Answer:

The slope of the given linear function is -4.

Step-by-step explanation:

We have been given the linear equation $y=-4x-9$

The slope intercept form of a line is given by $y=mx+b$

Here, b is y-intercept and m is the slope.

On comparing, the given equation with the slope intercept form, we get

b = -9

m = -4

It means that the y-intercept is -9 and the slope of the line is -4.

Therefore, the slope of the given linear function is -4.

b] In the opposite figure : XYZL is a square, XZ = 10 cm. , m(L XZY) = 43° Calculate the perimeter of triangle XYZ

scoray [572]

Answer:

Perimeter of Δ XYZ = 24.13

Step-by-step explanation:

In Δ XYZ is a right triangle because the XYZL is a square. Therefore the hypotenuse = 10; Looking at the 43° angle, XY is the side that is opposite the 43° angle and the YZ is the side that is adjacent to the 43°.

Using the trig ratios:

XY = opposite/ hypotenuse which is Sin 43°

Sin 43° = XY/ 10

10(Sin 43°) = XY

6.82 = XY

YZ = adjacent/hypotenuse which is Cos 43°

Cos 43° = YZ/10

10(cos 43°) = YZ

7.31 = YZ

Now the Perimeter = XY + YZ + XZ

Perimeter = 6.82 + 7.31 + 10

Perimeter = 24.13

Find the value of the length x rounded to 1 DP.

ivanzaharov [21]

Answer:

x = 13.6 cm

Step-by-step explanation:

part A:

using tan rule:

$tan(x) = \frac{opposite}{adjacent}$

$tan(39) = \frac{6}{adjacent}$

$adjacent = \frac{6}{tan(39)}$

$adjacent = 7.41$

part B:

using tan rule:

$tan(x) = \frac{opposite}{adjacent}$

$tan(44) = \frac{6}{adjacent}$

$adjacent = 6.213$

Total length of x:

part A + part B

$7.41 + 6.213$

$13.6$ cm

A ray of light passing from air through an equilateral glass prism undergoes minimum

Mama L [17]

Answer: 45° and speed of light in prism 2×10⁸m/s

Step-by-step explanation:

The minimum deviation of the equilateral glass prism will form 60° angle.

So angle of incidence = 3/4×60

= 3 ×15

= 45°

Minimum deviation = δmin

= 30

After finding the value of μ using prism law

μ = 1.41

Speed of light will be 2×10⁸m/s
