The answer to this question is Y= -1/3 - 2

The equation is y = -1/3x-2.

To determine the equation, I remembered that for a equation to be perpendicular of another, the original slope will be the reciprocal. So, -3 will turn into -1/3. Then I written the equation y=mx + b. I wrote out -4 = -1/3 (6) + b because I plugged in the x and y values. Then I solved for b. The result I got for b was -2.

After solving for b, the equation I found was y= -1/3x-2

Answer:

tn = 2097152 pennies
tn = 20971.52 dollars.

Step-by-step explanation:

A surprisingly large amount of money.

The question is "Does the amount of money just double or do the previous amounts add to the present amount?"

I think it just doubles. Not only that, but she can't spend any of it until night 22 is reached.

tn = a*2^(n - 1)
a = 1 She starts with 1 penny.
n = 22
tn = 1*2^(22 - 1)
tn = 1*2^21
tn = 2097152 pennies
tn = 20971.52 dollars.

In History, you earned an exam score of X-85 where the exam average was μ-65 with a standard deviation of σ-5. In Biology, you e

Answer: D. History

Step-by-step explanation:

To answer this question, we need to use the z-score formula written below:

$\frac{x-pop. mean}{stan. devi.}$

Now we'll just plug in the numbers and solve.

History:

$\frac{85-65}{5} = 4$

Biology:

$\frac{90-85}{10} =0.5$

As we can see, history wields a higher z-score than biology, thus leaving us with option D. History

How do I work out this problem?

cluponka [151]

First we need to find ∡PRQ. To do this we can use the fact that the sum of the interior angles of a triangle is 180°:

$180=R+P+Q$
$180=R+40+105$
$180=R+145$
$R=180-145$
$R=35$

Now, we can use the fact that a strait line (like SRQ) is also 180°:
$SRQ=180-R$
$SRQ=180-35$
$SRQ=145$ °
