What is the measure of ∠BCE, in degrees, in the figure shown?
Answer:
25 degrees
Step-by-step explanation:
So a triangles angels equal 180 degrees
So for angel ECD 180 - (15+90) = 75
Straight lines also always equal to 180 degrees so
180 - (80+75) = 25
Measure of ∠BCE = 25° .
What is angle?A figure which is formed by two rays or lines that shares a common endpoint is called an angle. The word “angle” is derived from the Latin word “angulus”, which means “corner”.
Given, In figure,
∠CED = 15°
∠EDC = 90°
∠BCA = 80°.
In triangle ECD
Sum of all interior angles of a triangle is 180°
∠ECD +∠CED +∠EDC = 180°
∠ECD + 15° + 90° = 180°
∠ECD = 180° - 105°
∠ECD = 75°
Now,
∠BCA,∠BCE and∠ECD are at point C on line AD.
Sum of all angles made at one point of line is 180°.
∠BCA +∠BCE +∠ECD = 180°
80° + ∠BCE + 75° = 180°
∠BCE = 180° - 155°
∠BCE = 25°
Hence, 25° is measure of ∠BCE.

Suppose f(x) = x2 and g(x) = Which statement best compares the graph of g(x) with the graph of f(x)?
Answer:
g(x) is horizontally stretched by a factor of 1/5
Step-by-step explanation:
Given
[tex]f(x) = x^2[/tex]
[tex]g(x) = (\frac{x}{5})^2[/tex]
Require
Determine the relationship between f(x) and g(x)
[tex]f(x) = x^2[/tex]
[tex]g(x) = (\frac{x}{5})^2[/tex]
Express g(x) in terms of f(x)
[tex]g(x)=f(\frac{x}{5})[/tex]
This can further be simplified as:
[tex]g(x)=f(\frac{1}{5}x)[/tex]
When a function is represented as:
[tex]g(x) = f(cx)[/tex]
Where c < 1,
Then the type of translation is a horizontal stretch (stretch in the x direction)
By comparison: [tex]g(x) = f(cx)[/tex] and [tex]g(x)=f(\frac{1}{5}x)[/tex]
[tex]c = \frac{1}{5}[/tex]
This means that: g(x) is horizontally stretched by a factor of 1/5

which figure is a translation of Figure A? explain. A translation, or slide, is a transformation that moves every point of a figure the same distance & the same direction.
Answer:
Figure B
Step-by-step explanation:
A translation does not "flip" the position of the pre-image. Figure C is a reflection of figure A.
A translation would "slide" the figure into a new position without mirroring nor rotating it.
Figure B should be the translation of Figure A.
Hope this helps.
Figure B is the translation of figure A by 2 units up.
What is the transformation of the graph?If a graph is translated and rotates by any amount either in x and y direction then it will be transfomation of the graph.
For example transformation of graph f(x) by 2 units down.
The new resultant graph could be only translated or rotated or both.
Given figure A
If we look at C then the face of this is towards the right but in figure A the face is towards the left.
So it means C will translate + rotation of graph A it will not be pure translation.
In figure B it is clear that it is a translation of figure A by 2 units upward.
Hence "Figure B is the translation of figure A by 2 units up".

Answer:
The range of values of [tex](f + g)(x) \ge 3[/tex] is for all values of x [tex]-\infty[/tex] to [tex]+\infty[/tex]
Step-by-step explanation:
Given
[tex]f(x) = |x| + 9[/tex]
[tex]g(x) = -6[/tex]
Required
Describe the range of [tex](f+g)(x)[/tex]
First, calculate [tex](f+g)(x)[/tex]
[tex](f+g)(x) = f(x) + g(x)[/tex]
Substitute values for f(x) and g(x)
[tex](f+g)(x) = |x| + 9 -6[/tex]
Evaluate Like Terms
[tex](f+g)(x) = |x| + 3[/tex]
The above expression shows that [tex](f + g)(x) \ge 3[/tex]
Because [tex]|x| \ge 0[/tex]
Hence, the range of values of [tex](f + g)(x) \ge 3[/tex] is for all values of x [tex]-\infty[/tex] to [tex]+\infty[/tex]

I need help ok I need to find the length of ab
Inscribed angles
Please help!!!!!!!! With explanation!!!!!
Answer:
a = 72° b = 88°
Step-by-step explanation:
We know in the cyclic quadrilateral opposite angles are supplementary so
a + 108° = 180° { being opposite angles of cyclic quadrilateral }
a = 180° - 108°
a = 72°
b + 92° = 180° { being opposite angles of cyclic quadrilateral }
b = 180° - 92°
b = 88°

What is the equation of the line that passes through the point (5, – 7) and
has a slope of o?
Answer:
The answer is
[tex]y = - 7[/tex]
Answer:
y = -7
Step-by-step explanation:
Hey :)
y = mx + b
*m is equal to the slope...
y = (0)x + b
Plug in the point you have...
-7 = (0) (5) + b
-7 = 0 + b
-7 = b
y = (0)x - 7
y = -7
Ignore the (0)x because anything multiplied by 0 is 0 so there's no point in having 0x in your equation.
Answer: y = -7

Oliver expects that the number of visitors to a museum(y) is related to the daily rainfall in mm(x). He plots a scatter plot and determines the equation for the line of best fit: y=14.1x+62.0 What is the expected number of visitors when the daily rainfall is 20 mm? Give your answer to the nearest integer.
Answer:
344 visitors
Step-by-step explanation:
Given that the relationship between the number of visitors to a museum(y) and the daily rainfall in mm(x) is defined as
y=14.1x+62.0
when the daily rainfall is 20 mm, the number of visitors
y = 14.1(20) + 62
= 282 + 62
= 344
It means that the expected number of visitors is 344 persons (to the nearest integer).
