In ΔUVW, u = 480 cm, v = 180 cm and ∠W=120°. Find the length of w, to the nearest centimeter.
Answer:
591
Step-by-step explanation:
The length of w from the given triangle UVW is 591 cm.
What is cosine rule?The law of cosine states that the square of any one side of a triangle is equal to the difference between the sum of squares of the other two sides and double the product of other sides and cosine angle included between them. The law of cosine states that: a² = b² + c² - 2bc·cosA.
Given that, in ΔUVW, u = 480 cm, v = 180 cm and ∠W=120°.
w² = u² + v² - 2uv·cosW
w² = 480² + 180² − 2×480×180·cos120°
w² = 230400 + 32400 - 172800·(-0.5)
w² = 349200
w = √349200
w = 590.93
w = 591 cm
Therefore, the length of w is 591 cm.

Answer:
128°
Step-by-step explanation:
x + 154° + 78° = 360° {being complete turn}
x + 232° = 360°

x = 128°
someone report this so it will get taken down
- x + 2y = 0
x + 2y = 1
Answer:
-no answer-
Step-by-step explanation:
Use elimination (subtract one equation from the other to get rid of one of the variables)
x+2y=1
- -x+2y=0
--------------------
---=1
(nothing equals one)
so this is not a valid system of equations.

Plot the vertex and the axis of symmetry of this function on the provided graph.
f(x) = (x + 2)^2 − 6
Answer:
(-2,-6)
-2
Step-by-step explanation:
To get the vertex take the number that's in the parathenses with the x and flip it's sign (in this case to a negative) which means we have
-2
this is the x coordinate of the vertex.
Next take the number that's being subtracted (or added) on the outside and leave that as is (-6)
This is the y coordinate
which means we have (-2,-6)
the axis of symmetry is just the x coordinate of the graph
which is -2

Find the value of each variable in the parallelogram.
Answer:
n = 12 , m = 5
Step-by-step explanation:
since it is said it is a parallelogram so opposite sides are equal
n = 12 (being opposite sides of parallelogram)
m + 1 = 6 (being opposite sides of parallelogram)
m = 6 - 1
m = 5

Solve the logarithmic equation. Round to the nearest ten-thousandth if necessary.
Solve log(4x
+
10) = 3.
Answer: x = 2.5214
Step-by-step explanation:
log(4x+10) = 3
e^(log(4x+10)) = e^3
E^ log cancels out and equals one so
4x + 10 = e^3
4x = e^3 -10
x = (e^3 - 10)/4
x = 2.5214

Function Notation
Given f(x)=8x−9
a. Find f(3y−1)=8(3y−1)−9=
b. If f(x)=−23, find the value of x.
Step-by-step explanation:
Given
f(x) = 8x - 9
Then
For a.
f(3y - 1 ) = 8(3y - 1 ) - 9
= 24y - 8 - 9
= 24y - 17
Now for b.
f(x) = - 23
or, 8x - 9 = - 23
8x = - 23 + 9
8x = - 14
x = - 14 / 8
x = - 7 / 4

Luca pays $165 per month for his car loan and an average of $2.30 per gallon of gas. He wants to keep his car expenses under $300 per month. Write and solve an inequality to find the greatest number of gallon "g", Luca can drive in a month while staying within his budget?
Answer:
58.69 gallons is the maximum she can get.
Step-by-step explanation:
165 + 2.3g ≤ 300
subtract 165 from both sides
2.3g ≤ 135
divide by 2.3 on both sides
g ≤ 58.6956521739

To rent a bounce house: At Mike's Bounce Shop costs $30 plus $2 per hour. At Jose's Bounce Rentals, it costs $12 plus $8 per hour. After how many hours will the rental cost at both shops be equal? What do your variables represent?Solve the problem using the Equal Values Method. Show your work for finding x AND y.
Answer: After 3 hours both will have the same cost.
Step-by-step explanation:
Let x = Number of hours and y be the total cost.
Total cost = Initial cost + (cost per hour)(Number of hours)
At Mike's Bounce Shop,
Total cost (y)= 30+2x
At Jose's Bounce Rentals,
Total cost(y) = 12+8x
When both shops have the same cost, then
[tex]12+8x=30+2x\\\\\Rightarrow\ 8x-2x=30-12\\\\\Rightarrow\ 6x=18\\\\\Rightarrow\ x=3[/tex]
Total cost = 12+8(3)=12+24=$36
Hence, After 3 hours both will have the same cost.

ariana is going to invest in an account paying an interest rate of 1.9% compounded monthly. how much would ariana need to invest,to the nearest ten dollars,for the value of the account to reach $110,000 in 14 years?
9514 1404 393
Answer:
$84,330
Step-by-step explanation:
The compound interest formula gives the value of an investment.
A = P(1 +r/n)^(nt)
where principal P is invested at annual rate r compounded n times per year for t years. Using your given values, we can solve for P.
110,000 = P(1 +0.019/12)^(12·14)
P = 110,000/(1 +0.019/12)^(12·14) ≈ 110,000/1.00158333...^168
P ≈ 110,000/1.30446
P ≈ 84326.04 ≈ 84,330 . . . . dollars
