Answer:
z-4
Step-by-step explanation:
z(5z²-80) ÷ 5z(z+4) = z-4
Step-by-step explanation:
Given: z(5z²-80) ÷ 5z(z+4)
Calculation:
First we factor numerator z(5z²-80)
Take out 5 from 5z²-80 and we get 5z(z²-16)
Now we factor 16 = 4²
5z(z²-4²)
Using formula, (a²- b²)=(a+b)(a-b)
5z(z²- 4²)⇒5z(z+4)(z-4)
Simplified fraction
5z(z+4)(z-4) ÷ 5z(z+4)
Cancel like factor from numerator and denominator
⇒ z-4
Thus, z(5z²-80) ÷ 5z(z+4) = z-4
Using opposite outside angle on a circle is the inside angle times 2.
A is opposite the inside angle of 45, so a = 45 x 2 = 90 degrees.
Answer:
option C is correct,the null hypothesis equals 1.8
Answer:
Step-by-step explanation:
4. 2x+8+3x+5=123 (ext∠)
5x=110
x=22
5. 25+2x+3=3x-17 (ext∠)
x= 45
6. 5x+2+6x+4=12x-4 (ext∠)
x= 10
The y-intercept should be the height it started at before it started to descend.
So, 300 units.
