Answer:   \frac{12ch}{a}

This is the same as writing (12ch)/a

===================================================

Explanation:

When multiplying fractions, we multiply the numerators together separately from the denominators.

\frac{21c^2}{a}\times \frac{4h}{7c} = \frac{21c^2*4h}{a* 7c}

Then notice the 21 over 7 reduces to 3.

Also, simplifying the c^2 over c part leads to c

Nothing else cancels.

We're left with this: \frac{3c*4h}{a} = \frac{12ch}{a}

What is the standard form of the equation of a parabola is y = 5x^2 + 20x + 14. What is the vertex form of the equation
Y_Kistochka [10]

vertex form is y=a(x-h)^2+k

comlpete the square

y=5x^2+20x+14

group x terms

y=(5x^2+20x)+14

factor quadratic coefient

y=5(x^2+4x)+14

take 1/2 of linear coefient and square it

4/2=2, 2^2=4

add positive and negative of it inside the parentheasees

y=5(x^2+4x+4-4)+14

factor perfect squarer trinomial

y=5((x+2)^2-4)+14

expand

y=5(x+2)^2-20+14

y=5(x+2)^2-6 is vertex form

True [87]

Answer:

6.27

Step-by-step explanation:

We are to obtain the standard deviation of the given values :

{24, 18, 31,25, 34}

The standard deviation = √(Σ(x - mean)²/ n)

The mean = (ΣX) /n

Using calculator to save computation time :

The standard deviation, s = 6.27 (2 decimal places)

What is the radius of a cylinder with a volume of 3,165.12 cubic centimeters and a height of 7 centimeters?
leonid [27]

Answer:

Radius = 12 cm

Step-by-step explanation:

Given:

Volume of the cylinder is, V=3165.12 cm³

Height of the cylinder, h= 7 cm

Let the radius be r

Using the formula for volume of cylinder,

V=\pi r^2h

Plug in 3165.12 for V, 7 for h and solve for r.

3165.12=\pi r^2(7)\\3165.12=\frac{22}{7}\times 7\times r^2\\3165.12=22r^2\\r^2=\frac{3165.12}{22}\\r^2=143.869\\r=\sqrt{143.869}=11.99\approx=12\textrm{ cm}

Therefore, the radius of the cylinder is nearly 12 cm.
