12. Write the first five terms of two different sequences that have 10 as the
second term. Describe the pattern in each of your sequences.
Answer:
a) The arithmetic sequence with common difference 2 that has 8 as the first term.
b) The arithmetic sequence of common difference -5 and first term 15.
Step-by-step explanation:
Let's use for example the arithmetic sequence with common difference 2 that has 8 as the first term. Then the first two terms of this sequence are:
8, and (8+2) = 10 Therefore the second term is 10.
Another arithmetic sequence of common difference -5 and first term 15. The firs two terms of this sequence are:
15, and (15 - 5) = 10. Therefore again a 10 as second term.
What is the area of the parallelogram?

Vector a = 4i + 5j
Vector b = 3i + 6j
Find the dot product.
Step-by-step explanation:
a · b = (4)(3) + (5)(6)
a · b = 12 + 30
a · b = 42
Answer:
42
Step-by-step explanation:
a*b = 4*3 + 5*6 = 12 + 30 ( where i*i = j*j = 1)
∴ a*b = 42
Find the 7th term in the
sequence
-1, -3, -9,...
Answer:
The answer is 729
Step-by-step explanation:
to get the next term, the sequence multiples the previous number by -3
1 * -3 = -3
-3 * -3 = 9
and so on.
To get the 7th term:
-27 * -3 = 81 (5th term)
81 * -3 = -243 (6th)
-243 * -3 = 729 (7th)
Answer:
The seventh term in the sequence is -729.
Step-by-step explanation:
Notice that the sequence is not increasing linearly. Therefore, this is a geometric sequence.
Recall that the explicit formula for a geometric sequence is given by:
[tex]x_n=a(r)^{n-1}[/tex]
Where a is the first term, r is the common ratio, and n denotes the nth term.
From the sequence, we can see that our first term a is -1.
Because each term is thrice the previous, our common ratio r is 3.
By substitution:
[tex]x_n=-(3)^{n-1}[/tex]
Hence, the seventh term is:
[tex]\displaystyle \begin{aligned} x_7 & = -(3)^{(7)-1} \\ \\ & = -(3)^{6} \\ \\ & = -729\end{aligned}[/tex]
In conclusion, the seventh term is -729.
What's the perimeter of triangle ABC
Answer:
[tex]\Large \boxed{12.9}[/tex]
Step-by-step explanation:

The perimeter of the triangle is 12.9.
Answer:
12.9 is the perimeter
Step-by-step explanation:
BC is 2 since B’C’ is equal to BC.

Find the equation of the line perpendicular to y=2x-6 that passes through the point (1,5). If possible, write the equation in slope-intercept form.
Answer:
y = - [tex]\frac{1}{2}[/tex] x + [tex]\frac{11}{2}[/tex]
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 2x - 6 ← is in slope- intercept form
with slope m = 2
Given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{2}[/tex] , thus
y = - [tex]\frac{1}{2}[/tex] x + c ← is the partial equation
To find c substitute (1, 5) into the partial equation
5 = - [tex]\frac{1}{2}[/tex] + c ⇒ c = 5 + [tex]\frac{1}{2}[/tex] = [tex]\frac{11}{2}[/tex]
y = - [tex]\frac{1}{2}[/tex] x + [tex]\frac{11}{2}[/tex] ← equation of perpendicular line

imagine you and a friend are trying to rearrange the furniture in your classroom. You push on a desk with a force of 150 N to the right. Your friend pushes on the same desk with a force of 50 N to the left. What is the net force on the desk?
Answer:
100NStep-by-step explanation:
If I push on a desk with a force of 150 N to the right and my friend pushes on the same desk with a force of 50 N to the left, this means that I pushed the desk in the positive x direction and the force I applied is F1 = +150N; my friend pushes the desk in the negative x direction and the applied force will be F2 = -50N.
THe net force will the sum total of both forces acting on the desk.
Net force F = F1+F2
Given F1 = +150N and F2 = -50N
Net force F = +150N+(-50N)
Net force F = +150N-50N
Net force F = +100N
Hence the net force on the desk is 100N
How to calculate the value of i=?
Answer:
0.200
Step-by-step explanation:
∑ₓ₌₁⁴⁰ (1 + i)⁻ˣ = 5
∑ₓ₌₁⁴⁰ ((1 + i)⁻¹)ˣ = 5
This is a geometric series. The sum of the first n terms of a geometric series is:
S = a₁ (1 − rⁿ) / (1 − r)
where a₁ is the first term and r is the common ratio.
Here, a₁ = (1 + i)⁻¹, r = (1 + i)⁻¹, and n = 40. For simplicity, let's write both a₁ and r in terms of r. So a₁ = r and r = r.
5 = r (1 − r⁴⁰) / (1 − r)
5 (1 − r) = r (1 − r⁴⁰)
5 − 5r = r − r⁴¹
r⁴¹ − 6r + 5 = 0
Solving with a calculator, r ≈ 0.8334.
Therefore:
(1 + i)⁻¹ = 0.8334
1 + i = 1.200
i = 0.200
Solve the following equations
(a) tydt + (t + 1)dy = 0,
(b) y dy dt + t = 1,
(c) ty0 + y = y 2 , with the initial condition, y(1) = 1 2
Answer:
A) In y = - [ x-In (x+1) ] + c
B) [tex]\frac{y^2}{2} = t - \frac{t^2}{2} + c[/tex]
Step-by-step explanation:
A) tydt + ( t + 1 ) dy = 0
dy/y = - ( [tex]\frac{tdt}{t+1}[/tex] ) we have to integrate both sides of the equation
In y = - [ x- In (x +1) ] + c
B) y dy/dt + t = 1
we can express the equation as :
y dy = ( 1 - t ) dt
when we integrate the equation we have
[tex]\frac{y^2}{2} = t - \frac{t^2}{2} + c[/tex]

10a -7 = 21 - ба
Answer:
A=1.75
Step-by-step explanation:
[tex]10a + 6a = 21 + 7 \\ 16a = 28 \\ divide \: both \: sides \: by \: 16 \\ a = 1.75 \: or 1 \ \frac{3}{4} [/tex]
Answer:
a = 7/4
Step-by-step explanation:
10a -7 = 21 - 6а
Add 6a to each side
10a+6a -7 = 21 - 6а+6a
16a -7 = 21
Add 7 to each side
16a+7-7=21+7
16a = 28
Divide each side by 16
16a/16 = 28/16
a = 7/4

my hw write find an equation of the line passing through (-2,3) and (4,-5) I have to write the equation in slope-intercept form I need help
Answer:
The line passing through the given points is:
[tex]y=-\frac{4}{3}x+\frac{1}{3}[/tex]
in its slope-intercept form
Step-by-step explanation:
Start by finding the slope of the segment that joins the two given points using the slope formula:
[tex]slope=\frac{y_2-y_1}{x_2-x_1}[/tex]
which for our case renders:
[tex]slope=\frac{3-(-5)}{-2-4}=\frac{8}{-6} =-\frac{4}{3}[/tex]
Now we can find the y-intercept by using any one of the given points in the general slope-intercept form of a line with this slope:
[tex]y=-\frac{4}{3} x+b\\3=-\frac{4}{3} (-2)+b\\3=\frac{8}{3}+b\\b=3-\frac{8}{3} \\b=\frac{9-8}{3} \\b=\frac{1}{3}[/tex]
Therefore, the equation of the line becomes:
[tex]y=-\frac{4}{3}x+\frac{1}{3}[/tex]
Find the missing variable and indicated angle measure. pls help lol
Answer:
see below (I hope this helps!)
Step-by-step explanation:
∠VZY and ∠VXW form a linear pair and are supplementary, and since m∠VZY = 90°, m∠VXW = 180 - 90 = 90°. Since m∠WXU + m∠UXV = ∠VXW, we can write the following equation:
44 + 5x - 4 = 90
5x + 40 = 90
5x = 50
x = 10°
Therefore, m∠UXV = 5 * 10 - 4 = 46°
Answer:
x = 10 m(UXV)=46°
Step-by-step explanation:
m(UXV) + m(UXW) = 90° because m(VXY)= 90°
m(UXW) = 44°
m(UXV) + 44° = 90°
m(UXV) = 46°
5x - 4 = 46°
5x = 50
5x/5 = 50/5
x = 10

Write the perimeter of the triangle as a simplified expression
Answer: 10y + 1
Step-by-step explanation:
The perimeter is the total distance round the figure.
Now, in this case it is going to be
Perimeter = 3y + 5 + 6y + y - 4
= 3y + 6y + y + 5 - 4
= 10y + 1
The perimeter of the given triangle is 10y + 1 units.
