Answer:

(a)  [tex](x-2)(x+4)[/tex]

zeros: x = 2, x = -4

vertex: (-1, -9)

(b)  [tex]-(x+2)(x+7)[/tex]

zeros: x = -2, x = -7

vertex = (-4.5, 6.25)

Step-by-step explanation:

To factor a quadratic in the form [tex]ax^2+bx+c[/tex]:

To find zeros of a factored quadratic in the form [tex](ax+b)(cx+d)[/tex]

The midpoint between the two zeros is the x-coordinate of the vertex. To find the y-coordinate of the vertex, substitute this into the given equation.

-------------------------------------------------------------------------------------

Question (a)

Factored

Factor  [tex]y=x^2+2x-8[/tex]

[tex]ac=-8[/tex]  and  [tex]d+e=2[/tex]

[tex]\implies d=4[/tex] and [tex]e=-2[/tex]

Rewrite [tex]2x[/tex] as [tex]+4x-2x[/tex]:

[tex]\implies x^2+4x-2x-8[/tex]

Factorize the first two terms and the last two terms separately:

[tex]\implies x(x+4)-2(x+4)[/tex]

Factor out common term [tex](x+4)[/tex]:

[tex]\implies (x-2)(x+4)[/tex]

Zeros

[tex]\implies (x-2)=0\implies x=2[/tex]

[tex]\implies (x+4)=0\implies x=-4[/tex]

Vertex

[tex]\sf x-value=\dfrac{2+(-4)}{2}=-1[/tex]

[tex]\sf y-value=(-1)^2+2(-1)-8=-9[/tex]

Vertex = (-1, -9)

-------------------------------------------------------------------------------------

Question (b)

Factor  [tex]y=-x^2-9x-14[/tex]

[tex]ac=14[/tex]  and  [tex]d+e=-9[/tex]

[tex]\implies d=-7[/tex] and [tex]e=-2[/tex]

Rewrite [tex]-9x[/tex] as [tex]-7x-2x[/tex]:

[tex]\implies -x^2-7x-2x-14[/tex]

Factorize the first two terms and the last two terms separately:

[tex]\implies -x(x+7)-2(x+7)[/tex]

Factor out common term [tex](x+7)[/tex]:

[tex]\implies (-x-2)(x+7)[/tex]

Factor [tex](-x-2):-(x+2)[/tex]

[tex]\implies -(x+2)(x+7)[/tex]

Zeros

[tex]\implies -(x+2)=0\implies -x-2=0 \implies x=-2[/tex]

[tex]\implies (x+7)=0\implies x=-7[/tex]

Vertex

[tex]\sf x-value=\dfrac{-2-7}{2}=-4.5[/tex]

[tex]\sf y-value=-(-4.5)^2-9(-4.5)-14=6.25[/tex]

Vertex = (-4.5, 6.25)

Answer:

0.125

Step-by-step explanation:

So since we have 1/2 we will convert that to half of a pie... (the half circle)

We need to divide by four so we take that half of a pie and slice it into four parts... each part is now equivalent to our answer...

Equation... (as follows)

0.50 / 4 = 0.125

Answer:

The value of z = -3 or z = 9

Step-by-step explanation:

Given equation => z² – 6z – 27 = 0

=> z² - 9z + 3z - 27 = 0

=> z(z -9 ) +3 (z - 9 ) = 0

=> (z + 3) (z - 9)

=> z = -3 or z = 9

4 1/3

Step-by-step explanation:

this is just a subtraction problem. What you know is that it snowed 5ft yesterday and 2/3ft today. So that means that the amount of more snow yesterday can be calculated with 5 - 2/3ft (this will show how much more snow there was yesterday). The result of this expression would be 4 1/3.

Step-by-step explanation:

x ÷ 7 ÷10 = 3/35

(Use trial & error - since I knew x<7)

6/7 ÷ 10 = 3/35

Answer:

x² + 12x - 160 = 0

x = 8 or x = -20

The dimensions are 2 cm, 11 cm, 17 cm.

Step-by-step explanation:

The volume of the cuboid is the product of the three dimensions.

volume = 2(x + 3)(x + 9)

volume = 2(x² + 12x + 27)

volume = 2x² + 24x + 54

We are told the volume equals 374 cm³.

2x² + 24x + 54 = 374

2x² + 24x - 320 = 0

x² + 12x - 160 = 0

(x - 8)(x + 20) = 0

x - 8 = 0 or x + 20 = 0

x = 8 or x = -20

We do not use x = -20 because it would cause two dimensions to be negative which cannot be.

x = 8

x + 3 = 8 + 3 = 11

x + 9 = 8 + 9 = 17

The dimensions are 2 cm, 11 cm, 17 cm.

Step-by-step explanation:

If the circle is rotated about the vertical axis then it forms the shape of a sphere with the same center.

It deals with the size of geometry, region, and density of the different forms both 2D and 3D.

A circle is rotated around a vertical axis. The circle does not intersect the axis.

Answer:

Total Surface Area

= 384 sq ft

Step-by-step explanation:

To find Total Surface Area, add up the areas of all the sides of the shape. A square based pyramid has five sides, a square bottom and four triangular sides. Luckily all four sides are the same, so just one calculation for these.

Area of square base is given.

A = 144 sq ft

Since the base is a square the length of the side of the square is 12, because 12×12 is 144.

The side of the square base is the base of the triangular side.

Area of a triangle:

A = 1/2•b•h

A = 1/2(12)(10)

A = 60

The area of one triangular face is 60. There are four of these.

A = 4(60)

A = 240

This is the area of all the triangular faces.

Add them all up.

A (TOTAL)

= 144+240

= 384 sq ft

Hey there!

3(x + 19) - 25/5

= 3(15 + 19) - 25/5

= 3(15) + 3(19) - 25/5

= 45 + 57 - 25/5

= 45 + 57 - 5

= 102 - 5

= 97

OR

3(x + 19) - 25/5

= 3(15 + 19) - 25/5
= 3(34) - 25/5

= 102 - 25/5

Answer:

Step-by-step explanation:

In the question we have given an expression that is 3 ( x + 19 ) - 25/5 and value of x is equal to 15 .

And we are asked to find the value expression when value of x is 15 .

Solution : -

[tex] \longmapsto \: 3( x+ 19) - \cancel{\frac{25}{5} }[/tex]

Step 1 : Substituting value of x in given expression and cancelling 25 by 5 :

[tex] \longmapsto \: 3(15 + 19) - 5[/tex]

Step 2 : Solving parenthesis by adding 15 and 19 :

[tex] \longmapsto \: 3(34) - 5[/tex]

Step 3 : By multiplying 3 with 34, we get :

[tex] \longmapsto \: 102 - 5[/tex]

Step 4 : Subtracting 5 from 102 :

[tex] \longmapsto \: \red{ \boxed{ \frak{97}}}[/tex]
