evaluate the function f(x) = square root of x at given value

Answer:

No

Step-by-step explanation:

The x-value of 2 maps onto two values of y, 3 and 4, meaning the relation is not a function.

If you contribute $400 every quarter for 20 years, the amount of  interest you would  earn during the 20 years is $22,447.52

What future value formula is applicable in this case?

The applicable future value formula is that of an ordinary annuity which determines the future worth of $400 quarterly savings for 20 years bearing in mind that the quarterly interest rate is the annual interest rate divided by 4

FV=PMT*(1+r)^N-1/r

FV=worth of the annuity after 20 years=unknown

PMT=quarterly deposit=$400

r=quarterly interest rate=5%/4=1.25%

N=number of quarterly savings in 20 years=20*4=80

FV=$400*(1+0.0125)^80-1/0.0125

FV=$54,447.52

interest=$54,447.52-($400*80)

interest=$ 22,447.52

The value of 4 gal 6 qt 112 oz expressed in standard notation is; 6.375

Standard notation of a number is defined as when a number is written with only number digits. This is the typical way to write numbers since words are not used in standard number notation.

Now, from conversions, we know that;

1 oz = 0.0078125 gallons

1 qt = 0.25 gallons

Thus, 4 gal 6 qt 112 oz expressed in gallons is;

4 + (6 * 0.25) + (112 * 0.0078125)

= 4 + 1.5 + 0.875

= 6.375

Using proportions, it is found that the exact value of 41% of 379 is of 155.

A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures.

The proportion of 41% of 379 is given as follows:

0.41 x 379 = 155.39.

Since 0.39 < 0.5, the exact value is rounded to 155.

Answer: total household present are 136

Step-by-step explanation:

Given:

82.1% of Cincinnati households have a computer.

111.804 households in Cincinnati have a computer.

According to ratio and proportions we have:

let total number of houses be x;

then

(111.804/x)*100=percentage of Cincinnati households having  a computer.    [[tex]gain/total*100 =gain %[/tex]]

then

(111.804/x)*100=82.1

cross multiplying we have

x=(111.804*100)/82.1

x=136 households  (Round to the nearest whole number.)

so total household present are 136

Answer:

Movie duration:1.5hrs

Answer:

38.13 m²

Step-by-step explanation:

area of triangle = 1/2 base × height

                          = 1/2 × 4 × 3

                          = 6 m²

Area of rectangle = length ×  width

                             = 6 × 3

                             = 18m²

Area of semi circle = 180/360 × π × radius²

                               = 180/360 × 3.14 × 3²

                               = 14.13 m²

Add all the areas together

6 + 18 + 14.13 = 38.13

The estimation of the value is A. 40000.

Based on the information, we are to estimate the sum by rounding to the nearest ten thousand. 18,789 + 19,019.

It should be noted that 18789 to the nearest ten thousand is 20000.

Also, 19019 to the nearest ten thousand will be 20000.

Therefore, the addition will be:

Answer:

(9c) - 4=5

Step-by-step explanation:

Product means 'The answer when you multiply' So we are working in multiplication. ( x )

9c is the multiplication.

It says 'less' which means subtracting to our answer. So we subtract 4. So far our equation is: (9c) - 4 (Brackets are needed as we are multiplying 9 by c and not multiplying 9 by c - 4)

Lastly, it says the answer must be 5 so we add that at the end. So the answer is:

(9c) - 4=5

Answer:

300 and 30 respectively

Step-by-step explanation:

The 3 in each number can be valued at 3 with the same number of 0s as there are digits to the right of the 3.

For example, in 6300, the 3 stands for 300 because there are two digits (0 and 0) to the right of 3. So we know 3 stands for 300 because we add two 0s to the right of 3.

The segment bisector of line segment XY is line n.

The length of the line segment XY is 6 units.

A line segment is a section of a line with two endpoints. A line segment, unlike a line, has a fixed length.

As per the given diagram in the question.

It is clear that the line segment XY is being divided by another line named n.

Thus,

The two segment of the line segment XY must be equal.

XM = MY

Substitute the values from the diagram;

5x + 8 = 9x + 12

Simplifying;

4x = -4

x = -1

Put the values in each segment;

XM = 5x + 8

XM = 5(-1) + 8

XM = 3 units.

Put the value in MY

MY = 9x + 12

MY = 9(-1) + 12

MY = 3 units.

As, it is clear from above values that the both segment are equal of 3 units each.

XY = XM + MY

XY = 3 + 3 = 6

Therefore, the value of XY is 6 units.

The set X is convex.

In geometry, a subset of an affine space over the real numbers, or more broadly a subset of a Euclidean space, is said to be convex if it contains the entire line segment connecting any two points in the subset. A solid cube is an example of a convex set, whereas anything hollow or with an indent, such as a crescent shape, is not. Alternatively, a convex region is a subset that crosses every line into a single line segment.

b)The set X is convex as any two points on the set X is included in the whole set as x>0. So a line joining any two points on the set X is completely inside the set x.

c)set X is not a closed set as the compliment of the set is not an open set.

d)Set X is not bounded. If a set S contains both upper and lower bounds, it is said to be bounded. A set of real numbers is therefore said to be bounded if it fits inside a defined range. hence set x is not bounded.

Using translation concepts, the new location after the jump will be at (9,9).

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s definition or in it’s domain. Examples are shift left/right or bottom/up, vertical or horizontal stretching or compression, and reflections over the x-axis or the y-axis.

The translation rule for this problem is:

(x,y) -> (x + 4, y + 9).

Which means that the coordinates move 4 units right and 9 units up.

The initial position is:

(5,0).

Hence the final position is:

(5,0) -> (5 + 4, 0 + 9) = (9,9).

The new location after the jump will be at (9,9).
