Answer:
Step-by-step explanation:
Vertex form of quadratic equation is
[tex]y = a(x-h)^2 + k[/tex]
where h and k are the x and y coordinates of the vertex, respectively.
so in this problem
if a=1 and Vertex is (-1,4) means h= -1 and k = 4
the equation will be
[tex]y = 1 (x-(-1))^{2} + 4[/tex]
[tex]y = (x+1)^2 + 4[/tex]
if a=-1 and Vertex is (-1,4) means h= -1 and k = 4
the equation will be
[tex]y = -1 (x-(-1))^{2} + 4[/tex]
[tex]y = -(x+1)^2 + 4[/tex]

What is the surface area and volume of an rectangular prism with sides 6
The surface area and volume of the rectangular prism are equal to 216 square units and 216 cubic units, respectively.
What are the surface area and the volume of a rectangular prism?Despite the brevity of the statement, we can find the answer by considering the rectangular prism as a cube, that is, every side has a measure of 6 units. The volume is equal to the product of the base area and the height of the prism and the surface area is equal to the sum of the areas of the six faces:
V = 6³
V = 216
A = 6 · 6²
A = 6³
A = 216
The surface area and volume of the rectangular prism are equal to 216 square units and 216 cubic units, respectively.

Which graph best represents y = 4x + 1?
The graph of y = 4x + 1 is a linear graph with a slope of 4, and a y-intercept of 1
The function is given as:
[tex]y = 4x + 1[/tex]
A linear equation is represented as:
[tex]y = mx + b[/tex]
Where:
m represents the slope,b represents the y-intercept.So, by comparison:
[tex]m=4[/tex]
[tex]b =1[/tex]
This means that,
The slope of the graph is 4, and the y-intercept is 1

Given:
The compound inequality is
[tex]85\leq 17m\leq 136[/tex]
To find:
The solution of given compound inequality.
Solution:
We have,
[tex]85\leq 17m\leq 136[/tex]
On dividing all sides by 17, we get
[tex]\dfrac{85}{17}\leq \dfrac{17m}{17}\leq \dfrac{136}{17}[/tex]

Answer:
The correct answer is 1.
Step-by-step explanation:
In order to solve the problem [tex]\frac{3}{9}[/tex] + [tex]\frac{2}{3}[/tex], we need can use two methods.
Method 1: Make the denominators the same.
3/9 + 2/3 =
3/9 + 6/9 =
9/9 =
1
Method 2: Turn both fraction into decimals (by dividing the numerator by the denominator.)
3/9 or 3 ÷ 9 = 0.3 (when rounded to the nearest tenth)
2/3 or 2 ÷ 3 = 0.7 (when rounded to the nearest tenth)
0.3 + 0.7 = 1
Therefore, the answer to this question is 1.
How many hours do they have to work before they go to the movies
Cell phone Plan A costs $70 per month and comes with a free $500 phone. Cell phone Plan B costs $50 per month but does not come with a phone. If you buy the $500 phone and choose Plan B, how many months is it until your cost is the same as Plan A's?
I got two different answers last time. One said 25 and the other said 11. Are either of them correct?
Answer:
25 months
Step-by-step explanation:
Plan A : $70 per month
Plan B : $50 per month + $500 as a one time cost.
So for A $70 a month would take 8 months to be at least $500
And for B it in those 8 months it would cost you $900
But we have to keep going up until they are equal
25*70 = 1750
(25*50) = 1250+500=1750
So yes 25 months is correct
it must be a equivalent fraction
In the picture there is 3 question. The equivalent fraction.

Given that,
In the picture there is 3 question.
Equivalent fractions state that two or more fractions are identical if, after simplification, they both provide the same fraction. Let's imagine that a/b and c/d are two fractions. If these fractions are simplified to produce comparable fractions, such as e/f, they are then equal to one another.
For instance, if we simplify 5/15, the resulting fraction is the same as 1/3, hence that is the equivalent fraction of 1/3.
1. We get 9/25=18/50

Answer:
Area of rectangular garden = lxb = 10*5
= 50 sq. inch
when area increases by six times
new area = 50*6 = 300 sq inches
now,
let x be increasement in both length and width
(5+x) (10+x) = 300
50 + 5x + 10x + x² = 300
x² + 15x - 250 = 0
x²+ 25x-10x -250 = 0
x(x+25) - 10 (x+25) = 0
( x-10) (x+25) = 0
either x + 25 =0
x = -25 length can be negative
0r x-10 = 0
x = 10
so 10 inches is increase on both side

A study of a population of 1,500 moths revealed that 15 out of every 75 moths in the population have gray stripes on their wings. Based on the results of this study, how many moths in the population have gray stripes on their wings?
Answer: 300 moths
Step-by-step explanation:
Since 15 out of every 75 moths in the population have gray stripes on their wings, this means the fraction of moths that have gray stripes on their wings is 15/75 = 1/5.
Therefore, out of 1500 moths, the number of moths in the population that have gray stripes on their wings would be calculated as:
= 1/5 × 1500
= 300 moths
Consider the points Q(23, 48) and R(7, 62). What is the component form of Vector Q R?
LeftAngleBracket negative 16, 110 RightAngleBracket
LeftAngleBracket negative 16, 14 RightAngleBracket
LeftAngleBracket 30, negative 14 RightAngleBracket
LeftAngleBracket 30, 110 RightAngleBracket
Answer:
The correct option is;
LeftAngleBracket negative 16, 14 RightAngleBracket which is [tex]\left \langle -16, 14 \right \rangle[/tex]
Step-by-step explanation:
The given coordinates of the points are;
The starting point, Q(23, 48) and the final point, R(7, 62)
Therefore, we have;
The x component = The x-value of R - The x-value of R = 7 - 23 = -16
The y component = The y-value of R - The y-value of R = 62 - 48 = 14
Therefore, the component form of the vector QR = [tex]\left \langle -16, 14 \right \rangle[/tex]
