Answer:

6.Step-by-step Difference Between Rhombus and Parallelogram. A parallelogram is a quadrilateral or four-sided figure in which the opposite sides are parallel. And because the opposite lines are parallel, hence the opposite angles are also equal. A rhombus, on the other hand, may be defined as an equilateral parallelogram ion.

7.A rectangle is a quadrilateral with all four angles right angles. It follows form this that the opposite sides are parallel and of the same length. A square is a quadrilateral with all four angles right angles and all four sides of the same length.

8.Trapezoids have only one pair of parallel sides; parallelograms have two pairs of parallel sides. A trapezoid can never be a parallelogram. The correct answer is that all trapezoids are quadrilaterals. ... Trapezoids are four-sided polygons, so they are all quadrilaterals.

Does anyone know the answer to this?

Answer:

(B) The exponents should be subtracted by the quotient rule of exponents

Step-by-step explanation:

Let's examine how this was solved.

$(\frac{4^2 4^3}{4^{-5}})^2$

He first rose everything in the parentheses to the second power, which is just multiplying all the exponents by 2. This is correct.

$\frac{4^4 4^6}{4^{-10}}$

He then combined the numerator exponents. Exponent rules say that $a^b \cdot a^c = a^b+c$ , so he should have ended up with $4^{10}$ , which he did. This is correct.

$\frac{4^{10}}{4^{-10}}$

Now, what he did in the final step is wrong. He added the exponents. However, exponent rules tell us that when we have $\frac{a^b}{a^c}$ , it equals $a^{b-c}$ .

$10 - (-10) = 10+10 = 20$

So the final answer should have been $4^{20}$

Hope this helped!

. Find the value of $1,300 invested at 4.2% interest compounded continuously for 5 years, 9 months. Round your final answer to t

BARSIC [14]

The formula we use for continuous compounding is $A=Pe ^{rt}$ where P is the initial amount invested, r is the rate as a decimal, and t is time in years. Our P = 1300, our r = .042, and our t = 5.75 (9 months is 3/4 of a year, and 3/4 in a decimal is .75). Putting all that into our formula we have $A=1300(2.718) ^{(.042)(5.75)}$ . We have to multiply those 2 powers together and then raise euler's number to it, then multiply by 1300. Doing all of that, we get the amount at the end to be $1,655.10

Answer:

336 version

Step-by-step explanation:

To determine the total possible number of combination we will use the product rule

Total numbers of exterior colour 7

Total number of interior colour 3

Total number of interior style 4

Total number of transmission option 2

Total number of engine option 2 therefore the total combination is

7*3 *4*2*2 = 336 possible combination
