Answer:
A
Step-by-step explanation:
m = Y2 - Y1/ X2 - X1
m= -7 - 5/ 4 - 10
m = -12/ -6
m = 2
y - y1 = m ( x - x1)
y - 5 = 2 (x - 10)
Parabolas in geometry. i need help please
Answer:
OPtion B
Step by step explanation:
Lets plug in a random value for x.
Lets say 5 is x
-8(-5-5)=(y+1)^2
5-5 = 0
-8(0) = 0
0 = (y+1)^2
Square root of both sides
0 = y+1
subtract one from both sides
-1 = y
that means the x is 5 and the y is -1. Option B illustrates exactly that!

Step-by-step explanation:
How is the graph below misleading?
different widths of the bars
too large of increments used
y-axis doesn't begin at zero
broken y-axis
Answer:
A is the right answer
Step-by-step explanation:
the y axis can start at 0 and the y axis isn't broken. and the increments aren't to large so most reasonable will be A
Answer:
different widths of the bars
Step-by-step explanation:
the y-axis does begin at 0, the increments are reasonable, and the y-axis is not broken
the widths of the bars are visibly different, so that answer makes the most sense.
Stacy drew a triangle to explain the relationship between the angles of a triangle and an exterior angle. She labeled the interior angles 1, 2, and 3. She labeled as 4 the exterior angle that is adjacent to angle 2. Triangle with angles labeled 1, 2, 3, & exterior angle at angle 2 is labeled 4. What should Stacy do to explain the relationship between an exterior angle and the interior angles in a triangle?
9514 1404 393
Explanation:
Stacy can write two equations showing the relationships of the angles:
∠1 +∠2 +∠3 = 180° . . . . . . . sum of angles in a triangle
∠2 +∠4 = 180° . . . . . . . . . . angles of a linear pair are supplementary
__
Subtracting the second equation from the first gives ...
(∠1 +∠2 +∠3) -(∠2 +∠4) = (180°) -(180°)
∠1 +∠3 -∠4 = 0
Adding ∠4 to both sides gives the relationship Stacy is looking for:
∠1 +∠3 = ∠4
_____
Alternative approach
Stacy could subtract ∠2 from both equations to give ...
∠1 +∠3 = 180° -∠2
∠4 = 180° -∠2
Then she could equate the two expressions for 180° -∠2:
∠1 +∠3 = ∠4

Are the functions linearly dependent on the interval (0,1)? y1=sintcost,y2=4sin2ty1=sintcost,y2=4sin2t hint: recall that function are linearly dependent on a given interval if one is a constant multiple of the other.
Answer: hello your question is poorly written attached below is the complete question
answer:
since y1 = 1/2 y2 on ( 0,1 ) the function are linearly dependent on ( 0,1 ) ( B )
Step-by-step explanation:
First step : Determine if y1 and y2 are linearly dependent
interval = ( 0,1 )
Functions: y1 = sin t cost t , y2 = 4 sin t
We can verify if these functions are linearly independent or linearly dependent by using the determinate form
attached below is the detailed solution
From the attached solution we can conclude that
y1, y2 is linearly dependent on ( 0,1 )
hence ; since y1 = 1/2 y2 on ( 0,1 ) the function are linearly dependent on ( 0,1 )

Let's use middle term break method to factor this polynomial.
In Quadratic Factorization using Splitting of Middle Term which is x term is the sum of two factors and product equal to last term. Factor each pair by finding common factors.
we nee two number which give 144 wh3n multiplied and 24 when added.So, 12 and 12 is the number because 12*12=144 and 12+12=24.
9x^2 + (12+12)x +16
9x^2 +12x +12x +16
take common
3x(3x + 4) +4(3x +4)
take (3x + 4) as common
(3x +4)(3x*1 +4*1)
(3x +4)(3x +4)
(3x +4)^2

Does memory change with age?
A researcher conducts an experiment to test whether memory changes with age. They recruited 24 participants separated into four age groups. The groups differ according to the age of subjects. In group 1, all participants are 30 years old; group 2, 40 years old; group 3, 50 years old; and group 4, 60 years old. Assume that the participants are all in good health and that the groups are matched on other important variables such as years of education, IQ, gender, motivation, and so on. Each participant is shown a series of nonsense syllables (a meaningless combination of three letters such as DAF or FUM) at a rate of one syllable every 4 seconds. The series is shown twice, after which participants are asked to write down as many of the syllables as they can remember. Below is number of syllables remembered by each participant:
30 years old 40 years old 50 years old 60 years old
14 12 17 13
13 15 14 10

A shipment of sugar fills 6 containers. If each container holds 3 3/4 tons of sugar, what is the amount of sugar in the entire shipment?
Write your answer as a mixed number in simplest form.
Answer:
7 6/7 tons.
Step-by-step explanation:
2 1/5 containers = 11/5 containers, written as an improper fraction. Each container holds 3 4/7 tons of sugar; this capacity is 25/7, written as an improper fraction.
The product of these two numbers is 55/7 tons, or 7 6/7 tons.

Jordan and Amari run a 200-meter race, and Jordan wins by 23 meters. They decide to run the 200 meter race again with Jordan starting 23 meters behind the starting
line.
a. Assuming both runners run at the same pace as they did in the first race, who wins the second race?
Answer:
Jordan wins the second race.
Step-by-step explanation:
Jordan and Amari run a 200-meter race, and Jordan wins by 23 meters.
This means that while Jordan ran 200 meters, Amari will have ran 200 - 23 = 177 meters.
Thus, for each meter that Jordan runs, Amari runs 177/200 = 0.885 meters.
Second race:
Jordan starting 23 meters behind the starting line, and thus, he will have to run 200 + 23 = 223 meters.
When Jordan reaches the finish line, having ran 223 meters(200 + 23 behind), Amari will have ran 223*0.885 = 197.335 meters(< 200, so he will not have reached the finish line), and thus, Jordan wins the second race.
b) A car drives at a speed of 90kmth for 2 hours and 20 minutes
How far does the car onve?
Answer:
210 km
Step-by-step explanation:
90 * 2 is 180 (distance over 2 hours)
20 minutes is .333 hours, so 90*0.333 is about 30 km
and 180+30 is 210.
Answer:
210km
Step-by-step explanation:
2 hours=90km×2hr=180
20mins converted to a fraction is 0.333hr
90×0.333=29.97
Round 29.97 to 30
180+30
=210

A line intersects the point (3,4) and has a slope of -2. Substitute the values into point-slope form.
9514 1404 393
Answer:
y -4 = -2(x -3)
Step-by-step explanation:
The point-slope form of an equation for a line through point (h, k) with slope m is ...
y -k = m(x -h)
You have (h, k) = (3, 4) and m = -2, so your equation is ...
y -4 = -2(x -3)
