There is a line that includes the point (0, 4) and has a slope 1/7of

1 answer:

Y=1/7x + 4
In the equation y=mx+b, m=slope and b=y-intercept. (0,4) is a y-intercept because its x coordinate is 0. Plug in the points.

Determine the value of x for which rls if . m2i = 80 - X; and mz2 = 90 - 2x .

Slav-nsk [51]

Answer:

x = 10

Step-by-step explanation:

For the lines to be parallel, the two angles must have the same measure:

80 - x = 90 - 2x

x = 10 . . . . . . . . . add 2x-80

The value of x must be 10 to make the lines parallel.

An elliptical riding path is to be built on a rectangular piece of property as shown below.

Digiron [165]

The answer above is mostly correct, HOWEVER The ellipse is a vertical ellipse and therefore uses the equation (x^2/b^2)+(y^2/a^2)=1

a=10/2=5

b=8/2=4

put it in the equation and it is (x^2/4^2)+(y^2/5^2)=1

Simplify and the answer is (x^2/16)+(y^2/25)=1

WORTH 15 POINTS PLEASE ANSWER ASAP!! MY YOUNGER BROTHER NEEDS HELP ON THIS!!!! ∧ω∧

Answer:

Therefore,

AD = 7 unit

AE = 600 unit

EF = 30 unit

FB = 5 unit

Ar(EFGH)= 210 unit²

Ar(ABCD)= 4445 unit²

Step-by-step explanation:

Given:

Consider a rectangle ABCD as shown in the figure below where,

Area (ABCD) = 635 × 7 = 4445

Therefore length and width of a rectangle will be

LENGTH =635 = AB

WIDTH = 7 = AD

To Find:

AE =?

EF = ?

FB = ?

Ar(EFGH)=?

Ar(ABCD) =?

Solution:

We know that area of the rectangle is given by

$\textrm{Area of rectangle}= LENGTH\times WIDTH$

$\textrm{Area of rectangle ABCD}= 635\times 7=4445\ unit^{2}$

Substituting the values we get

$\textrm{Area of rectangle AEHD}= AE\times 7\\\\4200=AE\times 7\\\therefore AE=\dfrac{4200}{7}=600$

Similarly for area rectangle FBCG,

$\textrm{Area of rectangle FBCG}= FB\times 7\\\\35=FB\times 7\\\therefore FB=\dfrac{35}{7}=5$

Now we have

AB = 635,

$AE + EF + FB = 635\\\\600+EF+5=635\\\\EF=635 -605=30\\\therefore EF = 30$

Similarly for area rectangle EFGH,

$\textrm{Area of rectangle EFGH}= EF\times 7\\\\=30\times 7=210\ isunit^{2}$

Therefore,

AD = 7 unit

AE = 600 unit

EF = 30 unit

FB = 5 unit

Ar(EFGH)= 210 unit²

Ar(ABCD)= 4445 unit²
