Answer:

41

Step-by-step explanation:

We can obtain the area of a triangle where two sides and an included angle is given by saying; 1/2 ab sinθ

where a and b are the given sides of the triangle and θ is the included angle.

From the formula for the area of the triangle;

Area of a triangle = 1/2 ac sin B

Area of the triangle = 1/2 * 9 * 11 * sin 124

Area of the triangle = 49.5 * sin 124

Area of the triangle =  41

Write the equations of the line that passes through the point 4,3) and is perpendicular to the line y=2x−4 . Write the equation
Anon25 [30]

Answer:

<h2>         y = -¹/₂x + 5</h2>

Step-by-step explanation:

The product of slopes of perpendicular lines is -1

y = 2x − 4  ⇒   m₁ = 2

m₁m₂ = -1

2m₂ = -1

m₂ = -¹/₂

The Point-Slope form of equation of a line with slope of "m" and passing through point (x₁, y₁) is:  y - y₁ = m(x - x₁)

m = -¹/₂

(4, 3)  ⇒  x₁ = 4,  y₁ = 3

So the equation in point-slope form:

                                                  y - 3 = -¹/₂(x - 4)

Therefore:

y - 3 = -¹/₂x + 2

y = -¹/₂x + 2 + 3

<h3>y = -¹/₂x + 5</h3>

if the edwards drive 225 miles, which company would be a better deal? if the edwards only have to spend, which company would be
VikaD [51]

i can give you the exact answer to your question, but what are the equations for the companies and  how much do the edwards have to spend? if not, here's how to do it:

y= m(225)+b for each company. i used slope-intercept form assuming that's what form the equations are written in. it's basically saying x=225 in part a (look for the lowest y) and in part b y≥m(225)+b (look for which company's equation makes the statement true)

(ps i'm checking every few minutes if you want to comment and get the exact answer)

((2x^9)(y^n))((4x^2)(y^10))=(8x^11)(y^20)
tino4ka555 [31]

We are given

((2x^9)(y^n))((4x^2)(y^{10}))=(8x^{11})(y^{20})

Firstly, we simplify left side

Left side is

((2x^9)(y^n))((4x^2)(y^{10}))

we will make all x terms together

and y terms together

(2x^9)(4x^2)(y^n)(y^{10})

2\times 4(x^9)(x^2)(y^n)(y^{10})

8(x^9)(x^2)(y^n)(y^{10})

we can multiply left side by using exponent rule

a^m\times a^n=a^{m+n}

8(x^{9+2})(y^{n+10})

8(x^{11})(y^{n+10})

now, we can set them equal

(8x^{11})(y^{n+10})=(8x^{11})(y^{20})

Since, both sides have x,y and 8

and both are equal

so, their exponent must be equal

so, exponent of y must also be equal

we get

n+10=20

n=10................Answer
