Step-by-step explanation:
The center of the circle is G. Below is a student's work to find the
value of x. Explain the error and find the correct value of x.
Answers
Answer:
The error are
1) The use of the angle addition postulate, for [tex]m \widehat{ACD}[/tex]
2) The assumption that [tex]m \widehat{BC}[/tex] = 90°
The vertical angle property between [tex]m \widehat{CD}[/tex] and [tex]m \widehat{FA}[/tex] should be used to find 'x'
x = 5
Step-by-step explanation:
From the drawing of the circle, we are given;
AD = A diameter of the circle
∴ [tex]m \widehat{ACD}[/tex] = 180°
By angle addition postulate, we have;
[tex]m \widehat{ACD}[/tex] = [tex]m \widehat{AB}[/tex] + [tex]m \widehat{BC}[/tex] + [tex]m \widehat{CD}[/tex]
By substitution property of equality, we have;
180° = [tex]m \widehat{AB}[/tex] + [tex]m \widehat{BC}[/tex] + [tex]m \widehat{CD}[/tex]
[tex]m \widehat{AB}[/tex] = 5·x°
[tex]m \widehat{BC}[/tex] = Not given
[tex]m \widehat{CD}[/tex] = 15·x°
However;
[tex]m \widehat{CD}[/tex] is the vertically opposite angle to [tex]m \widehat{FA}[/tex]
∴ [tex]m \widehat{CD}[/tex] = [tex]m \widehat{FA}[/tex] = (16·x - 5)°
[tex]m \widehat{CD}[/tex] = 15·x° = (16·x - 5)°
15·x° = (16·x - 5)°
∴ 5 = 16·x° - 15·x° = x
x = 5
[tex]m \widehat{BC}[/tex] = 180° - ([tex]m \widehat{AB}[/tex] + [tex]m \widehat{CD}[/tex]) = 180° - (15·x° + 5·x°) = 180° - (20·x°)
[tex]m \widehat{BC}[/tex] = 180 - (20×5)° = 80°
[tex]m \widehat{BC}[/tex] = 80°
The error are the use of the angle addition postulate, for [tex]m \widehat{ACD}[/tex], and the assumption that [tex]m \widehat{BC}[/tex] = 90° rather than the vertical angle property between [tex]m \widehat{CD}[/tex] and [tex]m \widehat{FA}[/tex] in trying to find 'x', from which x = 5.

2. What is the coordinate of the final image of vertex T
after the triangle is translated 3 units to the left and 2
units up?
Please help with number 2
Answers
Answer:
We have the coordinates of vertex T after the translation as (-5,0)
Step-by-step explanation:
Firstly, we get the coordinates of vertex T
we have this as;
(-2,-2)
Translating to the left means we are going to subtract the specific units from the x-coordinate
2 units up means we are going to add to the y-coordinate value
So, we have it that;
(-2-3, -2+ 2) = (-5,0)
The points (80,20) and (120,30) form a proportional relationship. What is the slope of the line that passes through these points
A. 1/4
B. 4
C. 10
D. 40
Answers
Answer:
[tex]\frac{1}{4}[/tex]
Step-by-step explanation:
Slope = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex] where the given points are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]
Plug the given points (80,20) and (120,30) into the equation
[tex]\frac{y_2-y_1}{x_2-x_1}\\= \frac{30-20}{120-80}\\= \frac{10}{40}\\= \frac{1}{4}[/tex]
Therefore, the slope of the line that passes through these points is [tex]\frac{1}{4}[/tex].

Ayden wants to sell a total of $150 worth of candy bars for his school fundraiser. Each candy bar costs $1.50. How many candy bars will he have to sell in order to meet his goal?

Hey!

Ayden wants to sell a total of $150 worth of candy bars for his school fundraiser. Each candy bar costs $1.50. How many candy bars will he have to sell in order to meet his goal?
--------------------------------------------------------------------------------------------------------------
We can create an algebraic Equation to solve this.
- We know that Each Candy Bar costs $1.50.
-We multiply the Amount of Candy Bars with the price.
-We know the profit should be $150
⇒ 1.50x = 150
-Divide by 1.50 on both sides
⇒ 1.50x/1.50 = 150/1.50
-Simplify
⇒ x = 100
==================================================================
Hope I Helped, Feel free to ask any questions to clarify :)
Have a great day!

Answer:
In total, the amount of milk every kid combined drank is 672 ounces.
Step-by-step explanation:
If four kids drank 24 ounces of milk for seven days, you would solve it as follows:
First, the amount all the kids drink in one day combined is 96 ounces.
If they drink 96 per day, and they do so for a week (7 days), then that is 96 × 7 because its 96 seven times.
7 × 96 = 672

If f(x) = x2 and g(x) = 3x + 1, then g(f(2))= ?
Answers
Answer:
The value of g[f(2)] = 13
Step-by-step explanation:
Given functions:
f(x) = x²
g(x) = 3x + 1
Find:
The value of g[f(2)]
Computation:
f(x) = x²
By putting x = 2 in f(x)
f(x) = x²
f(2) = 2²
f(2) = 2 × 2
f(2) = 4
So the value of f(2) = 4
Value of f(2) putting in g(x)
g(x) = 3x + 1
g(x) = 3x + 1
g[f(2)] = 3[f(2)] + 1
We know that f(2) = 4
So,
g[f(2)] = 3[f(2)] + 1
g[f(2)] = 3[4] + 1
g[f(2)] = 12 + 1
g[f(2)] = 13
The value of g[f(2)] = 13
