Answer:
b(x) = -2x² + 7x + 114
Step-by-step explanation:
Step-by-step explanation:
First we convert 50 cent into dollar,
1 cent = dollar
1 cent = 0.01 dollar
50 cent = 0.5 dollar
According to question,
x is the number of 50¢=$0.5 price increases.
b(x) is the revenue generated
He currently charges $3 per book.
i.e. price of book = 3+0.5x
Quantity or average = 38 per day
According to a study, for every 50¢ increase in rental price, the average business can expect to lose 4 rentals a day.
i.e. quantity became 38-4x
Revenue = Price × Quantity

Jack paid $21,000 for his new car. This was 7/8 the suggested selling price of the car. What was the suggested selling price of the car?
Answer:
$24000
Step-by-step explanation:
so we can make an algebraic equation with these values
21000=7/8x
divide both sides by 7
3000=1/8x
multiply both sides by 8
x=24000
Which of the following geometric series converges?
The geometric series that converges is II. 0.3 + 0.12 + 0.048 + 0.0192 ( Option A).
To determine whether a geometric series converges, we need to check if the common ratio (r) of the series lies between -1 and 1 (inclusive). If the absolute value of r is less than 1, the series converges; otherwise, it diverges.
Let's check each series:
I. 2.9 - 3.19 + 3.509 - 3.8599
To find the common ratio, we divide each term by the previous term:
r = (-3.19) / 2.9 ≈ -1.1 (diverges)
II. 0.3 + 0.12 + 0.048 + 0.0192
To find the common ratio, we divide each term by the previous term:
r = 0.12 / 0.3 = 0.4 (converges)
III. 4 - 16 + 64 - 256
To find the common ratio, we divide each term by the previous term:
r = -16 / 4 = -4 (diverges)
So, the convergent geometric series is II. 0.3 + 0.12 + 0.048 + 0.0192.

x^2 + 9x + 14 I need help !
Answer:
x² + 9x + 14 can be factored as (x+2)(x+7)
Step-by-step explanation:
The general form is ax² + bx + c. If a=1, then you can start looking for two numbers that multiplied give c and added give b.
14 = 2*7
and
9 = 2+7
hence the easy factorization
(x+2)(x+7)
Keep in mind that it only works if a=1.
Answer:
( + 2 ) (x+7 )
Step-by-step explanation:
Use the sum-product pattern 2 + 9 + 1 4 2 + 7 + 2 + 1 4 2
Common factor from the two pairs 2 + 7 + 2 + 1 4 ( + 7 ) + 2 ( + 7 ) 3
Rewrite in factored form ( + 7 ) + 2 ( + 7 ) ( + 2 ) ( + 7 )

Answer:
The value of y is 110 degrees
Step-by-step explanation:
-we know that the Angle sum property of a quadrilateral is 360 degrees.
- so we can find the 4th angle
- and find y through the linear pair method.
The fourth angle=70 degrees
And y=180-70=110(Linear pair)
Does anyone know the written equation to this please?
9514 1404 393
Answer:
y = -3/2x +4
Step-by-step explanation:
The line crosses the y-axis at y = 4. The coordinates of that point are (0, 4). This is the "start."
The line crosses a grid intersection again 2 units to the right and 3 units down at the point (2, 1).
The slope is the ratio of the vertical change to the horizontal change:
m = -3/2
Now, you have the information required to fill in the equation:
y = -3/2x +4
If there are 1.15 land miles in a nautical mile, how
many land miles are there in 10 nautical miles?
Answer:
11.5
Step-by-step explanation: Since there is 1.15 land miles in one nautical mile you multiply 1.15 by 10 to find how many land miles are in 10 nautical miles.
The number of land miles there in 10 nautical miles will be 11.5.
What is multiplication?Multiplication is the general procedure in mathematics in which we multiply two or more numbers by each other to find a new multiplied number.
If and only if the number being multiplied is more than one, multiplication produces a resultant number that is significantly larger than the original number.
As per the given,
One nautical mile = 1.15 land miles
In 10 nautical miles = 1.15 x 10 = 11.5 land miles
Hence "The number of land miles there in 10 nautical miles will be 11.5".

How do you write the algebraic expression 6 less than the quotient of 32 and a number y
Answer:
( 32/y ) - 6
Step-by-step explanation:
okay so quotient means the result obtained by dividing one quantity by another and the problem that follows that is 32 and a number, y
this is meaning that 32 and y and going to be dividing (32/y)
less than means subtraction and the number that's surrounding that is 6.
this means that 6 is going to be subtracted from (32/y)
hopefully this helped! good luck bud <3
I need help please answer these two questions for me! Will give points.
Answer:
7.) 7
10.) 0
Step-by-step explanation:
When it means "evaluate the function", it's in essence asking us to see what the function spits out when we feed it a certain input. Our inputs are our x values, which spit out a y value.
Evaluating the function when x = 1:
Let's look at where the function has an x value of 1. We see it near the bottom of the table and see the y value associated with the input is 7. So when the function is fed 1 as an input, it spits out 7.
Evaluating the function when f(x) = - 2:
This one is a weird because of the new notation. Just think of it as some value of f, which we don't know (so we represent it as an x-variable) must equal -2. So let's look at our table to find out where our output is -2. We find that when f(x) = -2 the input is 0. So the input which gives -2 is 0.

Answer:
the answer is 42.
Step-by-step explanation:
(8)(5)−8+(2)(5)
=42
Answer:
1: 42
2: 107.6 °F
Step-by-step explanation:
For question 1 you insert the x and y values into the expression:
8 × 5 = 40 (xy = 40)
40 - 8 = 32 (xy - x = 32)
2 × 5 = 10 (2y = 10)
32 + 10 = 42 (xy - x + 2y = 42)
For question two you insert the celsius value into the expression:
9/5 × 42 = 75.6 (9/5C = 75.6)
75.6 + 32 = 107.6 (9/5C + 32 = 107.6)

One little cat can eat a bag of treats in 15 minutes while another cat can eat the same bag of treats in 10 minutes. What part of the bag can they eat together in the given time? 1 minute.
Answer:
Step-by-step explanation:
The first cat eats 1/15 of a bag per minute.
The second cat eats 1/10 of a bag per minute.
Together, they eat 1/15 + 1/10 = 1/6 of a bag in one minute.
Hence both can eat [tex]\frac{2x+3y}{30}[/tex]
What is word problem?when we form equations out of given statements and then solve them to obtain answer are said word problems.
How to solve?Given cat x can eat treat = 15 mints
cat x in 1 mint= x/15
given cat y can eat treat = 10 mints
cat y in 1 mint= y/10
hence both cats if eat together =[tex]\frac{x}{15} +\frac{y}{10}[/tex]
=[tex]\frac{2x+3y}{30}[/tex]
hence both can eat [tex]\frac{2x+3y}{30}[/tex].

Given:
The figure of a right angle triangle.
To find:
The value of y.
Solution:
If a right angle triangle,
[tex]\cos \theta=\dfrac{Adjacent}{Hypotenuse}[/tex]
In the given right triangle,
[tex]\cos (30^\circ)=\dfrac{4\sqrt{3}}{y}[/tex]
[tex]\dfrac{\sqrt{3}}{2}=\dfrac{4\sqrt{3}}{y}[/tex]
[tex]\sqrt{3}\times y=2\times 4\sqrt{3}[/tex]
[tex]\sqrt{3}\times y=8\sqrt{3}[/tex]
Isolate the y variable.
[tex]y=\dfrac{8\sqrt{3}}{\sqrt{3}}[/tex]

If 0 is an angle in standard position and its terminal side passes through the point
(-7,24), find the exact value of sec 0 in simplest radical form.
Answer:
[tex] \frac { 5\sqrt{21} }{ - 7} [/tex]
Step-by-step explanation:
Firstly, let find some some other trig functions. We need to know all sides to know other trig functions. We know the horizontal side is -7 because it x-axis is at -7, it y-axis is at 24. so it vertical side is 24. Then we use the pythagorean theorem to find r
[tex] {7}^{2} + {24}^{2} = {r}^{2} [/tex]
49+576=
[tex] {c}^{2} [/tex]
525=c^2
[tex] \sqrt{525} = 5 \sqrt{21} [/tex]
So since we know that x= -7, y=24, r= 5 times sqr root of 21. We can find some trig functions. We can use function cosine here. Cosine equals
[tex] \frac{x}{r} [/tex]
cos=
[tex] \frac{ - 7}{5 \sqrt{21} } [/tex]
then we find secant which is the reciprocal of cos so we flip the numbers and that equals
[tex] \frac{5 \sqrt{21} }{ - 7} [/tex]
