Tell whether the given value is a solution of the inequality.
x + 1 > 10; x = 9
Answer:
given x+1 > 10,
x > 10 - 1
x > 9
which means x MUST BE more than 9 , which also means 9 isnt included in the inequality therefore x = 9 is not a solution.

If f(x) is an exponential function where f(3) = 18 and f(7.5) = 60, then find the
value of f(12), to the nearest hundredth.
Given:
f(x) is an exponential function where f(3) = 18 and f(7.5) = 60.
To find:
The value of f(12), to the nearest hundredth.
Solution:
Let the exponential function be
[tex]f(x)=ab^x[/tex] ...(i)
It is given that [tex]f(3) = 18[/tex]. Substitute [tex]x=3[/tex] in (i).
[tex]f(3)=ab^3[/tex]
[tex]18=ab^3[/tex] ...(ii)
It is given that [tex]f(7.5) = 60[/tex]. Substitute [tex]x=7.5[/tex] in (i).
[tex]f(7.5)=ab^{7.5}[/tex]
[tex]60=ab^{7.5}[/tex] ...(iii)
Divide (iii) by (ii).
[tex]\dfrac{60}{18}=\dfrac{ab^{7.5}}{ab^3}[/tex]
[tex]\dfrac{10}{3}=b^{4.5}[/tex]
[tex]\left(\dfrac{10}{3}\right)^\frac{1}{4.5}=b[/tex]
[tex]b\approx 1.30676[/tex]
Putting [tex]b=1.30676[/tex] in (ii), we get
[tex]18=a(1.30676)^3[/tex]
[tex]\dfrac{18}{(1.30676)^3}=a[/tex]
[tex]a\approx 8.0665[/tex]
Putting [tex]a=8.0665[/tex] and [tex]b=1.30676[/tex] in (i), we get
[tex]f(x)=8.0665(1.30676)^x[/tex]
Putting x=12, we get
[tex]f(12)=8.0665(1.30676)^{12}[/tex]
[tex]f(12)=200.0024[/tex]
[tex]f(12)\approx 200.00[/tex]
Therefore, the value of f(12) is about 200.00.

Holly operates a fruit bouquet business. Function f represents the costs, in dollars, that Holly incurs when she creates x bouquets to sell. Function g represents the revenue, in dollars, Holly receives from selling x bouquets. Which combination of functions f and g represents the profits, in dollars, Holly earns when she creates and sells x bouquets? A. (f − g)(x) B. (fg)(x) C. (g − f)(x) D. (g + f)(x)
Answer:
C. (g − f)x
Step-by-step explanation: Subtract costs (f) from revenue (g) and multiply by bouquets made (x) to find profit.
Example would be if it costs $1 to make each bouquet and she charges $3 for each bouquet made. If she made 5 and sold them it would be...
(g-f)x
(3 - 1) 5 = profit
(2) 5 = $10 profit

"regrouping 1 tenth into 10 hundredths" is taking one of those green tenth sticks and dividing it into 10 hundredth squares. That means that you have 2 wholes, 2 tenths (remaining green sticks), and 10 hundredths (because the only hundredths you have are the ones you got from that tenth you regrouped).
After crossing them out, you have 2 wholes, 0 tenths (because you only had 2 before), and 4 hundredths (because you crossed out 6 of the 10, 10-6=4).

what is the circumference of a circle with a diameter of 40
The circumference of the circle with a diameter of 40 is approximately 125.6636 units.
To calculate the circumference of a circle, we can use the formula:
Circumference = π * Diameter
Given that the diameter of the circle is 40, we can substitute this value into the formula:
Circumference = π * 40
The value of π (pi) is approximately 3.14159, so we can further simplify the equation:
Circumference ≈ 3.14159 * 40
Calculating this expression gives us:
Circumference ≈ 125.6636
Therefore, the circumference of the circle with a diameter of 40 is approximately 125.6636 units. Note that the unit of measurement is not provided in the question, so the answer is given in generic units.

Tony love finding the area, such as pizza slices. His favorite pizza is a pepperoni with mushrooms that he can't stop talking about. The diameter is 18 inches and it is always cut into 6 slices of exactly the same size. In terms of pi, what is the surface area of one slice of the large pizza? (hint: think of the pizza as a sector you want to find the area of). Fill in your answers in the form of a fraction, aπb. You do not need to worry about pi as it is already built into the answer.
Answer:
[tex]\frac{27\pi }{2}[/tex] square inches.
Step-by-step explanation:
The pizza would have a circular shape so that dividing it into 6 slices implies that there are 6 sectors.
The central angle formed by each sliced pizza = [tex]\frac{360}{6}[/tex]
= [tex]60^{o}[/tex]
Given that the diameter = 18 inches, thus;
radius = [tex]\frac{18}{2}[/tex]
= 9.0 inches
Since the sliced pizza now has the shape of a sector, then;
the surface area of each large pizza = (θ/360)* [tex]\pi[/tex][tex]r^{2}[/tex]
= [tex]\frac{60}{360}[/tex]*[tex]\pi[/tex]*[tex](9)^{2}[/tex]
= [tex]\frac{1}{6}[/tex]*[tex]\pi[/tex]*81
= 13.5[tex]\pi[/tex] square inches
Surface area of each large pizza = [tex]\frac{27\pi }{2}[/tex] square inches
The surface are of one slice of the large pizza is [tex]\frac{27\pi }{2}[/tex] square inches.

Also, DC = 4 and BC = 2.
Find the length of the radius of circle A.
3
5
6
12.
Answer:
AB = 3
Step-by-step explanation:
AB = AD
AB² + 4² = (AB + 2)²
AB² + 16 = AB² + 4AB + 4
combine like terms:
4AB = 12
AB = 3
The length of the radius of the circle is 3 units.
The correct option is A.
What is Pythagoras' theorem?In a right-angled triangle, the square of the hypotenuse side is equal to the sum of the squares of the other two sides, according to Pythagoras's Theorem.
Given:
Circle A is shown in the given image.
And segment DC is tangent to circle A at D.
DC = 4 and BC = 2.
The radius of the circle = AB = AD.
So, by the Pythagoras' theorem,
(AB + 2)² = (AB)² + (CD)²
(AB + 2)² = (AB)² + 16
(AB)² + 4AB + 4 = (AB)² + 16
4AB = 12
AB = 12/4
AB = 3
Therefore, AB = 3 units.

Define prime numbers with example and way to find the prime numbers by sieve Eratosthenes?
Answer:
A prime number is a natural number greater than 1 that is not a product of two smaller natural numbers. A natural number greater than 1 that is not prime is called a composite number. For example, 5 is prime because the only ways of writing it as a product, 1 × 5 or 5 × 1, involve 5 itself.
In mathematics, the sieve of Eratosthenes is an ancient algorithm for finding all prime numbers up to any given limit. It does so by iteratively marking as composite the multiples of each prime, starting with the first prime number, 2

Describe how to determine if two lines are parallel, perpendicular or neither. Give an example of a parallel line, a perpendicular line and a line which is neither parallel nor perpendicular to y=2/5x+7.
Answer:
In order to determine if two lines are parallel, perpendicular, or neither, look at their slopes. If the lines have the same slope, they are parallel. If the slopes are opposite reciprocals, then they are perpendicular. If the slopes of the lines are not any of those, then they are neither.
Parallel line: [tex]y = \frac{2}{5} x[/tex]
Perpendicular line: [tex]y = -\frac{5}{2} x[/tex]
Neither: [tex]y = 3x[/tex]
Step-by-step explanation:
In order to determine if two lines are parallel, perpendicular, or neither, look at their slopes. If the slopes of the two lines are the same, then they are parallel. If the slopes of the two lines are opposite reciprocals, then they are perpendicular. If the slopes of the lines are not any of those, then they are neither.
The equation [tex]y = \frac{2}{5} x+7[/tex] is in slope-intercept form. The y is isolated and it's in [tex]y = mx + b[/tex] format. Whenever an equation is in slope-intercept form, the [tex]m[/tex], or the coefficient of the x-term, represents the slope. So, the slope of the given line is [tex]\frac{2}{5}[/tex]. Therefore, use the rules listed previously to find lines that are parallel and perpendicular.
Parallel lines have the same slope, so an example of a parallel line would be [tex]y = \frac{2}{5} x[/tex].
Lines that are perpendicular have slopes that are opposite reciprocals, so an example of a perpendicular line would be [tex]y = -\frac{5}{2} x[/tex].
Lines that are neither do not fall into either of those categories, so an example of a line that is neither would be [tex]y = 3x[/tex].
