Answer:
[tex]u_{n} = 2n^{2} -4n-3[/tex]
Step-by-step explanation:
a +b + c = - 5 First term in sequence
3a + b = 2 Difference between first two terms
2a = 4 Difference between the difference of the first two terms and the second third terms (the difference between -5 and -3 is 2 the difference between -3 and 3 is 6; the difference between 6 and two is 4)
2a = 4 so a = 2; 3(2) + b = 2 → 6 + b = 2 so b = -4; 2 - 4 + c = -5 → -2 + c = -5 so c = -3

which is the x-intercept for 4x-2y = 16? A) (4, 0) B (0, 4) C (0, 8) D (-8, 0)
Answer:
A.
Just plug in each point for the x and y and find which point is valid
Step-by-step explanation:
Answer:
(4,0)
Step-by-step explanation:
-2y= -4x + 16
y = 2x - 8
Plug 0 in for y
0 = 2x - 8
2x = 8
x = 4
find angle prq
please solve this
Answer:
∠ PRQ = 55°
Step-by-step explanation:
The angle subtended at the centre by an arc is twice the angle subtended at the circumference by the same arc, thus
∠ PQR = 0.5 × 110° = 55°

A city park has a large circular garden with a path around it. The diameter of the garden is 60 feet. Jason works for the City Park Department. He needs to spread plant food all over the garden. What is the area of the park he will cover with plant food?
Answer:
He will cover 2,827.433 feet² area of the park with plant food.
Step-by-step explanation:
The diameter of the garden is 60 feet and the radius will be 60 feet/2 = 30 feet.
diameter= 60 feet
radius = diameter/ 2= 60/2= 30 feet
The area of the circle can be found by the formula πr²
Area= πr²=π(30)²
Area = 900π= 2,827.433 feet²
He will cover 2,827.433 feet² area of the park with plant food.

Victor has a bag of dimes and quarters. He has a total of 36 coins worth $5.40.
Let x represent the number of dimes and y represent the number of quarters.
Which system of equations would be used to find out how many dimes and quarters Victor has?
{x+y= 5.4
0.1x +0.25y =36
{x=36−y
x+y=5.4
{y=x+36
x+y=5.4
{x+y=36
0.1x+0.25y=5.4
Answer:
{x+y=36
0.1x+0.25y=5.4
Step-by-step explanation:
just took the test sorry for being late
The system of equation that is used to find how many dimes and quarters Victor has is :
x + y = 36
0.1x + 0.25y = 5.40
x = number of dimes
y = number of quarters
Therefore,
Total number of coins will be
x + y = 361 dime = $0.1
1 quarters =$0.25
Therefore,
Total amount of dollars will be
0.1x + 0.25y = 5.40combine the equations:
x + y = 36
0.1x + 0.25y = 5.40
Therefore, the system of equation that is used to find how many dimes and quarters Victor has is as follows:
x + y = 36
0.1x + 0.25y = 5.40

Write the slope-intercept form of an equation for the line that passes through (2, 3) and is parallel to the graph of y = 2x -1
Answer:
ok
Step-by-step explanation:
Answer:
y = 2x -1
Step-by-step explanation:
when a two lines are parallel to each other that means they have the same slope.
you use point slope formula to find a line with the same slope and passes through (2,3)
y - y' = m(x - x') is the general form so you plug in (2,3) and the slope and you get
y - 3 = 2(x -2)
first your distribute the 2 into the parenthesis and you get
y-3 = 2x -4
now add 3 to both sides
y = 2x -1

Solving systems of equations using substitution/eliminationSolving systems of equations using graphingStep-by-step explanation:
Step 1: Define systems
3x + y = 2
4x + 3y = 3
Step 2: Rewrite systems
y = 2 - 3x
4x + 3y = 3
Step 3: Solve for x
Substitute in y: 4x + 3(2 - 3x) = 3Distribute 3: 4x + 6 - 9x = 3Combine like terms: -5x + 6 = 3Isolate x term: -5x = -3Isolate x: x = 3/5Step 4: Solve for y
Define original equation: 3x + y = 2Substitute in x: 3(3/5) + y = 2Multiply: 9/5 + y = 2Isolate y: y = 1/5Step 5: Check
Graph the systems of equations.
Answer:
x = 3/5, y = 1/5
Step-by-step explanation:
Starting with:
3x + y = 2
4x + 3y = 3
Multiplying the first equation by -3:
-9x - 3y = -6
4x + 3y = 3

Answer:
There is 2145.52 cubic inches of air in the ball
Step-by-step explanation:
A round ball is an example is hollow sphere. In order to find how much air the ball holds, the volume of the sphere needs to be found.
Given
Radius = r = 8 in
The volume of sphere is given by:
[tex]V = \frac{4}{3} \pi r^3[/tex]
Putting the values we get
[tex]V = \frac{4}{3} * \frac{22}{7} * (8)^3\\V = \frac{4}{3} * \frac{22}{7} * 512\\V = \frac{45056}{21}\\V = 2145.52\ in^3[/tex]

Which property should Remus use to solve the equation
below?
7q=49
Answer: It should be division property of equality.
Answer:
Division Property of Equality
Step-by-step explanation:
To solve this problem Remus needs to isolate the variable, which means to get rid of the 7. Since the 7 is being multiplied the opposite operation needs to be used; the opposite of multiplication is division. So each side needs to be divided by 7, the division property of equality tells us that an equation can be divided by anything as long as it is done on both sides. So to solve use the division property of equality to do 7q/7=49/7, which equals q=7 when simplified.
How many 2 3 -quart portions are in 7 1 2 quarts of soup?
Answer:
[tex]Number = 11\frac{1}{4}[/tex]
Step-by-step explanation:
Given
[tex]Soup = 7\frac{1}{2}[/tex] quarts
[tex]Portion = \frac{2}{3}[/tex] quarts
Required
Determine the number of portions in the soup
The question illustrates division of fractions and to solve this question, we simply divide the size of the soup by the size of the given portion
[tex]Number = Soup/Portion[/tex]
Substitute values for Soup and Portion
[tex]Number = 7\frac{1}{2}\ quarts /\frac{2}{3} \ quarts[/tex]
[tex]Number = 7\frac{1}{2}/\frac{2}{3}[/tex]
Convert mixed fraction to improper fraction
[tex]Number = \frac{15}{2}/\frac{2}{3}[/tex]
[tex]Number = \frac{15}{2} * \frac{3}{2}[/tex]
[tex]Number = \frac{15*3}{2*2}[/tex]
[tex]Number = \frac{45}{4}[/tex]
[tex]Number = 11\frac{1}{4}[/tex]
Hence, there are [tex]11\frac{1}{4}[/tex] of [tex]\frac{2}{3}[/tex] quarts in [tex]7\frac{1}{2}[/tex] quarts of soup
