Answer:

Line segment TS.

Step-by-step explanation:

We have an Unit Circle. The y-coordinate of T is the sine of $\theta$ . Therefore, the exact value of $\text{sin}(\theta)$ is TS.

$T(\text{cos}(\theta),\text{sin}(\theta))$

Help with volume all help is appreciated :)

Lina20 [59]

Answer:

It would be 0.41 ft^3

Step-by-step explanation:

Alright, to start, lets get the volume of the entire cinder block and the holes within it.

1.31 * 0.66 * 0.66 ---> 0.5706...

Next with the holes, they are both 0.33 wide, 0.39 long, and just as tall at 0.66 feet.

0.33 * 0.39 * 0.66 ---> 0.0849...

Since there's two of them: 0.1698...

To finish it, subtract the hole volume from the total volume;

0.5806 - 0.1698 = 0.4108

Rounds to 0.41 ft^3

The base of a triangle is nine centimeters longer than the perpendicular height. If the area of the triangle is 180 square centi

Rom4ik [11]

Answer:

The base is 24 cm long.

Step-by-step explanation:

Equations

Let's call

b= base of the triangle

h=height of the triangle

The base is 9 cm longer than the height, thus:

b = h + 9

The area of the triangle is:

$\displaystyle A=\frac{bh}{2}$

$\displaystyle A=\frac{(h+9)h}{2}$

And its value is 180:

$\displaystyle \frac{(h+9)h}{2}=180$

Multiplying by 2:

$(h+9)h=360$

Operating:

$h^2+9h-360=0$

Factoring:

$(h-15)(h+24)=0$

The only valid positive solution is:

h = 15 cm

And b = h + 9 = 24

b = 24 cm

The base is 24 cm long.

The intensity of light bulb measured in watts per square meter (w/m^2), varies inversely as the square of the distance d from th

krek1111 [17]

Answer:

I(7) = 22.96 W/m²

Step-by-step explanation:

Let intensity of light, be I(d) where d is distance. There must be a proportionality factor K such as

I(d) = K /d²

Now for d = 5 m I(d) = K* 1/d²

then 45 * 25 = K

K = 1125

To find the intensity when the distance from the light bulb is 7 m away

I(7) = K / 49

I(7) = 1125/49 W/m²

I(7) = 22.96 W/m²
