It is 18 degrees Celsius at 8 am, and 14 degrees Celsius by noon. The change in the temperature from 8am to noon is?
Oliga [24]

Answer:

4 degrees Celsius

Step-by-step explanation:

It is asking for the change in temperature, or the difference. In word problems like this it is asking for subtraction.

So you just need to subtract the temperature at noon from the temperature at 8 am.

18 - 14 = 4 degrees

Factor out the coefficient of the variable 2.2x+4.4
OleMash [197]
The coefficients are the numbers in front of x or the 4.4 in the equation. So you can just divide the numbers.

2.2x + 4.4                Divide to 2.2
x + 2

Select the correct texts in the table.
ra1l [238]

Based on the given texts in the table about the graph of the function, the true statements are:

  • The graph crosses the y-axis at (0,-15).
  • The graph has a point of discontinuity at x = -2.
  • The graph is increasing over the interval (4, ∞o).
  • The domain of the function is all real numbers.

<h3>Which statements are true of the graph of the function?</h3>

The function, 4x - 15 shows that 15 is the y-intercept which means that the graph will cross the y-axis at (0,15).

The point of discontinuity is x = - 2 and we see this with the gap created at x < -2 and -2 ≤ x ≤ 4.

The graph is indeed increasing over the interval (4, ∞o) because any value of x that is greater than 4 will increase f(x) = 3^x^-^4.

The domain of the function is also all real numbers as it begins at negative infinity and ends at infinity, (-∞, ∞).

What is the maximum slope to f(x)= e^(-x^2)?
MA_775_DIABLO [31]
F'(x)=-2x{e^(-x²)}
Equating f'(x)=0,
i.e,

-2x{e^(-x²)}=0....eqn(i)
For maximum slope:
Differentiating (i) wrt x,we get,
4x² {e^(-x²)}-2 {e^(-x²)}=0
{e^(-x²)} [4x²-2]=0
4x²-2=0
x=1/√2

If f(x)=y then f'(x)=dy/dx=slope
So,
Maximum slope
= f'(x)
= -2x{e^(-x²)}
=-2×(1/✓2){e^(-1/✓2)²}
= -✓2{e^(-1/2)}
=(-sqrt 2/sqrt e)
=-sqrt(2/e)➡c is correct
