The angle measure of m∠DAR is 68°.
What is an Inscribed Angle?An inscribed angle is the angle that an arc at any point on the circle subtends.
Given information:
A circle is centered at 'A'.
m∠RBD = 34°.
Arc RD is given.
To find the angle measure m∠DAR:
m∠DAR is inscribed in a circle.
m∠DAR can be described as m∠DAR = m∠RBD
m∠DAR = 2 x 34°.
m∠DAR = 68°.
Therefore, m∠DAR = 68°.

There are 600 performers in a dance recital. The ratio of men to women is 4:6. How many men performers were in the dance recital
Answers
Answer: 240 men
Step-by-step explanation:
From the question, we are informed that there were 600 performers in a dance recital and that the ratio of men to women is 4:6.
Fraction of men at the recital = 4/10
Fraction of women at the recital = 6/10
The number of men performers that were in the dance recital will be:
= 4/10 × 600
= 240 men
There were 240 men at the recital.
12) If tan A=5/12 . find the value of (sin A + COS A) sec A.
Answers
Answer:
(sin(A) + cos(A)).sec(A) = 17/12
Step-by-step explanation:
tan(A) = 5/12
sin(A) = 5/13
cos(A) = 12/13
sec(A) = 1/(cos(A)) = 13/12
(sin(A) + cos(A)).sec(A) = (5/13 + 12/13).13/12
= 17/13.13/12
= 17/12

Solve 6x+3y=−1 for y
Answers
y=-2x-1/3 is the answer
The sets X and Y exists collectively referred to as the function's domain and codomain, respectively.
If the function be 6x + 3y = −1 then the value of y = (−1 - 6x) / 3.
What is meant by function?A function in mathematics from a set X to a set Y assigns exactly one element of Y to each element of X. The sets X and Y exists collectively referred to as the function's domain and codomain, respectively.
The characteristic that every input is associated to exactly one output defines a function as a relationship between a set of inputs and a set of allowable outputs.
A mathematical phrase, rule, or law establishes the link between an independent variable and a dependent variable (the dependent variable).
Let the given function be 6x + 3y = −1.
⇒ 3y = −1 - 6x
simplifying the above equation, we get
⇒ y = (−1 - 6x) / 3
Therefore, the value of y = (−1 - 6x) / 3.

Numerical expression:
Answer:
Answers
Answer:
Expression: 18 - 12 + 7. In 3 days, the temperature will be 13 degrees.
Step-by-step explanation:
The temperature is 18 degrees.
It will decrease 12 degrees after one day. So, it is 18 - 12.
Then it will increase by 7 degrees after another day. So, it is 18 - 12 + 7.
18 - 12 = 6. 6 + 7 = 13.
So, the expression is 18 - 12 + 7 and the answer is 13 degrees (i think)

Answer:Answer:
The answer is x^2 + x =420
Step-by-step explanation:
It is given that
The product of two consecutive integers is 420
Le x be the first number, then
second number is the next consecutive number of x which is (x +1)
The product of these numbers can be written as
x (x + 1) which is equal to 420
x (x + 1) = 420
x^2 + x = 420
So the quadratic equation is
x^2 + x = 420

Answers
Step-by-step explanation:
The triangle is isosceles, so the base angles are the same.
All three angles add up to 180°.
(6x + 4) + (6x + 4) + (18x − 8) = 180
30x = 180
x = 6
Answer:x=6
Step-by-step explanation:since those two sides shown are the same length, the missing angle is also 6x+4. the angles on a triangle always will equal 180. so you set the problem up as 6x+4+6x+4+18x-8=180. when you combine like terms it is then 30x=180. x=6

If you get 2 imaginary answers when using the quadratic formula, how does this relate to how many times (0, 1 or 2) a quadratic graph touches/crosses the x-axis?
Answers
Answer:Roots of a number indicates value where function will be zero. If an equation let's say
y = f(x) = x^2 -3x + 2 has two roots x = 1 and x =2 . Now if you will draw the graph, line will cross x-axis at 1 and 2 indicating y will become zero at 1 and 2. But if any equation has imaginary roots implies y will be never be zero for any real value of x and as we do not show imaginary number on a Cartesian plane we cannot make y =0 hence graph will never touch x-axis.
