Answer:
First pic
[tex]ratio = \frac{62.8}{2 0} \\ = 3.14[/tex]
Second pic
[tex] < c + 2x + (3x + 10) = 180 \\ < c = 180 - 3x - 10 - 2x \\ < c = 170 - 5x[/tex]
Answer:
Step-by-step explanation:
#1Circumference equation:
C = πdCircumference to diameter ratio is:
C/d = π = 3.14Same result comes from the tableCorrect choice is B#2Sum of angles of a triangle is 180°
m∠A + m∠B + m∠C = 180°A and C are equal angles as opposite sides are congruent.
2(3x + 10) + 2x = 1806x + 20 + 2x = 1808x = 160x = 20m∠C = 3*20 + 10 = 70°state the angle pair relationship then find the value of x
Answer:
x = 11
Step-by-step explanation:
The given angles are corresponding angles and are congruent, then
12x - 9 = 10x + 13 ( subtract 10x from both sides )
2x - 9 = 13 ( add 9 to both sides )
2x = 22 ( divide both sides by 2 )
x = 11

If (-10,8) is a point on the terminal side f a angle 0 in standard position what is the value of tan0?
Answer:
The value of the tangent is [tex]-\frac{4}{5}[/tex].
Step-by-step explanation:
Let be [tex]A(x,y) = (-10, 8)[/tex] on the terminal side of an angle in standard position and let be [tex]O(x,y)[/tex] the origin of the angle and the origin of the Cartesian plane. By definition of tangent, we make use of the following expression:
[tex]\tan \theta = \frac{y_{A}-y_{O}}{x_{A}-x_{O}}[/tex] (1)
Where:
[tex]x_{A}, x_{O}[/tex] - x-Coordinates of point A and point O.
[tex]y_{A}, y_{O}[/tex] - y-Coordinates of point A and point O.
If we know that [tex]x_{A} = -10, x_{O} = 0[/tex], [tex]y_{A} = 8[/tex] and [tex]y_{O} = 0[/tex], then the value of the tangent is:
[tex]\tan \theta = \frac{y_{A}-y_{O}}{x_{A}-x_{O}}[/tex]
[tex]\tan \theta = \frac{8-0}{-10-0}[/tex]
[tex]\tan \theta = -\frac{4}{5}[/tex]

what is the rate of change ?
is the function linear or non linear ? why ?
Answer:
Step-by-step explanation:
Are you in Calculus? These are calculus concepts!
To calculate the rate of change here you must specify an interval, e. g., "what is the rate of change on the interval (0, 3)?"
If you know calculus: The 'rate of change' on the interval (a, b) is
f(b) - f(a)
r. of c. = --------------------
b - a
Have you used this formula before?
Because of the 'x^2' term this is NOT a linear function.
If you want more explanation, provide an interval on which you want the average rate of change and ask specific questions of your own.

Jacob deposits $60 into an investment account with an interest rate of 4%, compounded annually. The equation,
y = 60(1 + 0.04)x, can be used to determine the number of years, x, it takes for Jacob's balance to reach a certain amount of money, y. Jacob graphs the relationship between time and money.
1. What is the y-intercept of Jacob's graph?
2. If Jacob doesn't deposit any additional money into the account, how much money will he have in eight years? Round your answer to the nearest cent.
Answer:
1. 60 is his y-intercept
2. $82.11 in his account after 8 years
Answer:
The y-intercept of Jacob's graph is $60, which represents the initial amount of money he deposited into the account.
If Jacob doesn't deposit any additional money into the account, the amount of money he will have in eight years can be found by plugging in x=8 into the equation y = 60(1 + 0.04)^x and evaluating:
y = 60(1 + 0.04)^8
y ≈ $82.08
So the answer to the second question is that Jacob will have approximately $82.08 in the account after eight years, assuming he doesn't deposit any additional money into the account.
Hope this helps,

Yesenia has a 13 ft ladder that she placed against a
wall. How far up the wall will the ladder reach when the
base of the ladder is 5 ft from the wall?
Answer:
12 ft
Step-by-step explanation:
Using formula (pythagorean theorem)
a² + b² = c²
Where :
13 = c
and 5 = a
5² + b² = 13²
25 + b² = 169
169 - 25 = b²
144 = b²
Sq root b = 12
It will reach up 12 ft.

How do I find the answer
Answer:
x = 95 degrees
Step-by-step explanation:
First find the missing angle next to 142 (we will call it y)
y +142 = 180
subtract 142 from both sides
y = 38 degrees
then we know a triangle must have 180 degrees
so
47+38+x = 180
subtract 47 and 38 from 180
x = 95
hope this helps and makes sense :)
