What are the vertex and x intercepts of the graph of the function below
y=(x-4)(x + 2)
Answer:
x - intercepts: (4,0) and (-2,0)
vertex: (1/2 , - 17/2)
Step-by-step explanation:
Part A
To find the x-intercepts you have to set y=0
(x-4) (x+2) = 0
Separate the parenthesis. Solve for x
x-4 = 0
x= 4
x+2 = 0
x= -2
x - intercepts: (4,0) and (-2,0)
-------------------------------------------------
Part B
vertex formula for the x: coordinate : -b/2a
Expand the function.
y = 2x^2-2x-8
a = 2
b = -2
c= -8
-b/2a = -(-2)/2(2) = 1/2
vertex x- coordinate: 1/2
Substitute 1/2 back into every "x" in the function to find the "Y" for the vertex.
y = 2(1/2)^2 -2(1/2) -8
y = -17/2
vertex: (1/2 , - 17/2)
A cell phone company has noticed that the probability of a customer experiencing a dropped call decreases as the
customer approaches a cell site base station. A company representative approached a cell site at a constant speed and
calculated the probability of a dropped call at regular intervals, and the probabilities formed the geometric sequence
08, 04.02,01,005. If the company representative continues calculating the probability of a dropped call, what will
be the next term in the sequence?
A
0.025
B)
000S
0.010
D)
0.0005
Answer:
The next term in the sequence is:
0.00221184
Step-by-step explanation:
We are given that:
A cell-phone company has noticed that the probability of a customer experiencing a dropped call decreases as the customer approaches a cell-site base station.
A company representative approached a cell site at a constant speed and calculated the probability of a dropped call at regular intervals, and the probabilities formed the recursive sequence:
0.6, 0.4, 0.24, 0.096, 0.02304.
as we can see third term is product of first two terms
fourth term is product of third and second term
fifth term is the product of fourth and third term
so, the next term in the sequence which is the sixth term will be the product of fifth and fourth term= 0.02304×0.096
= 0.00221184

What system of linear equations is shown in the graph? Enter your answers in the box.
Answer:
The equation of the line with a bold line:
slope = ( 0 - ( -1 ) ) / ( ( 2 - 0 ) )= 1/2
c = -1
Therefore, y <= ( 1 / 2 ) x - 1
The equation of the line with the dotted line:
slope = ( 1 - ( - 2 ) ) / ( 0 - 1) = - 3
c = 1
Therefore, y < - 3x + 1

Evaluate the function
f(x) = - 2x^2 + 2x + 4
Find f(1)
Answer:
f(1) = 4
Step-by-step explanation:
f(x) = - 2x^2 + 2x + 4
f(1) = - 2(1)^2 + 2(1) + 4
f(1) = -2 + 2 + 4
f(1) = 4
calculate the shaded area
Answer:
640[tex]cm^{2}[/tex]
(I hope that I am right)
Step-by-step explanation:
The bigger shape :1. First, look at the triangle as a whole -Area of a triange : [tex]\frac{Base x Height}{2}[/tex]
30 x 48 = 1440[tex]cm^{2}[/tex]
1440 ÷ 2 = 720[tex]cm^{2}[/tex]
2. Now let's look at the small triangle -20 x 16 = 320[tex]cm^{2}[/tex]
320 ÷ 2 = 160[tex]cm^{2}[/tex]
The area of the bigger shape -720 - 160 = 560[tex]cm^{2}[/tex]The smaller shape :1. Let's look at the shape as a rectangle first -Area of a rectangle = Base x Height
20 x 16 = 320[tex]cm^{2}[/tex]
2. Now let's do the little triangle -20 - 30 = 10
10 x 16 = 160[tex]cm^{2}[/tex]
160 ÷ 2 = 80[tex]cm^{2}[/tex]
The area of the smaller shape -80[tex]cm^{2}[/tex]The Area Of The Shaded Area :560 + 80 = 640[tex]cm^{2}[/tex]Before it started to rain, Bobby cut 1 8 of the grass in his yard and Danny cut 1 5 of the grass in the yard. Both boys were disappointed because they were not able to cut the entire yard. Which statement is TRUE?
A) Together the boys didn't even cut half the yard.
B) The boys were able to cut more than half the yard.
C) The boys cut almost three-fourths of the yard.
D) Together the boys cut almost the entire yard.
Answer:
Option A is correct
Step-by-step explanation:
Bobby = 1/8
Danny = 1/5
Let's add up both fractions:
1/8 + 1/5 =
1*5/8*5 + 1*8/5*8 = (multiplying both the numerator and
5/40 + 8/40 = 13/40 denominator by the opposite denominator)
Together, they both cut 13/40 of the entire lawn.
Let's check each option:
A) Together the boys didn't even cut half the yard.
True, half of the yard is 20/40, and 13/40 < 20/40
B) The boys were able to cut more than half the yard.
False, half of the yard is 20/40, and 13/40 is not greater than 20/40
C) The boys cut almost three-fourths of the yard.
False, three-fourths of the yard is 30/40, and 13/40 is not close.
D) Together the boys cut almost the entire yard.
False, the entire yard is 40/40 and 13/40 is not close.

can someone please explain this
Answer:
D) 70 degrees
Step-by-step explanation:
A triangle angle's has a total of 180 degrees
180 - 40 = 140
140/2 = 70 (the other 2 angles are equvilent angles)
Brainly plz :)
Answer:
answer below
Step-by-step explanation:
every triangle has angle that, added together, equal 180 degrees.
if the given angle is 40 and the red lines tell you the sides are equal in length (both lines have only one red line so they are the same.), calculate the angles. (hint they are both the same amount of degrees.)
My process:
180-40=140
?+?=140
70+70=140
solution= 140 degrees

Help please! Solve the inequality.
Answer:
x≤-3 1/2 or x>1
Step-by-step explanation:
The way we solve this is we simply rearrange the equation using algebra.
Step 1) For the first inequality, subtract 1/2 from both sides. This gets x by itself and turns the RHS into -3 1/2.
Step 2) For the second, add 3 to both sides. Once again, x is by itself, and the RHS is equal to 1.

Angle ACB = 38°.
Work out the length of AB.
Give your answer correct to 3 significant figures.
Answer:
AB = 154
Step-by-step explanation:
Triangle Rectangle ABC = 90
Sen 38°=0.616 = 154/250
Sen 52°=0.788 =197/250
AC =250
AB = 154
BC = 197
how many distinct 9-digit numbers can you make from four "1", three "2", and two "3"?
Answer:
2520
Step-by-step explanation:
If a nine digit number contains exactly 4 one's, 3 two's and 2 three's
We can choose the positions of the 1's in P(9/4) ways.
We can choose the positions of the 2's from the five remaining positions in P(5/3) ways
We can choose the positions of the 3's from the two remaining positions in P(2/2) ways
In this problem order doesnt matter..
= (9!/5!×4!) × (5!/3!×2!) × (2!/2!×0!)
= 2520
