Answer:
38°, 66°, 76°acute triangleStep-by-step explanation:
Let x represent the smallest angle. Then the other two angles are (x+28) and 2x. Their sum is ...
x + (x+28) +(2x) = 180
4x = 152 . . . . subtract 28
x = 38 . . . . . . .divide by 4
x+28 = 66 . . . find the other angles
2x = 76
The three angles are 38°, 66°, 76°. The largest angle is acute, so it is an acute triangle.

Every month, your cell phone plan costs $90 and gives you unlimited talk, unlimited text messages, and 4 GB of data. The cell phone company also charges $20 for each gigabyte over 4 GB of data. How much will you be charged if you use 10 GB of data?
Answer: You will be charged $ 210 for 10 GB of data.
Step-by-step explanation:
Given : Cost of cell phone plan = $90
Additional charge over 4GB for each GB = $20
If 10 GB data is used , then after 4 GB you need to pay for 6 additional GB (10-4=6)
Total charge = (Cost of cell phone plan)+ (Additional charge) x (Number of gigabytes over 4 GB)
i.e. Total charge = $(90+20(6))
= $ (90+120)
= $ 210
Hence, you will be charged $ 210 for 10 GB of data.

What is X? 8(5x-5)=8(5x-5)
Answer:
An infinite number of solutions.
Step-by-step explanation:
When you try to solve for x, the result is 0 = 0.
This means that for any value you plug in for x, the result will always be equal to each other, therefore making the equation true.
Robin reads 5 pages of a book in 4 minutes. Based on this rate, what is the total number of minutes it will take Robin to read 200 pages?
Answer: 160 minutes
Step-by-step explanation: 200 divided by 5 is 40, then 40 times 4 is 160
Division is one of the four fundamental arithmetic operations. The time it will take Robin to read 200 pages of the book at the same rate is 160 minutes.
What is Division?The division is one of the four fundamental arithmetic operations, which tells us how the numbers are combined to form a new one.
Given that it takes Robin 4 minutes to read 5 pages of a book. Therefore, the rate at which Robin reads a page of the book is,
Rate at which Robin reads = 4 minutes/5 pages = 0.8 minutes per page
Now, to know the time it will take for Robin to read the book of 200 pages at the same rate can be found by multiplying the number of pages by the rate of reading. Therefore, the rate at which Robin reads is,
Time to read 200 pages = 0.8 minutes per page × 200 pages
= 160 minutes
Hence, the time it will take Robin to read 200 pages of the book at the same rate is 160 minutes.

Answer:
heres an example: Replace all x's in
g(x)
with the function f(x) to get
g(f·x)=(x+3)2
Explanation:
g(f·x)
means that you replace all x's in
g(x)
with the function
(f·x)
The easiest way to do this is rewrite
g(x)
replacing all x's with a blank set of parenthesis, like this
-g(f·x)=(x)2
Now place the function into the parenthesis.
(f·x)
g(f·x)=(x+3)2

Is there a way to solve this equation without Calculus concepts? I am enrolled in Geometry and this is extra credit and I'm having a hard time understanding this. Please mind how stupid I may sound if I said something wrong.
Step-by-step explanation:
ω = ω₀ + αt
θ = ω₀ t + ½ αt²
We need to eliminate t from the system of equations. Solve for t in the first equation, then substitute it into the second equation.
t = (ω − ω₀) / α
θ = ω₀ (ω − ω₀) / α + ½ α ((ω − ω₀) / α)²
θ = ω₀ (ω − ω₀) / α + ½ (ω − ω₀)² / α
αθ = ω₀ (ω − ω₀) + ½ (ω − ω₀)²
αθ = ω₀ω − ω₀² + ½ (ω² − 2ω₀ω + ω₀²)
αθ = ω₀ω − ω₀² + ½ ω² − ω₀ω + ½ ω₀²
αθ = ½ ω² − ½ ω₀²
2αθ = ω² − ω₀²

Complete Question
A long jump competition was held at Barangay Mathalino John Mark
jumped 2/3 of 6 3/5 meters of the field. How far did John Mark jump?
Answer:
4 2/5 meters
Step-by-step explanation:
We are told:
John Mark jumped 2/3 of 6 3/5 meters of the field.
The distance John jumped us calculated as:
2/3 × 6 3/5 meters
Converting 6 3/5 meters to mixed fraction
= 33/5 meters
Hence, John jumped
=2/3 × 33/5 meters
= 22/5 meters
= 4 2/5 meters

solution of the linear equation 3x + 4y= 10
Add -4y to both sides.
3x + 4y + −4y = 10 + −4y
3x = −4y + 10
Divide both sides by 3.
3x /3 = −4y + 10 /3
x= −4 /3 y + 10 /3
Answer: x= −4 /3 y + 10 /3

Which phrase describes the solution set for this function?
f(x) = 2(x - 1)2 + 4
A.
one real solution and one complex solution
B.
two complex solutions
O C.
two real solutions
D.
one real solution
Note: The function is not an equation. I will form and solve an equation to answer the question.
Answer:
C. Two real solutions
Step-by-step explanation:
We have the following function:
f(x)=2(x-1)^2+4
It does not form an equation to solve, and therefore, there are no 'solutions'. We must equate the function to something to set a condition and solve it. We'll complete the equation.
Solve for x when:
f(x)=12
Substituting the function:
2(x-1)^2+4=12
Subtracting 4:
2(x-1)^2=8
Dividing by 2:
(x-1)^2=4
Taking square root:
x-1=\pm\sqrt{4}
Solving:
x=1\pm2
We have two real solutions x=3 and x=-1
Note if we had equated to 4, then the equation would have had only one real solution, and if we had equated to 0, we would have two complex solutions.

Gianna is substituting t = 2 and t = 7 to determine if the two expressions are equivalent. 5 (2 t + 3) 5 t + 25 Which statement is true? Both expressions are equivalent to 35 when t = 2. Both expressions are equivalent to 85 when t = 7. Both expressions are equivalent to 60 when t = 7. The expressions are equivalent.
Answer:
Both expressions are equivalent to 35 when t = 2
Step-by-step explanation:
Given
Expression 1: 5(2 t + 3)
Expression 2: 5t + 25
When t = 2
5 (2 t + 3)
= 5(2*2 + 3)
= 5(4 + 3)
= 5(7)
= 35
5t + 25
= 5*2 + 25
= 10 + 25
= 35
When t = 7
5(2 t + 3)
= 5(2*7 + 3)
= 5(14 + 3)
= 5(17)
= 85
5t + 25
= 5*7 + 25
= 35 + 25
= 60
Both expressions are equivalent to 35 when t = 2
Answer:
Both expressions are equivalent to 35 when t = 2.

Step-by-step explanation:
Answer:
f(x)=23/8
Step-by-step explanation:
To find horizontal asymptotes: If the degree (the largest exponent) of the denominator is bigger than the degree of the numerator, the horizontal asymptote is the x-axis (y = 0). If the degree of the numerator is bigger than the denominator, there is no horizontal asymptote.

The function f(x) is graphed on the coordinate plane.
What is f(−4)?
Answer:
f(-4) = 4
Step-by-step explanation:
Let the equation of the function is,
f(x) = mx + b
where m = slope of the line
b = y-intercept of the line
From the graph attached,
Slope = [tex]\frac{\text{Rise}}{\text{Run}}[/tex] = [tex]\frac{-2}{4}[/tex]
Slope 'm' = [tex]-\frac{1}{2}[/tex]
y-intercept 'b' = 2
Therefore, function will be,
f(x) = [tex]-\frac{1}{2}x+2[/tex]
For x = -4,
f(-4) = [tex]-\frac{1}{2}(-4)+2[/tex]
= 2 + 2
= 4
Which is true from the graph.
