Answer:

y = 3x + 8.

y = 3x - 8

Step-by-step explanation:

The slope of the tangent to the curve at a given point is obtained from the derivative.

xy = 3

y = 3/x

y = 3 x^-1

y' = -3x^-2

The slope of the normal (which is perpendicular to the tangent)

= -1 / -3x^-2 = 1/3 x^2.

Consider the given line:

3x - y - 2 = 0

y = 3x - 2 , so the slope of this line = 3.

Now this line is parallel to the normal  so 1/3 x^2 = 3

Therefore  x^2 = 9  and x = -3, 3.

Find the equations of the normals:

At x = -3, y = 3/-3 = -1, which gives the equation:

y - (-1) = 3(x - -3)

y = 3x + 8.

At x = 3 , y = 1

y - 1 = 3(x - 3)

y = 3x - 8.

Answer:

Choice D

Step-by-step explanation:

First we should find the slope of the equation, so since it's perpendicular to the other equation that means it's the opposite and the reciprocal of that slope. So the slope is [tex]\frac{9}{4}[/tex].

Now we have to find the y-intercept. We already know the x-intercept, so we could use that to find the y-intercept. For that we need to know the slope and one ordered pair, which is (36,0). Then we plug into this formula  [tex]y=mx+b[/tex].

[tex]y=mx+b\\0=\frac{9}{4}(36)+b\\0=81+b\\b=-81[/tex]

So now that we found the y-intercept we just have to put it all together....

[tex]y=\frac{9}{4}x-81[/tex]

Answer:

Point (3, 2) is in the solution set of the quadratic inequality

Step-by-step explanation:

From the given figure

∵ The line the inequality is a solid line

∴ The solution set of inequality have all the points on the line and

   the points on the shaded area

→ We can choose any point on the line or on the red area

∵ Point (3, 2) is the vertex of the parabola

∴ Point (3, 2) is in the solution set of the quadratic inequality

Answer:

see explanation

Step-by-step explanation:

The translation < - 3, - 2 >

Means subtract  3 ( a shift left ) from the x- coordinate and subtract -2 ( a shift down ) from the y- coordinate.

E(3, 6 ) → E'(3 - 3, 6 - 2 ) → E'(0, 4 )

F(1, 0 ) → F'(1 - 3, 0 - 2 ) → F'(- 2, - 2 )

G(- 1, 3 ) → G'(- 1 - 3, 3 - 2 ) → G'(- 4, 1 )

Answer:

A right triangle

Step-by-step explanation:

A right triangle would meet these characteristics. A triangle's inner angles always add up to be 180 degrees. A right triangle has one angle at 90 degrees meaning the other two angles need to be less than 90 degrees and sum up to be 90 degrees. This would indicate that both of these angles' exterior angles would be obtuse because they would be wider than 90 degrees.

Answer:

Clare failed to flip the inequality when dividing by a negative number

Step-by-step explanation:

-4x+3 < 23

Subtract 3 from each side

-4x+3-3 < 23-3

-4x < 20

Divide each side by -4, remembering to flip the inequality

-4x/-4 > 20/-4

x > -5

Clare failed to flip the inequality when dividing by a negative number

Answer:

20:46 or 20 to 46

Answer:

250

Step-by-step explanation:

you have to use the fact that the big triangle and the small triangle are similar and write the proportions

[tex]\frac{125}{10} =\frac{AB}{10}[/tex]  we took half of the side because of ΔABD and ΔBD..

AB= (125*10)/10=125

is AB =125 then AC is duble AC= 2*125=250

Answer:

$734.40

Step-by-step explanation:

y=9,000(1.04)^t is our equation for this.

The 9,000 is the starting amount.

1.04 is the 4% since 4% is 4/100 which equals 0.04, then we add 1 to that since it's increasing in value.

y represents our output.

t represents time (in years for this equation)

Since they give us the amount of years since he deposited the $9,000, we put the number they gave us (2 years) into the equation, replacing t.

y=9,000(1.04)^2

Put the right side into a calculator and it gives you 9734.4.

That's the total amount he has now, so to find how much he earned we subtract the starting amount (9000).

734.4.

Edward earned $734.40.

Answer:

the answer is 29 square yards. took the test got it right

Step-by-step explanation:

The total material needed to cover both is 29 square yards.

A triangle is a polygon that has three sides and three vertices. It is one of the basic figures in geometry.

Vertices of rectangular pool are (0, 4), (4, 10), (7, 8), and (3, 2).

[tex]AB=\sqrt{(7-3)^{2}+(8-2)^{2}}\\\\= \sqrt{16+36}\\\\=\sqrt{52} =CD[/tex]

[tex]BC=\sqrt{(7-4)^{2}+(8-10)^{2}}\\=\sqrt{9+4}\\\\=\sqrt{13} =DA[/tex]

To find the area of rectangular pool

=Length × Breadth

=√52 ×√13=13×2

=26 sq. yard

Vertices of triangle given are P(5,2),Q(7,2) and R(7,5).

PQ= 2 units, QR= 3 units

Area of right triangle PQR = 1/2 ×PQ×PR

Area =1/2×2×3= 3 sq. yards

To find total material needed to cover( that includes bot rectangular pool and triangular hot tub)

= Area of rectangle + Area of right triangle

=26+3=29 square yards
