Find an equation in standard form of the parabola passing through the points (1, -2), (2, -2), (3, -4)?
9514 1404 393
Answer:
y = -x^2 +3x -4
Step-by-step explanation:
We are given two points with the same y-value, so we know the axis of symmetry lies halfway between their x-coordinates, at ...
x = (1 +2)/2 = 3/2
Then the vertex form of the equation can be written ...
y = a(x -3/2)^2 +k
__
We can use two of the points to find the values of 'a' and 'k'.
For (x, y) = (1, -2)
-2 = a(1 -3/2)^2 +k = a/4 +k
For (x, y) = (3, -4)
-4 = a(3 -3/2)^2 +k = 9a/4 +k
Subtracting the first of these equations from the second, we have ...
(9a/4 +k) -(a/4 +k) = (-4) -(-2)
2a = -2
a = -1
Then k can be found from the first equation.
-2 = -1/4 +k
k = -1 3/4
So, the vertex form equation is ...
y = -(x -3/2)^2 -7/4
__
Expanding this, we can find the standard form.
y = -(x^2 -3x +9/4) -7/4)
y = -x^2 +3x -4

Answer:
622
Step-by-step explanation:
The n-th term of an arithmetic sequence is given by the formula ...
an = a1 +d(n -1)
where a1 is the first term (6), and d is the common difference (14-6=8).
Then the 78th term is ...
a78 = 6 + 8(78 -1) = 6 + 616 = 622
The 78th term is 622.

A. $2,451.12
B. $2,655.38
C. $1,225.56
D. $102.13
The annually premium for health insurance will be $2,451.12.
Option A is true.
What is Multiplication?
To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Given that;
The health insurance premium is $102.13 each check.
And, We get paid semi-monthly.
Hence, Monthly premium = 2 x $102.13
= $204.26
Since, 1 year = 12 months
Thus, The annually premium = 12 x $204.26
= $2,451.12
So, The annually premium for health insurance will be $2,451.12.

What is Tangent (Tanθ)?The tangent or tanθ in a right angle triangle is the ratio of its perpendicular to its base. it is given as,
[tex]\rm Tangent(\theta) = \dfrac{Perpendicular}{Base}[/tex]
where,
θ is the angle,
Perpendicular is the side of the triangle opposite to the angle θ,
The base is the adjacent smaller side of the angle θ.
The value of Tan(B) will be the ratio of the sides AC and BC. Therefore, the value of Tan(B) can be written as,
Tan(B) = AC / BC
Tan(B) = 8/15
Hence, the value of Tan(B) will be equal to 8/15.

y=11x+6y=11x+6 what is the x and y intercept
Answer:
y = 1 [ y intercept (0,1) ]
x = -5/11 [ x intercept : (-5/11,0) ]
Explanation:
First split this compound equation into two seperate ones:
y = 11x + 6y = 11x + 6 →
{ y = 11x + 6y → -5y = 11x → [ y = -11/5x ]
[ y = 11x + 6 ] }
________
Then find the x point of intersection by substitution.
y = -11/5x → y = 11x + 6
-11/5x = 11x + 6
-11/5x - 11x = 6
-66x/5 = 6
-66x = 30
-11x = 5
x = 5/-11
x = -5/11
_______
Then find the y point of interesection by substituting the x solution in one of the equations.
x = -5/11 → y = -11/5x
y = -11/5(-5/11)
y = 55/55
y = 1
The x-intercept is x = - 6/11.
The y-intercept is y = 6.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example:
2x + 3 = 9 is an equation.
We have,
y = 11x + 6
Now,
The x-intercept means y = 0.
So,
y = 11x + 6
0 = 11x + 6
11x = -6
x = - 6/11
The y-intercept means x = 0.
y = 11x + 6
y = 0 + 6
y = 6
Thus,
The x-intercept is x = - 6/11.
The y-intercept is y = 6.

A tape diagram. There are 65 students out of 100 students who ride the bus. There are question mark students out of 800 students who ride the bus. 65% of the 800 students at North High School ride the bus. How many students ride the bus? 100 multiplied by is equal to 800. 65 multiplied by is equal to . out of students ride the bus.
Answer:

answer two is 8
answer three is 520
answer four is 520
answer five is 800
Step-by-step explanation:
There are 520 students out of 800 ride the bus,
65% of 800 is 520,
100 multiplied by 8 is 800.
What are ratios and proportions?The majority of the explanations for ratios and proportions use fractions. A ratio is a fraction that is expressed as a:b, but a proportion says that two ratios are equal. In this case, a and b can be any two integers. The foundation for understanding the numerous concepts in mathematics and science is provided by the two key notions of ratio and proportion.
Given,
1: There are 65 students out of 100 students who ride the bus. There are question mark students out of 800 students who ride the bus.
let x student out of 800 rides the bus
so both conditions 65/100 and x/800 are in proportions,
65/100 = x/800
x = 800*65/100
x = 520
2: 65% of the 800 students at North High School ride the bus.
65% of 800 = 65/100 x 800
65% of 800 = 520
3: 100 multiplied by is equal to 800.
let x multiplied by 100 is 800
x*100 = 800
x = 800/100
x = 8
Hence 520 students out of 800 ride the bus,
65% of 800 is 520,
100 multiplied by 8 is 800.

Stu hiked a trail at an average rate of 3 miles per hour. He ran back on the same trail at an average rate of 5 miles per hour. He traveled for a total of 3 hours. The equation 3t = 5(3 – t) can be used to find the time it took Stu to hike one way. How long did it take Stu to hike the trail one way? hours How long is the trail? miles What is the total distance Stu travelled? miles
Answer:
Time taken to travel at 3 miles = 1.875
Time taken to travel at 5miles = 1.125
Total distance = 11.25
Step-by-step explanation:
D = speed x time
Time = distance/speed
Time at 3 miles per hour and 5 miles per hour
T1 = d/3
T2 = d/5
Total time = 3 hours
T1+t2 = 3 hours
d/3 + d/5 = 3
= d(1/2+1/5) = 3
d(5+3/15) = 3
d(8/15) = 3
We cross multiply
8d = 45
d = 45/8
= 5.625 miles
Total distance = 2d
2x5.625 = 11.25 miles
Since d is now known
T1 = 5.625/3 = 1.875 hours also 1 hour 52.5 minutes
T2 = 5.625/5 = 1.125 hours = 1 hour 7.5 minutes
Total distance 2xd = 11.25
