Answer:
The new price is 42.50
Step-by-step explanation:
First find the discount
50 *15%
50 *.15
7.5
Subtract this from the original price
50-7.5
42.50
The new price is 42.50
Answer:
10
Step-by-step explanation:
Formula you are going to use: 
you will use k to help you resolve for y :)
(multiply by 2 to cancel the fraction)- 200 = k
Now you will replace k with 200 :)
- <u>y = 10</u>

Answer:
k = 2
Step-by-step explanation:
Integral is [k×tan(x/k]
If its equal to k,
k×tan(x/k) = I
tan(x/k) = 1
x = pi/2 upper limit
x = 0 lower limit
tan(pi/2k) - tan(0) = 1
pi/2k = pi/4
So, k = 2
We know that
<span>sec (theta)=1/cos (theta)
</span><span>cot (theta) = -2
cot (theta)=cos (theta)/sin (theta)
</span>cos (theta)/sin (theta)=-2----> squaring-----> cos² (theta)/sin² (theta)=4
<span>remember that
sin</span>²(theta)+cos²(theta)=1
sin² (theta)=1-cos² (theta)
substitute
cos² (theta)/[1-cos² (theta)]=4
cos² (theta)=4*[1-cos² (theta)]-----> cos² (theta)+4 cos² (theta)=4
5*cos² (theta)=4-----> cos² (theta)=4/5----> cos (theta)=2/√5
cos (theta)=(2√5)/5-----> is positive (IV quadrant)
sec (theta)=1/cos (theta)----> √5/2
the answer is
sec (theta)=√5/2
