Given:
The diagram of two right triangles.
To find:
The value of d and a.
Solution:
In a right angle triangle,
[tex]\tan \theta=\dfrac{Perpendicular}{Base}[/tex]
[tex]\sin \theta=\dfrac{Perpendicular}{Hypotenuse}[/tex]
(a) In first triangle,
[tex]\tan 60^\circ=\dfrac{d}{4}[/tex]
[tex]\sqrt{3}=\dfrac{d}{4}[/tex]
[tex]4\sqrt{3}=d[/tex]
Therefore, [tex]d=4\sqrt{3}[/tex].
(b) In second triangle,
[tex]\sin 45^\circ=\dfrac{a}{2}[/tex]
[tex]\dfrac{1}{\sqrt{2}}=\dfrac{a}{2}[/tex]
[tex]\dfrac{2}{\sqrt{2}}=a[/tex]
[tex]\sqrt{2}=a[/tex]
Therefore, [tex]a=\sqrt{2}[/tex].
determine if the following system of equations has no solutions, infinitely many solutions or exactly one solution. x+y=5 2x-y=-3
Answer:
(2/3, 13/3) (Exactly one solution)
Step-by-step explanation:
Write these equations in a column:
x+y=5
2x-y=-3
Note that we can eliminate y immediately by adding these two equations together. We get:
3x = 2, so that x = 2/3.
Substituting 2/3 for x in the first equation, we get:
2/3 + y = 5. Clear out fractions by multiplying all three terms by 3:
2 + 3y = 15, or 3y = 13. Then y = 13/3, and the solution is
(2/3, 13/3) There is exactly one solution.

Answer:
d = 637 ft below the surface
Step-by-step explanation:
Given
P = 14 + [tex]\frac{6}{13}[/tex] d
To find d when P = 308, then
14 + [tex]\frac{6}{13}[/tex] d = 308 ( subtract 14 from both sides )
[tex]\frac{6}{13}[/tex] d = 294 ( multiply by 13 to clear the fraction )
6d = 3822 ( divide both sides by 6 )
d = 637 ft
Answer:
637 feetStep-by-step explanation:
[tex]P=14+\dfrac6{13}d\\\\\\P=308\,,\qquad\qquad d=??\\\\\\308=14+\dfrac6{13}d\\\\ 308-14=\dfrac6{13}d\\\\294=\dfrac6{13}d\\\\d=294:\frac6{13}\\\\ d=294\cdot\frac{13}6\\\\d=637\,ft[/tex]

A movie theater offer two different plans to see movies. Plan One has members join for $75 and then pay only $2 per movie. The second plan offers movies for $5.75 per movie. For what number of movies will the costs be the same for both Plan One members and Plan Two members?
Answer:
I d k
Step-by-step explanation:
5.75x10=57.50
57.5+11.5=69(nice)
69+5.75= 74.75
74.75+5.75=80.5
80.5+5.75= 86.25
86.25+5.75=92
basically this formula should help

A rocket is launched from a tower. The height of the rocket, y in feet, is related to the
time after launch, x in seconds, by the given equation. Using this equation, find the
maximum height reached by the rocket, to the nearest tenth of a foot.
y = -16x2 + 125x + 147
Answer:
The maximum height of the rocket is about 391.1 feet.
Step-by-step explanation:
The height of the rocket y in feet x seconds after launch is modeled by the equation:
[tex]y=-16x^2+125x+147[/tex]
We want to find the maximum height reached by the rocket.
Since this is a quadratic equation, the maximum height occurs at the vertex. The vertex of a quadratic is given by:
[tex]\displaystyle \left(-\frac{b}{2a}, f\left(-\frac{b}{2a}\right)\right)[/tex]
In this case, a = -16, b = 125, and c = 147.
Thus, the x-coordinate of our vertex is:
[tex]\displaystyle x=-\frac{125}{2(-16)}=\frac{125}{32}[/tex]
To find the maximum height, we will substitute this value back in. So:
[tex]\displaystyle y_{\text{max}}=-16\left(\frac{125}{35}\right)^2+125\left(\frac{125}{32}\right)+147\approx391.1\text{ feet}[/tex]
The maximum height of the rocket is about 391.1 feet.

What is the area, in square meters, of the isosceles trapezoid below? 15.8 m 5-4 m 6.6 m Answer: A = ____ m squared
Answer:
5.618773 m2
I hope that this is the answer.
Answer:
answer is 60.48 m squared
Step-by-step explanation:
use the formula
a=1/2(b1+b2)h
a=1/2(15.8+6.6)h
a=1/2(22.4*5.4)
a=1/2(120.96)
a=120.96/2
a=60.48m

-13
Answer:
12
Step-by-step explanation:
Use the formula y1-y2/x1-x2 to find the slope from two points.
12
Plug in values into the formula using the given points
-7- -19/2-1
=--7+19/1
=12/1
=12
Answer:
The answer is 12
Step-by-step explanation:
The equation to find slope is [tex]m=\frac{y2-y1}{x2-x1}[/tex]. M is the slope.Then you need to add in the numbers. Your equations should look like this: [tex]m=\frac{-7+14}{2-1}[/tex] 14 is now positive because it was originally negative.Then you just solve it to get your answer 12.Which of the following expressions is equivalent to 4(m – 16)?
Answer:
4m - 64
Step-by-step explanation:
Solve 4(m - 16)
4(m - 16) = 4 x m - 16 x 4
= 4m - 64

Describe the transformations necessary to get from the graph of the parent function f(x)=x? to the
graph of the given function.
G(x)= 2(x - 3)^2 + 9
(Compress,Stretch)the graph vertically by a factor of_______
then translate the graph_______units to the (right,left)and _______ units (down,up)
Answer:
translate the graph 5 units left and down 2 units
Step-by-step explanation:
To translate the function f(x) by an amount h units right and k units up, make the transformation ...
g(x) = f(x -h) +k
Comparing this to your equation,
g(x) = f(x +5) -2
we see that the translation is h = -5, k = -2.
The graph of f(x) is translated 5 units left and 2 units down to make the graph of g(x).

- A cereal manufacturer needs to change the
size of its cereal box to fit on narrower
shelves. The dimensions of the current box
are 12 inches high by 9 inches wide by 2
inches deep. The new box will have the
same height and volume, but the width will
be reduced by 1 inch. What will be the
depth, to the nearest hundredth of an inch, of
the new cereal box?
Answer:
2.25 inch
Step-by-step explanation:
The current volume of box :
Volume = height * width * depth
Volume = 12 * 9 * 2
Volume = 216 in³
New dimension :
Height and volume are the same
Width = 9 - 1 = 8
Depth = x
Volume = height * width * depth
216 = 12 * 8 * x
216 = 96x
x = 216 / 96
x = 2.25 inch
Myra owns a car service that charges a $5 flat rate and an additional $0.50 per mile.
Write an equation that represents this information.
Answer: 5 + 0.5m
Step-by-step explanation:
Let the number of miles be represented by m.
Therefore, since there's a $5 flat rate and an additional $0.50 per mile, this can be formed into a equation as:
= 5 + 0.5m
For example if the number of miles taken is 100miles, the amount charged will be:
= 5 + 0.5m
= 5 + 0.5(100)
= 5 + 50
= $55
How do you find percentages?
Step-by-step explanation:
if you have 3/4 you divide the part, 3, by the whole, 4
3 ÷ 4 = 0.75
then multiply 0.75 by 100, 75, then add a percentage sign: 75%
