectively -26 and -54

Hope,this helps you.

Y intercept of graph

LenaWriter [7]

Answer:

Step-by-step explanation:

Basically the y - intercept is where the graph intercepts with the y axis. The y axis is the vertical line in the middle of the graph. As you can see, the the graph and the y axis intersect at about 4.
