Answer:
1.
y = 20(11) + 300 = 520
y = 5(11)(11) = 605
y = 10(1.4)^11 = 404.96
hence the quadratic formula - y = 5x^2 has the largest y-value
2.
y = 20 (14) + 300 = 580
y = 5 (14) (14) = 980
y = 10(1.4)^ 14 = 1111.20 > this is greater than both equations above
14 is the smallest value of x for which the value of the exponential equation is greater than the values of both the linear and quadratic functions
Step-by-step explanation:
Use the Pythagorean theorem:
x = √(12.7^2 - 6.2^2)
x = √(161.29 - 38.44)
x = √122.85
x = 11.08
Round to 11.1 m
Answer:
<h3>
97, 485 and 197</h3>
Step-by-step explanation:
x - the first number
One number is 5 times a first number:
5x - "one" number (the second number)
A third number is 100 more than the first number:
x + 100 - the third number
x + 5x + x+100 - the sum of the three numbers
x + 5x + x+100 = 779
-100 -100
7x = 679
÷7 ÷7
x = 97
5x = 5•97 = 485
x+100 = 97 + 100 = 197
Check:
97 + 485 + 197 = 779
