Radda [10]

Each birdhouse uses 12 sq ft of wood.

He has enough to build 10 birdhouses, so he has 120 sq ft of wood.

The function has an input of the number of birdhouses, b, and has an output of the amount of wood needed, W. b is the input or the domain, and W is the output or the range. The domain is 0 to 10. The range is 0 to 120.

Answer:  B. D: 0 ≤ b ≤ 10 R: 0 ≤ W(b) ≤ 120 

Enjoy! Hope this helped you! :)

I need help the questions says to find ths y intercept aftet the line transforms 3 units down
Ganezh [65]
That's easy

the y intercept is where it hits the y axis
that is how far up or down
so then it tells you to transform it 3 units down
just find the y intercept then minus 3 from it


ok
y intercept is where line crosses y axis or where x=0

so set x=0 and solve for y

6(0)+5y=-15
0+5y=-15
5y=-15
y=3 is the y intercept

translate 3 units down so
3-3=0
y=0 is the y intercept after transformation (should be translation)

A bucket of water is swung in a circle in a vertical plane. The radius of the circle is 0.85 m. What is the minimum speed that w
s344n2d4d5 [400]

Answer:2.88 m/s

Step-by-step explanation:

Given

radius of circle r=0.85 m

At highest Point weight will Provide the centripetal Force

thus

weight=mg

Centripetal\ Force=\frac{mv^2}{r}

where m is the mass of water in bucket

mg=\frac{mv^2}{r}

v=\sqrt{gr}

v=\sqrt{9.8\times 0.85}

v=2.88 m/s
