y = abx

Point (1, 4): 4 = ab

Point (3, 16): 16 = ab^3

From 4=ab we have a = 4/b

Substitute into 2nd equation

16 = (4/b)b^3

16 = 4b^2

4 = b^2

2 = b

a = 4/b = 4/2 = 2

An exponential function that fits is: y = 2(2^x)

check: x=1; y = 2(21) = 4 ... point (1, 4)

x=3: y = 2(23) = 2(8) = 16 ... point (3, 16)

∠BAD is bisected by . If m∠BAC= 2x - 5 and m∠CAD = 145, the value of x is 150 145 75 70
horsena [70]
We are asked to find the value of x given that ∠BAD is bisected by AC and measurement of BAC is equal to 2x - 5 and measurement of CAD is equal to 145. Since they are bisected, they are equal and the solution is shown below:
m ∠ BAC = m ∠ CAD
2x - 5 = 145 , transpose -5 to the opposite side such as:
2x = 145 + 5 , perform addition of 145 and 5
2x = 150
2x / 2 = 150 / 2 , divide both sides by 2
x = 75

The answer is 75 for the x value.

The function h(x) is given below.
viva [34]

The inverse function will be h⁻¹(x) = { ( 3, -5 ) , ( 5, -7),( 6 ,-9),( 10,-12),(12,-16)}.

<h3>What is function?</h3>

A function is defined as the expression that set up the relationship between the dependent variable and independent variable.

Given function is:-

h(x) = {(3, –5), (5, –7), (6, –9), (10, –12), (12, –16)}

The inverse function is given as:-

h(x,y) = h⁻¹( y,x )

So the inverse function will be:-

h⁻¹( x, y ) = { ( 3, -5 ) , ( 5, -7),( 6 ,-9),( 10,-12),(12,-16)}.

Therefore  inverse function will be h⁻¹(x) = { ( 3, -5 ) , ( 5, -7),( 6 ,-9),( 10,-12),(12,-16)}.
