Answer:

-1

Step-by-step explanation:

So to solve this, it tells you that (3, -2) is a solution so you can substitute x = 3 and y = -2 into the equation which would look like this:

[tex]3*3-p*-2-7 = 0[/tex]

Then, you solve the equation for p:

first, simplify the left side

[tex]9 +2p-7=0\\2+2p=0[/tex]

subtract 2 from both sides

[tex]2p=-2[/tex]

divide both sides by 2

[tex]p=-1[/tex]

Now, you have p = -1!

hope that makes sense :D

Answer:

We conclude that a diagonal of a quadrilateral is a line segment that joins two opposite vertices of the quadrilateral.

Step-by-step explanation:

From the attached diagram, it is clear that the line segment AC of the parallelogram quadrilateral joins two opposite vertices A and C.

It is also clear that the other line segment BD of the parallelogram quadrilateral joins two opposite vertices B and D.

Therefore, we conclude that a diagonal of a quadrilateral is a line segment that joins two opposite vertices of the quadrilateral.

Answer:

  £66

Step-by-step explanation:

I like to work problems involving ratios by considering the value of each "ratio unit." Before we get that far, we need to finish the division ratios.

  Dan : Eva = 3 : 4

There are two remaining divisions, each getting half Eva's amount. That is, each of those gets 4/2 = 2 "ratio units." Then the full division ratios are ...

  Dan : Eva : Freddie : Gok = 3 : 4 : 2 : 2

for a total of 11 ratio units. Those 11 units represent £242, so each one represents £242/11 = £22. That makes Dan's 3 units worth ...

  3×£22 = £66 . . . the amount Dan gets

d. A matched-pairs t-interval for a mean difference.

Step-by-step explanation:

d. A matched-pairs t-interval for a mean difference.

There are many situations in which two samples are not independent. This happens when the observations are found as pairs and the observations are related in pairs.

When the observations from two samples are paired either naturally or by design , the difference between two observation of each pair is treated as normal population  with mean ud= u1=u2  and unknown standard deviation, one sample t- test can be performed on them.

This is called matched pairs t- interval for a mean difference.

In this experiment the basketball coach is investigating whether the number of shots taken can be used to predict the mean number of points scored.

We want to estimate the mean change in the number of points scored for each increase of 1 shot taken.

The two samples are not independent.

Step-by-step explanation:

The number of the tickets sold by john is 150.

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that John sold 750 tickets to a concert for $6,300. If the price of a student ticket was $8 and the price of an adult ticket was $10. The number of the tickets will be calculated as below:-

s and a are the numbers of student and adult tickets, respectively.

s+a = 750

s = 750-a

8s + 10a = 6300

8(750-a) + 10a = 6300

6000-8a + 10a = 6300

2a = 300

a = 150

Therefore, the number of tickets sold by john is 150.

56p

Step-by-step explanation:

dude it's mad easy just add it regularly then just add the p or other variable

Answer:

21+35p= 56p

Step-by-step explanation:

First, you take the numbers 21 and 35 and then add them.

Second, you take the variable (p) that you removed from 35 and add it to the end of 56.

This is to be done because you may separate the variable in order to find the solution but once done you must add the variable back in its place or else you will get the wrong solution.

If I calculated correctly, the tangent line is horizontal where x ≈ -5.3 + 9.3i, and -5.3 - 9.3i

I'm somewhat concerned at having gotten complex numbers, and strongly recommend going through the steps to see if I missed anything.  I checked it myself and don't see any errors.

Step-by-step explanation:

You can do this by taking the derivative of the function and solving for zero:

f(x) = 2x³ + 32x² + 220x + 11

f'(x) = 6x² + 64x + 220

f'(x) = 2(3x² + 32x + 110)

We can't factor that further, so let's do it the long way, starting by letting f'(x) equal zero:

0 = 2(3x² + 32x + 110)

0 = 3x² + 32x + 110

0 = 9x² + 96x + 990

0 = 9x² + 96x + 256 + 734

0 = (3x + 16)² + 734

(3x + 16)² = -734

3x + 16 = ± i√734

3x = -16 ± i√734

x = (-16 ± i√734) / 3

x ≈ (-16 + 27.9i) / 3, and  (16 - 27.9i) / 3

x ≈ -5.3 + 9.3i, and -5.3 - 9.3i

I'm always wary when I end up with complex numbers.  I'd suggest double checking everything here, but I'm fairly certain I did everything correctly.

The general form of exponential functions is [tex]a[/tex] · [tex]b^x^-^h +k[/tex]. If [tex]b[/tex], or the base with the exponent, is bigger than 1, than the graph increases, experiencing growth. If the base is somewhere between 0 and 1, then the graph decreases, experiencing decay.
