Answer:
No, the given set of pairs does not represent a function
Step-by-step explanation:
For a set of values to be a function, each input must have one and only one output value
Now, for the given set, we can note that:
The input -13 has two output values; 4 and 9
Therefore, this set is not a function

Given a set of attributes, can you make one triangle, no triangles, or many triangles?
jo says, "the attributes of my triangle are sides that are 3cm and 9cm long. I can make only one triangle because I have to connect the ends of my two sides."
do you agree or disagree? why?
Answer:
All you have to do is use the Triangle Inequality Theorem, which states that the sum of two side lengths of a triangle is always greater than the third side. If this is true for all three combinations of added side lengths, then you will have a triangle.

segments EA and DG
Step-by-step explanation:
A diameter is when a line segment crosses the center of the circle and its endpoints lie on the circle. Both segments EA and DG satisfy the definition of a diameter.
Answer:
EA and DG
Step-by-step explanation:
For it to be a diameter, it has to pass through the center (point H) and touch both sides of the circle.
The ones that work for that are EA and DG

factor the expression using the GCF 6x+24
Answer:
6(x+4)
Step-by-step explanation:
The GCF is 6 thus factor the expression
The given expression 6x + 24 can be factored using the GCF as 6(x + 4).
What is the Factorization?Factorization, also known as factoring, is the breakdown of one element into a product of other objects, or factors, which when multiplied together generate the original. For example, the number 21 factors into primes as 3 × 7, and the polynomial x² − 9 factors as (x+3)(x-3).
The expression is given in the question as:
6x + 24
The expression 6x + 24 can be factored using the greatest common factor (GCF) as follows:
⇒ 6x + 24 = (6x + 24) / 6 × 6
The GCF of 6x + 24 is 6, so we can divide both terms by 6 to get:
⇒ 6x + 24 = (x + 4) × 6
We can then factor out the common factor of 6 to get:
⇒ 6x + 24 = 6(x + 4)
Thus, the given expression 6x + 24 can be factored using the GCF as 6(x + 4).

For positive acute angles A and B, it is know that tan A= 8/15 and sin B= 11/61. Find the value of cos (a+b) in simplest form
Answer:
812/1037
Step-by-step explanation:
To solve this, we have to use trigonometric identities.
Cos (A + B) is given as Cos A Cos B - Sin A Sin B. And from the question, we have that
Tan A = 8/15.
We know that in a triangle, the Tan angle is represented Opp/Adj and thus the Opp is 8, and the Adj is 15. Using Pythagoras, we have
hyp² = opp² + adj²
hyp² = 8² + 15²
hyp² = 64 + 225
hyp² = 289
hyp = √289 = 17
The identity of Cos is Adj/Hyp and that of Sin is Opp/Hyp.
Cos A = 15/17
Sin A = 8/17
Repeating the same process for B, we have
Sin B = 11/61
adj² = hyp² - opp²
adj² = 61² - 11²
adj² = 3721 - 121
adj² = 3600
adj = √3600 = 60
Cos B = 60/61
Now, using the earlier stated trigonometric identity, we have
cos (a + b) = CosA CosB - SinA SinB
cos (a + b) = 15/17 * 60/61 - 8/17 * 11/61
cos (a + b) = 900/1037 - 88/1037
cos (a + b) = 812/1037
Which operation will isolate the variable?
17b = 54 :
addition
subtraction
multiplication
division
Answer:
Division
Step-by-step explanation:
here's your process
=>. it is your equation 17b = 54
=> now divide 17 on both side
=> then we get 17b/17 = 54/17
=> hence , we get b = 54/17
=>now b is isolated by the method of division

A water tank contains exactly 1,000 gallons. A pump fills the remainder of the tank using
a logistic function. If the volume of the tank is 15,000 gallons and the pump fills the tank at a rate of 10.4% per minute, explain how to find the value of a for the logistic function that describes this scenario.
Answer: V ( t ) = 1 + 1 4 e − 0 . 1 0 4 t 1 5 , 0 0 0
The required value for the logistic function describing the scenario of the water tank being filled at a rate of 10.4% per minute.
What is the logistic function?The logistic function has the form:
[tex]f(x) = L / (1 + a \times e^{(-kx)})[/tex]
Where:
f(x) is the volume of the tank at time x
L is the maximum volume the tank can hold
a is a constant that determines the growth rate of the function
k is a constant that determines the rate at which the growth slows down as the tank approaches the maximum volume
In this case, the maximum volume of the tank is 15,000 gallons, so L = 15,000.
The pump fills the tank at a rate of 10.4% per minute, so k = 0.104.
To find the value of a, we need to solve the logistic equation for a given the values of f(x), L, and k.
We can rearrange the logistic equation to solve for a:
[tex]a = (1 / f(x)) - (1 / L) \times e^{(kx)}[/tex]
Substituting the known values into this equation, we get:
[tex]a = (1 / 1,000) - (1 / 15,000) \times e^{(0.104x)}[/tex]
This equation can be used to solve for the value of a for any given value of x (time). For example, if we want to know the value of an after 10 minutes, we can substitute x = 10 into the equation to get:
[tex]a = (1 / 1,000) - (1 / 15,000) \times e^{(1.04)}[/tex]
This gives us the value of a for the logistic function that describes the scenario of the water tank being filled at a rate of 10.4% per minute.

Answer:
Area of circle: 1662.57 cm
Circumference of circle: 144.57 cm
Step-by-step explanation:
Formula of area of circle:
pi x r2 or radius x radius
So, it's 22/7 x 23 x 23 = 1662.571429
Formula of circumference of circle:
2 x pi x radius OR
pi x diameter
Let's use the second method, to find diameter it is radius x 2 = 46
So,
46 x 22/7 = 144.5714286
On Friday, Carlotta had 6/8 of her paper left to write. She wrote 2/6 of the paper on Saturday and ¼ of the paper on Sunday. At the end of the weekend, what fraction of her paper does Carlotta have left to write?
Answer:
[tex]\frac{1}{6}[/tex]
Step-by-step explanation:
Skills needed: Fraction Subtraction, Least Common Denominator (LCD)
1) [tex]\frac{6}{8} - \frac{2}{6} - \frac{1}{4}[/tex] is the operation you would do.
--> You would do this because, Carlotta has [tex]\frac{6}{8}[/tex] of the paper left, and does one fraction amount ([tex]\frac{2}{6}[/tex]) on Saturday & does another fraction amount ([tex]\frac{1}{4}[/tex]) on Sunday.
--> Using subtraction is the best way
2) Now, we need to figure out the Least Common Denominator for all 3 fractions.
8,6,4 are the denominators.
The lowest number that is a factor of all them is 24.
So, it would then become [tex]\frac{18}{24} - \frac{8}{24} - \frac{6}{24}[/tex]
This would become: [tex]\frac{18-8-6}{24}[/tex] (18-8-6 = 4)
So then: [tex]\frac{4}{24}[/tex] is your answer.
This simplifies into [tex]\frac{1}{6}[/tex].

Jonathan was 45 inches tall when he started kindergarten. He grew an average of 2.5 inches every year. Jonathan is now 62.5 inches tall. Which equation can be used to find how many years ago Jonathan started kindergarten, and how many years ago was it?
A. (45 + 62.5) ÷ 2.5 = x 7 years
B. 2.5x + 45 = 62.5 7 years
C. (45 + 62.5) ÷ 2.5 = x 43 years
D. 2.5x + 45 = 62.5 43 years
Answer:
B; 2.5x + 45 = 62.5
Step-by-step explanation:
Since the current height is 62.5, and the starting height is 45, then all you have to do is subtract 45 from 62.5, then divide that by 2.5 to get your answer, which should be 7 years.
