Hello! answer: 10
Step-by-step explanation:
you do a^2+b^2=c^2 meaning
8 × 8 + 6 × 6 will equal a number which then we have to find out the square root of that number meaning what number you can multiply by itself to get that number so...
8 × 8 = 64
6 × 6 = 36
64 + 36 = 100
√100 = 10
10 × 10 = 100 therefore the missing length is 10 hope that helps!
Given the function, check all transformations that occurred from the graph of the function y=x^2
Answer: left 7 units, up 4 units, and vertical compression
Step-by-step explanation:
Given
The function is [tex]y=x^2[/tex]
First shift it to the left by 7 units, so the function becomes
[tex]y=(x+7)^2[/tex]
Now compress it to make it one-third
[tex]y=\dfrac{1}{3}(x+7)^2[/tex]
Now, sift the graph upward by 4 units
[tex]y=\dfrac{1}{3}(x+7)^2+4[/tex]
Thus , the conditions are left 7 units, up 4 units, and vertical compression.

Researchers conducted a study to examine the association of clinical factors at birth with sudden infant death syndrome (SIDS) (Platt et al., 2000). The researchers randomly sampled the medical records of infants who died of SIDS from a large database. The study found 50 infants who required resuscitation at birth in 321 medical records, which produced a 90% confidence interval of 0.08 ± 0.02.
What can the researchers conclude about this confidence interval?
Researchers are________ certain that the interval (0.06,0.10) contains the proportion of 10% 90% 95 % 5% Adapted from Platt, M Archives ofDisease in' ning P. J; et al. Clinical Comparison Of SIDS And Explained Sudden Infant Deaths: How Healthy And How Normal?
Answer:
Researchers are 90% certain that the interval (0.06,0.10) contains the proportion.
Step-by-step explanation:
x% confidence interval:
A confidence interval is built from a sample, has bounds a and b, and has a confidence level of x%. It means that we are x% confident that the population mean is between a and b.
90% confidence interval of 0.08 ± 0.02.
Thus:

In solving this question, remember the annotation SOHCAHTOA
1. We are given the value of the hypotenuse and we are to determine the value of the adjacent side. COS would be used to determine this value
Cos 26 = Adjacent / hypotenuse
cos 26 = x / 15
x / 15 =0.8988
x = 15 x 0.8988 = 13.5
2. We are given the value of the hypotenuse and we are to determine the value of the opposite side. SIN would be used to determine this value
Sin = opposite / hypotenuse
sin 49 = x / 24
0.7547 = x / 24
x = 0.7547 x 24
x = 18.1
3. We are given the value of the opposite side and we are to determine the value of the adjacent side. TAN would be used to determine this value
Tan = opposite / adjacent
tan 14 = 18 /x
18 / 0.2493 = 72.2
4. We are given the value of the adjacent and we are to determine the value of the hypotenuse side. COS would be used to determine this value
cos 67 = opposite / hypotenuse
0.3907 = 5/x
x =5/ 0.3907 = 12.8
to determine the missing angle
7. tan^-1 = opposite / adjacent
8. cos^-1 = adjacent / hypotenuse
9 = sin^-1 = opposite / hyotensue
(x+3)^2+(y−4)^2=25

Explanation:
Refer to the diagram below. Notice how I've formed 3 rectangles underneath the curve. The term "right Riemann sum" refers to the idea of making each rectangle's upper right corner be on the curve. The upper left corner spills over top, meaning we have an over-estimate going on here.
Simply find the area of each rectangle, and then add up those sub areas. That will get you to the final answer.
Note how we go from x = -1 to x = 5, which is a distance of 5-(-1) = 6 units. Split three ways and each interval is 6/3 = 2 units wide.
If we started at x = -1, then increasing 2 units leads us to x = -1+2 = 1 as the first x input we compute into f(x). This is the height of the first rectangle.
Then 1+2 = 3 is the next input, meaning f(3) is the height of the next rectangle, and so on. We keep going until all rectangles are accounted for.
----------------------
You should have these rectangle heights:
329127when moving from left to right.
They add up to 3+29+127 = 159. Double that to get to the final answer of 2*159 = 318
The formula I'm using is
[tex]\Delta x*(f(x_1) + f(x_2) + \dots f(x_n))[/tex]
where x1,x2,... represents the values 1, 3, and 5. These are the x values plugged into the function to get the corresponding heights (3, 29, 127)

The school cafeteria has 500 water bottles in stock and sells a total of 60 water bottles per day. Write a function rule to represent this situation using w for the total amount of water bottles in stock at the end of d days
Answer:
W=500-60d
Step-by-step explanation:
W=the remain water bottles
500=total water bottles
60water bottles times d=total water bottles at the end of days
If the school cafeteria has 500 water bottles in stock and sells a total of 60 water bottles per day, the function rule can be expressed as w = 500 - 60d
To write a function rule representing the given situation, we can use the variables w and d, where w represents the total number of water bottles in stock and d represents the number of days.
Initially, the cafeteria has 500 water bottles in stock. Every day, they sell 60 water bottles. So, at the end of each day, the total number of water bottles in stock decreases by 60.
Therefore, the function rule can be expressed as:
w = 500 - 60d
Here, 500 represents the initial number of water bottles in stock, and 60d represents the number of water bottles sold over d days, with d being the input variable.
This function rule calculates the remaining number of water bottles in stock (w) at the end of any given number of days (d), taking into account the initial stock of 500 and the daily sales of 60 bottles.

A certain arithmetic sequence has this explicit formula for the nth term:
an = 12 + (n - 1)(5)
The same sequence has this recursive formula:
an = an-1
+
What number belongs in the blank space in the recursive formula?
A. 5
B. 12
о
C. 17
D. 4
Answer:
A. 5
Step-by-step explanation:
I assume the definitions are
an = 12 + (n-1)×5
an = an-1 + blank
if this is correct, then we have
a1 = 12
a2 = 12 + 5 = 17 = a1 + 5
a3 = 12 + 2×5 = 22 = a2 + 5
a4 = 12 + 3×5 = 27 = a3 + 5
...
we see, for an we need to add (n-1) times the number 5 to the initial a1 value.
so every new sequence number is larger by 5 than the previous one.
hence the answer.
Give the vertex for the quadratic function: f (x) = (x – 3) (x + 7)
Answer:
[tex]Vertex = (-2,-25)[/tex]
Step-by-step explanation:
Given
[tex]f(x) = (x - 3)(x + 7)[/tex]
Required
The vertex
[tex]f(x) = (x - 3)(x + 7)[/tex]
Open bracket
[tex]f(x) = x^2 -3x+7x-21[/tex]
[tex]f(x) = x^2 +4x-21[/tex]
Express -21 as 4 - 25
[tex]f(x) = x^2 +4x+4-25[/tex]
Group as:
[tex]f(x) = (x^2 +4x+4)-25[/tex]
Factorize the expression in bracket
[tex]f(x) = (x+2)^2-25[/tex]
The vertex form is:
[tex]f(x) = a(x - h)^2 + k[/tex]
Where the vertex is:
[tex]Vertex = (h,k)[/tex]
[tex]Vertex = (-2,-25)[/tex]
Identify the quantifier in the statement as either universal or existential.
No men can join a sorority.
-The quantifier is universal.
-The quantifier is existential.
Answer:
The quantifier is universal.
Step-by-step explanation:
In logic, a universal quantifier is one in which it is made clear that the stated pattern holds in all cases for the stated quantity; whereas an existential quantifier establishes that the stated quantity is a minimum floor in which the stated pattern exists.
Thus, given that the guideline says that no man can integrate a sisterhood, this implies that the guideline applies in all cases for the stated quantity, thus it is a universal quantifier.
Romeo is chucking pebbles gently up to Juliet's window, and he wants the pebbles to hit the window with only a horizontal component of velocity. He is standing at the edge of a rose garden 4.5m below her window and 5.0m from the base of the wall. How fast are the pebbles going when they hit her window?
Answer:
4.45 m/s
Step-by-step explanation:
Vertical distance, Sy = 5m
The speed of pebble when they hit her window :
Vx = Sx / t
We can obtain t using the relation :
Sy = 1/2 * at²
Where, a = acceleration due to gravity = 9.8m/s²
We can obtain t
5 = 1/2 * 9.8 * t²
5 = 4.9t²
t = √5/4.9
t = 1.01 seconds
Hence,
Speed, Vx = Sx / t
Vx = 4.5 / 1.01
Vx = 4.45 m/s
The difference of the squares of two consecutive even integers is 68. What are these numbers?
Answer:
16 and 18
Step-by-step explanation:
(n + 2)² - n² = 68
Expand
(n² + 4n + 4) - n² = 68
4n + 4 = 68
Subtract 4 from both sides
4n = 64
Divide both sides by 4
n = 16
n + 2 = 18
The two consecutive even numbers are 16 and 18.
What is Number system?A number system is defined as a system of writing to express numbers.
The difference of the squares of two consecutive even integers is 68.
We need to find the two numbers.
Let the first even number is x+2
The second number will be x
(x+ 2)² - x² = 68
(x² + 4x + 4) - x² = 68
4x + 4 = 68
Subtract 4 from both sides
4x = 64
Divide both sides by 4
x= 16
x + 2 = 18
Hence, the two consecutive even numbers are 16 and 18.

Look at the picture below?
Answer:
well, okay. its basically what you wrote. assuming there was missing information.
let's dive right into it.
we'll assume that the problem asks for integers, whole numbers.
if x would be 0,
we would get 9 numbers out, 0, -1, -2, -3, -4, -5, -6, -7 and -8
if x would one, the range would be from 7 to -8, giving us 16 numbers
if x would be 2, the range would be from 14 to -8, giving us 23 numbers (7 more each time we increasex by one)
so the answer isn't a fixed value, but a function.

In a well developed paragraph, tell me how this play, “Julius Caesar,” is timeless. How are the themes of betrayal, jealousy, pride, love, fear as relevant today as they were during the Renaissance Period (the Time period in History this was written). 8 + sentences and it must include specific details from the play (characters, events, etc)
and specific details from modern day 2021. I will ca$h app the first person to answer this correctly $5.
Julius Caesar raises many questions about the force of fate in life versus the capacity for free will. Cassius refuses to accept Caesar’s rising power and deems a belief in fate to be nothing more than a form of passivity or cowardice. He says to Brutus: “Men at sometime were masters of their fates. / The fault, dear Brutus, is not in our stars, / But in ourselves, that we are underlings” (I.ii.140–142). Cassius urges a return to a more noble, self-possessed attitude toward life, blaming his and Brutus’s submissive stance not on a predestined plan but on their failure to assert themselves.
Ultimately, the play seems to support a philosophy in which fate and freedom maintain a delicate coexistence. Thus Caesar declares: “It seems to me most strange that men should fear, / Seeing that death, a necessary end, / Will come when it will come” (II.ii.35–37). In other words, Caesar recognizes that certain events lie beyond human control; to crouch in fear of them is to enter a paralysis equal to, if not worse than, death. It is to surrender any capacity for freedom and agency that one might actually possess.
