Answer:
11. MN = 4 m
12. LK = 8 m
Step-by-step explanation:
11. Apply pythagorean theorem to find MN:
MN = √(5² - 3²) = √(25 - 9) = √16
MN = 4 m
12. Recall: The ratio of the corresponding side lengths of any two given similar triangles are equal.
MN corresponds to LK
MO corresponds to KO
Therefore:
LK/MN = KO/MO
LK/4 = 10/5
LK/4 = 2
Multiply both sides by 4
LK = 2*4
LK = 8 m

The equation y=9x represents the total cost y for x movie tickets.
A.In this situation,which quantity is dependent and which is
independent? Justify your answer.
B.Eight friends want to go see a movie.what would the total cost be,explain how u found the answer.
Answers
Answer:
A) y or total cost is the dependent variable and x which is the number of movie tickets is the independent variable. Y is called dependent because its value depends on the value of x.
B) So 8 is the number of tickets which is X. So x=8. The total cost y will be: 8x9= 72

The volume of a hemisphere with a radius of 5.7 m is 193.83534 m³.
What is Volume?Volume is a mathematical term used to describe how much three-dimensional space an item or closed surface occupies. Volume is measured in cubic units like m3, cm3, in3, etc.
Volume is sometimes referred to as capacity.
We have,
Radius = 5.7 m
So, the Volume of Hemisphere
= 2/3 πr³
= 2/3 x 3.14 x (5.7)³
= 2/3 x 3.14 x 185.193
= 193.83534 m³
Thus, the volume is 193.83534 m³.

Use the Law of Cosines to find angle round to the nearest tenth if necessary).
Answers
Answer:
Step-by-step explanation:
3a)
find side HP , let's set side HP = c in the law of cosines formula
then
c = sq rt [ 23^2 + 12^2 - 2*12*23*cos(117) ]
c = sq rt [ 529 + 144 - (-250.6027559) ]
c = sq rt [ 673 + 250.6027559 ]
c = sq rt [ 923.602755 ]
c = 30.39
then
HP = 30.4 ( rounded to nearest 10th )
3b)
let PR = c, then law of cosines is (we need angle Q also 180=24+97+Q is 59°
c = sq rt [ 9^2 + 22^2 - 2*9*22*cos(59) ]
c = sq rt [ 81 + 484 -396*0.5150380 ]
c = sq rt [ 565 - 203.955 ]
c = sq rt [ 391.04495]
c = 19.7748
PR = 19.8 ( rounded to nearest 10th )
3c)
they want us to find ∠B, in the formula for cosines ∠B is really ∠C, it's a bit confusing.. I'm sure they did that on purpose to mess people up. Kind of underhanded :/ Tell the teacher that you're "appalled" at the deviousness of the test :/ stage a protest against math that teaches treachery :P storm the principals/ dean's office with paper airplanes and pictures of anime :DDD okay back to math.
a=28
b=17
c=15
since we want angle B then the formula looks like
B= arcCos ( a^2 + c^2 - b^2 / 2*a*c) so we'll avoid messing up the which side is which ... by setting up the formula this way .. got it?
B = arcCos [28^2 + 15^2 - 17^2 / 2*28*15]
B = arcCos[784 + 225 - 289 /840 ]
B = arcCos[720/ 840]
B = arcCos[0.85714285]
B = 31.0027 °
that it came out so close to an integer I'm pretty sure it's right
∠B = 31 .0 ° ( rounded to the nearest 10th )
3d)
find ∠A
set it up carefully again, they are asking us to move the variable around again
a = 18
b= 28
c= 12
then the formula looks like
∠A = arcCos[ b^2 + c^23 - a^2 / 2*b*c ]
∠A = arcCos[28^2 + 12^2 - 18^2 /2*28*12 ]
∠A = arcCos[784 + 144 -324 / 672 ]
∠A = arcCos[604/672]
∠A = arcCos[0.8988095]
∠A =25.99797 °
∠A =26.0 ° ( rounded to nearest 10th)

Answers
9514 1404 393
Answer:

Step-by-step explanation:
If m is the slope, the units of m can be found by considering the units of x and y.
y is in dollars
x is in hours
Then from the point of view of units, we have ...
dollars = m × hours
m = dollars/hours
The slope in the equation is the rental charge in dollars per hour.

Answers
Answer:
The vertex of the graph of g is 2 units above the vertex of the graph of f.
Step-by-step explanation:
The vertex of the graph of g(x) is 2 units above the vertex of the graph of f(x). Then the correct option is A.
What is a function?The function is an expression, rule, or law that defines the relationship between one variable to another variable. Functions are ubiquitous in mathematics and are essential for formulating physical relationships.
The graph of f(x) = x² was transformed to create a graph g(x) =f(x)+2.
Then the g(x) will be
g(x) = x² + 2
We know that the graph of the g(x) shifted to 2 units upward because we added 2 in the function.
The graph is shown.
The vertex of the graph of g(x) is 2 units above the vertex of the graph of f(x).
Thus, the correct option is A.

Answer:
AC = 16 in.
Step-by-step explanation:
AD = CD = 10 in.
BD = 6 in.
AC = 2(AB) = ?
Apply pythagorean theorem to find AB
AB² = AD² - BD²
Substitute
AB² = 10² - 6²
AB² = 64
AB = √64
AB = 8
Therefore:
AC = 2(AB) = 2(8)
AC = 16 in.
