Answer:

  y +2 = (1/4)(x +1)

Step-by-step explanation:

The given line is in slope-intercept form:

  y = mx + b

where the slope (m) is -4 and the y-intercept (b) is +13.

For the perpendicular line, we need a slope that is the opposite reciprocal, or ...

  -1/m = -1/(-4) = 1/4

A suitable form for the desired equation is the point-slope form:

  y -k = m(x -h) . . . . . . line with slope m through point (h, k)

For m=1/4 and (h, k) = (-1, -2), the equation of the line is ...

  y +2 = (1/4)(x +1)

The diagram shows a triangle.

13.4 cm
7.6 cm
Work out the area of the triangle.

Answers

Answer:

Area of the triangle = 12.92 cm²

Step-by-step explanation:

Area of a triangle = [tex]\frac{1}{2}(\text{Base})(\text{Height})[/tex]

From the figure attached,

Length of base of the triangle = 7.6 cm

Length of the height of the triangle = 3.4 cm

Area of the triangle = [tex]\frac{1}{2}(7.6)(3.4)[/tex]

                                 = 12.92 square cm

Given:

Two numbers are 32 and 28.

To find:

The GCF of 32 and 28 and using the GCF find the factor of (32-28).

Solution:

(a)

Two numbers are 32 and 28. The factor form of given numbers are:

[tex]32=2\times 2\times 2\times 2\times 2[/tex]  

[tex]28=2\times 2\times 7[/tex]

Clearly, 2 and 2 are common factors in both.

[tex]GCF(32,28)=2\times 2[/tex]

[tex]GCF(32,28)=4[/tex]

Therefore, the GCF of 32 and 28 is 4.

(b)

Using the GCF we need to find the factor of (32-28).

[tex]32-28=4\times 8-4\times 7[/tex]

Taking out the GCF, we get

[tex]32-28=4\times (8-7)[/tex]

Therefore, [tex]32-28=4\times (8-7)[/tex].

To solve the given question above, we have our conversion factor

1 foot = 0.000305 kilometre

1,612 feet = x km

In the provided sequence there are four terms after expanding the sequence and the sequence is  0 + 3 + 8 + 15.

What is a sequence?

It is defined as the systematic way of representing the data that follows a certain rule of arithmetic.

It is given that:

3

Σ n(n + 2)

n = 0

After expanding the above sequence:

= 0(0 + 2) + 1(1 + 2) + 2(2 + 2) + 3(3 + 2)

= 0 + 3 + 2(4) + 3(5)

= 0 + 3 + 8 + 15

As we can see in the above sequence there are four terms.

Divergent sequences are those in which the terms never stabilize; instead, they constantly increase or decrease as n approaches infinity, approaching either infinity or -infinity.

Thus, in the provided sequence there are four terms after expanding the sequence and the sequence is 0 + 3 + 8 + 15.

Michelle ordered 200 T-shirts to sell at the school carnival. She paid $2.80 per shirt, plus 5% of the total order for shipping. When she sells each T-shirt at the carnival, she adds a 150% markup to the total price she paid for the shirt (including the cost of shipping). What is the selling price of each T-shirt?

Answers

Answer: She should sell each T-Shirt for at least $4.41

Step-by-step explanation:

First you need to figure out what the total cost of the 200 t shirts was plus shipping. so 200 t shirts for 2.8 would cost $560 + a 5% shipping fee ($28) = 588 if she wants to markup by 150. you would then multiply 588 * 1.5 = $882. This would be the final money she wants to make by the end of her school carnival. Divide 882/200 (amnt of t-shirts) to get $4.41 per shirt

A particle moves along a horizontal line. Its position function is s(t) for t is greater than or equal to 0. For each problem, find the velocity function v(t) and the acceleration function a(t).
1. s(t) = -t^4 + 12t^3
2. s(t) = -t^4 + 8t^3

Answers

Answer:

1) Velocity

[tex]v(t) = -4\cdot t^{3}+36\cdot t^{2}[/tex]

Acceleration

[tex]a(t) = -12\cdot t^{2}+72\cdot t[/tex]

2) Velocity

[tex]v(t) = -4\cdot t^{3}+24\cdot t^{2}[/tex]

Acceleration

[tex]a(t) = -12\cdot t^{2}+48\cdot t[/tex]

Step-by-step explanation:

From Physics we remember that velocity ([tex]v(t)[/tex]) and acceleration ([tex]a(t)[/tex]) are the first and second derivatives of the function position in time. That is:

1) Let [tex]s(t) = -t^{4}+12\cdot t^{3}[/tex], where [tex]t \ge 0[/tex]. The functions velocity and aceleration are, respectively:

Velocity

[tex]v(t) = -4\cdot t^{3}+36\cdot t^{2}[/tex]

Acceleration

[tex]a(t) = -12\cdot t^{2}+72\cdot t[/tex]

2) Let [tex]s(t) = -t^{4}+8\cdot t^{3}[/tex], where [tex]t\ge 0[/tex]. The functions velocity and acceleration are, respectively:

Velocity

[tex]v(t) = -4\cdot t^{3}+24\cdot t^{2}[/tex]

Acceleration

[tex]a(t) = -12\cdot t^{2}+48\cdot t[/tex]

Alexander is a stockbroker. He earns 13% commission each week. Last week, he sold 6,400 worth of stocks. If he averages that same amount each week, how much did he make in commission in 2011?

Answers

Answer:

$43,264

Step-by-step explanation:

Given :

% Commission earned per week = 13%

Worth of stock sold last week = 6400

If same amount is averaged each week during 2011 ;

Number of weeks per year = 52

Worth of stock for the year = (6400 * 52) = $332,800

Average Commission for the year = 13% of 332,800

0.13 * 332,800

= $43,264

For a parallelogram, JKLM, the value of x is to be determined.

What is parallelogram?

A parallelogram is a quadrilateral consisting of pairs of parallel sides.

Here,
For the parallelogram, the sum of the adjacent angle is 180°. So,
3x + 20 + 5x - 8 = 180
8x = 180 - 12
x = 168 / 8
x = 21

Thus, the required value of x in the JKLM parallelogram is 21. Option C is correct.
