Answer:
Step-by-step explanation:
The vertex would be the highest/lowest point so lets factor this first
when we factor we get
2(x^2+6x+8)
2(x+4) (x+2)
Using zero product property we find the 2 x values and x intercepts are
-4 and -2
the middle point of these points is -3
Substitute -3 for x and solve
2(-3+4) (-3+2)
2 * 1 * -1
2*-1
-2
(-3,-2) is the vertex

Grandma Gertrude's Chocolates, a family owned business, has an opportunity to supply its product for distribution through a large coffee house chain. However, the coffee house chain has certain specifications regarding cacao content as it wishes to advertise the health benefits (antioxidants) of the chocolate products it sells. In order to determine the mean % cacao in its dark chocolate products, quality inspectors sample 36 pieces. They find a sample mean of 55% with a standard deviation of 4%. The correct value of t* to construct a 90% confidence interval for the true mean % cacao is ________.
Answers
Answer:
t-value = 1.690
Step-by-step explanation:
We are given;
Sample size; n = 36
DF = n - 1
DF = 36 - 1
DF = 35
Confidence level = 90%
However, from the first table I attached, we see that the critical significance level of a 90% Confidence level is 0.05
Thus, in the second table, looking at a DF of 35 and significance level of 0.05, we have a critical t-value = 1.690

Triangle PRT - status, TS - its higher. Based on the data in the drawing, calculate the length of the altitude drawn from the vertex R to the extreme PT.
Answers
Answer:
16 cm
Step-by-step explanation:
We're to find the length of RT.
Apply the leg rule which is given as,
Hypotenuse/leg = leg/part
Hypotenuse = PR = 7.2 + 12.8 = 20 cm
Leg = RT
Part = 12.8 cm
Plug in the values
20/RT = RT/12.8
Cross multiply
RT*RT = 20*12.8
RT² = 256
RT = √256
RT = 16 cm
which equation represents a line passing through the points 4,0 and 0,3

Solve for z. 7z+ 4 – 9z = 8 z = [?]
Answers
Answer:
z = -2
Step-by-step explanation:
7z + 4 - 9z = 8 (The first step is to combine like terms, so 7z -9z = -2z)
-2z + 4 = 8 (Subtract 4 on each side)
-2z = 4 (Divide each side by -2)
z = -2
You can plug -2 back in to check, and you get:
7(-2) + 4 -9(-2) = 8
-14 + 4 + 18 = 8
8 = 8
Hopefully, this helped. Good luck!
Answer:
z=-2
Step-by-step explanation:
7z+4-9z=8
7z-9z=8-4
-2z=4 divide by-2

A (5, 3), B (2, 1), and C (-2, 4) are the coordinates of a triangle's vertices. If the triangle is reflected over the x-axis, what are the coordinates of the image?
1. A'(5, -3), B'(2, -1), C'(-2, -4)
2. A'(-5, 3), B'(-2, 1), C'(-2, 4)
3. A'(-5, 3), B'(-2, 1), C'(2, 4)
4. A'(-5, -3), B'(-2, -1), C'(2, -4)
Answers
Answer:
1 is the answer
Step-by-step explanation:
When coordinates are reflected over the x axis, the x coordinates stay the same but the y coordinates becomes either negative, if they were positive, or positive, if they had orginally been negative.

given the inequality 4x-y<=k-6, there is a minimum value of k in order for the point (5,0) to be part of a solution. what is the minimum value?
Answers
Answer:
26
Step-by-step explanation:
since the question asks for a value of k where the point (5, 0) is part of a solution, plug 5 into the x value and 0 into the y value:
4x-y<=k-6
4(5)-0<=k-6
20-0<=k-6
20<=k-6
26<=k
In this case, k can be equal to any number that is greater than or equal to 26 for the point (5, 0) to be a solution, but the question asks for the minimum value of k, meaning the smallest value. since the question asks for the smallest value, the answer we're looking for is 26.

This is a 45-45 traingle which mean that the two sides that aren't the hyptonouse are equal (because their angles are equal)
We will let x equal the length of one of the sides
we have
x²+x²=(4√2)²
2x²=32
x²=16
x=4
this means that the length of the two missing sides are 4
Now using the area of a traingle formula we can solve for the area
A=.5*b*h

A movie-theater employee notes an inverse relationship between the theater's popcorn sales
and its nacho sales. On a given night, the theater makes 990 from popcorn sales and
$1,892 from nacho sales. If on the next night the employees sell $1,452 of popcorn, how
much is earned from nachos?
Answers
Answer:
Nachos sale on next night = $ 2,776/-
Step-by-step explanation:
Data:-
On a given night theatre makes:
Popcorn sale = $990/-
Nacho Sales = $1,892/-
Next night Theatre makes:
Popcorn sale = $1,452/-
Nacho Sales = x (Let Assume)
Solution:
Given Night = Next Night
Popcorn sale/Nacho sale = Popcorn sale/Nacho sale
990 / 1,892 = 1,452 / x
0.523 = 1,452 / x
x = 1452 / 0.523
x = $2,776/-
