Let the number of rides you went on be x.
4 + 0.8x= 12 + 0.3x
0.5x = 8
x = 16
You went on 16 rides.
x + 2
x + 1 |----------------------------
x^2 + 3x + 5
-(x^2 + x)
=============
2x + 5
-(2x + 2)
=========
3
(x^2+3x+5)/(x+1) = x+2 + 3/(x+1)
The discriminant needs to be greater than 0.
\(\Delta = b^2- 4ac = 225 - 32c > 0\)
\(c < \frac{225}{32}\)
225/32 is equal to 7.03125, so c can be any integer from 1 to 7. The sum is 28.
\(-3(1+4i) + i(-2-i) = (-3-12i) + (-2i +1)= \boxed{-2 - 14i}\)
Here are the sums of the digits of the numbers you listed in order:
1, 8, 2, 5, 6, 10, 6, 12, 6, 7, 8, 7, 20, 13, 7, 11, 12, 9, 12, 15, 16, 13, 13, 16, 17
Count the ones that are odd.
Diameter= 0.4 cm ==> \(V = \frac{4}{3}\pi r^3 = \frac{4}{3} \pi \cdot 2^3 = \frac{32}{3} \pi\), or about 33.51 cm^3.
Each lead ball has a mass of (33.51)(11.3) = 378.663 g.
So, 5000 balls have a mass of 1,893,315 g or 1,893 kg.
This is a geometric sequence with starting term 3/16 and common ratio 4.
The third term is c(3) = c(1) * 4^2 = 3.
You can simply plug this into your calculator.
\(\sec(19^{\circ}) = \boxed{1.057}\)
The answer is D.
1. 196 = 14^2 = 2^2 * 7^2
2. GCD(7a^3, 54a^2) = a^2
3. GCD(108, 162) = 54
Primero: $15.10
