The area of a parallelogram is 8x^2+2x-6 and it's height is 2x+2. What is the base of the parallelogram?​

Answers

Answer:

4x - 6

Step-by-step explanation:

Remember the formula for finding the area of a parallelogram;[tex](base)*(height)=(area)[/tex]

Manipulate the equation such that it is solved for the base;

[tex](base)=\frac{(area)}{(height)}[/tex]

So the equation that needs to be solved is;

[tex]\frac{(8x^{2} + 2x - 6 )}{(2x + 2)}[/tex]

Set up the division problem and solve;

              _____4x - 6___

[tex]2x + 2[/tex]     | [tex]8x^{2} + 2x - 6[/tex]

A new car is purchased for $17,000 and over time its value depreciates by one half every 3 years. What is the value of the car 19 years after it was purchased, to the nearest hundred dollars?

Answers

Answer:

The answer is "$238".

Step-by-step explanation:

Current worth[tex]= \$ 17,000[/tex]

depreciates by [tex]\frac{1}{2}[/tex] in 3 years.

time=  19 years

depreciates rate=?

Using formula:

[tex]\to \text{Worth= Current worth}(1- \frac{\text{depreciates rate}}{100})^{time}[/tex]

[tex]\to A_t=A_0(1-\frac{r}{100})^t[/tex]

calculates depreciate value in 3 year [tex]= \frac{1}{2} \times 17,000[/tex]

                                                              [tex]= 8,500[/tex]

so,

[tex]A_t=8,500\\\\A_0=17,000\\\\t=3\ years[/tex]

[tex]\to A_t=A_0(1-\frac{r}{100})^t\\\\\to 8,500= 17,000(1-\frac{r}{100})^3\\\\\to \frac{8,500}{17,000}= (1-\frac{r}{100})^3\\\\\to \frac{1}{2}= (1-\frac{r}{100})^3\\\\\to (\frac{1}{2})^{\frac{1}{3}}= (1-\frac{r}{100})\\\\\to 0.793700526 = (1-\frac{r}{100})\\\\\to \frac{r}{100} = (1-0.793700526)\\\\\to \frac{r}{100} = (1-0.8)\\\\\to r= 0.2 \times 100 \\\\\to r= 20 \%[/tex]

depreciates rate= 20%

[tex]\to \text{Worth= Current worth}(1- \frac{\text{depreciates rate}}{100})^{time}[/tex]

[tex]= \$ 17,000 (1- \frac{20}{100})^{19}\\\\= \$ 17,000 (1-0.2)^{19}\\\\= \$ 17,000 (0.8)^{19}\\\\= \$ 17,000 \times 0.014\\\\= \$ 238[/tex]

How many distinct permutations can be made from the letters of the word

“INDEPENDENCE”?


if anyone could answer, thank you (^-^)​

Answers

Answer:

360

Step-by-step explanation:

Word INDEPENDENCE has I−1, N−3, D−2, E−4, P−1, C−1

There are six different letters in INDEPENDENCE

Now according to the question, we need to form 4 different letter words, So the selection of 4 words out of 6 is  

[tex]^{6}C _{4}[/tex]

 and making its arrangements

So total number of ways is  

[tex]^{6}C _{4}[/tex] ×4!=360

The number of distinct permutations can be made from the letters of the word “INDEPENDENCE” is; 1663200

We are given the word INDEPENDENCE and it has;

I − oneN - threeD − twoE - fourP - oneC - one

Thus, we see that there are six different letters and 12 letters in total in INDEPENDENCE

Now from the question, the distinct permutations that can be formed is;

12!/(3! × 2! × 4!) = 1663200

We know that velocity is 85 feet/minute, and distance is velocity * time, so we can multiply 85 by time to see if it equals the output

(A) 1*85-85

(B) 0.85*85 = 72.75

Q4:     [tex]\frac{x(x+2)}{(x-4)^{2}(x+5) }[/tex]

Step-by-step explanation:

If there is a vertical asymptote at x=k, then the denominator must contain a term (x-k) or (x-k) raised to a positive integer power.

If there is an x intercept at k, then the numerator must contain a term (x-k) or (x-k) raised to a positive integer power.

If there is a horizontal asymptote of 0, then the highest power of x in the denominator must exceed the highest power of x in the numerator.

If thee is a horizontal asymptote of k, then the highest power of x in the numerator and denominator must be the same and the ratio of their coefficients (numerator to denominator) must be k.

Answer:

Step-by-step explanation:

Therefore school and friend's house is 15 miles away from each other.

What is distance?

The length of the line segment connecting two places is called the distance between them. The length of the line segment connecting the specified coordinates can be used to compute the distance between two points in coordinate geometry. Let's look at the formula for calculating the distance between two points in two and three dimensions.

How to  calculate?

If distance from my house to friend's house is x and from school to friend's house is y then  distance=[tex]\sqrt{x^{2} +y^{2} }[/tex]

As it form 90degree so we can apply this formula.( Or  can use trigonometric rule directly which is same.)

=[tex]\sqrt{9^{2}+12^{2}[/tex]

The answer is (2,6)
X:2
Y:6

Answer:

x = 2

y = 6

Step-by-step explanation:

We have a system of equations and are asked to solve for x and y.

y = -2x + 10

y = 3x

Since both equations start with y, we can subtitute.

3x = -2x + 10

Solve for x :

Add 2x to both sides :

5x = 10

Divide 5 from both sides :

x = 2

Now substitute x in the second equation because it's more easier :

y = 3(2)

A pair of numbers has an HCF (Highest Common Factor) of 7 , and an LCM (Lowest Common Multiple) of 42 . What is the pair of numbers

Answers

Answer:

14 and 21

Step-by-step explanation:

This is not an easy question, but luckily we can have an idea to solve this.

In this case, we need to apply the relation between HCF and LCM, which is the following:

HCM * LCM = Number 1 * Number 2

In other words, the multiplication of both factors is equal to the multiplication of the given numbers that we are looking for. Now, we do not know the numbers but we can have an idea of which numbers can be when we calculate the product of the factors:

HCM * LCM = 42 * 7 = 294

We know that the products should result 294, and if the HCM is 7, means that both numbers can be divided by 7 as the highest factor, so, let's write the multiple of 7:

Multiples of 7:

7, 14, 21, 28, 35, 42, 49, 56, 63, 70

With these we can have an idea, if 42 * 7 = 294, all we just need is to find others two numbers that the result gives 294:

14 * 7 = 98

14 * 21 = 294

14 and 21 could be the numbers, but let's confirm writting their multiples

HCM of 14: 1, 2, 7, 14

HCM of 21: 1, 3, 7, 21

LCM of 14: 14, 28, 42, 56, 70

LCM of 21: 21, 42, 63, 84

As you can see, The HCM and LCM of 14 and 21 are 7 and 42, therefore the pair of numbers are:

14 and 21
