Answer:

0.0267m/s

Step-by-step explanation:

Given the following

Length of the wave = 10cm  = 0.1m

Time taken = 3.75seconds

Required

Wave speed in m/s

Speed = Distance/Time

Substitute the given values into the formula

Speed = 0.1/3.75

Speed = 0.0267m/s

Hence the speed of the wave in m/s is 0.0267m/s

Answer: 0.0267m/s

Step-by-step explanation: Hence the speed of the wave in m/s is 0.0267m/s because the Length of the wave = 10cm  = 0.1m

Wave speed in m/s

Speed = Distance/Time

Substitute the given values into the formula

Speed = 0.1/3.75

Speed = 0.0267m/s

The quadratic function f(x) = -2(x + 4)^2 - 5 in standard form is:

f(x) = -2x² - 16x - 37.

A function has an input and an output.

A function can be one-to-one or onto one.

It simply indicated the relationships between the input and the output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

To rename the quadratic function f(x) = -2(x + 4)^2 - 5 in standard form, we need to expand and simplify the expression:

f(x) = -2(x + 4)² - 5

f(x) = -2(x² + 8x + 16) - 5

f(x) = -2x² - 16x - 32 - 5

f(x) = -2x² - 16x - 37

Therefore,

The quadratic function f(x) = -2(x + 4)^2 - 5 in standard form is:

f(x) = -2x² - 16x - 37.

Answer:

4 23/40

Explanation:

Answer:

Second Option, 4 23/40

Step-by-step explanation:

7 3/8 = 59/8

2 4/5 = 14/5

14 x 8 = 112

5 x 8 = 40

112/40

59 x 5 = 295

8 x 5 = 40

295/40

295 - 112 = 183

183/40 = 4 23/40

Answer: D. (x, y) --> (y, -x)

Step-by-step explanation:

The rule for a 90° clockwise rotation about the origin results in a transformation as : (x, y) --> (y, -x)

The rule for a 90° counterclockwise rotation about the origin results in a transformation as : (x, y) --> (-y, x)

For 180° rotation abiut the origin : (x, y) --> (-x, - y)

For 270°:

clockwise rotation : (x, y) --> (-y, x)

Counterclockwise rotation : (x, y) --> (y, -x)

Step-by-step explanation:

h(t) = -16t² + 16t + 12

h(t) = -4(4t² - 4t - 3)

h(t) = -4(2t - 3)(2t + 1)

When h(t) = 0, we have t = 1.5 or t = -0.5.

Hence the zeroes are 1.5 and -0.5.

Answer: a(n) = 5 - 3n

the sequence has:

a1 = 2

a2 = -1

a3 = -7

.........

we can see that: a2 - a1 = a3 - a2 = -3

=> the sequence is a  arithmetic sequence

=> the distance between the numbers is d = -3

because this sequence is a  arithmetic sequence

=> a(n) = a1 + (n - 1)d = 2 + (n - 1).(-3) = 5 - 3n

Step-by-step explanation:

Answer

n = 30

Explanation

To solve for n, you have to isolate it by 'getting rid' of the 18, 2, and negative sign.

You 'remove' these numbers in backward PEMDAS.

So to 'remove' the 18, you subtract both sides by 18.

3-18 = -15

-n/2+18-18 = -n/2

So now you are left with -15 = -n/2.

To 'get rid' of the 2, you multiply each side by 2.

-15×2 = -30

-n/2×2 = -n

And now you have -30 = -n.

To 'get rid' of the negative sign, you multiply both sides by -1.

-30×-1 = 30

-n×-1 = n

So you get 30 = n or n = 30.

Answer: x = 2

Step-by-step explanation:

The rule for reflecting over  x = 2 is that y remains the same and you add how many units x = 2 is from the point.

x = 2 is has the coordinate of x = 2 and y = the y coordinate of the point.

A (-1, 1) Since the y coordinate of (-1, 1) is 1, x = 2 - (2, 1)

Add 3 units to 2, the x coordinate since -1, 1 is 3 units from 2, 1

2,1 --> 5, 1

Step-by-step explanation:

Given

[tex]Y : B = 3 ; 2[/tex]

Required

Find the  number of blue paints in 12 gallons

Start by representing the blue part of the ratio as a fraction

[tex]Y : B = 3 ; 2[/tex]

[tex]B = \frac{2}{2 + 3}[/tex]

[tex]B = \frac{2}{5}[/tex]

This means that:

[tex]Blue = \frac{2}{5} * 12\ Gallons[/tex]

[tex]Blue = \frac{24}{5} \ Gallons[/tex]

[tex]Blue = 4.8 \ Gallons[/tex]
