Answer:
See below in bold.
Step-by-step explanation:
y = -x^2 - 2x - 5
Convert to vertex form:
y = -(x^2 + 2x) - 5
y = - [(x + 1)^2 - 1] - 5
y = -(x + 1)^2 + 1 - 5
y = -(x + 1)^2 - 4
So the vertex of the graph is at (-1 , -4) and it is a maximum because the coefficient of x^2 is negative.
So the range is all values of f(x) up to and including -4.
In interval notation this is (-∞, -4].

A survey was done that asked students to indicate whether they enjoy reading or playing video games. What is the ratio of those who do not enjoy reading and those who do not enjoy playing video games? A survey was done that asked students to indicate whether they enjoy reading or playing video games
Answer:
9:3
Step-by-step explanation:
Please find attached the information required to answer this question
From the upper right corner, there are 8 people who do not like reading.
On the lower right corner of the table, there is 1 one person who does not like reading and playing video games
On the lower left corner, there are two people who do not like playing video games.
The total number of people who do not like reading = 8 + 1 = 9
The total number of people who do not like playing video games = 2 + 1 = 3
= 9 : 3

Answer:
2 50ml bottles
Step-by-step explanation:
Reading through the question, we have:
For 80mL
[tex]C_1 = \pounds 55[/tex]
For 2 50mL bottles.
The cost is calculated by the original cost + half the original cost.
i.e.
[tex]C_2 = \pounds 45 + \frac{1}{2} * \pounds 45[/tex]
[tex]C_2 = \pounds 45 + \pounds 22.5[/tex]
[tex]C_2 = \pounds 67.5[/tex]
Next, is to calculate the unit price of each.
For 80mL
[tex]C_1 = \pounds 55[/tex]
[tex]Unit\ price = 55/80[/tex]
[tex]Unit\ price = 0.6875[/tex]
For 2 50mL bottles.
[tex]C_2 = \pounds 67.5[/tex]
[tex]Unit\ price - 67.5/(2 * 50)[/tex]
[tex]Unit\ price = 67.5/100[/tex]
[tex]Unit\ price = 0.675[/tex]
By comparison, the 2 50mL is the best buy because it has smaller unit price

Gwendolyn is asked to solve the equation −4(x−3)=20. She shows the work below and states that the solution is x=−8. −4(x−3)=20−4x+12=20−4x=32x=−8 Unfortunately, Gwendolyn's work is flawed. Explain the flaw in Gwendolyn's work. Determine the correct solution to the equation.
Step-by-step explanation:
The equation is given as;
−4(x−3)=20
Gwendolyn's flaw is in the following lines;
−4x + 12 = 20
−4x = 32
When collecting like terms, the moment 12 crosses over, it becomes - 12 and not + 12
The correct solution is given as follows;
Step 1: Expand the brackets
This results to;
- 4x - (-4 * 3) = 20
-4x + 12 = 20
Step 2: Collect like terms
This results to;
- 4x = 20 - 12
- 4x = 8
Step 3: Solve for x
x = 8 / (-4)
x = -2
Express the product of (2x + 3) and (x - 5)
Answer:
Here is the answer......
Answer:
2x² - 7x - 15
Step-by-step explanation:
Given
(2x + 3)(x - 5)
Each term in the second factor is multiplied by each term in the first factor, that is
2x(x - 5) + 3(x - 5) ← distribute parenthesis
= 2x² - 10x + 3x - 15 ← collect like terms
= 2x² - 7x - 15
For the function y=12x+6, if the input is x=−4, the output is y=
Answer:
12(4) +6
48+6 = 54
y=54
Step-by-step explanation:
Step-by-step explanation:
Given function: y = 12x + 6
Input: x = -4
Replacing the value of x in function y,
y = 12 x (-4) + 6
y = -48 + 6
y = -42

Ruth Behr has ¾ liters of soda in her refrigerator. She poured 1/8 liter of soda in multiple cups. Enter the number of cups Ruth filled with soda
Answer:
6
Step-by-step explanation:
3/4*8=6
The requried number of Ruth filled with soda is 6 cups.
What is the Ratio?The ratio can be defined as the comparison of the fraction of one quantity towards others. e.g.- water in milk.
Here,
To find the number of cups Ruth filled with soda, we need to divide the amount of soda she poured into cups by the amount of soda in each cup.
Ruth poured 1/8 liter of soda into cups. To convert this to cups, we need to know that 1 liter is equal to 4 cups. So, 1/8 liter is equal to:
(1/8) x 4 cups = 0.5 cups
Ruth has 3/4 liters of soda in her refrigerator, which is equal to:
(3/4) x 4 cups = 3 cups
So, the number of cups Ruth filled with soda is:
= 3 / 0.5
= 6 cups
Thus, the requried number of Ruth filled with soda is 6 cups.

What is the Rotational speed of someone standing in Helsinki, Finland located at 60°11' N and 24°56' E.? (radius of the earth is 3960 miles)
Answer:
515.5 mph
Step-by-step explanation:
I am fairly confident we are taking the same test/quiz thing right now and I figured this one out so here ya go:
60 degrees + 11 sec = 60.183 degrees
3960 * cos(60.183) = 1969 some number in relation to the distance to the poles
2 * pi * 1969 = 12371.8
12371.8 / 24 = 515.5mph
look up "How to Calculate Rotational Speed Around Earths Axis" on YT, video is by " VAM! Physics & Engineering" that is where I found the formula stuffs

The number $y$ of calories burned after $x$ minutes of kayaking is represented by the linear function $y=4.5x$ . The graph shows the number of calories burned by hiking.
You perform each activity for 45 minutes. How many total calories do you burn?
Answer:
202.5 calories
Step-by-step explanation:
y = 4.5x where y is the calories burned and x is the minutes
Let x = 45 minutes
y = 4.5 * 45
y =202.5 calories
Answer:
The average person burns 375 – 475 calories per hour kayaking.
The number of calories burned kayaking depends on your weight, the distance and speed you kayak, and difficulty of terrain. A 200-pound (90.8kg) person will burn 477 calories per hour kayaking with moderate effort. A 150-pound person will burn 358 calories per hour with the same activity.

x = 180
∠DBC = 23
∠ABC = 157
Step-by-step explanation:
A straight line is always 180 degrees
A to D line = 180
6x + 19 + x = 180
7x + 19 = 180
-19 -19
7x = 161
/ 7 / 7
161 /7 = 23
x = 23
Then plug it in
6x + 19
6 ( 23 ) + 19 = 157

x = 23

describe how to use special product patterns to find 21^2
Answer:
21 x 21 = 441
Step-by-step explanation:
Whenever there is an exponent that is the many times you multiply the base by itself to.
Power is the result of multiplying two numbers together. The value of 21^2 is 441.
What is power?Power is the result of multiplying two numbers together. Power is typically expressed by a base number and an exponent. The base number indicates the number being multiplied. The exponent, which is a little number printed above and to the right of the base number, indicates the number of times the base number is multiplied.
Given that 21 has a power of 2, therefore, 21 to the power 2 means that 2 should be multiplied by itself twice.
21^2
= 21²
= 21 × 21
= 441
Hence, the value of 21^2 is 441.
