What is the range of y = –5sin(x)?
sergejj [24]

Answer:

-5\leq y\leq5  is the required range.

Step-by-step explanation:

We have been given a function:

y=-5sin(x)

The range of sin x is -1\leq sinx\leq1

multiply -5 in each term of the above equation.

-1(-5)\geq -5sinx\geq-5

\Rightarrow 5\geq -5sinx\geq-5

Hence, the required range is:

-5\leq -5sinx\leq5

replace -5sinx by y so, we get:

-5\leq y\leq5

Someone please help me make a proof for the bottom question
Lerok [7]

Answer:

DB = CA (Proved)

Step-by-step explanation:

Statement 1.

∠D = ∠C, M is the midpoint of DC and ∠1 = ∠2

Reason 1.  

Given

Statement 2.

Between Δ DBM and Δ CAM,  

(i) DM = CM,

(ii) ∠D = ∠C  and  

(iii) ∠DMB = ∠CMA

Reason 2.

(i) given  

(ii) given and  

(iii) ∠ DMB = ∠1 + ∠AMB and  ∠CMA = ∠2 + ∠AMB

Since ∠1 = ∠2, so, ∠DMB = ∠CMA.

Statement 3.

Δ DBM ≅ Δ CAM

Reason 3.

By angle-side-angle rule.

Statement 4.

DB = CA

Reason 4.

Corresponding sides of two congruent triangles. (Answer)
