Answer:

4xy exponent 7/2xy exponent 6

Zinaida [17]3 years ago

Answer:

Step-by-step explanation:

First expand the numerator by distributing in the 2 outside the parenthesis to get

\frac{16x^6y^4}{2x^6y} and now, working on one thing at a time, we will divide:

<u>16     x⁶     y⁴</u>

2      x⁶      y    

I separated each set of like expressions to make it easier to see. First divide the numbers, 16 by 2:

<u>8       x⁶      y⁴</u>

        x⁶      y

the x's cancel out (divide to a 1):

<u>8      y⁴</u>

       y

and by the rules for dividing like bases, we will subtract the exponents, lower from upper to get, finally:

8y³

Answer:

base = 18.89

legs = 16.89

Step-by-step explanation:

x + x + 68 = 180

2x + 68 = 180

2x = 112

x = 56

The altitude = 14

Tan(56) = opposite / adjacent

adjacent = base

opposite = altitude

Tan(56) = opposite / base                Multiply both sides by the base

base * Tan(56) = opposite                Divide by Tan(56)

base = opposite / Tan(56)

base = 14/tan(56)

base = 9.443

The base is actually twice this length because the altitude lands on the midpoint of the opposite side and is perpendicular to the third side (base).

base = 18.886  

Legs are the hypotenuse formed by 1/2 the base and the attitude.

Sin(56) = opposite / hypotenuse

Sin(56) = altitude / hypotenuse

hypotenuse = altitude / Sin(56)

hypotenuse = 14 / sin(56)

hypotenuse = 16.887

Rounded

base = 18.89

legs = 16.89

What is the result of isolating x^2 in the equation below 10x^2-36y^2=100
aniked [119]
For the answer to the question above,
<span>10x^2-36y^2=100
Then isolate x^2, first add 36y^2 to both sides: 10x^2 = 100 + 36y^2 divide both sides by 10:
x^2 = 10 + 3.6y^2 or
10 + 36/10 * y^2 = 10 + 18/5 * y^2
</span>
So the answer to this question is
<span><span>x2</span>=10 + (<span>18/5)</span><span>y2

I hope my answer helped you. Have a nice day!</span></span>

Please help<br><br> Write an inequality for the given graph
Oduvanchick [21]

Answer:

 y < 1/2x - 3

Step-by-step explanation:

You can write the inequality equation for the graph using the form y = mx + b. The inequality line has a y-intercept at (0,-3). This means b = -3. It also has a slope of 1/2 since the line moves up 1 and over 2 to the next point on the line.

This means the lines equation is y = 1/2x - 3. But since this is an inequality, you must use an inequality sign. Since the line is dashed it is not equal to. Your options are < and >.  Use the point (0,0) to test which sign is appropriate.

y < 1/2x - 3                      y > 1/2x - 3

0 < 1/2(0) - 3                   0 > 1/2(0) - 3

0 < -3                              0 > -3

The answer is y < 1/2x - 3 since (0,0) doesn't make it true and (0,0) is not shaded in the graph. This means it is not a solution.

Find all natural numbers n such that 1+3+5+7+...+(2n-1) sum is divisible by 4
Ierofanga [76]

n ∈ natural even numbers

Step-by-step explanation:

1 + 3 + 5 + 7 + … + (2n-1)

  • a = 1
  • b = 2
  • Uₙ = 2n - 1

sum of the first n terms :

Sₙ = n/2(a + Uₙ)

Sₙ = n/2(1 + 2n - 1)

Sₙ = n/2(2n)

Sₙ = n²

∴ so, the solution of n is all natural even numbers
