Find sin X, sin Z, cos X, and cos Z. Write each answer as a simplified fraction.
just olya [345]

Answer:

Find the answers below

Step-by-step explanation:

Using m<X as the reference angle

Opposite YZ = 7

Adjacent  XY = 10

Hypotenuse XZ = √149

Using the SOH CAH TOA identity

sinX = opp/hyp

sinX =YZ/XZ

sinX = 7/√149

For cos X

cos X = adj/hyp

cos X =10/√149

Using m<Z as reference angle;

Opposite XY = 10

Adjacent  YZ = 7

Hypotenuse XZ = √149

Using the SOH CAH TOA identity

sinZ = opp/hyp

sinZ =10/√149

sinZ = 7/√149

For cos Z

cosZ = 7/√149

Describe how to determine the average rate of change between x = 3 and x = 5 for the function f(x) = 3x3 + 2. Include the averag
Anit [1.1K]

Answer:

<u><em>I HOPE IT WILL WORK</em></u>

Step-by-step explanation:

As  for average rate of change we know

A(x)=f(5)-f(3)/(5-3)

where

f(x)=3 x 3 + 2       (1)

putting x=5 we get

f(5)=3(125)+2 =377

f(3)=83

hence putt in (1)  we get

A(x)=294/2 =146

this is required average rate of change

What is the length of segment TQ?
oksano4ka [1.4K]

Answer: 14

Step-by-step explanation:

We know that \triangle SRV \con \triangle QRV by SAS, so this means QV=SV by CPCTC. Hence, 4x-1 \longrightarrow x=4.

We also know that \triangle STR \cong \triangle QTR by SAS, so this means TS=TQ by CPCTC. Since TS=3x+2=3(4)+2=14, <u>TQ=14.</u>
