Step-by-step explanation:

You use the Distance Formula

d= √( x2 - x1 )^2 + ( y2 - y1 )^2

substitute

r= √(3-3)^2 + (4-1)^2

√0^2 + 3^2

r = √9

r = 3

Now you can use the equation for finding the circumference

2πr

2π3

≈ 6π or 18.85

Use a calculator to approximate the measures of ∠A, ∠B, and ∠C to the nearest tenth of a degree. sin A = 0.96, tan B = 0.53, cos

ivolga24 [154]

To find each of the angles we must make the following clearances:
For ∠A
sin A = 0.96
A = Asin (0.96)
A = 73.7 degrees
For ∠B
tan B = 0.53
B = Atan (0.53)
B = 27.9 degrees
For ∠C
cos C = 0.44
C = Acos (0.44)
C = 63.9 degrees
Answer:
approximate measures of ∠A, ∠B, and ∠C are:
A = 73.7 degrees
B = 27.9 degrees
C = 63.9 degrees

Do you think a mixed number is a rational number? Explain.

madreJ [45]

A mixed number is a rational number, because it is not imaginary, and it has a definite end. It is the same as its equivalent improper fraction or decimal form. This means that if the decimal form terminates, then it is rational.

A school held a special math event for parents. On the first night, 150 parents attended, which was 40% below the expected atten

Serga [27]

Answer:

10.429% exceed

Step-by-step explanation:

expected:

150x [100+40]/100=210 parents were expected on first night

210x60/100=126 parents expected on the second night

210+126=326 expected

percentage difference=

210+150=360

360/326 x 100=110,429%

110,429%-100%=10,429% exceed
