I just finished the quiz, and this was my only incorrect one. The correct answer is A. Also, think logically. If the sun is spread out over more area, then it must be at a smaller angle. This leads to cooler temperatures, of course.
Two stores have movies to rent
The first store charges a $12.50-per-month membership fee plus
$1.50 per movie rented
The second store has no membership fee but charges $3.50 per movie
rented.
What is the minimum number of movies a person would need to rent in a month
for the first store to be a better deal?
Answer:7
Step-by-step explanation:
In the first store, you pay 12.5+1.5x per x movies
In the second store, you pay 3.5x per x movies
The first store offers a better deal when:
12.5 + 1.5x > 3.5x
12.5 > 2x
6.25 > x
Which means if you rent minimum 7 movies in month, you should go to the first store
Answer:
7Step-by-step explanation:
We know that the first store charges $12.50 per month, which is a initial condition, and charges additionally $1.50 per movie, which is variable, this represents the ratio of change, so this can be expressed as
[tex]\$12.50 + \$1.50x[/tex]
Where [tex]x[/tex] represents movies.
Now, the second store doesn't charge and membership fee, just it charges a cost per movie which is $3.50.
Then, to solve the minimum number of movies needed to Plan A be the best choice, we just have to solve the following inequality
[tex]\$12.50 + \$1.50x> \$3.50[/tex]
Which expresses the case where Plan A is a better choice, solving for [tex]x[/tex], we have
[tex]\$12.50 + \$1.50x> \$3.50x\\\$1.50x - \$3.50x >-\$12.50\\(-1)(-2x)>(-12.50)(-1)\\2x<12.50\\x<\frac{12.50}{2}\\ x<6.25[/tex]
Which means that the minimum number of movies is 7, which is the next whole number after 6.

Step 3: 4(4 + 8x)
Step 4: Dimensions of the rectangle are 4 and 4 + 8x
In which step did the student first make an error and what is the correct step?

Step 2: 4(2) + 4(3x)
Step 3: 4 + (4+8x)
Step 3: 4 + (4• 8x)
Answer:
Step 2: 4(2) + 4(3x)
Step-by-step explanation:
By definition, the area of a rectangle is given by:
Area = Length × Width
In this case, we know that:
Area = 8 + 12x
Width = 4
Therefore:
Step 1: 8 + 12x
Step 2: 4(2) + (4)(3x)
Step 3: 4(2 + 3x)
Therefore, the dimensions of the rectangle are 4 and 2 + 3x.
The mistake was made in STEP 2. Instead of 4(2) + 4(x2) it should be 4(2) + 4(3x). Which is the second option.

Line graph because it shows differences
anyone can solve this question?
Answer:
see explanation
Step-by-step explanation:
Given the 2 equations
x² + y² = 5 → (1)
2x + y = 4 → (2)
Rearrange (2) expressing y in terms of x by subtracting 2x from both sides
y = 4 - 2x → (3)
Substitute y = 4 - 2x in (1)
x² + (4 - 2x)² = 5 ← expand factor on left side
x² + 16 - 16x + 4x² = 5
5x² - 16x + 16 = 5 ( subtract 5 from both sides )
5x² - 16x + 11 = 0 ← in standard form
(5x - 11)(x - 1) = 0 ← in factored form
Equate each factor to zero and solve for x
x - 1 = 0 ⇒ x = 1
5x - 11 = 0 ⇒ 5x = 11 ⇒ x = [tex]\frac{11}{5}[/tex]
Substitute each of these values into (3) for corresponding values of y
x = 1 : y = 4 - 2 = 2 ⇒ P(1, 2)
x = [tex]\frac{11}{5}[/tex] : y = 4 - [tex]\frac{22}{5}[/tex] = - [tex]\frac{2}{5}[/tex]
Hence Q( [tex]\frac{11}{5}[/tex], -[tex]\frac{2}{5}[/tex] )
Carter wants to know if warming up will help runners sprint faster. Thirty track and field athletes volunteered to participate in his study. He randomly assigns 15 athletes to warm-up for 10 minutes. All 30 participants sprint the same distance. He calculates the mean for each group and determines that the mean for the warm-up group was 10.7 seconds, and the mean for the other group was 13.2 seconds. To test the difference of means he re-randomized the data 54 times, and the differences are plotted in the dot plot below. What can Carter conclude from his study?
The graph shows: (3) -2.5, (6) -2.0, (9) -1.5, (12) -1.0, (6) -0.5, (4) 0.0, (3) 0.5, (7) 1.0, (3) 1.5, and (1) 2.0. The parenthesis is how many dots there is at each point.
The difference in the means is significant because a difference of 2.5 is very likely.
The difference in the means is not significant because a difference of 2.5 is very likely.
The difference in the means is significant because a difference of 2.5 is not very likely.
The difference in the means is not significant because a difference of 2.5 is not very likely.
Answer:
The answer is actually C. here's proof:
It also makes sense since 2.5 is very unlikely, so the change is significant.
Which trigonometric function is being used if we get the fraction 6/10 as our answer? Question 3 options: sin(A) cos(A) tan(A) tan(gerine)
Answer:
cos(A)Step-by-step explanation:
For angle A we have
opposite = 8
adjacent = 6
hypotenuse = 10
sin A = opposite/hypotenuse
cos A = adjacent/hypotenuse
tan A = opposite/adjacent
cot A = adjacent/opposite
6/10 = adjacent/hypotenuse = cos A
The trigonometric function of the triangle is given by cos A = 6/10
What are trigonometric relations?Trigonometry is the study of the relationships between the angles and the lengths of the sides of triangles
The six trigonometric functions are sin , cos , tan , cosec , sec and cot
Let the angle be θ , such that
sin θ = opposite / hypotenuse
cos θ = adjacent / hypotenuse
tan θ = opposite / adjacent
tan θ = sin θ / cos θ
cosec θ = 1/sin θ
sec θ = 1/cos θ
cot θ = 1/tan θ
Given data ,
Let the triangle be represented as ΔABC
where the measure of ∠ABC = 90°
Now , from the trigonometric relations ,
cos θ = adjacent / hypotenuse
So , on simplifying , we get
The measure of BC = 6 units
The measure of AB = 8 units
The measure of AC = 10 units
cos A = 6 / 10
Hence , the measure of cos A of triangle is cos A = 6 / 10

Evaluate the following expression (-5+7x1)-9x5
Final answer:
To evaluate the expression (-5+7x1)-9x5, follow the order of operations: calculate inside the parentheses, multiply, and then subtract, resulting in a final answer of 47.
Explanation:
To evaluate the expression (-5+7×1)-9×5, we need to follow the order of operations, often remembered by the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction). Let's break down the expression step by step:
Inside the parentheses: -5 + (7 × 1) = -5 + 7 = 2.
Multiply: -9 × 5 = -45.
Subtract the value obtained from step 2 from the result of step 1: 2 - (-45).
Change the subtraction of a negative value to addition: 2 + 45 = 47.
Thus, the expression (-5+7×1)-9×5 evaluates to 47.

The expression which is equivalent to (k ° h)(x) is [tex]\frac{1}{(5 + x)}[/tex] ⇒ 2nd answer
Step-by-step explanation:
* Lets explain the meaning of the composition of functions
- Composition of functions is when one function is inside of an another
function
# If g(x) and h(x) are two functions, then (g ° h)(x) means h(x) is inside
g(x) and (h ° g)(x) means g(x) is inside h(x)
* Now lets solve the problem
∵ h(x) = 5 + x
∵ k(x) = 1/x
- We need to find (k ° h)(x), that means put h(x) inside k(x)
* Lets replace the x of k by the h(x)
∵ k(x) = [tex]\frac{1}{x}[/tex]
∵ h(x) = 5 + x
- Replace the x of k by 5 + x
∴ k(5 + x) = [tex]\frac{1}{5 + x}[/tex]

Round 96 cent. Amount. To the nearest dollar
Answer:
About 1 dollar.
Step-by-step explanation:
First we must establish the possible values that 96 cents can be rounded to.
We know that 96 cents is more than nothing, or 0. We also know that a dollar is 100 cents. This means 96 cents is in between 0 and 1 dollar. We just have to determine whether 96 is closer to 100 cents or 0 cents.
To do this find the difference between 96 and each value.
100-96 = 4
96-0 =96
The difference between 96 and 100 is smaller, so the values are closer and 96 should be rounded to a dollar.
