One positive number exceeds another by 2, and their product is 80. Find the numbers​
katen-ka-za [31]

Answer:

The Answer is: The first number is 10 and the second number is 8.

Step-by-step explanation:

Let f = first number and s = second number.

The first number is 2 larger than the second:

f = n + 2

The numbers times each other is 80:

f * n = 80

Substitute the value of f, which is (n + 2):

n(n + 2) = 80

n^2 + 2n = 80

n^2 + 2n - 80 = 0

(n + 10)(n - 8) = 0

n^2 + 10n - 8n - 80 = 0, so the first number is 10 and the second one is 8.

Another method, just from thinking about it:

factor 80:

8 * 10, is the first factoring I thought of. I then noted that the difference between the two is 2 and if you multiply them they equal 80.

Hope this helps! Have an Awesome Day!! :-)

Please help I will give brainliest to the right answer!!!
timama [110]

Answer:

Step-by-step explanation:

Given function l:

h= -16t² + 26t

where h represents height and t represents time.

The time for dolphin atbthe height 5 feet is given by putting the value of h as 5 in the function,

5 = -16t² + 26t

16t² - 26t + 5 = 0

For this equation: a=16, b=-26, c=5

Use quadratic formula with a=16, b=-26, c=5.

x=(−b±√b2−4ac)/2a

x=−(−26)±√(−26)2−4(16)(5)/2(16)

x=13/16 + 1/16√89 or x=13/16+ −1/16√89

x=1.40 or 0.22
