Last week at the lake it’s was 23 degrees celsius today it is 13 degrees warmer what is today day’s temperatures

36 degrees

Step-by-step explanation:

We are given that last week at the lake, the temperature was 23 degrees and today it is 13 degrees warmer and we are to find what is the temperature today.

Since the temperature has gone higher so it means that we need to add 13 degrees to previous week's temperature in order to find today's temperature.

Today's temperature = 23 + 13 = 36 degrees

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.

the red lines denote the population of the bacteria after 35 hours. that would be 2,409.24. the y-intercept is the blue line which is 800 because that is the starting point. the equation used to make the graph is 800(1.032)^h, where h is the number of hours.
