The domain of the heart rate function h(t) for a runner who completed a 10-mile run in 112 minutes is [0, 112] in interval notation.
Explanation:In this scenario, the domain of the function h(t) is the time duration during which the runner is running. Thus, since the runner completed the 10-mile run in 112 minutes, the domain is from 0 (the start of the run) to 112 (the end of the run). We represent this in interval notation as [0, 112]. The square brackets indicate that the endpoints are included in the domain. So, the domain of the function h(t) in this context is [0, 112].

What is the equation that represents the line that passes through the point (2,6) and has a slope of -5?
Answer:
y = - 5x + 16
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = - 5, thus
y = - 5x + c ← is the partial equation of the line
To find c substitute (2, 6) into the partial equation
6 = - 10 + c ⇒ c = 6 + 10 = 16
y = - 5x + 16 ← equation of line

an=an-1₋(.25);a₁=192
an=192(.25)^n-1
7.32421875*10^−4
Step-by-step explanation:
Answer:
The sequence shown is geometric
Recursive function:
[tex]a_{n} = a_{n-1}\times r[/tex]
with [tex]a_1 = 192[/tex]
Explicit function: [tex]a_n = 192 \times 0.25^{n-1} [/tex]
10th term: 0.000732421876
Step-by-step explanation:
In a geometric sequence the n+1 term divide by the n term is constant
48/192 = 0.25
12/48 = 0.25
3/12 = 0.25
From this result we can deduce the recursive function:
[tex]a_{n} = a_{n-1}\times r[/tex]
with [tex]a_1 = 192[/tex]
Explicit function:
[tex]a_n = a \times r^{n-1} [/tex]
where a is the first term in the sequence (= 192) and r is the common ratio (= 0.25). Replacing:
[tex]a_n = 192 \times 0.25^{n-1} [/tex]
The 10th term is:
[tex]a_{10} = 192 \times 0.25^9 = 0.000732421876 [/tex]

Karen had a roll of ribbon 48 1/2 metres long. How many pieces of ribbon of length 1 1/5m can she cut from the roll? How many metres of ribbon will be left?
Answer:
40 and 0.5
Step-by-step explanation:
48 and 1/2 metres = 48.5 metres
1 and 1/5 metres = 1.2 metres
Take 48.5 and divide it by 1.2 and you will get 40.41666667...
Since the maximum whole number you can get is 40, you can cut 40 pieces of 1.2 metres of ribbon off.
Remainder = 48.5 - (40 x 1.2) = 0.5 metres left
The number of pieces of ribbon can be cut from roll is 40 and 0.5 m of ribbon left.
What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
We have,
Karen had a roll of ribbon 48 1/2 m long.
= 48.5 m long
and, 1 and 1/5 m = 1.2 m
Now, the number of pieces of ribbon can be cut from roll is
= (48.5) / (1.2)
= 40.416
and, the amount of ribbon left
= 48.5 - (40 x 1.2)
= 0.5 m

Rearrange to make x the subject
a = 7x/k -r
Help me pls
Final answer:
To make x the subject of the equation a = 7x/k - r, add r to both sides, multiply by k, and then divide by 7, resulting in x = k(a + r)/7.
Explanation:
To rearrange the equation a = 7x/k - r to make x the subject, we need to perform a series of algebraic manipulations. Firstly, we add r to both sides of the equation, giving us a + r = 7x/k. Following this, we multiply both sides by k to get rid of the denominator, which results in k(a + r) = 7x. Finally, we divide both sides by 7 to solve for x, which gives us x = k(a + r)/7. This rearrangement shows x as the subject of the original equation.
Xan will cover some of this box in wrapping paper. He plans to leave one of the largest faces uncovered.
12 cm
10 cm
11 cm
How much wrapping paper will Xan need?
592 square cm
614 square cm
724 square cm
808 square cm
Final answer:
To find the wrapping paper needed for a box with given dimensions and one largest face uncovered, calculate the total surface area, subtract the area of the largest face, resulting in 592 square cm of wrapping paper required.
Explanation:
The question concerns calculating the amount of wrapping paper required to cover a box while leaving one of the largest faces uncovered. Given the dimensions of the box are 12 cm, 10 cm, and 11 cm, we can calculate the surface area of each face and sum them up, excluding one of the largest face, which is one with dimensions 12 cm x 11 cm.
First, calculate the surface area of all the faces: 2(12cm x 10cm) + 2(12cm x 11cm) + 2(10cm x 11cm) = 240cm² + 264cm² + 220cm² = 724cm².Next, subtract the area of the largest face (which will not be covered): 12cm x 11cm = 132cm².Finally, subtract this area from the total surface area calculated: 724cm² - 132cm² = 592cm².Therefore, Xan will need 592 square cm of wrapping paper to cover the box while leaving one of the largest faces uncovered.

Explain the meaning of g (f(x)). Evaluate g (f(75)). d. Does g(f(x))=f(g(x)).
Answer:
See explanation
Step-by-step explanation:
A. Let x represent the original test scores.
(1) The teacher will give a 10-point bonus, then the score will be x + 10. Hence,
[tex]f(x)=x+10[/tex]
(2) The teacher will increase everyone's grade by 9% of their score, then the score will be x + 0.09x = 1.09x. Hence,
[tex]g(x)=1.09x[/tex]
B. If [tex]f(x)=x+10[/tex] and [tex]g(x)=1.09x,[/tex] then
[tex]f(g(x))=g(x)+10=1.09x+10[/tex]
Meaning: the teacher increased by 9% the score and then increased the result by 10 points.
[tex]f(g(75))=1.09\cdot 75+10=91.75[/tex]
C. If [tex]f(x)=x+10[/tex] and [tex]g(x)=1.09x,[/tex] then
[tex]g(f(x))=1.09f(x)=1.09(x+10)[/tex]
Meaning: the teacher increased by 10 points the score and then increased the result by 9%.

The required solution is -63/4.
It is required to find the number.
What is arithmetic?The branch of mathematics dealing with the properties and manipulation of numbers. a science that deals with the addition, subtraction, multiplication, and division of numbers. Fractions, decimals, percentages, fractions, square root, exponents, and other arithmetic operations are used to achieve mathematical simplifications
Given :
Step 1: Write down the question as an algebra problem, with the unknown as X
The unknown is a number plus 17, so we write it as (X+17). The product is four times (X+17), so we write it as 4(X+17). Set it equal to 5, as per the question,
4(X+17)=5
Step 2: Divide both sides by 4
4(X+17)/4=5/4
X+17=5/4
Step 3: Isolate X by subtracting 17 from both sides
X= 5/4-17
X= 5/4- (17*4)/4
X= 5/4-68/4
X=-63/4

Four speed skaters, Marco, Naim, Oliver, and Pedro, compete in a relay race where they all agree that Naim will be the last
skater. Then, they try to decide whether or not Oliver should be the first skater in the race.
Which subset, A, of the sample space shows the complement of the event in which Oliver is the first skater in the race?
A = {MOPN, PMON}
A = {OPMN, OMPN)
A = {MOPN,MPON, OPMN, POMN)
A = {MOPN. MPON, PMON, POMN)
Answer:
A = {MOPN, MPON, PMON, POMN}
Step-by-step explanation:
Everyone has already agreed that Naim would be the last skater, so we have to make sure that the result has 'N' in each last place. As we can see, they all have this.
Now, we also have to make sure Oliver not first, because although they're trying to decide, the problem asks for the complement in which "Oliver is the first skater in the race."
A complement is all the values that are NOT in the set, so it cannot be A = {OPMN, OMPN) or A = {MOPN,MPON, OPMN, POMN), because they both have at least one case where 'O' is first.
A complement is ALL other values of the set, so it cannot be A = {MOPN, PMON}, because that set only shows two possible values.
Therefore, A = {MOPN, MPON, PMON, POMN} is your answer.
Answer:A=OPMN,OMPN
Step-by-step explanation:
