Answer:

<em>(-6, 0) and  (0, 1.5)</em>

<em></em>

Step-by-step explanation:

The equation of the line in pint slope form is expressed as;

y-y0= m(x-x0)

m is the slope

(x0, y0) is the point on the line

Given

m = 1/4

(x0, y0) = (6,3)

Substitute into the formula;

y - 3 =  1/4(x-6)

4(y-3) = x - 6

4y - 12 = x-6

4y - x = -6+12

4y - x = 6

x = 4y - 6

To get the points to plot, we will find the x and y-intercept of the resulting expression.

For the x-intercept,

at y = 0

x = 4(0) - 6

x = -6

Hence the x-intercept is at (-6, 0)

For the y-intercept,

at x = 0

0 = 4y - 6

4y = 6

y = 6/4

y = 3/2

y = 1.5

Hence the y-intercept is at (0, 1.5)

<em>Hence the required points to plot to get the required line are  (-6, 0) and  (0, 1.5)</em>

backyard garden rectangular in shape. determine the best length and width(in feet). how many feet of fencing would be needed? us

L = building side
W = non-building side

P = 2W + L = 42 (note only one L because the other L is the building itself)

Solve for L:

L = 42 - 2W


Area = l*w
Area = (42-2W)W = 42W - 2W2

Let area be y, so y = -2W2 +42W

Note this is a parabola pointing down because the coefficient of the W2 is negative. That makes the vertex the maximum for which we are searching.

Vertex of this parabola is at W=-b/2a, if the quadratic is aW2 + bW + c = 0

a = -2
b = 42

W = -42/(2*-2) = -42/-4 = 10.5

W = 10.5
L = 42-2(10.5) = 42-21 = 21

Area = L*W = 21 * 10.5

A = 220.5 ft2

The ages Edna, and Elsa are consecutive integers. The sum of their ages is 114. What are their ages?
OLEGan [10]

Answer:

Edna = 56.5

Elsa = 57.5

Step-by-step explanation:

Represent Edna age with x; Elsa age will be x + 1

So,

x + x + 1 = 114

2x + 1 = 114

Make 2x the subject

2x = 114 - 1

2x = 113

Solve for x

x = 113/2

x = 56.5

Elsa age is calculated as thus;

Elsa = x + 1

Elsa = 56.5 + 1

Elsa = 57.5

Geometry . Cosines / sines. Find a and round to the nearest 10th
Lorico [155]

This is the good part of Trigonometry, actually measuring triangles. It's much better than all the identities around sine and cosine and the rest, which actually have more to do with circles than triangles.

This part of trig has a short menu:

Law of Cosines. Three ways to write it, one is c^2 =a^2+b^2-2ab \cos C

Law of Sines: \dfrac{a}{\sin A} = \dfrac{b}{\sin B} = \dfrac{c}{\sin C}

Triangle angles: A+B+C=180^\circ

and two special cases of the Law of Cosines, the Pythagorean Theorem

C=90^\circ, \quad \quad c^2=a^2+b^2

and the Collinear Points Theorem:

C=180^\circ, \quad \quad c^2=a^2+b^2 - 2 a b \cos 180^\circ = a^2+b^2+2ab=(a+b)^2

c = a+b

Here we choose Triangle Angles followed by Law of Sines:

A = 180 - 105 -15 = 60 degrees

\dfrac{a}{\sin 60^\circ}= \dfrac{2}{\sin 105^\circ}

a= \dfrac{2 \sin 60^\circ}{\sin 105^\circ} = 1.793...

Answer: 1.8 cm

When I was a student we'd be expected to get \sin 105^\circ exactly and get

a = 3 \sqrt{2} - \sqrt 6

But that was before online homework.

The density of an object with mass m and volume V is .
AlexFokin [52]

Answer:

The answer is

<h2>21.45 g/cm³</h2>

Step-by-step explanation:

The density of a substance can be found by using the formula

density =  \frac{mass}{volume}  \\

From the question

mass of platinum = 214.5 g

volume = 10 cm³

It's density is

density =  \frac{214.5}{10}  \\

We have the final answer as

<h3>21.45 g/cm³</h3>

Hope this helps you
