Which circle shows an intercepted arc?
Answer:
B.
Step-by-step explanation:
An intercepted arc can therefore be defined as an arc formed when one or two different chords or line segments cut across a circle and meet at a common point called a vertex.
The required intercepted arc has been shown in circle B. Option D is the correct answer.
What is intercepted arc?In geometry, an intercepted arc is an arc of a circle that lies in the interior of an inscribed angle of the circle, and whose endpoints lie on the sides of the angle.
In other words, if we draw two rays originating from a point on the circle's circumference, the intercepted arc is part of the circle's circumference that lies between the two rays and is located inside the angle formed by the rays.
Here,
Following the above definition, Circle B consists of the intercepted arc.

[tex]f(x)=|3x-5|+7x[/tex]
[tex]g(x)=-2x+9[/tex]
To find:
The function [tex](f+g)(x)[/tex].
Solution:
We have,
[tex]f(x)=|3x-5|+7x[/tex]
[tex]g(x)=-2x+9[/tex]
We know that,
[tex](f+g)(x)=f(x)+g(x)[/tex]
On substituting the values of given functions, we get
[tex](f+g)(x)=|3x-5|+7x+(-2x+9)[/tex]
[tex](f+g)(x)=|3x-5|+7x-2x+9[/tex]
[tex](f+g)(x)=|3x-5|+5x+9[/tex]

f a1 = 7 and an = 5an-1 then find the value of a6
Answer:
a₆ = 21875
Step-by-step explanation:
Using the recursive rule and a₁ = 7 , then
a₂ = 5a₁ = 5 × 7 = 35
a₃ - 5a₂ = 5 × 35 = 175
a₄ = 5a₃ = 5 × 175 = 875
a₅ = 5a₄ = 5 × 875 = 4375
a₆ = 5a₅ = 5 × 4375 = 21875

A triangle with side lengths 3, 4, and 5 is a right triangle
by the converse of the Pythagorean Theorem.
What are the measures of the acute angles?
Answer:
36.87° and 53.13°
Step-by-step explanation:
the legs of the right triangle are 3 and 4 and the hypotenuse is 5
tan x = 3/4
x = arctan (3/4)
= 36.87° = measure on one acute angle
90 - 36.87 = 53.13° = measure of the other acute angle

-3(-2b + 5a + 7n - 10a + 6n +4a)
(please help me!!)
Answer:
6b + 3a - 39n
Step-by-step explanation:
Expanding using the distributive property :
-3(-2b + 5a + 7n - 10a + 6n +4a)
Multiply all values in the bracket by - 3
6b -15a - 21n + 30a - 18n - 12a
Collect like terms
6b - 15a + 30a - 12a - 21n - 18n
6b + 3a - 39n
After the community clean up, the ecology club collected all the empty drink containers. There were 40 more 5 cent deposit containers than 10 cent deposit containers. If the club received $24.80 from the recycling center, how many 5 cent deposit containers did they have?
The number of 5-cent deposit containers the ecology club collected is 192.
What are the linear equations that represent the question?a - b = 40 equation 1
0.05a + 0.1b = $24.80 equation 2
Where:
a = number of 5-cent deposit containers b = number of 10- cent deposit containers.How many 5-cent deposit containers were collected?
The first step is to multiply equation 1 by 0.1
0.1a - 0.1b = 4 equation 3
Add equation 3 and equation 1
$28.80 = 0.15a
a = $28.80 / 0.15
a = 192

You want to build a bicycle ramp that is 10 ft long and makes a 30 degree angle with the ground. What would be the height of the ramp?
PLZ HELP ME
Answer:
5.8 feet
Step-by-step explanation:
this problem uses a 30-60-90° triangle
the ratio of sides in a 30-60-90° triangle, respectively, are 1 : [tex]\sqrt{3}[/tex] : 2
let 'h' = height of ramp
we can use this proportion, then cross-multiply:
10/h = [tex]\sqrt{3}[/tex]/1
[tex]\sqrt{3}[/tex]h = 10
h = 10/[tex]\sqrt{3}[/tex]
after rationalizing the denominator we get:
(10[tex]\sqrt{3}[/tex] ) ÷ 3 which is approximately 5.8 feet
Using the trigonometric ratio, the height of the ramp is 5.77 feet.
Length of bicycle ramp = 10 feet
Angle with the ground = 30°
What is the sine of an angle?The tangent of an angle is the ratio of the opposite side to the adjacent of the triangle.
Suppose the height of the ramp is h.
So, [tex]tan30=\frac{h}{10}[/tex]
[tex]h=10tan30[/tex]
[tex]h=\frac{10}{\sqrt{3} }[/tex]
[tex]h=5.77[/tex] feet.
So, the height of the ramp is 5.77 feet.
Hence, using the trigonometric ratio, the height of the ramp is 5.77 feet.
