2. Mr. Frank tyses 12 emails per<br> day. How long will it take him to<br> write 60 emails?

Nezavi [6.7K]

Answer:

5 days

Step-by-step explanation:

We can use a ratio to solve

12 emails 60 emails

--------------- = --------------

1 day x days

Using cross products

12*x = 1 * 60

12x = 60

Divide each side by 12

12x/12 = 60/12

x =5

It will take him 5 days

The surface of a hill is modeled by z = 100 − 4 x 2 − 2 y 2 . When a group of hikers reach the point (-3,-2,56) it begins to sno

m_a_m_a [10]

Answer:

(-24, -8)

Step-by-step explanation:

Let us recall that when we have a function f

$\large f:\mathbb{R}^2\rightarrow \mathbb{R}\\f(x,y)=z$

<em>if the gradient of f at a given point (x,y) exists, then the gradient of f at this point (x,y) gives the direction of maximum rate of increasing and minus the gradient of f at this point gives the direction of maximum rate of decreasing</em>. That is

$\large \nabla f=(\frac{\partial f}{\partial x},\frac{\partial f}{\partial y})$

at the point (x,y) gives the direction of maximum rate of increasing

$\large -\nabla f$

at the point (x,y) gives the direction of maximum rate of decreasing

In this case we have

$\large f(x,y)=100-4x^2-2y^2$

and we want to find the direction of fastest speed of decreasing at the point (-3,-2)

$\large \nabla f(x,y)=(-8x,-4y) \Rightarrow -\nabla f=(8x,4y)$

at the point (-3,-2) minus the gradient equals

$\large -\nabla f(-3,-2)=(-24,-8)$

hence the vector (-24,-8) points in the direction with the greatest rate of decreasing, and they should start their descent in that direction.

2(a-2)=3(a-5) Distrubutive Property

Brrunno [24]

So in distributive property you multiply the outside number by the two inside so in this case 2(a) + 2(-2) = 3(a) + 3(-5)
Which will give you
2a+ - 4 = 3a + - 15
Or
2a-4=3a-15
Then if your solving for a your can subtract 3a from 2a giving you
- a-4=-15
Then add 4 to - 15
-a =-11
Then divide by negative 1 (this is so a isn't negative)
A=11
Hope this helps!
