Answer:

Step-by-step explanation:

Prove that

sec(x) - sin(x)tan(x)=cosx

sec(x)=1/cos(x) tan(x)=sin(x)/cos(x)

1/cos(x) - sin(x) x sin(x)/cos(x)

(1-sin(x) x sin(x))/cos(x)

(1-sin^2(x))/cos(x) 1-sin^2(x)=cos^2(x)

Cos^2(x)/cos(x)

(Cos(x) x cos(x))/cos(x)

cos(x) proved

Triangle ABC is transformed to create triangle MNO and triangle PQR as described below.
Alik [6]

The missing options are located here; brainly.com/question/18156103

The option that correctly describes the transformation that took place with triangle ABC is; <u><em>Option A.</em></u>

  • In transformations, translation simply means shifting an object from one position to the other while dilation simply means increasing or decreasing an object by a scale factor.
  • This means that translation preserves the lengths and angles of the object while the lengths and angles change with dilation.

Option A; Triangle MNO represents a translated triangle and as such the lengths and angles remain unchanged and so this option is correct.

Option B; Not true because both lengths and sides are preserved as stated above.

Option C; Transformation to PQR denotes dilation by a factor of 2 and as such the lengths and angles change. Thus this option is not true.

Option D; This is not true for the same reason in option C above.

If three times a number plus four is no more than four times the number minus one, which of the following are true? Let z repres
Ahat [919]

Answer:

z\geq 5

The number is at least 5

Step-by-step explanation:

Let

z -----> the number

we know that

The inequality that represent this problem is

3z+4 \leq 4z-1

because, the phrase "no more than" is the same that "less than or equal to"

Solve for z

4+1 \leq 4z-3z

5 \leq z

Rewrite

z\geq 5

therefore

The number is at least 5.
