Answer:

70°

Step-by-step explanation:

<GER and IGE< are supplementary angles which means that their sum is equal to 180°

180 - 130 = 70°

Answer:

9

Step-by-step explanation:

The triangle provided is an equilateral one, which means that the length of all sides is equal.

Let's start by taking two and finding x.

8x+1 = 3x+6 (Subtract 3x from both sides)

5x+1 = 6 (Subtract 1 from both sides)

5x = 5 (Divide 5 from both sides)

x = 1

Now we substitute x in all the equations to find the length.

8(1) + 1 = 9

3(1) + 6 = 9

4(1) + 5 = 9

Length = 9

as length is 14m

so area of square plot =14^2=196m^2

final ans/area of plot=196m^2

Answer:

x=1

Step-by-step explanation:

We are given that

[tex]\frac{2x^3}{3}+2x^2-6x+4[/tex]

We have to find the value of x for which function is minimum.

Differentiate w.r.t x

[tex]f'(x)=2x^2+4x-6[/tex]

Substitute f'(x)=0

[tex]2x^2+4x-6=0[/tex]

[tex]x^2+2x-3=0[/tex]

[tex]x^2+3x-x-3=0[/tex]

[tex]x(x+3)-1(x+3)=0[/tex]

[tex](x-1)(x+3)=0[/tex]

[tex]x=1,-3[/tex]

Again, differentiate w.r.t x

[tex]f''(x)=4x+4[/tex]

[tex]f''(1)=4(1)+4=8>0[/tex]

[tex]f''(-3)=4(-3)+4=-8<0[/tex]

Hence, the function is minimum at x=1

Answer:

yes

Answer:

the solution to the equation is 8.  Any value apart from 8 is not a solution

Step-by-step explanation:

Given the equation

6/3x+2 - 1/x-4 = 0

6/3x+2 = 1/x-4

Cross multiply

6(x-4) = 3x+2

6x - 24 = 3x+2

6x-3x = 2 + 24

3x = 24

x = 24/3

x = 8

Hence the solution to the equation is 8.  Any value apart from 8 is not a solution

Answer:

1,2 = 1,negative2

3,6 = 3,negative 6

-1,2 = negative 1, negative 2

-2,-2 = negative2, 2

Step-by-step explanation:

Sorry all i could do was reflect the coordinates across the x-axis.

The figure reflected along x-axis will have vertices A(1, -2), B (3, -6), C(-1, -2), and D(-2, 2).

When we reflect a figure along the x-axis the coordinate point of y changes its sign, (x, y) becomes (x, - y).

Think of holding the x-axis with two fingers and rotating it.

Given, we reflect a figure with vertices A(1,2) B (3,6), C(-1,2), and D(-2,-2)

across the x-axis.

∴ The rotated coordinate will be A(1, -2), B (3, -6), C(-1, -2), and D(-2, 2).

Answer:

m=−bd+t

Step-by-step explanation:

t=bd+m

flip equation

bd+m=t

Step 2: Add -bd to both sides.

bd+m+−bd=t+−bd

m=−bd+t

On solving for M, we get -  

M = t - bd

We have the following expression -

t = bd + M.

We have to solve for ' M '.

On solving, we get -

nx + a = [tex]$\pi[/tex]

x =  [tex]$\frac{\pi -a}{n}[/tex]

According to the question, we have -

t = bd + M

t - bd = M

M = t - bd

Hence, on solving for M, we get -  

M = t - bd

Answer:

a) The rate of change of the brightness after t days is [tex]B^{\prime}(t) = 0.204525\pi\cos{(0.4545\pi t)}[/tex]

b) The rate of increase after one day is of 0.0915.

Step-by-step explanation:

The brightness after t days is given by:

[tex]B(t) = 4.2 + 0.45\sin{(\frac{2\pi t}{4.4})} = 4.2 + 0.45\sin{(0.4545\pi t)}[/tex]

A) Find the rate of change of the brightness after t days.

This is [tex]B^{\prime}(t)[/tex]

The derivative of a constant is 0, the derivative of [tex]\sin{at}[/tex] is [tex]a\cos{at}[/tex]

So, in this case, we have that:

[tex]B^{\prime}(t) = 0.45*0.4545\pi\cos{(0.4545\pi t)} = 0.204525\pi\cos{(0.4545\pi t)}[/tex]

The rate of change of the brightness after t days is [tex]B^{\prime}(t) = 0.204525\pi\cos{(0.4545\pi t)}[/tex]

B) Find the rate of increase after one day.

This is [tex]B^{\prime}(1)[/tex]. So

[tex]B^{\prime}(1) = 0.204525\pi\cos{(0.4545\pi)} = 0.0915[/tex]

The rate of increase after one day is of 0.0915.

Answer:

Work= force(F) * distance (s)

weight is a force and so

F=weight=mass *acceleration due to gravity

=1000*10=10000N

S=?

To find s,

F= ma

a=F/m=10000/10

a=10m/s²

Using Newton's third equation of motion

v²= u²+2as

30²= 20²+2*10*s

900–400=20s

500=20s

s=500/20= 25m

Work =F*s

Work=10000*25

Work= 250000J or 250KJ

Answer:

Angle B and Angle D are both 101 degrees

Step-by-step explanation:

Consecutive Angles in a parallelogram are supplementary (add up to 180 degrees).

Given that fact, we can deduce the measure of angle B.

180-79=101.

Angle D has the same setup since Angle D and C are consecutive along with Angle C and B.

180-79=101.

Therefore, both Angle B and D are 101 degrees.
