Lady bird [3.3K]3 years ago

A couple of rules to review:

#1).         Ln(the square root of a number) = 1/2 Ln(the number)
and
#2).         e^(Ln of a number)  =  the number

Now we're all set to solve this thing.
=======================================

            <u>Ln(  square root of(x+2)  )  = 3</u>

From Rule #1:             1/2 Ln (x+2)   =   3

Multiply each side by 2:       Ln (x+2) = 6 

From Rule #2:                        (x + 2) = e^6

                                             (x + 2)  =  403.43  (rounded)

Subtract  2  from each side:       <em>  x  =  401.43</em>  (rounded)

A rectange has a width of 9 units and a length of 40 unit. what is the length in diagonal
AlekseyPX

Answer:

41 units

Step-by-step explanation:

The diagonal forms a right triangle with the sides, so we can use Pythagorean theorem.

c² = a² + b²

d² = 9² + 40²

d = 41

The diagonal is 41 units long.

The estimated velocity v (in miles per hour) of a car at the end of a drag race is v=234 3√p/w (cube root) , where p is the hors
faltersainse [42]
Given that <span>v=234 3√p/w (cube root)
where </span><span> 
p is the horsepower of the car and
w is the weight (in pounds) of the car
v is the velocity in miles per hour

p = 1311 hp
w = 2744 lb
substitute the given value to the equation to solve for the velocity

v = 234 </span><span>3√(1311 / 2744)
v = 183 miles per hour is the velocity of a car at the end of a drag race.</span>

Instructions: Use the ratio of a 30-60-90 triangle to solve for the variables.
Pepsi [2]

Answer:

x=20

y=10\,\sqrt{3}

Step-by-step explanation:

In the triangle we have the following trigonometric equations:

tan(60^o)=\frac{opposite}{adjacent} \\\sqrt{3} =\frac{y}{10} \\y=10\,\sqrt{3}

and also:

cos(60^o)=\frac{adjacent}{hypotenuse}\\\frac{1}{2} =\frac{10}{x}\\x=20

Answer:

Step-by-step explanation:

hello :

f(x) = 2x +1 and g(x) = x².

(gºf)(a)= g(f(a)) = g(2a+1) = (2a+1)² = 4a²+4a+1
