lawyer [7]

Let
x be the distance that the truck has left to travel
t be the the time

The total distance is 1675 miles
The average speed is 55 miles per hour

The equation that represents the distance that the truck has left to travel with respect to time is
55t + x =1675
x = -55t + 1675

What is the slope of a line perpendicular to the line whose equation is 2x+8y -64 Fully reduce your answer.

Lelechka [254]

Answer: I am pretty sure it is y=-1/4x-8. Hope this helps!

Step-by-step explanation:subtract the 2x from both sides which gives you 8y=-2x-64. Then you want to divide both sides by 8 to get y=-1/4x-8

Determine whether or not F is a conservative vector field. If it is, find a function f such that F = ∇f. (If the vector field is

gavmur [86]

$\nabla f=(ye^x+\sin y)\,\vec\imath+(e^x+x\cos y)\,\vec\jmath$

then

$\dfrac{\partial f}{\partial x}=ye^x+\sin y\implies f(x,y)=ye^x+x\sin y+g(y)$

Differentiating with respec to $y$ gives

$\dfrac{\partial f}{\partial y}=e^x+x\cos y=e^x+x\cos y+g'(y)$

$\implies g'(y)=0\implies g(y)=C$

So $F$ is indeed conservative, and

$f(x,y)=ye^x+x\sin y+C$

Q #7 please solve the equation

pishuonlain [190]

The relation between a and s is given to be:

a = 640s

where,

a = number of acres
s = number of square miles

We are to find the number of acres for 7.5 square miles.

This means, s = 7.5

Using the value in the formula, we get:

a = 640 x 7.5 = 4800 acres

So the answer to this question is option B

The smallest integer that can be added to -2m3 − m + m2 + 1 to make it completely divisible by m + 1 is .

dangina [55]

Recall the polynomial remainder theorem: if $m-c$ is a factor of some polynomial $p(m)$ , then the remainder upon dividing $p(m)$ by $m-c$ is $p(c)$ .

Let $c=-1$ and $p(m)=-2m^3+m^2-m+1$ . The remainder left from dividing $p(m)$ by $m+1$ is

$p(-1)=-2(-1)^3+(-1)^2-(-1)+1=5$

If we subtract 5 from both sides, we'd get a "remainder" of 0, which suggests that we have to add -5 to $p(m)$ to make $m+1$ a factor.
