Find the 100th term to 1,3,9,27
Answer:
The n-th term of this sequence appears to be
3
n
−
1
,
n

1
.
Step-by-step explanation:
These are powers of
3
ordered from
3
0
=
1
to
3
a
(for an integer
a
≥
1
). However, the first convenient value for
n
is
1
, not
0
(imagine saying the 0th term of a sequence). Because of that, since the first term is actually
3
0
, we need to start from the first term (
n
=

) being
3

The lengths of the legs of a right triangle are 8 yards and 15 yards. What is the length, in yards, of the third side of the triangle?
A.23
B.17
C. 12.7
D.11.5
Answer:
B
Step-by-step explanation:
By inspection it can' be C or D since they are shorter than the 15 yard side.
Also B is just slightly big than 15, so it is mostly likely incorrect
I would guess A is the answer, proven to be INCORRECT see below
the correct answer is B. 17 yards
check the answer using the pythagorean theorem
a² + b² = c²
a = 8
b = 15
c = √(64 + 225)
= √289
= 17 my guess was wrong!!!!
One angle of an isosceles triangle measures 32°. Which other angles could be in that isosceles
triangle?
Answer:
32° and 116°
Step-by-step explanation:
An isosceles triangle has two equal angles and the other angle is found by subtracting the sum of the two equivalent angles from 180°.
Since, one of the angles are given in the problem, one of the angles is 32°.
To find the other angle, we subtract the two angles from 180°.
180° - 32° - 32°
116°
The other two angles are: 32° and 116°

ОВ. 1(5 + 3x)
Ос. 3(5 + х)
OD. 5(3x)
оооо
Answer:
A. 5(1 + 3x)
Step-by-step explanation:
5(1 + 3x)
(5 × 1) + (5 × 3x)
5 + (5 × 3x)
5 + 15x
A works. Let's check the rest.
1(5 + 3x)
(1 × 5) + (1 × 3x)
5 + (1 × 3x)
5 + 3x
B does not work.
3(5 + х)
(3 × 5) + (3 × x)
15 + (3 × x)
15 + 3x
C doesn't work.

A student solved the equation sin2x/cosx=2, 0(greater than or equal)x(greater than or equal)pi, and found an answer of pi/2. Describe the student's error.
Please show all steps.
Answer:
The student forgot about the double angle identity.
Step-by-step explanation:
sin2x/cosx=2
This is the double angle identity
sin2x=2sin(x)cos(x)
(2sinxcosx)/cosx=2
2sinx=2
sinx=1
x=sin^-1(1)
x=90 degrees OR pi/4

Given the definitions of f(x) and g(x) below, find the value of g(f(-1)).
f(x) = 3x² + 5x – 7
g(x) = 2x + 13
Answer:
-5
Step-by-step explanation:
At first,
f(-1) = 3 x (-1)² + 5 x (-1) -7
= 3 - 5 - 7
= -9
g(f(-1)) = g(-9)
= 2 x (-9) + 13
= -18 + 13
= -5

identify the domain and range of the relation
{(4, 2), (1, 3), (0, 0), (-1, -1), (1, -3)
Answer:
So, the domain are:
[tex]x = 4,1,0,-1[/tex]
The range are:
[tex]y = 2,3,0,-1,-3[/tex]
Step-by-step explanation:
Given:
[tex]\{(4, 2), (1, 3), (0, 0), (-1, -1), (1, -3)\}[/tex]
Required
The domain and the range
In relation, we have:
[tex]\{(x_1, y_1), (x_2, y_2), ......, (x_n, y_n)\}[/tex]
Where the x values are the domain and the y values represent the range.
So, the domain are:
[tex]x = 4,1,0,-1[/tex]
The range are:
[tex]y = 2,3,0,-1,-3[/tex]

I need help on finding the height of a triangular pyramid
if there’s no work, I don’t get credit
I will give Brainliest
Answer:
20 in
Step-by-step explanation:
The formula for the volume of a triangular pyramid is V=1/3 x B x H, in which B is the area of the base and H is the height. You're given the volume and area of the base so you can just plug that into the formula. You will get 120 = 1/3 x 18 x H. You can multiply the 1/3 and 18 so you will get 120 = 6H. In this case, you are solving for H so you need to isolate the variable. You can do this by dividing both sides by 6. You will end up eith 20 = H.
