Answer:

m∠XYZ=106°, m∠XWY = 53°

Step-by-step explanation:

XYZ is a central angle, its arc is XY = 106°. so m∠XYZ = mXY=106°

XWY is an inscribed angle, its arc XY = 106°, so m∠XWY =1/2 mXY=1/2*106=

= 53°

Find the greatest common factor (GCF) for 10x2 and 15xy2.

Answers

This answer uses NMF, which if needed you can read the syntax on my profile:

If we do a partial prime factorisation, we get these, where a and b are the sets containing the prime factors:
a = 10•2 = 20 = {2}^{2}•5
b = 15x{y}^{2} = 3•5•x•{y}^{2}

a∩b = {5}
multiply the elements of a∩b = 5

Therefore the GCF of 10•2 and 15•x•{y}^{2} is 5

Simplify this expression (5)^ -5 (5)^ 7 please explain how you got the answer A.1/25
B.25
C.10
D. 5^ -35

Answers

Answer:

( {5}^( - 5) ) * ( {5}^(7) ) \n  \n  \frac{ {5}^(7) }{ {5}^(5) }  =  {5}^(7 - 5)  =  {5}^(2)

the answer is b. 25

Answer:

= 4

Step-by-step explanation:

2a^2-4b

=2(2)^2-4(1)

=2×4-4

= 8-4

=4

choose the equation below that represents the line passing through the point (1, −4) with a slope of 1/2. a.) y − 4 = 1/2(x − 1) b.) y 4 = 2(x − 1) c.) y 4 = 1/2(x − 1) d.) y − 4 = 2(x 1)

Answers

Point (1, -4)
Slope=1/2
y=mx+c
y=1/2x +c
-4=1/2(1)+c
-4=1/2+c
c=-4-1/2
c=-4 1/2
