Answer:



Step-by-step explanation:
I will solve this question with the attached triangle
From the attachment, we have:



Required
Solve the triangle
First, we calculate
using sine law:

This gives:


Cross multiply


Divide both sides by 29

Take arcsin of both sides

Next, calculate
using:
--- angles in a triangle

Collect like terms


Next, calculate BC using sine laws

This gives:


Make BC the subject


4a.4²x +3=1
Slotuion:
4²x + 3=1 : <em>x</em>= -⅛ (Decimal:<em>x</em>= -0.125)
Steps
4² x +3=1
4²=16
16x + 3=1
Subract 3 from borh sides
16x +3-3=1-3
Simplify
16x=-2
Divides both sides by 16
![\frac{16 \times }{16} = [tex] \frac{ - 2}{16}](https://tex.z-dn.net/?f=%20%5Cfrac%7B16%20%5Ctimes%20%7D%7B16%7D%20%3D%20%3C%2Fp%3E%3Cp%3E%5Btex%5D%20%5Cfrac%7B%20-%202%7D%7B16%7D%20)

Simplify

<em>x</em> = -⅛
therefore the answer is <em>x</em><em>=</em><em> </em><em>-</em><em>⅛</em>
4b.ex-1 -5 =5
x~=3.30258
explanation:
e^(x-1)-5=5
e^(x-1)=10
x-1=ln 10
x-1~=2.30258
x~=3.30258

Answer:
x= -4.284 and y= 1.432
Step-by-step explanation:
Solution: We are given:

Let
be the weight (oz) of laptop
We have to find 
To find the this probability, we need to find the z score value.
The z score is given below:



Now, we have to find 
Using the standard normal table, we have:

0.9236 or 92.36% of laptops are overweight
Answer:
1. 2/4 = 1/2
2. 9/24= 3/8
3. 56/64= 7/8
