Answer:

x= 56 degree

Step-by-step explanation:

sin x= opposite/ hypotenuse

sin x= 66/79

sin x=0.84

sin-1(0.84)= x

x= 56 degree

The slope of the line below is -1. write the point-slope equation of the line using the coordinates of the labeled point.

omeli [17]

Answer:

y+9=-1(x-4)

Step-by-step explanation:

Point Slope Form is:

$y-y_1=m(x-x_1)$

When:

'm' is the slope.

$(x_1,y_1)$ is the coordinate.

We are given the slope of -1 and the coordinate of (4,-9).

So:

$m=-1\\x_1=4\\y_1=-9$

Using the information and replacing the values we get:

$y+9=-1(x-4)$

So, the line equation in point slope form should be: y+9=-1(x-4)

Verifying Properties of logarithms In Exercise,use a graphing utility to verify that the functions are equivalent for x > 0.

Ede4ka [16]

Answer:

Applying Quotient and power rule. Graphically, for x>0 both curves coincide.

Step-by-step explanation:

1) Firstly, by applying the Quotient and then the Power Rule, we have a subtraction of the argument and, finally the exponent turns to be the coefficient. As it follows:

$lnx=log_{e}x\\\\f(x) = ln({\frac{x^{2}}{4}})\Rightarrow f(x)=ln{x^2}-ln4\Rightarrow f(x)=2lnx-ln4\\g(x) = 2 ln x - ln 4$

2) Check the graph below to see this equivalence. to see x>0 they both coincide.

Perimeter is 24.

Length is 4 greater than the width.

Let's use 'x' for width

we can write this as x+4 + x+4 + x + x

x+4 being the width+4 and x being the width

There are 4 sides to a rectangle so you are adding 4 values

Two length and two widths

so we can then combine the two lengths to make 2x+8

and then combine the two widths to make 2x

Then put it together. 2x+2x+8= 4x+8

4x+8=24

Subtract 8 from both sides

4x=16

divide both sides by 4

x=4

The width is 4.
