Complete the triangle. Find all missing sides and angles. Round to the nearest tenth. Triangle DEF; DE=23 and FE=25
DF=?
Angle F=?
Angle E=?
help pls!!
Answer:
DF= 9.8
Angle F= 42.6 degrees
Angle E= 23.1 degrees
Step-by-step explanation:
so for the sides we can use the pythagorean theorem
23^2+b^2=25^2
23 squared is 529 and
25 squared is 625
529+b^2=625
subtract 529 from both sides
b^2=96
the square root of 96 is ~9.8
b=9.8
To find the angles you use sin, cos, or tan. Now that we know all three sides it doesn't matter which one you use so... pick your favorite.
sinf=23/25
f= ~66.9 degrees
tane= 23/25
e= ~23.1
Simplify the following expression.
(2d – 3)(2d – 3)
Answer:
[tex]4d^2-12d+9[/tex]
Step-by-step explanation:
Okay, so lets break this problem down. We are given two binomials to multiply together. The simplest way to get our answer is by using the F.O.I.L method. This is done by the following:
F: First
O: Outer
I: Inner
L: Last
To say simply, the first term in the first parenthesis or 2d will be multiplied the first term in the second parenthesis 2d.
Here are the steps:
[tex](2d-3)(2d-3)\\2d*2d=F\\2d*-3=O\\-3*2d=I\\-3*-3=L\\Now:\\2d*2d=4d^2\\2d*-3=-6d\\-3*2d=-6d\\-3*-3=9\\$4d^2-6d-6d+9\\Combine Terms\\4d^2-12d+9[/tex]

Answer:
15% markdown
Step-by-step explanation:
In order to find the markdown, take the lowered price and place it in a fraction as the numerator, and the initial price as the denominator. This looks like:
[tex]\frac{828.75}{975}[/tex]
with this fraction, we're going to multiply it by 100, with an equation looking like this,
[tex]\frac{828.75}{975}[/tex]×[tex]\frac{100}{1}[/tex]
once we multiply(typically using a calculator, though manually is possible of course) we get 85.
In order to find the markdown price however, we need to subtract 85 from 100, getting 15. This is the markdown price, because it's the percentage of the initial whole that the price went down by. Can check by finding 15% of 975, which is 828.75

How are iteration and composition functions related?
Answer:
they are related by ________
Step-by-step explanation:
Answer:
In mathematics, an iterated function is a function X → X (that is, a function from some set X to itself) which is obtained by composing another function f : X → X with itself a certain number of times. The process of repeatedly applying the same function is called iteration.

PLS HELP ME ASAP PLS ILL MARK BRAIN
Answer:
Step-by-step explanation:
1). Let the circumference C and area A of the circle are proportional,
C ∝ A
C = kA
Here k = proportionality constant
k = [tex]\frac{C}{A}[/tex]
From the given table,
For C = 25 cm, A = 50 cm²
Then the value of k = [tex]\frac{25}{50}[/tex]
k = [tex]\frac{1}{2}[/tex]
For C = 50 cm, A = 201 cm²
k = [tex]\frac{50}{201}[/tex] ≈ [tex]\frac{1}{4}[/tex]
In both the cases proportionality constant is giving the different values.
Therefore, Circumference and Area of the circular objects are not proportional.
2). If A = [tex]\frac{1}{2}\times r\times C[/tex]
Then this equation will be true for all the values of r and C given in the table.
For r = 4 cm and C = 25 cm
A = [tex]\frac{1}{2}\times 4\times 25[/tex] = 50 cm²
For r = 8 cm and C = 50 cm
A = [tex]\frac{1}{2}\times 8\times 50[/tex]
A = 200 cm²
True for all values of 'r' and 'C'.

Answer:
The answer is 3 ≤ y ≤ 8.
Step-by-step explanation:
When we want to find range of a function, we have to look at maximum and minimum value of y-axis.
So the range of this function is 3 ≤ y ≤ 8.
ΔA’B’C’ is a reflection of ΔABC. Which best describes the reflection?
A coordinate plane showing triangles A B C and A prime B prime C prime. The coordinates of the first figure are A negative 2 comma 2, B zero comma 4, and C 2 comma 2. The coordinates of the second figure are A prime 8 comma 2, B prime 6 comma 4, and C prime 4 comma 2.
a.)A reflection over the line x = 2
b.)A reflection over the line y = 3
c.)A reflection over the line x = 3
d.)A reflection over the y-axis
The statement that best describes the reflection of ΔABC is "A reflection over the line x = 3".
What is a triangle?A triangle is a polygon with 3 sides. Also, It has three vertices.
If we plot the two triangles on the graph,
A = (-2,2)
B = (0,4)
C = (2,2)
A' = (8,2)
B' = (6,4)
C' = (4,2)
We will find that the two of the triangles are identical therefore, the two triangles are reflections of each other, and the distance between the points
C and C' is of 2 units, therefore, if we draw the line between the two points, C and C' such that the line is parallel to the y-axis and lies at x=3, then ΔA’B’C’ will be a reflection of ΔABC.
Hence, the statement that best describes the reflection of ΔABC is "A reflection over the line x = 3".

Find the 13th term of the geometric sequence 3, -15, 75, ...
the terms of geometric sequence are 3, -15, 75
given,
1st term (a) = 3
second term (t2)=-15
common ratio (r) = t2/t1
=-15/3
=-5
then
t13= ar^n-1
=3×(-5)^13-1
=3×244140625
=3×244140625
=732421875.
The [tex]13^{th}[/tex] term of the geometric sequence is - 732421875.
A geometric sequence is given ; 3 , -15 , 75....
We have to find the [tex]13^{th}[/tex] term of the geometric sequence.
What is the formula for calculation of nth term of geometric Sequence ?
The formula for calculation of nth term of geometric progression is [tex]a_{n}[/tex] = [tex]a_{1}[/tex] × [tex](r)^{n-1}[/tex] where r is the common ratio of geometric sequence.
Given geometric sequence is 3 , -15 , 75....
and
Common ratio is r.
i.e., r = -15 ÷ 3 = -5
∵ [tex]n^{th}[/tex] term of a geometric sequence is given by ;
[tex]a_{n}[/tex] = [tex]a_{1}[/tex] × [tex](r)^{n-1}[/tex]
where [tex]a_{1}[/tex] is the first term.
So,
[tex]13^{th}[/tex] term of the geometric sequence will be ;
[tex]a_{13}[/tex] = 3 × [tex](-5)^{12}[/tex]
[tex]a_{13}[/tex] = - 732421875
Thus , the [tex]13^{th}[/tex] term of the geometric sequence is - 732421875.
