Triangle R S T is shown. Angle R S T is a right angle. The length of R S is 10, the length of R T is 26, and the length of S T is 24. Use the diagram and side lengths of triangle RST to determine the angles used for the trigonometric ratios. sin( ) = Twelve-thirteenths tan( ) = Five-twelfths
Answer:
sin(R) = 12/13tan(T) = 5/12Step-by-step explanation:
The mnemonic SOH CAH TOA is intended to remind you of the relationship between sides of a right triangle and trig functions of the acute angles. It tells you ...
Sin = Opposite/Hypotenuse
sin(R) = 24/26 = 12/13
and ...
Tan = Opposite/Adjacent
tan(T) = 10/24 = 5/12
Answer: SIN = R and TAN = T

Evaluate the expression.
2−[(2+10(−1)÷2)+1]
What is the value of the expression?
4
Step-by-step explanation:Review
To evaluate the expression, lets use BODMAS. Before we get to the solving part, lets revise BODMAS.
=> B in BODMAS is brackets. This means that whatever operations are inside a bracket, we must solve that first.
=> O in BODMAS is Orders. The O is used very rarely, there is a possibility that there is no powers, exponents.
=> D in BODMAS is Division. This means that whatever division is occurring in the expression must be done first (Unless if there is a bracket).
=> M in BODMAS is Multiplication. This means that whatever multiplication is occurring in the expression must be done next.
=> A in BODMAS is Addition. This means that whatever addition is occurring in the expression must be done then.
=> S in BODMAS is Subtraction. This means that whatever subtraction is occurring in the expression must be done last.
Solution:Now, lets get to the point. We need to find the expression '2−[(2+10(−1)÷2)+1]'. Using the help of BODMAS, we can solve it.
Step 1: Simplify the innermost bracket.
2 − [( 2 + 10(−1)÷2)+1]
=> 2-[(2-10÷2)+1]
Note: Since in the innermost bracket there is no operation, we can open the innermost bracket and get along with the second inner bracket.
Step 2: Simplify the second inner bracket.
=> 2 - [(2 - 10 ÷ 2) + 1]
=> 2 - [(2 - 5) + 1]
=> 2 - [(-3) + 1]
=> 2 - [-3 + 1]
Step 3: Simplify the third inner bracket.
=> 2 - [-3 + 1]
=> 2 + 2
Step 4: Solve.
=> 2 + 2
=> 4
Final Answer.
Therefore, 4 is our answer after working on this problem.
Answer:
4
Step-by-step explanation:the answer is 4 because you have to 20 2-2+10 and that is ten. then minus one is 9 then 9/2=3 and then 3+1 equals 4
What is 8 times larger than 3
8 x 3 = 24 for should be 24
Only because 8 times larger than three seems like a multiplication problem..
I hope this helps if it is correct!
Answer:
(8+1) x 3 = 27
Step-by-step explanation:
this is correct rather than 8 x 3 = 24 because both sides of 8x3=24 are equal rather than the sum being greater than the statement.

what's the slope (3,-1) and (-2,5)
Answer:
slope = - [tex]\frac{6}{5}[/tex]
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (3, - 1 ) and (x₂, y₂ ) = (- 2, 5 )
m = [tex]\frac{5-(-1)}{-2-3}[/tex] = [tex]\frac{5+1}{-5}[/tex] = [tex]\frac{6}{-5}[/tex] = - [tex]\frac{6}{5}[/tex]
Determine if the ordered pairs (1. - 2) and (-4,2) are solutions of the following linear inequality in two variables.
-X<-y
.
Is the ordered pair (1. - 2) a solution of the linear inequality?
Is the ordered pair (-4,2) a solution of the linear inequality?
Answer:
First is, second is not.
Step-by-step explanation:
Start plugging them!
[tex]-(1) < -(-2) \rightarrow -1 < 2 \\ \\- (-4) < -(2) \rightarrow 4 < -2[/tex]
First one is true, so the pair is a solution.
Second is false, (4 is obviously bigger!) so it's not a solution.
If you end up having to check multiple values, your best bet is to draw the solutions on a convenient plane and see where the points lay

Tyrese says that 4(3x - 2) = 4x - 8.
Explain why his answer is not correct.
Leah is writing an equivalent equation which solves for y. What should be her next step?
3 x + 4 y = 8. 3 x minus 3 x + 4 y = 8 minus 3 x. 4 y = 8 minus 3 x.
Add 4y to both sides of the equation.
Subtract 4y from both sides of the equation.
Multiply both sides of the equation by 4.
Divide both sides of the equation by 4
Answer:
y= 2

Given the functions: f (x) = 2x to the 2nd power and
s (x) = 2 (x-3) What is the value of f(2) + s(-1)?
Answer:
0
Step-by-step explanation:
f(x)=2x²
s(x)=2(x-3)
Plugging in the numbers, we get:
f(2)= 2 * (2)²
f(2)= 2*4
f(2)= 8
s(-1)= 2*(-1-3)
s(-1)= 2*(-4)
s(-1)= -8
f(2) + s(-1) = 8 - 8 = 0
Find the coordinates of the image of (- 3, 4) under the transformation T- 2,3
A. (1, - 1)
B.(- 1, 1)
C.(5, - 7)
D.(- 5, 7)
Answer: D, (- 5, 7)
Step-by-step explanation:
Since the transformation is - 2, + 3 we just need to subtract 2 from the x value and add 3 to the y value.
- 3 - 2 = - 5
4 + 3 = 7
- 5, 7
20. At a track meet, teams get points for placing in the top 6 of each event. 1" place = 10 pts, 2nd place 8 pts, 30 = 6 pts, 4 = 4 pts, 5* = 2 pts, and 6h - 1 pt. At the last trackmeet, El Dorado scored 188 pts off of 38 scoring events. The number of 1 place finishes was equal to the number of 4 place finishes. The number of 2nd place finishes was half as many as the number of 3d place finishes. The number of 5 places finishes was equal to the sum of the number of 1" and 2nd place finishes. The number of 2nd place finishes was equal to the number of 6 place finishes. How many of each place did El Dorado have?

Evaluate - 4/8 ./. 8 2/3
Answer:
The answer is 13/3.
Step-by-step explanation:
8 2/3 is an improper fraction and is expressed as 26/3. CCF (copy, change, flip) is then applied to the division statement and 26/3 to becomes 4/8*26/3. The final answer is 104/24 which simples to 13/3.

What is the equation in point slope form of the line that passes through the point ( 2 , -4 ) and has a slope of 4?
Answer:
y + 4 = 4(x - 2)
Step-by-step explanation:
Point slope form: y - y1 = m(x - x1)
Where m = slope and (x1 , x2) = any given point.
We are given that the equation has a slope of 4 and passes through the point (2,-4)
So m = 4 and (x1,y2) = (2,-4)
We then plug in these values into the point slope form equation to get the answer.
y - y1 = m(x - x1)
m = 4 and (x1,y1) = (2,-4)
plug in values
y - (-4) = 4(x-2)
remove parenthesis on "-4" and change sign because the two negative signs cancel out and change into a positive sign
We end up with y + 4 = 4(x-2)

[tex]▪▪▪▪▪▪▪▪▪▪▪▪▪ {\huge\mathfrak{Answer}}▪▪▪▪▪▪▪▪▪▪▪▪▪▪[/tex]
The required equation is ~
[tex] \boxed{ \sf{y = \frac{x}{2} + 2 }}[/tex]
[tex] \large \boxed{ \mathfrak{Step\:\: By\:\:Step\:\:Explanation}}[/tex]
Let's find the slope of given line ~
[tex]y = - 2x + 5[/tex]comparing it with general slope - intercept form of line (y = mx + c) we get, m = -2 (that is slope of the line)
let the slope of the required line be n
And, now since the required line Is perpendicular to the given line. the product of their slopes is -1
that is ~
[tex] - 2 \times n = - 1[/tex][tex]n = \dfrac{ - 1}{ - 2} [/tex][tex]n = \dfrac{1}{2} [/tex]slope of required line is ~ 1/2
now, let's use the point - slope form of line to find the equation of required (perpendicular) line (using point (0 , 2) ~
that is ~
[tex]y - y_1 = m(x - x_ 1)[/tex]here, m = slope ~
[tex] y - 2 = \dfrac{1}{2} (x - 0)[/tex][tex]y - 2 = \dfrac{x}{2} [/tex][tex]y = \dfrac{x}{2} + 2[/tex]I hope it helps ~

Find the value of x so that the function has the given value.
Answer:
x = 10
Step-by-step explanation:
Given h(x) = 2x - 14 and h(x) = 6, then equating
2x - 14 = 6 ( add 14 to both sides )
2x = 20 ( divide both sides by 2 )
x = 10

solve using quadratic formula and include steps
2x^2 + 6x - 3 = 0
Answer:
x = (-3+√15)/2 or, x = (-3-√15)/2
Step-by-step explanation:
2x²+6x-3=0
Standard quadratic formula,
ax²+bx+c = 0
where,
x =(-b±[tex]\sqrt{b^{2}-4ac }[/tex])/2a ...............................(i)
Here,
a = 2
b = 6
c = -3
Putting the values in equation(i), we get,
x = (-6±[tex]\sqrt{6^{2} -4.2.(-3)}[/tex])/2.2
=(-6 ± √60)/4
=(-6 ± 2√15)/4
= (-3 ± √15)/2
Therefore, x = (-3+√15)/2 or x = (-3-√15)/2 :)
