Step-by-step explanation:
Determine whether each given pair of endpoints lies on the same horizontal or vertical line.
If so, find the length of the line segment that joins the pair of points.
If not, explain how you know the points are not on the same horizontal or vertical line.
(3,-8) and (3,-1)
Given:
The pair of end points: (3,-8) and (3,-1).
To find:
Whether the given pair of endpoints lies on the same horizontal or vertical line.
Solution:
If the x-coordinates of pair of endpoints are same, then the pair of endpoints lies on the same vertical.
If the y-coordinates of pair of endpoints are same, then the pair of endpoints lies on the same horizontal.
The given endpoints are (3,-8) and (3,-1).
From the given endpoints, it is clear that the x-coordinates of the endpoints are same. So, the given endpoints lies on the same vertical line.
The length of the line segment that joins the pair of points is
[tex]D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
[tex]D=\sqrt{(3-3)^2+(-1-(-8))^2}[/tex]
[tex]D=\sqrt{(0)^2+(-1+8)^2}[/tex]
[tex]D=\sqrt{(7)^2}[/tex]
[tex]D=7[/tex]
Therefore, the given endpoints lies on the same vertical line and the length of the line segment is 7 units.

Someone help and please make sure it’s right
Answer:
20°
Step-by-step explanation:
Look at the attached photo.
∠a and ∠e are equal because they are vertical angles.
So, m∠a = 110°
Then, ∠f is an exterior angle to angles a and c. So,
m∠f = m∠a + m∠c
Substitute and solve.
130 = 110 + m∠c
m∠c = 20°
Then, ∠c and ∠d are vertical angles so they are equal.
m∠c = m∠d
m∠d = 20°
I hope this helps! Feel free to ask any questions!

To build a garden bed, James bought 36 feet of wood. If he makes the length of the garden 10 feet, what will the width be?

36 - 20 = 16
16 / 2 = 8
Answer is 8
16-2t=5t+9?????????????????????????????????????
Answer:
t=1
Step-by-step explanation:
16-2t=5t+9 (add 2t)
16=7t + 9 (subtract 9)
7=7t (divide 7)
t=1
Answer:
t=1
Step-by-step explanation:
step one : rearrange terms
16−2=5+9
−2+16=5+9
step two: subtract 16 from both sides of the equation
−2+16=5+9
−2+16−16=5+9−16
step three: simplify
−2=5−7
step four:Subtract 5t from both sides of the equation
−2=5−7
−2−5=5−7−5
step five: combine like terms
−7=−7
step six: divide
−7 /−7 =−7/−7
A man has a certain unknown sum of money, 60% of that sum Is 4800 rupees. What is the sum of money?
Answer:
8000
Step-by-step explanation:
I did a simple way, I divided 4800 by 3 and got 1600, then multiplied 1600 by 5. Because 2x5 =10 (or 100%)
Answer:
x = 8000
Step-by-step explanation:
here's your solution
=> it is given that 60% of some unknown
number is 4800
=> now, let the unknown number be X
=> so, 60/100*X = 4800
=> X = 4800*100/60
=> X = 8000
Find the explicit rule: 2, 6, 18, 54, 162
Answer:
f(n) = 2 × [tex]3^{n-1}[/tex]
Step-by-step explanation:
In order to write an explicit rule for a geometric function, you need to know the common ratio; you can find the common ratio by dividing two consecutive terms:
6 ÷ 2 = 3, 18 ÷ 6 = 3, 54 ÷ 18 = 3, etc..
Now you know the common ratio is 3. At this point you can write your explicit function following the rule f(n) = [1st term] × [common ratio]^(n-1):
f(n) = 2 × 3^(n-1)

Step-by-step explanation:
A sample of a radioactive isotope had an initial mass of 360 mg in the year 1998 and
decays exponentially over time. A measurement in the year 2004 found that the
sample's mass had decayed to 270 mg. What would be the expected mass of the
sample in the year 2011, to the nearest whole number?
Answer:
193 mg
Step-by-step explanation:
Exponential decay formula:
[tex]A_t = A_0e^r^t[/tex]where Aₜ = mass at time t, A₀ = mass at time 0, r = decay constant (rate), t = timeOur known variables are:
1998 to the year 2004 is a total of t = 6 years.The sample of radioactive isotope has an initial mass of A₀ = 360 mg at time 0 and a mass of Aₜ = 270 mg at time t.Let's solve for the decay constant of this sample.
[tex]270=360e^-^r^(^6^)[/tex][tex]270=360e^-^6^r[/tex] [tex]\frac{3}{4} =e^-^6^r[/tex][tex]\text{ln} (\frac{3}{4} )= \text{ln}(e^-^6^r)[/tex] [tex]\text{ln} (\frac{3}{4} )=-6r[/tex] [tex]r=-\frac{\text{ln}\frac{3}{4} }{6}[/tex] [tex]r=0.04794701[/tex]Using our new variables, we can now solve for Aₜ at t = 7 years, since we go from 2004 to 2011.
Our new initial mass is A₀ = 270 mg. We solved for the decay constant, r = 0.04794701.
[tex]A_t=270e^-^(^0^.^0^4^7^9^4^8^0^1^)^(^7^)[/tex] [tex]A_t=270e^-^0^.^3^3^5^6^2^9^0^7[/tex][tex]A_t=193.01982213[/tex]The expected mass of the sample in the year 2011 would be 193 mg.

A scooter costs $160. A bicycle costs 20% more than the scooter. How much does the bicycle cost? ?
Answer:
$192
Step-by-step explanation:
160 = 100% or 1.00
20% = 0.2 + 1.00
= 1.20
160 x 1.20 = $192
Answer:
$192
Step-by-step explanation:
$160 + 20% = $192
In the figure below, MN | KL and are intersected by transversals ML and KN M 1551 What is the measure of , XMN?
130°
85°
55°
50°
Answer:
∠ XMN = 50°
Step-by-step explanation:
∠ XNM and ∠ XKL are alternate angles and are congruent, then
∠ XNM = 35°
The sum of the 3 angles in a triangle = 180° , so
∠ XMN = 180° - (95 + 35)° = 180° - 130° = 50°
Geometry Angle of elevation/depression
Answer:
m∠ACB = 49.88°
Step-by-step explanation:
From the figure attached,
Measure of wire AC attached to the top 'C' of the building BC = 340 m
Horizontal distance between the base 'B' of the building and point A = 260 m
Angle of depression = ∠ACB
By applying sine rule in the given triangle,
sin(∠ACB) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]
= [tex]\frac{AB}{BC}[/tex]
= [tex]\frac{260}{340}[/tex]
m∠ACB = [tex]\text{sin}^{-1}(764706)[/tex]
= 49.88°

how to write the radical √8 using rational exponents?
Answer:
2√2
Step-by-step explanation:
√8 can be simplified to √(4)(2) , since 4 x 2 still equals 8. But now, 4 is a perfect sqaure, and whenever we get a perfect sqaure, we divided it by its root and put that number on the outside.
For ex: √32 = √(16)(2), since 16 x 2 = 32. 16 is a perfect sqaure, so we take its root and put it on the outside 4√2 ,
Now with this one, we'll do the same thing: √(4)(2) = 2√2

x+(y+1) divided by 5
Answer:
uhm so you'd assume y is more than 5 so maybe try x +(7+1) /5
now do x + 8 /5. x must be like 7 so
x= 7 and y= 7 so it is 7 + (7+1) divided by 5 which is 3 I believe
simplifying it just as is is more like x + (y+1) / 5

Answer:
≈ 15 ft
Step-by-step explanation:
There is a right triangle formed by the ground, the building and the ladder.
The ground and the height the ladder is up the wall are the legs and the ladder is the hypotenuse.
let x be the distance from the base of the building to the bottom of the ladder.
Using Pythagoras' identity in the right triangle
x² + 26² = 30²
x² + 676 = 900 ( subtract 676 from both sides )
x² = 224 ( take the square root of both sides )
x = [tex]\sqrt{224}[/tex] ≈ 15 ft ( to the nearest foot )
