Find the measure of the angle shown by the arrow(in radians)

soldi70 [24.7K]

Answer:

-7π/3 or -420 degrees

Step-by-step explanation:

So we know that the arrow has made one full rotation and that it is moving in a clockwise direction. So already we have -2π degrees.

The arrow stops at π/6 before the next π/2 rotation. Therefore we find the difference between the two.

π/2 - π/6

3π/6 - π/6 = 2π/6

π/3

Since this is still clockwise, we make this negative. So the measure of the angle shown by the arrow is -2π - π/3

Write an equation of a circle whose center is (-5,4) and whose diameter is 12

musickatia [10]

Answer:

(x + 5)² + (y - 4)² = 36

Step-by-step explanation:

The equation of a circle in standard form id

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

Here (h, k) = (- 5, 4) and r = 12 ÷ 2 = 6 , thus

(x - (- 5))² + (y - 4)² = 6², that is

(x + 5)² + (y - 4)² = 36

a local specialty delivery service charges a fee of $7 for each delivery plus. 45 cents for each mile over 10 miles. what variab

julia-pushkina [17]

Answer: Independent variable = number of miles he drive over 10 miles

Dependent variable = Total fee (in dollars)

Step-by-step explanation:

Given : Charge for each delivery = $7

Addition charge for each mile over 10 miles = 45 cents = $0.45

[ 1 cent = $ 0.01 ]

Since the fee vary by the number of miles he drive over 10 miles.

So , Independent variable = number of miles he drive over 10 miles

Dependent variable = Total fee (in dollars)

Let x= number of miles he drive over 10 miles

y= Total fee (in dollars)

Such that , $y= 7+0.45x$ [Total fee= Fixed charge + Additional charge ]

So , the appropriate variables are:

Independent variable = number of miles he drive over 10 miles

Dependent variable = Total fee (in dollars)
