Answer:

i is always positive

Step-by-step explanation:

if be multiply 3 by 3 and get 9, then you multiply -2i by 2i and get -4i squared

9-4i^2 is now easy to solve unless we do now know the value of i, but since i is squared, i is always positive

Answer:

13

Step-by-step explanation:

Assuming this is (3-2i)(3+2i)

Use the FOIL method

First:       3(3) = 9

Outter:   3(2i) = 6i

Inner:     -2i(3) = -6i

Last:        -2i(2i) = -4i²

Add all of them together:

    9 + 6i - 6i - 4i²

=   9 - 4i²   =    9  - 4(-1)   =   9 + 4  =  13

*NOTE that i² = -1

Which statement is true about the local minimum of the graphed function
nasty-shy [4]

From the graph, we can see that the graph has bumps on (0,25) and (5.1, -7) coordinates.

The higher point is (0,25) and lower one is at (5.1, -7).

We need to find to find the interval of the local minimum and value of local minimum.

<em>From the graph, we can see that graph has local minimum is -7 in the interval [4,7].</em>

Therefore, correct option is 4th option.

<h3>Over the interval [4,7], the local minimum is -7.</h3>

A freight train from city A to city B and a passenger train from city B to city A left the cities at the same time, at 10:00 AM,
djyliett [7]

Answer: Both trains would meet at 1 pm

Step-by-step explanation:

Let t represent the time at which both trains will pass each other.

The distance between the cities is 360 miles. This means that by the time both trains meet, the total distance covered would be 360 miles.

Distance = speed × time

The freight train is travelling at 50 mph. Distance covered by the freight train in t hours is 50t.

The passenger train is travelling at 70 mph. Distance covered by the passenger train in t hours is 70t.

Since the total distance covered is 360 miles, it means that

50t + 70t = 360

120t = 360

t = 360/120

t = 3 hours

Both trains would meet at 1 pm

What is the force of a baseball that has a mass of 142 kg and has an acceleration of 30 m/s2?
salantis [7]

Answer:

The answer is

<h2>4260 N</h2>

Step-by-step explanation:

The force acting on an object when given the mass and acceleration can be found by using the formula

<h3>Force = mass × acceleration</h3>

From the question

mass = 142 kg

acceleration = 30 m/s²

So we have

Force = 142 × 30

We have the final answer as

<h3>4260 N</h3>

Hope this helps you
