what is four billion squared with the constant of 44

Answer:

  a = -2/9

Step-by-step explanation:

Locate two points that cross grid intersections and compute the slope of the line between them. I would choose the vertex (4, 4) and the point (-5, 2) as being points where the graph crosses grid intersections.

The slope of the line between those points is given by the slope formula ...

  m = (y2 -y1)/(x2 -x1)

  m = (2 -4)/(-5 -4) = -2/-9 = 2/9

We note that this representation of the absolute value function appears inverted (reflected across the x-axis). That means the coefficient 'a' will be negative. The slope of an unmodified absolute value function is -1 to the left of the vertex. It will only be 2/9 if the function has been multiplied by -2/9.

  a = -2/9

Additional comment

The vertex on the graph is at (4, 4), so the values of (h, k) are (4, 4).

Answer:

[tex]-\frac{2}{9}[/tex]

Step-by-step explanation:

Using the points (-5,2) and (4,4), the slope is given as 2/9. This is an absolute value graph, so from this information the slope is either 2/9 or -2/9. The graph faces downwards, so the slope is negative and therefore [tex]-\frac{2}{9}[/tex].

Answer:

Step-by-step explanation:

You want the values of x and PS for the trapezoid in the figure, given that its perimeter is 228 units.

The trapezoid is shown as an isosceles trapezoid, so PS = RQ. The Triangle RTQ will be repeated on the left side, meaning there is a point T' below point S such that T'P = 4 and T'T = SR = 4x+1.

The perimeter is the sum of side lengths. Working clockwise from the upper left corner this is ...

  perimeter = (4x+1) +(2x -3) +4 +(4x +1) +4 +(2x -3) = 12x +4

Solving for x, we find ...

  12x +4 = 228

  12x = 224

  x = 224/12

  x = 18 2/3

And PS is ...

  PS = RQ = 2x -3 = 2(18 2/3) -3 = 37 1/3 -3

  PS = 34 1/3

Answer:

x = 12 and y = -9

                                            Explanation:

Given:

2 x +3y = -3

3x + 5y = -9

make x the subject:

[tex]2 x +3y = -3[/tex]

[tex]2x = -3 - 3y[/tex]

[tex]x = \frac{-3 - 3y}{2}[/tex] _____equation 1

[tex]3x + 5y = -9[/tex]

[tex]3x = -9-5y[/tex]

[tex]x = \frac{-9-5y}{3}[/tex] ______equation 2

solve them simultaneously:

[tex]\frac{-9-5y}{3} = \frac{-3 - 3y}{2}[/tex]

[tex]2(-9-5y) = 3(-3-3y)[/tex]

[tex]-18-10y = -9 - 9y[/tex]

[tex]-10y + 9y = -9 + 18[/tex]

[tex]-y = 9[/tex]

[tex]y = -9[/tex]

now solve for x:

[tex]2 x +3y = -3[/tex]

[tex]2x + 3(-9) = -3[/tex]

[tex]2x -27 = -3[/tex]

[tex]2x = -3 + 27[/tex]

[tex]2x = 24[/tex]

[tex]x = 12[/tex]

coordinates where they both intersect is (12,-9) at one point so they have one solution

Answer:

x = 12

y = -9

The system has one solution as it has one point of intersection at (12, -9)

Step-by-step explanation:

Equation 1:   [tex]2x + 3y = -3[/tex]

Equation 2:   [tex]3x + 5y = -9[/tex]

Rewrite equation 1 to make [tex]x[/tex] the subject:

       [tex]2x + 3y = -3[/tex]

[tex]\implies 2x = -3 - 3y[/tex]

[tex]\implies x = -\dfrac32 - \dfrac32 y[/tex]

Substitute this into equation 2 and solve for [tex]y[/tex]:

       [tex]3( -\dfrac32 - \dfrac32 y)+5y=-9[/tex]

[tex]\implies -\dfrac92 - \dfrac92 y+5y=-9[/tex]

[tex]\implies -\dfrac92 +\dfrac12 y=-9[/tex]

[tex]\implies \dfrac12 y=-\dfrac92[/tex]

[tex]\implies y=-9[/tex]

Substitute y = -9 into one of the equations to find [tex]x[/tex]:

      [tex]2x + 3(-9) = -3[/tex]

[tex]\implies 2x - 27 = -3[/tex]

[tex]\implies 2x = 24[/tex]

[tex]\implies x=12[/tex]

The residual value when the value of x = 4 is -1, the correct option is B.

Given

Melissa collected the data in the table.

The difference between the observed value of the dependent variable (y) and the predicted value (ŷ) is called the residual.

The value of x= 4 then the value of residual is given by;

[tex]\rm Residual=Given - predicted \ value[/tex]

Here, given is 9 and the predicted value is 10 for x =4.

Substitute all the values in the formula;

[tex]\rm Residual=Given - predicted \ value\\\\\rm Residual=9-10\\\\\rm Residual=-1[/tex]

Hence, the residual value when the value of x = 4 is -1.

180°

sum of angles of triangle = 180°

Answer:

∠A + ∠B + ∠C = 180⁰

Step-by-step explanation:

The sum of the angles in a triangle is 180. This sum is a semicircle or a straight angle. The angle of the semicircle is × 360⁰.

________________

Answer:

a = 117°

Step-by-step explanation:

The exterior angle of a triangle = the sum of the remote interior angles.

a + 25° = (a - 47°) + (a - 45°)

a + 25° =  (a + a) + (-47 - 45)

a + 25° = 2a - 92°

-2a        =  -2a        

-a  +25   =    -92

      -25  =     -25    

-a            =  -117°

a = 117°

Answer:

(-2,6)

Step-by-step explanation:

Since both of the equations are equal to y, we can set these equations equal to each other. This means that the new equation using substitution is -8x-10=-6x-6.

-8x=-6x+4

-2x=4

x=-2

This means that the x value is -2. Then, to find the y value, substitute -2 into the first equation (the second equation also works if you want to). So, the equation looks like y=-8(-2)-10. Solve this and it gives you y=6. Therefore, the final coordinate pair is (-2,6).

x=12

Step-by-step explanation:

Using the external angle theorem (external angle = sum of interior angles that are NOT adjacent to the external angle you are finding), we can set up an equation...

140=3x+4+8x+4

Start by combining like terms...

140=11x+8

Subtract 8 from both sides

132=11x

Divide both sides by 11

The total cost of canvas required to make the tent at the rate of Rs. 15 per square meter is; Rs. 24,997

We are told that the bottom part of the tent house is a square cuboid up to a height of 10 m.

Thereafter, it is a pyramid.

Now, formula for volume of a cuboid is;

V = lwh

V = 20 * 20 * 10

V = 4000 m³

Formula for volume of a pyramid is;

V = lwh/3

V = (20 * 20 * h)/3

V = 400h/3

Total volume is 4800 of the entire tent house. Thus;

4000 + (400h/3) = 4800

400h/3 = 800

h = (800 * 3)/400

h = 6 m

Now, from online calculation, the surface area of the pyramid excluding the base is;

TSA_p = 466.48 m²

Total surface area of cuboid excluding the top is;

S.A = 1200 m²

Total surface area of canvas = 1200 + 466.48 = 1666.48 m²

Since cost per sq.m is Rs. 15 per m², then;

Total cost = 15 * 1666.48

Total Cost = Rs. 24,997

Answer:

[tex]y=e^x+3[/tex]

Step-by-step explanation:

By inspection, we can see that the curve crosses the y-axis at (0, 4)

Therefore, when x = 0, y = 4

Inputting x = 0 into the equations:

[tex]y=e^{x-3} \implies y=e^{-3}[/tex]

[tex]y=e^x+3 \implies y=e^0+3=1+3=4[/tex]

[tex]y=e^{x+3} \implies y=e^4[/tex]

[tex]y=e^{x-3}+3^3=e^{-3}+27[/tex]

Therefore, the only equation that gives y = 4 when x = 0 is [tex]y=e^x+3[/tex]

Check option B

[tex]\\ \rm\longmapsto y=e^x+3[/tex]

Put values

[tex]\\ \rm\longmapsto y=e^0+3=1+3=4[/tex]

Hence option B is correct

Answer:

y=2x+3

Step-by-step explanation:

Hi there!

We want to write the equation of the line

We are given that the y-intercept of the line is (0,3) and that the line also goes through the point (2,7)
There are many ways to write the equation of the line, but the most common way is slope-intercept form, which is given as y=mx+b, where m is the slope and b is the y intercept

The value of b is actually the value of y in the point making point of the y intercept
In this case, that point would be 3

So the value of b in this case is 3

Substitute 3 as b into the equation:
y=mx+3

Now we need to find m

As the equation passes through the point (2,7), we can use it to help solve for the value of m

Substitute 2 as x and 7 as y into the equation:

7=2m+3

Subtract 3 from both sides

4=2m

Divide both sides by 2

m=2

Substitute 2 as m into the equation:

y=2x+3

Hope this helps!
