What is the domain of the function y =√x+6-7 ?
x>_-7
x>_-6
x>_6
x>_7

Answer:

x = 15.25

y = 71/6

Step-by-step explanation:

10x -9y = 46

-2x + 3y = 5

Time the second equation by 5

10x - 9y = 46

-10x + 15y = 25

6y = 71

y = 71/6

Now put 71/6 back in for y and solve for x

10x -9(71/6) = 46

10x -106.5 = 46

10x = 152.5

x = 15.25

Let's check

-2(15.25) +3(71/6) = 5

-30.5 + 35.5 = 5

5 = 5

So, x = 15.25 and y = 71/6 is the correct answer.

The equation of the ellipsoid is[tex]\frac{x^{2} }{a^{2} } + \frac{y^{2} }{b^{2} } +\frac{z^{2} }{c^{2} } =1[/tex]

The equation of an ellipsoid is represented as:

[tex]\frac{x^{2} }{a^{2} } +\frac{y^{2} }{b^{2} } +\frac{z^{2} }{c^{2} } =1[/tex]

Given that the ellipsoid passes through the points (±6,0,0),(0,±7,0) and (0,0,±5)

It means that:

(±a,0,0)  = (±6,0,0)

(0,±b,0) = (0,±7,0)

(0,0,±c) = (0,0,±5)

By comparison, we have:

±a=±5

±b=±6

±c=±7

So, the equation of the ellipsoid becomes:

[tex]\frac{x^{2} }{a^{2} } +\frac{y^{2} }{b^{2} } +\frac{z^{2} }{c^{2} } =1[/tex]

By substituting the values, the equation of the ellipsoid becomes is

[tex]\frac{x^{2} }{36}+\frac{y^{2} }{49} +\frac{z^{2} }{25} =1[/tex]

.An ellipse is the set of all points on a plane whose distance from two fixed points F and G add up to a constant. In an ellipse, there are two radius measures, one horizontally along the x-axis, the other vertically along the y-axis.For  a circle both these have the same value.

The total mass of the 135 boxes that the woman bought is 2358.7 kg

An equation is an expression that shows the relationship between numbers and variables using mathematical operators like addition, subtraction, multiplication and division. Equations can be linear, quadratic.

Each bottle of water has a mass of 728g. A box of mineral water contains 24 bottles from a given factory, hence:

Mass of each box = 24 bottles * 728 g per bottle = 17472 g

The woman bought 135 boxes, therefore:

Total mass of boxes =  135 boxes * 17472 g per box = 2358720 g

But 1 kg = 1000 g

2358720 g = 2358720 g * 1 kg per 1000 g = 2358.7 kg

Answer:

Step-by-step explanation:

this is so confusing

The moment of inertia (I) is a measure of an object's resistance to rotational motion around an axis. The moment of inertia of a cylinder can be calculated using the following formula:

I = (1/2) × m × r²

where:

I is the moment of inertia of the cylinder

m is the mass of the cylinder

r is the radius of the cylinder.

Here are the steps to calculate the moment of inertia for a cylinder:

Determine the mass of the cylinder. This can be done by weighing the cylinder on a scale or by using its density and volume. The formula for the mass of a cylinder is:

m = density × volume

Measure the radius of the cylinder. This is the distance from the center of the cylinder to its outer edge.

Substitute the values of m and r into the moment of inertia formula:

I = (1/2) × m × r²

Calculate the moment of inertia using a calculator.

Note that the moment of inertia of a hollow cylinder is different from that of a solid cylinder. To calculate the moment of inertia of a hollow cylinder, you need to subtract the moment of inertia of the hollow space from the moment of inertia of the solid cylinder using the parallel axis theorem.

The weight gained by the spot dog during his time is 57/2 ounces.

An operation is a function in mathematics that converts zero or more input values, also known as "operands" or "arguments," into a clearly defined output value. The operation's complexity is determined by its operand count.

The most frequently studied operations are unary operations (i.e., operations of arity 1), which include additive inverse and multiplicative inverse, as well as binary operations (i.e., operations of arity 2), which include addition and multiplication. The nullary operation, also known as an operation of arity zero, is a constant. A ternary operation, also known as an operation of arity 3, is an example of the mixed product.

Given that, spot the Dog gained 4 3/4 ounces each week for the first 6 weeks of his life.

Convert the mixed fraction into improper fraction:

Answer:

The exponential growth function for the population can be written as:

P(t) = P0 * e^(rt)

Where:

P0 = initial population = 8,000

r = annual growth rate = 4.3% = 0.043

To find the monthly rate, we need to divide the annual rate by 12 (since there are 12 months in a year):

r_monthly = r/12 = 0.043/12 = 0.00358

So the exponential growth function with monthly growth rate becomes:

P(t) = 8000 * e^(0.00358t)

To find the quarterly rate, we need to divide the annual rate by 4 (since there are 4 quarters in a year):

r_quarterly = r/4 = 0.043/4 = 0.01075

So the exponential growth function with quarterly growth rate becomes:

P(t) = 8000 * e^(0.01075t)

What is DNA?

DNA (Deoxyribonucleic acid) is a patch that contains the inheritable instructions used in the development and functioning of all living organisms. It's a long, double-stranded, spiral structure made up of four different structure blocks called nucleotides, which are represented by the letters A, T, C, and G. The specific sequence of these nucleotides along the length of the DNA patch determines the inheritable law of an individual organism and is responsible for its unique characteristics and traits. DNA is located in the nexus of cells and is organized into structures called chromosomes. It's essential for the replication of cells and the transmission of inheritable information from one generation to the coming.

The metric system is an internationally recognized system of measurement that is used in many countries around the world. It is also known as the International System of Units (SI), and it is based on a decimal system, meaning that units are related to each other by powers of 10.

The metric system has a set of base units that are used to measure different types of quantities. The base units are:

Meter (m): used to measure length or distance

Kilogram (kg): used to measure mass or weight

Second (s): used to measure time

Each base unit has a set of prefixes that can be used to create larger or smaller units. These prefixes are based on powers of 10, and they are added to the base unit to indicate the size of the unit. Here are the most common prefixes and their meanings:

Kilo- (k): 1000 times the base unit (e.g., 1 kilogram = 1000 grams)

Hecto- (h): 100 times the base unit (e.g., 1 hectometer = 100 meters)

Use the circle area formula to determine r.

r = sqrt(36)

r = 6

The circle has radius 6 units.

Answer:

[tex]\dfrac{9}{12} - \dfrac{11}{18} = \dfrac{5}{36}[/tex]

Step-by-step explanation:

We can solve this subtraction of fractions by converting both fractions to forms where they have a common denominator.

To do this, we first have to find the least common multiple (LCM) of their denominators.

    1. Write out the denominators' prime factorizations.

    12           18

    2, 2, 3     2, 3, 3

    2. Multiply the greatest multiple of each prime number.

    2² × 3² = 4 × 9 = 36

So, the LCM of the denominators is 36.

Next, we need to get both fractions' denominators to 36 by multiplying each one by {36 divided by them} over {36 divided by them}.

Remember, this is just multiplying by 1.

[tex]\left(\dfrac{9}{12} \times \dfrac{36/12}{36/12}\right) - \left(\dfrac{11}{18} \times \dfrac{36/18}{36/18}\right)[/tex]

↓ simplifying the fractions being multiplied

[tex]\left(\dfrac{9}{12} \times \dfrac{3}{3}\right) - \left(\dfrac{11}{18} \times \dfrac{2}{2}\right)[/tex]

↓ executing the multiplication

[tex]\dfrac{27}{36} - \dfrac{22}{36}[/tex]

Finally, we can subtract the fractions' numerators.

[tex]\dfrac{27}{36} - \dfrac{22}{36} = \boxed{\dfrac{5}{36}}[/tex]
