The nth term of an arithmetic sequence is expressed as Tn = a +(n - 1)d. The 157th term of the sequence is 2180
Arithmetic sequenceThe nth term of an arithmetic sequence is expressed as:
Tn = a +(n - 1)d
where
a is the first termd is the common differencen is the number of termsIf -4 is the first term and 10 is the third term, then;
a = -4
a + d = 10
d = 10 - (-4)
d = 14
Determine the 157th term
T157 = -4 + (157 - 1)(14)
T157 = -4 + (156*14)
T157 = 2180
Hence the 157th term of the sequence is 2180

The regular price of a pair of jeans is x dollars. Let f(x) = x - 15, where frepresents the price of
the jeans discounted by $15. Let g(x) = 0.8 x represent the price of the jeans discounted by 20%.
Use composition to find the price of the jeans if they are first discounted by 20%, then by $15.
Answer:
(f o g)(x) = 0.8x - 15
Step-by-step explanation:
(f o g)(x) = f(g(x)) = applying first g(x), and then using that result as input value for f(x).
so, first we discount by 20% and use g(x)
g(x) = 0.8x
and then we use that in f(x)
f(0.8x) = 0.8x - 15
and that is the result.

Consider the given function. Plot the x-intercept(s), y-intercept, vertex, and axis of symmetry of the function.
Answer:
Following are the solution to the gvien question:
Step-by-step explanation:
Let the quadratic equation is:
[tex]\to h(x) = (x + 1)^2 - 4[/tex]
vertex is:
[tex]\to h(x) = a(x -h)^2 + k[/tex]
(h) = axis of symmetry
(h,k) = vertex.
By using the given equation:
[tex]h(x) = (x - (-1))^2 - 4[/tex]
Hence,
[tex]h = -1 \\\\ k = -4[/tex]
line of symmetry [tex]x = -1[/tex]
vertex is [tex](h,k) = (-1,-4)[/tex]
finding the x intercept:
[tex](x + 1)^2 = 4\\\\\sqrt{(x + 1)^2} = \sqrt{4}\\\\x + 1 = \pm 2\\\\x = 2-1 \ \ \ \ \ \ \ \ \ \ or \ \ \ \ \ \ \ \ \ \ \ \ \ \ x =-2 -1\\\\x = 1 \ \ \ \ \ \ \ \ \ \ \ \ \ \ or \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ x =-3\\\\[/tex]
x -intercepts -3,1
Calculating the y-intercept when x = 0 putting into the real equation:
[tex]h(x) = (0 +1)^2 - 4 \\\\y = 1 - 4\\\\y = -3[/tex]

What's the area of it
Answer:
33.5 units²
Step-by-step explanation:
We can see this figure as 2 shapes: a square and a triangle. The square measures 4 x 4, and it's area is 16. That leaves the triangle, which has half the area of a quadrilateral that measures 5 x 7. The area of the quadrilateral is 35, and the triangle has an area of 17.5, which is half of that. Adding them together, we get 33.5.
Answer:
33.5 unit²
it's a mixture of triangle and square.
draw a imaginary straight line across the figure from that line which has length of 3 units and now you can see the triangle and the square. Use the formula to find area of triangle and area of square and the sum of their area will be the area of this whole figure i.e 35.5 unit²
what is f(x) = 3 × 8^x when x is equal to 3
Answer:
Answer is 1536
Step-by-step explanation:
plug in 3 for x
f(3) = 3*8^3 = 1536
Answer:
1536
Step-by-step explanation:
f(x) = 3 * 8 ^ x
x = 3
f(3) = 3 * 8 ^ 3
8^3 = 8 * 8 * 8
8^3 = 512
f(3) = 3 * 512
f(3) = 1536

What is the approximate value of tan C?
Answer:
B. 0.38
Step-by-step explanation:
Tan = Opposite/Adjacent
Opposite of angle C = 5 and adjacent = 13
Hence tan C = 5/13 = .38
Answer:
Step-by-step explanation:
Remark
You are given a right angle triangle, so it is possible to define the Tangent directly.
Definition
The tangent = opposite side / adjacent side.The opposite side (AB) is the side not connect to the angle's vertex (C)The adjacent side (BC) is the side that is connect to the angle's vertex (C). It is not the longest side in triangle. The hypotenuse (BC) is the longest side.Solution
Opposite Side = 5
Adjacent side = 13
Tan(C) = 5/13 = 0.3846

Someone help- I don't know how to solve this- maybe my teacher typed it in wrong? 2.4(m - 3) = 3.8 = -8.2
Answer:
m = 4.58
Step-by-step explanation:
Given equation :
2.4 ( m - 3) = 3.8
So now we open the brackets and multiply the terms.
⇒ 2.4 m - 7.2 = 3.8
⇒ 2.4 m = 3.8 + 7.2
⇒ 2.4 m = 11
⇒ m = [tex]\frac{11}{2.4}[/tex]
⇒ m = 4.58
Therefore, the correct value of the variable m by solving the equation is 4.58

What is the relationship between the angles that are formed by two intersecting lines?
Hi there!
Adjacent angles, or angles that are next to each other, add up to 180 degrees. They are supplementary.
Examples: 1 and 4, 3 and 4, 2 and 3, 1 and 1
Opposite angles, or angles that are opposite of each other, have the same measure.
Examples: 1 and 3, 2 and 4

Remmi wrote the equation of the line y = one-third (x + 2) He solved for x and got x = 3 y minus 2 Which of the following is an equivalent equation for x?
Answer:
x = 3y - 2
Step-by-step explanation:
Given the equation y = 1/3(x+2), we are to make x the subject of the formula;
y = 1/3(x+2)
Cross multiply
3y = x+2
Subtract 2 from both sides
3y - 2 = x+ 2 -2
3y - 2 = x
Swap
x = 3y - 2
This give the required equation

What Has a central point that stays fixed and everything else moves around that point in a circle- full rotation is 360 degrees.
Answer:
Rotary motion.
Step-by-step explanation:
Motion describes the movement of objects with respect to time.
When an object performs a circular or rotary motion, every point on the object moves around a central point in a continuous manner. Examples of objects that performs circular motion are: blades of an electric fan, rotation of the earth about its axis, the wheel of a moving bicycle etc.
From the cited examples, it would be observed that all points on the objects moves around a fixed central point.

Answer:
Step-by-step explanation:
There are three surfaces to add up to.
A1, the top surface of the cone (r=1,h=2)
A2, The curved surface of the cylinder (r=1 , h = 13-2 = 11)
A3, The circular base of the cylinder (r=1)
The slant height of the cone, s = sqrt(1^2+2^2), s = sqrt(5)
The length (circumference of the base), l = 2 pi r = 2pi r = 2pi
The area is
A1 pi s l = pi * sqrt(5) (2 pi r) = 2(pi^2)sqrt(5)
The curved surface has an area of
A2 = 2 pi r h = 2pi (1)(11) =22pi
The base has an area of
A3 = pi r^2 = pi
Total area = A1+A2+A3 = 2sqrt(5) (pi^2) + 22pi + pi
= 2sqrt(5) pi^2 + 23pi
= 116.4 m^2 approx.

Which equation of the line passes through the point (0,4) and is perpendicular to the lines whose equation is y=-1/2x + 3
Answer:
y = 2x+4
Perpendicular lines, when you multiply their gradient, you will get -1. You can also find the negative reciprocal, which is 2. The point (0,4) is the y intercept, which is for. Hence, the equation is y=2x+4

Step-by-step explanation:
Hey there!
Given function is f(X) = 11x+7.
Let f(X) be y.
So, y = 11x+7
Interchanging"X" and "y" we get;
X = 11y+7
or, X-7 = 11y
or, y = (x-7)/11
Therefore {f}^{ - 1} (x) = \frac{x - 7}{11} [/tex]

Function Q: y =1/3x + 2 Identify function Q as linear or nonlinear. State a reason why it is linear or nonlinear.
Answer:
A linear function is written in slope-intercept form as:
y = a*x + b
Where a is the slope and b is the y-intercept.
So any function of this shape, is a linear function, such that when graphed it is a straight line.
In this case, the function you wrote is:
Q: y = 1/3x + 2
Now, if the function is exactly what you wrote, then x is in the denominator:
y = 1/(3*x) + 2
Clearly, this is different than the general linear equation you can see above (here the variable is in the denominator) then in this case Q is non-linear.
If instead, the actual function Q is:
Q: y = (1/3)*x + 2
Then this is a linear equation, where the slope is 1/3 and the y-intercept is 2.
