Answer:
2 in 52.3
Step-by-step explanation:
the two in 52.3 represents 2
Answer:
C. -1/2
Step-by-step explanation:
well the formula for slope is m=(y2-y1/x2-x1). y2 = -5 y1= 3 x2 = 2 x1 = -14. put that all together to get -5-3/2-(-14). well -5 - 3 = -8. the second one is like a multiplication problem so a negative minus a negative is a positive. which give u 2 + 14 = 16. so you get the fraction -8/16 both are divisible by 8 so divide the equation by 8 and you get -1/2.

Question 1
----------------------------------------------------------------
a² + b² = c²
9² + 14² = c²
c² = 81 + 196
c² = 277
c= √277
c = 17cm (Rounded to the nearest whole number)
----------------------------------------------------------------
Ans: The Slanted height is 17cm (Answer C)
----------------------------------------------------------------
----------------------------------------------------------------
Question 2
----------------------------------------------------------------
Lateral area of the cone = πrl
1080π = π(60)l
l = 1080π ÷60π
l = 18.0cm
----------------------------------------------------------------
Ans: The slanted height is 18.0cm (Answer D)

Answer:
11r²-4r-3
Step-by-step explanation:
soo,, now firstly change the signs of 2nd expression
so,
9r²+5r-11+2r²-9r+8
now
we will combine the same terms like , see next step
9r²+2r²+5r-9r-11+8
11r²-4r-3
