An airplane is flying in the direction of 30 degrees South of West at 600 mph. A wind is blowing in the direction of 60 degrees North of East at 40 mph.
are the component forms for the air and wind vectors.
The ground speed, G, of the plane is given by
.
Answer:
not sure for the 1st one but pretty sure 2nd one is B
Step-by-step explanation:
The ground speed (G) is given as
[tex]G = \sqrt{(600\dfrac{\sqrt3}{2} + 20)^2 + (300 + 40 \dfrac{\sqrt3}{2})^2}[/tex].
The correct potion is B.
What is a vector?The quantity which has magnitude, direction and follows the law of vector addition is called a vector.
An airplane is flying in the direction of 30 degrees South of West at 600 mph. A wind is blowing in the direction of 60 degrees North of East at 40 mph.
It means the airplane is flying in the opposite direction of the wind.
The component of an airplane will be
[tex]\rm x = - 600\ sin 30\\\\x = - \dfrac{600}{2}= -300\\\\y = -600 \ cos30\\ \\y= -\dfrac{600 \sqrt{3}}{2}[/tex]
The component of wind will be
[tex]\rm x = 40 cos 60\\\\x = \dfrac{40}{2} = 20 \\\\y = 40sin 45\\ \\y= \dfrac{40\sqrt3}{2}[/tex]
Then the ground speed will be
[tex]G = \sqrt{(600\dfrac{\sqrt3}{2} + 20)^2 + (300 + 40 \dfrac{\sqrt3}{2})^2}[/tex]
Then the correct potion is B.

If Jo drives 357 miles and uses 17 gallons of gas how many miles per gallon did he get? How far could Jo go on 50 gallons of gas?
He got 21 miles per gallon, which mean he would be able to go 1,050 miles with 50 gallons of gas.
Answer:
(a) 21 miles per gallon. (b) 1050 miles.
Step-by-step explanation:
357 / 17 = 21 miles per gallon.
21 * 50 = 1050 miles.

Answer:
12.8
Step-by-step explanation:
First cube the 3 to get 27.
Then, multiply 2 by 12/5 to get 24/5.
Remove the parentheses and then add 27 with 6 to get 33.
Then divide -24 by 5 to get -4.8.
Add -4.8 with 33 to get 28.2.
Then subtract 15.4 from 28.2 to get 12.8

Answer:
AB = 3 and AC = 4
Step-by-step explanation:
Given that the triangles are similar then the ratios of corresponding sides are equal, that is
[tex]\frac{AB}{WX}[/tex] = [tex]\frac{BC}{WY}[/tex] , substitute values
[tex]\frac{AB}{30}[/tex] = [tex]\frac{3}{30}[/tex] ( cross- multiply )
30AB = 90 ( divide both sides by 30 )
AB = 3
and
[tex]\frac{AC}{XY}[/tex] = [tex]\frac{BC}{WY}[/tex] , substitute values
[tex]\frac{AC}{40}[/tex] = [tex]\frac{3}{30}[/tex] ( cross- multiply )
30AC = 120 ( divide both sides by 30 )
AC = 4
Answer:
AB = 3AC = 4Step-by-step explanation:
Let AB = xLet AC = yGiven
ΔWXY ~ ΔBAC
Therefore, the triangles are similar, so corresponding sides would be in the same ratio, so
WY/ BC = XW/AB
substitute WY = 30, BC = 3, XW = 30, AB = x
30 / 3 = 30 / x
x = [30 × 3] / [30]
x = 90 / 30
x = 3
Thus,
AB = 3
now
WY/ BC = XY/AC
substitute WY = 30, BC = 3, XY = 40, AC = y
30 / 3 = 40 / y
y = [40 × 3] / [30]
y = 120 / 30
y = 4
Thus,
AC = 4
Therefore,
AB = 3AC = 4pls help....thanks..

3.1(g-7)-1=5.2 what is G
Answer:
g = 8.7
Step-by-step explanation:
3.1 (g - 7) = 5.2
Multiply by 3.1
3.1g - 21. 7 = 5.2
Add 21.7 to both sides
3.1g = 5.2 + 21.7
3.1g = 26.9
Divide both sides by 3.1
g = 26.9 / 3.1
g = 8.677 = 8.7
The population of a town decreases exponentially at a rate of 1.7% per year.
The population now is 250 000. Calculate the population at the end of 5 years
Give your answer correct to the nearest hundred.
Answer: 229,500 people to the nearest hundred
Step-by-step explanation:
Population decreases exponentially at 1.7% per year in a town that is currently 250,000 in number.
Population in 5 years = 250,000 * ( 1 - 1.7%) ⁵
= 250,000 * 0.917841286185143
= 229,460
= 229,500 people to the nearest hundred

Find the value of 9u - 6 given that -2u+2=6
Answer:
The value of 9u - 6 is -24
Step-by-step explanation:
Let us solve the question
∵ -2u + 2 = 6
→ Subtract 2 from both sides to move 2 from the left side to the right side
∵ -2u + 2 - 2 = 6 - 2
∴ -2u = 4
→ Divide both sides by -2 to find the value of u
∵ [tex]\frac{-2u}{-2}[/tex] = [tex]\frac{4}{-2}[/tex]
∴ u = -2
∵ The given expression is 9u - 6
→ Substitute u by -2 to find the value of the given expression
∴ 9u - 6 = 9(-2) - 6
∴ 9u - 6 = -18 - 6
∴ 9u - 6 = -24
∴ The value of 9u - 6 is -24

Matt Ali deposited $25,000 in a savings account. The account earns 5.5 percent interest compounded daily. Use the formula “ Amount of $1.00 at 5.5 Percent compounded Daily”. A). What amount will he have in his account 28 later ? B.) How much will be compound interest ?
Answer:
A) Amount = $ 116,601.31
B) Compound Interest = $ 91,601.31
Step-by-step explanation:
Compound interest Formula
A = P(1 + r/n)^nt
Where
P = Initial amount invested = $25,000
r = interest rate = 5.5 %
n = Compounding frequency = daily
t = time in years = 28 years
A). What amount will he have in his account 28 years later ?
First, convert R percent to r a decimal
r = R/100
r = 5.5%/100
r = 0.055 per year,
Then, solve our equation for A
A = P(1 + r/n)^nt
A = 25,000.00(1 + 0.000150685/365)^(365)(28)
A = $ 116,601.31
B.) How much will be compound interest ?
I = Amount - Principal
A(Amount ) = $ 116,601.31
P (principal) = $ 25,000.00
I = $ 116,601.31 - $ 25,000.00
I (interest) = $ 91,601.31

Solve the system of equations below
Answer:
The answer is B. (-7,-2)
Step-by-step explanation:
Multiply the first equation by 7,and multiply the second equation by -6.
7(−3x+6y=9)
−6(5x+7y=−49)
Becomes:
−21x+42y=63
−30x−42y=294
Add these equations to eliminate y:
−51x=357
Then solve−51x=357for x:
−51x=357 Divide both sides by -51
x=-7
Write down an original equation:
−3x+6y=9
Substitute−7forxin−3x+6y=9:
(−3)(−7)+6y=9
6y+21=9(Simplify both sides of the equation)
6y+21+−21=9+−21(Add -21 to both sides)
6y=−12
