Find geometric mean between 3 and 6

Answers

Answer 1

Answer: $geometric\ mean\ between \ a\ and\ b\ = √(a\cdot b) \n----------------------\n\ngeometric\ mean= √(3\cdot6) = √(3\cdot3\cdot2) =3\cdot √(2)$

Answer 2

Answer: Call the geometric mean ' G '.

Then (3 / G) = (G / 6)

This is a proportion, and may be "cross-multiplied":

G² = 18

G = √18 = about 4.2426... (rounded)

What is the perimeter of the triangle expressed as a polynomial? Length: 8x-2
Length: 5x-4
Width: 9x-3
If you could show me how you got the complete answer I would really appreciate it.

Answers

The perimeter is the sum of the lengths of the three sides of the triangle. If "width" is the length of the 3rd side, then the perimeter is
P = (8x-2) + (5x-4) + (9x-3)
P = 8x + 5x + 9x -2 -4 -3
P = (8+5+9)x -(2+4+3)
P = 22x - 9

What are the values of the coefficients and constant term of 0 = 4 – 7x2 + x in standard form?a =
b =
c =

Answers

By definition, the standard parabola equation is given by:
$ax ^ 2 + bx + c = 0$
We then have the following quadratic equation:
$0 = 4 - 7x ^ 2 + x$
By rewriting the equation in its standard form, we have:
$- 7x ^ 2 + x + 4 = 0$
Comparing with the definition, we have that the values of the coefficients are given by:
$a = -7 b = 1 c = 4$
Answer:
The values of a, b and c are given by:
$a = -7 b = 1 c = 4$

Answer

a = -7 × 10⁰

b = 1 × 10⁰

c = 4 × 10⁰

Explanation

The general formula is; ax² + bx + c.

Where a ⇒ co-efficient of x²

b ⇒ co-efficient of x

c ⇒ The constant term

0 = 4 – 7x² + x This equation can be written in the form of ax² + bx + c.

0 = 4 – 7x² + x = -7x² + x + 4 = 0

Comparing the values of a, b and c in the equation in standard form are;

a = -7 × 10⁰

b = 1 × 10⁰ and

c = 4 × 10⁰

10 over 7 x 3 over 8

Answers

When you multiple fractions, you just multiple numerators and denominators.

10 / 7 × 3 / 8 = (10 × 3) / (7×8) = 30 / 56

Now reduce the fraction:

30 / 56 = 15/28

Final answer: 15/28

Depth d (in feet) of a river can be modeled by the equation d=−0.25t2+1.7t+3.5, where 0≤t≤7 and t is the time (in hours) after a heavy rain begins. When is the river 6 feet deep?

Answers

Answer:

The river is 6 feet at two times, 2.15 hours after the rain and 4.65 hours after the rain.

Step-by-step explanation:

We are given the following in the question:

$d=-0.25t^2+1.7t+3.5$

$0\leq t\leq 7$

where, d is the depth of river in feet and t is time in hours after a heavy rain.

We have to find the number of hours for which the depth of river is 6 feet.

Putting d = 6 in the equation, we get,

$6=-0.25t^2+1.7t+3.5\n\Rightarrow +0.25t^2-1.7t+2.5 = 0\n\text{Using quadratic formula}\n\n\Rightarrow t = (1.7\pm √((-1.7)^2-4(0.25)(2.5)))/(2(0.25))\n\nt\approx 4.65, 2.15$

Thus, the river is 6 feet at two times, 2.115 hours after the rain and 4.65 hours after the rain.
