Answer: D) \dfrac{3\pi}{2} radians

Step-by-step explanation:

In geometry, the radius of a unit circle = 1 unit.

Given: The arc length of a sector in the unit circle =\dfrac{3\pi}{2}

We know that the formula to calculate length of arc having central angle x and radius r is given by  :-

l=rx

Substitute r= 1  and  l=\dfrac{3\pi}{2} in the above formula , we get

\dfrac{3\pi}{2}=(1)x\\\\\Rightarrow\ x=\dfrac{3\pi}{2}

Hence, the  measure of the angle of the sector =\dfrac{3\pi}{2} radians

10) What is the area of the figure below? Round your answer to the nearest tenth (1 place
snow_lady [41]

Answer:

Step-by-step explanation:

Divide the figure into a rectangle and a triangle.

area of rectangle = 5×10 = 50 square units

area of triangle = 0.5×5×10 = 25 square units

total area = 50+25 = 75 square units

Answer:

Each bag will get 5 candy canes and 3 cookies.

Step-by-step explanation:

Find the divisors of both numbers

75 = 1,75 : 3,25 : 5,15 : 15,5 : 25,3 : 75,1

45 = 1,45 : 3,15 : 5,9 : 9,5 : 15,3 : 45,1

Since the largest common divisor is 15, we want to use 15.

Each bag will get 5 candy canes and 3 cookies.

Write an exponential function y = abx for a graph that includes (2, 24) and (3, 48).
labwork [276]
I think you mean y=ab^x.
First, plug in the values of x=2 and y=24 for the first equation, and x=3 and y=48 for the second one:

24 = ab^2
48 = ab^3

divide equation 2 by equation 1:
2 = b^1

or, more simply:
2 = b

now plug b into one of the equations to get "a":

24 = a*2^2
24 = a*4
6 = a

So, the answer is y = 6(2)^x
(I think you need to specify the power of x in your answers)
