Find the value of x for which line a is parallel to line b
Answer:
20
Step-by-step explanation:
Since we are told that line a is parallel to line b, even if it's not visible in the image, we can say that ∠5 = ∠1, since they are formed by the same line crossing parallel lines.
So, we have
∠4 = 3x
∠5 = ∠1 = 6x
Since ∠4 and ∠5 are complementary angles formed by line t, we know their sum is 180 degrees. So,
∠4 + ∠5 = 180
3x + 6x = 180
9x = 180
x = 20
Answer is 20.
The function H(t) = −16t^2 + 112t + 24 shows the height H(t), in feet, of a cannon ball after t seconds. A second cannon ball moves in the air along a path represented by g(t) = 5 + 3.2t, where g(t) is the height, in feet, of the object from the ground at time t seconds.

Dave uses the functionP(d) = 20d - 20 to calculate the net profit of his dog walking business. Where P(d) is the net profit in dollars, and "d" the number of dogs he walks. Interpret the meaning of the equation below using the context of the problem
P(3) = 40
When Dave walks three dogs he will earn a net profit of 40 dollars.
P(3) = 40 in the given problem context implies that Dave makes a net profit of 40 dollars from walking three dogs.
Explanation:In the given problem context, the equation P(3) = 40 means that when Dave walks three dogs (d=3), he makes a net profit of 40 dollars. Dave's profit function is P(d) = 20d - 20. By substituting d with 3 in his profit function, we obtain P(3) = 20*3 - 20, which gives us P(3) = 60 - 20 = 40. Thus, Dave earns a net profit of 40 dollars from walking 3 dogs.

Select "Growth" or "Decay" to classify each function.
Final answer:
Classifying functions involves identifying whether a population is experiencing growth, depicted by exponential or J-curve growth models, or decay, which is often described through logistic or S-curve models. Exponential growth shows unrestricted rapid increases, while logistic growth accounts for environmental limits and a carrying capacity. Age structure diagrams provide further context for the type of population change being observed.
Explanation:
Growth and Decay in Biological Functions
When classifying functions as growth or decay, one must consider the nature of the function in relation to the context of time and population size. For instance, when discussing bacterial growth, Curve A depicting exponential growth is characterized by a population size that increases rapidly over time, often without any constraints. This curve represents a J-curve model on a graph where population size skyrockets as time progresses. On the other hand, Curve B illustrates logistic growth, which follows an S-curve model where the population grows rapidly at first and then slows down as it reaches carrying capacity, a point where growth rate starts to decline.
Different time intervals on a growth curve represent various phases, such as the lag phase, where growth is slow or negligible; the log phase or exponential phase, where the number of cells increases dramatically; the stationary phase, where growth rate is zero due to resource depletion or waste accumulation; and the death phase, where the number of live cells declines.
Various types of growth in organisms can be identified by their structural adaptations or ecological contexts, such as whether they are terrestrial or aquatic, or whether they are deciduous or evergreen plants. Additionally, age structure diagrams for populations can reveal if a population is rapidly growing, growing slowly, stable, or in decline.

For the direct variation such that when y = 2 then x = 3 , find the constant of variation ( k) and then find the value of y when x = - 0.5.
Answer:
k is 2/3 and y is -1/3 when x is -0.5.
Step-by-step explanation:
The direct variation relationship is y = kx, where k is the const. of var.
Subbing 3 for x and 2 for y, 2 = 3k, or k = 2/3.
Now, if x = -0.5, y = (2/3)(-1/2) = -1/3
k is 2/3 and y is -1/3 when x is -0.5.

Big Ed’s car dealership is running a special on 2008 trucks. Big Ed offers financing at a rate of 6.71% on a loan with a term of 36 months, but he requires the customer to make a down payment of 15% of the cost of the vehicle. You are interested in a Car Crusher truck that costs $25,230. Not including the down payment, how much will you pay over the lifetime of the loan? a. $27,924.84 c. $23,735.88 b. $25,789.32 d. $21,445.50 Please select the best answer from the choices provided A B C D
Answer: C
Step-by-step explanation:
25,230 x .15= 3,784.50
25,230- 3,784.50= 21,535
21,535/36= 598.20833
598.20833 x 1.0671= 638.348109
638.348109 x 36= 22,980.5319
Answer:
Letter C $23,735.84.The result varies a few dollars, because during the solution an adjustment was made to the decimals.
Step-by-step explanation:
1. Define the price of the vehicle you are going to buy with the dealer or seller
Principal: $25230
Rate= 6.71%
N= 36 months
Down payment=15% of the cost of the vehicle= (25230*0.15)=$3784.50
25230-3784.50=21445.5
2. Apply the amortization formula to determine the monthly payments. With this taxation, you will determine the payments applied to the principal and the copper of interest.
A=P*(r(1+r)^{n})/((1+r)^{n}-1).
A= amortization or monthly payments.
P=Principal
R=interest rate
N= the total number of months
a. Calculate the monthly interest rate. The annual interest rate is 6.71% percent. Divide it by 12 to get the monthly interest rate. The monthly interest rate is 0.5592 percent (6.71/12 = 0.5592)
A=21445.5*(0,005592 (1+0,005592)^{{36}})/(1+0,005592)^{{36}}-1.
A=21445.5*(0,00683/0,2223)
A=21445.5*0,03072=658.90
Total of the payment= 658.90*36=23720.40
An important postulate in geometry states: "Through Point P, there is only one line parallel to ". What is the equation of line l, parallel to AB that passes through Point X?
Answer:
y=(-5/12)x+(95/12)
Step-by-step explanation:
step 1
Find the slope of the line AB
m=(3-8)/(2+10)=-5/12
step 2
Find the slope of the line parallel to AB
we know that
If two lines are parallel then their slopes are the same
so
the slope is m=-5/12
step 3
Find the equation of the line l parallel to AB that passes through Point X
The equation of the line into point slope form is equal to
y-y1=m(x-x1)
substitute
y-10=(-5/12)(x+5)
y=(-5/12)x-(25/12)+10
y=(-5/12)x+(95/12)
The vertices of ABC are A(-2,2), B(6,2), and C(0,8). The perimeter of ABC
Answer:
The perimeter of the triangle ABC is 22.8 units
Step-by-step explanation:
* Lets study the information in the problem
- There is Δ ABC with vertices:
A (-2 , 2) , B (6 , 2) , C (0 , 8)
- The perimeter of the triangle is the sum of the length of its
three sides
* We must to find the lengths of AB , BC and CD
- The rule to find the distance between 2 points (x1 , y1) and (x2 , y2) is
√[(x2 - x1)² + (y2 - y1)²]
* Lets find the lengths of the three sides
- Length of AB
∵ A = (-2 , 2) and B = (6 , 2)
∴ AB = √[(6 - -2)² + (2 - 2)²] = √8² = 8 units
- Length of BC
∵ B = (6 , 2) and C = (0 , 8)
∴ BC = √[(0 - 6)² + (8 - 2)²] = √[6² + 6²] = √72 = 6√2 units
- Length of AC
∵ A = (-2 , 2) and C = (0 , 8)
∴ AC = √[(0 - -2)² + (8 - 2)²] = √[2² + 6²] = √40 = 2√10 units
* Now lets find the perimeter of the triangle
∵ The perimeter = AB + BD + AC
∴ The perimeter = 8 + 6√2 + 2√10 = 22.8 units
* The perimeter of the triangle ABC is 22.8 units
Answer:
The perimeter of triangle ABC = 22.78 units
Step-by-step explanation:
Formula:-
The length of line segment with end points (x₁, y₁) and (x₂, y₂) is given by,
Length = √ [(x₂ - x₁)² + (y₂ - y₁)²]
To find the each side of triangle
We have A(-2,2), B(6,2), and C(0,8).
AB = √[(6 - -2)² + (2 - 2)²] = √64 = 8
BC = √[(0 - 6)² + (8 - 2)²] = √(36 + 36) = 8.48
AC = √[(0 - -2)² + (8 - 2)²] = √(4 + 36) = 6.3
To find the perimeter of triangle ABC
Perimeter = AB + BC + AC
= 8 + 8.48 + 6.3 = 22.78 units
