Answer:
[tex]\cos(\theta_1) = \frac{\sqrt{111}}{20}[/tex]
Step-by-step explanation:
Given
[tex]\sin(\theta_1) = \frac{17}{20}[/tex]
[tex]Quadrant = 1[/tex]
Required
[tex]\cos(\theta_1)[/tex]
We know that:
[tex]\sin^2(\theta_1) + \cos^2(\theta_1) = 1[/tex]
This implies that:
[tex](\frac{17}{20})^2 + \cos^2(\theta_1) = 1[/tex]
Collect like terms
[tex]\cos^2(\theta_1) = 1 -(\frac{17}{20})^2[/tex]
[tex]\cos^2(\theta_1) = 1 -\frac{289}{400}[/tex]
Take LCM and solve
[tex]\cos^2(\theta_1) = \frac{400 -289}{400}[/tex]
[tex]\cos^2(\theta_1) = \frac{111}{400}[/tex]
Take square roots
[tex]\cos(\theta_1) = \frac{\sqrt{111}}{\sqrt{400}}[/tex]
[tex]\cos(\theta_1) = \frac{\sqrt{111}}{20}[/tex]
If a=2i+4j, b=2i-5j.What is the vector equation of line AB?.
Answer:
9j
Step-by-step explanation:
vector AB means going to B from A.
= pos. final - pos. initial
= pos.B - pos.A
= (2i + 4j) - (2i - 5j)
= 2i + 4j - 2i + 5j
= 9j

The ratio of cars to vans at “Mason’s Used Cars” is 7:5. The ratio of cars to vans at “Hyland Auto” is 4:3. There are 60 vans in each used car lot.
Which lot has more cars? How many more?
“Hyland Auto” added 2 vans (add to 60). Does this make the ratio the same in both cases? Explain.
Show all of your work.
Answer:
Mason's has 4 cars more.
no, it is still not the same ratio.
Step-by-step explanation:
each lot has 60 vans.
the ratio of cars/vans at Mason's is 7:5.
this means for every group of 5 vans there are 7 cars.
how many groups of 5 vans are there ? 60/5 = 12
so, for each of the 12 groups of 5 vans there are 7 cars.
=> 12×7=84
another way to get there (and faster) :
you can also say that a ratio is actually a division.
7:5 is 7/5
so, 60 × 7/5 = 12 × 7 = 84
in any case, Mason's has therefore 60 vans and 84 cars.
Hyland also has 60 vans, but a ratio of cars to vans of 4:3.
let's do the fast route :
60 × 4/3 = 20 × 4 = 80
Hyland has therefore 60 vans and 80 cars.
so, Mason's has more cars (4 more than Hyland).
now Hyland adds 2 vans, having then 62 vans and still 80 cars.
so, the ratio cars to vans is now 80:62. or 80/62
=> 80/62 = 40/31 which cannot be further simplified, as 31 is a prime number.
40/31 is not equal to 7/5. so, it is still not the same ratio.

The graphs below have the same shape. What is the equation of the blue
graph?
g(x) = ?
ve

-5
g(x) =
O A. g(x) = (x+3)2 - 2
O B. g(x) = (x - \3)2 - 2
xx
O c. g(x) = (x + 3)2 + 2
O D. g(x) = (x – 3)2 + 2
The equation of the translated function is:
g(x) = (x + 3)^2 - 2
How to get the equation for the blue graph?
We can see that the blue graph is a translation of the red one, where the equation for the red graph is:
f(x) = x^2
Remember that the translations are:
Horizontal translation:
For a general function f(x), a horizontal translation of N units is written as:
g(x) = f(x + N).
If N is positive, the shift is to the left.If N is negative, the shift is to the right.Vertical translation:
For a general function f(x), a vertical translation of N units is written as:
g(x) = f(x) + N.
If N is positive, the shift is upwards.If N is negative, the shift is downwards.By analyzing the vertices, we can see that the vertex of the blue graph is at (-3, -2) so we have a translation of 3 units to the left and 2 units down, meaning that we have:
g(x) = f(x + 3) - 2 = (x + 3)^2 - 2
So the correct option is A.

En una oficina hay 96 computadores en total. La razón entre los computadores que deben ser reparados y aquellos que se encuentran operativos es 3 : 5. ¿Cuántos computadores de la oficina deben ser reparados en total?
Answer:
36 computadores deben ser reparados.
Step-by-step explanation:
Dado que en una oficina hay 96 computadores en total, y la razón entre los computadores que deben ser reparados y aquellos que se encuentran operativos es 3:5, para determinar cuántos computadores de la oficina deben ser reparados en total se debe realizar el siguiente cálculo:
(96 / (3+5)) x 3 = computadores que deben ser reparados
(96 / 8) x 3 = computadores que deben ser reparados
12 x 3 = computadores que deben ser reparados
36 = X
Por lo tanto, 36 computadores deben ser reparados.

On a coordinate plane, triangles R S T and L M N are shown. Triangle R S T has points (5, 5), (2, 1), and (1, 3). Triangle L M N has points (0, negative 1), (2, negative 4), and (negative 2, negative 3). How does the area of triangle RST compare to the area of triangle LMN? The area of △RST is 2 square units less than the area of △LMN. The area of △RST is equal to the area of △LMN. The area of △RST is 2 square units greater than the area of △LMN. The area of △RST is 4 square units greater than the area of △LMN.
Answer:
The answer should be "B" (The area of △RST is equal to the area of △LMN.)
The area of ΔRST is equal to the area of ΔLMN.
How to find the area of a triangle from its vertices ?We know that, if the vertices of a triangle are [tex](x_{1},y_{1}), (x_{2} ,y_{2} ), (x_{3} ,y_{3} )[/tex],
then the area of the triangle is [tex]\frac{1}{2}[/tex] | [tex]x_{1} (y_{2} -y_{3} )+x_{2} (y_{3} -y_{1} )+x_{3} (y_{1} -y_{2} )[/tex] |
What is the result of comparing area of two given triangles ?In ΔRST, Vertices are R=(5,5), S=(2,1), T=(1,3)
In ΔLMN, Vertices are L=(0,-1), M=(2,-4), N=(-2,-3)
Area of ΔRST = [tex]\frac{1}{2}[/tex] | [tex]x_{1} (y_{2} -y_{3} )+x_{2} (y_{3} -y_{1} )+x_{3} (y_{1} -y_{2} )[/tex] |
= [tex]\frac{1}{2}[/tex] | 5(1-3)+2(3-5)+1(5-1) |
= [tex]\frac{1}{2}[/tex] | 5×(-2)+2×(-2)+4 |
= [tex]\frac{1}{2}[/tex] | -10-4+4 |
= [tex]\frac{1}{2}[/tex] | -10 |
Removing the absolute sign, we get,
Area of ΔRST = [tex]\frac{1}{2}[/tex] ×10 = 5 square unit
Again, Area of ΔLMN = [tex]\frac{1}{2}[/tex] | [tex]x_{1} (y_{2} -y_{3} )+x_{2} (y_{3} -y_{1} )+x_{3} (y_{1} -y_{2} )[/tex] |
= [tex]\frac{1}{2}[/tex] | 0(-4+3)+2(-3+1)-2(-1+4) |
= [tex]\frac{1}{2}[/tex] | 0+2(-2)-2(3) |
= [tex]\frac{1}{2}[/tex] | -4-6 |
= [tex]\frac{1}{2}[/tex] | -10 |
Removing the absolute sign, we get,
Area of ΔLMN = [tex]\frac{1}{2}[/tex] ×10 = 5 square unit
Hence, we can say that, the area of ΔRST = the area of ΔLMN

Your house had a value of $480,000 and increased in value by 3.5%. How much is your house worth now?
Answer:
$496,800
Step-by-step explanation:
Present cost = $480,000
%increase = 3.5%
Present price of the house = 480,000 + 3.5% of 480,000
= 480,000 + 0.035 * 480,000
= 480,000 + 16,800
= $496,800
Present price of the house = $496,800
