is the sequence below is arithmetic {1, 8, 27,64}
Answer:
No
Step-by-step explanation:
No, because 8 - 1 ≠ 27 - 8. So, there is no common difference which is needed in order for the sequence to be arithmetic

Step-by-step explanation:
Find the slope of the line that passes through the points (0,-5) and (-2,-3).
Answer:
the slope is -1
Step-by-step explanation:
formula for slope is (y2-y1)/(x2-x1)
lets say (-2,-3) is (x2,y2)
-3-(-5)=2
-2-0=-2
2/-2=-1
can you please help me with this ASAP!!
firstly u can take the value of x=3 then put the value of x in equation..then u will get y = 0 so from this equation u get this(3,0)
then do same thing take value x = 6 and then u will get the value of y = -1 therefore u will get (6,-1)
Now plot these two points (3,0) and (6,-1) on graph..
Hope it helps u..!!
help me please!!! no links 10 points
in persectev i think the answer in bound to be 17/10
Answer:
x=3 y=13
Step-by-step explanation:
now you got x... substitute x value with one of the questions then you get y
-3×3+2y=17
-9+2y=17
2y=17+9
y=26/2
y=13
i hope it's clear this is how elimination method works... this is how i learned.... t☺️❤️

Use the reverse order of operation to solve this problem.
2m = 1
Answer: m = 1/2 or 0.5
Step-by-step explanation:
The order of operation within this problem is multiplication meaning we must divide instead.
2m = 1
2m/2 = 1/2
m = 1/2 or 0.5

Solve a ship leave port and travel 21km on a bearing of 032° and then 45km on a bearing 287 calculate the distance and bearing of the port from the ship
Answer:
Step-by-step explanation:
Let shall be considering the Cosine rule in this situation.
a^2 = b^2+c^2- 2bc.cosA
Where a = ?
b = 21km
c 45km
A = 131
a^2 = 21^2+45^2-2(21*45).cos131
a^2 = 441+2025-1890(-0.6560)
a^2 = 2466+1239.951
a^2 = 3705.951
a= 60.876km
Finding the bearing of the port from the ship.
We shall be considering the Sine rule
Sin A/a = Sin B/b
Where A = ?
a = 45km
B = 131°
b = 60.876km
Sin A/45 = sin131/60.876
SinA×60.876 = 45×sin131
SinA×60.876= 45×0.7547
SinA×60.876 = 33.961
SinA= 33.961/60.876
SinA = 0.5578
A = sin^-1 0.5578
A = 33.9°

Answer:
Z = 2
Step-by-step explanation:
This tape diagram is split into two equal parts.
Since 2 and 2 are equal, and since 2 and 2 have a sum of 4, then z is equal to 2.
Answer:
z = 2
Step-by-step explanation:
if two z go into 4 then it's 2 because 2 is the only number that goes into 4 twice
PLEASE HELP ASAP! WILL GIVE BRAINLIEST! The following three shapes are based only on squares, semicircles, and quarter circles. Find the perimeter and the area of each shaded part.
Answer:
Solution:- In the given figure
Side of square= 10 cm
area of square = side x side m= 10 x 10 = 100 sq cm
Now , diameter of semi circle AOD = 2r = 10cm
⇒ radius of semi circle AOD = 5 cm
∴ area of AOD =
similarly Area of semicircle BOC =
Area of white portion in figure 1 = area of square - [ area of semicircle BOD + area of semicircle AOD]
=
Total area of white portion in the given figure=
∴Area of Shaded portion = area of square - area of total white portion
=
So the area of shaded portion is
Now perimeter of AD(which is a semicircle) = (as perimeter of semicircle=πr)
So the perimeter of shaded region = 4×perimeter of AD=4×15.7=62.8cm

I think it is 457.333333 π m3
Hope this helped :T
Answer:
1436.76
Step-by-step explanation.
[tex]\frac{4}{3}\pi r^{3}[/tex]
that is the formula, with r being the radius.
then if you replace r with 7 that would be the answer.
pi, also equals 3.14159265359, or shortened 3.14.
so it would look like:
[tex]\frac{4}{3}*3.14*7^{3}[/tex]
