Matilda has been studying exponential functions in her algebra class and has started to notice a pattern.

For some exponential functions, when she plugs in larger and larger numbers, she gets larger and larger numbers. For others, she gets smaller and smaller numbers. And for some, plugging in larger and larger numbers actually gets her closer and closer to one number.

Which of the following exponential functions get closer and closer to one value as you plug-in larger and larger values for x?

Select one:
A. f(x)=(34)^x+9
B. f(x)=0.45(1.9)^x
C. f(x)=(65)^x−6
D. f(x)=−7(2)^x

Answer:

5 miles

Step-by-step explanation:

1. we have to figure out how many miles of the total 43 miles victor rides to and from school by subtracting the product of five days worth of soccer practice trips from the total miles per school week but that will give us one weeks worth of school trips, so we need to divide to find how long is one days worth.

2. we know victor goes to soccer and back every school day and its a 3.6 mile round trip so we have to multiply 3.6 by 5 because thats how many days are in a week which gives us 18.

3. next, we have to subtract our product (18) from our overall mileage (43) so the equation is: 43 - 18 = x (x being the trip to school and back) giving us 25.

4. the last step is we have to divide 25 by 5 because that subtraction just gave us the entire weeks' worth of biking to school and back, we just want one day. so we will divide and get 5. victor's round trip distance to and from school is 5 miles.

Answer:

The equation that represents a proportional relationship, or a line, is y=kx, where k is the constant of proportionality. Use k=yx from either a table or a graph to find k and create the equation.

Step-by-step explanation:

I don't know if this helps!

The solution is,

The equation that represents a proportional relationship, or a line, is y=kx, where k is the constant of proportionality. Use k=yx from either a table or a graph to find k and create the equation.

Function, in mathematics, an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable.

here, we have,

given that,

we have to Complete the explanation of how you can use a table of values, an equation, and a graph to determine whether a function represents a proportional relationship.

now, we know,

The equation that represents a proportional relationship, or a line, is y=kx,

where k is the constant of proportionality.

Use k=yx from either a table or a graph to find k and create the equation.

Answer: C

Step-by-step explanation:

For [tex]4(3x - y)[/tex], you must distribute the [tex]4[/tex] to each element within the parenthesis:

[tex]4 * 3x + 4 * (-y)[/tex]

[tex]12x + (-4y)[/tex]

[tex]12x - 4y[/tex]

Answer:

C

Step-by-step explanation:

Equivalent means equal.

For A: 3x + 2y and 3(x + 2y) are not equivalent because if you distribute 3 in the second expression then it'll be 3x + 6y which is not equal to 3x + 2y

For B: 32 + 16y and 8(4 + 16y) Again if you distribute the 8 in the second expression it won't be equal to the first one

For D: -2(x - y) and -2x - 2y are not equivalent because when you distribute the -2 with the -y in the first expression then it will be 2y not -2y

C is the only option that makes sense.

Answer:

the figure on the top left

Step-by-step explanation:

Hey There!

If figure a was going to be dilated by a scale factor of 3 you would have to multiply all of its dimensions by 3

the top length would be 6

the bottom length would be 9

the right side length would be 12

and the left side length would be 9

The first figure has all of these dimensions thus it is correct answer

Answer:

$10

Step-by-step explanation:

Take the $4 that the company spends per phone case and multiply it by 2.5 which represents the 250% markup, and the result is $10

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

The original price is:

100% = $4

New price:

250% = 250% x 4 =

The cost of the phone case after the 250% markup is $10.

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

50% = 50/100 = 1/2

25% = 25/100 = 1/4

20% = 20/100 = 1/5

We have,

The original cost of the phone case = $4

Percentage markup = 250%

We can consider that the phone case's original price is 100%.

Now we need to find the price at a markup of 250%.

The cost of the phone case after the markup percentage.

= 250% of 4

= 250/100 x 4

= 5/2 x 4

= 5 x 2

= $10

Thus,

The cost of the phone case after the 250% markup is $10.

Answer:

4 on top three on bottom?

Step-by-step explanation:

Answer:

Hate to break it to you, but it actually is 3

Step-by-step explanation:

You need to make sure 3/4 is equal to the fraction.

It doesn't matter how many slots there are.

The fraction that it's going to be equal to is 9/12

To get the 12 on the bottom, you need to multiply the 4 by 3

Because you want to get an equivalent expression, you have to the same thing to the top.  So 3 x 3 is 9.

Both slots are going to have a 3 in it

Step-by-step explanation:

The cost of construction the box is Rs.7795200.

Step-by-step explanation:

Given : A cuboid of length 400 cm, Breadth 220 cm and Height 120 cm is to be made with wood costing Rs.24 per.sq.m.

To find : The cost of construction the box ?

Solution :

A cuboid of length 400 cm, Breadth 220 cm and Height 120 cm.

The total surface area of the cuboid is

TSA=2 (lb+bh+hl)TSA=2(lb+bh+hl)

Substitute the values,

TSA=2 (400\times 220+220\times 120+120\times 400)TSA=2(400×220+220×120+120×400)

TSA=2 (88000+26400+48000)TSA=2(88000+26400+48000)

TSA=2 (162400)TSA=2(162400)

TSA=324800\ cm^2TSA=324800 cm

2

Wood costing Rs.24 per.sq.m.

The cost of box constructed is

C=324800\times 24C=324800×24

C=Rs.7795200C=Rs.7795200

Therefore, the cost of construction the box is Rs.7795200.
