Step-by-step explanation: What table? I would love to help you but I need to see the table you are talking about. :(

Answer:

No.

Step-by-step explanation:

53 + 35 = 88, add 18 = 106.

Answer:

no

Step-by-step explanation:

18x18 + 35 x35 = 53x53

324 + 1225 = 2809

1549 =\ 2809

Answer:

Step-by-step explanation:

Remark

Unless you know calculus, the only way to solve this is by completing the square.

Solution

y = 4x^2 + bx - 2

y = 4(x^2 + b/4 ) - 2

y = 4(x^2 + b/4 + (1/2b/4)^2 ) - 2 - 4*(b/8)^2

y = 4(x^2 + b/4 + (b/8)^2 ) -  2 - b^2/16

y = 4(x + b/8)^2 - 2 - b^2/16

Now what you want to happen is to give b/8 a value of 1 so that when x is put in -1 you get 0 for  what is inside the brackets.  

b/8 = 1

b = 8

y = 4(x + 1)^2 - 2 - (8)^2 / 16

y = 4(x + 2)^2 - 2 - 4

y = 4(x + 1)^2 - 6

The vertex is at (-1, - 6)

The axis of symmetry  is x = - 1

Note

This could have been done a lot shorter just by realizing that the number inside the brackets had to be + 1 as in (x + 1). But then you would not have been able to know the minimum value for y which is - 6

Answer:

Distance cover by Alyson = 16 miles

Step-by-step explanation:

Given:

Distance cover together = 39 miles

Assume;

Distance cover by Jeff = a

Distance cover by Alyson = a - 7

Find:

Distance cover by Alyson

Computation:

a + (a - 7) = 39

2a - 7 = 39

2a = 46

a = 23

Distance cover by Alyson = a - 7

Distance cover by Alyson = 23 - 7

Distance cover by Alyson = 16 miles

Answer:

3.08 hours

Step-by-step explanation:

Preparation for the homecoming football game, members of the student body are painting the spirit rock in front of the school.

If Angela works alone, it will take her five and a half hours.

If Brandon works alone, it will take him 7 hours. If they work together, it will take them approximately hours ?

This is calculated as:

The Number of hours they worked together = T

1/5.5 + 1/7 = 1/T

= 7 + 5.5/(5.5)(7)

= 12.5/38.5

1/T = 12.5/38.5

Cross Multiply

12.5T = 38.5

T = 38.5/12.5

T = 3.08 hours

The time required when Angela and Brandon work together, for the preparation for the homecoming football game, is 3.08 hours.

The total time taken is inversely proportional to the rate of work. If a unit of work is done in total n number of days, then the total work done in a day can is,

[tex]W_1=\dfrac{1}{n}[/tex]

In preparation for the homecoming football game, members of the student body are painting the spirit rock in front of the school.

If Angela works alone, it will take her five and a half hours. The work done by Angela in one hour is,

[tex]A=\dfrac{1}{5.5}\\A=\dfrac{2}{11}[/tex]

If Brandon works alone, it will take him 7 hours. The  work done by Brandon in one hour is,

[tex]B=\dfrac{1}{7}[/tex]

The work done in one hour, when the work together,

[tex]A+B=\dfrac{2}{11}+\dfrac{1}{7}\\A+B=\dfrac{14+11}{77}\\A+B=\dfrac{25}{77}\\A+B=\dfrac{1}{3.08}[/tex]

Thus, the time required when Angela and Brandon work together, for the preparation for the homecoming football game, is 3.08 hours.

Answer:

(6,2) y-coordinate is 2

Step-by-step explanation:

The coordinates of the point F on directed line segment AB that partitions AB in the ratio 3 :2 are: (6, 2)

The formula for finding the coordinates of a point that divides the line in ratio m:n are given by:

We are given that Point A (3,-4) and Point B (8,6) on directed line segment AB.

Here (x1,y1) and (x2,y2) are coordinates of the two points line passed through

(x1,y1) = A(-3,-4)

(x2,y2) = B(8,6)

Ratio: 3 : 2

m = 3

n = 2

Putting the values in the formula

( x, y) = (3 x 8 + 2 x 3 /5  , 3 x 6 + 2 x (-4) /5 )

( x, y) = (24 + 6 / 5 , 18 - 8 /5)

( x, y) = (30/5, 10/5)

( x, y) = (6, 2)

Hence,

The coordinates of the point F  are: (6, 2)

Answer:

  yes

Step-by-step explanation:

The side lengths of the triangle are 5, 12, and 5+8 = 13. We can check to see if they satisfy the Pythagorean theorem, which would indicate a right triangle.

  5² + 12² = 25 +144 = 169 = 13²

These sides do satisfy the relationship between sides for a right triangle, so angle A is a right angle. That is the case when segment AB is a tangent to the circle.

  Yes, AB is a tangent.

Answer:

336 ft²

Step-by-step explanation:

The figure is composed of a rectangle and a right triangle

A of rectangle = length × breadth = 24 × 12 = 288 ft²

A of Δ = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )

Here b = 32 - 24 = 8 ft and h = 12 , then

A of Δ = [tex]\frac{1}{2}[/tex] × 8 × 12 = 4 × 12 = 48 ft²

composite area = 288 + 48 = 336 ft²

$10.50

Step-by-step explanation:

Interest = future value - amount saved

The formula for calculating future value:

FV = P (1 + r)^n

FV = Future value  

P = Present value  

R = interest rate  

N = number of years

$50 x (1.1)^2 = $60.50

Interest = $60.50 - $50 = $10.50
