Answer:
y=179
Step-by-step explanation:
the statement is true.
you need to replace (x) for 4 and solve
y= 40(4) + 19
y=160 + 19
y=179
it costs 179$ for 4 weeks so the statement is true
A rectangle has an area of 266 square centimeters. If it's length is 19 cm, find its width
Answer: w=14 cm

A map of a playground can be represented on the coordinate plane below. The swings are located at (5, 7), the slide is located at (2, –4), and the sandbox is located at (0, 5). Jenny left the swings and walked 3 yards west and 2 yards south. Kent left the sandbox and walked 5 yards east and 4 yards north. If each square of the coordinate plane is equal to one square yard, how many yards north of the swings is Kent located? Help PLS
Answer:
2 yards
Step-by-step explanation:
The coordinates of the location of the swings = (5, 7)
The coordinates of the location of the slides = (2, -4)
The coordinates of the location of the sandbox = (0, 5)
The path through which Jenny walked = 3 yards west and 2 yards south from the swing
The path through which Kent walked = 5 yards east and 4 yards north from the sandbox
The coordinates of Kent's final location = (0 + 5, 5 + 4) = (5, 9)
Given that the coordinate of the location of the swing = (5, 7)
Kent is located at the coordinate (5 - 5, 9 - 7) = (0, 2) relative to the swing
Therefore, Kent is located 2 yards north of the swing.
Solve this system of equations. Explain how you determined your answer.
2x−4y=−14
−8x+4y=−4
Answer:
(3, 5 )
Step-by-step explanation:
Given the 2 equations
2x - 4y = - 14 → (1)
- 8x + 4y = - 4 → (2)
Adding (1) and (2) term by term will eliminate the y- term
- 6x + 0 = - 18
- 6x = - 18 ( divide both sides by - 6 )
x = 3
Substitute x = 3 into either of the 2 equations and solve for y
Substituting into (2)
- 8(3) + 4y = - 4
- 24 + 4y = - 4 ( add 24 to both sides )
4y = 20 ( divide both sides by 4 )
y = 5
solution is (3, 5 )

The linear equations would be
4x + 5y = 62 (the equation representing the total cost of Kent)
6x + 2y = 60 (the equation representing the total cost of Rew)
and the solution would be x = 8, y = 6.
What is a system of linear equations?
A system of linear equations is a set of two or more linear equations that describe a relationship between multiple variables. The variables in each equation are related to each other, and the solution of a system of linear equations is the set of values that satisfy all of the equations in the system.
In this case, since Kent and Rew each bought the same amount of boondins and hopts, we can use the same variable names (x for boondins and y for hopts) for both of them. We can use this information to write two equations to model the relationship between the amounts of boondins and hopts that Kent and Rew bought:
4x + 5y = 62 (the equation representing the total cost of Kent)
6x + 2y = 60 (the equation representing the total cost of Rew)
This system of linear equations is called a system of two equations in two variables.
Hence, the linear equations would be
4x + 5y = 62 (the equation representing the total cost of Kent)
6x + 2y = 60 (the equation representing the total cost of Rew)
and the solution would be x = 8, y = 6.

The upper bound of a is 3.13.
Upper Bound
The smallest amount that would round up to the following anticipated value is the upper bound.
Significant FiguresThe number of digits that contribute to a value's level of precision is known as significant figures and is typically found in measurements. As soon as a digit is non-zero, we begin calculating significant numbers.
Given in the question
v = 37. 6
u = 11. 3
t = 8. 4
To find:- a = (v - u)/t
Solution: -
Since finding the upper boundary for a
Upper boundary = (upper v - lower u) / (lowest t)
So putting the value values of v, u, t in we get the value
a = (37.6 - 11.3) / 8.4
Therefore the value of a = 3.13

The equation of the linear function after a translation down 9 units is given as follows:

How to define the linear function?The slope-intercept definition of a linear function is given as follows:
y = mx + b.
In which:
m is the slope, representing the rate of change of the output variable relative to the input variable.b is the y-intercept, representing the value of y at which the graph cross the y-axis.The graph of the function crosses the y-axis at y = -2, hence the intercept b is given as follows:
b = -2.
When x increases by 2 units, from x = 0 to x = 2, y increases by 2 units, from y = -2 to y = 0, hence the slope is calculated as follows:
m = 2/2.
Then the function is of:
y = x - 2.
After the translation down 9 units, 9 is subtracted from the function, hence:
f(x) = x - 2 - 9
f(x) = x - 11.

Hence option (B) is a correct choice and rest all other options are incorrect
1/b^2 ∑ (-1)^k(t^2/b^2)^k
Step-by-step explanation:
Remember that the sum of infinite GP is given by the formula blow:
First term=a
Common ratio=r
S=a/1 - r
Wherever the common ratio r falls within the interval (-1,1)
When the given series is compared to the infinite sum:
First term=a
Common ratio=r
S= a/1-r = 1/b^2+t^2
Now given: |t| < |b|=0<t^2/b^2<1
S=1/B^2.1/1-(-T^2/B^2)
=A=1
R=-T^2/B^2
Writing the general form:

For the described situation, y = 6sin ( (π / 10) x ) - 10 is the sine function.
What is the sine function?The trigonometric functions in mathematics are real functions that connect the right-angled triangle's angle to the ratios of its two side lengths.
They are extensively employed in all fields of geometry-related study, including geodesy, solid mechanics, celestial mechanics, and many others.
Asin(Bx)+C is the usual sine function formula.
A buoy bobs 6 meters up and down.
That is, the amplitude of the buoy shifts by 6 meters both vertically and horizontally.
A=6 Amplitude
The x-axis distance that constitutes one complete oscillation is known as the period.
We are aware that it takes a buoy 10 seconds to go from its greatest position to its lowest point (half oscillation).
20 seconds make up the complete oscillation period.
⇒ 20 (B) = 2π
B=2π /20
= π/ 10
Given that the buoy is 10 meters under the ocean's surface, C equals –10.
Using the formula's whole range of values:
⇒y = 6sin ( (π/ 10) x ) - 10
The midline is the initial point.
x=0 is the first point.
⇒y=6sin(0)-10
y= -10
The line is drawn from the origin at y = -10.
Either the highest or smallest value is at the second point.
Therefore, (5,-4) and (15, -16.)
Therefore, for the described situation, y = 6sin ( (π / 10) x ) - 10 is the sine function.

We only have one side, DB, so we have to use the given angles rather than the Pythagorean theorem.
Answer:
BC ≈ 205.8 ft
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos71° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{BD}{BC}[/tex] = [tex]\frac{67}{BC}[/tex] ( multiply both sides by BC )

Solve this expression as;
⇒ 37ˣ = 12
Taking log both side, we get;
⇒ log 37ˣ = log 12
⇒ x log 37 = log 12
⇒ x = log 12 / log 37
⇒ x = 1.08 / 1.57
