Please help!! 13 points, will mark brainliest!! How to calculate [tex]cos (x)=\frac{6}{15}[/tex]?
I'm doing a trig question; trying to find angle XYZ, and I think the formula for the answer is C = [tex]\frac{A}{H}[/tex], which as stated in the title, I think in this situation is [tex]Cos(x)=\frac{6}{15}[/tex].
I don't know what I'm doing wrong, or if I've done the whole question wrong, but no scientific calculators will give me an answer because it says Cos is already defined. I know for sure the answer isn't 0.4, which was a guess I made. The entire question is attached below.
Answer:
66.4°
Step-by-step explanation:
Let ∠XYZ be x°.
Given the adjacent side, XY, and the hypotenuse side,YZ, we use cosine.
[tex] cosθ= \frac{adj}{hyp} \\ cosx° = \frac{6}{15} [/tex]
To find the value of x°, take the inverse of cosine.
[tex] x°\\ = cos^{ - 1} (\frac{6}{15} ) \\ = 66.4° \: (1 \: d.p.)[/tex]
Thus, ∠XYZ= 66.4°

Solve the equation
(1/2)-sinx=1
Answer: #2. sin x (sin x + 1) = 0
sin x = 0 or sin x + 1 = 0
sin x = 0 or sin x = -1
Step-by-step explanation:
the value of x will be x = 210° and 330° for the given expression (1/2)-sinx=1.
What is an expression?Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement. It's possible to multiply, divide, add, or subtract with this mathematical operation.
Given a equation (1/2)- sin x = 1
Simplifying the given expression
=> (1/2)- sin x = 1
subtract 1/2 on both sides
=> -sin x = 1/2
=> sin x = -1/2
=> x = 210° and 330°
For all x = 0 to 360°

Find the value of c so that (x+1) is a factor of the polymonial p(x)=5x^4+7x^3-2x^2-3x+c
Answer:
BRAINLIEST PLZZZZ
Step-by-step explanation:
Also given that (x+1) is factor of given polynomial p(x).
Need to determine value of constant c.
We will be solving above problem using factor theorem.
Factor theorem says that if ( x – a) is a factor of any polynomial f(x) , then f(a) = 0.
As in our case f(x) = p(x) and factor of p(x) is (x + 1) , which can be rewritten as (x – ( -1)) , so "a" in our case is -1 .
According to factor theorem p(-1) = 0
On substituting x = -1 , in given expression of p(x) we get
Hence value of c in the given polynomial is 1
Answer:
c = - 3
Step-by-step explanation:
[tex] \because [/tex] (x+1) is a factor of the polymonial [tex] p(x)=5x^4+7x^3-2x^2-3x+c[/tex]
Let (x + 1) =0[tex] \implies [/tex] x = - 1
[tex] \therefore [/tex] at x = - 1, p(x) =0.
[tex]p(x)=5x^4+7x^3-2x^2-3x+c \\ \\ 0 = 5( { - 1})^{4} + 7( { - 1})^{3} - 2( { - 1})^{2} - 3( - 1) + c \\ \\ 0 = 5 \times 1 + 7( - 1) - 2 \times 1 + 3 + c \\ \\ 0 = 5 - 7 - 2 + 3 + c \\ \\ 0 = 7 - 7 + 3 + c \\ \\ 0 = 3 + c \\ \\ c = - 3[/tex]
After 4 minutes of reading, Aaron was on page 14 of his book. After 8 minutes he was on page 20. Which equation models the page number, y, in terms of minutes x?
Group of answer choices
y = 8x + 1.5
y = 1.5x + 8
y = −1.5x + 8
y = –8x + 1.5
Answer:
The answer would be (B) y = 1.5x + 8
Step-by-step explanation:
The equation that models the number of pages (y) and number of minutes (x) is y = 1.5x + 8.
What is Equation Modelling?Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.
Given is Aaron who is reading a book. After 4 minutes of reading, Aaron was on page 14 of his book and after 8 minutes he was on page 20.
Now -
(x) represents the number of minutes and (y) is the number of pages.
At x = 4, y = 14
At x = 8, y = 20
The slope of the line will be -
m = (20 - 14)/(8 - 4)
m = 6/4
m = 3/2
The general equation can be written as -
y = 3x/2 + c
20 = 3/2 x 8 + c
20 = 12 + c
c = 8
Now, we can write the equation as -
y = 1.5x + 8
Therefore, the equation that models the number of pages (y) and number of minutes (x) is y = 1.5x + 8.
