From the diagram above you can see that points A and B have coordinates (8,0) and (-4,6), respectively.
The equation of the line passing through the pointa A and B is:

Answer:
C=20
Step-by-step explanation:
Pythagorean theorem is a^2 + b^2=c^2. So, a=16, and b=12. 16 squared is 256. 12 squared is 144. 256+144=400. 400=c^2. So, the square root of 400=c. and that is 20.
Answer:
56.7%
Step-by-step explanation:
First determine the number of girls
30-13 = 17
The fraction of girls is 17/30
Changing this to a decimal is
.566666666
Changing to a percent
56.666666%
To one decimal place
56.7%
Step-by-step explanation:
when we simplify the original expression, we can combine the y parts and the x parts - remember multiplying with exponents means adding the exponents.
so,
y^-8 × y^3 = y^(-8 + 3) = y^-5
x^0 × x^-2 = x^(0 - 2) = x^-2
therefore, the main expression is actually
y^-5 × x^-2
now also remember, a negative exponent means 1/...
so, this is
1/(y⁵) × 1/(x²) = 1/(y⁵x²)
now, let's have a look at the answer options and compare with our results above :
the first one is wrong.
the second one is correct.
the third one is correct.
the fourth, fifth and sixth ones are wrong.
