Answer:
Step-by-step explanation:
Fig 1
<f=180-2×30=180-60=120
<D and <E are base angle of isosceles triangle.
Fig 2
AB=AC=BC=8
All the side of equilateral are equal and all interior angle also equal.
Answer:
Step-by-step explanation:
a) ΔFED is isosceles triangle. EF = ED
∠F = ∠D =x {Angles opposite to equal sides are equal}
∠F + ∠E + ∠D = 180 {Angle sum property }
x +x + 30 = 180
2x + 30 = 180
2x = 180 -30
2x = 150
x = 150/2
x = 75
∠F = 75
b) All the angles are equal. So, it is an equilateral triangle. In equilateral triangle all sides are equal.
So, AB = 8

In a two-digit number, the tens' digit is 1 less than the units' digit. If the digits are
interchanged, the sum of the number obtained and the original number is 143. Find
the number.
Answers
Answer:
67
Step-by-step explanation:
Number: AB
A = B-1
BA + AB = 143
10*B + A + 10*A + B = 143
11A + 11B = 143
A + B = 13
(B-1) + B = 13
2B = 14
B = 7
A = 6
The number is 67
check: 6 = 7-1 and 67 + 76 = 143

Part A: Let y represent the number of rabbits after x years. Which functioncan be used to model y as a function of x, where x is a non negative number ?
А. y = 10 (3) ^ (x - 1)
В. y = 10 (3) ^ x
C. y = 3 (10) ^ (x - 1)
D . y = 3 (10) ^ x
Answers
Answer:
y = 10(3)x
Step-by-step explanation:
The exponential function that can represent the population of rabbits after [x] years is y = 10(3)ˣ.
What do you mean by domain and range of a function?For any function y = f(x), Domain is the set of all possible values of [x] for which [y] exists. Range is the set of all values of [y] that exists for the given domain.
Given is rate of increase of a rabbit's population.
The exponential function that can represent the population of rabbits after [x] years can be written as -
y = 10(3)ˣ
Refer to the graph attached.
Hence, the exponential function that can represent the population of rabbits after [x] years is y = 10(3)ˣ.

If the sum of the measures of the interior angles of a polygon is 1920°, how many sides does it have? math
Answers
Answer: There is no polygon with the sum of the measures of the interior angles of a polygon is 1920°.
Step-by-step explanation:
The sum of the measures of interior angles of a polygon with [tex]n[/tex] sides is given by:-
[tex](n-2)\times180^{\circ}[/tex]
Given: The sum of the measures of the interior angles of a polygon is 1920°.
i.e. [tex](n-2)\times180^{\circ}=1920^{\circ}[/tex]
[tex]n-2=\dfrac{1920}{180}\\\\ n= \dfrac{1920}{180}+2\\\\ n=\dfrac{2280}{180}=12.67[/tex]
But number of sides cannot be in decimal.
Hence, there is no polygon with the sum of the measures of the interior angles of a polygon is 1920°.
quadrilateral vwxy with vertices v(-2,-1) w(-5,-2) x(-8,-7) and y(1,-6): 18o from the origin
Answers
Given:
The vertices of a quadrilateral are v(-2,-1) w(-5,-2) x(-8,-7) and y(1,-6).
To find:
The vertices of the image of quadrilateral vwxy after 180° about the origin.
Solution:
If a figure rotated 180° about the origin, then the rule of rotation is
[tex](x,y)\to (-x,-y)[/tex]
Using this rule, we get
[tex]v(-2,-1)\to v'(2,1)[/tex]
[tex]w(-5,-2)\to w'(5,2)[/tex]
[tex]x(-8,-7)\to x'(8,7)[/tex]
[tex]y(1,-6)\to y'(-1,6)[/tex]
Therefore, the vertices of image of quadrilateral vwxy after 180° about the origin are v'(2,1), w'(5,2), x'(8,7), y'(-1,6).

Determinant of the coefficient matrix from online determinant calculator is;
D = 136
Determinant of the x-matrix from online determinant calculator is; Dx = 92
Determinant of the y-matrix from online determinant calculator is; Dy = 696
Determinant of the z-matrix from online determinant calculator is; Dz = 576
From crammers rule;
x = Dx/D = 92/136
y = Dy/D = 696/136
z = Dz/D = 576/136

Mike is catering a party. He plans on having 4 trays of 5 appetizers each on the buffet at the beginning of the party and will rotate in new trays as those become empty. To ensure that he does not run out of appetizers during the party, he is going to make 2 appetizers per person in addition to the initial number put out on the buffet. Which of the following represents A, the amount of appetizers Mike needs to make, in terms of p, the amount of people attending the party?
Answers
Answer:
A = 20 + 2p
Step-by-step explanation:
A = 4(5) + 2p
A = 20 + 2p
A = 2p + 20
A = 2(p + 10)
I’m getting the 20 from the 4 trays of 5 appetizers on the buffet. I’m getting the 2p from the “two appetizers per person”
