An unknown number is not equal to 3.6 but rounds to 3.6 when rounded to the nearest tenth, what could be the number?

Answers

Answer:

3.55-3.59

Step-by-step explanation:

to round off to the nearest whole number, look at the first number after the decimal, if it is less than 5, add zero to the units term, If it is equal or greater than 5, add 1 to the units term.

So numbers that would be rounded off to 3.6 have to have an hundredth value equal or greater than 5

they include

Answer:

Sin A = 5/13; tan C = 12/5

Step-by-step explanation:

Sin = opposite / hypotenuse. The opposite of A is 5, and the hypotenuse is 13, therefore Sin A = 5/13.

Tan = opposite / adjacent. The opposite of C is 12, and the adjacent is 5, so tan C = 12 / 5

A 4 pound force acting in the direction of (4,-2) moves an object just over 7 ft from point (0,4) to point (5,-1). Find the work done to move the object to the nearest foot-pound

Answers

Answer:

[tex]W=59.7408J[/tex]

Step-by-step explanation:

From the question we are told that:

Force [tex]f=4N[/tex]

Force Direction [tex]\arrow (4,-2)[/tex]

Distance traveled [tex]d_t=7ft \aprrox\ 2.1336m[/tex]

Distance traveled Direction point (0,4) to point (5,-1)

 

Generally the equation for work done is mathematically given by

 [tex]W=force*distance[/tex]

 [tex]W=f*d_t\\W=4*7*2.1336[/tex]

 [tex]W=59.7408J[/tex]

Given that sec0=-37/12, what is the value of cot0, for pi/2<0

Answers

Answer:

2nd option

Step-by-step explanation:

Using the identities

tan²θ + 1 = sec²θ

cotθ = [tex]\frac{1}{tan0}[/tex]

Given

secθ = - [tex]\frac{37}{12}[/tex] , then

tan²θ + 1 = (- [tex]\frac{37}{12}[/tex] )² = [tex]\frac{1369}{144}[/tex] ( subtract 1 from both sides )

tan²θ = [tex]\frac{1225}{144}[/tex] ( take the square root of both sides )

Since [tex]\frac{\pi }{2}[/tex] < θ < π and tanθ < 0 , then

tanθ = - [tex]\frac{35}{12}[/tex]

Then

cotθ = [tex]\frac{1}{-\frac{35}{12} }[/tex] = - [tex]\frac{12}{35}[/tex]

Expand the parenthesis using the distributive law;

[tex]\frac{1}{2}(10x)+ \frac{1}{2}(20y)+\frac{1}{2}(10z)\\= \frac{10x}{2} + \frac{20y}{2} + \frac{10z}{2}\\= 5x + 10y + 5z[/tex]
