Using Pythagoras's theorem, the set of measurement that can be used to form a right triangle is √2, √7 and 9.
How to find the sides of a right triangle?A right angle triangle is a triangle that has one of its angles as 90 degrees.
The sides of a right angle triangle can be found using Pythagoras's theorem.
Therefore, Pythagoras's theorem is described as follows;
c² = a² + b²
where
a and b are the legs of the right trianglec is the hypotenuse of the right triangle.Therefore, the sides of the triangle that can be used to form a right triangle will have to obey the Pythagoras's theorem,
(√2)² + (√7)² = 9
2 + 7 = 9
Therefore, the last option can form a right triangle.

Tom’s car has 11 1/9 gallons of gas. If he uses 38 of the gas, how much gas does the car have left?
Answer: 6 [tex]\frac{17}{18}[/tex] gallons of gas left in the car
Step-by-step explanation:
Upon further clarification, this question reads "3/8 of the gas" and not "38 of the gas."
If Tom's car has 11 1/9 gallons of gas, and we want to know how much gas the car will have left if he uses 3/8 of that, we first need to find 3/8 of 11 1/9.
"Of" can usually be written as multiplication.
3/8 of 11 1/9 = 3/8 * 11 1/9 = 4 1/6
Next, we will use subtraction since he uses 4 1/6 gallons of gas.
11 1/9 - 4 1/6 = 6 17/18 gallons
4. the probability that an engine overheats is 0.12. the probability that an engine leaks oil is .08. (a) if overheating and leaking oil are independent, what is the probability that an engine overheats and leaks oil?
The probability that the engine over heats and leaks is 0.0096
The probability is computed by dividing the total number of possible outcomes by the number of possible ways the event could occur. Probability and odds are two distinct ideas. Odds are calculated by dividing the likelihood of an event by the likelihood that it won't.
Probability is a metric used to express the possibility or chance that a particular event will occur. Probabilities can be expressed as fractions from 0 to 1, as well as percentages from 0% to 100%.
Engine leaks oil AND overheats,
hence P(Engine overheats) = P(Engine overheats) X P(Engine leaks oil) = 0.12 X 0.08 = 0.0096
Hence the probability of leaking of engine due to over heating is 0.0096

Based on the quantity of the bag of sugar that Jaleel and Angela purchased, and their recipes for brownies, the amount of flour needed by each is:
Angela - 5 cups of flour Jaleel - 6 ²/₃ cups of flourHow much flour is needed?Jaleel and Angela purchased a 20-cup bag of sugar and divided it evenly which means that they each get 10 cups of sugar.
Jaleel's recipe shows that every 1.5 cups of sugar needs a cup of flour. If he had 10 cups of sugar therefore, the amount of flour needed would be:
= Number of cups of sugar / Cups of sugar per cup of flour
= 10 / 1.5
= 6 ²/₃ cups of flour

Bethany is building a storage trunk. 5ft long, 4ft height and 2ft wide. how much wood is needed to make the trunk
Answer:
76 square feet of wood.
Explanation:
Bethany is building a storage trunk with the following dimensions:
• Length = 5 ft.
,• Height = 4 ft.
,• Width = 2 ft.
We are to determine how much wood is needed to make the trunk.
The amount of wood that will be needed to make the truck is the surface area of the trunk. The storage trunk is in the shape of a rectangular prism.
The surface area of a rectangular prism is found using the formula below:
[tex]\text{Surface Area=2(LW+LH+WH)}[/tex]Substitute the given dimensions:
[tex]\begin{gathered} \text{Surface Area}=2(5\times2+5\times4+2\times4) \\ =2(10+20+8) \\ =2\times38 \\ =76\; ft^2 \end{gathered}[/tex]Bethany needs 76 square feet of wood to make the trunk.
If sin A 0.3, cos A = 0.7, sin B = (1/√5)
and cos B: (-1/√5) find the exact value of cos(A - B).
(i know the answer but i want to know how to solve it as well)
The exact value of cos(A - B) is -2√5 /25.
What are Sine and Cosine?In math, the trigonometric functions of an angle are sine and cosine. In the context of a right triangle, the sine and cosine of an acute angle are defined as the ratio of the lengths of the adjacent leg to the hypotenuse, and the sine of the specified angle is the ratio of the opposite leg's length to the hypotenuse's length.The concepts of sine and cosine can be expanded to include any real value in terms of the lengths of particular line segments in a unit circle.The sine and cosine can be extended to any positive or negative value, even complex numbers, according to more recent definitions of the terms, which also represent them as infinite series or as the solutions to specific differential equations.Therefore,
sin A = 0.3
sin B = (1/√5)
cos A = 0.7
cos B = (-1/√5)
cos(A-B) = cos a cos b + sin a sin b
⇒ cos(A-B) = 0.7(-1/√5) + 0.3((1/√5))
⇒ cos(A-B) = -0.7/√5 + 0.3/√5
⇒ cos(A-B) = -0.4/√5
On multiplying, √5 on the numerator and denominator,
⇒ cos(A-B) = -0.4 x √5 / 5
⇒ cos(A-B) = -2√5 /25

Final Answer
Hence , it is false
Answer:
False
Step-by-step explanation:
Definition:
Function is a set of coordinate points where each coordinate points do not have same domains (x-values). If we express mathematically, we can do as [tex]\displaystyle{f=\left \{(x_0,y_0),(x_1,y_1),(x_2,y_2),...,(x_n,y_n)\}\right}[/tex] where [tex]\displaystyle{x_0\neq x_1 \neq x_2\neq \dots \neq x_n}[/tex]Function is also considered to be a relation but not all relations can be functions.
As accorded to the relation, it turns out that there are two same domains (x-values) which is 9 from (9,1) and (9,-3). Therefore, this relation doesn’t satisfy the definition of function so it’s not a function.

The value of x in the triangle is 3.
How to find the angles in a triangle?The exterior angle of the triangle is VBC.
Using the exterior angle theorem, the value of x can be found in the triangle.
The exterior angle theorem states that the measure of an exterior angle of a triangle is greater than either of the measures of the remote interior angles.
In other words, an exterior angle of a triangle is equal to the sum of the two opposite interior angles.
Therefore,
m∠D = 9x - 2
m∠C = 40°
m∠VBC = 20x + 5
Hence,
20x + 5 = 9x - 2 + 40
20x + 5 = 9x + 38
20x - 9x = 38 - 5
11x = 33
x = 33 / 11
x = 3
Therefore,
x = 3

it is known that a certain kind of algae in the dead sea can double in population every 4 days. suppose that the population of algae grows exponentially, beginning now with a population of 3,000,000. (a) how long it will take for the population to quadruple in size? days (b) how long it will take for the population to triple in size? days
Since the algae grow exponentially with doubling time of 4 days, then the population will be quadruple in size in 8 days and will be triple in size in 6.34 days.
The easiest way is to consider the situation as a geometric sequence. If the population doubles its size in 4 days, then it will be quadruple in:
2 x 4 days = 8 days.
In general, we can use the growth formula:
P(t) = Po . 2^(t/Td)
Where:
P(t) = population at time t
Po = initial population
Td = doubling time
Parameters given:
Td = 4 days
P(t) = 3Po
Plug those parameters into the formula:

We have been given the required line that passes through the point (-8,6) and has a slope of 1/4.
What is the slope of the line?The slope of a line is defined as the angle of the line. It is denoted by m
Slope m = (y₂ - y₁)/(x₂ -x₁ )
Let the required line would be as
⇒ y - y₁ = m (x - x₁ )
The required line passes through the point (-8,6)
Here x₁ = -8 and y₁ = 6 and m = 1/4
Substituting these inputs into the above equation obtains the line equation.
⇒ y - 6 = 1/4 (x - (-8))
⇒ y - 6 = 1/4 (x + 8)
⇒ 4y - 24 = x + 8
