Answer:
$3,221.02
Step-by-step explanation:
Month 1: $2000 x 1.10 = $2,200
Month 2 = $2,200 x 1.10 = $2,420
Month 3 = $2,420 x 1.10 = $2,662
Month 4 = $2,662 x 1.10 = $2,928.2
Month 5 = $2,928.2 x 1.10 = $3,221.02

Find the exact value using a half angle identity. Cos(-pi/8)
9514 1404 393
Answer:
cos(-π/8) = (√(2+√2))/2
Step-by-step explanation:
The half-angle formula is ...
[tex]\cos{\dfrac{\theta}{2}}=\pm\sqrt{\dfrac{1+\cos{\theta}}{2}}[/tex]
Since cosine is an even function, cos(-π/8) = cos(π/8).
For θ/2 = π/8, θ = π/4 and cos(θ) = (√2)/2. Filling in the formula, we have ...
[tex]\cos{(-\dfrac{\pi}{8})}=\cos{\dfrac{\pi}{8}}=\sqrt{\dfrac{1+\cos{\dfrac{\pi}{4}}}{2}}=\sqrt{\dfrac{1+\dfrac{\sqrt{2}}{2}}{2}}\\\\=\sqrt{\dfrac{2+\sqrt{2}}{4}}=\boxed{\dfrac{\sqrt{2+\sqrt{2}}}{2}}[/tex]

Write the equation of a line in point slope form that passes through (-1, 4), and is perpendicular to y = -4x +3
Answer:
y = 1/4x + 17/4
Step-by-step explanation:
Slope-Intercept Form: y = mx + b
Perpendicular lines have the negative reciprocal slope.
m = 1/4
y = 1/4x + b
4 = 1/4(-1) + b
4 = -1/4 + b
17/4 = b
y = 1/4x + 17/4

A chemical manufacturer wants to lease a fleet of 26 railroad tank cars with a combined carrying capacity of 560,000 gallons. Tank cars with three different carrying capacities are available: 7,000 gallons, 14,000 gallons, and 28,000 gallons. How many of each type of tank car should be leased?
Answer:
16 of the 28,000 gallon tanks
6 of the 14,000 gallon tanks
4 of the 7000 gallon tanks
Step-by-step explanation:
ez
The tank should be leased by each quantity by 4 tank cars of 7000 gallons , 6 tank cars of 14000 gallons and 16 tank cars of 28000 gallons .
What is elimination method?In the elimination method, we eliminate any one of the variables by using basic arithmetic operations and then simplify the equation to find the value of the other variable. Then we can put that value in any of the equations to find the value of the variable eliminated.
According to the question
Let Tank cars of 7000 gallons = x
Let Tank cars of 14000 gallons = y
Let Tank cars of 28000 gallons = z
A chemical manufacturer wants to lease a fleet of 26 railroad tank cars with a combined carrying capacity of 560,000 gallons.
i.e ,
x + y + z = 26 ---------------------------------------(1)
and
7000x + 14000y + 28000z = 560000
x + 2y + 4z = 80 --------------------------------(2)
Now , solving equation (1) and (2) by elimination method
x = 4
y = 6
z = 16
Hence, The tank should be leased by each quantity by 4 tank cars of 7000 gallons , 6 tank cars of 14000 gallons and 16 tank cars of 28000 gallons .

Dan’s number is three times more than Michael’s. The sum of their numbers is 48. What are their numbers?
Answer:
michael's number is 12, therefore Dan's is 36.
Step-by-step explanation:
48= michael's number+ 3 times Michael's number
48= m+3m
48= 4m
48÷4= 12 = michael's number
since Dan's is 3 times Michael's, his number is 36.
Answer: Michale's number is 12 and Dan's is 36
Step-by-step explanation:
Using ratios you can create 3:1 which is Dan's ratio to Michale.
You add 3 and 1, which gives you 4.
Divide 48 by 4, which gives you 12.
Michale's part of the ratio is 12 as he has three times less than Dan.
Which concludes that Dan has 36 and Michale has 12.

3g + 5 = 7g + 4 asap and please show work!!!!
The solution of the equation 3g + 5 = 7g + 4 will be 1/4.
What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.
The equation is given below.
3g + 5 = 7g + 4
Simplify the equation, then we have
3g + 5 = 7g + 4
- 7g + 3g = 4 - 5
- 4g = - 1
g = (-1) / (-4)
g = 1 / 4
The solution of the equation 3g + 5 = 7g + 4 will be 1/4.

Plot the line for the equation on the graphy,−5=3/2(x−2)
Answer:
The equation of the line is:
y - 5 = 3/2 (x - 2)
Transforming the line into the slope intercept form:
y = 3x/2 - 3 + 5
y = 3x/2 + 2
The slope is 3/2 and the y-intercept is 2.
Plotting this on the graph can be done using these steps:
Locate the point (0,2) on the graph.
From (0,2), count 3 units up and 2 units to the left and indicate that point.
Finally, connect the two points and extend the line.
