Jerry hiked along a path. From his starting position, he hiked downhill to a valley where the elevation dropped 25 meters below his starting position. Then, he hiked up to a hill that was 40 meters higher than the valley.
The following equation describes this situation.
-25 + 40 = 15
CHOOSE 1 ANSWER
1. Jerry hiked a total of 15 meters
2. the hill was 15 meters higher than the elevation of his starting point
3. None of the above
Answers
Answer:
15 represents where Jerry is after the elevation dropped 25 meters and then rose 40 meters.
Step-by-step explanation:
It's given that Jerry hiked downhill to a valley where the elevation dropped 25 meters below his starting position. Then, he hiked up to a hill that was 40 meters higher than the valley
Hiked downhill = 25 meters
Hiked up = 40 meters
The given equation is
Here, hiked downhill represented by negative sign and hiked up resents by positive sign.
So, 15 represents that Jerry hiked up 15 meters from his starting position.
(2, the hill was 15 meters higher than the elevation of his starting point)
Answer:
2.
Step-by-step explanation:
The hill was -25 + 40 = 15 meters highe than starting point.
Suppose you are interested in studying whether temperature affects spatial reasoning abilities. You decide to test spatial reasoning using completion time scores for the paper-folding test with five people, repeating the test on each person with three different temperatures (40 degrees, 60 degrees, and 80 degrees Fahrenheit).
In this experiment, the null hypothesis is that:
a. There are no differences in the mean completion times among the temperatures compared
b. There are no individual differences in the completion time means
c. The completion time mean for at least one temperature is different from another
The factor of interest is the ____________, and the dependent variable is the ___________
Answers
The null hypothesis in this situation is "There are no differences in the mean completion times among the temperatures compared".
What is a null hypothesis?This is a hypothesis that states the independent variable or factor being studied has not effect on the dependent variable.
This implies the temperature has no effect on the completion times of the paper-folding test.
What is the factor of interest?It is the effect of temperature because this is the factor being manipulated on purpose.
What is the dependent variable?This refers to the factor being studied, in this case, these are the spatial reasoning abilities, which are tested through a specific test.

x = 5t, y = t + 8 (2 points)
Answers
Answer: y = [tex]\frac{1}{5}[/tex]x + 8
Step-by-step explanation:
This is asking us to remove the parameter. In other words, we want an equation with only the relation between x and y, so we need to remove the t. There are a few ways to do this, but I am going to set one equation equal to t and then plug it into the next one.
Given:
x = 5t
Divide both sides of the equation by 5:
t = [tex]\frac{1}{5}[/tex]x

Given:
y = t + 8
Plug in:
y = ([tex]\frac{1}{5}[/tex]x) + 8

What is the range of the given function?

{x | x = -5, -4, -2, 0, 2}
{y l y = -9, -3, 0, 5, 7}
O (x | x = -9, -5, -4, -3, -2, 0, 2, 5, 7}
O tyl y = -9, -5, -4, -3, -2, 0, 2, 5, 7}
Answers
Answer:
{-9, -3, 0, 5, 7}
Step-by-step explanation:
Well, you already have the relation of the function. The domain of a function are its x coordinates and the range are all the y coordinates:
0, -3, -9, 5, 7
We write them in ascending order:
-9, -3, 0, 5, 7
And this way we get the range
It is important to check if the coordinates you are given can form a function. In this case they do, but in other cases they might not.
If you have coordinates where for example there are two equal values of x but the y is different in both, for example (1, 2) and (1, 5), this cannot be a function because y can be on two possible destinations for the same value of x.

Two sides of a parallelogram are 170 feet and 650 feet. The measure of the angle between these sides is 113°. Find the area of the parallelogram to the nearest square foot.
Answers
The area of the parallelogram is equal to 101716 ft².
QuadrilateralsThere are different types of quadrilaterals, for example: square, rectangle, rhombus, trapezoid and parallelogram. Each type is defined accordingly to its length of sides and angles. For example, the opposite sides of a parallelogram are equal and parallel.
Parallelogram AreaYou can find the parallelogram area from two formulas:
A=b * h , where b=base and h=height;A= a*b* sin(Θ), where a=side 1, b=side 2 and Θ=angle between the sides;The question gives: the length of both sides (170 ft and 650 ft) of the parallelogram and the angle between these sides (113°).
Thus, you can apply the formula: A= a*b* sin(Θ). Therefore:
A= 170 * 650* sin (113°)
A=101716 ft²

The owner of a food cart sells an average of 60 frozen treats per day during the summer. Which graph best shows the relationship between the number of days and the number of frozen treats sold?
A) A
B) B
C) C
D) D
Answers
Answer:
Answer is D
Step-by-step explanation:
Day 1 = 60
Day 2 = 120
Day 3 = 180
Day 4 = 240
Day 5 = 300
Day 6 = 360
Day 7 = 420
Day 8 = 480
The graph D will show the best relationship between the number of days and the number of frozen treats sold.
What is graph?In math, a graph can be defined as a pictorial representation or a diagram that represents data or values in an organized manner.
It is given that he sells 60 frozen treats per day so everyday the frozen treats are multiplied by 60.
We can see the linear relationship between frozen treats and number of days.
Day 1 - 60
Day 2 - 120
Day 3- 180
Day 4- 240
Day 5- 300
Day 6- 360
Day 7- 420

The following table represents the production cost g(x), in dollars, for x number of units produced by company 2:
Answers
The function of the production cost is a quadratic function, and the maximum production cost of the company is $340
How to determine the maximum production cost of the company?The function of the production cost is given as:
f(x) = 0.15x² - 6x + 400
Differentiate the function
f'(x) = 0.3x - 6
Set the function to 0
0.3x - 6 = 0
Add 6 to both sides
0.3x = 6
Divide both sides by 0.3
x = 20
Substitute x = 20 in f(x) = 0.15x² - 6x + 400
f(20) = 0.15 * 20² - 6 *20 + 400
Evaluate
f(20) = 340
Hence, the maximum production cost of the company is $340

given g(x)= cubed root of x-5,on what interval is the function negative?
a. (-infinity,-5)
b. (-infinity,5)
c. (-5,infinity)
d. (5,infinity)
Answers
The cube root function is negative on the interval (-∞, 5), so the correct option is b.
When the function is negative?
Here we have the cube root function:
g(x) = ∛(x - 5)
This is a cube root, and it is negative when the argument is negative. So the function will be negative for the values of x such that:
x - 5 < 0
x < 5
So, we can say that on the interval: (-∞, 5) the function g(x) is negative. Then the correct option is b.

We have a shape that has an area of 112 inches squared. Convert the units to centimeters squared. (HINT: Perform multiple conversions). Don’t forget to show your work.
Answers
Answer:
722.5792 cm²
Step-by-step explanation:
1 in ≈ 2.54 cm
Squaring both sides:
⇒ (1 in)² ≈ (2.54 cm)²
Apply exponent rule (ab)² = a²b²
⇒ (1)² in² ≈ (2.54)² cm²
⇒ 1 in² ≈ 6.4516 cm²
Therefore, to convert an area measured in inches squared to centimeters squared, multiply by 6.4516:
⇒ 112 in² ≈ (112 × 6.4516) cm²
= 722.5792 cm²
