In the diagram below, overline AE cong overline BE overline DE cong overline DC and m angle D=32^ . Find m angle A .
Answers
Step-by-step explanation:
since the triangle CDE is an isoceles triangle (the 2 legs DC and DE are equally), the 2 angles at its baseline CE are equal.
combined with the fact that the sum of all angles in a triangle is always 180 degrees we can therefore say :
180 = 32 + 2× base angle
148 = 2× base angle
base angle = 74 degrees.
the angle DEC is one of these base angles and therefore 74 degrees.
and because of the symmetry of angles of crossing lines, this is equal to the angle AEB.
the triangle AEB is also an isoceles triangle. the angle A is one of its base angles at the baseline AB.
so, the same principle as before :
180 = 74 + 2× base angle
106 = 2× base angle
base angle = 53 degrees.
so, angle A is 53 degrees.

⦿ Hi There! ⦿
Point-Slope form:
y-y1=m(x-x1)
y-1=m(x-(-6)
Perpendicular lines have slopes that are opposite reciprocals.
It means that if we have -1/2, we flop it over and make it positive.
So the slope of the new line is 2.
y-y1=m(x-x1)
y-1=2(x-(-6)
y-1=2(x+6)
y=1=2x+12
y=2x+12-1
y=2x+11

cubic polynomial
leading coefficient = 5
Step-by-step explanation:
The polynomial in standard form as 5x³-6x² -3x+2
and the polynomial is of degree 3 and the leading coefficient is 5.
What is Polynomial?An algebraic expression known as a polynomial requires that all of its exponents be whole numbers. Any polynomial must have variable exponents that are non-negative integers. Although a polynomial contains variables and constants, we are unable to divide a polynomial by a variable.
Example: The standard form of the polynomial 5 + 2x + x² is expressed.
We shall first determine the polynomial's degree before expressing it in standard form.
The degree of the provided polynomial is two. Write the phrase containing the polynomial's degree.
Given:
function is -3x+5x³-6x²+2
As, the polynomial contain coefficients and operations.
So, the given function is a polynomial.
Now, writing the polynomial in standard form as
f(x)=5x³-6x² -3x+2
The above polynomial is of degree 3 and the leading coefficient is 5.

Answers
Answer:
7
Step-by-step explanation:
To solve this problem, find the greatest common factor of the numbers representing the numbers of apples and pears respectively.
Each box will contain 3 pears and 4 apples.
And total number of fruits in each box will be 7 fruits.
It's given in the question,
Blake has 64 apples and 48 pears with him.
He has to put equal numbers of each fruit in a box.
To find the greatest number of fruits he can put in a box we will find the greatest common factor (GCF) of the given numbers first.
Therefore, greatest common factor of these numbers = =
GCF of these numbers tells about the number of boxes that can be prepared.
Now the number of pears that can be put in each box =
And the number of apples in each box =
Therefore, each box will contain 3 pears and 4 apples.
And total number of fruits in each box = 3 + 4 = 7 fruits.
is x to the second power plus y to the second power linear or non linear?

No, but the reason depends. Pick the one that applies to the question.
Are we talking function in two variables, ie [tex]z=f(x,y) = x^2+y^2[/tex] : in this case no, the surface you generate is a paraboloid - think the satellite dishes you use for telecomunications. not linear anyways.
Are we talking about [tex]x^2+y^2=0[/tex]? This has only one solution, which is the origin (0;0). in fact if you solve for either of the two you will get [tex]x^2=-y^2[/tex]. Now LHS is greater or equal than zero, RHS is lesser or equal than zero - the whole thing is true only if they are both 0. But still, not linear.
Are we talking about [tex]x^2+y^2 = r[/tex] with [tex]r>0[/tex] (since if it was we would be again at an absurd, something clearly non-negative is equal to a negative number)? Again, non linear, they are circles of radius [tex]\sqrt r[/tex] centered on the origin.

Answer:
f(x) = -x -1
Step-by-step explanation:
f(x) = mx + b
find 2 points on the line:
A( -1 , 0)
B( 0 , -1)
Put them in the equation and fine m & b:
0=m(-1)+b
-1=m(0)+b
so b= -1
and m= -1
so f(x) = -x-1
Answer:
-x - 1
Step-by-step explanation:
line is passing through (-1, 0) (0, -1)
m = (-1 - 0) / (0 - (-1) )
= -1 / 1
= -1
line equation = y - y1 = m (x - x1)
y - 0 = -1 (x - (-1) )
y = -1 (x + 1)
y = -x - 1
y = f(x)

Answers
Answer:
C. a= -1, m=1
Step-by-step explanation:
hope i helped, have a great day :)
For the function f(x) = [tex]\frac{2x^m}{ x + a}[/tex], if the horizontal asymptote is at y = 2 and vertical asymptote is at x = 1, then a = -1 and m = 1.
What are Asymptotes of a Function?There are asymptotes like horizontal, vertical and oblique asymptotes.
Horizontal asymptote is the value of the function f(x) as x goes to ±∞, as long as this value is not infinity.
Vertical asymptotes are the values of x which are not in the domain of the function f(x). For a fractional expression it is found by letting the denominator equals zero.
The given function is,
f(x) = [tex]\frac{2x^m}{ x + a}[/tex]
Horizontal asymptote of this function is at y = 2.
lim x → ∞ f(x) = 2
lim x → ∞ [tex]\frac{2x^m}{ x + a}[/tex] = 2
Eliminate 'a' in the denominator, because as x tends to infinity a + x also tends to infinity.
lim x → ∞ [tex]\frac{2x^m}{ x }[/tex] = 2
For the left hand side to become 2, [tex]x^m[/tex] in the numerator and x in the denominator should get cancelled.
⇒ [tex]x^m[/tex] = [tex]x[/tex]
⇒ m = 1
Vertical asymptote of the function is at x = 1.
Let x + a = 0
⇒ 1 + a = 0
⇒ a = -1
Hence we get the values a = -1 and m = 1 for the function f(x) = [tex]\frac{2x^m}{ x + a}[/tex] to have the horizontal asymptote at y = 2 and vertical asymptote at x = 1.

3 people can build 12 sheds in 4 days.In essence; By proportion 1 person can build 4sheds in four days.
We are required to determine how long it will take 5 people to build 15 sheds.
Therefore: for 1 person;
4 sheds ====4 days15 sheds ====15days.Therefore, it takes 1 person 15 days to build 15 sheds.
Ultimately, when the job is divided between 5 people; It takes 15/5 = 3 days to build 15 sheds.
