Step-by-step explanation:

that is a college question ?

oh my ...

to clarify :

perpendicular means intersecting or touching at a right angle (90°).

bisector means it is a line that cuts the other line in half.

1.

because of the bisector this means DF = FC = DC/2.

so, since FC = 17, so is DF (=y) = 17.

2.

for the same reason

2x - 3 = x + 8

x - 3 = 8

x = 11

the angle must be 90°.

so,

5y = 90

y = 18

3.

for the same reason

10 = 4a

a = 10/4 = 2.5

4.

for the given reasons of 1-3, this figure is a kite. that means the left side is a mirror image of the right side. so, all the lengths on one side are equation to the lengths of the other side.

x - 11 = 19

x = 30

5.

for the same reasons

3y + 5 = 26

3y = 21

y = 7

6.

the perimeter of EDP is then

EP + DP + ED = 19 + 19 + (9 + 9) = 56

because ED = EC + CD

and for the above reasons EC = CD = 9

so, ED = 9 + 9 = 18

7.

the perimeter of EDQ is then

EQ + DQ + ED = 26 + 26 + 18 = 70

8.

for the same reasons as above

x = 90°

9.

remember, the sum of all angles in a triangle is always 180°.

180 = 90 + 55 + y

y = 180 - 90 - 55 = 35°

10.

180 = y + M + z = 35 + (55+71) + z = 161 + z

z = 180 - 161 = 19°

Answer:

188 cents or $1.88

Step-by-step explanation:

We first want to find how many cents per one inch, and we do this by dividing 17 from 68 (68/17). This gets us 4 cents per inch. Now we need to multiply 4 by 47 (4 x 47). Now we get 188 cents. The equation for this would be y = 4x

Answer:

x > 1

Step-by-step explanation:

I  am solving this equation, not including the "_" in the equation.

-3(x+2)<-9

Multiply both sides by -1 to reverse the inequality.

3(x+2)>9

Divide by 3

x+2>3

Subtract

x>1

The size of each angle of triangle, starting with the largest 90°, 45° and 45°.

Polygon which has three sides and three vertices is called as triangle.

Sum of all the angles of the triangle is 180°.

Given that a right angled triangle has two equal sides.

And the largest triangle of right angled triangle is 90°.

Right angled triangle which has two equal sides can be called right angled isosceles triangle.

And if one angle of isosceles triangle have angle is 90°. Then the rest of the two angle will be 45°.

Therefore, The rest of these two angles of the right angled triangle are 45⁰.

The amount of sample after 25 years and the half life are given as 51.8 g and 12.83 years respectively.

An exponentially decaying function has a general form f(x) = (1 -r)ˣ, where r is called the decay rate. it can be found by having any two values of x for which f(x) is known.

The given function for the decay of an isotope is given as A(t) = 200[tex]e^-0.054t[/tex].

Now, the given problem can be solved as follows,

(a) The amount of sample after 25 years is given as,

A(25) = 200[tex]e^{-0.054 \times 25}[/tex]

         = 200[tex]e^{-1.35}[/tex]

         = 200 × 0.259                      

         = 51.8

(b) The half life can be calculated as,

100 =  200[tex]e^{-0.054t}[/tex]

=> [tex]e^{-0.054t}[/tex] = 1/2

=> t = 12.83

Answer:

4x  +  1   -  2/x  +  6/(20x³ - 15x² -15x+16)

Step-by-step explanation:

                4x  +  1   -  2/x  +  6/(20x³ - 15x² -15x+16)

             ________________

5x ²-5x | 20x³ - 15x² -15x+16

1            -(20x³ - 20x²)                      ==> -15x²-(-20x²)= -15x²+20x² = 5x²

                         5x² - 15x

2                       -(5x² - 5x)                 ==> -15x-(-5x)= -15x+5x = -10x

3                                -(10x+10)

                                           6           ==> 16-10 = 6           

1: At step 1, (4x) * (5x²-5x) = (20x³ - 20x²)

2: At step 2, 1 * (5x² - 5x) = 5x² - 5x

The side lengths of the triangle are 11.1, 21.4, and 18.5 units.

In a right-angled triangle, the square of the hypotenuse side is equal to the sum of the squares of the other two sides, according to Pythagoras's Theorem.

The given sides of the right triangle are 3m, 2m+14, and 5m.

As per the Pythagorean theorem, it follows:

(2m + 14)² = (3m)² + (5m)²

4m² + 196 + 56m = 9m² + 25m²

30m² -56m - 196 = 0

15m² - 28m - 98 = 0

[tex]m=\frac{-(-28)\pm\sqrt{(-28)^2-4(15)(-98)}}{2(15)}\\\\m=\frac{28\pm\sqrt{6664}}{2(15)}\\\\m =\frac{28\pm81.6}{2(15)}\\\\m=3.7\text{ or } m=-1.8[/tex]

Since the lengths cannot be negative, the value of m is m = 3.7.

Therefore, the side lengths of the triangle are:

3m = 3(3.7)

= 11.1

2m + 14

= 2(3.7) + 14

= 21.4

and,

5m

=5(3.7)

Step-by-step explanation:

Using the Green's Theorem, the one along which the work done by the force is 11π/16.

In the given question we have to find the one along which the work done by the force is the greatest.

The given closed curves in the plane is

[tex]F(x,y)=\left(\frac{x^{2}y}{4} + \frac{y^3}{3}\right)\hat{i}+x\hat{j}[/tex]

Suppose C be a simple smooth closed curve in the plane. It is also oriented counterclockwise.

Let S be the interior of C.

Let P = [tex]\frac{x^{2}y}{4} + \frac{y^3}{3}[/tex] and Q = x

So the partial differentiation is

[tex]\frac{\partial P}{\partial y}=\frac{x^2}{4}+y^2[/tex] and  [tex]\frac{\partial Q}{\partial x}[/tex] = 1

By the Green's Theorem, work done by F is given as

W= [tex]\oint \vec{F}d\vec{r}[/tex]

W= [tex]\iint_{S}\left ( \frac{\partial Q}{\partial x}-\frac{\partial P}{\partial y} \right )dxdy[/tex]

W= [tex]\iint_{S}\left ( 1-\frac{x^2}{y}-y^2 \right )dxdy[/tex]

Let C = x^2+y^2 = 1 and

x = rcosθ, y = rsinθ

0≤r≤1; 0≤θ≤2π

There;

W = [tex]\int_{r=0}^{1}\int_{\theta=0}^{2\pi}\left ( 1-\frac{r^2\cos^2\theta}{4}-r^2\sin^2\theta \right )\left|\frac{\partial(x,y)}{\partial{r,\theta}}\right|d\theta dr[/tex]

and [tex]\frac{\partial (x,y)}{\partial(r, \theta)}=\left|\begin{matrix}\cos\theta &-r\sin\theta \\ \sin\theta & r\cos\theta\end{matrix} \right |[/tex] = r

Thus;

W = [tex]\int_{r=0}^{1}\int_{\theta=0}^{2\pi}\left ( 1-\frac{r^2\cos^2\theta}{4}-r^2\sin^2\theta \right )rd\theta dr[/tex]

After solving

W = 11π/16

The value(s) of a where the tangent line to the graph of the function f(x) = -11x + is parallel to the line y = -19x - 18 is x=1,-1.

What is Slope of function?

Finding the rate at which the value of y (the dependent variable) changes in relation to x is what this method entails (independent variable). The slope itself identifies the line's slope and direction. Write the equation of the line in slope-intercept form to determine the slope from the equation. Utilize inverse procedures to find y, then write it as y=mx+b. Since the slope is the x variable's coefficient, or the number before x, you can thus readily observe the slope.
