Answer:
We conclude that the number of milligrams of the vitamin in the drink will be: 48 mg
Step-by-step explanation:
The amount of certain Vitamin = 40 mg
Given that a new health drink has 120% of the recommended daily allowance (RDA) for a certain vitamin is 40 MG.
Thus,
The number of milligrams of the vitamin in the drink:
120% of 40
= [120/100] × [40]
= 1.2 × 40
= 48
Therefore, we conclude that the number of milligrams of the vitamin in the drink will be: 48 mg
Which of the following correctly identifies the vertices that lie on the major
axis of the conic section shown below?
(x+2)^2/49 + (y-1)^2/25 = 1
O A. (-2,-4) and (-2,6)
OB. (-7,1) and (3,1)
OC. (-9,1) and (5,1)
OD. (-2,-6) and (-2,8)
Answer:
The answer is C: (-9,1) and (5,1). took the test. Good luck!
Step-by-step explanation:
The coordinates of the vertices that lie on the major axis of the conic section can be written as (5,1) and (-9,1), so option C is correct.
What is equation?A formula known as an equation uses the equals sign to denote the equality of two expressions.
Given equation:
(x + 2)² / 49 + (y - 1)² / 25 = 1
The above equation can be simplified as,
(x + 2)² / 7² + (y - 1)² / 5² = 1
The left side has to be equal to 1, the (x + 2)² / 7² the term has to be equivalent to 1, and the term (y - 1)² / 5² to be equivalent to zero
(y - 1)² / 5² = 0, y - 1 = 0, y = 1
(x + 2)² / 7² = 1
(x + 2)² = 49
(x + 2) = ±7
x = +7 - 2 = 5
x = -7 - 2 = -9
Therefore, the coordinates of the vertices that lie on the major axis of the conic section can be written as (5,1) and (-9,1).

A company donated 4,287 books to a local library. 2,596 of them were fiction. The rest of the books were nonfiction. Amy believes there were 1,691 nonfiction books.
Answer:
Yes, Amy is right
Step-by-step explanation:
Given that:
Total number of books donated = 4287
Fiction books = 2596
Since the rest of the books are non fiction:
Number of nonfiction books :
Total number of books - number of fiction books
4287 - 2596
= 1691

Anita is eating popcorn at the movies. She eats 24 kernels in 10 minutes and 72 kernels in 30 minutes. Which TWO other ratios can represent the rate at which she is eating popcorn?
Answer:
[tex]\dfrac{96}{40}[/tex] and [tex]\dfrac{120}{50}[/tex]
Step-by-step explanation:
24 kernels in 10 minutes
In 1 minute she can eat [tex]\dfrac{24}{10}=\dfrac{12}{5}\ \text{kernels}[/tex]
let [tex]x[/tex] be the number of popcorn and minutes so the rate of eating popcorn is of the form
[tex]\dfrac{x12}{x5}[/tex]
So, when [tex]x = 6[/tex] we get
[tex]\dfrac{6\times12}{6\times 5}=\dfrac{72\ \text{kernels}}{30\ \text{minutes}}[/tex]
[tex]x[/tex] can be any real number
[tex]\dfrac{10\times 12}{10\times 5}=\dfrac{120\ \text{kernels}}{50\ \text{minutes}}[/tex]
[tex]\dfrac{8\times 12}{8\times 5}=\dfrac{96\ \text{kernels}}{40\ \text{minutes}}[/tex]
Other two ratios can be [tex]\dfrac{96}{40}[/tex] and [tex]\dfrac{120}{50}[/tex].

Again, pick a random point. I chose point (0,7). Then, we see how many units it takes to reach the next point. Let's try it. First, we move down 3 units, rise = -3, then move right 1 unit, run 1. So slope is rise over run, so -3/1 = -3. Then, for the y intercept, just see the y value when x = 0.
Answer:
y = - 3x + 7
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (0, 7) and (x₂, y₂ ) = (2, 1) ← 2 points on the line
m = [tex]\frac{1-7}{2-0}[/tex] = [tex]\frac{-6}{2}[/tex] = - 3

What are trigonometric identities?There are three commonly used trigonometric identities.
Sin x = 1/ cosec x
Cos x = 1/ sec x
Tan x = 1/ cot x or sin x / cos x
Cot x = cos x / sin x

It takes meagen 56 minutes to cook a golden turkey that weighs 12 pounds. Her compieter, chef Geraidine takes 1 hour and 16 minutes to cook a golden turkey that weighs 304 ounces. What is the differnece in pounds cooking the golden turkey er minute between chef meagen and chef chef geraidine?
Answer:
0.033 pounds/min
Step-by-step explanation:
For Meagen:
Time taken to cook golden turkey = 56 minutes
Weight of golden turkey = 12 pounds
For her competitor:
Time taken to cook golden turkey = 1 hour 16 minutes = 77 minutes
Weight of golden turkey = 304 ounces
16 ounces = 1 pound
Therefore, 304 ounces = [tex]\frac{304}{16}[/tex] = 19 pounds
Now, let us find the number of pounds cooked per minute by each chef.
Pounds cooked per minute by Meagen = [tex]\frac{12}{56} = 0.214\ pounds/min[/tex]
Pounds cooked per minute by the competitor = [tex]\frac{19}{77} = 0.247\ pounds/min[/tex]
Difference = 0.247 - 0.214 = 0.033 pounds/min

Given f of x equals 5 times x minus 6 for x less than 3, equals x squared for x between 3 and 5 inclusive, and equals 2 times x plus 15 for x greater than 5 find f '(x) and give its domain.
Answer:
D. 5 for x less than or equal to 4, equals 2x for x between 4 and 6 including 6, and equals 4 for x greater than 6 Domain: All real numbers.
Step-by-step explanation:
Find the complete diagram attached
First we need to get the derivative of the functions
For the function f(x) = 5x - 6
Using the formula
If f(x) = axⁿ
f'(x) = naxⁿ⁻¹
For the function f(x) = 5x - 6
f'(x) = 1(5)x¹⁻¹
f'(x) = 5x⁰
f'(x) = 5
For the function f(x) =x²-2
f'(x) = 2x²⁻¹
f'(x) = 2x
For the function f(x) = 4x+10
f'(x) = 1(4)x¹⁻¹
f'(x) = 4x⁰
f'(x) = 4
Get the domain
The domain is the value of the input variable x for which the functions exists. For the functions given, the domain will be on all real numbers i.e the functions will exists for any value of x on the number line.
