Answer:
Y=x+1...written on the line between c and b
Step-by-step explanation:
CB is perpendicular to EF.
The slope is 1, the y intercept is 1
Therefore. Y =mx+B is y=1x+1
Answer:
Radius: 7.75
Volume: 1949.82
Step-by-step explanation:
The radius is half the diameter, so 15.5/2 is 7.75
The formula for a sphere is V=4/3 (πr^3). All that needs to be plugged in is the radius. You should be able to use a calculator for this problem, so the rounded answer is 1949.82.
Answer: V = 4.99482 cm^3
Explain: I used the formula V = m/p and found the density (p) of gold using the internet.
Answer:
6. 8b²-5b-4
7. -3x²+9x-4
8. 3
9. 6a+15
Step-by-step explanation:
you will subtract/add the numbers with the same variables and exponent.
ex. (number 6) 7b²+ b²= 8b²
5b= 5b 8b²+5b-4
1-5= -4
(plus 5b because it didnt come out to a negative) if you have any questions, say in the comments and ill try my best to help
