<h2>Answer :</h2>

The original price is x, so 20% of x, - x, equals the sale price. You can use the equation:

x-.2x=15.20

.8x=15.20

The exponential function y= a(b)^x passes through the points (3,25) and (8,10). Which of the following is closest to the value o
Yuki888 [10]

If the exponential function y=ab^x passes through the points (3,25) and (8,10), the value of b is 0.833

The given exponential equation is:

y=ab^x

The function passes through the points (3, 25) and (8, 10)

Substitute x = 3 and y = 25 into the function y=ab^x

25=ab^3............................(1)

Substitute x = 8 and y = 10 into the function y=ab^x

10=ab^8.............................(2)

Divide equation (2) by equation (1)

\frac{10}{25}=\frac{ab^8}{ab^3}  \\\\0.4=b^5\\\\b=0.4^\frac{1}{5} \\\\b=0.4^{0.2}\\\\b=0.833

Therefore, if the exponential function y=ab^x passes through the points (3,25) and (8,10), the value of b is 0.833

Which of the following would be an acceptable first step in simplifying the expression tanx/1+ secx
djverab [1.8K]

The acceptable first step in simplifying the expression \mathbf{\frac{tan\ x}{1 + sec\ x}} is (a) \mathbf{\frac{tan\ x(1 - sec\ x)}{(1 + sec\ x)(1 - sec\ x)}}

The expression is given as:

\mathbf{\frac{tan\ x}{1 + sec\ x}}

To change the form of the expression, we simply perform several arithmetic operations on it.

Start by multiplying the expression by 1/1

\mathbf{\frac{tan\ x}{1 + sec\ x} = \frac{tan\ x}{1 + sec\ x} \times \frac 11}

Express 1 /1 as (1 - sec x)/(1 - sec x)

\mathbf{\frac{tan\ x}{1 + sec\ x} = \frac{tan\ x}{1 + sec\ x} \times \frac{1 - sec\ x}{1 - sec\ x}}

Rewrite the above expression as follows:

\mathbf{\frac{tan\ x}{1 + sec\ x} = \frac{tan\ x(1 - sec\ x)}{(1 + sec\ x)(1 - sec\ x)}}

Hence, the acceptable first step is (a)
