If the positive z-axis points upward, an equation for a horizontal plane through the point \left(3,2,4\right) is

1 answer:

6 0

The equation of a (horizontal) plane through (3,2,4) is a plane that has a value of z=4 everywhere on the plane.
Therefore the equation of the required plane is z=4.

A child is flying a kite. If the string is pulled tight to its full length of 40 feet and is held at an angle of 71 degrees abov

Savatey [412]

Answer:

38feet high

Step-by-step explanation:

Given the following

Length of the string = 40feet (hypotenuse)

Angle of elevation = 71 degrees

Required

Height of the kite (opposite)

Using the SOH CAH TOA identity

Sin theta = opp/hyp

Sin 71 = H/40

H = 40sin 71

H = 40(0.9455)

H = 37.82

Hence the kite is 38feet high (to the nearest whole number)

You pull horizontally on a 50-kg crate with a force of 450 n and the friction force on the crate is 250 n. the acceleration of t

Hello AljakeVillena!

$\huge \boxed{\mathfrak{Question} \downarrow}$

You pull horizontally on a 50-kg crate with a force of 450 n and the friction force on the crate is 250 n. the acceleration of the crate is ?

$\large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}$

Given,

mass of crate = 50 kg
Force you pull it with = 450 N
Frictional force = 250 N
Acceleration = ?

__________________

Let's first find the total force/net force acting on the crate. The total force will be :-

450 N - 250 N = 200 N.

We subtracted the forces because both the forces act on opposite directions.

__________________

Now, let's find the acceleration of the crate. To find the acceleration we must divide the net force by the mass. So,..

Acceleration = Force/mass
a = F/m
a = 200/50
a = 4 m/s²

__________________

So, the acceleration of the crate is 4 m/s².

Can anybody explain to me what this question mean so it says "8 more than a number n is written ___________ in algebraic form"

Umnica [9.8K]

Answer:

They want you to put it into an expression so that it could be expressed. So, 8 more than n would be 8+n.

Hope This Helps!!! :D
