Answer:
[tex]A(n) = -4n -10[/tex]
Step-by-step explanation:
Given
[tex]Sequence:\ -10, -14, -18, -22[/tex]
Required
Determine the formula for the nth term
The sequence shows arithmetic progression.
So, we need to determine the common difference (d) first
[tex]d = A_2 - A_1[/tex]
In this case:
[tex]A_2 = 2nd\ Term = -14[/tex]
[tex]A_1 = 1st\ Term = -10[/tex]
So:
[tex]d = -14 - (-10)[/tex]
[tex]d = -14 + 10[/tex]
[tex]d = -4[/tex]
The nth term is then calculated as thus:
[tex]A(n) = A_1 + (n - 1)d[/tex]
[tex]A(n) = -14 + (n - 1)* -4[/tex]
[tex]A(n) = -14 -4n + 4[/tex]
[tex]A(n) = -4n + 4-14[/tex]
[tex]A(n) = -4n -10[/tex]

Answer:
D: The slope is 3
Step-by-step explanation:
To figure out the slope, which is always a constant, you simply figure out the average displacement using the points we already know. This is described by the equation y2-y1/x2-x1. Let's use the ordered pairs (-3, 2) and (-1, 8) to figure this out.
8-2/-1-(-3) = 6/2 = 3
Another method you could use is to graph the points and figure out how many units y has to go up for every x over, or the "rise over run"
Either way, your slope is 3.
Answer:
its 3

−2c + 6 = −8
Solve for c, please
Answer: c=13/2 but as a fraction
Step-by-step explanation:
Answer:
c = 7
Step-by-step explanation:
-2c + 6 = -8
Subtract 6 from both sides
-2c = -14
Divide -2 by both sides
c = 7
Need help on this question ASAP
Answer:
284 mm^2
Step-by-step explanation:
We observe that the figure is made up of 2 squares and 1 triangle.
Lets consider the bigger square.
We observe that it sides are 12 mm
Hence, its area would be the square of its sides and hence, 144 mm^2.
Lets now consider the smaller square.
We observe that it sides are 7 mm
Hence, its area would be the square of its sides and hence, 49 mm^2.
Now,
Lets take the triangle into consideration.
We observe that,
One of its segments is not given to us and needs to be computed;
Lets take the length of this segment as x
Hence,
As the one of the sides of both the squares sum up to the lengths of the segment and 8,
[tex]12+7=x+8\\12+7-8=x\\x=11[/tex]
We now find its:
Base = 3+11 =14 mm
Height = 13mm
Hence, its area would be :
[tex]\frac{bh}{2} \\=\frac{14*13}{2} \\=7*13\\=91 mm^2[/tex]
Hence,
The Sum of the total figure = Sum of Areas of both the squares and that of the triangle
Hence,
The Sum of the total figure =
[tex]91+144+49\\= 284 mm^2[/tex]
please can someone solve

A) Quadratic variation. This is because the equation is in the form y = kx^2 with k = 1/8.
B) Inverse variation. Recall that inverse variation is in the form y = k/x which we can solve to xy = k. Here we have k = 9.
C) Direct linear variation. This equation is in the form y = kx, which is also known a direct proportional relationship because k = y/x. In this case, k = 1/11.

Hannah made a ramp for her grandfather who was in a wheelchair. The ramp was 10 ft long and it was 5 ft away from the porch steps. How high were the porch steps?
Given :
Length of ramp( Hypotenuse ), l = 10 ft .
Length of base, b = 5 ft .
To Find :
How high were the porch steps.
Solution :
Let, height is h.
By Pythagoras theorem :
[tex]b^2+h^2=l^2\\\\h=\sqrt{l^2-b^2}\\\\h=\sqrt{10^2-5^2}\\\\h = \sqrt{75}\\\\h = 5\sqrt{3}\ ft[/tex]
Hence, this is the required solution.
