Answer:

As t increases, the quantity reduces

Step-by-step explanation:

Given

f(t) = 1100(0.9945)^t

Required

What does the rate (0.9945) reveal about the function

From the given function, the rate b is:

b = 0.9945

When b has the following range:

0

Then, it means there is a reduction

<em>In other words, as the number of weeks (t) increases, the quantity (f(t)) reduces</em>

Convert 4500g to kilograms
Mazyrski [523]
To convert it to kilograms, you just divide by 1000 because 1000 grams are in a kilogram, so 4500 ÷ 1000 = 4.5kg. I hope this helps!

A number y increased by 5 is at least -21

             ❖ A number y increased by 5 is at least -21.

\diamond\large\blue\textsf{\textbf{\underline{\underline{Answer and how to solve:-}}}}

          ❖ First, if you come across the word "increased" it means we

    "increase" a number, or add something to that number, like

y increased by 5 \longmapsto \sf{y+5}

Now, we are also given that this expression is at least -21, which means it can't be -21; it can be -21 or it can be greater than -21.

So we have

\longmapsto\sf{y+5\geq -21}}

<em>Solving for y</em>

<em></em>

  •   Subtract 5 on both sides:-

\longmapsto\sf{y\geq -21-5}

\longmapsto\sf{y\geq -26}

So the values of y greater than or equal to -26 will make this inequality true.

<h3>Good luck with your studies.</h3>
