Answer:
29°
Step-by-step explanation:
cos x = 84/98
x = cos-1(84/98)
x = 28.9
Answer:
The value of x is about 2.206.
Step-by-step explanation:
Consider the given equation is
We need to find the value of x.
Using the properties of logarithm we get
![[\because \ln a^b=b\ln a]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%5Cln%20a%5Eb%3Db%5Cln%20a%5D)
![[\because \ln (ab)=\ln a+\ln b]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%5Cln%20%28ab%29%3D%5Cln%20a%2B%5Cln%20b%5D)
![[\because \ln 1=0]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%5Cln%201%3D0%5D)
On comparing both sides we get
Using graphing calculator, the real solution of the above equation is
Therefore, the value of x is about 2.206.
A scuba diver was exploring a
reef 32.12 m below sea level. The diver ascended to the surface at a rate of
8.8 m/min.
a. using the formula d = rt,
so 32.12 m = 8.8m/min (t)
b. it is reasonable to write
the distance as positive because the diver is accending/ going up the surface
<span>c. t = 32.12/ 8.8 = 3.65 min</span>
35x – 13 x = x – 1
⇒ 22 x = x - 1
⇒ 22x - x = -1
⇒ 21x = -1
⇒ x = -1/21
Thus,the value of x is -1/21
