Step-by-step explanation:

The product of the numerical expressions 4.56 and 1000 will be given as 4560.

It is also known as the product. If the object n is given to m times then we just simply multiply them.

The numbers are 4.56 and 1000

Then the product of these two numbers will be

→ 4.56 × 1000

→ 4560

Given that,

[tex]f(x) = \sqrt{x-3}[/tex]

To find,

The domain of f(x).

Solution,

We have, [tex]f(x) = \sqrt{x-3}[/tex]

To find domain,

The term under the square root must be positive or null as follows :

[tex]x-3\ge 0[/tex]

Adding 3 both sides

[tex]x-3+3\ge 0+3\\\\x\ge 3[/tex]

So, the domain is x-3>0 .

Answer:

The cost of one rose is $11., and the cost of one geranium is $5.

Step-by-step explanation:

The cost of one rose bush and one geranium can be determined by the use of simultaneous equation. Let the cost of a rose bush be represented by x, and the cost of one geranium by y.

So that,

13x + y = 148 .............. 1

9x + 14 y = 169 ............... 2

From eqaution 1,

y = 148 - 13x ............... 3

substitute the value of y in equation 2

9x + 14(148 - 13x) = 169

9x + 2072 - 182x = 169

2072 - 169 = 182x - 9x

1903 = 173x

x = [tex]\frac{1903}{173}[/tex]

  = 11

x = 11

substitute the value of x in equation 3

y = 148 - 13x

  = 148 - 13(11)

  = 148 - 143

y = 5

x = 11, y = 5

Thus, the cost of one rose is $11., and the cost of one geranium is $5.

Answer:

Percentage: 115%

Decimal: 1.15

Fraction: [tex]\frac{23}{20}\\[/tex]

Step-by-step explanation:

Percentages, Fractions, and Decimals

Assume we set 100% as the original price of the food that Michael consumed. When he leaves a 15% tip for the waitress, he is really paying 100%+15%=115% of the original price.

Now we express 115% as a decimal, simply dividing by 100:

115% = 115/100 = 1.15

To express it as a fraction, we simplify the division instead of calculating it:

115% = [tex]\frac{115}{100}[/tex]

Simplifying by 5:

115% = [tex]\frac{23}{20}[/tex]

Answer:

  7. c(n) = 10 +2(n -1)

  8. c(20) = 48

Step-by-step explanation:

7. Your arithmetic sequence has first term a1=10 and constant difference d=2. The explicit formula for terms of an arithmetic sequence is ...

  an = a1 +d(n -1)

If we use c(n) as the function name for the function giving the number of chairs in row n, then we can fill in the numbers we know to get ...

  c(n) = 10 + 2(n -1)

__

8. Evaluating the function when n=20, we find ...

  c(20) = 10 +2(10-1) = 10 +2·19 = 10 +38

  c(20) = 48

There are 48 chairs in row 20.

Step-by-step explanation:

Boreal forests are characterized by needle-leaved, drought tolerant, evergreen trees, and a climate consisting of long, cold winters and short, cool summers.

Given:

The point is located at (-1,-4).

Point T is reflected over the x-axis to create point T′.

Point T′ is then reflected over the y-axis to create point T′′.

To find:

The ordered pair describes the location of T''.

Solution:

We have, the given point T(-1,-4).

Point T is reflected over the x-axis to create point T′. So, the rule of reflection is

[tex](x,y)\to (x,-y)[/tex]

[tex]T(-1,-4)\to T'(-1,4)[/tex]

Point T′ is then reflected over the y-axis to create point T′′. So, the rule of reflection is

[tex](x,y)\to (-x,y)[/tex]

[tex]T'(-1,4)\to T''(1,4)[/tex]

Therefore, the ordered pair (1,4) escribes the location of T′′.

Answer:

(- 1, - 3 )

Step-by-step explanation:

Given endpoints (x₁, y₁ ) and (x₂, y₂ ) partitioned in the ratio m : n

Then using the Section formula the coordinates of the point are

( [tex]\frac{nx_{1}+mx_{2} }{m+n}[/tex], [tex]\frac{ny_{1}+my_{2} }{m+n}[/tex] )

Here (x₁, y₁ ) = (- 4, - 9), (x₂, y₂ ) = (1, 1) and m : n = 3 : 2 , then

( [tex]\frac{2(-4)+3(1)}{3+2}[/tex] , [tex]\frac{2(-9)+3(1)}{3+2}[/tex] )

= ( [tex]\frac{x}{y} \frac{-8+3}{5}[/tex], [tex]\frac{-18+3}{5}[/tex] )

Answer:

D. 3-5

Step-by-step explanation:

Absolute Value

[tex] |a| = a \\ | - a| = a[/tex]

Given where a-term is greater or equal to 0.

Example

[tex] |1| = 1 \\ | - 1| = 1 \\ | - 20| = 20[/tex]

Back to the question, we evaluate the absolute value of 3-5.

[tex] |3 - 5| \\ | - 2| [/tex]

Any negative real numbers in absolute will become positive real numbers.

Therefore, our answer is —

[tex]2[/tex]

Consider all choices.

[tex] |5 - 3| = |2| = 2 \\ |3 - 5| = | - 2| = 2 \\ 5 - 3 = 2 \\ 3 - 5 = - 2[/tex]

The only answer that is different is the last choice, 3-5 = -2

Answer:

The larger angle is 54°

Step-by-step explanation:

Given

Let the angles be: θ and α where

θ > α

Sum = 72

α : θ = 1 : 3

Required

Determine the larger angle

First, we get the proportion of the larger angle (from the ratio)

The sum of the ratio is 1 + 3 = 4

So, the proportion of the larger angle is ¾.

Its value is then calculated as:.

θ = Proportion * Sum

θ = ¾ * 72°

θ = 3 * 18°

θ = 54°

Answer:

6 minutes

Step-by-step explanation:

Given

Leo = 36 sec / rev

Stan = 40 sec/rev

Required

Determine the time (in minutes) they'll meet again

We start by getting the multiples of 36 and 40 uptil we get a common multiple.

Leo: 36 = 36, 72, 108, 144, 180, 216, 252, 288, 324, 360, .....

Stan: 40 = 40, 80, 120, 160, 200, 240, 280, 320, 360....

From above, the common multiple is:

Common Multiple = 360

This means that they'll meet at 360 seconds

Convert to minutes

360 sec = 360/60 mins

360 Seca = 6 mins

Hence,it will take them 6 minutes to meet again at the starting point

Answer:

Ray CA

Step-by-step explanation:

There is a point in-between.

A ray cannot depict CA because it extends from both of its ends.

Option 2 is correct.

In mathematics, a ray is a segment of a line with a fixed starting point but no ending. That can go on forever in a single direction. A ray cannot be measured since it has no end point.

Point: Point is a dot or vertex of any figure or diagram. It represents by capital alphabet. So, B would be a point.

Line: A line is a straight path with both endless. It means we can extends line from both end. But in case of BD we can't extend from point B. So, it won't be a line.

Ray: A ray is a straight path with one endless. It means we can't extend line from one end and extend from another end. But we can extend AC from both end. It won't be a ray.

Line Segment: A line segment is a straight path with end from both end. We can't extend from either end of the line. We can say CD would be line segment.

CA cannot be represented by a ray, as it's extending from both of its ends.
