4 0

Answer:

y=-x-7

Step-by-step explanation:

Equation of straight line in point slope form is given as

y-y_1=m(x-x_1)

Here

m=-1 \ and \ (x_1, y_1)=(-2, -5)

Therefore,

y+5=-1(x+2)

y=-x-7

The perimeter of a semicircle is 81.212 yards. what is the semicircle's diameter?
adoni [48]

\textit{circumference of a semicircle}\\\\ C=\pi r ~~ \begin{cases} r=radius\\[-0.5em] \hrulefill\\ C=81.212 \end{cases}\implies 81.212=\pi r\implies \cfrac{81.212}{\pi }=r \\\\\\ \stackrel{\textit{its diameter is}}{2r\implies 2\left( \cfrac{81.212}{\pi } \right)} ~~ \approx ~~ 51.7

Use forward or backward substitute to conjecture a closed formula which describes the nth term of the sequence an = an-1 – n, wh
WINSTONCH [101]
The closed formula for  <span>an = an-1 – n will be found using the formula for arithmetic sequence given by:
an=a+d(n-1)
where
a=first term
d=common difference
n=number of terms
From the formula given:
a=4
d=n
thus the formula will be:
an=a+n(n-1)
an=4+n(n-1)

There are 10 pieces of fruit in a fruit bowl. There are x bananas in the fruit bowl. All of the rest of the fruit are apples.
-BARSIC- [3]

The probability that Sarah takes one piece of each fruit is; (10x - x²)/100

<h3>Probability</h3>

We are given;

  • Number of fruits in the bowl = 10
  • Number of bananas = x

Thus, remaining fruits are;

  • Number of apples = 10 - x

Probability that at least one will be banana = x/10

Probability that at least one will be apple = (10 - x)/10

Thus;

Probability that she takes one piece of each fruit is;

x/10 × (10 - x)/10

⇒ x(10 - x)/100

⇒ (10x - x²)/100

What is a closed line of credit
Vinvika [58]

You may start out with a "line of credit" agreement with a bank that allows you to create relatively small loans by the bank to yourself at a specified interest rate and under other specific terms. Of course you must repay these loans, with interest, and that's how the bank makes its money.

If you fail to repay the bank, the bank may close your account and demand that you immediately repay all the money you owe it. A "closed line of credit" is a pretty sad thing.
