What is the molar mass of ammonia gas nh3 round to four significant figures?.

Answer: a and c

Step-by-step explanation:

The 4 properties of multiplication are Associative Property, Commutative Property, Distributive Property, and Identity Property.

The properties of multiplication are particular rules that are used while multiplying numbers. These properties help simplify expressions easily and, hence, have a significant role in solving all kinds of mathematical expressions, whether algebraic expressions, fractions, or integers.

Associative Property: (P × Q) × R = P × (Q × R)

For example, (4 × 5) × 3 = 4 × (5 × 3) = 60.

Commutative Property: P × Q = Q × P

For example, 3 × 4 × 2 = 2 × 3 × 4 = 24.

Distributive Property: P(Q + R) = PQ + PR; P(Q - R) = PQ - PR

For example, 3(2 + 4) = (3 × 2) + (3 × 4) = 6 + 12 = 18.

Identity Property: P × 1 = P

For example, 4 × 1 = 4, or 1 × 27 = 27.

A right triangle's hypotenuse is its longest side, its "opposite" side is the one that faces a certain angle, and its "adjacent" side is the one that faces the angle in question.

A right triangle's hypotenuse is always the side that faces away from the right angle. It is the right triangle's longest side. The adjacent and opposing sides are the other two sides. These sides have labels that relate to angles. From a particular angle, the other side is across.

The non-hypotenuse side next to a specific angle is referred to as the neighboring side. Sine, cosine, and tangent are three trigonometric functions that are defined by the terms hypotenuse, opposite, and adjacent.

The balance in the account of Jayden after 5 years will be $3,886.27.

A loan or deposit's interest is computed using the starting principle and the interest payments from the ago decade as compound interest.

We know that the compound interest is given as

A = P(1 + r)ⁿ

Where A is the amount, P is the initial amount, r is the rate of interest, and n is the number of years.

Jayden invests $2,644.93 in a retirement account with an interest rate of 8% compounded annually. Then the amount after 5 years is calculated as,

A = $2,644.93 x (1 + 0.08)⁵

A = $2,644.93 x (1.08)⁵

The average temperature during the winter in the Arctic tundra i -34C which is also 93.2 degrees Fahrenheit

The difference between the freezing point of water and its boiling point at normal atmospheric pressure is divided into exactly 100 equal parts to determine the temperature in degrees Celsius (degrees). Water has a freezing point set at 0° and a boiling point set at 100°.

Therefore, a 100°C difference is precisely equivalent to a 180°F difference. As a result, each degree in Celsius is equivalent to 1.8 degrees Fahrenheit.

The 34 Celsius to Fahrenheit formula is a linear function:

[°F] = ([34] x 9 ⁄ 5) + 32.

Therefore, we get:

34 C to F = 93.2 °F

Natalie added three more games and two he formed a pattern of four. They realized they could add 3 matches to each round to get an extra '4'. From this, they concluded that, in general, 4 + 3 (n-1) double crochet stitches are required to create n 4 patterns. Here 4+ 3(n-1) is called an algebraic expression.

(gof)(x) is a function that takes the input x and returns 3 if x = 1, 2, or 4, and 4 if x = 3.

To find the composite function (gof)(x), we first apply the function g to the input x, then apply the function f to the result.

For example, if we want to find (gof)(2), we first find g(2) = 2, then find f(2) = 4, so (gof)(2) = f(g(2)) = f(2) = 4.

So to find (gof)(x) we have to substitute the value of x in function g, then the output of function g in function f.

For the given set of functions f and g, the composite function (gof)(x) is:

(gof)(1) = f(g(1)) = f(3) = 3

(gof)(2) = f(g(2)) = f(2) = 4

(gof)(3) = f(g(3)) = f(4) = 3

(gof)(4) = f(g(4)) = f(3) = 3

Step-by-step explanation:

Since we are given CDE ~ KLM, we know that C is similar to K, D is similar to L, and E is similar to M. The problem asks to find DE, so by comparison, it is known that DE is similar to LM.

From the two triangles, KM is similar to CE, and we can see that the ratio between the two is 8:15. We are given LM, which is 12, so we can find x using this equation to compare the smaller triangle to the bigger one:

KM/CE = LM/DE

Yes, the equation 9x^2 = 1 has zeroes at ±1/3. The solution is obtained by solving the algebraic equation.

What is algebraic equation?

The term "algebraic expression" refers to a mathematical expression that contains variables, constants, and algebraic operations (addition, subtraction, etc.). The expression must have an equals to sign in order to satisfy the algebraic equation.

We are given 9x^2 = 1

In order to find its roots, we need to find the value of x which are the zeroes for the equation.

So,

⇒9x^2 = 1

⇒x^2 = 1/9

⇒x = √1/9

⇒x = ±1/3

We are given 3x-1 = 0

So,

Every function has an inverse, but not every inverse will be a function.

A function takes a starting value, performs some operation on this value, and creates an output answer.

The inverse function takes the output answer, performs some operation on it, and arrives back at the original function's starting value.

An inverse relation is the set of ordered pairs obtained by interchanging the first and second elements of each pair in the original function.

A function is a one-to-one function if and only if each second element corresponds to one and only one first element.
