Answer:
(-2, -1).
Step-by-step explanation:
y = x² + 4x + 3
Completing the square:
y = (x + 4/2)^2 - (4/2)^2 + 3
y = (x + 2)^2 - 4 + 3
y = (x + 2)^2 - 1.
This is vertex form and the coordinates of the vertex are (-2, -1).

Each day, Robert eats 40% of the pistachios left
in his jar at that time. At the end of the second
day, 27 pistachios remain. How many pistachios
were in the jar at the start of the first day?
Answer:
At the beginning of the first day there were 75 pistachios in the jar.
Step-by-step explanation:
Given that each day, Robert eats 40% of the pistachios left in his jar at that time, and at the end of the second day, 27 pistachios remain, to determine how many pistachios were in the jar at the start of the first day you must perform the following calculations:
100 - 40 = 60
60 = 27
100 = X
100 x 27/60 = X
2700/60 = X
45 = X
60 = 45
100 = X
100 x 45/60 = X
4500/60 = X
75 = X
Therefore, at the beginning of the first day there were 75 pistachios in the jar.

Find the missing angles
Answer:
p = 95
q = 95
r = 85
s = 85
Step-by-step explanation:
85 deg & p are same-side int angles & are supplementary.
p = 180 - 85 = 95
p & q are vertical & congruent.
q = 95
p & s are supplenmentary.
s = 85
s & r are alt int angles & congruent.
r = 85
A company models its net income, in thousands of dollars, with the function f(x)=9x2−54x−144 , where x is the number of units of its product sold. How many units of its product does the company need to sell in order for the net income to equal $0?
The company needs to sell 8 units in order for the net income to equal $0
The net income function is given as:
[tex]f(x) = 9x^2 - 54x - 144[/tex]
When the net income is 0, then f(x) = 0.
So, we have:
[tex]9x^2 - 54x - 144 = 0[/tex]
Divide through by 9
[tex]x^2 - 6x - 16 = 0[/tex]
Expand the above equation
[tex]x^2 +2x- 8x - 16 = 0[/tex]
Factorize the above equation
[tex]x(x +2)- 8(x + 2) = 0[/tex]
Factor out x + 2 in the above equation
[tex](x - 8)(x + 2) = 0[/tex]
Split and solve for x
[tex]x = 8[/tex] or [tex]x =-2[/tex]
The units of product cannot be negative.
So, the value of x is [tex]x = 8[/tex]
Hence, the company needs to sell 8 units

Calculate the percent error
15 po
Mr. Boone estimates that it will take him 48 minutes to run 8 miles. It
actually takes him 60 minutes. What was his percent error? *
18%
20%
25%
30%
Answer:
20%
Step-by-step explanation:
The formula to find percent error is the absolute value of the actual value (60) minus the approximate value (48) divided by the actual value (60) times 100. So first we calculate 60 - 48 which is 12 then divide 12 by 60 which gives us 0.2 and finally multiply by 100 which gives us the answer of 20%

The zeros of a polynomial are where the graph intersects the x-axis.
Thus, by looking at the graph, we can see that it intersects the x-axis at x = -1, x = 2, and x = 3.
Answer:
x = - 1, x = 2, x = 3
Step-by-step explanation:
The zeros are the values of x on the x- axis where the graph crosses, that is
x = - 1, x = 2, x = 3 ← are the zeros

In the circle above, the measure of angle DHG can be represented by 7x - 7, and the measure of arc DG can be represented by 9x + 21. The measure of arc DG is ___ degrees.
Answer:
[tex]84^{\circ}[/tex]
Step-by-step explanation:
The measure of an inscribed angle is exactly half the measure of the arc it forms. Thus, we have the following equation:
[tex]2(7x-7)=9x+21[/tex]
Solving, we get:
[tex]2(7x-7)=9x+21,\\14x-14=9x+21,\\5x=35,\\x=7[/tex]
Plugging in [tex]x=7[/tex] into [tex]9x+21[/tex]:
[tex]\widehat{DG}=9(7)+21,\\\widehat{DG}=63+21,\\\widehat{DG}=\boxed{84^{\circ}}[/tex]

What is the recursive rule for the sequence? -1,-0.5,0,0.5,1,...
9514 1404 393
Answer:
C
Step-by-step explanation:
The subscript (n-1) is used to indicate the term previous to term (n). In this sequence, each term is 0.5 more than the previous term, so the recursive relation ...
[tex]a_n=a_{n-1}+0.5[/tex]
is the appropriate one. This matches choice C.
__
Additional comment
Of course, if the next term is 0.5 more than the last, then the previous term is 0.5 less than the present one. The sequence can be described in this "backward" fashion by the recursive relation of choice A. While that does work to describe the sequence, it is usually not the form we desire for a recursive relation.

Which equation has a graph that is a parabola with a vertex at (-2, 0)?
O y=-22²
O y = (x + 2)2
O y = (x - 2)2
Oy=x²-2
Answer: y = (x+2)^2
Aka: B
Step-by-step explanation:
Did it on edge just now !
The equation y = (x + 2)² has a graph that is a parabola with a vertex at
(-2, 0).
Option B is the correct answer.
What is a parabola?A parabola is an equation of a curve, such that any point on the curve is equidistant from a fixed point called the focus and a fixed line called the directrix of the parabola.
The equation of a parabola:
y = a(x-h)^2 + k
We have,
The equation that has a graph that is a parabola with a vertex at (-2, 0) is
y = (x + 2)².
The general equation for a parabola is y = a(x - h)² + k, where (h, k) is the vertex of the parabola.
Comparing this general equation to y = (x + 2)²,
We can see that h = -2 and k = 0, which means that the vertex of the parabola is (-2, 0).
Therefore,
The equation y = (x + 2)² has a graph that is a parabola with a vertex at
(-2, 0).

Answer this question so i dont fall victim to a siezure/heart attack from stress
Answer:
Length = 12 feet, Width = 10 feet
Step-by-step explanation:
Let the length of the bedroom be 'x' ft and the width of the bedroom be 'y' ft.
We know that the perimeter of a rectangle is given by,
P=2(length+width)
P=2(x+y)
It is given that, the length of the bedroom is 2 more than the width, so,
x=y+2
Putting the values in the equation of perimeter we get,
44=2((y+2)+y)
44=2(2y+2)
44/2 =2y+2
22=2y+2
2y=22−2
y= 20/2 =10
Therefore, x=y+2=10+2=12
Hence, the length of the bedroom is 12 feet and the width of the bedroom is 10 feet.
