Answer:
Step-by-step explanation:
vector OA=a
vector OB=b
vector OX= λ vector OA=λa
vector OY=μ vector OB=μb
a.
1.vector BX=(vector OX-vector OB)=λa-b
ii. vector AY=(vector OY-vector OA)=μb-a
b.
5 vector BP=2 vector BX
5(vector OP-vector OB)=2 (vector OX-vector OB)
5(vector OP-b)=2(λa-b)
5 vector OP-5b=2λa-2b
5 vector OP=2λa-2b+5b
vector OP=1/5(2λa+3b)
ii
complete it.
Answer:
Klog earned $135.45 altogether.
Step-by-step explanation:
<u>Hours</u>
<em>Monday - Friday : 5 days / 3.5 hours</em>
<em>Saturday : 1 day / 4 hours</em>
3.5 · 5 + 4
= 17.5 + 4
= 21.5
<u>Money</u>
<em>$6.30 per hours / 21.5 hours</em>
6.30 · 21.5
= $135.45
Answer: Explanation below.
Step-by-step explanation:
First of all you need to know how to convert a logarithm into an exponential expression. The property is:
This is the same as: 
Example 1:
We are trying to find what to raise 9 to, in order to get a result of 9.
When you have same bases, you equal exponents.
Therefore; 
Example 2:
In this case, we have to make sure both sides have the same base. 32 can have a base of 2 if expressed as: 
which is 2*2*2*2*2
Rewriting this example we have;
Since we have the same base, we equal exponents.
Therefore; 
Example 3:
729 can have a base of 3 if expressed as: 
Answer:
tan38 = 0.31
cos47 = -0.99
sin77 = 0.99
