Write an exponential function y = a(b)" whose graph passes through the given
points,
(-1,2),(2,54)

Answers

Answer 1

Answer:

y = 6 * 3ˣ

Step-by-step explanation:

y = a * bˣ

(-1 , 2):   2 = a * (b)⁻¹ = a/b               a = 2b

(2 , 54)  54 = a * b²  = 2b * b² = 2b³

b³ = 54/2 = 27          b = 3

a = 6

Function: y = 6 * 3ˣ

Find the outlier of the set of data: 20, 23, 19, 25, 4, 18, 26

Answers

What is the outlier?

Outlier can be defined as

The outlier of the dataset 20, 23, 19, 25, 4, 18, 26 is 4

How to determine the outlier?

The set of data is given as:

20, 23, 19, 25, 4, 18, 26

The outlier of the set of data is a data element that is relatively far from other data elements

In 20, 23, 19, 25, 4, 18, 26, the number 4 is relatively far from other data elements

This means that 4 is an outlier of the dataset

Hence, the outlier of the dataset 20, 23, 19, 25, 4, 18, 26 is 4

For all of the graphs:

Start the point on the number that I got from the inequality.

A filled circle means:

Greater than or equal to or less than or equal depending on where the line goes.

A hallow circle means:

Greater than or less than also depending on where the line is pointed towards too.

In order to graph an inequality you have to find and simply first then graph it.

For example on number 1, K ≤ -4.

Let's graph!

As you can see I filled in the circle and started at the point, -4.

Once I did it I made it bold from -4 and there on to the left. Making -4 be greater than or equal to K.

I showed that -4 is greater than or equal to K by making the line bold behind -4, also by filling in the circle.

There are 24 girls in a class. The ratio of girls to boys is 3:8.
How many boys are in the class?​

Answers

Answer:

64 boys.

Step-by-step explanation:

There are 3 girls for every 8 boys.

24/3 = 8

8 * 8 = 64

The number of boys will be [tex]64[/tex] .

What is ratio ?

Ratio is the comparison of two numbers i.e. how much a number contains other.

We have,

Number of girls [tex]=24[/tex]

Ratio of girls to boys [tex]=\ 3:8[/tex]

So,

According to the question,

Let number of girls [tex]=3x[/tex]

Number of boys [tex]=8x[/tex]

And,

We have number of girls so compare them,

i.e. [tex]3x=24[/tex]

⇒[tex]x= 8[/tex]

So, now putting value of [tex]x[/tex] in Number of boys,

i.e.

Number of boys [tex]=8x[/tex]

                           [tex]=8*8[/tex]

Number of boys [tex]=64[/tex]

Hence, we can say that the number of boys will be [tex]64[/tex] .

The following function represents the value of a truck, in dollars, after x years:

f(x) = 29,000(0.88)x

What does 0.88 represent?

The decrease in the value of the truck, which is 12%
The present value of the truck
The value of the truck after x years
The decrease in the value of the truck, which is 88%

Answers

Answer:

The increase in the value of the truck, which is 88%

Step-by-step explanation:

Depreciation can be defined as the reduction of cost of a fixed asset systematically until the value of the asset becomes zero.

Rate of return can be defined as the percentage of interest or dividends earned on money that is invested.

In Financial accounting, a return refers to the amount of profit generated by an investor on an investment over a specific period of time.

Basically, the rate of return which is typically expressed as a percentage of the initial costs of an investment can either be a gain or a loss on an investment. Therefore, a positive rate of return on an investment over a specific period of time, simply means that an investor is making a profit (gains) while a negative rate of return on an investment over a specific period of time, indicates that the investor is running at a loss.

Given the following function;

f(x) = 29,000(0.88)x

Where;

x is the number of years.

We can deduce from the function, that the rate at which the truck is appreciating is 88% (0.88).

Assuming x = 3

f(3) = 29,000(0.88)*3

f(3) = $76,560

Answer:

The decrease in the value of the truck, which is 12%

Step-by-step explanation:

If the decrease in the value of the truck was 88%, then the percentage would be 0.12. So therefore, since 1.00 - 0.12 is 0.88, the decrease in the value of the truck would be 12%.

Answers

Answer:

The electric field experienced by the charge is 1.248 x 10¹⁹ N/C

Step-by-step explanation:

Given;

the magnitude of the force, F = 2 N

the magnitude of the charge, q = 1.602 x 10⁻¹⁹ C

The electric field experienced by the charge is calculated as follows;

[tex]E = \frac{F}{q} \\\\E = \frac{2}{1.602 \times 10^{-19} \ } \\\\E = 1.248 \times 10^{19} \ N/C[/tex]

Therefore, the electric field experienced by the charge is 1.248 x 10¹⁹ N/C.
