Grace placed 3 strands bacteria in a petri dish. The bacteria strands triple every hour. Write a formula to
1 answer:
Answer:
a) The growth of bacteria at nth hour is :
b) At the end of the fourth hour, there are 81 stands of the bacteria
present.
Step-by-step explanation:
The number of initial bacteria in the dish = 3 strands
Rate at which bacteria multiply = 3 times every hour
So, the general form which represents the growth
As it multiplies three times every hour, so at nth hour:
The growth of bacteria at nth hour is :
Now, at n = 4, the growth of the bacteria is
= 3 x 3 x 3 x 3
⇒ = 81
So, at the end of the fourth hour, there are 81 stands of the bacteria present.

Your question states:
Suppose a car is traveling east on 4th Street and turns onto King Avenue heading northeast. What is the measure of the angle created by the car's turning? Explain your answer.
180</span>°-70°= 110° ✓
This person would be driving 110° degrees. ✓
So, what we would do it do 180° subtracted by 70. We need to find how much he turns onto King Avenue heading northeast. So we do 180° because that would be considered a full half turn, so 180° subtracted by 70 and that would give you . . .
180° - 70° =

Suppose a car is traveling southwest on King Avenue and turns left onto 3rd Street. What is the measure of the angle created by the car's turning? Explain your answer.</span>
This may be a little tricky on this side. These side's are coherent. As we know now that the angel on (King Ave.) was 110°, we would say the on the (3rd angel through King Ave.) that angel as well would be 110° because that is the angel on top. This would mean that they would be the same. But the thing is, we are finding what is the angel when the car is traveling southwest on King Avenue and turns left onto 3rd Street. This angel would be 70° degrees because as we do 70° + 70° + 110° + 110° = 360°.
This is how we would know that this would be that angel going into (<span>3rd Ave).
</span>My steps: 360° - 110° - 110° = 140°.
140° ÷ 2 = ∡70° ✓
Your correct answer would be

Your correct answer would equal 110°. <span>✓</span>
My steps:
360° - 75° - 75° = 210°
210° ÷ 2 = 105° ✓
