Answer:
s = 5/4 pi
Step-by-step explanation:
A = 25π cm2
Theta = pi/4
A = pi r^2 = 25 pi
Divide each side by pi
r^2 = 25
Taking the square root of each side
sqrt(r^2) = sqrt(25)
r = 5
The arc length is
s = r * theta where theta is in radians
s = 5 * pi/4
s = 5/4 pi
if the string forms a straight line, how high is the kite above the ground?
Answer:
102.44 feet
Step-by-step explanation:
This kite and its height forms a right triangle. In a right triangle, the sine of an angle is the length of the opposite side divided by the length of the hypotenuse, which in this case is 130 feet. Therefore:
[tex]\sin 52= \dfrac{x}{130}[/tex]
[tex]x=\sin 52 \times 130\approx 102.44[/tex] feet. Hope this helps!
Mrs. Jacobsen asked her students to write a word problem that describes the graph below. Which word problem accurately describes the graph?
a. Jamie has $8, and she pays $2 per day to ride the bus.
b. Melinda has $4 and earns $2 allowance per day doing chores.
c. Carrina has $8, and she earns $2 per day babysitting.
d. Louise has $4, and she pays $2 per day for school lunch.
Answer:
The answer is a. Jamie has $8, and she pays $2 per day to ride the bus.
Step-by-step explanation:
When looking at the graph, you can see that you start with $8. You lose $2 per day. That is why you are losing money per day.
Answer:
A
Step-by-step explanation:
When you look at the graph you can see the she originally has $8, and then her mone decreases by 2 a day, which is due to bus ride fees.

For what values of m, the relation K= {(2.3m + 45, 0), (−67m − 8.9, 0)} is a function?
Answer:
The relation is a function for all m-values different than -53.9/69.3Step-by-step explanation:
If the relation is a function, then we can say that
[tex]2.3m+45\neq -67m-8.9[/tex]
Solving for [tex]m[/tex], we have
[tex]2.3m+67m\neq -8.9-45\\69.3m \neq -53.9\\m \neq - \frac{53.9}{69.3}\\[/tex]
Therefore, the relation is a function for all m-values different than -53.9/69.3

The point-slope form of a line is y-y1 = m(x-x1), where m is the slope and x1 is a point on the line.
A. True
B. False
Answer:
False.
Step-by-step explanation:
A point on the cordinate plane needs an x-coordinate and a y-coordinate.
The point is (x1, y1) not just x1.
The statement is true because the point-slope form of a line is y - y₁ = m(x -x₁), where m is the slope and x1 is a point on the line.
What is the Point-slope form?The equation of the straight line has its slope and given point.
If we have a non-vertical line that passes through any point(x1, y1) has gradient m. then general point (x, y) must satisfy the equation
y-y₁ = m(x-x₁)
Which is the required equation of a line in a point-slope form.
The point-slope form of a line is y - y₁ = m(x -x₁), where m is the slope and x1 is a point on the line.
Hence, the statement is true.

So this means the functions should be multipled and both evaluated at x = 5
The value of the composition of functions ( g o f ) ( 5 ) = 4
What is Composition of functions?Evaluation of a function at the value of another function is known as Composition of function. A function composition is a process in which two functions, f and g, form a new function, h, in such a way that h(x) = g(f(x)). This signifies that function g is being applied to the function x. So, in essence, a function is applied to the output of another function.
Given data ,
Let the first function be represented as h ( x )
Now , the value of h ( x ) is
h ( x ) = x - 7
Let the second function be represented as g ( x )
Now , the value of g ( x ) is
g ( x ) = x²
Now , the composition of function ( g o f ) ( 5 ) is given by
The value of f ( 5 ) = 5 - 7 = -2
Now , the value of g ( -2 ) is
g ( -2 ) = ( -2 )²
g ( -2 ) = 4
Hence , the composition of function is solved and the value is given by A = ( g o f ) ( 5 ) = 4

Answer:
y=(8/5)x-(24/5)
Step-by-step explanation:
lets find the slope
m=(y2-y1)/(x2-x1)
m=(8-0)/(8-3)
m=8/5
y=(8/5)x+b
lets find b, the y-int by plugging in a point
0=(8/5)*3+b
0=24/5+b
b=-24/5
y=(8/5)x-(24/5)

I think we're probably talking about a right triangle. So just find the adjacent side and the hypotenuse.
Step-by-step explanation:
Once we are considering [tex]x \in \mathbb{R}[/tex], the range of [tex]\text{cos}(x)[/tex] is [tex][1, -1][/tex]. Therefore, [tex]$\frac{42}{41} $[/tex] is not true.
In this exercise, we may have
[tex]$\text{cos}(x)=\frac{x}{r} =\frac{x}{\sqrt{x^2 +y^2} } $[/tex]
Considering the trigonometric functions beyond the unit circle.
Or considering the definition in the right triangle:
[tex]$\text{cos}(x)=\frac{\text{adjacent}}{\text{hypotenuse}} $[/tex]

What is m∠A? Enter your answer in the box.
Answer:
∠A is 118 degrees
Step-by-step explanation:
every triangle is 180 degrees
(3x+13) + (x-8) +(x) = 180
simplify
5x + 5 = 180
-5 = -5
5x = 175
175 divided by 5 is 35
so x= 35
∠A= 3(35) + 13
3 times 35 is 105
105 + 13 = 118
so ∠A is 118 degrees

Step-by-step explanation:
The piece that isn't marked with xs is 90 degrees marked by the square symbol representing a right angle.
Full circle = 360 degrees
360 degrees - 90 degrees = 270 degrees
Now, if we add all the like terms we have 4 x's in total. This is becauswe 3x + another x = 4x.
So, we need to divide 270 by 4. We get 67.5 degrees.

Kim’s family spends $62.50 on dinner. They leave an 18% tip. How much is their total bill after tip?
Answer:
51.25
Step-by-step explanation:
Multiply 62.5 by .18. You get 11.25. Subtract that from 62.5 and you get 51.25.
Answer:
Multiply the price with the tip rate
18% = 0.18
62.5 x 0.18 = 11.25
that is the tip. We add that on to find the total price
62.5 + 11.25 = 73.75
