An object is thrown from a platform. Its height (in meters), x seconds after launch, is modeled by h (x) = -5 (x + 1) (x -9)

Answer:

Step-by-step explanation:

This is already factored for us, which is really nice, so now all we need to do is apply the Zero Product Property to the sets of parenthesis and solve for x, which will give us the 2 times that the object is on the ground.

x + 1 = 0 so

x = -1

x - 9 = 0 so

x = 9

We all know that time cannot ever be negative, so the time that the object is on the ground is 9 seconds after it's launched (which was from an initial height of 45 meters).

I tried many times to solve this question: Joy makes 6,5 litres soup correct to the nearest 0.5 litres. She serves the soup in 2
Paraphin [41]

Joy makes 6.5 litres soup correct to the nearest 0.5 litres. She serves the soup in 280ml portions correct to the nearest 10ml. 22 people order this soup. Does joy definitely has enough soup to serve the 22 people.

Answer:

Yes, Joy definitely does has enough soup

Step-by-step explanation:

From the question, we know,

Joy make 6.5 litres of soup

Serves it in 280ml portions

Step 1

We convert the portions to liters

1 ml = 0.001 litre

280 ml

= 280ml × 0.001 litre/1 ml

= 0.28litre

Step 2

We divide 6.5 liters by 0.28 to find out how many people can be served

= 6.5 ÷ 0.28

= 23.2142857143 people

We can see that 6.5 liters soup can serve 23 people approximately.

Therefore, Yes, Joy definitely does has enough soup to serve 22 people

Consider the following statement: ∀ a, b, c ∈ Z, if a − b is even and b − c is even, then a − c is even.
kirill115 [55]

Answer Step-by-step explanation:

Given statement if a-b is even and b-c is even then a-c is even .

Let p: a-b and b-c are even

q: a-c is even.

Converse: If a-c is even then a-b and b-c are both even.

Inverse:If a-b and b-c  are not both even then a-c is not even.

If a= Even number

b= Even number

c=Even number

If a-c  is even then a-b and b-c are both even..Hence, the converse statement is true.

If a=Odd number

b=Odd number

c= Odd number

If a-c is even then a-b and b-c are both even number .Hence, the converse  statement is true.

If a=Even number

b= Even number

c= Odd number

a-b  and b-c are both odd not even number but a-c is even number

a=8,b=6 c=3

a-b=8-6=2

b-c=6-3=3

a-c=8-3=5

If a-c is odd then a-b even but b-c is odd .Hence , the converse statement is false.But the inverse statement is true.

If a= Odd number

b=Even number

c= Even number

If a-b is odd and b-c is even then a-c is odd not even . Hence, the inverse statement is true.

If a= Odd number

b=Eve number

c=Odd number

a=9,b=6,c=5

a-b=9-6=3

b-c=6-5=1

a-c=9-5=4

Here, a-b and b-c are not both even but a-c is even .Hence, the inverse statement is false.
