Anya found the slope of the line that passes through the points (–7, 4) and (2, –3). Her work is shown below. Let (x2, y2) be (–

7, 4) and (x1, y1) be (2, –3). m = x2-x1/y2-y1 = -7-2/4-(-3)= -9/7 The slope is -9/7 What error did she make?

M=y2-y1/x2-x1 not x2-x1/y2-y1, that is her error

Step-by-step explanation:

The points (-7, 4) and (2, -3) through which line is passing.

The equation of line passing two point is given as:(x_1,y_1)(x_2,y_2)

(y-y_1)=\frac{(y_2-y_1)}{(x_2-x_1)}\times (x-x_1)

(y-y_1)=m\times (x-x_1)

m = slope of the line

The equation of the line will be:

(y-4)=\frac{(-3-(4))}{(2-(-7))}\times (x-(-7))

(y-4)=\frac{-7}{9}\times (x+7)

Slope of the line = m=\frac{-7}{9}

The error made by the Anya was that she has used wrong formula.

m = \frac{x_2-x_1}{y_2-y_1} (Wrong formula)

Megan has a piece of fabric which is a right triangular shape. The length of leg 1 is 4 m. The length of the other leg is twice
Bess [88]

Answer:

8.94 m

Step-by-step explanation:

Use the Pythagorean Theorum - a^2 + b^2 = c^2. Use leg 1 as <em>a</em>, leg 2 as <em>b</em>, and the third side as <em>c</em>.

We know leg 1 is 4, and that leg 2 is twice as long as leg 1...

(4)^2 + (4*2)^2 = c^2

Now, we use the Order of Operations to find c^2...

4^2+8^2=c^2\\16+64=c^2\\80=c^2

Now, we find the square root of c^2 to find c...

\sqrt{80} =8.94

So, the length of the third side is 8.94 m.

A restaurant manager collected data on the number of customers in a party in the restaurant and the time elapsed until the party
Stella [2.4K]

Answer:

Option C The parties with a larger number of customers are associated with the longer times elapsed until the party left the restaurant.

Step-by-step explanation:

The correlation coefficient 0.78 shows that positive association between two variables number of customers and elapsed time until party left restaurant.

The positive association means that as the number of customers in a party increases the elapsed time also increase. So, we can say that the parties with a larger number of customers are associated with the longer times elapsed until the party left the restaurant.

PLEASE ANSWER WILL GIVE POINTS!!!!!!!!!!!!!
Gennadij [26K]

Answer:

1) 27.374

2)9.177

Step-by-step explanation:

1) To get the value of x , we use the appropriate trigonometric ratio

From what we are given;

we have the hypotenuse ( the side facing the right angle) and the adjacent

The trigonometric identity to use here is the cos

The cos of an angle is the ratio of the adjacent to the hypotenuse

cos 64 = 12/x

x = 12/cos 64

x = 27.374

2) Here, we are given the hypotenuse and the opposite

The trigonometric ratio to use here is the sine

the sine of an angle is the ratio of the opposite to the hypotenuse

thus, we have it that;

sin 35 = x/16

x = 16 sin 35

x = 9.177
