5.6e12 is another way of writing scientific notation.  This is the same as

5.6 x 10^12

The power of 10 tells us how many places to move the decimal.  This means we move it 12 places.  Since the exponent is positive, we are going to make the number larger; this means we move the decimal to the right.  Moving it 12 places gives us

5,600,000,000,000

The multiplication or product of the two numbers 4√2 and 2√6 is 16√3 option (1) is correct.

It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.

We have two numbers:

4√2 and 2√6

From the arithmetic operation we can multiply two numbers:

= 4√2x2√6

Here sign x represents the multiplication.

As we know, the number expression can be defined as the combination of constants and variables with mathematical operators.

√2x√6 = √(2x6) = √12

√12 = √(2x2x3)

√12 = 2√3

= 4√2x2√6

= 4x2√(2x6)

= 8√12

= 8(2√3)

= 16√3

Thus, the multiplication or product of the two numbers 4√2 and 2√6 is 16√3 option (1) is correct.

The equations that represent the relationship between the measure of the angles in the figure are:

D. a+b=180

E. 180-a=b

The measure of the angle of a straight line is 180 degrees.

In the given figure, KL is a straight line segment.

This means that the measurement of the angles of KL is 180 degrees.

This implies that,

Answer: decrease

Step-by-step explanation:Accounts payable are what the business owes. By paying off accounts payable, the liabilities are decreasing and the assets are also decreasing (because they use assets/cash to pay off the liabilities, so they have less now).

Answer:

The payment of accounts payable would decrease both assets and liabilities.

Accounts payable (AP) refers to a record inside the overall record that addresses an organization's commitment to take care of a momentary obligation to its leasers or providers. One more typical use of it alludes to the business office or division that is answerable for making installments owed by the organization to providers and different leasers.

In the event that AP increases over an earlier period, that implies the organization is purchasing more services and products on credit, instead of paying cash. In case an organization's AP decreases, it implies the organization is paying on its earlier period obligations at a quicker rate than it is buying new things using credit. And, the thing people or business uses to pay accounts payable in cash, which is an asset. So, basically, when you pay accounts payable, both your assets and liabilities will decrease.

Answer:

Correct option: fourth one -> y = 6(1/3)^x

Step-by-step explanation:

A decay curve is produced by an exponencial function with a rate lesser than 1 and greater than 0. This way, we have an exponencial function where the values of y decrease when the values of x increase.

The first equation is a linear equation.

The second and third equations are exponencial equations, but with a rate bigger than 1

The fourth equation is an exponencial equation with a rate lesser than 1 and greater than 0, so this equation will produce a decay curve.

Answer:

You can use the Law of Sines for this problem, but what makes it tough at first glance is that they put a step in before you can use it directly. That first step is to get m∠C. When solving a triangle, always get the third angle if you know the other two so that you can use the Law of Sines (or Law of Cosines) more directly.

The sum of the angles of any triangles is 180°. We know the measures of the two other angles. So we subtract them from 180° to find that third angle.

180° - 76° - 66° = 38°

Now we can use the proportion from the picture. Angle B measures 76°, side b is our unknown, Angle C measures 38°, and side c measures 3 units.

sin 76° sin 38°

----------- = -----------

b 3

Cross multiply to find b (the side). We carry out five places in these calculations to get more accuracy.

3 * sin 76° = b * sin 38°

b = 3 * sin 76° 3 * 0.56611 1.69832

--------------- = --------------- = ---------------- = 5.73044

sin 38° 0.29636 0.29636

To the nearest tenth, b - 5.7 units.

Step-by-step explanation:

Just solve for q. Because that's the output. h(r) = q

Answer: 6r+16

Step-by-step explanation: All you need to do is to simplify the equation q-10=6(r+1) It becomes q-10=6r+6. You then add 10 on both sides, resulting q=6r+16.

Step-by-step explanation:

Height² = 64

Height = 8

Volume = ⅓pi × r² × h

= ⅓ × 3.14 × 6² × 8

= 301.44 ft³

Answer:

V = 301 ft^3

Step-by-step explanation:

The volume of a cone is given by

V =1/3 pi r^2 h

We know pi = 3.14 r =6 and

We need to determine h

We can find h from the Pythagorean theorem where 6 is a leg and 10 is the hypotenuse

h^2 +6^2 = 10^2

h^2 +36 = 100

h^2 = 64

Taking the square root of each side

h = 8

V =1/3 pi r^2 h

V = 1/3 (3.14) (6)^2 * 8

V = 301.44 ft^3

Rounding to the nearest cubic foot

f(x) has 3 real roots

Step-by-step explanation:

According to the Fundamental theorem of Algebra.

A polynomial of degree n has n roots, which can be real or complex or both.

Thus a polynomial of degree 3 has 3 roots.

Two real roots are given

Complex roots occur in conjugate pairs, thus there cannot be an odd number of complex roots.

Thus f(x) has three real roots.
