Answer:

Step-by-step explanation:

Since Θ is in the fourth quadrant where cosΘ > 0

The only positive values are B / D

since 0 < cosΘ < 1

$\frac{\sqrt{41} }{5}$ > 1 then

D is the appropriate response

Answer:

Step-by-step explanation:

option A and B can not be because square root of 41 is irrational number option C can not be because in 4th quadrant cos is positive so option D is correct.

An arithmetic sequence is defined by the recursive formula t1 = 11, tn = tn - 1 - 13, where n ∈N and n > 1. Which of these is

galben [10]

coolio

$t_1=11$

$t_n=t_{n-1}-13$

so each term is ound by subtracting 13 from the previous term

an aritmetic sequence can be written as

$t_n=t_1+d(n-1)$ were

$t_n$ is the nth term

$t_1$ is the first term

d is common difference, which can also be found by doing $t_n-t_{n-1}=d$

n=wich term

we know that $t_1=11$ and we can find d

$t_n=t_{n-1}-13$ , $t_n-t_{n-1}=-13=d$

so te general term is $t_n=11-13(n-1)$ which can also be expanded and written as $t_n=-13n+24$

What is the value of x

timama [110]

Answer:

The answer to your question is: x = 27

Step-by-step explanation:

The are vertical angles, so they measure the same:

4x + 7 = 5(x - 4)

4x + 7 = 5x - 20 Expanding

4x - 5x = -20 - 7 Simplify like terms

-x = -27

x = 27

The tires on a new compact car have a diameter of 2.0 ft and are warranted for 63,000 miles. (a) Determine the angle (in radians

Damm [24]

Answer:

Tire will be warranted for $3.326\times 10^8radian$

Step-by-step explanation:

We have given that tire is warranted for 63000 miles

We know that 1 mile = 5180 feet

So $63000miles=63000\times 5280=3.3264\times 10^8feet$

Diameter is given d = 2 feet

So radius $r=\frac{d}{2}=1feet$

Angular distance is given by $\Theta =\frac{linear\ distance}{radius}=\frac{3.326\times 10^8}{1}=3.326\times 10^8radian$
