Answer: Last option.
Step-by-step explanation:
To find the inverse of the function f(x), you must follow the proccedure shown below:
- Rewrite the function,as following:
[tex]y=4x+12[/tex]
- Solve for x. Then:
[tex]y-12=4x\\x=\frac{1}{4}y-\frac{12}{4}\\\\x=\frac{1}{4}y-3[/tex]
- Now, substitute y with x.
Therefore, you obtain that the inverse function g(x) is the following:
[tex]g(x)=\frac{1}{4}x-3[/tex]
Then, the answer is the last option.
Answer:
Last choice is the answer.
Step-by-step explanation:
We have given a function.
f(x) = 4x+12
We have to find the inverse of given function.
Let y = f(x)
y = 4x+12
Solving for x, we have
x = 1/4y-3
Since, x = f⁻¹(y)
f⁻¹(y) = 1/4y-3
Replacing y with x , we have
f⁻¹(x) = 1/4x-3
Given that g(x) = f⁻¹(x)
g(x) = 1/4x-3 which is the answer.
The equation for a parabola with directrix y = –p and focus (0, p) is:
Answer:
[tex]y=\frac{1}{4p}x^{2}[/tex]
Step-by-step explanation:
∵ The directrix is y = -p
∵ The focus is (0 , p)
∵ (x , y) is a general point on the parabola
∵ The distance between (x , y) and the directrix = the distance
between (x , y) and the focus
By using the rule of distance:
∵ (y - -p)² = (x - 0)² + (y - p)²
∴ (y + p)² = x² + (y - p)²
∴ y² + 2py + p² = x² + y² - 2py + p²
∴ 2py + 2py = x²
∴ 4py = x² ⇒ ÷ 4p in both sides
∴ [tex]y=\frac{1}{4p}x^{2}[/tex]
Your dog eats 7/8 lb of food in 4 meals , how many meals will it take your dog to eat 1 lb of food
Answer:
x = 32/7, or 4 4/7 meals
Step-by-step explanation:
Write and solve an equation of ratios, as follows:
7/8 lb 4 meals
------------ -------------
1 lb x
x will be the number of meals necessary for the dog to eat 1 lb of food.
Cross-multiplying, (7/8)x = 4.
Multiplying both sides by 8/7 is an easy way to isolate x:
(8/7)(7/8)x = (8/7)(4)
or
x = 32/7, or 4 4/7 meals
The area of a square garden is 98 m2. How long is the diagonal?
Answer:
The diagonal is about 14 m
Step-by-step explanation:
A = s^2
98 = s^2
so
s = √98
diagonal c^2 = 98 + 98
c^2 = 196
c = √196
c ≈ 14
Answer:
The diagonal is about 14 m
Answer:
C= 14
Step-by-step explanation:
The side is the square root of the area
S × S = A
S = √98
The diagonal is the hypotenuse of a right triangle formed by the two sides so
a² + b² = c²
Where C = the diagonal A = √98 , B = √98
so C²= (√98)² + (√98)²
This gives: C²= 98 + 98 or
C² = 196
√C² = √196
C= 14
I need a step by step explanation how to solve for the solutions of this (Not by graphing)
y=({x}^2)-8x+15 and y=3x+15 (Once again plz solve using a method other than graphing and add an explanation)
Answer:
(0, 15) and (11, 48)
Step-by-step explanation:
Given the 2 equations
y = x² - 8x + 15 → (1)
y = 3x + 15 → (2)
Substitute y = x² - 8x + 15 into (2)
x² - 8x + 15 = 3x + 15 ( subtract 3x + 15 from both sides )
x² - 11x = 0 ← in standard form
x(x - 11) = 0 ← in factored form
Equate each factor to zero and solve for x
x = 0
x - 11 = 0 ⇒ x = 11
Substitute these values into (2) for corresponding values of y
x = 0 : y = 0 + 15 = 15 ⇒ (0, 15)
x = 11 : y = 33 + 15 = 48 ⇒ (11, 48)
Solutions are (0, 15), (11, 48)

Water has a density of about 0.0361 pounds/cubic inch. You might know that wood floats on water. What can you conclude about the densities of objects that float and the densities of objects that do not?
Answer:
Step-by-step explanation:
Objects that float on water have densities less than the density of water; those that do not float on water have densisties greater than the density of water:
Float on water: d < 0.0361 lb/in³ (where d denotes denisity)
Do not float on water: d > 0.0361 lb/in³
The densities of objects that float on water are lower than those of objects that don't float.
What is density?It is defined as the mass-to-volume ratio. The density indicates the object's density and is represented by the symbol. The density is measured in kilograms per cubic meter.
We have:
Water has a density of about 0.0361 pounds/cubic inch.
Let d be the density:
Float on water: d < 0.0361 lb/in³
Do not float on water: d > 0.0361 lb/in³
The densities of objects that float on water are lower than those of objects that don't, which have densities higher than those of water.
Thus, the densities of objects that float on water are lower than those of objects that don't float.

Whether public goods should be paid for through taxes or individual fees depends on various factors, including the nature of the good and one's income level. For many public goods and services, a combination of tax funding and user fees is used. The decision between the two is a matter of public policy and individual preference.
Explanation:The decision on whether to pay for public goods through taxes or individual fees depends on various factors. In essence, this relates to the discussion on public provision versus personal pay-per-use. Some public goods, like parks, are free to use, but the government charges for certain services, such as parking or reserving picnic areas. This is a mixture of public provision at no charge along with fees for some purposes.
On the other hand, taxes are paid by most working people and by consumers when they buy goods and services. These taxes fund public services like roads, bridges, schools, and public safety functions. Thus, some may prefer public goods to be funded through taxes so everyone contributes to these community-supporting services.
Nonetheless, there are also 'toll goods', like cable TV and private schools, that are open to everyone but require users to pay a fee. The choice between taxes versus individual fees can also depend on one's income level, as those with more discretionary income might prefer pay-per-use to avoid potential higher taxes.

At a local basketball game, all tickets are the same price and all souvenirs are the same price. Mr. Smith bought 2 tickets for this basketball game and 1 souvenir for a total of $17.25. Ms. Lockhart bought 5 tickets to the same game and 2 souvenirs for a total of $42.00. How much was a ticket to this game?
*please explain!*
Answer:
The answer is $7.50.
Step-by-step explanation:
First you have to find the price of the souvenirs which were $2.25, just by doing each common price. Then you just do the answer you got divided by two.
The one ticket for this basketball game is $ 7.50, and one ticket for a souvenir is $2.25.
What is a linear equation?It is defined as the relation between two variables if we plot the graph of the linear equation we will get a straight line.
If in the linear equation one variable is present then the equation is known as the linear equation in one variable.
Let's suppose the price of the one ticket = $x
And the price of the one souvenir = $y
We have:
2x + y = 17.25 ....(1)
5x + 2y = 42.00 ....(2) (from the quetion)
From the equation (1):
y = 17.25 - 2x
Put the value of y in the equation (2), we get:
5x +2(17.25 -2x) = 42
5x + 34.5 - 4x = 42
x = 42 - 34.5
x = $ 7.50
and y = 17.25 - 2x ⇒ 17.25 - 2(7.5) ⇒ $2.25
Thus, the one ticket for this basketball game is $ 7.50, and one ticket for a souvenir is $2.25.

A circle has a circumference of 14pi. What is the area in terms of pi?
Step-by-step explanation:
Divide the circumference by pi to get diameter, which is 14. Divide 14 by 2 for the radius, which is 7. Now square the radius to get 49, and multiply by pi for the area.
Area is 49pi.
The area of the circle in terms of π with a circumference of 14π is 49π units².
Given a circle.
Also, given that:
Circumference of the circle = 14π
It is required to find the area of the circle.
It is known that:
Circumference of a circle is:
C = 2πr, where r is the radius.
So, here,
2πr = 14π
2r = 14
r = 7
So, the radius of the circle is 7.
So, the area of the circle is:
A = πr²
= π(7)²
= 49π
Hence, the area is 49π.

To integrate sec³(x), use integration by parts and trigonometric identities, ultimately resulting in the integral: 1/2 * (sec(x) * tan(x) + ln|sec(x) + tan(x)|) + C.
To integrate sec³(x), we can use integration by parts. Let’s denote the integral by I:
I = ∫ sec³(x) dx
First, we use the identity:
sec³(x) = sec(x) * sec²(x)We know that sec²(x) = 1 + tan²(x), so:
sec³(x) = sec(x) * (1 + tan²(x)) = sec(x) + sec(x) * tan²(x)Now, we use integration by parts:
Let u = sec(x) and dv = sec(x) * tan²(x) dx.Then, du = sec(x) * tan(x) dx and v = tan(x).
Using integration by parts formula ∫ u dv = uv - ∫ v du, we get:
I = ∫ sec(x) * sec²(x) dx = sec(x) * tan(x) - ∫ tan(x) * sec(x) * tan(x) dxWhich simplifies to:
I = sec(x) * tan(x) - ∫ sec(x) * tan²(x) dxWe already know sec²(x) = 1 + tan²(x), so:
tan²(x) = sec²(x) - 1∫ sec(x) * tan2(x) dx = ∫ sec(x)(sec²(x) - 1) dx = ∫ sec³(x) dx - ∫ sec(x) dxI = sec(x) * tan(x) - ∫ sec(x) * tan²(x) dx∫ sec³(x) dx = sec(x) * tan(x) - ∫ sec³(x) dx + ∫ sec(x) dx2∫ sec³(x) dx = sec(x) * tan(x) + ln|sec(x) + tan(x)| + C∫ sec³(x) dx = 1/2 * (sec(x) * tan(x) + ln|sec(x) + tan(x)|) + CPlz help accidentally checked it in

Arc UT = 50°
Now since Arc PQ is half of the diameter, then:
Arc PQ = 90°
The same applies for Arc QR
Arc QR = 90°
9. 275°
Arc UPQ = 40°+50°+180°
Arc UPQ = 275°
10. 90°
Arc UTS = 50°+40°
Arc UTS= 90°
11. 140°
Arc RSU = 50°+40°+50°
Arc RSU = 140°
12. 270°
Arc PQS = 40°+50°+180°
Arc PQS = 270°
13. 180°
Arc PQR = 90° + 90°
Arc PQR = 180°
14. 50°
15. 130°
Arc STP = 40°+50°+40°
Arc STP = 130°
16. 320°
Arc PRU = 180° + 50° + 40° + 50°
Arc PRU = 320°
