Answer:

D

Step-by-step explanation:

calculate AB using the distance formula

d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]

with (x₁, y₁ ) = A (4, 2 ) and (x₂, y₂ ) = B (9, 10 )

AB = [tex]\sqrt{(9-4)^2+(10-2)^2}[/tex]

     = [tex]\sqrt{5^2+8^2}[/tex]

     = [tex]\sqrt{25+64}[/tex]

     = [tex]\sqrt{89}[/tex]

     ≈ 9.4 units ( to 1 dec. place )

Answer:

[tex]D:\:about\:9.4\:units[/tex]

Step-by-step explanation:

[tex]d=\sqrt{(x_{2}-x_{1})^2 +(y_{2}-y_{1})^2 }[/tex]

[tex]AB =[/tex] [tex]\sqrt{(9-4)^2+(10-2)^2}[/tex]

[tex]=\sqrt{5^2+8^2}[/tex]

[tex]=\sqrt{25+64}[/tex]

[tex]=\sqrt{89}[/tex]

[tex]9.4\:\:units\:[/tex]

The formula is in a quadratic formula shape: [tex]y = ax^2+bx+c[/tex]

The function is negative since the value 'a' the coefficient of x^2 is negative meaning that the quadratic function is facing downards. If you don't get this explanation, take a look at the diagram I uploaded.

That means the highest point of the graph is its vertex.

But we must find where the vertex is at or the 't' value.

   't' value at which vertex is = [tex]-\frac{b}{2a} =-\frac{16}{2*(-16)} =\frac{1}{2}[/tex]

Now plug this 't' value into h(t) to find the maximum height, and we will get 36 feet.

Hope that helps!

Answer:

5/3, or 1.(6)

Step-by-step explanation:

find slope-intercept form

5x-3y=18

5x=3y+18

3y=5x-18

y=5/3x-6

slope is 5/3, or 1.(6)

The slope is 5/3 or 1.6.

It is the measure of the steepness of a line.

Given that

5x-3y = 18

Rearrange the equation

i.e. 5x-18 = 3y

y = (5/3)x - 6

The general form of the slope-intercept equation is

y = mx+c

By comparing the two equation, we get slope as

Slope of the line,m = 5/3 = 1.6

Hence, the slope of the given line is 1.6.

Answer:

The volume of the prism is 72 cubic cm.

Step-by-step explanation:

This we know because a triangle with sides of 3 units, 4 units, and 5 units must be a 3–4–5 right triangle, the catheti (“legs”) of which are 3 and 4 units. So the area of the base is

3 cm. * 4 cm. / 2 = 6 square cm.

Lastly, the volume of the prism is the base area multiplied by the height:

6 square cm. * 12 cm. = 72 cubic cm.

(x^2-4x)(x-1)

x^3-x^2-4x^2+4x

simplify

x^3-5x^2+4x

Answer:

Expand:

This is in its expanded form.

Simplify:

First do the x and the (x-4)

distribute the x

(x^2-4x)

Then FOIL or draw you grid and multiply out.

x^2 times x = x^3

x^2 times -1 = -x^2

-4x times x = -4x^2

-4x times -1 = 4x

Combine like terms.

x^3 + (-4x^2 -x^2) + 4x

Answer : x^3 - 5x^2 + 4x

Answer:

The total amount of candles is 768.

Step-by-step explanation:

Why? If there are 32 boxes of candles and 24 candles are in each box you would have to multiply 32x24 which is = to 768 candles in each box.

Step-by-step explanation:

sin²(x) + cos²(x) = 1

cos²(x) = 1 - sin²(x)

cos(x/2) = ±sqrt((1 + cos(x))/2)

in our case

sin(x) = 1/4, tan(x) > 0, so cos(x) is positive too.

sin²(x) = 1/4² = 1/16

cos²(x) = 1 - 1/16 = 15/16

cos(x) = sqrt(15)/4

cos(x/2) = sqrt((1 + sqrt(15)/4)/2) = sqrt(1/2 + sqrt(15)/8) =

= sqrt(8/16 + 2×sqrt(15)/16) =

= 1/4 × sqrt(8 + 2×sqrt(15))

Answer:

[tex]x = 5[/tex], [tex]y = -2[/tex]

Step-by-step explanation:

[tex]2x + 5y = 0[/tex]

[tex]3x - 4y = 23[/tex]

By using substitution:

[tex]2x + 5y = 0[/tex]

[tex]2x = -5y[/tex]

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

[tex]3x - 4y = 23[/tex]

[tex]3 (-\frac{5}{2} y) - 4y = 23[/tex]

[tex]-\frac{23}{2} y = 23[/tex]

[tex]y = -2[/tex]

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

[tex]x = -\frac{5}{2} (-2)[/tex]

[tex]x = 5[/tex]

Step-by-step explanation:

in the rhombus shown, there are 4 congruent right triangles because the disgonals of a rhombus are perpendicular and the sides of a rhombus are congruent. We already know that the larger acute angles are all 54 degrees and we can use triangle sum to find that the smaller acute angles are all 36 degrees. Obviously the right angles are 90 degrees, so we can look at the picture and find the marked angles.

Those are quadrilaterals
