simplify the expression 5x^(2n-1)+(2x^(3n+1))^2

Answer:

1.21

Step-by-step explanation:

5.26 - 3.64 = 1.62

1.62 ÷ 2 because the difference between 3 and 5 is two, the mass of one apple is 0.81 because 1.62 ÷ 2 = 0.81

so now we know one apple weights 0.81

if we multiply that 0.81 x 3 it will equal 2.43, so now the three apples alone wiegh 2.43...so now we look at the total weight of the whole basket with three apples, which is 3.64,

3.64 - the weigth of the apples (2.43)

3.64 - 2.43 = 1.21

the basket alone wieghts 1.21

Answer:

170 students were attending

Step-by-step explanation:

use a system of equations:

[tex]\left \{ {{x+y=300} \atop {9x+6y=2190}} \right.[/tex]  

let x be the adults and y be the students

[tex]\left \{ {{-9(x+y=300)} \atop {9x+6y=2190}} \right.[/tex]    multiply the top equation by -9 and add the two systems together to cancel out x. you are then left with:

[tex]-3y=-510[/tex]

divide both sides by -3 to leave y alone:

[tex]\frac{-3y}{-3}=\frac{-510}{-3}[/tex]

that would leave you with:

y=170

Answer:

Step-by-step explanation:

Just figured what numbers fit..

Do it in my head

The highest number is 10.

Let the numbers be a, a+1, a+2, a+3, a+4 and a+5.

Then, we will add all the numbers and equate them to 45. This will be:

a + (a + 1) + (a + 2) + (a + 3) + (a + 4) + (a + 5) = 45

6a + 15 = 45

Collect like terms

6a = 45 - 15

6a = 30

a = 30/6

a = 5

Smallest number = 5

Then, the largest number will be:

a + 5

Since a = 5

a + 5 = 5 + 5 = 10

In conclusion, the highest number is 10.

Answer:

$33.23

Step-by-step explanation:

If 18 apples cost $13, this means that each apple costs 1.38461538. To find the cost of 24 apples, multiply that decimal number by 24. You will get 33.2307692308. You can round this to 33.23.

Answer:

62%

Step-by-step explanation:

I took a fraction and made a decimal which was made into a percentage.

186 ÷ 300 = .62

Check: 62% • 300 = 186

The survey Anna conducted has 62% of students whose favorite color is red.

The percentage is the value per hundredth. Percentages can be converted into decimal form by dividing them by hundred, Percentage can also be represented as a fraction.

Given that 186 out of 300 students Anna surveyed chooses red as their favorite color.

The percentage of students whose favorite color is red is no. of students whose favorite color is red divided by the total no. of students multiplied by hundred which is,

= (186/300)×100.

= 186/3.

= 62%.

Answer:

No they are not parallel.  

Step-by-step explanation:

You have to figure out the slopes of each set of points. For  (-5,3) and (-6,-1) the slope is 4 and for  (3,-2) and (2,-7) the slope is 5. You can only have parallel lines if the slope is same and the y- ints are different. Here the slopes aren't same.

Sorry If im wrong. Hope this helps!

The two given lines are not parallel.

The slope is the ratio of the vertical changes to the horizontal changes between two points of the line.

Its slope would be:

[tex]m = \dfrac{y-q}{x-p}[/tex]

Slope of parallel lines are same. Slopes of perpendicular lines are negative reciprocal of each other.

We are given that;

The points= (-5,3) and (-6,-1),  (3,-2) and (2,-7)

Now,

For line A, let’s use (-5, 3) and (-6, -1) as the two points. Plugging these values into the formula, we get:

m = (-1 - 3) / (-6 - (-5)) = -4 / -1 = 4

So, the slope of line A is 4.

For line B, let’s use (3, -2) and (2, -7) as the two points. Plugging these values into the formula, we get:

m = (-7 - (-2)) / (2 - 3) = -5 / -1 = 5

Hence, the slope of line B is 5.

Since the slopes of line A and line B are not equal (4 ≠ 5),

Therefore, by the slope the answer will be they are not parallel.

Answer: Choice A.   f(x) = sqrt(x-1)

===========================================

Explanation:

The parent function is y = sqrt(x) and the left-most edge of this curve is at (0,0).

The graph shows the left-most point at (1,0) instead.

This means we've shifted everything 1 unit to the right, or you can think of the xy axis being shifted 1 unit to the left while the square root curve stays still (giving the illusion the curve moves).

If we shifted the xy axis 1 unit to the left, then each input x becomes one smaller, so each input is now x-1

That's why we go from y = sqrt(x) to y = sqrt(x-1)  

You can use a graphing calculator to confirm this, or you can create a table of values to generate the points on this new blue curve.

Answer:

its $63.96

Step-by-step explanation:

Using the formula (b) and replacing the given values:

Sale Price = Original Price - Amount Saved. So,

Sale Price = 79.95 - 15.99

Sale Price = $63.96 (answer).

This means the cost of the item to you is $63.96.

You will pay $63.96 for a item with original price of $79.95 when discounted 20%.

In this example, if you buy an item at $79.95 with 20% discount, you will pay 79.95 - 15.99 = 63.96 dollars.

Answer:

$63.96

Step-by-step explanation:

$79.95 = 100%

The jacket is on sale for 20% off, therefore it is 100% - 20% = 80% or 0.8

0.8 x $79.95 = $63.96
