Step-by-step explanation:

the perimeter (P) is the sum of the 4 sides

(a)

P = a + b + c + d

  = x + 7 + 2x + 2 + 8x + x + 10 ← collect like terms

 = 12x + 19

(b)

If x = 4 , then

P = 12x + 19 = 12(4) + 19 = 48 + 19 = 67

(c)

If x = 2 , then

P = 12x + 19 = 12(2) + 19 = 24 + 19 = 43

(d)

P = a + b + c + d

   = x² + 4x + 8 + 2x² + x ← collect like terms

   = 3x² + 5x + 8

The second vector that's perpendicular to the line we want (call it L) is missing; I'll denote it by ⟨a, b, c⟩.

The cross product of ⟨1, 1, 0⟩ and ⟨a, b, c⟩ is perpendicular to both of these vectors. The direction vector of L will be parallel to this cross product.

Compute the cross product.

⟨1, 1, 0⟩ × ⟨a, b, c⟩ = ⟨1•c - 0•b, 0•a - 1•c, 1•b - 1•a⟩ = ⟨c, -c, b - a⟩

Then the vector equation of L is

L(t) = ⟨c, -c, b - a⟩ t + ⟨-3, 3, -1⟩

As parametric equations, we write

x(t) = ct - 3

y(t) = -ct + 3

z(t) = (b - a) t - 1

Eliminating the parameter above, we get

x + y = (ct - 3) + (-ct + 3) = 0   ⇒   x = -y

and substituting

x = ct - 3   ⇒   t = (x + 3)/c

into z(t), we get

z = (b - a) (x + 3)/c - 1   ⇒   x = c (z + 1)/(b - a) - 3

As symmetric equations, then, we write

x = -y = c (z + 1)/(b - a) - 3

Answer:

What is the amount (to the nearest cent) in the account at the end of three years if the interest rate is 2%? $1,350.68

Step-by-step explanation:

DATA:

Deposits (at beginning of year):

Year 1 = $500

Year 2 = $200

Year 3 = $600

growth factor: z = 1 + r

interest rate is 2% so replace r with 2%. Growth factor equation is now:

z = 1 + 2%

z = 1.02

Year 1 account balance end of year = account balance + growth factor

= $500 + 1.02

= $ 510 account balance at end year 1

Year 2 account balance end of year = (previous year ending balance + current year deposit) * growth factor

= ($510 + $200) * 1.02

= $724.20

Year 3 account balance end of year = (previous year ending balance + current year deposit) * growth factor

= ($724.20 + $600) * 1.02

=$1,350.684

rounded: = $1,350.68 (This answer assumes no money has been withdrawn at any time.)

Answer:

x2 + 8x + 15

Step-by-step explanation:

First - take the first terms of the brackets (so, x and x) and multiply them together: for this example that gives x2.

Outside - take the two outermost terms of the brackets (x and 5) and multiply them together: for this example that gives 5x.

Inside - take the two innermost terms of the brackets (3 and x) and multiply them together: for this example that gives 3x.

Some people may draw lines between terms when doing this (as seen in the diagram above) leaving you with a “crab claw” around the brackets.

Write down everything you have worked out as one long expression:

x2 + 5x + 3x + 15

Then, we will simplify this expression by grouping any “like” terms (this just means adding together any bits with x where they have the same power).

This leaves us with our final answer, which is:           

x2 + 8x + 15

Answer:

Step-by-step explanation:

x < 0

Answer : x is less than or equal to 0

First, the direction of the number line in the graph is the negative number side, so it has to be 0 or less.

If it is less than 0, the dot that starts at the point 0 must have a hollowed out part in the middle. If it is 0 or less, the dot that starts at the point 0 is completely filled with no hollowed middle part.

Since the dot is completely blacked out, the answer is the second option.

Step-by-step explanation:

this just means

q = k×p

and we need to find k.

the sum of both q values when p = 6 and p = 11 is then

k×6 + k×11 = 51

17k = 51

k = 51/17 = 3

so, our equation is

q = 3p

and when q = 72

72 = 3p

p = 72/3 = 24

The coordinates of the vertices of the preimage triangle = (4, 1), (6,1) and (6, -6).

Given the figure of the image triangle.

The coordinates of the image triangle are (-4, 1) , (-6,1) and (-6, -6).

We are asked to find the coordinates of the preimage triangle.

The preimage triangle was reflected over the y-axis .

The image triangle is lying on the 2nd and 3rd quadrants.

So the preimage triangle will lie on the 1st and 4th quadrants.

Then the coordinate (-4,1) will be the image of (4,1).

(-6, 1) will be the image of (6,1) and (-6,-6) will be the image of (6,-6).

Hence the coordinates of the vertices of the preimage triangle = (4, 1), (6,1) and (6, -6).

The original cost of the new robotic toy is given as r.

The cost of the new robotic toy after a 8% markup is: c + 0.08r to show that 8% of r was being added to r to increase the price.

Because both numbers in the equation are related to the same variable, they can be added. When r is used alone, it is considered to be 1r.

The degree measure for angle B is 28° and angle D is 62°.

We are given that:

∠ C = 90°

∠ B = ( 2 x + 10 )°

∠ D = ( 5 x + 17 )°

Now, using the angle sum property of a triangle, we get that:

∠B + ∠ C + ∠ D  = 180°

Substituting the values:

2 x + 10 + 90 + 5 x + 17 = 180

7 x + 117 = 180

7 x = 63

x = 63 / 7

x = 9

∠ B = ( 2 x + 10 )

∠ B = 2(9) + 10

∠ B = 18 + 10

∠ B = 28°

∠ D = ( 5 x + 17 )

∠ D = 5 (9) + 17

∠ D = 45 + 17

∠ D = 62°

Therefore, the degree measure for angle B is 28° and angle D is 62°.

Answer:

3.1.1.  A(-4, 0)   B(0, -2)   E(4, 0)

3.1.2.  k = -16

3.1.3.  (-∞, ∞)

3.1.4.  [-16, ∞)

3.1.5.  [-6, 4]

Step-by-step explanation:

Given functions:

[tex]\begin{cases}f(x)=x^2+k\\g(x)=-2x+8\\h(x)=\dfrac{6}{x-2}+1\end{cases}[/tex]

Points A and B are the x-intercept and y-intercept of function h(x).

Point E is the x-intercept of function g(x).

The x-intercept of function h(x) is when h(x) = 0:

[tex]\begin{aligned}h(x) & = 0\\\implies \dfrac{6}{x-2}+1 & = 0\\\dfrac{6}{x-2} & = -1\\6 & = -1(x-2)\\6 & = -x+2\\4 & = -x\\x & = -4\end{aligned}[/tex]

Therefore, the coordinates of point A are (-4, 0).

The y-intercept of function h(x) is when x = 0:

[tex]\begin{aligned}h(x) & = \dfrac{6}{x-2}+1\\\implies h(0) & = \dfrac{6}{0-2}+1\\ & = -3+1\\& = -2\end{aligned}[/tex]

Therefore, the coordinates of point B are (0, -2).

The x-intercept of function g(x) is when g(x) = 0:

[tex]\begin{aligned}g(x) & = 0\\\implies -2x+8 & = 0\\-2x & = -8\\x & = 4\end{aligned}[/tex]

Therefore, the coordinates of point E are (4, 0).

As function f(x) passes through point C (-6, 20), substitute the point into the equation of the function to find the value of k:

[tex]\begin{aligned}f(-6) & = 20\\\implies (-6)^2 + k & = 20\\36 + k & = 20\\k & = 20 - 36\\k & = -16\end{aligned}[/tex]

Hence, proving that the value of k is -16.

The domain is the set of all possible input values (x-values).

The domain of function f(x) is unrestricted, therefore its domain is:

The range is the set of all possible output values (y-values).

The range of function f(x) is restricted, since the minimum point of the parabola is at (0, -16).  Therefore its range is:

[tex]\begin{aligned}g(x) - f(x) & \geq 0\\\implies g(x) &\geq 0+f(x)\\ \implies g(x) & \geq f(x)\end{aligned}[/tex]

Therefore, find the interval for which g(x) is greater than or equal to f(x).

From inspection of the given graph this is between points C and E:

Yes. It is a right-angled triangle.

The dot product, also known as the scalar product, is an algebraic operation that takes two sequences of numbers of equal length (often coordinate vectors) and outputs a single number. The dot product of two vectors' Cartesian coordinates is frequently used in Euclidean geometry. Although other inner products can be defined in Euclidean space, it is frequently referred to as the inner product (or, less frequently, projection product) of Euclidean space (see Inner product space for more).

The sum of the products of the matching entries of the two number sequences is the dot product, according to algebra. B, it is the result of adding the cosine of the angle between the two vectors and the Euclidean magnitudes of the two vectors.

The vectors that make up the triangle must first be located. The vertices are subtracted to achieve this.

QP=(2,0,-4)-(1,-3,-2)=(1,3,-2)

PR=(1,-3,-2)-(6,-2,-5)=(-5,-1,3)

RQ=(6,-2,-5)-(2,0,-4)=(4,-2,-1)

QP.PR = (1, 3, -2).(-5, -1, 3) = -5-3-6= -14

PR.RQ = (-5, -1, 3).(4, -2, -1) = -20+2-3 = -21

RQ.QP = (4, -2, -1).(1, 3, -2) = 4-6+2 = 0

Calculate the dot products to see if these vectors are perpendicular now.

They are perpendicular if the dot product of two vectors equals zero. As you can see, RQ.QP is zero in your triangle, which supports this. Consequently, a right-angled triangle results.
