Mathematics
1 answer:
EleoNora [17]3 years ago
6 0

Answer:

the measure of the smallest, positive, acute angle t formed by the terminal side of the angle t and the horizontal axis. 

90° to 180°: reference angle = 180° - angle, 180° to 270°: reference angle = angle - 180, 270° to 360°: reference angle = 360° - angle.

if your given angle is 110°, then its reference angle is 180° – 110° = 70°. When the terminal side is in the third quadrant (angles from 180° to 270°) your reference angle is your given angle minus 180°. So, if your given angle is 214°, then its reference angle is 214° – 180° = 34°.

A credit card company uses your average daily balance to compute your finance charge. You charge $100 on May 2 and $200 on May 2
liraira [26]

Answer:

<h2>$5.56</h2>

Step-by-step explanation:

On may 2, charge = $100

On may 20, charge = $200

To get the average daily balance, we will use the concept of calculating slope;

let d be day of the month and c be the amount charged

when d1 = 2, c1 = 100

when d2 = 20, c2 = 200

average daily balance = c2-c1/d2-d1

average daily balance = 200-100/20-2

average daily balance = 100/18

average daily balance ≈ 5.56

Hence your average daily balance is approximately $5.56

The first three terms of a sequence are given. Round to the nearest thousandth (if necessary).
zalisa [80]

Answer: 272

Step-by-step explanation:

Let a1=11

a2=20

a3=29

Formula for sequence=

an=a1+(n-1)d

an = nth term

a1= first term

n= nth position

d= common difference

We are looking for the 30th term,so our n=30

d= a2-a1

d= 20-11

d= 9

Using the formula

an= a1+(n-1)d

a30= 11+(30-1)9

a30= 11+(29)9

a30= 11+(29×9)

a30= 11+261

a30= 272

Therefore, the 30th term is 272

Answer: 11.4

Step-by-step explanation:

area of rect. = 24

area of circle (half circle+half circle = full circle) = pi*r^2 = pi*(2*2) = pi*4 = about 12.57

2 = radius since 4 = diameter

24-12.57 = 11.43

round = 11.4
