Answer:
The value of f(2)≈1.57
The time it takes an object to fall 2 feet is 1.57 seconds.
Step-by-step explanation:
Consider the provided function.
[tex]f(d) = 1.11\sqrt{d}[/tex]
It takes for an object to fall a distance, d, in feet,
We need to determine f(2).
Substitute the value d = 2 in the above function.
[tex]f(2) = 1.11\sqrt{2}[/tex]
[tex]f(2)\approx 1.57[/tex]
The value of f(2)≈1.57
The time it takes an object to fall 2 feet is 1.57 seconds.

Complete the chart to find the mean, variance, and standard deviation. Remember to use commas and round numbers to the nearest tenth. Need help
Answer: The mean of the data is 433.75, variance of the data is 99667.19 and the standard deviation of the data is 315.7011.
Explanation:
The given data is 900, 35, 500 and 300.
The number of observation is 4.
Formula of mean is,
[tex]\text{Mean}=\frac{\text{Sum of observations}}{\text{Number of observations}}[/tex]
[tex]\bar{X}=\frac{900+35+50+300}{4} =433.75[/tex]
The formula of variance is given below,
[tex]\sigma^2=\frac{1}{n}\sum{(X-\bar{X})^2}[/tex]
[tex]\sigma^2=\frac{398668.75}{4}[/tex]
[tex]\sigma^2=99667.19[/tex]
The variance of the data is 99667.19
[tex]\sigma=\sqrt{99667.19}[/tex]
[tex]\sigma=315.7011[/tex]
The standard deviation of the data is 315.7011.
The other information or values of given chart is shown in the attached table.
Answer:
i. mean of the data is 402.5
ii. variance of the data is 77556.25
iii. standard deviation of the data is 278.49
Step-by-step explanation: (x - ⁻x)²
from the chart given to me, the observation are: 45, 340, 400, 825
i. mean is the summation of the observation divided by number of observation. ∈x÷n =( 45 + 340 + 400 + 825)÷ 4 = 402.5
ii. variance is the square of the difference between the observation and mean divided by the number of observation.
variance = (45-402.5)²+(340-402.5)²+(400-402.5)²+(825-402.5)²÷4=77556.5

Determine the numbers of zeros of the polynomial function
g(x) = x^4-x^5
___ zero(s)
The polynomial function g(x) = [tex]x^4 - x^5[/tex] has two zeroes, which are x = 0 and x = 1. This result is obtained by setting the polynomial equal to zero and solving for x.
Explanation:The given polynomial function is g(x) = [tex]x^4 - x^5[/tex]. To find the zeroes of the polynomial, this function should equal zero. Thus, we have[tex]x^4 - x^5[/tex] = 0.
We can simplify this function by factoring out the common factor, which is [tex]x^4[/tex]. The function thus becomes [tex]x^4[/tex](1 - x) = 0.
A product equals zero when one (or more) of the factors is zero. So, we need to set each factor to zero and solve for x. Setting [tex]x^4[/tex]= 0, yields x = 0. Setting (1 - x) = 0 results in x = 1.
This process gives two values of x that satisfy the equation [tex]x^4[/tex](1 - x) = 0 and therefore, the polynomial function g(x) has two zeroes, specifically x = 0 and x = 1.

Ron made 2/3 of a quart of hot chocolate. Each mug holds 1/3 of a quart. How many mugs will ron be able to fill ?
pretty sure its 2 mugs
Answer:
2 mugs.
Step-by-step explanation:
We have been given that Ron made [tex]\frac{2}{3}[/tex] of a quart of hot chocolate. Each mug holds [tex]\frac{1}{3}[/tex] of a quart.
To find the number of mugs that can be filled by [tex]\frac{2}{3}[/tex] quart of hot chocolate, we will divide [tex]\frac{2}{3}[/tex] by [tex]\frac{1}{3}[/tex] as:
[tex]\frac{2}{3}\div\frac{1}{3}[/tex]
Now, we will convert the division problem to multiplication problem by flipping the 2nd fraction as:
[tex]\frac{2}{3}\times\frac{3}{1}[/tex]
[tex]\frac{2\times 3}{3\times 1}[/tex]
[tex]\frac{2\times1}{1\times 1}[/tex]
[tex]2[/tex]
Therefore, Ron will be able to fill 2 mugs.

Find the equation of the line in slope-intercept form.Slope is 2/3 through (3, 4)
Answer:
y = (2/3)x + 2
Step-by-step explanation:
Start with the general slope-intercept form y = mx + b. Substitute 3 for x and 4 for y and 2/3 for m, and find the intercept, b:
4 = (2/3)(3) + b, or 2 = b. Then the desired equation is y = (2/3)x + 2.
find the equation of the line that contains the given point and the given slope. Write the equation in slope-intercept form.
1. (4, 1) slope = 6
2. (6,-3) slope= -5
3. (-8, 2) slope = -1/2
4. (-7,-1) slope = 0
Answer:
1. [tex]y=6x-23[/tex]
2. [tex]y=-5x+27[/tex]
3. [tex]y=-\frac{1}{2}x-2[/tex]
4. [tex]y=-1[/tex]
Step-by-step explanation:
- The equation of the line is:
[tex]y=mx+b[/tex]
Where [tex]m[/tex] is the slope and [tex]b[/tex] is the y-intercept.
- You have to find the y-intercept [tex]b[/tex], so, you must substitute the given point and the slope into each equation and solve for [tex]b[/tex], and then you must rewrite the equation of the line with the slope and the y-intercept calculated:
1. [tex]1=6(4)+b\\ b=-23\\ y=6x-23[/tex]
2. [tex]-3=-5(6)+b\\ b=27\\ y=-5x+27[/tex]
3. [tex]2=-\frac{1}{2}(-8)+b\\b=-2\\ y=-\frac{1}{2}x-2[/tex]
4. [tex]-1=0(-7)+b\\ b=-1\\ y=0x-1\\ y=-1[/tex]

B) x > 3/5
C) x > −3
D) x > −3/5
Answer:

There are 15 cats ready for new homes at the pet store. There are 5 cages with cats in the store. If each cage has the same number of cats, how many cats are in each cage?
There are 3 cats in each cage. They way you get this answer is by dividing the total amount of cats (15) by the total amount of cages (5). hope this helps
We find that there are 3 cats in each cage.
To find out how many cats are in each cage, we need to divide the total number of cats by the number of cages. There are 15 cats ready for new homes and 5 cages. If each cage has the same number of cats, we perform the following calculation:
Count the total number of cats: 15 cats.
Count the total number of cages: 5 cages.
Divide the total number of cats by the number of cages: 15 cats / 5 cages = 3 cats per cage.
Therefore, there are 3 cats in each cage.
