Answers
9514 1404 393
Answer:
y -1 = 4(x +1)
Step-by-step explanation:
The point-slope form of the equation of a line with slope m through point (h, k) is ...
y -k = m(x -h)
For m=4 and (h, k) =(-1, 1), the equation is ...
y -1 = 4(x +1)

Answer: x = 32°
Step-by-step explanation:
(3x - 4) + (3x - 8) = 180
3x - 4 + 3x - 8 = 180
6x - 12 = 180
6x - 12 + 12 = 180 + 12
6x = 192
6x ÷ 6 = 192 ÷6
x = 32
A mailbox that is 4 1/2 feet tall casts a shadow that is 6 feet long. At the same time, a nearby ferris wheel casts a shadow 84 feet long. Find the height of the ferris wheel.
60 feet
Answers
Answer: 63 ft
Step-by-step explanation:
We can think of the shadow and height of objects as the catheti of a triangle rectangle.
We also know the relationship:
Tan(θ) = (opposite cathetus)/(adjacent cathetus)
if we define:
Tan(θ) = k (a real number, such that will be the same number for every object, because it depends on the angle θ that will depend on the position of the sun)
opposite cathetis = heigt.
adjacent cathetus = length of the shadow.
Then we have:
k = height/length of the shadow.
For the mailbox, we know that the height is (4 + 1/2) ft and the shadow is 6ft long, then we have the equation:
k = (4 + 1/2)ft/6ft = 0.75
Then for the ferris wheel we know:
shadow length = 84ft
we can write the same equation as above:
k = 0.75 = height/84ft
0.75*84ft = height = 63ft
The ferris wheel is 63 ft high.

63 feet

Write down three integers,all less than 25,whose range is 8 and mean is 11.
Answers
let
x------> the first integer
y------> the second integer
z-----> the third integer
x < y < z < 25
we know that
Median=13
Median=(x+y+z)/3
13=(x+y+z)/3
x+y+z=39------> equation 1
range=10
The range is the difference between the largest number within the set and the smallest number in the set
so
range=z-x
z-x=10------> z=x+10-----> equation 2
to find the solution we will assume different values of x (See the attached table)
terms
x < y < z < 25
z=x+10
y=39-z-x
The solution can be
7,15,17
8,13,18
9,11,19

If you start a bank account with $100 and you deposit $25 each month, what equation
correctly represents this situation?

so you start with $100
every month you get $25
so you could call $25 n
so every month you get n added to the bank account
