Find the length of RS.
A. 40 units
B. 8 units
C. About 6.3 units
D. About 2.8 units
Given:
The two points on the graph are R(-2,-4) and S(-8,-6).
To find:
The length of RS.
Solution:
Distance formula: The distance between two points is
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Using the distance formula, the distance between R(-2,-4) and S(-8,-6) is
[tex]d=\sqrt{(-8-(-2))^2+(-6-(-4))^2}[/tex]
[tex]d=\sqrt{(-8+2)^2+(-6+4)^2}[/tex]
[tex]d=\sqrt{(-6)^2+(-2)^2}[/tex]
[tex]d=\sqrt{36+4}[/tex]
On further simplification, we get
[tex]d=\sqrt{40}[/tex]
[tex]d=6.32455532[/tex]
[tex]d\approx 6.3[/tex]
Therefore, the length of AB is about 6.3 units. So, the correct option is C.
If f(1) = 9 and f(n) = 4f(n − 1) then find the value of f(4).
Answer:
576
Step-by-step explanation:
f(2) = 4f(1) = 4*9 = 36
f(3) = 4f(2) = 4 * 36 = 144
f(3) = 4f(3) = 4 * 144 = 576
Use properties of operations to determine whether 4r + 4t and 4(r+t) are equivalent. Explain your answer.
There is only one property used to determine whether
[tex]4r+4t=4(r+t)[/tex].
The property is called the distributive property and in a nutshell it states, [tex]a(b+c)=ab+ac[/tex], which means [tex]a[/tex] is distributed through [tex]b+c[/tex] using multiplication. So [tex]4(r+t)[/tex] says, distribute [tex]4[/tex] to [tex]r[/tex] and [tex]t[/tex] which then translates into [tex]4r+4t[/tex].

Answer:
[tex]\frac{10}{11}[/tex]
Step-by-step explanation:
The formula for the trigonometric function sin is:
[tex]sin[/tex]Ф[tex]=\frac{opposite}{hypotenuse}[/tex]
The side opposite to the ∠g is x, which is equal to 10
[tex]opposite=x[/tex] [tex]x=10[/tex]
the hypotenuse of the triangle is z, which is equal to 11
[tex]hypotenuse=z[/tex] [tex]z=11[/tex]
so the ratio is:
[tex]\frac{10}{11}[/tex]
plz mark me brainliest. :)
Can someone explain how to solve and find x on the triangle
Step-by-step explanation:
sum of all the angles in a triangle is equal to 180°
82 + 70 + (2x + 4) = 180
152 + 2x + 4 = 180
156 + 2x = 180
2x = 180 - 156
2x = 24
x = 12
Hal earns $5 a week doing chores for his parents. He also earns $10 a week for each dog, d, he walks.
Write an equation to find m, the total amount of money Hal earns in one week. Which variable in the equation is the dependent variable and which variable is the independent variable? Tell how you know.
Answer:
Step-by-step explanation:
m = 5 + 10d
The variable "d" is the independent variable because its value does not depend on another variable. The variable "m" is the dependent variable because its value depends on the value of the variable "d"

Answer:
y=4x-5
Step-by-step explanation:
the slope intercept equation is y=mx+b
m=slope and b=y intercept
the slope is the change in y over the change in x and as y goes up 8 x goes over one 8/2=4 so the slope (m) is 4
The y intercept is at (0,-5) so b is -5
if we add it all together we get that the slope intercept equation is y=4x-5

4 is the value of log₃ 81.
We have,
A mathematical equation links two statements and utilises the equals sign (=) to indicate equality. In algebra, an equation is a mathematical assertion that proves the equality of two mathematical expressions. For instance, in the equation 3x + 5 = 14, the equal sign separates the numbers by a gap. A mathematical formula may be used to determine how the two sentences on either side of a letter relate to one another. The logo and the particular piece of software are usually identical. like, for instance, 2x - 4 = 2.
The equation may be changed to read:
x = log base 3 of 81.
81 being equivalent to 3 to the power of 4, we get the following:
x Equals log base 3 of 34.
We may reduce this to: Applying the rule that log base an of ab = b
4 = x
By answering the above question, we may infer that We may reduce this equation to: Applying the rule that log base an of ab = b, 4 = x.
Hence, x = 4.

Answer:
15.08 m
Step-by-step explanation:
You can take the appropriate fraction of the whole circumference, or you can use the arc-length formula. You get the same answer either way.
Angle XZW is 180° -108° = 72°
The circumference is C=πd, so the arc of interest is ...
XW = C(72°/360°) = πd/5 =π(24 m)/5 = 4.8π m
XW ≈ 15.08 m

Write and solve equations:
If asia is 10 years older than rani the sum of their age is 200
Let Asia's and Rani's age be "x"
Since Asia is 10 years bigger Asia will be "x+10"
Asia's Age + Rani's Age = 200
x + x + 10 = 200
2x + 10 = 200
2x = 200 - 10
2x = 190
x = 190
-----

x = 95
Asia = x + 10
95 + 10
105
Rani's age is 95 and Asia's Age is 105
While working on the roof of his house, John leans a 15 foot ladder against a second story window. If the distance on the ground between the base of the ladder and the house is nine feet, at what height does the ladder reach the second story window? In your final answer, include all necessary calculations.
Answer:
12 foot.
Step-by-step explanation:
Given that,
A ladder leans a 15 foot ladder against a second story window.
The distance on the ground between the base of the ladder and the house is 9 feet.
We need to find the height of the ladder. Let it is h.
If we consider a right angles triangle such that 15 foot is hypotenuse, 9 feet is base, then we need to find the perpendicular height of the triangle. Using Pythagoras theorem to find it.
So, the height of the ladder that reaches the second story window is 12 foot.

2/3x + 1/4 = 46/6x - 1/3
Answer:
x = 1/12
Step-by-step explanation:
2/3x + 1/4 = (8x+3) /12 (create equivalent fractions with a denominator of 12)
23/3x - 1/3 = (23x - 1) /3 *(46/6x = 23/3x)
8x + 3 = 23x - 1
12 3
now cross-multiply:
3(8x + 3) = 12(23x - 1)
24x + 9 = 273x - 12
9 = 252x - 12
21 = 252x
x = 21/252 which reduces to 1/12
Which of the following shows a translation of f(x) two units down?
A. f(x + 2)
B. f(x) + 2
C. f(x – 2)
D. f(x) – 2
Answer: D. f(x)-2
Step-by-step explanation:
Changes insides the parenthesis translate left and right. If it is [+] a number, then it is moving to the left. If it is [-] a number, then it is moving to the right.
Changes outside the parenthesis translate up and down. If it is [+] a number, then it is moving upward. If it is [-] a number, then it is moving downward.
----------------------------------------------------------------------------------------------------
Given
Translate f(x) 2 units downward
Solve
According to the rules, it should be -2 units outside of the parenthesis
Therefore, it should be f(x)-2
