30. Find the value of expression 20m2 + 30m + 40 when a)m = -3 b)m= - 4 c) m = 3
Answer:
di you mean m² when you say m2 or not?
The values of the expression are;
-21, 240, 310 respectively
We were given the equation as ;
20 [tex]m^{2}[/tex] + 30m + 40
Then we can find the values of the expression with the given options to know the answer by input the value of ' m' into the given equation
Option (a) (m=-3)20( [tex]-3^{2}[/tex] )+ 30(-3)+ 40 = -21Option (b) (m=-4)20([tex]-4^{2}[/tex] )+ 30(-4)+ 40 = 240Option (c) (m=3)20([tex]3^{2}[/tex]) + 30(3)+ 40 = 310Therefore, the values of the expression are; -21, 240, 310 respectively

A point moves in the plane of two perpendicular lines so that the product of its distances from the lines always is 12 when the point is 4 units from one of the lines, its distance from that line is decreasing at the rate of 2 units/min. At what rate is the distance from the other line changing at that moment?
I'm not sure how this situation would look so if someone could draw or make a diagram/graph for me (on Desmos or something), I would really appreciate it!
The rate is the distance from the other line changing at that moment will be negative 1.5 units per minute.
What is differentiation?The rate of change of a function with respect to the variable is called differentiation. It can be increasing or decrease.
A point moves in the plane of two opposite lines so the result of its good ways from the lines forever is 12 when the fact of the matter is 4 units from one of the lines, its separation from that line is diminishing at the pace of 2 units/min.
Let the coordinate of the pointe be (x, y). Then the function is given as,
[√(x- 0)²] [√(y - 0)²] = 12
[√x²] [√y²] = 12
x y = 12
At x = 4, the value of the variable 'y' is given as,
4y = 12
y = 3
Differentiate the function with respect to time, then we have
xy' + yx' = 0
4 × y' + 3 × 2 = 0
y' = - 6 / 4
y' = - 1.5 units per minute
The rate is the distance from the other line changing at that moment will be negative 1.5 units per minute.

Write the equation of the line in Slope-Intercept form given the following information: The new line is PARALLEL to y = 3x - 5 The new lines goes through the point (-2, 6).
Answer:
y = 3x + 12
Step-by-step explanation:
y = 3x - 5 (y = 3x +b)
Parallel lines have same slope.
m = 3; (-2 , 6)
y - y1 = m(x -x1)
y - 6 = 3(x -[-2])
y -6 = 3(x + 2)
y - 6 = 3x + 6
y = 3x + 6 + 6
y = 3x + 12

2. Classify the angle as acute, obtuse, right or straight.
O acute
O obtuse
Oright
straight
HELP ASAP
Answer:
Please include the details of the angle
Step-by-step explanation:
When the angle is 93 degrees, the the angle is a obtuse angle. option B is correct.
Given that the measure of angle A is 93 degrees, we can classify the angle as follows:
Angle A = 93 degrees
We know that if angle is less than 90 degrees, it is acute.
if angle is greater than 90 degrees, it is obtuse.
if angle is equal to 90 degrees, it is right angle.
Since the angle measures greater than 90 degrees, it falls within the range of an obtuse angle.
Therefore, the correct classification for angle A is obtuse.

Carlos jogged 5 laps around the school track in 8 minutes. What was his average speed in laps per minute? lap(s) per minute PLEASE I NEED ANSWER I WILL GIVE BRAINYLIST
Answer:
To solve this problem, you would create two ratios and make them equal to each other, both representing laps:minute or laps/minute! With that being said, laps will be in the numerator, or on top, and minutes will be in the denominator, or the bottom! The first ratio, which we know from the problem, will be 5/8. In order to write the second ratio, we need to come up with something to put in place for what we're solving for. I like to use x. So, we need to find how many laps (x) are run in 1 minute. Remember, laps are on top and minutes are on the bottom. The second ratio would look like x/1. Then we make them equal to each other -> 5/8=x/1. You would then solve this equation by multiplying the right side of the equation by the reciprocal of the denominator! So, it would be 1/1(5/8)=x. Because then multiple the numerators and the denominators -> 1(5)=5 and 1(8)=8! This makes the equation turn into x=5/8! Because x equals the number of laps run in one minute, we can say that Ricky ran 5/8 of a lap in one minute or 0.625 laps in one minute!

multiply both sides by 2

If x = 9 units, y = 3 units, and h = 7 units, find the area of the rhombus shown above using decomposition. A. 21 square units B. 13 square units C. 72 square units D. 63 square units
Answer:
63 square units
Step-by-step explanation:
Area of the rhombus = Base × Height
Given
Base = x = 9unit
Height = h = 7units
Substitute into the formula
Area of the rhombus = 9×7
Area = 63units²
Hence the required area of the rhombus is 63 square units

Simplify: ( x² − 3) ( x + 2) + 6 *
Answer:
x(x + 3)(x - 1)
Step by Step :::
= (x² - 3)(x + 2) + 6
= x(x² - 3) + 2(x² - 3) + 6
= x³ - 3x + 2x² - 6 + 6
= x³ + 2x² - 3x
= x(x² + 2x - 3)
= x(x² + 3x - x - 3)
= x{x(x + 3) - 1(x + 3)}
= x(x + 3)(x - 1)
