Answer:
It can go 250 m deep
Step-by-step explanation:
Using a system of equations, it is found that the numbers are 5 and -7.
<h3>What is a system of equations?</h3>
A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
In this problem, we say that the numbers are x and y.
They multiply to -35, hence:
xy = -35.
They add to -2, hence:
x + y = -2 -> y = -2 - x
Replacing on the first equation:
x(-2 - x) = -35
-x² - 2x + 35 = 0
x² + 2x - 35 = 0
(x + 7)(x - 5) = 0
x = -7 -> y = 5
x = 5 -> y = -7
Hence the numbers are 5 and -7.

Answer:
i believe m<1 = 45°
Step-by-step explanation:
180 is half a circle then divide by the number of pieces which is 4
It's 90pi m^2 I just used a online SA cone calculator. otherwise you need to know or look up the formula and put in the radius and height.
