To 3 decimal places.
128.59943
Count three places to the right after the decimal point. The third digit is 9, and the fourth is 4. Since the 4th is not up to 5, we leave the 9 that way and so we can not round up the 9 to 10.
So it becomes = 128.599
Thanks.
Answer:
Step-by-step explanation:
(x-1)(x+2)/x^2(x-1)+2(x-1)
(x-1)(x+2)/(x-1)(x^2+2)
(x+2)/(x^2+2)
Trigonometric values (sin, cos, tan etc.), represents the ratio between two sides.
In this case the triangle is dilated, which means the size will change but the shape will stay proportional.
Because the sides grew proportional their ratio stays the same; so, the tan in the second triangle is 22/5 too.
Moreover, because the sides grew/shrunk proportional, the angles stay the same.
Because same angles have the same trigonometric values, tan(x) in second triangle becomes 22/5.
Answer:
4/15
Step-by-step explanation:
2/3 play sports
2/5 play football
Of the 2/3 that play sports, 2/5 of them play football
2/3(2/5) = 4/15
The frog's jump represent a geometric series.
The sum of finite geometric series can be solved using the equation:
Sn = ao ( (1-r^n)/(1-r) )
Plugging in the values,
S8 = 1 ( (1-2^8)/(1-2) )
S8 = 255
Therefore, after 8 hops, the frog will have traveled 255 inches
