<span>2t+8≥-4(t+7)
Use distributive property
2t+8</span>≥-4t-28
Subtract 2t from both sides
8≥-6t-28
Add 28 to both sides
36≥-6t
Divide -6 on both sides while flipping the inequality
Final Answer: -6<=t
1. Yes a circle is a two-dimensional figure. It lies in the plane, which is basically a flat piece of paper that doesn't bend or curve, and the paper extends infinitely in all directions.
2. A circle is <u>not</u> a polygon. A polygon has finitely many straight line segments that glue together to form an enclosed figure. Think of fencing in an area with straight fence portions.
3. Yes this is what makes a circle. Every point on the circle is the same distance from the center. We say these points on the circle are equidistant from the center.
We are told that a population of insects grows exponentially and we are given a table of data about insect population growth. We are asked to find population of insects at the end of week 11.
The initial insect population is 20 and at the end of 1st week population increases to 30.
Let us find growth percentage of insect population,
We can see that insect population is growing at rate of 50% per week.
Now let us write an exponential function for our population.
, where P(w) represents population at the end of w weeks.
Let us substitute w=11 in our function to find insect population at the end of 11 weeks.
Therefore, population of insects at the end of 11th week will be 1730.
Answer:
137.68
Step-by-step explanation:
Answer:21400
Step-by-step explanation: without tax=$20000
Tax=7%
Including tax=20000+7% of20000
That is 20000+7×20000/100=21400
So total cost is $21400
