Trigonometric Functions:

$S\frac{O}{H} C\frac{A}{H} T\frac{O}{A}$

$Sine\frac{Opposite}{Hypotenuse} Cos\frac{Adjacent}{Hypotenuse} Tan\frac{Opposite}{Adjacent}$

You have the angle and the adjacent. You need to find the hypotenuse (PR). Therefore, you use cos.

$Cos(26)=\frac{13}{H}$

Rearrange the formula to find H (PR):

$H = \frac{13}{Cos(26)}$

The dosage for a drug used to treat a male Siberian tiger that weighs 550 pounds is based on the tiger's weight in kilograms (kg

algol [13]

Answer:

227.2727 kilograms

Step-by-step explanation:

The tiger weight is 550 pounds, and we want to convert this value to kilograms, so we need to use the ratio between pounds and kilograms.

We know that 1 kilogram is equal to 2.2 pounds, so we can solve this problem using a rule of three:

1 kilogram is equal to 2.2 pounds,

X kilograms are equal to 550 pounds.

1/X = 2.2/500

X = 500/2.2 = 227.2727 kilograms

So the weight of the tiger in kilograms is 227.2727 kilograms.

Solving Exponential and Logarithmic Equations In Exercise, solve for x.<br> 500(1.075)120x = 100.000

Volgvan

Answer:

The solution is:

$x = 0.61$

Step-by-step explanation:

The first step to solve this equation is placing everything with the exponential to one side of the equality, and everything without the exponential to the other side. So

$500(1.075)^{120x} = 100000$

$(1.075)^{120x} = \frac{100000}{500}$

$(1.075)^{120x} = 200$

To find x, we have to apply log to both sides of the equality.

We also have that:

$\log{a^{x}} = x\log{a}$

$\log{(1.075)^{120x}} = \log{200}$

$120x\log{1.075} = 2.30$

$120x*0.03 = 2.30$

$3.77x = 2.30$

$x = \frac{2.30}{3.77}$

$x = 0.61$

Turn y=6x-5 (explicit) into a recursive equation

worty [1.4K]

Answer:

$a_1=1\\a_n=a_{n-1}+6$

Step-by-step explanation:

So to define a recursive equation, you need to find how much each term is increasing or decreasing by. You also need to find the first term. To find the first term you can simply plug in 1 into x: $a_1=6(1)-5 = 6-5 = 1$ . And as you can see the slope is 6, so each term is increasing by 6. So you get the recursive function: $a_1=1\\a_n=a_{n-1}+6$
