The first and thirteenth terms of an arithmetic sequence are 7/9 and 4/5, respectively. What is the seventh term?
Here,
Let the first term be denoted by a and commom difference by b.
Now,
T1 = a
= 7/9
T13 = a + 12 d
or, 4/5 = 7/9 + 12d
or 12d = 4/5 -7/9
or, 12d = 1/45
or, d = 1/410.
then,
T7= a + 6d
= 7/9 + 1/410
= 2879/2870

Is Amit's work correct? No, he should have used the origin as the center of the circle. No, the radius is 10 units, not 5 units. No, he did not calculate the distance correctly. Yes, the distance from the center to (2, –2) is not the same as the radius.
Answer:
C. No, he did not calculate the distance correctly.Step-by-step explanation:
The question is incomplete. Here is the complete question.
A circle centered at (–1, 2) has a diameter of 10 units. Amit wants to determine whether (2, –2) is also on the circle. His work is shown below. The radius is 5 units. Find the distance from the center to (2, –2). The point (2, –2) doesn’t lie on the circle because the calculated distance should be the same as the radius. Is Amit’s work correct? No, he should have used the origin as the center of the circle. No, the radius is 10 units, not 5 units. No, he did not calculate the distance correctly. Yes, the distance from the center to (2, –2) is not the same as the radius.
For Amit to determine whether the point (2, -2) is on the circle, we will need to find the distance between the coordinates (–1, 2) and (2, -2) using the formula:
D = √(y₂-y₁)² + (x₂-x₁)²
D = √(-2-2)² + (2-(-1))²
D = √(-4)² + (2+1)²
D = √16 + 9
D = √25
D = 5 units
Since the distance between the coordinate is equal to the radius of the circle, hence the coordinate (2, -2) lies on the circle.
Hence Amit is wrong because he did not calculate the distance correctly

Both ran at a constant speed.
Did they run at the same rate? Explain or show your reasoning.
I
They did not run at the same rate because
Answer:
They do not run at the same rate because Jada ran at a rate of .150km per min, while Andre ran at .133333 km per minute.
Step-by-step explanation:
Andre ran : 2km/15min = .133333km per min
Jada ran: 3km/20min=.150km per minute
.150>.1333, so Jada ran at a higher rate of kilometers per minute.

Step-by-step explanation:
i have 25cents Anyways I would say that the answer would be D it goes in order and 18:00 is greater then 3.25x + 1.50 so hope this helped
Answer:
D.) 3.25x + 1.50 ≤ 18.00
Step-by-step explanation:
She can spend up to $18, so she can spend $18 or less.
amount ≤ 18
Now we find an expression for the amount.
The total cost is (1) the cost of the shoe rental plus (2) the cost of each game.
(1) the shoe rental is a fixed $1.50
(2) the cost of the games depends on the number of games.
x is the number of games.
1 game costs $3.25.
2 games cost $3.25 * 2
3 games cost $3.25 * 3
x number of games cost 3.25x
The total cost is
1.50 + 3.25x which is the same as
3.25x + 1.50
The total cost must be less than or equal to 18.
Answer:
D.) 3.25x + 1.50 ≤ 18.00

Sports companies cover the surface of a soccer ball with waterproof spray to prevent it from getting water logged. The radius of a soccer ball is 11cm. The formula to calculate Surface Area of a ball is SA = 4πr2 S A = 4 π r 2 . How much surface do they need to cover with the spray?
Answer:
310.73cm^2Step-by-step explanation:
The expression for the total surface area is
SA=4πr^2
given that r=11cm
we want to substitute the value of r to solve for the area
SA=4πr^2
SA=4*3.142*(11)^2
SA=2.568*11^2
SA=2.568*121
SA=310.728
Therefore they need to cover a surface of 310.73cm^2

m less-than StartFraction 25 Over 3 EndFraction
m less-than StartFraction 49 Over 12 EndFraction
m greater-than StartFraction 49 Over 12 EndFraction
Answer: m> 49/12
Step-by-step explanation:
The graph is a parabola . The Parabola with minimum point. So, Substitute the minimum value in the equation. Thus the graph of have two x-intercepts when.
The graph is a parabola with the minimum where x= -b/2a = -7/6.
To have 2 x intercepts, the value at the minimum point must be less than 0, i.e.
3(49/36) - 49/6 + m < 0
49/12 - 49/6 + m < 0
(49-98)/12 + m < 0
-49/12 + m < 0
m < 49/12
The values of m < 49/12 the equation of the function y = 3x² + 7x + m have two x-intercepts option (C) m < 49/12 is correct.
What is a quadratic equation?Any equation of the form [tex]\rm ax^2+bx+c=0[/tex] where x is variable and a, b, and c are any real numbers where a ≠ 0 is called a quadratic equation.
As we know, the formula for the roots of the quadratic equation is given by:
[tex]\rm x = \dfrac{-b \pm\sqrt{b^2-4ac}}{2a}[/tex]
It is given that:
The equation of the graph:
y = 3x² + 7x + m
If the above quadratic function has two x-intercepts that means:
D > 0
b² - 4ac > 0
On comparing:
a = 3
b = 7
c = m
7² - 4(3)(m) > 0
49 - 12m > 0
12m < 49
m < 49/12
Or
m ∈ (-∞, 49/12) for which graph of a function have two x-intercepts
Thus, the values of m < 49/12 the equation of the function y = 3x² + 7x + m have two x-intercepts option (C) m < 49/12 is correct.

You are ordering shirts for the math club at your school. Short-sleeved shirts cost $10 each. Long-sleeved shirts cost $12 each. You have a budget of $300 for the shirts. The equation $10x+12y=300$ models the total cost, where $x$ is the number of short-sleeved shirts and $y$ is the number of long-sleeved shirts. a. Graph the equation. Interpret the intercepts
Answer:
a. i) Please see the included graph of the equation $10·x + $12·y = $300
ii) The intercepts give the maximum number of either short-sleeve (x-intercept) long-sleeved (y-intercept) that can be ordered
Step-by-step explanation:
The given information are;
The cost of each short-sleeved shirt = $10
The cost of each long-sleeved shirt = $12
The amount available in the budget = $300
The equation for the total cost = $10·x + $12·y = $300
Where;
x = The number of short-sleeved shirts
y = The number of long-sleeved shirts
Rewriting the equation given in slope and intercept form, we have;
$10·x + $12·y = $300
$12·y = $300 - $10·x
y = $300/$12 - $10·x/$12
y = 25 - 5/6·x
Please find attached, the graph of the equation made with Microsoft Excel
The values of the data that can calculated to plot the graph are;
x, y
(0, 25 )
(5, 20.83 )
(10, 16.67)
(15, 12.5 )
(20, 8.33)
(25, 4.17)
(30, 0 )
The x-intercept gives the number of short-sleeve shirts that can be purchased with the $300 available budget, while the y-intercept gives the number of short-sleeve shirts that can be purchased with the $300 available budget.
The graph of the equation is shown below.
The x-intercept is at point (30,0), which means the number of short-sleeved shirts is 30 when the number of long-sleeved shirts is 0.
The y-intercept is at point (0,25), which means the number of long-sleeved shirts is 25 when the number of short-sleeved shirts is 0.
Given:
Short-sleeved shirts cost $10 each.
Long-sleeved shirts cost $12 each.
The total budget is $300.
The given equation is:
[tex]10x+12y=300[/tex]
where [tex]x[/tex] is the number of short-sleeved shirts and [tex]y[/tex] is the number of long-sleeved shirts.
To find:
The graph of the given equation and the interpretation for the intercepts.
Explanation:
We have,
[tex]10x+12y=300[/tex]
Substitute [tex]x=0[/tex].
[tex]10(0)+12y=300[/tex]
[tex]12y=300[/tex]
[tex]y=\dfrac{300}{12}[/tex]
[tex]y=25[/tex]
So, the y-intercept is at point (0,25).
Substitute [tex]y=0[/tex].
[tex]10x+12(0)=300[/tex]
[tex]10x=300[/tex]
[tex]x=\dfrac{300}{10}[/tex]
[tex]x=30[/tex]
So, the x-intercept is at point (30,0).
Plot the points (30,0) and (0,25) on a coordinate plane and connect them by a straight line.
The x-intercept is at point (30,0), which means the number of short-sleeved shirts is 30 when the number of long-sleeved shirts is 0.
The y-intercept is at point (0,25), which means the number of long-sleeved shirts is 25 when the number of short-sleeved shirts is 0.
