Answer:
4
Step-by-step explanation:
slope equation is y2-y1/x2-x1
insert points: -30-(-10)/-2-3
simplify: -30+10/-5
simplify further: -20/-5
negatives cancel because there cannot be both on top, making it positive: 20/5
divide: 20/5=4
[tex]\huge\text{$m=\boxed{4}$}[/tex]
Hey there! Start with the slope formula, where [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] are the two known points.
[tex]\begin{aligned}m&=\dfrac{y_2-y_1}{x_2-x_1}\\&=\frac{-30-(-10)}{-2-3}\end{aligned}[/tex]
Simplify.
[tex]\begin{array}{c|l}\textbf{Solving}&\textbf{Reason}\\\cline{1-2}\\m=\dfrac{-30+10}{-2-3}&x-(-y)=x+y\\\\m=\dfrac{-20}{-5}&\text{Addition and subtraction}\\\\m=\dfrac{20}{5}&\text{The negatives cancel out}\\\\m=\dfrac{4}{1}&\text{Divide the numerator and denominator by $5$}\\\\m=\boxed{4}&\dfrac{x}{1}=x\end{aligned}[/tex]
your friend claims that it is possible to draw a parabola through any two points with different x coordinates. Is your friend correct? explain your answer
9514 1404 393
Answer:
yes
Step-by-step explanation:
In general, a (vertical) parabola can be drawn through any 3 non-collinear points having different x-coordinates. For any given pair of points, there are an infinite number of points that are non-collinear with them.
An infinite number of parabolas can be drawn through two points. Your friend is correct.

The total amount of sap y (in ounces) collected from a tree after x weeks is represented by the equation y = 3x + 8. How much more total sap is there after 5 weeks than after 4 weeks?
3 ounces more sap is there after 5 weeks than after 4 weeks.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Given that, the total amount of sap y (in ounces) collected from a tree after x weeks is represented by the equation y= 3x + 8.
Here, x=4 and x=5 is given
When x=4, we get
y=3(4)+8
= 20
When x=5, we get
y=3(5)+8
= 23
Difference=23-20=3 ounce
Therefore, 3 ounces more sap is there after 5 weeks than after 4 weeks.

In an experiment, the probability that even A occurs is 0.2 and the probability that event B occurs is 0.5. If A and B are independent events, which statement is true?
A.
P(A and B) = 0.1
Answer:
oop
Step-by-step explanation:
The probability of event A and event B will be 0.10. Then the correct option is A.
What is probability?Its fundamental concept is that someone will nearly surely occur. The proportion of positive events in comparison to the total of occurrences.
Then the probability is given as,
P = (Favorable event) / (Total event)
In an experiment, the probability that event A occurs is 0.2 and the probability that event B occurs is 0.5.
If A and B are independent events. Then the probability is given as,
P(A and B) = P(A) x P(B)
P(A and B) = 0.2 x 0.5
P(A and B) = 0.10
The probability of event A and event B will be 0.10. Then the correct option is A.

James completed 18 math problems. This is 30% of the problems he has to do. How many total math problems must he complete to be done?
Answer:
60 = n
Step-by-step explanation:
This problem can be rewritten as:
18 is 30% of what?
% means "out of 100" and of means "multiply"
18 = 30/100 ⋅ n
100/30 ⋅ 18 = 100/30 ⋅30/100 ⋅ n
1800/30 = 100/30 ⋅ 30/100 ⋅ n (both the 30/100 and 100/30 are crossed out here)
60 = n

A child got 16.67/20 on a test. what is their grade in percent form?
Answer:
83.4% or 83%
Step-by-step explanation:
when trying to find a percent, divide the numerator (# of correct answers) by the denominator (# of total questions possible to get correct)
Which would be 16.67 divided by 20 which equals .8335. Move the decimal point over two placements which would be 83.35. I rounded it up to 83.4. If trying to find a whole number not a decimal it would be 84%. Depending on the grading scale, it would be a B.

A helicopter is hovering above a road at an altitude of 24 m. At a certain time, the distance
between the helicopter and a car on the road is 45 m. calculate the angle of depression from
the helicopter from the car. [
Answer: 32.23°
Suppose the setpoint of a helicopter is A and that of a car is C and that of the road is B
The distance from the helicopter to the car and the road forms a right triangle
=> ΔABC is a right triangle at B
=> the angle of depression from the helicopter from the car is ∠ACB
we have: ΔABC is a right triangle => sin ∠ACB = 24/45
=> m∠ACB = 32.23°
