The volume of the figure is 9ft 15ft 15ft 15ft please help fast PLEASE!

Whitepunk [10]

Step-by-step explanation:

Formulas.

Square: $V = L \times W \times H$

Square Pyramid: $V = \frac13b^2h$

b = base.

Let's work on the square first.

Substitute the Length, Width, and Height of the square into the formula:

$V=15 \times15\times15$

Solve:

$V=15^{3} =3,375$

Let's work on the square pyramid.

Substitute 225 into the formula, and 9 (height):

$V=\frac{1}{3}(15)^2(9)$

Solve:

$V=\frac{1}{3}225(9)$

$V=\frac{1}{3}(2025)$

$V=675$

Add each volume:

$3,375+675=4,050 ft^{3}$

The total volume of the figure is $4,050 ft^{3}$ .

If sin square theta = 0.75, then cos =

sergeinik [125]

Answer:

$\cos\theta=\pm0.5$

Step-by-step explanation:

Given:

$\sin^2\theta=0.75$

To find $\cos\theta$

Using trigonometric relations for sums and differences of squares of the ratios.

We know:

$\sin^2\theta+\cos^2\theta =1$

Plugging in $\sin^2\theta=0.75$ in the above relation.

$0.75+\cos^2\theta =1$

Subtracting both sides by 0.75.

$0.75+\cos^2\theta-0.75 =1-0.75$

$\cos^2\theta =0.25$

Taking square root both sides.

$\sqrt{\cos^2\theta} =\sqrt{0.25}$

∴ $\cos\theta=\pm0.5$ (Answer)
