104 term in sequence -4,-1,2,5
ARITHMETIC SEQUENCE
an = a1 + (n-1)d
.
The formula above is used to get the nth term of an arithmetic sequence, but we can also use it to know the number of terms (n).
.
Given:
a1 = 4
d = a2 - a1 = 1 - 4 = -3
an = -29
n = ?
.
Solution:
an = a1 + (n-1)d
-29 = 4 + (n-1)-3
-29 = 4 + (-3n + 3)
-29 = -3n + 7
-29 - 7 = -3n
-36 = -3n
-36/-3 = -3n/-3
12 = n
.
Therefore, -29 is the 12th term of the arithmetic sequence 4, 1, -2, -5, ...
104(th) term in sequence -4, -1, 2, 5 would be 305.
What is function?A function is a relation between a dependent and independent variable.
Mathematically, we can write → y = f(x) = ax + b.
Given is to find 104(th) term in sequence -4, -1, 2, 5.
The sequence given is a arithmetic progression. We can write the function for nth term as -
a{n} = a + (n - 1)d
a{104) = - 4 + 103 x 3
a{104} = - 4 + 309
a{104} = 305
Therefore, 104(th) term in sequence -4, -1, 2, 5 would be 305.

What is 10,274 - 100,000
Answer:
_89,726
Step-by-step explanation:
This would be a negative answer in less you mean 100,000 - 10,274.
This would be negative because 10,000 per say can't subtract 100,000 in less it goes on the negative side.
But if you meant 100,0000-10,274 it is the same answer just with no nefative sign

Find the measures of the numbered angles in rhombus ABCD .
look for all four measures numbered in the photo
Answer:
<1=54, <2=36, <3=90, <4=36
Step-by-step explanation:
in the rhombus shown, there are 4 congruent right triangles because the disgonals of a rhombus are perpendicular and the sides of a rhombus are congruent. We already know that the larger acute angles are all 54 degrees and we can use triangle sum to find that the smaller acute angles are all 36 degrees. Obviously the right angles are 90 degrees, so we can look at the picture and find the marked angles.

A cylinder has a height of 11 meters and a volume of approximately 1243 cubic feet. What is the height of a cone with the same volume and radius as the cylinder?
Answer:
Step-by-step explanation:
Comment
There is a short cut to this and we might just as well use it. Start by writing the general formulas for the volume of a cylinder and the volume of the cone
Equation
V_cylinder = pi * r^2 * h
V_Cone = (1/3) pi * r^2 * h1
Solution
The volumes are equal, so the right sides must be equal as well
pi * r^2 * h = (1/3)*pi * r^2 * h1 Divide both sides by pi
r^2 * h = (1/3) * r^2 * h1 Divide both sides by r^2
h = (1/3) * h1 Multiply both sides by 3
3*h = h1 h = 11 (given)
3*11 = h1
33 = h1
Answer: the cone's height = 33 meters.
An altitude is drawn from the vertex of an isosceles triangle, forming a right angle and two congruent triangles. As a result, the altitude cuts the base into two equal segments. The length of the altitude is 25 inches, and the length of the base is 20 inches. Find the triangle’s perimeter. Round to the nearest tenth of an inch.
Check the picture below.
The perimeter of the given triangle is 73.8 inches.
What is the perimeter of a triangle?The perimeter of a triangle is defined as the addition of the lengths of the triangle's three sides.
The length of the altitude is 25 inches, and the length of the base is 20 inches.
Using the Pythagoras theorem, to find the hypotenuse of the triangle :
Hypotenus = √(25² + (20/2)²)
Hypotenus = √(625+ 100) = √725= 26.9 inches
The perimeter of a triangle :
(base + side 1 + side 2) = (20 + 26.9 + 26.9 ) = 73.8 inches
Therefore, the perimeter of the triangle is 73.8 inches.
