Find the value of x. Round to the nearest tenth.
Aliun [14]

Answer:

Step-by-step explanation:

Triangle XYZ is a right angle triangle.

From the given right angle triangle

XZ represents the hypotenuse of the right angle triangle.

With ∠34 as the reference angle,

YZ represents the adjacent side of the right angle triangle.

XY represents the opposite side of the right angle triangle.

To determine x, we would apply the Cosine trigonometric ratio

Cos θ = opposite side/hypotenuse. Therefore,

Cos 34 = x/28

x = 28Cos34 = 28 × 0.8290

x = 23.212

To the nearest tenth, it becomes

23.2

identify the equation in the point-slope form the line parallel to y=3/4x-4 that passes through (-1,7)
hram777 [196]
Y = 3/4x -4
The slope is 3/4 since it is written in the form y =mx+b where m is the slope
We want a line that is parallel so it will have the same slope
We know the slope of the new line (3/4) and a point (-1,7)
So we can use the point slope form of the equation
y-y1 = m(x-x1)
y-7 = 3/4(x--1)
y-7=3/4(x+1)

Find the values of m for which the lines y=mx-2 are tangents to the curve with equation y=x^2-4x+2
deff fn [24]

Let y= mx-2 be the tangent line to y=x^2-4x+2 at x=a.

Then slope, m=\frac{dy}{dx} at x=a = 2a-4.

Hence the equation is y=(2a-4)x-2

Let's find y-coordinate at x=a using tangent line and curve.

Using tangent line y at x=a is (2a-4) a -2 =2a^{2}-4a-2

Using given curve y-coordinate at x=a is a^{2}-4a+2

Let's equate these 2 y-coordinates,

 2a^{2} -4a-2 = a^{2} -4a+2

2a^{2}-a^{2} = 2+2

a^{2}=4

a=2 or -2.

If a=2, m=2a-4 = 2*2-4=0

If a=-2,m= 2(-2)-4 = -8

Hence m values are 0 and -8.
