Answer: A =350 (1.05)^t

Step-by-step explanation:

Hi, to answer this question we have to apply an exponential growth function:

A = P (1 + r) t  

Where:

p = original population

r = growing rate (decimal form; 5/100=0.05)

t= years

A = population after t years

Replacing with the values given:

A = 350 (1+0.05)^t

A =350 (1.05)^t

Answer:

Angle CED must also measure 60°. 

Because angle m is shown to be congruent to angles ABC and CDE, this means that angle m has a measure of 60 degrees.

There can only be 180 degrees in a triangle, so the measure of angle ACB must be 180-60-60, which equals 60 degrees.

Using the Vertical Angles Theorem, the measure of angle ACB is the same as the measure of angle CED.

Therefore, angle CED measures 60°.

Step-by-step explanation:

m, because Triangle ABC is similar to triangle EDC

m over 2, because Triangle ABC is congruent to triangle DCE

m + 60 degrees, because Triangle ABC is similar to triangle DCE

120 degrees − m, because Triangle ABC is congruent to triangle DCE

A bacteria cell splits into two cells every hour. Write and evaluate an exponential expression to find how many cells there will
ryzh [129]
Easy

equation is
f(x)=2ˣ

where x=number of hours elapsed

after 6 hours
f(6)=2⁶=64 bacteria


to solve for 1024

1024=2ˣ
take ln of both sides
ln(1024)=ln(2ˣ)
ln(1024)=x(ln(2))
divide both sides by ln(2)
ln(1024)/ln(2)=x
using calculator
10=x

or you could recognize that
1024=2¹⁰
or keep divising 1024 by 2


10 hours for 1024 bacteria

What value of n solves the equation <br><br> 3n=1/81<br><br> N=___
Radda [10]

3n = 1/81; divide both sides by 3 to isolate n:


3n/3 = 1/81 divided by 3. Remember that when you divide, you use the reciprocal and multiply instead!!


n = 1/81(1/3) = 1/243. Now plug 1/243 back in for n, and 3/243 is equivalent to 1/81

Solve for x and then find the measure of
harkovskaia [24]

Answer:

x = 11

∠B = 80°

Step-by-step explanation:

∠A =∠B because they are corresponding angles

8x - 8 = 5x + 25

3x = 33

divide both sides of the equation by 3:

x = 11

∠B = 5(11) + 25 = 80°
