Answer:

There are three condition, where determinant can be zero. If the complete row of a matrix is zero. If any row or column of a matrix is the constant multiple of another row or column. If any two rows or columns are equal.If all the elements of a row (or column) are zeros, then the value of the determinant is zero. ) is 1.

Differentiating Exponential functions In Exercise,find the derivative of the function. See Example 2 and 3.

Citrus2011 [14]

Answer:

$f'(x)=-5ae^{ax}=a f(x)$ , where a be a constant.

Step-by-step explanation:

Note: The given functions is a constant function because variable term is missing.

Consider the given function is

$f(x)=-5e^{ax}$

where a be a constant.

We need to find the derivative of the function.

Differentiate with respect to x.

$f'(x)=\dfrac{d}{dx}(-5e^{ax})$

$f'(x)=-5\dfrac{d}{dx}(e^{ax})$

$f'(x)=-5e^{ax}\dfrac{d}{dx}(ax)$ $[\because \dfrac{d}{dx}(e^x)=e^x]$

$f'(x)=-5ae^{ax}$

$f'(x)=a(-5e^{ax})$

$f'(x)=a f(x)$

Therefore, the derivative of the function is $f'(x)=-5ae^{ax}=a f(x)$ .

C. Find the value of X. Show your work. Congruent triangles

Dmitriy789 [7]

Answer:

Step-by-step explanation:

1) 97 + x = 64 + 27 {Exterior angle property}

97 + x = 91

x = 91 - 97

x = -6

2) 4x + 17 + 80 + x + 23 = 180 {Angle sum property of triangle}

4x + x + 17 +80 + 23 = 180

5x + 140 = 180

5x = 180 - 140

5x = 40

x = 40/5

x = 8
