Answer:

2 \div 3 \times 5 \div 6 \:  = 10 \div 18

We just have to multiply not cross multiply,

10/18

Now, divide the equation

5/9 will be ur answer

Answer:

No

Step-by-step explanation:

\frac{2}{3}   \frac{5}{6}

2 goes into 6 3 times so it would be the same as 1 going into 3 3 times.

\frac{1}{3}  \frac{5}{3}

Since 3 doesn't go into 5 at all (and by that I mean a whole number) you don't change it.

Multiplying 1/3 and 5/3, you would get 5/9.

Multiplying 2/3 and 5/6, you would get 10/18, which simplifies to 5/9.

That is kind of how cross multiplying works.

The equation of the sinusoidal function is y = -2sin(x + 1.5) - 3

<h3>The sinusoidal function</h3>

The minimum and the maximum of the function are

  • Minimum = -1
  • Maximum = -5

The amplitude (A) is calculated as:

A = 0.5 * (Maximum - Minimum)

So, we have:

A = 0.5 * (-5 + 1)

A = -2

The vertical shift (d) is calculated as:

d = 0.5 * (Maximum + Minimum)

So, we have:

d = 0.5 * (-5 - 1)

d = -3

The period (P) is calculated as:

P = 2π/B

From the graph,

B = 1

So, we have:

P = 2π/1

P = 2π

So, the amplitude is -2 and the period is 2π.

<h3>The equation of the sine function</h3>

In (a), we have:

A = -2

B = 1

d = -3

A sine function is represented as:

y = A sin(Bx + C) + D

So, we have:

y = -2sin(x + C) - 3

The graph passes through the point (0, -5)

So, we have

-5 = -2sin(0 + C) - 3

Solve for C, we have

C = 1.5

So, we have:

y = -2sin(x + 1.5) - 3

Hence, the equation of the sinusoidal function is y = -2sin(x + 1.5) - 3

Explain how to apply the substitution property of equality to the equation
Vlad1618 [11]

Answer: Substitute the values given. The equation is a + 42 = b. Since a = -16 and b = 26, the equation will become -16 + 42 = 26. This equation holds true so it is correct.

Answer:

=14.92...

14 the maximum number of spheres that Daniel can make from the chunk of clay.

.

Step-by-step explanation:

10^3=1000 in^3

1000/2=500 vol of one congruent chunk.

4/3 * pi * r^3 = vol of a sphere

500/(4/3 * pi * 2^3)

=14.92...
