Given sec A = 5/3 and that angle A is in Quadrant I, find the exact value of csc A in simplest radical form using a rational den

Answer:

5/4

Step-by-step explanation:

The relationship between the sec and csc functions is ...

csc(A) = sec(A)/√(sec²(A) -1)

For the given value of sec(A), this is ...

csc(A) = (5/3)/√((5/3)² -1) = (5/3)/√(16/9) = (5/3)/(4/3)

csc(A) = 5/4

Some calculators can tell you the answer directly.

F(x) = 2x+1/×-1 find the inverse function

denis23 [38]

To factor this, start by replacing x with y and then solve for y
$f(x) = \frac{2x+1}{x - 1}$
$x = \frac{2y+1}{y - 1}$
$(y-1)x = \frac{2y+1}{y - 1} * (y-1)$
$(y-1)x = 2y+1$
$xy -x = 2y+1$
$xy - 2y -x +x = 2y - 2y +x+1$
$xy - 2y = x+1$
Factor out y on the left side.
$\frac{xy - 2y}{y} = x+1$
$y(x - 2) = x+1$
$\frac{y(x - 2)}{(x-2)} = \frac{x+1}{x-2}$
$y = \frac{x+1}{x-2}$
$f(x)^{-1} = \frac{x+1}{x-2}$

The diagram shows the net of a juice box. The box is a rectangular prism.

Hoochie [10]

Answer:

269.6 square centimeters

Step-by-step explanation:

The correct question is

The diagram shows the net of a juice box. the box is a rectangular prism. what is the surface area of the juice box? 6.4 cm 4 cm 10.5 cm

we know that

The surface area of a rectangular prism is equal to

$SA=2B+PH$

where

B is the area of the base

P is the perimeter of the base

H is the height of the prism

we have

$L=6.4\ cm\\W=4\ cm\\H=10.5\ cm$

Find the area of the base B

$B=LW$

substitute the given values

$B=(6.4)(4)=25.6\ cm^2$

Find the perimeter of the base P

$P=2(L+W)$

substitute the given values

$P=2(6.4+4)=20.8\ cm$

Find the surface area

$SA=2B+PH$

substitute

$SA=2(25.6)+(20.8)10.5=269.6\ cm^2$

Your classmate wants you to check her work. She is working on a math question that asks her to determine the slope of a line giv

Hitman42 [59]

The answer of my classmate that the line has a positive slope is CORRECT. This is because the line is most likely to lean to the right. The slope can be calculated through the equation,
slope = rise / run = change in y / change in x
If both are negative, the slope is POSITIVE.
