Answer:
D) 0
There is 1 real solution.
Step-by-step explanation:
Hi there!
This is written in standard form:
This means:
a=9
b=30
c=25
The discriminant states:
If D>0, there are 2 real solutions.
If D=0, there is 1 real solution.
If D<0, there are 2 complex solutions.
Plug in the values:
Therefore, there is 1 real solution.
I hope this helps!
First I'll simplify the first one by distributing
11m + 10p
And the second
10p + 11m
Yep they're equal
Answer:
1.) Circumference of circle A = 131.95 metre
2.) Circumference of circle B = 175.93 metre
3.) Yes. Radius is proportional to the circumference.
Step-by-step explanation: Given that Circle A has a radius of 21 meters and Circle B has a radius of 28 meters
Circumference of a circle = 2πr
For circle A
Radius r = 21
Circumference = 2 × 3.143 × 21
Circumference = 131.95 metre
For circle B
Circumference = 2 × 3.143 × 28
Circumference = 175.93 metre
Is the relationship between the radius of a circle and the distance around the circle the same for all circles? YES
Because the radius of the circle is proportional to the distance around them ( circumference ) for all the circle. That is, the larger the radius, the larger the circumference
Answer:
3/5
Step-by-step explanation:
15 and 25 go into 5 so you divide 15 by 5 that's 3 and 25 by 5 which is 5
Ummm ....... I think x=80
