Answer: Flying disc

Step-by-step explanation:

Hi, to answer this question we have to apply the next formula for each object:

Circumference(C) = π x diameter

Coin

Diameter = 3

Circumference (measured) = 10

C (calculated) = π x d = π x 3 = 9.42

10≅9.42

Flying disc

Diameter =23

Circumference (measured) = 28

C (calculated) = π x d = π x 23 = 72.25

72.25 ≠ 28

Not accurate

Jar lid

Diameter =8

Circumference (measured) =25

C (calculated) = π x d = π x 8= 25.13

25 ≠ 25.13

Flower pot

Diameter =15

Circumference (measured)=47

C (calculated) = π x d = π x 15 = 47.12

47 ≠47.12

Feel free to ask for more if needed or if you did not understand something.

Find the equation of the line passing through the points (3,7) and (-2,5)

r-ruslan [8.4K]

Answer:

The equation of the line passing through the points (3,7) and (-2,5) is y=⅖x+29/5

Step-by-step explanation:

Greetings !

$first \: find \: the \: slope \: m \\ m = \frac{(Y₂-Y₁)}{(X₂-X₁)} ..substitute \: vlues \\ m = \frac{(5 - 7)}{( - 2 - 3)} = \frac{ - 2}{ - 5} = \frac{2}{5} \\ y = mx + b \: to \: find \: equation \: of \: aline \\ between \: two \: poins and \: use \: \\ one \: of \: the \: two \: points \: lets \: take( - 2.5) \\ y = mx + b \\ 5 = \frac{ - 2}{5} ( - 2) + b \\ 5 = \frac{ - 4}{5} + b \\ 5 + { - 4}^{5} = b \\ \frac{25 + 4}{5} = b \\ b = \frac{29}{5} \\ finally \: equation \: of \: the \: line \: will \: be \\ y = \frac{2}{5} x + \frac{29}{5}$

Which is the graph of y= cos(x-pi)

marshall27 [118]

Answer:

graph attached

Step-by-step explanation:

A graph is a pictorial representation that represent the relationship between two or more things.

Cosine function is periodic with period $2\pi$ . If the point $(x,y)$ lies on the graph, point $(x+2k\pi ,y)$ will also lie on the graph where k is any integer.
