Answer:
[tex]y=\frac{15\sqrt{3} }{4}[/tex]
Step-by-step explanation:
Well what you have here are two right triangles within another right triangles created by an altitude. This results in 3 similar triangles (see attached for reference)
As a result , using the properties of similar triangles, and taking ratios of their sides of the medium triangle and the largest triangle, we can form the following relationship:
[tex]\frac{b}{z}=\frac{y}{x} = \frac{z}{a+b}[/tex] (we know that a+b = 15), hence the equation becomes:
[tex]\frac{b}{z}=\frac{y}{x} = \frac{z}{15}[/tex] ----------eq 1
If we consider the largest triangle, we will see that
cos 30° = z / 15
but from our special angles (see second attachment) we know that cos 30° = (√3)/2
hence
(√3)/2 = z / 15
z = (15√3) / 2 --------eq 2
from the same largest triangle, we will also see that
sin 30° = x / 15
similarly from our special angles, we know that sin 30° = 1/2
hence,
1/2 = x/15
x = 15/2 --------eq 3
now that we have values for x and z, we can neglect the first term of equation 1 and form an equality with x, y and z
[tex]\frac{y}{x} = \frac{z}{15}[/tex]
[tex]y = x\frac{z}{15}[/tex] (substituting the values for x and z that we found above)
y = (15/2) · [ (15√3) / 2] / 15
y = (15√3) / 4
[tex]y=\frac{15\sqrt{3} }{4}[/tex]
The quotient of 5 and a number, k ? Write the algebraic expression
Answer:
[tex] \frac{5}{k} [/tex]
Step-by-step explanation:
Quotient refers to the result we get when we divide a number by another number. In more precise words, the dividend (numerator) over the divisor (numerator) equals the quotient.
In this case, 5 is the dividend, k is the divisor, which is representing an unknown number.
We cannot get an actual number, but we can use algebraic expression to express the quotient as follows:
Quotient of 5 and k = [tex] \frac{5}{k} [/tex]

Ms. Lady works-out with Ms. Beetle; her average
crawling time has increased to 4 feet per minute, while
Ms. Beetle, who is used to eating Hot Cheetos and
watching TV, averages 2.5 feet per minute. While at
Senn's Elm Tree-house, the three decide to experiment
with linear equations. The objective is to end up at the
Rose Bush at the same time. Senn still averages 5 feet per
minute. How much of a head start does he need to give
each of his friends in order for their function rules to
intersect at 92 feet (the rose bush). What is the equation
for each bug which makes their experiment successful?
Create a table and graph representing the situation.
Answer: Please find the attached file for the graph and find the answer in the explanation
Step-by-step explanation:
Let first calculate the normal time each of them will reach the 92 feet distance.
For senn
Time = 92/5 = 18.4 minutes
That means in 18.4 minutes the two other friends must reach the point at 92 feet.
Calculate the distance at the time for each of the friends.
For Ms Lady
Time = 92/4 = 23 minutes
Distance = speed × time
Distance = 4 × 18.4 = 73.9
92 - 73.6 = 18.4 feet
For Ms Beetle
Time = 92/2.5 = 36.8 minutes
Distance = 2.5 × 18.4
Distance = 46 feet
92 - 46 = 48 feet
Therefore, Senn must give a head start of 18.4 feet for Ms Lady
And 48 feet for Ms Beetle in order for their function rules to intersect at 92 feet (the rose bush).
Their equation will be
Ms Lady
Y = 4x + 18.4
Ms Beetle
Y = 2.5x + 48
Ms Senn
Y = 5x

Rx = -419
Ry = -253
R = 490
θ = ____ ° counterclockwise from the +x-axis
Answer:
[tex]\theta = 148.8[/tex]
Step-by-step explanation:
Given
[tex]R_x = -419[/tex]
[tex]R_y = -253[/tex]
[tex]R = 490[/tex]
Required
Determine the value of [tex]\theta[/tex]
Since, [tex]\theta[/tex] is counter clockwise from x axis;
The relationship between [tex]\theta[/tex], [tex]R_x[/tex] and R is
[tex]cos\theta = \frac{R_x}{R}[/tex]
Substitute values for Rx and R
[tex]cos\theta = \frac{-419}{490}[/tex]
[tex]cos\theta = -0.8551[/tex]
Take arccos of both sides
[tex]\theta = cos^{-1}(-0.8551)[/tex]
[tex]\theta = 148.770784108[/tex]
[tex]\theta = 148.8[/tex] (Approximated)

Answer:
Option (A)
Option (D)
Step-by-step explanation:
From the graph attached,
Values of function have been plotted on y-axis for every input value of 'x' on x-axis.
Graph clearly states that the function is positive (positive y-values or y > 0) in the two intervals,
-5 < x < 0 and 3.5 < x < 5
Therefore, option (A) and Option (D) will be the correct options.

Determine whether f(x) = 3x + 1 and g(x) = (x-1) / 3 are inverses functions. Group of answer choices There are not inverses since both composition equal x. There are inverses since both composition equal x. There are inverses since both composition equal x + 1. There are not inverses since (f (g(x)) = x + 1
Answer:
They are inverses since both composition equal x.
Step-by-step explanation:
Given the functions, f(x) = 3x + 1 and g(x) = (x-1) / 3, to check if they are inverses functions, we are to find the inverse of one of the function and check if it will give us the other function.
Let's look for the inverse of f(x).
Given f(x) = 3x+1
Let y = f(x) so that y = 3x+1
Replace y with x
x = 3y+1
Make y the subject of the formula of the resulting equation;
3y = x-1
y = (x-1)/3
The new function of x will be the inverse of f(x)
Hence f^-1(x) = (x-1)/3 = g(x)
Another way to check is to find their composition. Let's find f(g(x) and g(f(x)
F(g(x)) = f((x-1)/3)
Replace x with (x-1)/3 in f(x)
F(g(x)) = 3[(x-1)/3]+1
F(g(x)) = x-1+1
F(g(x)) = x
Similarly for g(f(x));
g(f(x)) = g(3x+1)
Replace x in g(x) with 3x+1
g(3x+1) = (3x+1-1)/3
g(3x+1) = 3x/3
g(3x+1) = x.
Since g(f(x)) = f(g(x)) = x, hence f(x) and g(x) are Inverses functions
During a science experiment, Daniel noted the starting
temperature of a -4°F. At the end of the experiment, the
change in temperature was -5°F. What was the final
temperature?
A.-1 B.1 C.9 D.-9
Answer: D. - 9
Step-by-step explanation:
Give the following :
Starting temperature = - 4°F
At the end of the experiment, the change in temperature was -5°F
What was the final temperature?
Taking the difference of the starting temperature and the final temperature should give the change in temperature over the course of the experiment.
Δtemperature = (final temperature - initial temperature)
Δtemperature = - 5°F
Initial /starting temperature = - 4°F
Hence,
-5 = final temperature - (-4)
-5 = final temperature + 4
Final temperature = - 5 - 4
Final temperature = - 9

Consider the following exam question and student solution. Determine whether the solution is correct. If it is not correct, write a note to the student explaining why it is wrong and give a correct solution. Exam question: You can buy a 56 pound bag of flour for $9 or you can buy a 1-pound bag for .39 cents. Compare the per pound cost for the large and small bags. Student solution: The large bag price is 56 divided by 9=6.22 per pound, which is much more than the 39 cent per pound price of the small bag.
Answer:
actually a 56 pound bag cost =9
so one pound bag cost =9/56=0.16 cents

Consider the diagram Lines AC and RS are A coplanar. B parallel. C perpendicular D skew.
Answer: The answer is skew!
Step-by-step explanation:h
When lines are not parallel, and they do not intersect, such lines are said to be skewed.
Line AC and RS are skew.
From the diagram, we have two planes.
Plane xPlane yLine AC is on plane x, while line RS is on plane y
Plane x and plane y are not parallel;
So lines AC and RS are not parallel.
Also, both lines are not parallel.
Using the condition of skewness stated above, we can conclude that line AC and RS are skew.
