Prism A and prism B are similar with a ratio of similarity of 2:3. If the volume of prism A is 36 cubic units, what is the volum

e of prism B?

Ratio of their
x = 27*36 / 8 volumes = 2^3 : 3^3 or 8:27

so 8/27 = 36/x

x = 27*36 / 8 = 121.8 cubic units

How to round in math im confused

Nastasia [14]

If the number you are rounding is 5, 6, 7, 8, or 9, it goes to ten. If the numbers are 4, 3, 2, or 1, then round down. For example,, 37 is rounded to 40. 34 is rounded to 30.

Help with those three please!!

Scilla [17]

Answer:

Part 1) Option A. The axis of symmetry is x=4

Part 2) Option C. minimum

Part 3) Option A. (4,-4)

Part 4) Option B. (2,0) and (6,0)

Step-by-step explanation:

we have

$f(x)=x^{2}-8x+12$

Part 1) What is the axis of symmetry of the parabola described by the equation above?

we know that

The equation above is a vertical parabola open upward

The axis of symmetry is the x-coordinate of the vertex

Find the vertex of the parabola (convert the equation in vertex form)

$f(x)-12=x^{2}-8x$

$f(x)-12+16=x^{2}-8x+16$

$f(x)+4=x^{2}-8x+16$

$f(x)+4=(x-4)^{2}$

$f(x)=(x-4)^{2}-4$ ----> equation in vertex form

The vertex of the parabola is (4,-4)

so

The axis of symmetry is x=4

Part 2) The vertex of the equation above is also

we know that

The equation above is a vertical parabola open upward

therefore

The vertex is a minimum

Part 3) What is the vertex of the parabola described by the equation above

we know that

The equation of the parabola into vertex form is equal to

$f(x)=(x-4)^{2}-4$

therefore

The vertex of the parabola is (4,-4)

Part 4) What are the x-intercepts of the parabola described by the equation above

we know that

The x-intercepts are the values of x when the value of y is equal to zero

so

$f(x)+4=(x-4)^{2}$

f)x)=0

so

$4=(x-4)^{2}$

take square root both sides

$(x-4)=(+/-)2$

$x=4(+/-)2$

$x=4(+)2=6$

$x=4(-)2=2$

therefore

The x-intercepts are

(2,0) and (6,0)

Yezenia is filling up her outdoor swimming pool to get ready for summer time. She leaves the garden hose running for 1000 minute

Charra [1.4K]

Answer:

15.46 gallons per minutes

Step-by-step explanation:

Garden hose was running for 1000 minutes

Volume of the pool = 15,460 gallons

What is the approximate rate at which water leaves the garden hose?

Rate at which water leaves the garden hose = Volume of the pool / running time of the hose

= 15,460 gallons / 1000 minutes

= 15.46 gallons per minutes

Rate at which water leaves the garden hose = 15.46 gallons per minutes

Quicklkkkkkkkk If a football player passes a football from 4 feet off the ground with an initial velocity of 36 feet per second,

son4ous [18]

Answer:

Since time can't be negative, the only possible solution is 0.72 s.

Step-by-step explanation:

When the ball hits the ground its height is equal to 0, so we must find a value for "t" that results in h = 0. We have:

$-16*t^2 + 6*t + 4 = 0\\t_{1,2} = \frac{-6 \pm \sqrt{(6)^2 - 4*(-16)*(4)}}{2*(-16)}\\t_{1,2} = \frac{-6 \pm \sqrt{292}}{-32}\\t_{1,2} = \frac{-6 \pm 17.1}{-32}\\t_1 = \frac{-6 -17.1}{-32} = 0.72\\t_2 = \frac{-6 + 17.1}{-32} = -0.35\\$

Since time can't be negative, the only possible solution is 0.72 s.
