Mathematics
1 answer:
rusak2 [61]3 years ago
4 0

Step-by-step explanation:

42+5x+7x+6=180 (sum of angles in straight line is 180)

  • 48+12x=180
  • 12x=180-48
  • 12x=132
  • x=132/12
  • x=11

now m <CBE =7x+6=7×11+6=77+6=83

Which is the graph of the sequence defined by the function f(x + 1) = 2/3 f(x) if the initial value of the sequence is 108?
san4es73 [151]

Answer:

The fourth graph.

Step-by-step explanation:

We have f(x + 1)  so the x values will be increased by 1.

first value = 108 (when x  = 1)

next value = 108 * 2/3 = 72 (when x = 2)

next = 72 * 2/ 3= 48 (when x = 3)

next = 48 * 2/3 = 32 (when x = 4)

The space shuttle discovery was retired in spring thousand and 12 discovery was first launched in 1984 and flu over 149,000,000
Rina8888 [55]

Answer:

it would be about 5984 times around the earth

Step-by-step explanation:

first of all 149,000,000 miles is active lifetime

Using those measurements, the equatorial circumference of Earth is about   24,901 miles

so therefore if you divide 149,000,000 by 24,901 you would get the answer of 5983.69543392 so if you round all the numbers to the nearest whole number you would get 5984

hope tis helps out with your question

Hello need help please with Divide rational and simplify
aliina [53]
Dividing fractions is the same as multiplying by its reciprocal so you can change the equation to this
\frac{ - 14 + 7x}{4}  \times  \frac{4}{4 - 2x}
And you can simplify by eliminating the fours and multiplying straight across
\frac{ - 14 + 7x}{4 - 2x}
You can pull out - 7 from the top and 2 from the bottom so you have this
\frac{ - 7(2  -  x)}{2(2 - x)}
And then you can cancel out to (2-x) to get an answer of
\frac{ - 7}{2}

A research student is working with a culture of bacteria that doubles in size every
ser-zykov [4K]

Answer:

2^{24}*1000 bacteria

Step-by-step explanation:

The generic form of an exponential function is: f(n)=ar^n , where a is the initial amount, r is the rate, and n is the time.

In this case, the initial amount is 1000, so a = 1000. Also, the rate is 2 because the culture doubles in size every 5 minutes. However, our n is not just n; it's actually n/5 because the rate is doubling per 5 minutes, not per 1 minute. If it was per 1 minute, then the time would simply be n. Unfortunately, that's not the case here, so the exponent of r should be n/5, where n is the number of minutes that have passed.

Now, we have: f(n)=1000(2)^{n/5}

Since n is the number of minutes, we need to convert 2 hours to minutes:

2 hours * 60 min/hour = 120 minutes.

f(120)=1000(2)^{120/5}=1000(2)^{24}=2^{24}*1000f(120)=1000(2)^{120/5}=1000(2)^{24}=2^{24}*1000

Thus, the answer is 2^{24}*1000 bacteria.

Hope this helps!
