Given that,
An egg takes 198 seconds to boil a perfect egg has an altitude of -418 m.
Also it takes 209 seconds at an altitude of 8848 m.
To find,
The domain of T.
Solution,
Domain is the set of input values for which the function is defined. The least value is -418 m and the highest value is 8848 m. So, the domain is :

Carla is going on a boat tour. The boat will travel a total distance of 40 kilometers during the 10 hour tour. If the boat travels at a constant speed during the tour, what distance in kilometers should the boat travel in 7 hours? Choose the correct answer below.
Answer:
Distance cover in 7 hour = 28 kilometer
Step-by-step explanation:
Given:
Distance = 40 kilometers
Time taken = 10 hour
Find:
Distance cover in 7 hour
Computation:
Distance cover in 7 hour = (40/10)7
Distance cover in 7 hour = (4)7
Distance cover in 7 hour = 28 kilometer

Step-by-step explanation:
This is an incomplete question. Kindly complete it for assistance
Step-by-step explanation:
Aaron (A)=30 years old currently. (Aaron's son (S)=10 years old currently)
PREMISES
3S+10=2(S+10)
ASSUMPTIONS
Let A=Aaron's “current” age (3S in terms of his son's age)
Let S=Aaron's son's “current” age (S)
CALCULATIONS
3S+10=2(S+10)
3S+10=2S+20
(3S-2S)+10=(2S-2S)+20
S+10=0+20
S+(10–10)=20–10
S+0=10
S=
10 years old
and,
if S=10 years old, then
A=3S (Aaron's “current” age in terms of his son's age)
A=3(10)
A=
30 years old
PROOF
If A=30 years old, then the equations
3S+10=2(S+10)
3(10)+10=2(10)+20
30+10=20+20 and
40=40 establish the roots (zeros) A, S={30 years old, 10 years old} of the mathematical statement 3S+10=2(S+10)
A dump truck bar 1/3 of a ton of rocks on the 1st beat trip when half of a ton on the 2nd trip and forfeits of a tone on the 3rd trip what was the total way of the rock.
Answer: 1/30
Step-by-step explanation:
Here's the correct question:
A dump truck brought 1⁄3 of a ton of rock on the first trip, 1⁄2 of a ton on the second trip, but on the third trip, had to take back 4⁄5 of a ton. What was the total weight of the rock left at the construction site?
To calculate the the total weight of the rock left at the construction site goes thus:
= 1/3 + 1/2 - 4/5
The lowest common multiple of 3,2 and 5 is 30. Therefore, we'll make the fractions have a common denominator.
= 1/3 + 1/2 - 4/5
= 10/30 + 15/30 - 24/30.
= 1/30

Prove that:
1+cot²a / 1 + cosec a = cosec a
Step-by-step explanation:
LHS= 1 + cot^2A/1+cosecA
=(1+cosecA + cot^2A)/1+cosecA
{By using basic trigonometric theorem cot^2A = cosec^2A - 1}
=(1+cosecA + cosec^2A - 1)/(1+cosecA)
=(cosecA + cosec^2A)/(1+cosecA)
=[cosecA (1+cosecA)]/(1+cosecA)
{Cancelling 1+cosecA}
=cosecA

Graph g is a translation of the graph of y= sin x (dashed line).a) write down the equation of g b) write down the coordinates of the point p
Answer:
a) [tex]G(x)= \sin x + 2[/tex]
b) The coordinates of P are
[tex]\displaystyle \left( \frac{3\pi}{2},1\right)[/tex]
Step-by-step explanation:
Translation
The dashed line shows the graph of the function
[tex]y = \sin x[/tex]
This function has a maximum value of 1, a minimum value of -1, and a center value of 0.
a)
Graph G shows the same function but translated by 2 units up, thus the equation of G is:
[tex]\boxed{G(x)= \sin x + 2}[/tex]
b) The coordinates of P correspond to the value of
[tex]x = \frac{3\pi}{2}[/tex]
The value of G is
[tex]\displaystyle G(\frac{3\pi}{2})= \sin \frac{3\pi}{2} + 2[/tex]
Since
[tex]\sin \frac{3\pi}{2}=-1[/tex]
[tex]\displaystyle G(\frac{3\pi}{2})= -1+ 2=1[/tex]
The coordinates of P are
[tex]\displaystyle \left( \frac{3\pi}{2},1\right)[/tex]

how do you find the value in a ratio?
Answer:
In mathematics, a ratio indicates how many times one number contains another. For example, if there are eight oranges and six lemons in a bowl of fruit, then the ratio of oranges to lemons is eight to six. Similarly, the ratio of lemons to oranges is 6∶8 and the ratio of oranges to the total amount of fruit is 8∶14.

The terminal side of ø quadrant IV and sin ø = -12/13. What is the cos ø?
A. 5/13
B. 5/12
C. -5/12
D. -5/13
Answer:
Step-by-step explanation:
cos^2θ = 1 - sin^2θ = 1 - 144/169 = 25/169
cos θ is positive in Quadrant IV
cos θ = √(25/169) = 5/13
The value of the cos θ is 5/13 because cos is positive in IV option (A) is correct.
What is Trigonometric functions?Trigonometric functions defined as the functions which show the relationship between angle and sides of a right-angled triangle.
We have: The terminal side of θ is in quadrant IV quadrant
sinθ = -12/13
cos²θ = 1 - sin²θ
cos²θ = 1 - (-12/13)²
cos²θ = 1 - 144/169
cos²θ = 25/169
cos θ = √(25/169)
cos θ = 5/13
cos θ is positive in Quadrant IV
Thus, the value of the cos θ is 5/13 because cos is positive in IV option (A) is correct.

1. (2x^2+x-1)
Step-by-step explanation:
expanding (2x^2-1)^2. multiplying (x-2) (1-2x)
= 4x^2-4x+1. = x-2x^2-2+4x
= -2x^2+5x-2

The increase in pressure (P) is a linear function of the depth (d) to which a scuba diver descends. This is the function: P(d)=0.445d + 14.7.
1.) What does the initial value represent?
2.) What does the rate of change represent?
Answer:
Initial value = 14.7
Rate of change = 0.445
Step-by-step explanation:
Given the linear function :
P(d) = 0.445d + 14.7
The linear equation above takes the general. Form of a slope - intercept equation :
y = mx + c
Where ; m = slope or gradient = rate of change in y per unit change in x
c = intercept , which is the intial value of y when x = 0
Thus using the above information ;
Initial value = intercept value = 14.7
The rate of change is the slope value = 0.445
One number is 1 more than 7 times the other number. If their sum is 73 more than
twice the smaller number. Find the numbers.
[tex]\boxed{\boxed{\pink{\bf The \ two \ numbers \ are \ 12 \& \ 85 . }}}[/tex]
Step-by-step explanation:Given that , One number is 1 more than 7 times the other number. If their sum is 73 more than
twice the smaller number. And we need to find the numbers. So let us take the
First Number be x .Second number be 7x+1 .[tex]\underline{\red{\boldsymbol{ According \ to \ the \ Question :- }}}[/tex]
[tex]\bf\implies 2( Small \ no.) + 73 = Bigger \ no. + Smaller \ no.\\\\\bf\implies 2x + 73 = x + 7x + 1\\\\\bf\implies 2x + 73 = 8x + 1 \\\\\bf\implies 8x - 2x = 73-1 \\\\\bf\implies 6x = 72 \\\\\bf\implies x =\dfrac{72}{6} \\\\\bf\implies \boxed{\red{\bf x = 12 }}[/tex]
Hence the smaller number is 12 and the bigger number will be :-
[tex]\bf \implies Number_{bigger} = 7x + 1 \\\\\bf\implies Number_{bigger} =7(12)+1\\\\\bf\implies Number_{bigger} = 84 + 1 \\\\\bf\implies \boxed{\red{\bf Number_{bigger}=85 }}[/tex]
Hence the bigger number is 85 and the smaller number is 12.Step-by-step explanation:
let us say the number: x
7x+1=y
x+y=73+2x
y-73=2x-x
y-73=x or
x=y-73
then, 7x+1=y
x=y-73
then after,we'll substitute
7x+1=y
7(y-73)+1=y
7y-511+1=y
7y-510=y
7y-y=510
6y=510
y=510/6
y=85
x=y-73
x=85-73
x=12
Therefore y=85 & x=12
