Find the general term of the quadratic sequence 3, 6, 11, 18, 27,....,...​

Answer:

T = 35 + 5s

Step-by-step explanation:

Here, we want to write an equation for the the total amount that has been saved.

Let the number of weeks he has saved for be s

Then his total savings will be 5 * s = 5s

Now let’s add the $35 from his parents

This will give 35 + 5s

let T be the total

amount that hass beeem saved

So;

T = 35 + 5s

where a represents the number of weeks for which he has saved and T represent the total money that has been saved

Answer:

translated  1 unit right and 2 units up followed by a reflection across x axis

Step-by-step explanation:

Parallelogram has vertices A(−2, 1), B(−4,−3), C(2,−5), D(4,−1) while parallelogram A'B'C'D' has vertices A'(-1, -3) B'(-3, 1) C'(3, 3) D'(5, -1)

Transformation is the movement of a point from its initial location to  new location. If an object is transformed then all its points are transformed. Types of transformation are rotation, reflection, dilation and translation.

If a point X(x, y) is translated a units right and b unit up , the new point is X'(x + a, y + b).

If a point X(x, y) is reflected across the x axis, the new point is X'(x, -y)

If parallelogram ABCD is translated  1 unit right and 2 units up (i.e. x + 1, y + 2), the new points is A*(-1, 3), B*(-3, -1), C*(3, -3), D*(5, -1). If a reflection across x axis is then done, the new point is A'(-1, -3) B'(-3, 1) C'(3, 3) D'(5, -1)

Answer:

A translation 1 unit right and 2 units up followed by a reflection across the x-axis.

Answer:

x = 6

Step-by-step explanation:

Given a tangent and a secant from an external point to the circle, then

The square of the tangent is equal to the product of the measures of the external part and the entire secant, that is

x² = 4(4 + 5) = 4 × 9 = 36 ( take the square root of both sides )

x = [tex]\sqrt{36}[/tex] = 6

Answer:

42.85% or 6/14

Step-by-step explanation:

6 / 14 = 0.428571428571

0.428571428571 * 100 ~ 42.85%

Work Shown:

N = weight of Noah's dog = 15 & 1/3 pounds

A = weight of Aiden's dog = unknown

A = 3*N

A = 3*(15 & 1/3)

A = 3*(15 + 1/3)

A = 3*15 + 3*(1/3) .... distribute

A = 45 + 1

A = 46

Aiden's dog weighs 46 pounds.

Answer:

x=1 1/4 (1.25), y=1/4

Step-by-step explanation:

Since the equation "y=x-1" seems simple enough, we're going to plug that in for our other equation, "-4x+3=-2".

1. Rearrange y=x-1 to fit our other equation, -4x+3=-2.

y=x-1 (add 1 to both sides)

y+1=x x=y+1

2. Plug our newly rearranged equation into -4x+3=-2.

-4(y+1)+3=-2

-4y-4+3=-2 (distributive property)

3. Add/subtract like terms.

-4y-1=-2

4. Get y to be by itself.

-4y=-1 (add 1 to both sides)

y=1/4

1. Now for y=x-1. Plug 1/4 into y.

1/4=x-1

1 1/4=x

-8 1/2

Step-by-step explanation:

-8 1/3 + (- 1/6)

Get a common denominator

-8 2/6 - 1/6

Combine terms

-8 3/6

-8 1/2

Answer:

4/5

Step-by-step explanation:

y2-y1/x2-x1 so....... 5-1/3-(-2)

You plug it into the equation for calculating slope:

(Y₂ - Y₁) ÷ (X₂ - X₁)

Let X₂ be 3 and Y₂ be 5.

X₁ = -2 and Y₁ = 1.

(5 - 1) ÷ (3 - (-2))

4 ÷ 5

4/5

The slope is 4/5.

Answer:

-4

Step-by-step explanation:

To find the slope, you can use the formula y2-y1/x2-x1. Plugin any set of values. Say 13 is y2, and 5 is y1. 13-5=8. We now have 8/x2-x1. You have to use the x-values of the y-values that you already used. -2 is x2 and 0 is x1. -2-0=-2. 8/-2 = -4.

Answer:

Hi There! There are no solutions to this system.

Step-by-step explanation:

nd When graphing a set of equations, make sure that the slopes are not equivlient. If the slopes are equivlient, the lines are parallel, and parallel lines do not intersect. You can check the slope of the equations to find if they are equal. Both graphs go down by 3 each time they go over 2, making the slope -3/2. If they have the same slope, but a diffrent Y interset, they are parallel.   You can also set the equations equal to  each other, and when solving find that 7 does not equal 1, or

-3/2X+7=-3/2X+1

+3/2X

7=1

Because this is false, the lines will not intersect.

Answer:

$101.97

Step-by-step explanation:

Diameter of circular wooden deck = 30 ft

Radius of the deck = ½ of diameter = ½*30 = 15 ft

Area of deck = πr² = 3.14*15² = 706.5 ft²

1 gallon covers 250 ft² (1 gallon = 250 ft²)

Let x be the number of gallons that will cover 706.5 ft² of the deck

Thus:

1 gallon = 250 ft²

x = 706.5 ft²

Cross multiply

1*706.5 = 250*x

706.5/250 = x

2.826 = x

Number of gallons to cover the deck is approximately 3 gallons (approximated to nearest whole number). Since the we can't buy a gallon that is not full, we approximate to give us 3 gallons.

1 gallon cost $33.99 (1 gallon = $33.99)

3 gallons cost: 3*33.99 = $101.97

Answer:

yes

Step-by-step explanation:

the diagnols are congruent meaning that the diagnol lines in the middle are the same length. So theoretically the left and right lengths are the same, and the top and bottom lengths are the same. The triagles named both have the same base and they're hieght is sbviouysly the same so they would be SSS each of the sides on one triangle coresspondes to the other.

Answer: Inequality that describes the number of people P that she can invite if Janelle has No more than $95 dollars to spend on the party bags: 7P  ≤  95  

Step-by-step explanation:

Given: The cost of the party bag is $7 per person.

P represents the number of people that she can invite.

Total cost for P people = ( cost per person) x (P)

=$ 7P   (i)

If  Janelle has No more than $95 dollars to spend on the party bags.

That means , Total cost ≤ $ 95

From (i)

7P  ≤  95   , which is the required inequality.

Answer:

it's 3xy^5 + 5x^2 -2x +6

Answer:

y-intercept: (0, -2)

x-intercept: (4, 0)

Step-by-step explanation:

The x intercept occurs when y = 0, so you can substitute 0 in for y and solve for x as shown:

-4x+8y=-16

-4x+8(0)=-16

-4x+0=-16

-4x=-16

x=4 ---------- format correctly in (x, y) : (4, 0)

The y intercept occurs when x = 0, so you can substitute 0 in for x and solve for y as shown:

-4x+8y=-16

-4(0)+8y=-16

0+8y=-16

8y=-16

y=-2 ---------- format correctly in (x, y) : (0, -2)
