Answer:

[tex]y = 3\left(x-\dfrac{3}{2}\right)^2+\dfrac{41}{4}[/tex]

Step-by-step explanation:

Given equation:

[tex]y = 3x^2 - 9x + 17[/tex]

Factor out 3 from the first 2 terms:

[tex]y = 3(x^2 - 3x) + 17[/tex]

Divide the coefficient of x by 2 and square it:  (-3 ÷ 2)² = 9/4

Add this inside the parentheses and subtract the distributed value of it outside the parentheses:

[tex]y = 3\left(x^2 - 3x+\dfrac{9}{4}\right) + 17-\dfrac{27}{4}[/tex]

Factor the parentheses and combine the constants:

[tex]y = 3\left(x-\dfrac{3}{2}\right)^2+\dfrac{41}{4}[/tex]

Step-by-step explanation:

First, get the area of the rectangle then subtract the triangle, the result will be the shaded area:

area rec = 18 * 11

area rec = 198 cm²

small side of tri = 11 - 5

small side of tri = 6 cm

area tri = (height * width) / 2

area tri = (6 * 18) / 2

area tri = 108 / 2

area tri = 54 cm²

area shaded = 198 - 54

area shaded = 144 cm²

Answer:

-7/8

Step-by-step explanation:

Quadratic formula is ax^2 + bx + c

In this case, x = -b/2a, which is -7/(2(4)) = -7/8

Answer:

x = - [tex]\frac{7}{8}[/tex]

Step-by-step explanation:

given a quadratic in standard form

f(x) = ax² + bx + c (a ≠ 0 )

then the equation of the axis of symmetry is

x = - [tex]\frac{b}{2a}[/tex]

f(x) = 4x² + 7x + 6 ← is in standard form

with a = 4 and b = 7

then equation of axis of symmetry is

Answer:

  (d)  48 yd³

Step-by-step explanation:

The net shown is of a rectangular prism. To find its volume, we need to know its dimensions. The volume will be the product of those dimensions.

__

The area of a rectangle is given by the formula ...

  A = LW

So, if we know one of the dimensions, we can find the other from ...

  W = A/L . . . . . divide by L

For the right-most rectangle, the area is 24 yd², and its length is given as 6 yd. Then the other dimension of that rectangle is ...

  W = 24 yd²/(6 yd) = 4 yd

__

For the left-most rectangle, the area is 12 yd², so its width is ...

  W = 12 yd²/(6 yd) = 2 yd

__

Now we know the dimensions of the cuboid are 6 yd by 4 yd by 2 yd. Its volume is ...

  V = LWH = (6 yd)(4 yd)(2 yd) = 48 yd³

The volume of the solid figure is 48 yd³.

The volume of the solid figure is 48 cubic yd if the length, width, and height of the solid figure are 6, 4, and 2 yd respectively option fourth is correct.

It is defined as the six-faced shape, a type of hexahedron in geometry.

It is a three-dimensional shape. It is also called a cuboid.

We have a net of the solid figure shown in the picture.

From the figure, the face has 24 square yards area and one side length is given, we can calculate the width of this face:

24 = 6×w

w = 4 yd

From the face that has 8 square yards area, we can calculate the height of the solid net:

8 = 4h

h = 2 yd

Volume of the solid net = 6×4×2 = 48 cubic yd

Thus, the volume of the solid figure is 48 cubic yd if the length, width, and height of the solid figure are 6, 4, and 2 yd respectively.

Answer:

3 Hours

Step-by-step explanation:

Plumber A.

Initial fee: $45

Per Hour: $60

Plumber B.

Full rate: $225

To determine the number of hours it will take for both plumbers to charge the same amount you have to start with $45.

Then add 60$ every hour.

$45 + $60 = $105

$105 + $60 = $165

$165 + $60 = $225

Therefore, it takes 3 hours for them to charge the same rate.

keeping in mind that parallel lines have exactly the same slope, let's check for the slope of the equation above

[tex]y= \stackrel{\stackrel{m}{\downarrow }}{4}x+6\qquad \impliedby \begin{array}{|c|ll} \cline{1-1} slope-intercept~form\\ \cline{1-1} \\ y=\underset{y-intercept}{\stackrel{slope\qquad }{\stackrel{\downarrow }{m}x+\underset{\uparrow }{b}}} \\\\ \cline{1-1} \end{array}[/tex]

so we're really looking for the equation of a line whose slope is 4 and passes through (1 , 6)

[tex](\stackrel{x_1}{1}~,~\stackrel{y_1}{6})\hspace{10em} \stackrel{slope}{m} ~=~ 4 \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{6}=\stackrel{m}{4}(x-\stackrel{x_1}{1})[/tex]

[tex]y-6=4x-4\implies y=4x\underset{\stackrel{\uparrow }{b}}{+2}\qquad \impliedby \begin{array}{|c|ll} \cline{1-1} slope-intercept~form\\ \cline{1-1} \\ y=\underset{y-intercept}{\stackrel{slope\qquad }{\stackrel{\downarrow }{m}x+\underset{\uparrow }{b}}} \\\\ \cline{1-1} \end{array}[/tex]

BE and CD are parallel, so the triangles ABE and ACD are similar. Then the following relation holds:

The probability can be calculated as given because there are a total of 52 cards.

It is defined as the ratio of the number of favourable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.

Total number of card = 52

Number of king of heart = 1

P(getting a king of hearts) = 1/52

P(getting a spade) = 13/52 = 1/4

P (getting a 5 or a club) = (16/52) = 4/13

P(getting a 5 or a 7) = 4/52 + 4/52 = 8/52 = 2/13

P(getting a card which is not a spade) = 1 - 1/4 = 3/4

P(getting 11 of clubs) = 1/52

Thus, the probability can be calculated as given because there are a total of 52 cards.

Answer:

remainder = 4

Step-by-step explanation:

using the remainder theorem

when f(x) is divided by (x - a) then the remainder is f(a)

so when f(x) is divided by (x - 7) the remainder is f(7) , that is

f(7) = 7³ - 13(7)² + 40(7) + 18

      = 343 - 13(49) + 280 + 18

      = 343 - 637 + 298

      = 4

Hence, the remainder is [tex]4[/tex].

What is the remainder value?

The remainder is the amount "left over" after performing some computation. In arithmetic, the remainder is the integer "left over" after dividing one integer by another to produce an integer quotient.

Applying the remainder theorem

In general when [tex]f(x)[/tex] is divided by [tex](x - a)[/tex] then the remainder is [tex]f(a)[/tex].

So, here when [tex]f(x)[/tex]  is divided by [tex](x - 7)[/tex]  the remainder is [tex]f(7)[/tex], that is

[tex]f(7)=7^3-13(7)^3+40(7)+18\\=343-13(49)+280+18\\=343-637+298\\=4[/tex]

Hence, the remainder is [tex]4[/tex].
