The Answer is A
5x=85 (to find the x get the x alone so divide 5 from 5x and also do the same on the other side with 85)
112=4y+4 (minus 4 from 4y+4 and minus 4 on the other side as well with the 112, 112-4=108
108=4y (get the y by itself so divide 4 from 4y and divide 4 from 108 as well, 108/4= 27)
The measure is 61 degrees
Using an exponential function, it is found that it's annual growth rate is of 4%.
<h3>What is an exponential function?</h3>
An increasing exponential function is modeled by:
In which:
- A(0) is the initial value.
- r is the growth rate, as a decimal.
In this problem, the card appreciates exponentially in value by 50% over 10 years, hence:
A(10) = 1.5A(0).
Thus:
![\sqrt[10]{(1 + r)^{10}} = \sqrt[10]{1.5}](https://tex.z-dn.net/?f=%5Csqrt%5B10%5D%7B%281%20%2B%20r%29%5E%7B10%7D%7D%20%3D%20%5Csqrt%5B10%5D%7B1.5%7D)
1 + r = 1.04.
r = 0.04.
0.04 x 100% = 4%.
It's annual growth rate is of 4%.

Answer:
Step-by-step explanation:
g(m) = 0
2-4m=0
2=4m
2/4=m
1/2=m------(1
p(1/2)= -3(1/2) - { 2(1/2) + (5- 1/2) } +7
= -3/2 - { 1 + 9/2} +7
= -3/2 - ( 11/2) +7
=-14/2 +7
= -14 + 14 /2
= 0/2
= 0...
since p(m)= 0,
we can say that g(m) is a factor of p(m)
hence, it has been simplified correctly...
Fiber optic type of cable is uses a two-number designator consisting of core and cladding measurements.
What does fiber optics serve?
- Fiber optics are used for long-distance and high-performance data networking.
- It is often used in other telecommunications services as well, including internet, television, and telephones.
What methods are used to deploy fiber optics?
- Installing fiber optic cable indoors or outdoors can be done using a variety of installation methods.
- Outdoor cable can be buried or placed in between poles. It may also be blasted or dragged into an innerduct or conduit.
Can fiber optics compete with the internet?
- When compared to normal cable internet and DSL, fiber optic internet is about 20 and 80 times faster.
- Fiber is the best choice for the majority of internet users because it only costs $10 to $20 more each month.
