Answer:
A. (x-5)(x-5)
Step-by-step explanation:
We need to factor x^2-10x+25 into the form (x+y)(x+y) where 2y=-10 and y^2=25
2y=-10
y=-5
So this becomes (x-5)(x-5)
Hope this helped!
They can ride their bike 12 miles because in 6 minutes they ride 0.8 miles so in 1.5 hours they ride 12 miles. 0.8 * 10 = 8 miles 1 hour so 0.8 * 5 = 4 miles 0.5 hours 8 miles + 4 miles =12 miles 1 hour + 0.5 hours = 1.5 hours
Answer:
The constant factor between consecutive terms of a geometric sequence is called the common ratio.
Example:
To find the common ratio , find the ratio between a term and the term preceding it. r=42=2. 2 is the common ratio.
Answer:
Rise: 200.25
Descent 300.2
Minutes
Step-by-step explanation:
A) We are using the Pythagorean theorem for the climb and descent. (a^2 + b^2 = c^2)
For climb a = 200, b = 10 c = ?
200^2 + 10^2 = c^2 = 40000 + 100 = c^2 = 40100 = c^2
c = about 200.25
For the descent: a = 300, b = 10
300²+10² = c²
90000 + 100 = c²
90100 = c²
c = about 300.2
B) If a plane is going 600 km/h and it goes about 10 km that means the plane is only going for 10/600 of an hour.
10/600 is 1/60, so only a couple minutes difference.
Answer:
0 and 0
Step-by-step explanation:
The only number that can be applied to the expression without changing the sum is 0, for example 5 + 10 = 15, adding 2 0's will be 0 + 5 + 10 + 0 = 15 :D
