What is the vertex of y=x2 – 2x + 3?
O (-1,3)
O (1, 2)
O (3, 1)
O (2, -1)
Answer:
vertex = (1, 2 )
Step-by-step explanation:
Given a quadratic in standard form
y = ax² + bx + c ( a ≠ 0 )
Then the x- coordinate of the vertex is
x = - [tex]\frac{b}{2a}[/tex]
y = x² - 2x + 3 ← is in standard form
with a = 1, b = - 2 , then
x = - [tex]\frac{-2}{2}[/tex] = 1
Substitute x = 1 into the equation for corresponding value of y
y = 1² - 2(1) + 3 = 1 - 2 + 3 = 2
vertex = (1, 2 )

A semicircle with diameter 8 inches is connected to a triangle with a base length of 8 inches. The height of the triangle is 3 inches. What is the area of the composite figure? (8π + 6) in.2 (8π + 12) in.2 (8π + 18) in.2 (8π + 24) in.2
Answer:
B or (8π + 12) in.2
Step-by-step explanation:
The area of the composite figure = (8π + 12) [tex]inch^{2}[/tex].
How to estimate the area of the composite figure?The composite figure is made up of a semicircle and an isosceles triangle.
The area of a semicircle = (1/2)π[tex]r^{2}[/tex]
radius = 4 inch
When we substitute, the area of the semicircle is
= (1/2)π[tex]\times[/tex]16
= 8π [tex]$inch^{2}[/tex]
Area of the isosceles triangle = (1/2)bh
= (1/2)(4+4)[tex]\times[/tex]3
= 12 [tex]inch^{2}[/tex]
We add the two areas to acquire the area of the composite figure to be: (8π + 12) [tex]inch^{2}[/tex]
The area of the composite figure = (8π + 12) [tex]inch^{2}[/tex].
Therefore, the correct answer is option b. (8π + 12) in.2

Step-by-step explanation:
hope this helps
Answer:
x² + 4xy + 4y²
Step-by-step explanation:
(x + 2y)²
= (x + 2y)(x + 2y)
Each term in the second factor is multiplied by each term in the first factor, that is
x(x + 2y) + 2y(x + 2y) ← distribute parenthesis
= x² + 2xy + 2xy + 4y² ← collect like terms
= x² + 4xy + 4y²

Solve for r
5/12 · r = 10/11
Write your answer as a fraction or as a whole or mixed number.
r = ___
Answer:
r = 2 2/11
Step-by-step explanation:
5/12 · r = 10/11
Multiply each side by 12/5 to isolate r
(12/5) *5/12 · r = 10/11* 12/5
r = 12/11 * 10/5
r = 12/11*2
r = 24/11
r = 2 2/11
Answer:
11/24
Step-by-step explanation:
Multiply both sides of this equation by 12/5 to isolate r:
(5/12)(12/5)
r = ------------------ = 55/120
(12/5)(10/11)
r = 55/120 = 11/24
What are the two shapes of cross-sections we could create by slicing the pyramid perpendicular to its base?
A. B. C. D.
Answer:
triangle and trapezoid
Step-by-step explanation:
The correct answer is Option B) Rectangle
What is a pyramid?A solid bounded by plane faces of which one, called the base, is a polygon and the other faces are all triangles meeting at a point outside the polygon.
Given here that the base of the pyramid is a rectangle and thus the plane slicing through the vertex along the perpendicular distance will result in two congruent rectangles at the base as the vertex projects on the midpoint of a rectangle.
Hence, the correct option is B)

Jimmy purchased a package of jelly beans that contained 75 jellybeans. Out of the 75 jellybeans, 8 are pink, 17 are orange, 22 are red, 18 are green, 6 are white and 4 are black.Jimmy later noticed that the package of jellybeans contained a hole and two jellybeans dropped out of the package while he was walking home.
Find completion to question in comment section.
Answer:
D. One of the jellybeans that slipped out was orange and one was black
Step-by-step explanation:
We calculate the option with the highest probability of occurrence :
Total number of jellybean = 75
n(T) =75
n(Pink) = 8
n(red) = 22
n(Orange) = 17
n(green) = 8
n(white) = 6
n(black) = 4
We assume that the jelly beans must have slipped out one after the other.
Evaluating the options :
A.)
P(pink) and P(white)
8/75 * 6/74 = 0.0086486
B.)
P(green) and P(green)
8/75 * 7/74 = 0.0100900
C.)
P(white) and P(white)
6/75 * 5/74 = 0.0054054
D.)
P(orange) and P(black)
17/75 * 4/74 = 0.0122522
From the probability values obtained, the highest is D. Hence, the most likely to have occurred is One of the jellybeans that slipped out was orange and one was black

Given a mean of 75 and a standard deviation of 7,
how many students out of 500 would score higher
than 68?
Answer:
421 students out of 500 would score higher than 68
Step-by-step explanation:
P(X>68) = normalcdf(68,100,75,7) = 0.841 = 84.1%
Therefore, 84.1% of 500 students is 421 (remember to round up).
There are 421 students out of 500 who would score higher than 68 if the mean is 75 and the standard deviation is 7.
What is the standard deviation?
The standard deviation mathematical and statistical analysis tool used to explain the diversity of treatments or values around the Mean is the standard deviation, which is also known as the square root of variance.
Given a mean of 75 and a standard deviation of 7,
Mean μ = 75
SD σ = 7
By using the normal distribution,
P(X > 68) = P( z > (68-μ)/σ)
P(z > 1)
By using z-table, we get
= 0.8413
Therefore, 84.1% of 500 students is 421 (rounded to the nearest integer).
Hence, 84.1% of students out of 500 would score higher than 68.
