Answer:

<h2>r = 7.27</h2>

Step-by-step explanation:

Opposite = r\\Hypotenuse = 13\\\alpha = 34\\Using SOHCAHTOA\\Sin \alpha = \frac{opp}{hyp} \\Sin 34 = \frac{r}{13} \\0.559 = \frac{r}{13} \\Cross \: Multiply\\r = 0.559\times 13\\r = 7.267\\r = 7.27

Answer:

$137,339.88

Step-by-step explanation:

Here is the equation for compound interest: A=P(1+(r/n))^nt

where A=amount of money, P=principal, r= rate in decimal, n=number of times compounded per t, and t=time

In this case:

A=$250,000

P= ?

r= 0.04

n= 12 month/yr

t= 15 yrs

You can manipulate the equation to solve for P:

P=A/[(1+(r/n))^nt]

Plug in variables then solve:

P= \frac{250,000}{(1+\frac{0.04}{12})^{12*15} }

P=137339.8761 = $137,339.88

Answer:

0.25m or 1/4m

Step-by-step explanation:

Given Height of Dorsal Fin = 1/6 of Length of whale Sculpture,

and given length of whale sculpture = 1.5m or 1\frac{1}{2} m\\

Height of Dorsal fin on scuplture = (\frac{1}{6})(1\frac{1}{2} )\\

= (\frac{1}{6} )(\frac{3}{2}) \\= \frac{3}{12} \\= \frac{1}{4}m or 0.25m

Write the slope-intercept form of the equation of each line 13x-2y=14
HACTEHA [7]

Answer:

Step-by-step explanation:

First, lets put this into y=mx+b form.

You can bring the 13x over to the 14, by subtracting and you get -2y=14-13x, or also -2y = -13x + 14

Then you can divide both sides by -2 to get y, and you get

-2y/-2 = -13x/-2 + 14/-2 which is simplified to y=13/2x + (-7) which is

y=13/2x-7

                                {[( IMPORTANT )]}

 THIS HAS THE SLOPE IN A IMPROPER FRACTION... CHECK IF YOU USE MIXED NUMBERS OR IMPROPER FRACTIONS

the mixed number form is y = 7     1/2 x -7

Hope this helps!
