If a point is on the graph of the exponential equation then it should be true when you solve.

g(x) = (1/5)^x

y = (1/5)^x

1/125 = (1/5)^3

cbrt(1/125) = 1/5

.2 = 1/5

.2 = .2 YES

5 = (1/5)^-1

5 = 5 YES

1/25 = (1/5)^-2

-2root(1/25) = 1/5

5 = 1/5 NO

0 = (1/5)^1

0 = .2 NO

The correct answers are A and B.

This is about understanding input and output of a graph.

Correct Points are;

Option B; (-1, 5) and Option A; (3, 1/125)

x is the input value which is on the x-axis

g(x) is the output value which is on the y-axis

This will follow a coordinate writing system of (x, y)

Let us put 3 for x in the function;

y = (1/5)³

y = 1/125

y = 1/125 corresponds to y = 1/125 and so it is correct.

Option B; (-1, 5) means that when x = -1, y = 5

Let us put -1 for x in the function;

y = (1/5)⁻¹

y = 5

y = 5 corresponds to y = 5 and so it is correct.

Let us put 3 for x in the function;

y = (1/5)⁻²

y = 25

y = 1/25 doesn't correspond to y = 25 and so it is not correct.

Let us put 1 for x in the function;

y = (1/5)¹

y = 1/5

y = 0 doesn't correspond to y = 1/5 and so it is not correct.

Answer:

B) 2

Step-by-step explanation:

Given expression,

48 ÷ ((2 + 6) × 2) − 1

In simplification we follows the following order,

B = Bracket

O = Of

D = Division

M = Multiplication

A = Addition,

S = Subtraction,

Thus, steps of solving the given expression by following BODMAS are as follow,

[tex]\frac{48}{(2 + 6) \times 2}-1[/tex]

[tex]=\frac{48}{8\times 2}-1[/tex]

[tex]=\frac{48}{16}-1[/tex]

[tex]=3-1[/tex]

[tex]=2[/tex]

Hence, OPTION B is correct.

The value equivalent to 48 ÷ ((2 + 6) × 2) - 1 is B) 2.

To solve this problem, we need to follow the order of operations (also known as PEMDAS or BODMAS).

First, we calculate the expression inside the parentheses: 2 + 6 = 8.

Next, we multiply the result by 2: 8 × 2 = 16.

Finally, we divide 48 by the result: 48 ÷ 16 = 3.

After that, we subtract 1: 3 - 1 = 2.

Therefore, the value equivalent to 48 ÷ ((2 + 6) × 2) - 1 is 2.

Answer:

A

Step-by-step explanation:

74,000 x .48 = 35520. 35520 is the amount of property you have to pay for.

35520 x 0.031 = 1,101.12.  1.101.12 is the amount you owe in property tax.

The amount owed in property tax to the nearest dollar is $1,101

In real estate management, the market price is the price at which a buyer is willing to pay and which the seller is as agreed to receive at the present time.

From the parameters given:

From the property, the required amount of property to be paid for is:

Solution for (a)

Earlier Copper pennies are 22.

After 1983 pennies are 28.

Step-by-step explanation:

Pennies minted after 1983 weigh 2.50g

Earlier copper pennies weigh 3.11g

A roll of pennies contains 50 pennies.

A particular roll of pennies weighs 138.42g

Let the number of pennies minted after 1983 be x and;

Earlier copper pennies be 50 - x

2.50x + 3.11(50 - x) = 138.42

Opening the brackets gives;

2.5x + 155.5 - 3.11x = 138.42

Solving like terms together gives;

-0.61x = -17.08

Dividing through gives;

x = 28

So there are 28 after 1983 pennies and;

50 - 28 = 22 earlier pennies.

Step-by-step explanation:

The liquid height in the new cylinder will be 4 cm after the volume of liquid from the original cylinder is transferred.

In the context of this problem, we are dealing with the concept of the volume of a cylinder. The volume of a cylinder is given by the formula V=πr²h, where r is the radius of the base and h is the height of the cylinder. The given volume in the problem is 36π cm³ and the radius of the second cylinder is 3 cm. We will use the volume formula to find the height.

We know that V=36π cm³ and r=3 cm. Substituting these values into the volume formula, we get 36π=π(3)²h. Simplifying the equation gives us 36π=9πh. Dividing both sides by 9π, we arrive at the solution, h=4 cm. Therefore, the height of the liquid in the new cylinder will be 4 cm.

Answer:

x=56 and the exterior angle is 116

Step-by-step explanation:

We will call the unknown angle in the triangle y.  Angle y and the angle (2x +4) form a straight line so they make 180 degrees.

y + 2x+4 =180

Solve for y by subtracting 2x+4 from each side.

y + 2x+4 - (2x+4) =180 - (2x+4)

y = 180-2x-4

y = 176-2x

The three angles of a triangle add to 180 degrees

x+ y+ 60 = 180

x+ (176-2x)+60 = 180

Combine like terms

-x +236=180

Subtract 236 from each side

-x+236-236 = 180-236

-x = -56

Multiply each side by -1

-1*-x = -56*-1

x=56

The exterior angle is 2x+4.  Substitute x=56 into the equation.

2(56)+4

Considering  room to be in the shape of Cuboid as well as the Bed to be in the shape of Cuboid.

Dimensions of Room

Let Length of cuboid which is in the shape of room = L

Breadth of cuboid which is in the shape of  room = B

Height of cuboid which is in the shape of room = H

Considering, L>B>H

Dimension of Bed

Length=[tex]\frac{L}{6}[/tex] units

Breadth=[tex]\frac{B}{4}[/tex] units

Height=[tex]\frac{H}{6}[/tex] units

Taking one corner at origin i.e (0,0,0)

You can keep your bed at any place inside the room, but you want your bed to be at that place inside the room where the window is located so that proper ventilation and sunlight can enter your room.

Taking bed to be in the middle of room near the window and considering it's upper face

Distance from one corner i.e from length= B- [tex]\frac{B}{4}[/tex]=[tex]\frac{3B}{4}[/tex] Units

Distance from other corner=  0 Units

Distance from Breadth of one side of wall= [tex]\frac{L}{3}[/tex] units

Distance from one corner i.e from Breadth =L - [tex]\frac{L}{3}[/tex]-[tex]\frac{L}{6}[/tex]= [tex]\frac{L}{2}[/tex]

Distance from floor i.e surface=[tex]\frac{H}{6}[/tex] units

Distance from Ceiling= H -[tex]\frac{H}{6}[/tex] = [tex]\frac{5 H}{6}[/tex] units

To find the distance each bed edge should be from the corner in a scale drawing, determine the scale used (such as 1 inch = 6 feet), convert actual bed dimensions using the scale, and ensure measurements on the drawing are precise and noted with the correct line types.

To determine how far each edge of the bed should be from its own corner of the wall in a scale drawing, first establish the scale being used for the model. For example, if the scale is 1 inch = 6 feet, convert the actual dimensions of the bed into the scale size by using ratios that compare the scale distance to the actual distance. If the actual bed is 6 feet long, then the length on the scale model would be 1 inch. When recording measurements, both the actual size and the scale size should be clearly marked to prevent confusion. It is important to use correct line types and to make all the drawings to exact measurements within the constraints of the paper size.

For consistent and accurate representation, the edges of the bed should be measured from the corner of the walls based on the determined scale. This involves calculating the distance of the bed from the wall in actual size, then converting that distance to the scale model size. Pay attention to significant figures and the choice of units (inches, feet, centimeters, meters) to maintain precision in your scale drawing.

Step-by-step explanation:

We can first define the variables as hh for the number of Harry's toys on Monday and tt for the number of Teddy's toys on Monday.

We know that on Monday, Harry had 75\%75% as many toys as Teddy, so we can write the following equation:

\qquad h=0.75th=0.75t

Hint #2

When we add 3232 toys to Harry's collection, we get h+32h+32. We can also make an adjustment to Teddy's collection, as he acquired 15\%15% more. We can represent that as 1.15t1.15t, as we should add 15\%15% to 100\%100% to get a percent increase.

Now let's make an equation for Tuesday:

\qquad h+32=1.15th+32=1.15t

Hint #3

We also know that h=0.75th=0.75t from the first equation, so we can substitute that in.

\qquad 0.75t + 32 = 1.15t0.75t+32=1.15t

Let's solve by first subtracting 0.75t0.75t from both sides.

\qquad 32 = 0.4t32=0.4t

We can then divide by 0.40.4 to solve for tt, and when we do that, we find that t=80t=80.

Hint #4

Since t=80t=80, we must substitute it into another equation to find hh (the number of toys Harry had on Monday). Let's pick the first equation.

\qquad h=0.75th=0.75t

\qquad h=0.75(80) = 60h=0.75(80)=60

Hint #5

Harry had 60 toys on Monday.
