Answer:

1730 inches cubed

Step-by-step explanation:

We can add in the missing piece of the shape, then subtract it later. The aquariam is 18 by 10 at the base and has a height of 11 (5+6).

18•10•11=1980

Now we need to figure the volume of the empty space. The empty space has dimensions of 5, 10, and 5.

5•5•10=250

1980-250=1730

Answer:

In my opinion both of the lines are tangent.

Step-by-step explanation:

Because a tangent to a circle is a straight line which touches the circle at only one point. This point is called the point of tangency. The tangent to a circle is perpendicular to the radius at the point of tangency.

Answer:

If the signs of rational numbers are same, then the answer is positive.

If the signs of rational numbers are different, then the answer is negative.

Step-by-step explanation:

Consider the provided information.

A: When multiplying or dividing rational numbers, when will the answer be positive?

If we are multiplying or dividing rational numbers the answer will be positive if and only if both the rational numbers have same sign.

For example: Multiply 2 and 4.

2×4=8 (same sign)

Multiply -2 and -4.

-2×-4=8 (same sign)

8 is a positive rational number.

Now divided 2 and 4.

$\frac{2}{4} =\frac{1}{2}$

Divided -2 and -4.

$\frac{-2}{-4} =\frac{1}{2}$

1/2 is a positive rational number.

Hence, If the signs of rational numbers are same, then the answer is positive.

B: When multiplying or dividing rational numbers, when will the answer be negative?

If we are multiplying or dividing rational numbers the answer will be negative if and only if both the rational numbers have different sign.

For example: Multiply 2 and -4.

2×-4=-8 (different sign)

Multiply -2 and 4.

-2×4=-8 (different sign)

-8 is a negative rational number.

Now divided 2 and -4.

$\frac{2}{-4} =-\frac{1}{2}$

Divided -2 and 4.

$\frac{-2}{4} =-\frac{1}{2}$

-1/2 is a negative rational number

Hence, If the signs of rational numbers are different, then the answer is negative.

$4x^2-9$

Here I have included 3 methods: Differentiating, Integrating and factorize

Differentiating:

$4x^2-9$

$2*4x^2^-^1$

$8x^2^-^1$

$= 8x$

Integrating:

$\int\limits 4x^2-9dx$

$\frac{4x^3}{3}-9x+C$

Factorise:

$(2x-3)(2x+3)$
