Answer:
There are two options: b) [tex]\frac{\sqrt{15}}{4}[/tex], c) [tex]\sqrt{15}[/tex].
Step-by-step explanation:
By Trigonometry, we know that function tangent is equal to the following identity in terms of functions sine and cosine:
[tex]\tan \theta = \frac{\sin \theta}{\cos \theta}[/tex] (1)
If we know that [tex]\tan \theta > 0[/tex] and [tex]\sin \theta = \frac{1}{4}[/tex], then [tex]\cos \theta > 0[/tex]. Hence, we have two possibilities: b) [tex]\frac{\sqrt{15}}{4}[/tex], c) [tex]\sqrt{15}[/tex].

Louis wants to buy skis that have a regular price of $328. They have been marked down 25% off the regular price. Louis calculates the new total price including tax.
How much money will Louis save on the total cost because of the markdown?
Answer:
Part ACalculate sale price and add sales tax:
20% off $339 add tax ⇒ $339*0.8*1.085 = $294.25 ≤ $30015% off $310 add tax ⇒ $310*0.85*1.085 = $285.90 ≤ $30025% off $365 add tax ⇒ $365*0.75*1.085 = $297.02 ≤ $30020% off $300 add tax ⇒ $300*0.8*1.085 = $260.40 ≤ $300Each price is acceptable as less than $300
Part BMarkdown with tax added:
25% off $328 add tax ⇒ $328*0.75*1.085 = $266.91Without discount, the price with the tax added:
$328*1.085 = $355.88The difference is the amount Luis has saved:
$355.88 - $266.91 = $88.97Can someone pleaseeee help and if you’re correct i’ll give brainliest

Jacob deposits $60 into an investment account with an interest rate of 4%, compounded annually. The equation,
y = 60(1 + 0.04)x, can be used to determine the number of years, x, it takes for Jacob's balance to reach a certain amount of money, y. Jacob graphs the relationship between time and money.
1. What is the y-intercept of Jacob's graph?
2. If Jacob doesn't deposit any additional money into the account, how much money will he have in eight years? Round your answer to the nearest cent.
Answer:
1. 60 is his y-intercept
2. $82.11 in his account after 8 years
Answer:
The y-intercept of Jacob's graph is $60, which represents the initial amount of money he deposited into the account.
If Jacob doesn't deposit any additional money into the account, the amount of money he will have in eight years can be found by plugging in x=8 into the equation y = 60(1 + 0.04)^x and evaluating:
y = 60(1 + 0.04)^8
y ≈ $82.08
So the answer to the second question is that Jacob will have approximately $82.08 in the account after eight years, assuming he doesn't deposit any additional money into the account.
Hope this helps,

Write the equation of the line in fully simplified slope-intercept form.
Answer:
y = -6x - 8
Step-by-step explanation:
Two points on this line are (-3, 10) and (0, -8). Moving from the first to the second, we see that x increases by 3 and y decreases by 18. Thus, the rise and run are -18 and 3 respectively, so that the slope of this line is m = -6.
Adapt the slope-intercept form y = mx + b to this particular situation. Recognize that the given (0, -8) is the y-intercept and that the slope, m, is -6.
The equation of this line is thus
y = -6x - 8

Step-by-step explanation:
Find the measure of the indicated angle to the nearest degree.
Given:
A right triangle with legs 5 units and 6 units.
To find:
The measure of angle opposite of side whose length is 5 units.
Solution:
In a right angle triangle,
[tex]\tan \theta=\dfrac{Opposite}{Adjacent}[/tex]
Let [tex]\theta [/tex] be the missing angle. Then, for the given triangle,
[tex]\tan \theta=\dfrac{5}{6}[/tex]
[tex]\theta=\tan^{-1}\dfrac{5}{6}[/tex]
[tex]\theta=39.805571^\circ[/tex]
Round the value to the nearest degree.
[tex]\theta\approx 40^\circ[/tex]
Therefore, the measure of the required angle is 40 degrees.

y=3x−11;−3x+y=−13
Step: Solvey=3x−11 for y:
y=3x−11
Step: Substitute 3x−11 for y in−3x+y=−13:
−3x+y=−13
−3x+3x−11=−13
−11=−13(Simplify both sides of the equation)
−11+11=−13+11(Add 11 to both sides)

6c^2 - 5d + 8 when c =5 and d=4
Answer:
138
Step-by-step explanation:
First, we can simply replace the variables with their numerical values.
Whenever you see a number with a letter (variable) in front of it, this means to multiply.
c=5 and d=4
6 × 5^2 - 5 × 4 + 8
Since there are multiple operations in this expression, we must use PEMDAS.
ParenthesisExponentiation (exponents)Multiplication/Division (Solve whichever comes first)Addition/Subtraction (Solve whichever comes first)--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Now, we can apply the operations.
There are no parenthesis.
In this expression, exponents are present.
6 × 5^2 - 5 × 4 + 8
6 × 25 - 5 × 4 + 8
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
There is multiplication.
6 × 25 - 5 × 4 + 8
150 - 5 × 4 + 8
150 - 20 + 8
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
There is subtraction.
150 - 20 + 8
130 + 8
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
There is addition.
130 + 8
158
Therefore, 6 × 5^2 - 5 × 4 + 8 = 138.
Let u =LeftAngleBracket 3, 4 RightAngleBracket. What is 3u? LeftAngleBracket 6, 7 RightAngleBracket LeftAngleBracket 6, 12 RightAngleBracket LeftAngleBracket 9, 7 RightAngleBracket
Answer:
(9, 12)
Step-by-step explanation:
Given that :
u = (3, 4)
3u = 3(3, 4)
3u = 3(3, 4) = (9, 12)
Hence, 3u = (9, 12)
Answer:
<9, 12>
Step-by-step explanation:
Multiply X and Y values by the number of U there are.
u= <3,4>
2u=<6,8>
3u= <9,12> Multilpy By 3 to get 3u
Your answer is <9,12>.

Which of the following is not a factor of the polynomial p(x) = x³ - 23x² + 142x - 120?
Options :
A(x - 1)
B(x - 10)
C(x - 5)
D(x - 12)
no spam answers and explain how you got the solution.
Answer:
The correct answer is C- (X-5)Solution
Given -
polynomial p(x) = x³ - 23x² + 142x - 120
Now see the coefficients
coefficient of x³ is 1 x² is -23 x is 142 and then -120
when you'll add this coefficients
i.e.
1-23+142-120=0
When sum of the coefficient turn out 0 then x = 1
using x=1, x-1 = 0
devide the given polynomial p(x) = x³ - 23x² + 142x - 120 by x-1 you'll get rest two factors hence
Answer is option C

EASY- Han has to build the figure below, which will serve as a counterweight, for his robotics project. Find the VOLUME of the finished object assuming it is empty inside.
Given:
A combined figure of a triangular prism and a cuboid.
To find:
The volume of the finished object assuming it is empty inside.
Solution:
From the given figure it is clear that the dimensions of the cuboid are 6 cm, 8 cm and 5 cm.
So, the volume of the cuboid is:
[tex]V_1=length\times width\times height[/tex]
[tex]V_1=6\times 8\times 5[/tex]
[tex]V_1=240[/tex]
The volume of the cuboid is 240 cubic cm.
The area of a triangle is:
[tex]Area=\dfrac{1}{2}\times base\times height[/tex]
Thus, the base area of the triangular prism whose base is 8 cm and height 4 cm, is:
[tex]B=\dfrac{1}{2}\times 8\times 4[/tex]
[tex]B=16[/tex]
The volume of a triangular prism is:
[tex]V_2=Bh[/tex]
Where, B is the base area and h is the height of the prism.
The base area of the triangular prism is 16 square cm and the height is 5 cm. So, the volume of a triangular prism is:
[tex]V_2=16(5)[/tex]
[tex]V_2=80[/tex]
Now, the volume of the given figure is:
[tex]V=V_1+V_2[/tex]
[tex]V=240+80[/tex]
[tex]V=320[/tex]
Hence, the volume of the finished object is 320 cubic cm.
