Hello, there!

Answer:

<u><em>m=8 or 8=m</em></u>

*The answer must have a positive sign.*

Step-by-step explanation:

First, you had to divide by -5 from both sides of an equation.

\frac{-5m}{-5}=\frac{-40}{-5}

And, then simplify and solve equation.

40/5=8

m=8

Hope this helps!

Analyze the following categorical proposition by doing the following: (1) Identify the subject and predicate of each proposition
spayn [35]

Answer:

(1) Subject term: Bats and Predicate term: Mammals.

(2) A- Proposition

Step-by-step explanation:

Categorical proposition is a tool of deductive reasoning that involves two classes of objects. Coined by Ancient Greeks, categorical proposition asserts or denies whether one group contain all or some of the members of another group.

In the standard form of categorical proposition, the subject term comes first an the predicate term comes second. Hence, for the given sentence

<em>                                    </em>    <em>"</em><u><em>All bats are mammals</em></u><em>"</em>

The subject term is "bats" and the predicate term is "mammals". Furthermore, it is stated that all bats belong to the category of mammals. Thus, it is an example of proposition A(All S are P).

The height h in feet of a ball thrown vertically upward from the top of a 288-foot tall building is given by h=288+48t-16t^2 whe
mr Goodwill [35]

6 sec can take penny to strike the ground.

Solution:

Given data:

H_0=288 feet

V_0=48 feet

h(t)=288+48t-16t^2

Re-arrange the terms from greatest degree to smallest degree.

h(t)=-16t^2+48t+288

We can solve it by applying quadratic formula,

$x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}

Here a = –16, b = 48, c = 288

$t=\frac{-48\pm \sqrt{48^2-4(-16)(288)}}{2(-16)}

$t=\frac{-48\pm \sqrt{2304+18432}}{-32}

$t=\frac{-48\pm \sqrt{20736}}{-32}

$t=\frac{-48\pm144}{-32}

Now, write find two t's using plus and minus operation.

$t=\frac{-48+144}{-32},\ \ t=\frac{-48-144}{-32}

$t=\frac{96}{-32},\ \ t=\frac{-192}{-32}

t = –3 (or)   t = 6

We cannot write time is negative. so neglect t = –3.

Therefore t = 6.

Hence 6 sec can take penny to strike the ground.
