Answer:

55.4 in³

Step-by-step explanation:

The formula for the volume of a pyramid can be found:

V = \frac{1}{3}Bh, where B = area of the base and h = height of the pyramid

Since the base is a triangle, we need to use the formula for the area of a triangle:

A = \frac{1}{2}bh = \frac{1}{2}(5.7)(6.2)=17.67in^{2}

Next, multiply the area of the base by the height of the pyramid:

17.67 x 9.4 = 166.098 ÷ 3 ≈ 55.4 in³

shutvik [7]

Answer:

Equation of movement y(t)

y(t)=sin(10t-\pi/2)

Amplitude: 1 inch

Period: 0.628 seconds

Step-by-step explanation:

If there is no friction, the amplitude will be the length it was streched from the equilibrium. In this case, this value is 1 inch

A=1\,inch

The period depends on the mass and the spring constant.

The formula for the period is:

T=\frac{1}{f} =\frac{2/pi}{\omega} =2\pi\sqrt{\frac{m}{k}}=2\pi\sqrt{\frac{1}{100}}=2\pi*0.1=0.628\, s

The model y(t) for the movement of the mass-spring system is

y(t)=A\cdot sin(\omega t +\phi)\\\\A=1\\\\\omega=\sqrt{k/m} =\sqrt{100/1}=10\\\\y(0)=Asin(\phi)=-A\\\\ \phi=arcsin(-1)=-1.571=-\pi/2\\\\\\y(t)=sin(10t-\pi/2)

Answer:

A

Total before tax: $118

Total after tax: $102.66

Step-by-step explanation:

For A, we add the cost of the shirt and jeans to get the total before tax.

$39.20 + $79.80 = $118.00

For the total, after 13% we see how much 1% is.

1% of $118 is $1.18

$1.18 * 13 = $15.34.

$118 - $15.34 = $102.66

Hope this helped! Have a nice day :)
