Helpp!!!<br> prove that:<br> cosecA-cotA= tanA/2
romanna [79]

Answer:

tanA/2.

Step-by-step explanation:

some trigonometric properties:

* tanA = sinA/cosA

* secA = 1/cosA

* cscA = 1/sinA

* cotA = cosA/sinA

1/sinA - cotA

1/sinA - cosA/sinA

1 - cosA / sinA

.... 1 - cosR / sinR = tan(R/2)

1 - cosA / sinA

= tanA/2.

devlian [24]

Answer:

B. 3 square feet

Step-by-step explanation:

The formula for surface area is:

2lw+2lh+2wh

Box F's surface area is just plugging in those variables

2(3)(3)+2(3)(3)+2(3)(3)=54

Box J's surface area is the same way

2(2)(4.5)+2(2)(3)+2(4.5)(3)=57

The difference is 57-54=3

The answer is B. 3 square ft

1.5/4x+1=0.4/x+4 PLEASE HELP ITS PROPORTIONS
Serhud [2]

Answer:

Proportion states that the two fractions or ratios are equal

Given the equation:  \frac{1.5}{4x+1} = \frac{0.4}{x+4}

By cross multiply we get;

1.5(x+4) = 0.4(4x+1)

Using distributive property; a\cdot (b+c) = a\cdot b+ a\cdot c

1.5x + 6= 1.6x + 0.4

Subtract 0.4 from both sides we get;

1.5x +5.6= 1.6x

Subtract 1.5x from both sides we get;

5.6= 0.1x

Divide both sides by 0.1 we get;

x = \frac{5.6}{0.1}

Simplify:

x = 56

Therefore, the value of x that satisfy the equation \frac{1.5}{4x+1} = \frac{0.4}{x+4} is, 56

Lynette wanted to run one mile in eight minutes. To be on pace to reach
natta225 [31]

Answer:

0.25 miles

Step-by-step explanation:

assuming that she keeps a constant Velocity/ speed,

find the speed she intends to run with, ie total distance/time

\frac{1}{8} miles \: per \: minute

find the distance she travels in two minutes, ie speed multiplied by time.

\frac{1}{8}  \times 2 =  \frac{1}{4 }  = 0.25
