if they are similar triangles this means that the relation between the segments RP-FH and GF-RQ

so the first relation is:

so the secon relation will be:

So the solution is numeral B)

The solution to the system of equations is (-2, -3).

Solve one of the equations for one of the variables. In this case, we can solve the first equation for y to get y = 3x + 3.

Substitute that expression into the other equation. We can then substitute this expression into the second equation to get 3x + 3 = x - 1.

Solve the resulting equation. This simplifies to 2x = -4, so x = -2.

Substitute the solution to this equation back into one of the original equations to find the other variable. We can substitute the value of x = -2 into the first equation to get y = 3(-2) + 3 = -3.

Write the solution as an ordered pair. The solution to the system of equations is (-2, -3).

To solve for the vertical displacement at points A and B when members AE and BD are damaged, we need to make some assumptions and simplify the problem. Here are the assumptions:

The structure is statically determinate.

The members are initially undamaged and behave as linear elastic elements.

The deformation caused by damage in members AE and BD is negligible compared to the overall deformation of the structure.

The load q is uniformly distributed on the structure.

Now, let's proceed with the solution:

Calculate the reactions at points C and D:

Since the structure is in self-equilibrium, the sum of vertical forces at point C and horizontal forces at point D must be zero.

ΣFy = 0:

RA + RB = 0

RA = -RB

ΣFx = 0:

HA - HD = 0

HA = HD

Determine the vertical displacement at point A:

To calculate the vertical displacement at point A, we will consider the vertical equilibrium of the left half of the structure.

For the left half:

ΣFy = 0:

RA - qL/2 = 0

RA = qL/2

Since HA = HD and HA - RA = 0, we have:

HD = qL/2

Now, consider a free-body diagram of the left half of the structure:

  |<----L/2---->|

  |       q      |

----|--A--|--C--|----

From the free-body diagram:

ΣFy = 0:

RA - qL/2 = 0

RA = qL/2

Using the formula for vertical displacement (δ) in a simply supported beam under a uniformly distributed load:

δ = (5qL^4)/(384EI)

Assuming a linear elastic behavior for the members, we can use the same modulus of elasticity (E) for all members.

Determine the vertical displacement at point B:

To calculate the vertical displacement at point B, we will consider the vertical equilibrium of the right half of the structure.

For the right half:

ΣFy = 0:

RB - qL/2 = 0

RB = qL/2

Since HA = HD and HD - RB = 0, we have:

HA = qL/2

Now, consider a free-body diagram of the right half of the structure:

  |<----L/2---->|

  |       q      |

----|--B--|--D--|----

From the free-body diagram:

ΣFy = 0:

RB - qL/2 = 0

RB = qL/2

Using the formula for vertical displacement (δ) in a simply supported beam under a uniformly distributed load:

δ = (5q\(L^4\))/(384EI)

Assuming a linear elastic behavior for the members, we can use the same modulus of elasticity (E) for all members.

Calculate the vertical displacements at points A and B:

Substituting the appropriate values into the displacement formula, we have:

δ_A = (5q\(L^4\))/(384EI)

δ_B = (5q\(L^4\))/(384EI)

Therefore, the vertical displacements at points A and B, when members AE and BD are damaged, are both given by:

δ_A = (5q\(L^4\))/(384EI)

δ_B = (5q\(L^4\))/(384EI)

Note: This solution assumes that members AE and BD are the only ones affected by the damage and neglects any interaction or redistribution of forces caused by the damage.

It should be noted that the amount that Aaliyah owes her friend after t weeks will be L = 180 - 15t.

It should be noted that from the information, Aaliyah borrowed some money from her friend in order to help buy a new video game system, she originally borrowed $180 and agreed to pay back her friend $15 per week

Therefore, the amount that Aaliyah owes her friend after t weeks will be:

= 180 - 15(t)

L = 180 - 15t.

where t = number of weeks

L = the amount left

Therefore, the amount that Aaliyah owes her friend after t weeks will be L = 180 - 15t.

I hope this helps you

:)

Answer:

/ A = 24°

/ B = 156°

Step-by-step explanation:

Supplementary angles add up to 180°.

_________________________________

Therefore, / A + / B = 180

(9x - 12) + (24x + 60) = 180

9x - 12 + 24x + 60 = 180

33x + 48 = 180

33x = 180 - 48

33x = 132

x = 132/33

x = 12/3

x = 4

_________________________________

/ A = (9x - 12)

= (9(4) - 12)

= (36 - 12)

= 24°

/ B = (24x + 60)

= (24(4) + 60)

= (96 + 60)

= 156°

The area of the figure is 45 sq.mi and the perimeter is 23.5354 mi.

Area is the space occupied by a two dimensional object,

The area and perimeter of the given shape can be determined by dividing it into basic shapes.

The area and the perimeter of the shape given = Area of the rectangle +Area of upper triangle - Area of two small triangles at the bottom

Area of rectangle = 5 mi * 9 mi = 45 sq.mi

Area of upper Triangle = (1/2) *9*3 = 27/2 sq.mi

Area of small Triangle = (1/2) * 3*6 = 9 sq.mi

Area of other small Triangle = (1/2)*3*3 = 9/2 sq.mi

Area of the figure = 45 +13.5 -9-4.5

Area of the figure =  45 sq.mi

Similarly for Perimeter = Perimeter of the rectangle +Perimeter of upper triangle -Perimeter of two small triangles at the bottom

Perimeter = 28 -(3+6+6.708) -(3+3+4.2426) +(3+9+9.486

The slope of the line that divides the region bounded by the parabola \(y=5x-3x^2\)and the x-axis into two regions with equal area is 5.

To find the slope of the line that divides the region into two equal areas, we need to determine the point of intersection between the parabola and the x-axis. Since the line passes through the origin, its equation will be y = mx, where m represents the slope.

Setting the equation of the parabola equal to zero, we find the x-values where the parabola intersects the x-axis. By solving the equation\(5x - 3x^2 = 0\), we get x = 0 and x = 5/3.

To divide the region into two equal areas, the line must pass through the midpoint between these x-values, which is x = 5/6. Plugging this value into the equation of the line, we have y = (5/6)m.

Since the areas on both sides of the line need to be equal, we can set up an equation using definite integrals. By integrating the equation of the parabola from 0 to 5/6 and setting it equal to the integral of the line from 0 to 5/6, we can solve for m. After performing the integration, we find that m = 5.

Therefore, the slope of the line that divides the region into two equal areas is 5.

To solve the equation 3a² = -4a + 15 by factoring, we need to rewrite it in the form of a quadratic equation, set it equal to zero, and then factor it. The solutions to the equation 3a² = -4a + 15 are a = 5/3 and a = -3.

The equation 3a² = -4a + 15 can be rearranged as 3a² + 4a - 15 = 0. Now we can factor the quadratic expression.

To factor the quadratic expression, we need to find two numbers that multiply to give -45 and add up to +4. The numbers that satisfy these conditions are +9 and -5. So, we can write the equation as (3a - 5)(a + 3) = 0.

Setting each factor equal to zero, we have two possible solutions: 3a - 5 = 0 or a + 3 = 0.

Solving these equations, we find a = 5/3 or a = -3.

Therefore, the solutions to the equation 3a² = -4a + 15 are a = 5/3 and a = -3.

Answer:

B) x = √118 mi

Step-by-step explanation:

This is a right triangle, so we can the measure of x using the Pythagorean theorem, which is

a^2 + b^2 = c^2, where

Step 1:  Plug in x and √26 for a and b and 12 for c and simplify:

x^2 + (√26)^2 = 12^2

x^2 + 26 = 144

Step 2:  Subtract 26 from both sides to isolate x^2:

(x^2 + 26 = 144) - 26

x^2 = 118

Step 3:  Take the square root of both sides to isolate x:

√(x^2) = √118

x = √118 mi

the population of province is growing at the rate of 2.91%

the formula of the rate of growth of a population =

[(future population- initial population/initial population)*100]/time

population in 2016 = 4.2 milllion = 4200000

Population predicted in 20 years = 6.65 million = 6650000

so, initial population = 4200000

future population = 6650000

rate of growth = {(6650000- 4200000/4200000)*100]/20

                       = 58.33/20
