Answer:A) 4 roots
b)(-2,0)(-1,0)(1,0)(3,0)
c)(0,-6)
d) down
Step-by-step explanation:
a) there are 4 roots because the max power = the number of turns in a graph
b) plug in 0 for y and solve
c)plug in 0 for x
d)the largest exponent x^4 is negative and since it is even you start and end the opposite way and since it is negative it starts up and goes down
Please I need help with 2 problems and I need help Explaining how I got the answer correct for both of the problems and it’s very hard and I’m struggling with it and if you need to see the picture big then click on it and it will be big
Yes you are correct
It will be a circle with a center of (3, -4) and a radius of 12.
Answer:
1500 Time the multiple of model scale is the actual length of the ramp.
Step-by-step explanation:
Given:
Actual length of ramp is 500ft
Modelling scale is 1/125.
To Find:
how many times as long as the actual on ramp is the model.
Solution:
Actual length is 500 ft
When Civil engineer is modelling the ramp on model then it is about 1/125 of the actual length present at that site.
So
=500*1/125
=4 inches
So on model scale engineer took inches as a unit for scale.
Actual length is 500 ft and model length is 4 inches
So 1 ft corresponds to 12 inches hence 500*12=6000 inches
6000 inches corresponds to 4 inches on model scale
i.e it is about 1500 time multiple of the model scale.
