-9 ≤ x ≤ 4
it is less than or equal to -9°F, but also less than 4°F
Hope this helps
Given:
15. 
17. 
19. 
To find:
The values of the given logarithms by using the properties of logarithms.
Solution:
15. We have,

Using property of logarithms, we get
![[\because \log_aa=1]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%5Clog_aa%3D1%5D)
Therefore, the value of
is 1.
17. We have,

Using properties of logarithms, we get
![[\because \log_a\dfrac{m}{n}=-\log_a\dfrac{n}{m}]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%5Clog_a%5Cdfrac%7Bm%7D%7Bn%7D%3D-%5Clog_a%5Cdfrac%7Bn%7D%7Bm%7D%5D)
![[\because \log_aa=1]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%5Clog_aa%3D1%5D)
Therefore, the value of
is -1.
19. We have,

Using property of logarithms, we get
![[\because a^{\log_ax}=x]](https://tex.z-dn.net/?f=%5B%5Cbecause%20a%5E%7B%5Clog_ax%7D%3Dx%5D)
Therefore, the value of
is 100.
Answer:
Use the vertical motion model, h = -16t^2 + 21 , t=1 second
h = -16(1) ^2 + 21
h = 5 feet
Step-by-step explanation:
Just plug in the time with t to get your answer in height
<h3><u>G</u><u>i</u><u>v</u><u>e</u><u>n</u>:-</h3>
I = a + (n - 1)d [Given formula]
<h3><u>T</u><u>o</u><u> </u><u>F</u><u>i</u><u>n</u><u>d</u>:-</h3>
Find d when I = 10, a = 2, n = 5
<h2><u>S</u><u>o</u><u>l</u><u>u</u><u>t</u><u>i</u><u>o</u><u>n</u>:-</h2>
I = a + (n - 1)d [Given]
Putting the value of I = 10, a = 2, n = 5 we get,
10 = 2 + (5 - 1)d
10 = 2 + 4d
10 - 2 = 4d
8 = 4d
d = 
d = 2
<h3>Value of d is <u>2</u>. [Answer]</h3>
Answer: 201.06 in²
Step-by-step explanation:
Use the equation πr² to find out the area of a circle.
Since the diameter is 16 the radius is half of that, 8.
π(8)²
Work out that equation and you're done!
