Answer:
Positive Slope-A positive slope means that two variables are positively related—that is, when x increases, so does y, and when x decreases, y decreases also. Graphically, a positive slope means that as a line on the line graph moves from left to right, the line rises. Another words, the line goes up.
Negative Slope-A line with a negative slope is a line that is trending downward from left to right. In other words, the line's rise to run ratio is a negative value. Or the line goes down
Undefined Slope- An undefined slope is the slope of a vertical line! The x-coordinate never changes no matter what the y-coordinate is.
Zero Slope-A zero slope is just the slope of a horizontal line. The y-coordinate never changes no matter what the x-coordinate is.

We have to determine which relation is a function.
What is the function?
A function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function. Functions were originally the idealization of how a varying quantity depends on another quantity.
The relation between the function is
X cannot repeat itself

If a 40-foot tall ladder is placed 15 feet from the base of a house, how high up the house will the
ladder reach?
Answer:
36.66 ft
Step-by-step explanation: You have to use the pythagorean theorem. a^2 + b^2 = c^2 (if you lean a ladder against a wall, it will make the shape of a triangle) The hypoteneuse would be 40 feet as it is the height of the ladder (the longest side). The one of the legs would be 15 ft (how far it is from the base of the house). You would then just plug the numbers in : a^2 + 15^2 = 40^2
a^2 + 256 = 1600
a^2 = 1344
a = 36.66
What is the value of x in the equation below? 150 = 3/5 x
Answer:
x=250
Step-by-step explanation:
150= 3/5 x
50 = 1/5 x
x=50×5
x=250
Final answer:
To solve the equation 150 = 3/5 x for x, divide both sides by 3/5, which is equivalent to multiplying by its reciprocal (5/3), resulting in x being equal to 250.
Explanation:
To find the value of x in the equation 150 = 3/5 x, you first divide both sides of the equation by 3/5 to isolate x. This can be done by flipping the fraction and multiplying, as the division by a fraction is the same as multiplication by its reciprocal.
The process is as follows:
150 = (3/5) x
150 * (5/3) = x
50 * 5 = x
250 = x
Therefore, the value of x is 250.

In ΔNOP, the measure of ∠P=90°, the measure of ∠N=83°, and NO = 83 feet. Find the length of OP
Answer: Length OP = 82.38 feet
Step-by-step explanation: Given that the ΔNOP, the measure of ∠P=90°, the measure of ∠N=83°, and NO = 83 feet.
We can find the length of OP by using trigonometry ratio since it is a right angle
NO = hypothenus and
OP = opposite
Sin 83 = OP/NO
Sin83 = OP/83
OP = 83sin83
OP = 82.38 feet

A person invest $1800 in a account that earns 2.46% annual interest. Find when the value of the investment teachers $3500
Answer:
28 years
Step-by-step explanation:
To find the number of years that the investment will reach $3500, we can use the formula of compound interest:
P = Po * (1+r)^t
where P is the final value, Po is the inicial value, r is the annual interest and t is the time in years.
In this question, P = 3500, Po = 1800 and r = 2.46% = 0.0246, so:
3500 = 1800 * (1+0.0246)^t
1.0246^t = 3500/1800
1.0246^t = 1.9444
Using logarithm in both sides:
log(1.0246^t) = log(1.9444)
t*log(1.0246) = 0.2888
t * 0.0106 = 0.2888
t = 0.2888 / 0.0106 = 27.2453 years
So the investment will reach $3500 after 28 years (rounding the result up, because after 27 years the investment will not reach $3500)
This equation shows how the number of chocolates Josie has left is related to the number of gift baskets she assembles.
c = –9g + 97
The variable g represents the number of gift baskets she assembles, and the variable c represents the number of chocolates she has left. Up to how many gift baskets can Josie assemble and still have 16 chocolates left?
Josie can assemble 9 gift baskets
From the question, we are to determine up to how many gift baskets Josie can assemble and still have 16 chocolates left
To do this,
Simply substitute c = 16 in the equation and solve for g
The given equation is:
c = –9g + 97
Substitute c= 16:
c = –9g + 97
16 = -9g + 97
9g = 97 - 16
9g = 81
Divide both sides by 9:
g = 81/9
g = 9

Answer:
70 doses.
Step-by-step explanation:
First, you have to find how many bottles 7/3 is.
Simplify 7/3 to 6/3 + 1/3.
6/3 simplifies to 2, which leaves us with 2 and 1/3.
30 multiplied by 2 and 1/3 is equal to 70.

What is the value of x in the figure? Enter your answer in the box. X=
Answer:
x = 34
Step-by-step explanation:
The two angles sum to a right angle, which is 90 degrees. We can tell this from the box in the corner
x+56 = 90
Subtract 56 from each side
x+56-56= 90-56
X = 34
Answer:
x=34
Step-by-step explanation:
The angles are complementary, or they add to 90 degrees. We know this because of the little rectangle in the corner.
x+56=90
Subtract 56 from both sides
x+56-56=90-56
x=34

We have a cone here conjoined to a semi-sphere.
so
Cone volume: C = (1/3)*(πr^2) * h
semi-sphere volume : V = (1/2)* (4/3) * (π * r^3)
r = 3 mm and h = 5mm
so C = (1/3)*(π (3)^2) * 5 = 15π cubic mm
V = (1/2)* (4/3) * (π * 3^3) = 18 π cubic mm
Total Volume = 15π + 18 π= 33π cubic mm

In how many ways is it possible for 15 students to arrange themselves among 15 seats in the front row of an auditorium?
Answer:
225
Step-by-step explanation:
bc 15 times 15 is 225 and thats how you find out how many combos ya square it
Final answer:
The number of ways 15 students can arrange themselves in 15 seats is calculated using permutations and is equal to 15 factorial (15!).
Explanation:
The question involves finding the number of different ways to arrange 15 students in 15 seats, which is a combinatorial problem in mathematics. This problem can be solved by using the concept of permutations. Indeed, if we have 15 distinct objects (students) and we want to arrange them in 15 distinct positions (seats), we need to calculate the number of permutations of 15 items taken 15 at a time.
The formula for the number of permutations of n objects taken r at a time is P(n, r) = n! / (n-r)!, where ! denotes the factorial of a number. For this case, since we are permuting all 15 students (n = 15), the number of ways they can arrange themselves in 15 seats is simply 15! (15 factorial).
To calculate 15 factorial, we multiply all integers from 1 to 15:15! = 15 imes 14 imes 13 imes ... imes 1Therefore, there are 15! different ways for the students to arrange themselves in the front row of an auditorium.Someone Please helpppp!!!

Find the value of x.
m∠IHG = 162°
m∠IHK = (4x + 4)°
m∠KHG = (8x + 2)°
Final answer:
The value of x is 1.
Explanation:
To find the value of x in the given question, we need to set up an equation involving the angles.
From the information given, we have:
m∠IHG = 162°
m∠IHK = (4x + 4)°
m∠KHG = (8x + 2)°
We can set up an equation based on the relationship between the angles:
m∠IHG + m∠IHK + m∠KHG = 180°
Substituting the given angle measures, we have:
162° + (4x + 4)° + (8x + 2)° = 180°
Combine like terms:
12x + 168 = 180
Subtract 168 from both sides:
12x = 12
Divide both sides by 12:
x = 1
Therefore, the value of x is 1.
