how to round 10.71428571 by the nearest ten.
Answers
Answer:
Well if it is rounding to the nearest 10 it is 10
but if you meant round to the nearest 10th then it is 10.7
Step-by-step explanation:
For 10 you look at the ones place if it is 0-4 round down if it is 5-9 round up so for this number round down which is 10
FOr 10.7 look at the hundredths place if it is 0-4 round down if it is 5-9 round up so for this number round down which is 10.7

Twinkle toes tony kick the football and it landed 100 feet from where he kicked it also reach a maximum height of 125 feet write an equation that models the path of the ball while it was in the air
Answers
Answer:
The equation that models the path of the ball is y = 5·x - 0.05·x²
Step-by-step explanation:
The given information are;
The distance the football landed from where it was kicked = 100 feet
The maximum height the football reached = 125 feet
The equation that models the path of the ball is that of the equation of parabola in vertex form, given as follows;
y = a·(x - h)² + k
Where;
(h, k) = The coordinate of the vertex (which is the coordinates of the highest point reached by the ball)
Therefore, taking the x-coordinate of the highest point reached by the ball as midpoint of the horizontal distance moved by the ball, we have;
The x-coordinate of the midpoint of the horizontal distance moved by the ball = (50, 0)
We have;
The coordinate of the highest point reached by the ball = (50, 125)
Therefore;
(h, k) = (50, 125)
Substituting the above values in the equation of the parabola gives;
y = a·(x - 50)² + 125
At x = 100, y = 0, which gives;
0 = a·(100 - 50)² + 125 = a·2500 + 125
0 = a·2500 + 125
a = -125/2500 = -0.05
Therefore, we have;
y = a·(x - h)² + k = y = -0.05 × (x - 50)² + 125 = -0.05·x² + 5·x - 125 + 125
y = -0.05·x² + 5·x - 125 + 125 = -0.05·x² + 5·x
y = -0.05·x² + 5·x
The equation that models the path of the ball is y = -0.05·x² + 5·x.

A canoe rental service charges a $20 transportation fee and $30 dollars an hour to rent a canoe. Write an equation representing the cost, y, of renting a canoe for x hours. What is the cost of renting the canoe for 6 hours?
Answers
Answer:
use slope intercept form to write the equation y=mx+b m (slope of the line) will be the hourly fee, and b (y-intercept) will be the one-time transportation fee.
y=30x+20
to find the cost of renting a canoe for 6 hours, plug 6 into the equation replacing x
y=(30×6)+20
y=180+20=$200
Sorry, I can't graph the line, but I would number the x-axis of the coordinate plane (graph) by 1s or 2s (for the hours), and the y-axis by 20s (for the cost

this is a true or false thing for geometry
Answers
2) If two angles are 45 degrees then they are complementary and congruent.
Explanation: Complementary angles add up to 90 degrees and congruent angles are angles that are equal. Two 45 degree angles are equal to each other and add up to 90 degrees. The first statement is false because there are many combinations of angles that add up to 90 degrees that are not the same. (30 degrees and 60 degrees)
