Answer:
blank = -11
Step-by-step explanation:
The given function is :
[tex]f(x) = (x^2 -6x+x)+20[/tex]
We need to find the number x such that it forms the complete square.
If x = -11, then it will becomes,
[tex]f(x) = (x^2 -6x+(-11))+20\\\\f(x)=x^2-6x+9[/tex]
We can write it as follows :
[tex]f(x)=x^2-2(1)(3x)+(3)^2[/tex] ..(1)
We know that,
[tex](a-b)^2=a^2-2ab+b^2[/tex] ...(2)
Comparing (1) and (2).
[tex]f(x)=(x-3)^2[/tex]
So, if we put the blank equals -11, then it will become the perfect square.
5.02 Which equation does the graph below represents?
1. y = -1/2x
2. y = -2x
3. y = 1/2x
4. y = 2x
Answer:
2. y= -2x
Step-by-step explanation:
When the line is on an exact point like it is on (-4, 8), we can simplify it by going rise/run
Rise is the same as y (8), and your run is x (-4)
When you divide 8/-4, your answer will be -2
Therefore, the answer is y= -2x

Answer:
f(- 3) = - 16
Step-by-step explanation:
To evaluate f(- 3) with x = - 3 in the interval x ≤ - 2, then
f(- 3) = 5x - 1 = 5(- 3) - 1 = - 15 - 1 = - 16

Sachi takes 10 rounds of a rectangular park, 50 m long and 20 m wide. Find the total distance covered by him.
Answer:
700 meters
Step-by-step explanation:
A model rocket was launched from a podium 5 meters above are
an initial velocity of 98 m/s. The function that models height in me
with respect to time (in seconds) is h(t) = 5 + 987-4.9t2
meters above ground at
meters)
Answer:
See solution belowStep-by-step explanation:
Find the complete question below;
Given the height modeled by the function;
h(t) = 5 + 98t-4.9t²
when t = 0
h(0) = 5 + 98(0)-4.9(0)²
h(0) = 5
when t = 5
h(5) = 5 + 98(5)-4.9(5)²
h(5) = 5 + 490 - 122.5
h(5) = 372.5
when t = 10
h(10) = 5 + 98(10)-4.9(10)²
h(10) = 5 + 980 - 490
h(10) = 495
when t = 15
h(15) = 5 + 98(15)-4.9(15)²
h(15) = 5 + 1470 - 1,102.5
h(15) = 372.5
when t = 20
h(10) = 5 + 98(20)-4.9(20)²
h(10) = 5 + 1960 - 4.9(400)
h(10) = 1965- 1960
h(10) = 5

Olivia wants to know the proportion of students at her school who use a
certain social media app. She interviews a random sample of students at
her school. She finds that 30% of the students in the sample use the app.
What conclusion can she draw from the sample?
А
It is likely that about 30% of the students at her school use the app.
B Exactly 30% of the students at her school use the app.
Every random sample would find that 30% of the students use
the app
It is likely that 30% of the students at her school were selected for
the sample.
Answer:
A
Step-by-step explanation:
Random sampling is a sampling method where each sample has an equal chance of being chosen. The random sample chosen is meant to be an unbiased representation of the population.
If 30% of the sample uses the app, it means that 30% of the population are likely to use the app

= 5
Does anyone know this if you could help me I would appreciate it
Answer:
C, B
Step-by-step explanation:
Basically to find the slope you take the rise over run. How many squares does the line go up, over how many does it go left or right. As you can see in the diagram, it goes up 2 squares and goes left 1 square, giving the slope 2/1, which is 2.
The slope of a horizontal line is straight, which means it goes up 0, so automatically your answer is zero, because dividing anything by 0 is 0.
3. A computer is priced at $65,000 plus value added tax at 15%. What amount does the computer actually cost the customer?
Answer:
$74,750
Step-by-step explanation:
Given that,
The cost of a computer = $65,000 + value added tax at 15%
We need to find the amount the computer actually cost the customer.
Total cost = Cost of computer + VAT at 15%
[tex]=65000+65000\times \dfrac{15}{100}\\\\=\$74,750[/tex]

Given:
The cost of the T.V. for Colin = £ 800.
The rate of depreciation per year = 4%
Time period = 3 years
To find:
How much will it be worth in 3 years? Give your answer to the nearest penny where appropriate.
Solution:
To solve the above-given problem, we will use the following formula:
where
A = the final value after depreciation
P = the present value
R = rate of depreciation
n = time period
Now, on substituting the given values in the formula, we get
we will round the above answer to its nearest penny where appropriate

Answer:
radius=6
Step-by-step explanation:
arc ACB=6xPi
Pi=3.14159
arc ACB=18.85 (rounded to 2 places)
ACB is a half circle so a full circle would be 18.85x2 or 37.7
circumference (whole circle)=2 x Pi x radius
37.7=2 x 3.14159 x radius
radius= 37.7/(2 x 3.14159)
radius=6
