Answer:
a9=13122
Step-by-step explanation:an=a1rn−1
Substitute in the values of
a1=2 and r=3
an=(2)⋅(3)n−1
Remove parentheses.
an=2⋅3n−1
Substitute in the value of n to find the 9th term.
a9=2⋅3(9)−1
Subtract
1 from 9
a9=2⋅38
Raise 3 to the power of 8.
a9=2⋅6561
Multiply
2 by 6561.
a9=13122

Answer:
-2
Step-by-step explanation:
Hey there!!
if we evaluate the expression it will look like :
3x + 14 = 8
and if we solve it:
3x+14=8
Step 1: Subtract 14 from both sides.
3x+14−14=8−14
3x=−6
Step 2: Divide both sides by 3.
3x/3 = -6/3
x= −2
Pls pls help it's urgent. Due in another few minutes!!
which statement is true?
1. y=csc x and y=sec x intersect at y = 1.
2. the period of y =tan x is doubled the period of y=csc x.
3. the zeros of y= tan x and y= cos x are the same.
4. the local maximum points of y = sec x is the same as the absolute minimum points of y = sin x.
5. None of the above are true.
Answer:
5
Step-by-step explanation:
none of the above are true
1. intersect at x=45
so y=sqrt(2)
2. y=cscx period is doubled y=tanx
3. not the same
4. no local maximum of y=secx
minimum point of y=sinx is -1
so none of the above are true

A right triangle has one angle that measures 30°. What is the measure of the other acute
angle?
All angles must add up to 180º. We have 2 angles, they are 90º and 30º the last one can be found by the following equation:
[tex]x+30+90 = 180 \\~\\ x = 60[/tex]

is the sequence -2, 4, -6, 8 geometric, arithmetic or neither?
Answer: Neither
Notes: If a sequence does not have a common ratio or a common difference, it is neither an arithmetic nor a geometric sequence. You should still try to figure out the pattern and come up with a formula that describes it.
Which situation is best modeled with a division expression?
finding the number of equal-sized parts into which a number can be split.
finding the combined value of several cerent numbers.
finding the distance between two numbers on a number
line.
finding the total value when several of the same number are grouped together
Answer:
its finding the number of equal-sized parts into which a number can be split.

A. Lines 1 and 4 are parallel
B. Lines 2 and 3 are parallel
C. Lines 2 and 4 are perpendicular
D. Lines 1 and 2 are perpendicular
Answer:
Lines 2 and 4 are perpendicular
Step-by-step explanation:
Line 2: 4y=3x-4
y=3/4x - 1
Line 4: 4x+3y=-6
3y=-6-4x
y=-2 - 4/3x
The two lines are perpendicular since -4/3= - (inverse of 3/4)
Two lines 2 and 4 are perpendicular to each other. The correct option is C.
What is an equation of the line?An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.
The general form of the equation of the line:-
y = mx + c
m = slope
c = y-intercept
Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )
For two lines to be perpendicular the slope should be negative reciprocal. For two lines to be parallel the slope of the lines should be equal.
The equation of lines 2 and 4 is,
y = (3/4)x -1
y =(-4/3)x - 2
Here the slope of the two lines is reciprocal as well as negative.
Therefore, two lines 2 and 4 are perpendicular to each other. The correct option is C.

A ribbon on a spool is 10 yards long. How many 6-inch pieces of ribbon can be cut from the spool?
Answer:
60
Step-by-step explanation:
One yard is 36 inches.
So first you multiply 10 by 36 for 360.
Then you divide 360 by 6 and get 60.
So the answer is 60 pieces of ribbon.

A regular pentagon has a side of approximately 8.7 ft and an apothem of approximately 6.0 ft. Find the area of this pentagon.
Answer:
130.5 square inches bet you wont put me brainliest
Step-by-step explanation:
area of regular pentagon = (½)(apothem)(perimeter)
apothem = 6 inch
perimeter =5* 8.7 =43.5
area of regular pentagon = ½ * 6 * 43.5 = 130.5 square inches

Name two ways to find the missing sides of a composite figure?
Answer:
Step-by-step explanation:
length. To find the missing horizontal length, we will look at the values of the other horizontal lengths. Looking at the composite shape, the side that is 12 cm long is the same as both the missing side plus the side that is 4 cm long. We can therefore find the missing length by subtracting 6 cm from 9 cm.
