Answer:

Option B.

Step-by-step explanation:

Inverse function:

Suppose we have a function y = f(x). To find the inverse function, we exchange x and y on the original function, and then isolate y.

The domain of the inverse function(x values) is the range of the original function(y values).

Original function:

[tex]f(x) = \sqrt{x} - 5[/tex]

Domain is [tex][0,\infty)[/tex], and when [tex]x = 0, f(x) = -5[/tex]. So the range is [tex][-5,\infty][/tex], that is, [tex]y \geq -5[/tex]

Inverse function:

[tex]y = \sqrt{x} - 5[/tex]

Exchanging x and y

[tex]x = \sqrt{y} - 5[/tex]

[tex]\sqrt{y} = x + 5[/tex]

[tex](\sqrt{y})^2 = (x+5)^2[/tex]

[tex]y = (x+5)^2[/tex]

The inverse function is [tex]f^{-1}(x) = (x+5)^2[/tex]

Domain:

Range of the original function is [tex]y \geq -5[/tex], so the domain of the inverse function is [tex]x \geq -5[/tex]. The correct answer is given by option B.

Answer:

B. f ^ -1 (x) = (x + 5) ^ 2;

x > -5

Answer:

[tex]\cos(W) = \frac{9}{41}[/tex]

Step-by-step explanation:

Given

[tex]\angle Y = 90^o[/tex]

[tex]YX = 40; XW = 41; WY = 9[/tex]

Required

Determine [tex]\cos(W)[/tex]

The question is illustrated with the attached image.

So:

[tex]\cos(W) = \frac{Adajacent}{Hypotenuse}[/tex]

[tex]\cos(W) = \frac{WY}{XW}[/tex]

This gives:

[tex]\cos(W) = \frac{9}{41}[/tex]

Answer: 3/6 and 5/6

Step-by-step explanation:

Answer:

[tex] \frac{2}{5} [/tex]

Step-by-step explanation:

The probability of event A happening is denoted by P(A). The probability of event A happening is given by the formula below:

[tex]\boxed{P(A) = \frac{number \: of \: favourable \: outcomes \: in \: A}{total \: possible \: outcomes}} [/tex]

Since there are 2 black pens, and only one pen is chosen, the number of favourable outcomes in choosing a black pen is 2.

The total possible outcomes is the total number of pens in this case.

P(black pen)

[tex] = \frac{2}{2 + 2 + 1} [/tex]

[tex] = \frac{2}{5} [/tex]

This is the theoretical probability as it is not determined from experimental results.

Answer: 130 ft^2

Step-by-step explanation:

Area= 2(wl+hl+hw)

Area= 2(5•10+1•10+1•5)

Area= 2(50+10+5)

Area= 2(65)

Area= 130

Answer:

The surface area is 130 square feet.

Step-by-step explanation:

A = 2(wl + hl + hw)

2 · (5 · 10 + 1 · 10 + 1 · 5)

130

Answer:

True

Equivalent fractions are fractions with different numbers representing the same part of a whole.

Answer:

y = 5x - 6

Step-by-step explanation:

y - 9 = 5 ( x - 3 )

y = 5x - 15 + 9

Have a great day!

The net below represents a container. What solid figure does it show?

We can see that the given net has 12 edges, 6 faces and 8 vertices if we compile it up. These number of edges, faces and vertices are found in a cuboid or a rectangular prism. With this we can conclude that if we compile the given net, it will form a cuboid or a rectangular prism. So, the given net is of a cuboid or a rectangular prism.

The given net is of a cuboid or a rectangular prism.

Answer:

one solution = 3

Step-by-step explanation:

Let's solve your equation step-by-step.

5x+17=4(3x−1)

Step 1: Simplify both sides of the equation.

5x+17=4(3x−1)

5x+17=(4)(3x)+(4)(−1)(Distribute)

5x+17=12x+−4

5x+17=12x−4

Step 2: Subtract 12x from both sides.

5x+17−12x=12x−4−12x

−7x+17=−4

Step 3: Subtract 17 from both sides.

−7x+17−17=−4−17

−7x=−21

Step 4: Divide both sides by -7

-7x/-7 = -21/-7 = 3

Answer:

D.

Step-by-step explanation:

its a right triangle, so we can use the pythagorean theorem to find h

(pythagorean theorem is a^2+b^2=c^2, c is the hypotenuse)

h^2+4^2=13^2

h^2+16=169

h^2=153

h=sqrt153

h≈ 12.4ft

Answer:

B) 1

Step-by-step explanation:

x+1/2(x-4)=1/2x+6(x-2)

x+1/2x-4/2=1/2x+6x-12

x+1/2x-1/2x-2=6x-12

x-2=6x-12

x-6x-2=-12

-5x-2=-12

-5x=-12+2

-5x=-10

5x=10

x=10/5

x=2

Answer:45

Step-by-step explanation:

There are 3 even numbers out of A total of 8 numbers.

Each spin would have a 3/8 chance of landing in an even number.

Multiply the chance of landing on even by number of spins:

120 x 3/8 = 360/8 = 45

The answer would be 45 times.

Answer:

Step-by-step explanation:

Answer: 19 years

Step-by-step explanation:

Given

Amount invested [tex]\$400[/tex]

Rate of interest [tex]R=6\%[/tex]

after 1-year amount becomes

[tex]A=400\left (1+6\%\right)\\A=400\left (1+0.06\right)\\A=400\times 1.06\\A=\$424[/tex]

After n years it is

[tex]A=400\left (1.06\right)^n[/tex]

Sum accumulated is [tex]\$1200[/tex]

[tex]\Rightarrow 1200=400\left(1.06\right)^n\\\Rightarrow 3=\left(1.06\right)^n\\\text{Taking log both sides}\\\Rightarrow n=\dfrac{\ln 3}{\ln 1.06}\\\\\Rightarrow n=18.85\approx 19\ \text{years}[/tex]
