The slope of the linear function shown in the graph is of 2, as:
Run = 2.Slope = rise/run = 4/2 = 2.What is a linear function?A linear function is modeled according to the following rule:
y = mx + b
In which:
m is the slope of the function, which is the rate of change of the function, that is, the change in y divided by the change in x.b is the y-intercept of the function, which is the the value of y when the function crosses the x-axis, that is, when x = 0.For this problem, we want to find the slope given two points of the function, which are (2,4).
For the calculation, we have that:
The rise is the change in y.The run is the change in x.Hence:
The rise is of 4 - 0 = 4.The run is of 2 - 0 = 2.The slope is of 4/2 = 2.More can be learned about linear functions at https://brainly.com/question/24808124

What is the domain of the function y = square root x+6 -7?
Answer:
-6 ≤ x < ∞
Step-by-step explanation:
You want the domain of the function y = √(x+6) -7.
DomainThe domain of a function is the set of x-values for which the function is defined. On a graph, it is the horizontal extent of the graph.
The square root function is undefined for negative arguments, so that limits the domain of the given function:
x+6 ≥ 0
x ≥ -6 . . . . . domain of the given function
__
Additional comment
When the domain is written in interval notation, both the left and right ends of the interval must be specified.
[-6, ∞)
The square bracket identifies -6 as being part of the domain. The parenthesis is used with ∞, because that number has no specific value.

Yu Yan competes in a sprint triathlon. The race consists of three parts: a 0.5-mile swim, a 12.4-mile bike ride, and a 3.1-mile run. a. Yu Yan completes the swim portion of the sprint triathlon in 25 minutes. What is her average swimming speed in miles per minute?
The average swimming speed of Yu Yan is 0.02 miles per minute.
We are given that:
Yun Yan needs to swim 0.5 miles in the race.
She completed it in 25 minutes.
We need to find the average speed of Yu Yan in swimming in meter / minute.
We will do this by dividing the number of miles that she needed to swim with the number of minutes she took to complete it.
Average swimming speed = 0.5 miles / 25 minutes
Average swimming speed = 0.02 miles / minute
Therefore, the average swimming speed of Yu Yan is 0.02 miles per minute.

Charles, age 45, would like to determine how much life insurance to purchase using the human life value approach. He assumes his average annual earnings will remain at $40,000. Of this amount, $20,912 is available annually for the support of his family. Charles will generate this income for 24 more years and he believes that 5.37 percent is the appropriate interest (discount) rate. What is Charles' human life value? (Round your answer to 2 decimal places)
Using it's formula, it is found that Charles' human life value is of $26,951.39.
What is the human life value formula?The human life value formula(HLV) is given by the following multiplication:
HLV = Annual Expenses x Number of Years x Interest Rate.
For this problem, we have that:
$20,912 is available annually for the support of his family, hence the annual expenses are of $20,912.Charles will generate this income for 24 more years, hence the number of years is of 24.As stated in the problem, the interest rate is of 5.37%, hence, as a decimal, is of 0.0537.Hence, applying the formula, we have that Charles' human life value is found as follows:
HLV = 20912 x 24 x 0.0537
HLV = $26,951.39.
Charles' human life value is of $26,951.39.

If she rides for 6 more days, what is the average number of miles she would have to
ride each day to meet her goal?
Please help!
if in the next 6 days she rides an average of 8 miles per day, she will meet her goal.
What is the average number of miles she would have to ride each day to meet her goal?We know that Mayerlin wants to ride her bicycle for 56 miles this week, and she already has ridden 8 miles, so the distance left is:
56mi - 8mi = 48mi
Now, to find the average distance that she needs to ride each day in order to meet her goal, we need to take the quotient between the distance left and the number days that she has left (6 days), then we will get:
D = 48mi/6 = 8mi
This means that if in the next 6 days she rides an average of 8 miles per day, she will meet her goal.

Brody's age is 3 years less than twice Trinity's age? The sum of their ages is 30.
Answer: Brody's Age is 19 and Trinity's age is 11
Step-by-step explanation:
x = Trinity's age
2x-3= Brody's age
The sum of the ages is 30, so
x + (2x-3) = 30
3x - 3 = 30
add 3 to both sides 30 turns into 33 so,
3x = 33
divide by 3 both sides
x = 11 which is trinity's age and plug x into 2x - 3 which is 19 so that's Brody's age.

What is mathematical expression?
A mathematical expression is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Let x be the amount invested at 9% rate.
And (28000−x) be the amount invested at 2% rate.
The total annual income is $1435
Let us find the amount invested at 9% rate:
x9%+2%(28000−x)=1435
9%+2%(28000−x)=1435
0.09x+0.02(28000−x)=1435
0.09x+560−0.02x=1435
0.09x−0.02x=1435−560
0.07x=875
x=875/0.07
x=12500
Let us find the investment amount at 2% rate:
⇒28000−x

What is defined as the rectangle?A rectangle is a closed two-dimensional shape with four sides, four corners, and four right angles (90°).
A rectangle's opposite sides are equal as well as parallel. Because a rectangle is a 2-D shape, it has two dimensions: length and width. The length of the rectangle is the longer side, and the width is indeed the shorter side.Now, as per the given question;
The area of the rectangular floor is given as two hundred thirty-nine and one-fourth square feet.
Thus,
A = 239.25 feet
The width is fourteen and one-half feet.
Thus,
W = 14.5 feet
The formula for area is;
A = L×B (L is the length)
Put the values;
239.25 = L×14.5
L = 239.25/14.5
L = 16.5 feet
The rectangular perimeter is;
P = 2(L + B)
P = 2(16.5 + 14.5)
P = 62 feet
Therefore, the perimeter of the rectangle floor is found to be 62 feet.

The vertical position y (in feet) of a rock t seconds after it was dropped from a cliff is given by the formula y equals short dash -16 t squared plus 4 t plus 380. The base of the cliff corresponds to y = 0. After how many seconds will the rock hit the ground at the base of the cliff?
The seconds that it will take the rock hit the ground at the base of the cliff is 5 seconds
How to calculate the value?Based on the information given, it should be noted that the expression given is:
y = -16t² + 4t +380
We have to divide through by 4. Therefore,
y = -4t² + t + 95
y = -4t² + 20t - 19t + 95
y = -4t(t - 5) - 19(t - 5)

Ordered: 130 mg. Available: 1 gr/tablet. How many tablets should be given? ________
Answer:
2
Step-by-step explanation:
1gr=100mg
130-100=30
No tablets should be given since the ordered quantity of 130 mg is less than the available quantity per tablet of 1 g.
How many tablets should be given?We have the following data:
Ordered amount: 130 mg
Available amount per tablet: 1 g
To decide the number of tablets to be given, we have to be make sure the units are steady. Let's change over the ordered amount to grams:
130 mg = 130/1000 g = 0.13 g
Presently, we are able calculate the number of tablets:
Number of tablets = Ordered amount / Available amount per tablet
Number of tablets = 0.13 g / 1 g = 0.13 tablets
Since we cannot administer a fraction of a tablet, we round the result to the closest whole number. In this case, 0.13 is less than 0.5, so we round down:
Number of tablets to be given = tablets
Hence, no tablets ought to be given since the ordered amount of 130 mg is less than the available amount per tablet of 1 g.
