Check the picture below.

notice AB ⟂ BC , whilst ∡B = 30°.

now, if we run a perpendicular line from C to AB, it'll be a 90° angle at M, however ∡AMC has to be 105°, so it has to be slanted more towards A, like in the picture, and surely you already know which one is the shortest.

hammer [34]

Answer:

See below ~

Step-by-step explanation:

Drawing the rectangle (Refer attachment)

Horizontal sides

There are two x-values present : 1 and 6
Find the difference
6 - 1 = 5
The horizontal sides of the rectangle are 5 units long

Vertical sides

Two y-values are present : 4 and 5
Find the difference
5 - 4 = 1
The vertical sides of the rectangle are 1 unit long

Perimeter

2(Horizontal side + Vertical side)
2(5 + 1)
2(6)
12
The perimeter of the rectangle is 12 units

Chapter 8 Written Homework 1. A hypothesis test is conducted to test the claim that the proportion of people with dark hair at M

UNO [17]

Answer:

we reject H₀

Step-by-step explanation: Se annex

The test is one tail-test (greater than)

Using α = 0,05 (critical value ) from z- table we get

z(c) = 1,64

And Test hypothesis is:

H₀ Null hypothesis μ = μ₀

Hₐ Alternate hypothesis μ > μ₀

Which we need to compare with z(s) = 2,19 (from problem statement)

The annex shows z(c), z(s), rejection and acceptance regions, and as we can see z(s) > z(c) and it is in the rejection region

So base on our drawing we will reject H₀

1-cos^2 A / sec^2 A - tan^2 A

tiny-mole [99]

I hope this helps you

✔cos^2A+sin^2A=1

✔1-cos^2A=sin^2A

✔cos2A=cos^2A-sin^2A

✔sin2A=2.sinA.cosA

secA=1/cosA

tgA=sinA/cosA

sin^2A/1/cos^2A-sin^2A/cos^2A

sin^2A.cos^2A/cos2A

2.sin^2A.cos^2A/cos2A

sin2A.2.sin2A/cos2A

tg2A.2.sin2A

Adds up to 13 multiplies to -48

fiasKO [112]

You only need two numbers to do that.
The numbers are 16 and -3 .

16 - 3 = 13

(16) x (-3) = -48
