Answer:
The time it will take is 8hours 45mins.
Step-by-step explanation:
Since y = –240x represents a submarine descent. We are looking for how long, that is the time, it will take for the submarine to make a descent of 2100. We know that y is the elevation, if it is descending it will be in the negative direction, making it -ve.
A descent of 2100 means y = –2100. Hence,
–2100 = –240x
x = –2100/–240 = 8.75hours = 8hours 45minutes. (0.75hours = 3/4hours = 3/4 x 60mins = 45mins).
Cody leaves his home and cycles 5y miles south, then cycles (2y + 10) miles east. Finally, he cycles (4y + 8) miles south and reaches his school. How far does Cody cycle (in terms of y)?
Answer:
11y + 20
Step-by-step explanation:
Given that:
Distance south = 5y miles
East = (2y + 10) miles
Final = (4y + 8) miles
Total cycle in terms of y
Take the sum of the distances :
5y + 2y + 10 + 4y + 8
11y + 20

Which of the following equations represent exponential growth functions? Choose all that apply.
a) f (x)=4^x
b) f (x)=(1/4)^-x
c) f (x)=(2/3)^x
d) f (x)= (2.3)^x
e) f (x)=(.8)^x
Option:-
a) f(x) = 4^x is applicable
b) f(x) ={ (1/4)^-x = 4^x }is applicable
c.) f(x) = (2/3)^x is not applicable
d.) f(x) = (2.3)^x is applicable
e.) f(x) = (.8)^x is not applicable
Options (a), (b) and (d) are exponential growth functions.
What is Exponential function?An exponential decay is in the form:
y = abˣ
where y, x are variables, a is the initial value of y and b is the multiplier which is less than 1.
By the Exponential decay form,
An exponential decay is in the form: y = abˣ
(a) f (x)=4ˣ is applicable as 4>1
(b) f (x)=(1/4)⁻ˣ is applicable as (1/4)-1=4>1
(c) f (x)=(2/3)ˣ is not applicable because 2/3<1
d) f (x)= (2.3)ˣ is applicable as 2.3>1
e) f (x)=(.8)ˣ is not applicable, 0.8<1.
So options (a), (b) and (d) are applicable for exponential growth functions.

A construction crew is building a two story house, but they have not built the staircase between the floor yet. The height of the staircase is 12 feet, the base of the stairs will be 6 feet from the wall. How long does the temporary ramp need to be to the nearest tenth of a foot?
Answer:
13.4feet
Step-by-step explanation:
The set up forms a right triangle.
Given
Height of the staircase h = 12 feet
Base of the stairs b = 6feet
Required
Length of the ramp l
Using the pythagoras theorem
l² = h² + b²
l² = 12²+6²
l² = 144 + 36
l² = 180
l = √180
l = 13.42 feet
Hence the length of the ramp to the nearest tenth is 13.4feet

What is the value of n?
Answer:
B. 85 degrees
Step-by-step explanation:
To find the top angle inside the tringle, do 180-133 = 47. To find the angle on the left, do 180 - 142 = 38. Do 180 - 47 + 38 = 95 to find the final angle. Then do 180-95 = 85 to find the angle wanted. This is all about using lines, because the angles on both sides of the line must add to 180 if one of the lines they lie on is the same. Hope this makes sense.

Answer:
x+6 y+3
Step-by-step explanation:
The translation shows a horizontal shift to the left by 6 units and vertical shift up by 3 units
Reflection of coordinate pointsReflection of any coordinates are mirror images of each other.
The reflection rule of the coordinate over the x-axis is given as:
(x, y) -> (x , -y)
Using the coordinate (-1, 2) on the image on the left and (5, 1) for the coordinate on the right.
Reflecting (-1, 2) over the x-axis is (-1,-2). In order to determine the translation used from (-1, -2) to (5, 1)
(-1+x, -2+y) = (5, 1)
-1 + x = 5
x = 6
-2 + y = 1
y =3
