Identify the correct phrase to complete the statement.
A central angle has a measure of 1 radian if:
A. the length of the arc it intercepts is twice the length of the radius.
B. the central angle is 90°.
C. the length of the arc it intercepts is the same as the length of the
radius.
O D. the radius has a length of 1
Answer:
C.) the length of the arc it intercepts is the same as the length of the radius
Step-by-step explanation:
The length of the arc it intercepts is the same as the length of the
radius option (C) is correct.
What is a circle?It is defined as the combination of points that, and every point has an equal distance from a fixed point (called the center of a circle).
As we know, the relationship between arc length and the central angle:
s = rθ
[tex]\rm \theta = \dfrac{s}{r}[/tex]
Where 's' is the arc length and θ is the central angle, r is the radius of the circle.
If θ = 1 radian
Then,
s = r
Thus, the length of the arc it intercepts is the same as the length of the
radius option (C) is correct.

Write an expression to describe the sequence below. Use n to represent the position of a term in the sequence, where n = 1 for the first term. -91, -194, -291, -388
Answer:
[tex]T_n = -97n[/tex]
Step-by-step explanation:
The actual sequence is: -97, -194, -291, -388
Required
Determine the nth term
nth term of an arithmetic progression is:
[tex]T_n = T_1 + (n - 1)d[/tex]
Where
[tex]T_1 = First\ Term = -97[/tex]
[tex]d = Common\ Difference = -194 - (-97) =-97[/tex]
So:
[tex]T_n = T_1 + (n - 1)d[/tex] becomes
[tex]T_n = -97 + (n - 1) * -97[/tex]
[tex]T_n = -97 -97n + 97[/tex]
Collect Like Terms
[tex]T_n = -97n + 97-97[/tex]
[tex]T_n = -97n[/tex]
Hence, a term of the sequence is:
[tex]T_n = -97n[/tex]

(5x-1)(3x+2)
(if you don't want to do all of this you can use
Step-by-step explanation:
((3•5x2) + 7x) - 2
Factoring 15x2+7x-2
The first term is, 15x2 its coefficient is 15 .
The middle term is, +7x its coefficient is 7 .
The last term, "the constant", is -2
Step-1 : Multiply the coefficient of the first term by the constant 15 • -2 = -30
Step-2 : Find two factors of -30 whose sum equals the coefficient of the middle term, which is 7 .
-30 + 1 = -29
-15 + 2 = -13
-10 + 3 = -7
-6 + 5 = -1
-5 + 6 = 1
-3 + 10 = 7 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -3 and 10
15x2 - 3x + 10x - 2
Step-4 : Add up the first 2 terms, pulling out like factors :
3x • (5x-1)
Add up the last 2 terms, pulling out common factors :
2 • (5x-1)
Step-5 : Add up the four terms of step 4 :
(3x+2) • (5x-1)
Which is the desired factorization
Answer:
(5x-1)(3x+2)

Write y – 3 = 23 (x – 2) in standard form. PLEASE HELP BEST ANSWER AND EXPLANATION WILL GET BRAINLIEST!!
Answer:
23x -y = 43
Step-by-step explanation:
in slope intercept form, we have y=mx+b where m=slope, b= y intercept
first let's simplify the expression 23(x-2)
y-3 = 23x - 23*2
y-3 = 23x - 46
now add 3 to both sides to move numbers to the right hand side
y -3 +3 = 23x -46 +3
y = 23x - 43
convert to standard form by having x and y on one side, numbers on the other.
add 43 to both sides
y+43 = 23x
subtract y from both sides
43 = 23x - y

If A = 117 degrees, B = 12 degrees, and b = 12, find a. Round to the nearest tenth.
Answer:
a = 51.4Step-by-step explanation:
sinA = sinB
a b
sin(117) = sin(12)
a 12
a * sin(12) = 12 * sin(117)
a = 12 * sin(117)
sin(12)
a = 51.4

1) the sum of 8 and t
3) the product of 5 and b
Step-by-step explanation:
When we say sum we are referring to addition.
And a number and a variable(letter) can't be added. So the sum of 8 and t can't be added.
The sum of 8 and t is;
8+t
When we talk about product or finding the product of a number we are referring to the number we get after multiplying two or more numbers.
And note that with multiplication, a number and a variable(letter) can be multiplied.
The product of 5 and b is;
5×b=5b
What is this
y=3x-4
Answer:
4/3 or 1.3
Step-by-step explanation:
y= 3x-4
To find x- intercept/zero, Substuite y=0.
0= 3 x -4
Move the variable to the left-hand side and change its sign
-3x= -4
Divide both sides of the equation by -3
x= 4/3
(1.3 as a decimal)
Walkway Over the Hudson, a bridge that crosses the Hudson River in Poughkeepsie, is 2.063
kilometers long. Anping Bridge, which was built in China 850 years ago, is 2.07 kilometers long.
a. What is the total span of both bridges?
Show your thinking
b. How much longer is the Anping Bridge
than the Walkway Over the Hudson?
Answer: 4.126 km
Step-by-step explanation:
First, We have to find total span of both bridges
As Question indicates 'total' ,that is, we have to find bridge length in total ( You can join Bridges to have better understanding)
Now, Walkway over hundson Bridge length= 2.063 km
Amping bridge length= 2.07 km
So, Total span of both bridges = 2.063+2.07 = 4.133 km
b) Now Leah wanna walk across and back on walkway over hudson ,that is, she wanna return to starting point from where she walk forth
So,that means, she walk double distance of length of walkway over hudson
So, total distance = 2× 2.063
= 4.126 km

Answer:
C. y + 7 = -7(x - 3)Step-by-step explanation:
The equation of a line is:
y - y₀ = m(x - x₀)
where m is the slope and (x₀, y₀) is the point which the line passes through
The product of slopes of two perpendicular lines is -1
so if given lines slope is ¹/₇ them:
¹/₇·m = -1
m = -7
(3, -7) ⇒ x₀ = 3, y₀ = -7
Therefore:
y - (-7) = -7(x - 3)
y + 7 = -7(x - 3)
Solve the exponential equation: 6–2x = 62 – 3x
Question 1 options:
A)
4
B)
–2
C)
3
D)
2
Answer:
x = 56
Step-by-step explanation:
Collect like terms:6 - 2x = 62 - 3x
-2x + 3x = 62 - 6
1x = 56
x = 56
Check your answer:6 - 2(56) = 62 - 3(56)
6 - 112 = 62 - 168
-106 = -106
