Answer:
Not really
Step-by-step explanation:
NOT NECESSARILY would a triangle be equilateral if one of its angles is 60 degrees. To be an equilateral triangle (a triangle in which all 3 sides have the same length), all 3 angles of the triangle would have to be 60°-angles; however, the triangle could be a 30°-60°-90° right triangle in which the side opposite the 30 degree angle is one-half as long as the hypotenuse, and the length of the side opposite the 60 degree angle is √3/2 as long as the hypotenuse. Another of possibly many examples would be a triangle with angles of 60°, 40°, and 80° which has opposite sides of lengths 2, 1.4845 (rounded to 4 decimal places), and 2.2743 (rounded to 4 decimal places), respectively, the last two of which were determined by using the Law of Sines: "In any triangle ABC, having sides of length a, b, and c, the following relationships are true: a/sin A = b/sin B = c/sin C."¹
Step-by-step explanation:
A triangle with three equal interior angles is called an equiangular triangle. In an equiangular triangle has three. equal sides, and it is the same as an equilateral triangle.
A bicycle depreciates in value each year. The value of the bicycle can be represented by the function y = 250(.85)6.
Identify the intial value and the decay rate.
Answer:
A=250
r= 15%
Step-by-step explanation:
Given data
We have the function
y = 250(.85)^6------------1
The given function is the same as the exponential decrease
function
P=A(b)^t---------------------2
Note
b= 1-r= 1-0.15
b= 0.85
When we compare both 1 and 2 above
A=250
r= 15%
What is the value of xin the solution to this system of equations?
y + 2x = -1
y =1/2x+4
Answer:
x = -2.
Step-by-step explanation:
y + 2x = -1
y = -2x - 1
y =1/2x+4
Subtracting the last 2 equations:
0 = -2x - 1/2x - 1 - 4
5 = - 5/2 x
x = 5 / -5/2
= 5 * 2 / -5 = -2.
3x + 4 = 5x -10 true or false this equation can be simplified combining like terms to become 8x + 4= -10

Answer:
72°
Step-by-step explanation:
The full plate has a central angle of 360°.
7/35 × 360° = 72°
Answer:
72°
Step-by-step explanation:
In order to find the value of the central angle, you must first determine what percentage of the plate was broken.
Since 7 out of the total 35 inches of circumference were broken, you divide 7 by 35 ([tex]7/35[/tex]) and get 0.2, which means 20% of the plate is broken.
Now, knowing that a circle consists of 360°, you need to find 20% of 360.
Use the formula [tex]\frac{percent}{100} =\frac{part}{whole}[/tex] .
[tex]\frac{20}{100}=\frac{x}{360}[/tex]
360 x 20 = 7200
7200 ÷ 100 = 72
x = 72
So, the central angle is 72°.

What is the surface area of a cube with a side length of 3/4 inch? Use the expression 6s 2, where is the side length of the cube
Answer: The surface area of the cube would be 3^3/4.
Step-by-step explanation:
A cube has 6 faces [ 6 surfaces ]. Each surface has a square shape.
The area of 1 surface= (side)^2= 3/4 · 3/4= 9/16 sqr.in.
Surface area of cube =9/16 · 1/6= 54/16.
divide both top and bottom (54 and 16) by 2. you should end up with 27/8.
27/8 = 3^3/4 sqr. in.
Hope this helps.

Which equation matches the function shown in the graph?
A. y=2sin(1/2x)+1
B. y=3sin(2x)
C. y=2sin(2x)+1
D. y=3sin(1/2x)
Answer:
the answer is A. y=2sin(1/2x)+1
Step-by-step explanation:
I input all four functions on desmos (a graphing calculator), and saw that A. y=2sin(1/2x)+1 was similar to the function shown in the graph
The function that matches the graph is y= 2 sin(1/2x) +1.
What is graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points.
Given:
let y = A sin ([tex]\omega[/tex]x + Ф)+ k
T= 4π, w= 2π/T = 1/2
Now, midline= 1/2( max + min)
=1/2(3-1)= 2/2
k=1
and, A= 3-1 = 2
So, y= 2 sin(1/2x + Ф) +1
as, Ф=0
So, y= 2 sin(1/2x) +1

Her last three attempts were 12 out of 20, 13 out of 20, and 15 out of 20. How far is her average free throw percentage from the needed free throw percentage to earn the chip? (round to the nearest whole number)
Answer:
83%
Step-by-step explanation:
12 + 13 + 15 = 40
16 x 4 = 64
16 x 3 = 48
40/48 = 0.833333333333
The temperature at midnight is -5°C and is expected to drop 12°
by sunrise. What is the expected temperature at sunrise?
Answer:
-17 degrees Celsius.
Step-by-step explanation:
If the temperature at midnight is -5, and it is supposed to drop 12 more by sunrise, the 12 degrees are subtracted from the initial temperature.
-5 - 12 = -17 degrees by sunrise.
Help pleaseee! This is for my geometry class!
Answer:
x = 98
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
Here n = 6 , then
sum = 180° × 4 = 720°
Sum the interior angles and equate to 720
x + 50 + 140 + 112 + x + x + 4 + 120 = 720, that is
3x + 426 = 720 ( subtract 426 from both sides )
3x = 294 ( divide both sides by 3 )
x = 98

Write an inequality that describes the graph
Answer:
x<4
Step-by-step explanation:
The arrow is facing left, making it less than. Next, the open circle on 4 means that it does not include 4, therefore the inequality is x<4.
The inequality that represents this situation is - ∞ ≤ x < 4.
What are inequalities and their types?Inequality is a relation that compares two numbers or other mathematical expressions in an unequal way.
The symbol a < b indicates that a is smaller than b.
When a > b is used, it indicates that a is bigger than b.
a is less than or equal to b when a notation like a ≤ b.
a is bigger or equal value of an is indicated by the notation a ≥ b.
Assuming the number line is represented by x.
An open circle on the right-hand side of the line at 4 represents it is less than 4.
We can also observe that the line is going infinitely in the direction of negative infinity.
So, this situation can be represented by an inequality of the form
- ∞ ≤ x < 4.

If you vertically stretch the square root parent function, F(x)= square roor x, by 7 units, what is the equation of the new function?
Answer:
g(x) = 7√x
Step-by-step explanation:
Parent function: f(x) = √x
Parent function vertically stretched by a factor of 7: g(x) = 7√x
The equation of the new function is 7√x.
What is a scale factor?Scale factor is that it is a number that multiplies times a given quantity to produce a smaller or larger version of the original number. The ratio of any two corresponding lengths in two similar geometric figures.
For the given situation,
The equation is F(x) = √x
The parent function is vertically stretched by 7 units.
So, the new function is
⇒ [tex]7(\sqrt{x} )[/tex]
⇒ [tex]7\sqrt{x}[/tex]

Step-by-step explanation:
rate of change =change of distance/ change of time
so if you look at the chart you can see these points: (2,50) and (6,150)
change of distance would be 150-50/ change of time which would be 6-2 which equals 100/4 which is 25, the rate of change.
