The time it takes the rock to reach the canyon floor is after 3.99seconds
Application of intercept to a functionThe intercept is the point where the axis is equal to zero. Give the quadratic equation that represents the height h (in feet) of an object t seconds after it is dropped expressed as:
h = -16t² + 255
The rock reaches the ground when h(t) = 0. Substitute
h = -16t² + 255
h = -16t² + 255 = 0
16t² = 255
t² = 255/16
t² = 15.9375
t = 3.99seconds
Hence the time it takes the rock to reach the canyon floor is after 3.99seconds

Compare 7/8 with 14/16 using (<,>,=)
The required 7/8 is equal to 14/16, or we can write 7/8 = 14/16.
What is simplification?Simplification involves applying rules of arithmetic and algebra to remove unnecessary terms, factors, or operations from an expression. The goal is to obtain an expression that is easier to work with, manipulate, or solve.
Here,
To compare 7/8 and 14/16, we can first convert both fractions to a common denominator. The least common multiple of 8 and 16 is 16, so we can convert 7/8 to 14/16 by multiplying both the numerator and denominator of 7/8 by 2,
7/8 = (7 × 2) / (8 × 2) = 14/16
Now we can see that both fractions have the same denominator, so we can compare their numerators directly:
7/8 = 14/16
Therefore, 7/8 is equal to 14/16, or we can write 7/8 = 14/16.

A game show contestant must randomly select a door. one door doubles her money while the other three doors leave her bankrupt. what is the probability she selects the door that doubles her money
Cindy has 26 nickels. She is getting rolls of nickels from the bank. She has enough money to get up to 10 rolls of nickels and each roll contains 40 nickels. The bank will not give partial rolls. The function that models the number of nickels Cindy will have after leaving the bank is f(r)=40r+26, where r is the number of rolls of nickels she gets.
What is the practical domain of the function?
all real numbers
r>1
all integers from 1 to 10, inclusive
{66, 106, 146, 186, 226, 266, 306, 346, 386, 426}
We know that the domain is actually the number of rolls that she gets because it is the input variable in the equation f (r) = 40 r + 26. The number of rolls that she can get can never be a negative number nor a zero nor a decimal number. However she can only get up to 10 rolls. Therefore the answer is:
all integers from 1 to 10, inclusive
Answer:
all integers from 1 to 10 inclusive

evaluate the expression a3 -b/c for a = 3, b = 2 and c = 4. write in simplest form
Final answer:
To evaluate the expression a³ - b/c for a = 3, b = 2, and c = 4, substitute the values and simplify to get 27 - 1/2, which equals 53/2 in simplest form.
Explanation:
To evaluate the expression a³ - b/c when a = 3, b = 2, and c = 4, you need to substitute these values into the expression and simplify.
Step 1: Substitute the given values. The expression becomes 3³ - 2/4.
Step 2: Calculate the power of 3. The expression is now 27 - 2/4.
Step 3: Simplify the fraction 2/4, which is equivalent to 1/2.
Step 4: The expression now reads 27 - 1/2.
Step 5: To subtract, convert 27 to a fraction which has the same denominator as 1/2. This gives us 54/2 - 1/2.
Step 6: Subtract the fractions which results in 53/2, which is the simplest form.
one number is 27 less than twice another. Their sum is 93. What are the numbers?

You can get some great new space for $23/square foot per year. You will be leasing 3,200 square feet. What will your MONTHLY rent be? a) $139 b) $3,200
c) $6,133 d) $73,600
The calculation for the monthly rent involves firstly finding the annual rent by multiplying the cost per square foot per year with the total square footage, and then dividing this annual cost by 12 to get the monthly cost. The correct answer is c) $6,133.
Explanation:To calculate the monthly rent, we first need to find out the annual rent and then divide it by 12 months. The annual rent can be found by multiplying the cost per square foot per year with the total number of square feet. So if the cost is $23/square foot per year and you are leasing 3,200 square feet, the calculation becomes: $23 * 3,200 = $73,600 for the annual rent. To calculate the monthly rent, we divide the annual rent by 12: $73,600 / 12 = $6,133.33. Therefore the monthly rent is closest to option c) $6,133.

Haresh is writing a coordinate proof involving an isosceles triangle. Haresh places his triangle on the coordinate plane such that the base of the triangle lies along the x-axis.
What coordinates should he assign to this third vertex of the isoceles triangle?
(2a, b)
(a/2, b/2)
(a/2, b)
(b, 2b)
Answer:- (a/2, b) is coordinates should he assign to the third vertex of the isosceles triangle.
Explanation:-
As the given triangle is isosceles then the median of the triangle divides it into two equal triangles such that the base of the new triangles becomes half of the original triangle[tex]=\frac{1}{2}a[/tex]
[where a is the base of the original isosceles triangle]
Since the median of the given triangle join the third vertex and the mid point of the base thus the x coordinate of the points remains same[tex]=\frac{1}{2}a[/tex] and from the graph it is clear that y coordinate of third point is b .
Thus the coordinates for the third vertex must be [tex](\frac{a}{2},b)[/tex].
Assume f(x) = g(x). Which of the following two functions may be used to represent the function 3x = x – 4? *
1 point
A) f(x) = 3x, g(x) = x – 4
B) f(x) = x – 7, g(x) = x – 4/3
C) f(x) = 3x, g(x) = 3x
D) f(x) = 7, g(x) = 3x
Since we know that the two functions are equal, f (x) = g (x), therefore when we equate the two equations the result should be similar to 3x = x – 4:
A. f(x) = 3x, g(x) = x – 4
Equating the two functions:
3x = x – 4 (correct)
So we now got our answer (A)

An astronomer wishes to measure on a photograph the distance between the image of a certain star and three other star images nearby. If eight images are nearby, how many choices of the three stars does he have?
Answer: 56
Step-by-step explanation:
Given: An astronomer wishes to measure on a photograph the distance between the image of a certain star and three other star images nearby.
The total number of images nearby = 8
The number of images chosen by astronomer = 3
Then, the number of choices of the three stars without being in order is given by :-
[tex]^8C_3=\frac{8!}{3!(8-3)!}=\frac{8\times7\times6\times5!}{3!5!}=56[/tex]
Hence, he has 56 choices .

Which of these triangle pairs can be mapped to each other using a single reflection?
Answer:
The correct answer should be figure 1 which is also attached in the solution.
Step-by-step explanation:
Reflection of any object is the mirror image of the object about any line or plane. Reflection always shows a congruent figure but inverted.
In first figure, triangle EFG makes a mirror image as triangle FGL. Here, EG is equal to GL, EF is equal to FL and angle E is congruent to angle L.
So, the figure obtained is congruent and inverted. Thus, triangles can be mapped to each other in single reflection in this image.
Figure 2 shows two congruent triangles but the reflection is not a mirror image as it should be inverted.
Figure 3 shows two congruent triangles but here they are aligned in a similar manner and not inverted. So, it is incorrect.
Figure 4 has inverted and congruent triangles but the axis about which the image is taken doesn't match with them. While reflection, they will not overlap each other and hence, it is incorrect.
Therefore, the correct answer should be figure 1 which is also attached in the solution.
