The radius of the circle that surround the star is 5 cm. Which measurement is closest to the circumference of the circle?
Answers
Answer:
31.4cm
Step-by-step explanation:
According to the scenario, computation of the given data are s follows,
Radius (r) = 5 cm
So, we can calculate the circumference of circle by using following formula,
Circumference of circle = 2 π r
By putting the value in the formula, we get
Circumference of circle = 2 × π × 5
= 10 ×π
= 10 × 3.14
= 31.4 cm
Hence, circumference of circle is 31.4cm.

The -1/2x is the slope or the rise/rub
The -3 is the y-intercept
So start by placing the y-intercept (0,-3), then from there place the slope (-1/2), since the slope is negative instead of going up one and two to the left you are going to go down one and two to the right, then place a point and repeat. After repeating 2-3 times you should be able to connect the points in order to make a line. If you have any questions let me know!

Question 15 of 40
For which sample size (n) and sample proportion () can a normal curve be
used to approximate the sampling distribution?
O A. n = 28; = 0.3
O B. n = 28; p = 0.9
O c. n = 32; p = 0.4
O D. n = 32; p = 0.2
Answers
Answer:
Option C: n = 32; p^ = 0.4
Step-by-step explanation:
The normal curve can be used in this case if; np ≥ 10 or n(1 - p) ≥ 10
A) For n = 28 and p = 0.3;
np = 28 × 0.3 = 8.4 < 10
Thus, it can't be used.
B) For n = 28 and p = 0.9;
np = 28 × 0.9 = 25.2 > 10 Ok
n(1 - p) = 28(1 - 0.9) = 2.8 Not Ok
Thus, it can't be used
C) For n = 32 and p = 0.4
np = 32 × 0.4 = 12.8 > 10 Ok
n(1 - p) = 32(1 - 0.4) = 19.2 > 10 Ok
Thus, it can be used
D) For n = 32 and p = 0.2
np = 32 × 0.2 = 6.4 < 10 Not Ok
Thus it can't be used.

Write an exponential function in the form y=ab^xy=ab x that goes through points (0,8) and (2,288)
Answers
Answer:
y = 8•6^x
Step-by-step explanation:
Here, we want to write an exponential equation
To fully write this, we need the values of a and b
From the first coordinates given;
8 = a•b^0
a = 8 since b^0 = 1
Furthermore;
288 = 8•b*2
b^2 = 36
b = √36
b = 6
So we have ;
y = 8•6^x

A horse runs in a field the speed time graph represents the first 12 seconds of the run after how many seconds had the horse run a distance of 75 metres
Answers
Answer:
9.5 seconds
Step-by-step explanation:
0-4 seconds => 20 meters
4-9.5 seconds => 55 meters
total = 75 meters
A horse run a distance of 75 metres in 9.5 seconds.
What is Speed?
The speed formula can be defined as the rate at which an object covers some distance. Speed can be measured as the distance traveled by a body in a given period of time.
Here, From the graph,
when, t = 4 sec.
distance = 4 X 10 X 1/2
= 20 meters
Now, 75 - 20 = 55 meters
So, 55/10 = 5.5 seconds
Total time = 5.5 + 4
= 9.5 sec.
A horse run a distance of 75 metres in 9.5 seconds.
Thus, A horse run a distance of 75 metres in 9.5 seconds.

Shinji started with angle ∠ABC and constructed ray BE
Answers
Answer:
A and C
Step-by-step explanation:
Statements B) BA ≅ BC and C) AE ≅ DE guarantee that ray BE bisects angle ABC.
Statement B states that BA is congruent to BC. This means that side AB is the same length as side BC. Since the bisector of an angle divides the opposite side into two segments with equal lengths, this guarantees that ray BE bisects angle ABC.
Statement C states that AE is congruent to DE. This means that the segments AE and DE have the same length. Since the bisector of an angle divides the opposite side into two segments with equal lengths, this guarantees that ray BE bisects angle ABC.
The other statements are not sufficient to guarantee that ray BE bisects angle ABC. For example, if BA is congruent to BD, this does not mean that the segments AE and DE have the same length. Similarly, if BD is congruent to DE, this does not mean that side AB is the same length as side BC.
Therefore, the correct answers are B and C.
