Determine the unknown values, R and W, in the figure below.
Answer:
W = 28.63
R = 15.59
Step-by-step explanation:
From the right triangle given in the picture,
By applying sine rule in the triangle,
sin(57°) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]
= [tex]\frac{24}{W}[/tex]
W = [tex]\frac{24}{\text{sin}(57)}[/tex]
W = 28.63
Similarly, by tangent rule,
tan(57)° = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]
1.54 = [tex]\frac{24}{R}[/tex]
R = [tex]\frac{24}{1.54}[/tex]
R = 15.59

Answer:
D. y=-1/2x+5
Step-by-step explanation:
Slope-Intercept Form: y=mx+b
Line passes through y-axis at (0,5) so the "b" part of the equation is positive 5 on the y-axis. Slope is -1/2 so "m" is -1/2.

Answer:
180-118= 62
Answer is angle E= 62
Step-by-step explanation:
Vertical opposite angle of 118 is 118
So, we found out the interior angle. And sum of interior angles is 180. So you subtract 118 from 180 to get angle E.
Hope this helps!!!
Answer:
E is 62
Step-by-step explanation:
First find any angle relationships with the angle 118.
You can see that 118 can go next to E (corresponding angles).
That is a straight line, so in total it will 180 degrees.
180-118 would be E.
180-118 is 62.
hope this helps! :)

Eric´s mother drives to work in 20 min when driving at her usual speed. When traffic is bad, she drives 10 miles per hour slower, and the trip takes 10 minutes longer. What is Eric´s mother´s usual speed?
Answer:
30
Step-by-step explanation:
I could be wrong
The usual speed of Eric's mother is 4 miles per hour .
Eric´s mother drives to work in 20 min when driving at her usual speed.
Let the usual speed of Eric's mother be "u" miles per hour (mph)
When the traffic is bad she drives 10 miles per hour slower.
The speed of Eric's mother when the traffic is bad = u-10 mph
The time taken by Eric's mother when the traffic is bad = 30 min
[tex]\rm Displacement = \dfrac{Velocity }{Time }[/tex]
The considering the displacement in both the cases is same hence we can
say that
[tex]\rm \dfrac{u}{20/60} = \dfrac{-(u-10)}{30/60} \\\rm 3u = -2u +20 \\5u = 20 \\u = 4[/tex]
So the usual speed of Eric's mother is 4 miles per hour .

-9x + 3 > 39 OR - 5x + 6 < 16
9514 1404 393
Answer:
(-∞, -4) ∪ [-2, ∞)
Step-by-step explanation:
The solution to the first inequality is ...
-9x +3 > 39
-9x > 36 . . . . . subtract 3 from both sides
x < -4 . . . . . . . divide both sides by -9; reverse > to < because -9 is negative
__
The solution to the second inequality is ...
-5x +6 ≤ 16
-5x ≤ 10 . . . . . . . subtract 6 from both sides
x ≥ -2 . . . . . . divide both sides by -2; reverse ≤ to ≥ because -2 is negative
__
These solution sets are disjoint. The solution of the OR of these inequalities is the union of the solution sets. The graph is shown below. In interval notation, it is described by ...
(-∞, -4) ∪ [-2, ∞)
The -2 has a square bracket because it is included in the set. The curved bracket at -4 indicates it is not included.

The shape of this particular section of the rollercoaster is a half of a circle. Center the circle at the origin and assume the highest point on this leg of a roller coaster is 30 feet above the ground.
1. Write the equation that models the height of the roller coaster.
a. Start by writing the equation of the circle. (Remember that the general form of a circle with the center at the origin is x^2 + y^2 = r^2
b. Now solve this equation for y. (Remember the roller coaster is above ground, so you are only interested in the positive root.
2. Graph the model of the roller coaster using the graphing calculator. Either sketch by hand or take a picture and paste the image below.
Answer:
Step-by-step explanation:
Part A
x^2 + y^2 = 30^2
I don't know if this is right or not. That would mean that the roller coaster has no clearance and at the lowest point, it would scrape the ground (although not enough to dig a hole).
Part B
y^2 = 900 - x^2
y = sqrt(900 - x^2)
Part C
The graph is actually y = - sqrt(900 - x^2)
That's the only model I can come up with
The wording of the question does not allow for the condition that you want. (0,0) is not the center of the graph the way they want it. See the second graph).
Perhaps it means graph15b. I can't really tell.
If AABC~ADEF, what is the scale factor of AABC to ADEF?
Given:
[tex]\Delta ABC\sim \Delta D E F[/tex]
[tex]AB=18,BC=21,AC=24,EF=7[/tex]
To find:
The scale factor of [tex]\Delta ABC[/tex] to [tex]\Delta D EF[/tex].
Solution:
We have,
[tex]\Delta ABC\sim \Delta D EF[/tex]
So, side BC is the corresponding side of EF.
Now, scale factor of [tex]\Delta ABC[/tex] to [tex]\Delta D EF[/tex] is
[tex]\text{Scale factor}=\dfrac{\text{ Side of }\Delta D EF}{\text{Corresponding side of }\Delta ABC}[/tex]
[tex]\text{Scale factor}=\dfrac{EF}{BC}[/tex]
[tex]\text{Scale factor}=\dfrac{7}{21}[/tex]
[tex]\text{Scale factor}=\dfrac{1}{3}[/tex]
Therefore, the scale factor of [tex]\Delta ABC[/tex] to [tex]\Delta D EF[/tex] is [tex]\dfrac{1}{3}[/tex].

What is mean by Triangle?
A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.
Given that;
The triangle is shown in figure.
Now,
We know that;
⇒ tan θ = Perpendicular / Base
Here, Perpendicular distance = x
And, Base = 6
Substitute all the values, we get;
⇒ tan θ = Perpendicular / Base
⇒ tan 30° = x/6
⇒ 1/√3 = x/6
⇒ x = 6/√3
⇒ x = 2√3
Thus, The value of 'x' will be;
⇒ x = 2√3
