Answer:
The values of 'x' they make the statement true are;
B; x = 8
E; x = 125
Step-by-step explanation:
The given criteria for 'x' = "The square root of x is a number that is non-terminating and non-repeating"
The terms non-terminating and non-repeating numbers are used to describe the characteristics of the decimal part of numbers
A non-terminating number is a form of decimal number that has an infinite number of digits out of which no part is endlessly repeating. This type of decimals are part of irrational numbers that cannot be presented in a fraction format
From the options, we have;
A: x = 1, √x = √1 = 1 No fraction, 1 ∉ x
B: x = 8, √x = √8 = 2·√2 Is non-repeating, non-terminating, 8 ∈ x
C: x = 25, √x = √25 = 5 No fraction, 25 ∉ x
D; x = 81, √x = √(81) = 9 ∉ x
E; x = 125, √125 = 5·√5 Is non-repeating, non-terminating, 125 ∈ x.

The altitude of a plane is 1200 meters. From a point on the ground, the angle of elevation of an airplane is 25º. What is the distance from point P to the airplane, to the nearest tenth of a meter? Explain your answer.
Answer:
2839.4 meters
Step-by-step explanation:
Given that:
Altitude = 1200 m
Using trigonometry :
The distance from point P to the airplane :
Using trigonometric relation :
Sin θ = opposite / hypotenus
Sin θ = altitude / x
Sin θ = 1200 m / x
Sin 25 = 1200 / x
0.4226182 = 1200 / x
x = 1200 / 0.4226182
x = 2839.4423
Distance from P to airplane = 2839.4 meters

I AM RIGHT
m is equal to n, there is only one vertical asymptote and -y = –1 is the horizontal asymptote are correct. Therefore, the correct option is option B,C,D.
What is mathematical function?A function in mathematics from such a set X to either a set Y allocates precisely 1 element of Y to every element of X. The sets X and Y are collectively referred to as the function's domain and codomain, respectively. Initially, functions represented the idealized relationship between two changing quantities.
A planet's position, for instance, depends on time. In the past, the idea was developed with both the infinitesimal calculus toward the conclusion of the seventeenth century, as well as the functions that were taken into consideration were differentiable until the 19th century. Just at end of the 18th century, set theory was used to formalize the idea of a function. m is equal to n, there is only one vertical asymptote and -y = –1 is the horizontal asymptote are correct.
Therefore, the correct option is option B,C,D.

In October sally drove 560 miles in her car.
the car travelled 34.5 miles for each gallon of petrol used
Petrol cost £1.08 per litre.
1 gallon = 4.55 litres.
Work out the cost of the petrol the car used in October
The cost of petrol the car used in October is;
Amount spent on fuel in October = £79.76
Distance sally drove in October = 560 miles
She used 1 gallon of petrol for every 34.5 miles she drove.
Thus, number of gallons of petrol she used for the month of October on the car = 560/34.5 gallons
Now, we are told that;
1 gallon = 4.55 litres
Thus; 560/34.5 gallons = (560/34.5) × 4.55/1
Quantity of petrol she used for the month in liters = 73.855 litres
Petrol costs £1.08 per liter.
Thus;
Amount spent on fuel in October = 1.08 × 73.855
Amount spent on fuel in October = £79.7634 ≈ £79.76

The equation for f(x) is
The equation for g(x) is
Answer: f(7) = -128
g(7) = 26
Equation of f(x): f(x)= -11x-51
Equation of g(x): g(x)=3x+5
Step-by-step explanation:
Rate of change of a function: [tex]\dfrac{f(x_2)-f(x_1)}{x_2-x_1}[/tex]
From the table. Rate of change in f(x)= [tex]\dfrac{f(1)-f(0)}{1-0}=\dfrac{-62+51}{1}=-11[/tex]
Rate of change in g(x)= [tex]\dfrac{g(1)-g(0)}{1-0}=\dfrac{8-5}{1}=3[/tex]
Also, the rate of change throughout the function is the same, hence both are linear functions.
Equation of linear function: [tex]f(x)=mx+c[/tex], where m= rate of change of function, c = f(x) at x=0.
From table, f(0)= -51 , g(0)=5
Equation of f(x): f(x)= -11x-51
Equation of g(x): g(x)=3x+5
f(7) = -11(7)-51 = -77-51 = -128
g(7) = 3(7)+5 = 21+5 = 26
f(7) = -128
g(7) = 26

Answer:
2/7 is the scale factor.
Step-by-step explanation:
All you have to do is get two sides that are equal to each other. Let's say Side SR and YX. 3 and 10.5. Do 3/10.5, which is 30/105, which simplified is 6/21, which again simplified is 2/7. So, the scale factor is 2/7.

Answer: D
Step-by-step explanation:
Since a tadpole becomes a frog as it ages, it makes sense that the axis of the tail would go down as it ages since frogs don’t have tails. If you see the x axis as the tempature, and the coats as the y axis. It would make sense that as the tempature gets colder, more people would be buying coats. But basically, D is the only one that doesn’t have a cause and affect, so it wouldn’t have a very linear scatter plot. For example, I have the same letters in my name as someone I know who is 6‘ 4”, and I’m only 4’ 8”. So D wouldn’t make such a nicely formed scatter plot.

Cendrick D'Amitrano works Friday and Saturday delivering pizza. He delivers 8 pizzas on Friday. How many pizzas must he deliver on Saturday to average (mean) 11 pizzas per day?
Answer:
Number of pizza deliver on Saturday = 14 pizza
Step-by-step explanation:
Given:
Number of delivery day (Friday, Saturday) = 2
Number of pizza deliver on Friday = 8
Average of delivery (Mean) = 11 pizza
Find:
Number of pizza deliver on Saturday
Computation:
Mean = Sum of pizza / Number of delivery day
11 = [8 + Number of pizza deliver on Saturday] / 2
22 = 8 + Number of pizza deliver on Saturday
Number of pizza deliver on Saturday = 22 - 8
Number of pizza deliver on Saturday = 14 pizza

Paulette wrote the equation below to show f, the amount of framing she needs for a square frame with a side length of s centimeters. f=4s How many centimeters of framing does Paulette need for a square frame that has a side length of 15.3 centimeters. Pls help this is a test A. 61.2 centimeters B. 60.3 centimeters D. 19.3 centimeters C. 11.3 centimeters
Answer: 61.2 centimeters
Step-by-step explanation:
Since the equation given to show the amount of framing that she needs for a square frame with a side length of s centimeters is:
f = 4s
Therefore, the number of centimeters of framing needed by Paulette for a square frame that has a side length of 15.3 centimeters will be:
f = 4s
f = 4 × 15.3
f = 61.2 centimeters
London in column bought 1/2 pound of peanuts they are sharing the nuts equally how many pounds of nuts do each person get
Answer: 1/4 pounds
Step-by-step explanation:
Full question is:
Landon and Colin bought a 1/2 pound of peanuts. They are sharing the nuts equally. How many pounds of peanuts will each person get?
There are 2 people here - London and Colin - and they are to share 1/2 pounds of nuts equally amongst themselves.
They should therefore divide the nuts in 2:
= Amount of nuts / Number of people
= 1/2 ÷ 2
= 1/2 * 1/2
= 1/4 pounds
Note: When dividing a fraction, multiply the inverse of the divisor.
