Answer:

-5x+2

Step-by-step explanation:

1. Multiply number 2 and 2=4 so it is

4-5x-2

2. Combine like terms

-5x+4-2

3. Subtract the numbers

-5x+2

A student designs a container to prevent an egg from breaking when dropped from a height of 30 feet. Write a function that gives
Rufina [12.5K]

Answer:

As i understand, you put an egg inside a container, and then you drop it from 30ft above the ground.

Now, when the container is in the air, the only force acting on it will be the gravitational force (we can discard things like the air resistance, as we do not know the shape or volume of the container).

The gravitational acceleration is g = 32.2ft/s^2

Then the acceleration of the container will be:

A(t) = -32.2ft/s^2

For the velocity, we need to integrate over time to get:

V(t) = (-32.2ft/s^2)*t + v0

where v0 is the initial velocity, as the container is "dropped", the initial velocity is zero, then:

V(t) = (-32.2ft/s^2)*t

For the position, or height in this case, we integrate again over time, and get:

P(t) = (1/2)*(-32.2ft/s^2)*t^2 + p0

Where p0 is the initial height, 30 ft in this case.

Then the equation for the height, as a function of time, is:

P(t) = (-16.1ft/s^2)*t^2 + 30ft.

Where the fact that the container is made in such a way that an egg inside of it does not break (For example, made of a really dense and elastic material that can absorb all the energy of the impact), does not change anything in this equation, as the kinematics do not depend on that kind of properties.

What is the measure of <4?
frez [133]

Answer:

25 degrees

Step-by-step explanation:

Angles 4 and 6 are supplementary angles since they as same side interior angles for parallel lines cut by a transversal. This means angle 4 + angle 6 = 180. If angle 6 is 155 then angle 4 must be 25 degrees

what is the recursive definition and explicit formula of the sequence 3, 5.5, 8, 10.5, 13, 15.5? I know the pattern is +2.5 ​
Delicious77 [7]

Answer:

a_{n} = a_{n-1} + 2.5

Step-by-step explanation:

This is an arithmetic sequence with common difference d = 2.5

The recursive formula allows any term in the sequence to be found by adding d to the previous term, thus

a_{n} = a_{n-1} + 2.5 ← recursive formula with a₁ = 3
