Determine the amplitude or Period as requested. Period of y= -2 sin x

Alex Ar [27]

amplitude: 2

period: 2pi

The equation for a sin function is:

$y = a \sin(b(x - c) ) + d$

a = the amplitude

b = the period

c = the horizontal shift

d = the vertical shift

the equation to find the period of a sin function is:

$period = \frac{2\pi}{b}$

note: the amplitude is always a positive number, if there is a negative sign in front of it then that means it reflects over the x-axis.

I need help with 9,11,12, and 13

Alex_Xolod [135]

#9
since LJ = LK + KJ, replace the letters with the corresponding equations. You'd get:
LJ = (7x-10) + 28
LJ = 7x + 18
Do you need an integer or is that okay?^

ETHANHUNT HELP PLS The marked sides have equal lengths. What is the value of x?

dezoksy [38]

Here, both sides are equal, represented by - sign.
So, 4x + 12 = 60
4x = 60 - 12
x = 48/4
x = 12

In short, Your Answer would be 12

Hope this helps!

#1) Mrs. Ebanks planted two trees on a

uranmaximum [27]

Answer:

D = 12.94 m

Step-by-step explanation:

Coordinates of first tree = A(0,8)

Coordinates of second tree = A(12,4)

We need to find the distance between the two trees. We can find it using distance formula for coordinates as follows :

$D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

We have, x₁ = 0, x₂ = 12, y₁ = 8, y₂ = 4

Now using distance formula,

$D=\sqrt{(12-0)^2+(4-8)^2}\\\\=\sqrt{144+16} \\\\=12.64\ m$

So, the distance between the two trees is 12.64 m.
