You should factorize so
P2 + 24p + 23
P2 + 23 p + p + 23
P(p + 23) + 1(p + 23)
(p + 23) and ( p + 1) are the factors

if f(x) = a^x. and f(4) = 256 find f(5). assume a>0
Answer:
[tex]f(5)=1024[/tex]
Step-by-step explanation:
We have the function:
[tex]f(x)=a^x[/tex]
Where a>0.
We know that f(4)=256. Therefore:
[tex]\displaystyle f(4)=a^4=256[/tex]
So:
[tex]a^4=256[/tex]
Find the value of a. Take the fourth root of both sides:
[tex]a=\sqrt[4]{256}=4[/tex]
Therefore, our function is:
[tex]f(x)=4^x[/tex]
Hence:
[tex]f(5)=4^5=1024[/tex]

A dishonest shopkeeper has two false balances. One balance weighs 10% more while
buying the goods and other weighs 10% less while selling the goods. Find his gain
percent just by weighing,
Answer:
Shopkeepers gain just by weighing is 22.22%
Step-by-step explanation:
Explanation:
Assume that the shopkeeper bought x units of goods i.e. actual weight of goods.
As the balance used to buy goods weighs 10% more, he actually bought x×110100=1.1x weight units i.e. although the shopkeeper paid for x units, he actually bought 1.1x units by weight.
Now he has 1.1x units of goods, but for selling he uses another balance, which actually measures 10% less i.e. 1−0.10=0.9 units for each unit weight of goods sold.
So while selling 1.1x becomes 1.1x0.90=1.2222... units.
Hence, shopkeepers gain just by weighing is 22.22%

Step-by-step explanation:

The value of sin(80) cos(20°) - cos(80°) sin(20°)= √3/2
What is Trigonometry?Trigonometry the area of mathematics that deals with particular angles' functions and how to use those functions in calculations. There are six common trigonometric functions for an angle. Sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant are their respective names and abbreviations.
Given:
sin(80) cos(20°) - cos(80°) sin(20°)
Using Trigonometric identity
sin ( A- B) = sin A cos B - cos A sin B
So, sin(80) cos(20°) - cos(80°) sin(20°)
= sin (80 - 20)
= sin 60
= √3/2
Hence, sin(80) cos(20°) - cos(80°) sin(20°)= √3/2

Calculate the simple interest on $600 left in account that pays 7% annual interest for 8 years.
Answer:
S = $336
Step-by-step explanation:
Given the following data;
Principal, P = $600
Rate, R = 7
Time, T = 8 years
To find the simple interest?
Mathematically, it is given by the formula;
Simple interest, S = (P*R*T)/100
Substituting into the equation, we have;
S = (600*7*8)/100
Simplifying the equation, we have;
S = 6*7*8
S = $336
Write an equation in point-slope form and slope-intercept form for
each line.
the line passes through (4, 7), slope = 2
Answer: y=2x-1
Step-by-step explanation:
Equation of a line that passes through (a,b) and have slope m is given by :-
[tex](y-b)=m(x-a)[/tex] [point slope form]
Given, Point = (4,7) , m= 2
Equation in point slope form : [tex](y-7)=2(x-4)[/tex]
To write in slope intercept form (y=mx+c) , we need to simplify it
[tex]y-7= 2x-8\\\\\Rightarrow\ y-2x=-8+7\\\\\Rightarrow\ y-2x=-1\\\\\Rightarrow\ y=2x-1[/tex]
Hence, y=2x-1

Find the domain of the relation {(0, 0), (1, 1), (2, 0)). Then determine whether
the relation is a function.
Answer:
Domain: 0,1,2
The relation is a Function.
Step-by-step explanation:
hope this helps
A relation may or may not be a function.
The domain of the relation is: [0,2]The relation is a functionThe relation is given as:
[tex]\mathbf{(x,y) = \{(0,0),(1,1),(2,0)\}}[/tex]
List out the x-values
[tex]\mathbf{x = \{0,1,2\}}[/tex]
The above set means that the x-values starts from 0 and ends at 2.
Hence, the domain is: [0,2]
For a relation to be a function, all y-values of the relation must point to different x-values.
So, we can say that, the given relation is a function, because all y-values have unique x values
