Relationship: ________
Degree measure of angle 2: _______
Answers
Answer:
-The Relationship:
Both [tex]\angle 2[/tex] and the [tex]18\textdegree[/tex] angle are supplementary.
The measure of [tex]\angle 2[/tex]:
[tex]\angle 2 = 162\textdegree[/tex]
Step-by-step explanation:
-The relationship about both [tex]\angle 2[/tex] and the [tex]18\textdegree[/tex] angle, is that they are supplementary, which they both add up to [tex]180\textdegree[/tex].
-To find the measure of [tex]\angle 2[/tex], you need to subtract [tex]18[/tex] from [tex]180[/tex] to get the actual angle measurement of [tex]\angle 2[/tex]:
Finding the measure of [tex]\angle 2[/tex]:
[tex]180 - 18 = 162[/tex]
[tex]\angle 2 = 162\textdegree[/tex]
So, now you have the measure of [tex]\angle 2[/tex] .

A rectangular flower garden in Samantha’s backyard has 260 feet around its edge the with garden is 60 What is the length of the garden
Answers
Answer:
70 ft
Step-by-step explanation:
260 feet around its edge means perimeter
P = 2(l+w)
Width = 60
260 = 2( l+60)
Divide each side by 2
260/2 = 2/2(l+60)
130 = l+60
Subtract 60 from each side
130-60 = l+60-60
70 = l
The length is 70 ft

Which best explains whether or not triangles RST and ACB are congruent?
The figures are congruent. ΔRST can be mapped to ΔACB by a reflection over the x-axis and a translation 2 units to the left.
The figures are congruent. ΔRST can be mapped to ΔACB by a reflection over the y-axis and a translation 2 units down.
The figures are not congruent. Point R corresponds to point A, but S corresponds to B and T corresponds to C.
The figures are not congruent. Point R does not correspond with point A.
Answers
Answer:
Correct option: first one
Step-by-step explanation:
If we reflect the triangle RST over the x-axis, the y-coordinate of each point will have the sign switched, so the point S would be in (1, -5), the point R would be in (1, -1) and the point T would be in (4, -1)
Then, if we translate the resulting points 2 units to the left, we would have:
S = (-1, -5) -> matches point C
R = (-1, -1) -> matches point A
T = (2, -1) -> matches point B
So the triangles are congruent, and we can map from triangle RST to triangle ACB with a reflection over the x-axis and a translation of 2 units to the left.
Correct option: first one

What is the value of A and B and if you can please show how you got that answer
Answers
Answer:
a = 4.5 units
b = 7.5 units
Step-by-step explanation:
By using mean proportional theorem in the ΔACB,
ΔACB ~ ΔADC ~ ΔCDB
[tex]\frac{AD}{CD}=\frac{CD}{DB}[/tex]
[tex]\frac{8}{6}=\frac{6}{a}[/tex]
a = [tex]\frac{6\times 6}{8}[/tex]
a = 4.5
[tex]\frac{AB}{CB}=\frac{CB}{DB}[/tex]
[tex]\frac{(a+8)}{b}=\frac{b}{a}[/tex]
Since a = 4.5
[tex]\frac{4.5+8}{b}=\frac{b}{4.5}[/tex]
b² = 4.5 × 12.5
b = √56.25
b = 7.5 units
Therefore, a = 4.5 units and b = 7.5 units will be the answer.
y=x^{2} +2x-8 determine the axis of symmetry, the vertex point and find the roots by factoring
Answers
Answer:
x = -1 <--- axis of symmetry
(-1, -9) <-- vertex
2, -4 (or, in my old precalc class we wrote our roots as (2,0) and (-4,0)) <--- roots
Step-by-step explanation:
a) Axis of symmetry equation is defined as
[tex]-b/2a[/tex] = x (i memorized this)
Quadratic equation form:
[tex]ax^2+bx+c[/tex]
And our original equation:
[tex]x^2+2x-8[/tex]
So..
[tex]-2/2 = - 1[/tex]
So our axis of symmetry is at x = -1,
b) now vertex point can be found by plugging this value back into our original equation.
y = [tex](-1)^2+2(-1)-8[/tex]
y = 1 - 2 - 8
y = - 9
So our vertex is at (-1, -9)
c) Finally, lets factor
[tex]x^2+2x-8[/tex] = 0 (when finding the roots, set y = 0, because we are trying to find where we cross the x-axis)
[tex]x^2-2x+4x-8[/tex] = 0
[tex]x(x-2) + 4(x-2) = 0[/tex]
[tex](x-2)(x+4)=0[/tex]
x = 2; x = -4 <--- Roots

4) The population of the city in the year 2000 was 50000. The population is decreases by 0.95 each year
Step-by-step explanation:
a) Given an equation:
ax² + bx + c = 0
The equation would have imaginary solutions if b² - 4ac is negative. That is:
b² - 4ac < 0
Given an equation: 3x²+2kx+2=0
a) If k = -5
a= 3, b = 2k = 2 × -5 = -10, c= 2
b² - 4ac = (-10)² - 4(3)(2) = 76 > 0
It would not produce imaginary solutions
b) If k = -3
a= 3, b = 2k = 2 × -3 = -6, c= 2
b² - 4ac = (-6)² - 4(3)(2) = 12 > 0
It would not produce imaginary solutions
c) If k = -1
a= 3, b = 2k = 2 × -1 = -2, c= 2
b² - 4ac = (-1)² - 4(3)(2) = -23 < 0
It would produce imaginary solutions
d) If k = 2
a= 3, b = 2k = 2 × 2 = 4, c= 2
b² - 4ac = (4)² - 4(3)(2) = -8 <0
It would produce imaginary solutions
e) If k = 3
a= 3, b = 2k = 2 × 3 = 6, c= 2
b² - 4ac = (6)² - 4(3)(2) = 12 > 0
It would not produce imaginary solutions
f) If k = -5
a= 3, b = 2k = 2 × 4 = 8, c= 2
b² - 4ac = (8)² - 4(3)(2) = 40 > 0
It would not produce imaginary solutions
2)
A. Distribute 4 to the quantity ( x+1). to get:
1/2 x+12=8+4x+4
B. Add − 8 to each side of the equation. to get:
1/2 x+4=4( x+1)
C. Distribute 12 to the quantity ( x+1). This is not correct
D. Multiply each side of the equation by 2. to get:
x + 24 = 16 + 8(x +1)
F. Add together the 8 and the 4 on the right side of the equation. This is not correct
G. Multiply the left side of the equation by 2 to eliminate the fraction. This is not correct
3)
[tex]f(x)=x^2-2(r-s)x+(r-s)^2+(r+s)\\f(x)=x^2-2rx+2sx+r^2+s^2-2rs+r+s\\f(x)=x^2+r^2+s^2-2rs-2rx+2sx+r+s=(r-x-s)^2+(r+s)\\f(x)=(r-x-s)^2+(r+s)[/tex]
4) P( x )=50,000 ( 0.95 )^x, where x represents the number of years after the year 2000
At the year 2000, x = 0 therefore
[tex]P(x)=50000(0.95)^x=50000(0.95)^0=50000[/tex]
Since 0.95 is less than 1, it represent a population decay. 0.95 is the common ratio
The population is decreases by 0.95 each year

Hi!
So the first thing to do is to combine the common terms on each side.
On the left side, 13 and 2a cannot be put together because 2 has a multiplier that 13 does not.
On the right side, however, there are two numbers with the multiplier a. Add those together!
3a + 2a = 5a.
13 + 2a = 5a - 14
Now we want to isolate a to one side. Let's do the right side.
To do this, we have to subract 2a from both sides to get a on only one side.
13 + 2a - 2a = 5a - 2a - 14.
Subract.
13 = 3a - 14.
We have to do the same for the 14 on the right side. Instead, since the number is being subracted from 3a, we have to add it to both sides.
13 + 14 = 3a + 14 - 14.
27 = 3a
a = 9.

The Attached Table
Required
Calculate the relative frequency of the class with lower limit 27
Relative Frequency is calculated by dividing individual frequency by the total frequency
Mathematically,
[tex]Relative\ Frequency = \frac{Individual\ Frequency}{Total\ Frequency}[/tex]
The total frequency of the given data is 6+8+4+2+5+2
[tex]Total\ Frequency = 27[/tex]
The class with lower limit 27 has a frequency of 2;
Hence;
[tex]Relative\ Frequency = \frac{Individual\ Frequency}{Total\ Frequency}[/tex] becomes
[tex]Relative\ Frequency = \frac{2}{27}[/tex]
[tex]Relative\ Frequency = 0.07407407407[/tex]
[tex]Relative\ Frequency = 0.0741[/tex] (Approximated)
You may also leave your answer in percentage form
