Answer:
2(x+1)²-3
Step-by-step explanation:
Using the vertex formula we can write the follwoing equation
y=a(x+1)²-3
We need to solve for a
we know that when x= 2 y = 15
So we can write
15=a(2+1)²-3
15=9a-3
18=9a
a=2
Which means our final equation is
2(x+1)²-3
in standard form (just in case)
2x²+4x-1

An arc is subtended by a central angle measuring pi/2 radians. What fraction of the circumference is this arc?
Answer:
The angle is 1/4 the circumference is the arc
Step-by-step explanation:
To solve this, we are to set up a fractional relation between the central angle subtended by the arc and the total angle subtended by the circle.
At this point, we can note that the circumference of a circle actually subtends an angle of 2π radians at the center.
To express the angle subtended by the central angle [angle at the centre of the arc] as a fraction of the total circle, we do this:
The central angle of arc / total angle at the centre of the circle
= π/2 ÷2π
=[tex]\pi/2 \times \frac{1}{2\pi}= 1/4[/tex]
Therefore the angle is 1/4 the circumference is the arc

Step-by-step explanation:
Multiply 320 x 0.2
Multiply 250 x 0.1
You can think of it this way, 0.2 is 2/10 and 0.1 is 1/10 so take 20 percent of 320 and 10 percent of 250
Add them up for your answer 64 + 25 = 89

Answer:
The measure of angle E is 45 degrees
Step-by-step explanation:
To get the measure if angle E, we use the appropriate trigonometric ratio
From the question, EF is the hypotenuse since it faces the right angle
EG is adjacent to angle E
so we are going to use the trigonometric ratio that connects adjacent to the hypotenuse
This trigonometric ratio is the cosine
It is the ratio of the adjacent to the hypotenuse
Thus,
we have it that;
Cos E = EG/EF
cos E = 6√26/12√13
E = arc Cos ( 6 √26/12 √13)
E = 45 degrees

Write as an algebraic expression: Five times
the difference of the cube of y and the
square of x
A. 5y3 + 5x2
B. (5y)3 - (5x)2
C. 5(y3 - x2)
D. (5y - 5x)^6
Given:
The statement is "Five times the difference of the cube of y and the square of x".
To find:
The algebraic expression for the given statement.
Solution:
We know that,
Cube = Power 3
Square = Power 2
Difference = Minus (-)
Times = Multiplication (×)
Now,
Cube of y = [tex]y^3[/tex]
Square of x = [tex]x^2[/tex]
Difference of the cube of y and the square of x = [tex]y^3-x^2[/tex]
Five times the difference of the cube of y and the square of x is:
Required expression = [tex]5(y^3-x^2)[/tex]
Therefore, the correct option is C. The required algebraic expression for the given statement is [tex]5(y^3-x^2)[/tex].

Neil bought 2 pounds of beef. He wants to make hamburger patties that weigh 1/4 pound each. How many patties can Neil make
Answer: 8 patties
Step-by-step explanation:
There are 2 pounds of beef and Neil wants to use these to make patties that are 1/4 pounds each.
The number of patties that can be made are:
= Pounds of meat available ÷ Pound needed per patty
= 2 ÷ 1/4
= 2 * 4/1
= 8 patties

The lengths of the sides of the right triangle that is formed are x-h and y - k
Unit circlesThe triangle contained within the circle is a right angled triangle with the longest side as the hypotenuse.
Given the coordinate points (h, k) and (x, y), the lengths of the sides of the right triangle is equal to the difference between the x-ccordinate points and y-coordinate points
For the x-coordinstes
a = x - h
For the y-coordinate

The vertices of a triangle are located at the points A(0, 1), B(2, 4) and C(3, 0). The triangle is translated 5 units down to obtain triangle A′B′C′. What are the coordinates of the vertices of triangle A′B′C
Answer:
The coordinates of the vertices of triangle A'B'C' are [tex]A'(x,y) = (0,-4)[/tex], [tex]B'(x,y) = (2,-1)[/tex] and [tex]C'(x,y) = (3,-5)[/tex].
Step-by-step explanation:
According to this statement, triangle ABC must be translated 5 units in the -y direction to form triangle A'B'C'. We need to use the following operations:
[tex]A'(x,y) = A(x,y) +(0,-5)[/tex] (1)
[tex]B'(x,y) = B(x,y) +(0,-5)[/tex] (2)
[tex]C'(x,y) = C(x,y) + (0,-5)[/tex] (3)
If we know that [tex]A(x,y) = (0,1)[/tex], [tex]B(x,y) = (2,4)[/tex] and [tex]C(x,y) = (3,0)[/tex], then the new vertices of the rectangle are, respectively:
[tex]A'(x,y) = (0,-4)[/tex], [tex]B'(x,y) = (2,-1)[/tex], [tex]C'(x,y) = (3,-5)[/tex]
Talia bought a home for her pet turtle the rectangular tank is 3 feet long. 1 foot wide and 2 feet high. What is the volume?
Answer:
Volume of rectangular tank = 6 cubic feet
Step-by-step explanation:
Length of the rectangular tank = 3 feet
Width of the tank = 1 feet
And height of the rectangular tank = 2 feet
Since, tank is in the shape of a cuboid,
Volume of a cuboid = Length × Width × height
= 3 × 1 × 2
= 6 cubic feet
Therefore, volume of the rectangular tank will be 6 cubic feet.
