Linear equations - a reminder
If I was to sketch the graph of
y = 4x + 2
what would the graph look like?
Would it be a straight line or a curved line?
Where would it cross the y-axis?
What does the 4 in 4x tell us?

Answers

Answer 1

Answer:

Straight line

Step-by-step explanation: The 4x tells us the slope it means up 4 right 1 it would cross the y axis at 2 since its the y intercept

A women buys a coat through the mail for $250 plus 9% sale tax. If another 10% is added onto this total for shipping and handling, what is the total cost of the coat ?

Answers

Answer:

Find 9% of 250 by turning 9% into a decimal.

.09 x 250 gives you 22.50

add 22.50 to 250

now you have 272.50

now find 10% of 272.50 by converting 10% into a decimal.

.10 x 272.50 gives you 27.25

Add that to 272.50 and you total cost is

$299.75

Find the slope of the tangent line to the given polar curve at the point specified by the value of θ

r = 9 + 8 cos(θ), θ = π/3

Answers

The given curve has equation

r(θ) = 9 + 8 cos(θ)

and its derivative is

dr/dθ = -8 sin(θ)

When θ = π/3, we have r (π/3) = 13, and dr/dθ (π/3) = -4√3.

Differentiate these with respect to θ :

dy/dθ = dr/dθ sin(θ) + r(θ) cos(θ)

dx/dθ = dr/dθ cos(θ) - r(θ) sin(θ)

In polar coordinates, we have

y(θ) = r(θ) sin(θ)

x(θ) = r(θ) cos(θ)

and when θ = π/3, we have y (π/3) = 13√3/2 and x (π/3) = 13/2.

The slope of the tangent line to the curve is dy/dx. By the chain rule,

dy/dx = dy/dθ • dθ/dx = (dy/dθ) / (dx/dθ)

dy/dx = (dr/dθ sin(θ) + r(θ) cos(θ)) / (dr/dθ cos(θ) - r(θ) sin(θ))

When θ = π/3, the slope is

dy/dx = (-4√3 sin(π/3) + 13 cos(π/3)) / (-4√3 cos(π/3) - 13 sin(π/3))

dy/dx = (-4√3 (√3/2) + 13 (1/2)) / (-4√3 (1/2) - 13 (√3/2))

dy/dx = - 1/(17√3)

So, the tangent line has slope -1/(17√3) and passes through (13/2, 13√3/2). Using the point-slope formula, its equation is

y - 13√3/2 = -1/(17√3) (x - 13/2)

y = -(x - 338)/(17√3)

Graph the lines: y= 4x, y = – 4, and x = - 2.

Answers

How can we answer this
Attached is a screenshot of the graphed lines.

I graphed the line, y = 4x, by using the y-intercept (0 ,0), and used the slope (m = 4) to plot other points: {(-1, -4), (1, 4)}.

For y = -4, it is a horizontal line (y = b) with a zero slope. Therefore, regardless of the x-value, its corresponding y-coordinate will be the same (y = -4). To graph the line for y = -4, start at y = -4 and create a horizontal line from there.

For x = -2, it is a vertical line (x = a) with an undefined slope. A vertical line has undefined slope because all points the line have the same x-coordinate. Thus, regardless of the y-value, its corresponding x-coordinate will always be x = -2. To graph the graph, I started at point (-2, 0), and created a vertical line from there.

The length of side ST of the triangle SRT using concept of similar triangles is; ST = 22 km

How to find Length of Similar Triangles?

We are given a Triangle PQR.

In Triangle PQR, Side PQ = 16 kilometers and side PR = 24 kilometers.

In Triangle SRT, Side RT = 33 kilometers.

Using concept of ratio of similar triangles, we can say that;

ST/RT = PQ/PR

Thus;

ST = RT * (PQ/PR)

ST = 33 * (16/24)

ST = 22 Km

Answers

Answer:

∠ 5 = 122° , ∠ 6 = 58°

Step-by-step explanation:

∠ 5 and 122° are vertically opposite and are congruent , then

∠ 5 = 122°

∠ 5 and ∠ 6 are same- side interior angles and sum to 180°

∠ 5 + ∠ 6 = 180° , that is

122° + ∠ 6 = 180° ( subtract 122° from both sides )
