F(x)=sqrt x -4.find the inverse of f(x) and it’s domain
Answer:
B
Step-by-step explanation:
[tex]y = \sqrt{x } - 4 \\ \sqrt{x} = y + 4 \\ x = (y + 4) {}^{2} \\ [/tex]
Domain of inverse = Range of f = x>-4
Hence B
The correct option is B which is f⁻¹(x) = ( x + 4 )² and x ≥ -4.
What is an inverse function?The inverse function of a function f in mathematics is a function that reverses the operation of f. If and only if f is bijective, the inverse of f is true.
A function's range is the collection of values it can take as input. After we enter an x value, the function outputs this sequence of values.
The given function is f(x) = √x - 4. The inverse function will be calculated as:-
y = √x - 4
√x = y + 4
Squaring on both sides.
x = ( y + 4 )²
Replace x with y.
y = ( x + 4 )²
The range of the function is x ≥ -4.
Therefore, the correct option is B which is f⁻¹(x) = ( x + 4 )² and x ≥ -4.

Tele-Mart instituted a 5-for-1 split in April. After the split, Ashlee owned 1,860 shares. How many shares had she owned before the split?
Answer:
372 shares
Step-by-step explanation:
Let
x = shares owned before the split
Share after split : share before split = 5 : 1
Share after split : share before split = 1,860 : x
Equate both ratios
5 : 1 = 1,860 : x
5/1 = 1,860/x
Cross product
5 * x = 1 * 1,860
5x = 1,860
x = 1,860/5
x = 372
x = shares owned before the split = 372 shares

Ent
N= Noekt
No
= inital amount of C-14 (at time
t = 0)
N = amount of C-14 at time t
k = 0.0001
t = time, in years
Answer:
Step-by-step explanation:
I'm assuming you need the age of the bowl. Start with the fact that you have remaining 28% of the original amount before any of it decayed. You always start with 100% of something unless you're told differently. That means that the equation looks like this:
[tex]28=100e^{-.0001t}[/tex] and begin by dividing both sides by 100 to get
[tex].28=e^{-.0001t}[/tex] . To solve for t we have to be able to bring it down from its current position of exponential. To do this we would either take the log or the natural log since the rules for both are the same. However, the natural log is the inverse of e, so they undo each other. We take the natural log of both sides which allows us to pull down the -.0001t. At the same time remember that the natural log and e are inverses of each other so they are both eliminated when we do this.
ln(.28) = -.0001t Now it's easy to solve for t.
[tex]\frac{ln(.28)}{-.0001}=t[/tex] and
[tex]\frac{-1.272965676}{-.0001}=t[/tex] so
t = 12729.65676 years or rounded, 12730 years.

Sal is trying to determine which cell phone and service plan to buy for his mother. The first phone costs $100 and $55 per month for unlimited usage. The second phone costs $150 and $51 per month for unlimited usage. How many months will it take for the second phone to be less expensive than the first phone?
The inequality that will determine the number of months, x, that are required for the second phone to be less expensive is
.
The solution to the inequality is
.
Sal’s mother would have to keep the second cell phone plan for at least
months in order for it to be less expensive.
Answer:
It will take 13 months for the second phone to be less expensive than the first phone.
Step-by-step explanation:
Since Sal is trying to determine which cell phone and service plan to buy for his mother, and the first phone costs $ 100 and $ 55 per month for unlimited usage, while the second phone costs $ 150 and $ 51 per month for unlimited usage, to determine how many months will it take for the second phone to be less expensive than the first phone, the following calculation must be performed:
100 + (55 x 10) = 100 + 550 = 650
150 + (51 x 10) = 150 + 510 = 660
100 + (55 x 12) = 100 + 660 = 760
150 + (51 x 12) = 150 + 612 = 762
100 + (55 x 13) = 100 + 715 = 815
100 + (51 x 13) = 150 + 663 = 813
Therefore, it will take 13 months for the second phone to be less expensive than the first phone.
Answer:
1) 100 + 55x > 150 + 51x

What is the value of x?
O4 units
O 5 units
O 8 units
O 10 units
Answer:5 units!
Step-by-step explanation:
.
The value of x will be 5 units for the sphere that has the volume of (500/3)π cubic units.
From the formula of the volume of sphere,
volume of sphere = 4/3 πr³
where, r is the radius
in our case,
volume = (500/3)π
radius = x
substituting the given values
(500/3)π = (4/3)π *x³
x³ = 125
x= 5 units
Therefore, the value of x will be 5 units.

Hi I really need help with this question.So if you can help me thank you so much and if you can help me can you explain it step by step please and thank you so much your a life saver <3
Answer:
Step-by-step explanation:
I'll answer the question, but before I do, let me crab about the reliance on a diagram. You should never have to answer a question where you make assumptions about the diagram. It should state the the longest leg in one triangle = 2x - 4, and the hypotenuse in the larger triangle is 42, while in the smaller one it is x + 8\
Added to which you have to state that there is a ratio between the large triangle and the small one.
24/(2x - 4) = (x + 8)/42 Cross Multiply
24*42 = (x + 8)*(2x - 4) Remove the brackets. Combine the left
1008 = 2x^2 - 4x + 16x - 32 Combine the right and switch
2x^2 + 12x - 32 = 1008 Subtract 1008
2x^2 + 12x - 1040 = 0 Divide by 2
x^2 + 6x - 520 = 0
(x + 26)(x - 20) = 0
x = - 26 which has no meaning
x = 20 which is the answer.
2x - 4 = 2*20 - 4 = 36
x + 8 = 28
I'm not sure what you want -- the side lengths or just x.
Step-by-step explanation:
the ratio
24:2x-4=x+8:42
24/2x-4=x+8/42
24×42=(x+8)(2x-4)
1008=2x(x+8)-4(x+8)
1008=2x²+16x-4x-32
1008=2x²+12x-32
1008+32=2x²+12x
1040=2x²+12x
0=2x²+12x-1040
OR
24/2x-4=x+8/42
LCM=42(2x-4)
42(2x-4)×24/2x-4=42(2x-4)×x+8/42
42×24=(2x-4)(x+8)
1008=2x(x+8)-4(x+8)
1008=2x²+16x-4x-32
1008=2x²+12x-32
1008+32=2x²+12x

Find two positive numbers so that twice their sum equals their product and one number is 10 times the other number. Enter the smaller number first.
Answer:
Step-by-step explanation:
We'll call the 2 numbers x and y. Starting with the last part of that first sentence "one number is 10 times the other number" can be written, in algebraic form:
y = 10x
Now on to the first statement about the numbers: "twice their sum" is 2(x + y) and "equals their product" is = xy. Putting that all together:
2(x + y) = xy and we know that y = 10x so
2(x + 10x) = x(10x) and
[tex]2(11x)=10x^2[/tex] and
[tex]10x^2-22x=0[/tex] and
x(10x - 22) = 0 so
x = 0 or 10x - 22 = 0 which makes
x equal to [tex]\frac{22}{10}=2.2[/tex]
So x = 2.2 and y = 22.
Select the correct answer. . Which value of x makes this equation true? -12x - 2(x + 9) = 5(x + 4) ОА. 13/19 OB. -1/3 OC. -2 OD. 5
Answer:
B -1/3
Step-by-step explanation:
The value of x that makes this equation true is x = -2
Which value of x makes this equation true?We have the equation:
-12x - 2(x + 9) = 5(x + 4)
To solve it, we need to isolate x on one side of the equation:
-12x - 2x - 18 = 5x + 20
-12x - 2x - 5x = 20 + 18
-19x = 38
x = 38/-19 = -2
The value of x that makes this equation true is x = -2

Find the angle marked with the ? mark
Answer:
53 degrees
Step-by-step explanation:
Angle N = angle E
because angle made by joining end points of same chord on circumference are always equal.
so angle E = 37
Angle D = 90 ( because angle made by diameter on circumference is 90 degrees)
Now in Triangle DEC. Sum if all the angles of triangle us 180
Angle D + angle E + ? = 180
37 + 90 + ? = 180

Answer:

Step-by-step explanation:

The measure of angle B is 45° since option F. is correct in the given question.
What do we mean by supplementary angles?Any two angles (say X & Y), are said to be supplementary when their summation (X + Y) is equal to 180°.
How to determine Angle B?Angle A and Angle B are supplementary, which implies A+B=180°.
Angle B is one-third angle A, which implies
[tex]B=\frac{1}{3} A[/tex]
or, 3B = A
Using the value of A in the previous equation, we get 3B + B = 180°.
