the nth term of a sequence is 3n²-1
what are the second and fifth terms?
2nd term: 3(2)^2 - 1
5th term: 3(5)^2 - 1
Answer:
11 and 74
Step-by-step explanation:
To find the second and fifth terms substitute n = 2, n = 5 into the rule, that is
a₂ = 3(2)² - 1 = 3(4) - 1 = 12 - 1 = 11
a₅ = 3(5)² - 1 = 3(25) - 1 = 75 - 1 = 74
What is the slope of the equation y = 3x + 2?
Answer:
3
Step-by-step explanation:
the equation is y=mx+b
m=slope
so then 3 would be the slope
hope this helps :3
if it did pls mark brainliest
Answer:
3
Step-by-step explanation:
To find the slope, think of the equation used for slope intercept form.
y = mx + b
m is the slope, and b is the y intercept.
In this equation, m = 3
Thus, the slope is 3

Determine if the table shows a linear or an exponential function
Answer:
The table shows an exponential function
Step-by-step explanation:
Linear vs Exponential Functions
A linear function is written as:
[tex]y=mx+b[/tex]
where m and b are constants.
If a table contains a linear function, then for each pair of ordered pairs (x1,y1) and (x2,y2), the value of m must be constant.
The slope can be calculated as:
[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]
An exponential function is written as:
[tex]y=y_o.r^x[/tex]
Where r is the ratio and yo is a constant.
If a table contains an exponential function, for two ordered pairs (x1,y1) and (x2,y2), the value of r must be constant.
The ratio can be calculated as:
[tex]\displaystyle r=\sqrt[x2-x1]{\frac{y2}{y1}}[/tex]
Calculate the slope for (0,4) and (1,2):
[tex]\displaystyle m=\frac{2-4}{1-0}=-2[/tex]
Calculate the slope for (1,2) and (2,1):
[tex]\displaystyle m=\frac{1-2}{2-1}=-1[/tex]
Since the slope is not the same, the function is not linear.
Now calculate the ratio for (0,4) and (1,2)
[tex]\displaystyle r=\sqrt[1-0]{\frac{1}{2}}[/tex]
The radical of index 1 is simply equal to its argument:
[tex]\displaystyle r=\frac{1}{2}[/tex]
Now calculate the ratio for (0,4) and (2,1)
[tex]\displaystyle r=\sqrt[2-0]{\frac{1}{4}}[/tex]
[tex]\displaystyle r=\sqrt{\frac{1}{4}}[/tex]
[tex]\displaystyle r=\frac{1}{2}[/tex]
Testing other points we'll find the same ratio, thus the table is an exponential function

Answer:
c
Step-by-step explanation:
It is given that the line AB is Perpendicular Bisector of IK. It means the line AB is perpendicular on IK and the point J divides the line IK in two equal parts.
If a line is bisector of another line, then the point of intersection divides the second line is two equal parts.
Therefore the distance between intersection point and the endpoints of the second line are the same.
The intersection point is J and the end points of IK are I and K. So, we can say that IJ = JK.

find the measurement for angle A
Answer: that is a 45 degree angle
Step-by-step explanation: 90 / 2 is 45
Answer:
∠ A = 44°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the 3 angles and equate to 180, that is
x + 59 + x + 51 + 84 = 180, simplify
2x + 194 = 180 ( subtract 194 from both sides )
2x = - 14 ( divide both sides by 2 )
x = - 7
Thus
∠ A = x + 51 = - 7 + 51 = 44°
Solve for x: x2 = 16
Answer:
8
Step-by-step explanation:
to get x alone you divide the 2 away on both sides, getting x = 8. To check multiply 8 by 2 and you get 16.
Hope this helps!
Take the root of both sides and solve.
x = 4, −4

Find the rate of change from the given table.
each marble bag sold by Lisas marbles company contains three red marbles for every four orange marbles if a bag has 24 red marbles how many orange marbles does it contain
Answer:
32 orange marbles.
Step-by-step explanation:
First set up the proportion given in the problem, since it states that there are three red marbles for every four orange marbles. The ratio between them is 3:4.
This means that you can multiply the given amount of red marbles by 4/3 to find the amount of orange marbles and the given amount of orange marbles by 3/4 to find the amount of red marbles. Because there are 3 red marbles for every 4 orange marbles.
You can divide 32 by 3 to find the factor which is 8 and multiply by 4 to get 32. Because 8 × 3 = 24,
and 8 × 4 = 32.
It can also be thought of as fractions because the proportion is a factor which means that you can multiply and divide to get to a certain value.
So:
3/4 = 24/O
Red marbles / orange marbles = red marbles / orange marbles.
(cross multiply ; numerator times denominator, and denominator times numerator; numerator is the top number, and the denominator is bottom number of a fraction).
3O = 96
÷3 ÷3
O [orange marbles] = 32

solve 2x-y > 1 for y
Answer:
y<2x−1
Step-by-step explanation:
1 Subtract 2x2x from both sides.
-y>1-2x−y>1−2x
2 Multiply both sides by -1−1.
y<-1+2xy<−1+2x
3 Regroup terms.
y<2x-1y<2x−1

Identify the intercepts of the line. 3x+2y=12
Answer:
The x-intercept is ( 4 , 0 ) .
The y-intercept is ( 0, 6 ) .
Step-by-step explanation:
his is the formula for a linear equation in standard form. This is the easiest equation for finding the intercepts. To find the x- and y-intercepts, substitute 0 for one variable, and solve for the other.
X-intercept: value of x when y = 0
Substitute 0 for y and solve for x .
3 x + 2 ( 0 ) = 12
3 x = 12
Divide both sides by 3 .
x = 12 /3
x = 4
The x-intercept is ( 4, 0 ) .
Y-intercept: value of y when x= 0
Substitute 0 for x and solve for y .
( 0 ) + 2 y = 12
2 y= 12
Divide both sides by 2 .
y = 12 /2
y = 6
The y-intercept is ( 0 , 6 ) .
These are the intercepts.
A jet plane can carry up to 200,000 liters of fuel. It used 130,000 liters of fuel during a flight. What percentage of the fuel capacity did it use on this flight? Do not include the percent sign (%) in your answer.
Given:
Capacity of jet plane = 200,000 liters of fuel
Fuel used during flight = 130,000 liters
To find:
The percentage of the fuel capacity it uses on this flight.
Solution:
According to the question, we need to find 130,000 is what percent of 200,000.
[tex]\text{Required percentage}=\dfrac{\text{Fuel used during flight}}{\text{Capacity of jet plane}}\times 100[/tex]
[tex]\text{Required percentage}=\dfrac{130000}{200000}\times 100[/tex]
[tex]\text{Required percentage}=65[/tex]
Therefore, the jet plane uses 65 percent of fuel capacity during flight.
