11. Find the equation of the straight line that passes through (-4,2), (3,2) and (7,2).
Answers
Step-by-step explanation:
[tex](2 - 1 \frac{3 {3}^{2} }{?} [/tex]
Answer:
[tex]y=2[/tex]
Step-by-step explanation:
To solve this question, we can use the point-slope formula as we are given points on the line. This is the format:
[tex]y-y_{1} =m(x-x_{1} )[/tex]
The first step is to find the slope by substituting in two of the points. Let's try using (7,2) and (3,2):
[tex]2-2=m(7-3)\\0=4m\\m=0[/tex]
So now we have found that our slope is 0 meaning it is a flat line (shown by the unchanging y values through all three points).
The form for line equations is:
[tex]y=mx+c[/tex]
However, since our m=0, it is simplified to this:
[tex]y=c[/tex]
The y-value for all the points is 2, meaning c=2 (as it is also the y-intercept)
Therefore our final equation is:
[tex]y=2[/tex]
Hope this helped!
Find the distance of the point (4,4,−4) from the line r(t)=⟨−1+2t,1+2t,3−3t⟩.
Answers
Translate the given point and line together so that you get a new point and a new line that passes through the origin. This turns the problem into finding the distance between the new point,
p = (4, 4, -4) - (-1, 1, 3) = (5, 3, -7)
and the new line,
r*(t) = r(t) - ⟨-1, 1, 3⟩ = ⟨2t, 2t, -3t⟩
Let p = ⟨5, 3, -7⟩, the vector starting at the origin and pointing to p. Then the quantity ||p - r*(t)|| is the distance from the point p to the line r*(t).
Let u be such that ||p - r*(t)|| is minimized. At the value t = u, the vector p - r*(t) is orthogonal to the line r*(t), so that
(p - r*(u) ) • r*(u) = 0
I've attached a sketch with all these elements in case this description is confusing. (The red dashed line is meant to be perpendicular to r*(t).)
Solve this equation for u :
p • r*(u) - r*(u) • r*(u) = 0
p • r*(u) = r*(u) • r*(u)
and x • x = ||x||² for any vector x, so
p • r*(u) = ||r*(u)||²
⟨5, 3, -7⟩ • ⟨2u, 2u, -3u⟩ = (2u)² + (2u)² + (-3u)²
10u + 6u + 21u = 4u ² + 4u ² + 9u ²
17u ² - 37u = 0
u (17u - 37) = 0
==> u = 0 or u = 37/17
We ignore u = 0, since the dot product of any vector with the zero vector is 0.
Then the minimum distance distance between the given point and line is
||p - r*(u)|| = ||⟨5, 3, -7⟩ - 37/17 ⟨2, 2, -3⟩|| = √(42/17)
Sandra has $75 to spend on a new outfit. She finds a
sweater that costs twice as much the skirt. What is the most
the skirt can cost?
Let s represent the cost of the skirt.
Inequality: _____________________
The most the skirt can cost is _____________________.
Answers
The skirt = s
The sweater is twice as much so 2s
The total sum has to equal or be less than $75
Inequality = s + 2s <=75
Simplify to 3s <= 75
Most the skirt can cost: solve for s:
3s <= 75
Divide both sides by 3
S <= 25
The most the skirt can cost is $25
Answer:
Inequality: s ≤ 25
Max skirt cost: $25
Step-by-step explanation:
s = skirt cost
x = sweater cost
Since the sweater costs twice as much as the skirt, an equation will look like this:
x = 2s
Since her budget is $75, that means she can spend $75 or less but not more, so another equation will look like this:
x + s ≤ 75
Plug 2s into the bottom equation
2s + s ≤ 75
Add up the terms
3s ≤ 75
Divide both sides by 3, the coefficient, to isolate s, the variable.
3s/3 ≤ 75/3
s ≤ 25
That means she can spend $25 or less on a skirt.

Julio is paid 1.1 times his normal hourly rate for each hour he works over 28 hours in a
week. Last week he worked 43 hours and earned $631.90.
Enter and solve an equation to find Julio's normal hourly rate, r. Complete the explanation
how you know that your answer is reasonable.
The earnings equation is $631.90 =
Julio's hourly l'ate is $
per hour.
This is reasonable because working 43 hours at a rate of $14 per hour is
43 · 14 = 43(10 + 4) = 430 + 172 =
and $
is close to $631.90.
Answers
Answer:
43-28= 15 extra hours
normal hourly rate = a
extra hourly rate = 1.1a
28a + 15(1.1a) = 631.90
28a + 16.5a = 631.90

however this is not accurate as they can be in different placements
which can make a big difference in the total estimate.
for example:
the number could've been an 8, or an 80
they both begin with an 8
however have totally different values and could have messed up the total estimated number.

How much would you need to deposit in an account each month in order to have $50,000 in the account in 8 years? Assume the account earns 4% annual interest compounded monthly.
Answers
Answer:
$540.98
Step-by-step explanation:
future value= $ 50,000
number of deposits (n)= 8*12 = 96
rate (r) = 4% per month
= 4÷12 per annum
= 0.33% p.a
i = 0.33÷100
= 0.0033
We know,
Future value of annuity = P÷i [ (1 + i)^n - 1 ]
$50,000 = P÷ 0.0033 [ ( 1+0.0033)^96 - 1]
$50,000 * 0.0033=P [ (1.0033)^96 - 1 ]
$165 = P*0.305
P = $165÷0.305
P = $ 540.98
Rough::
let x= 1.0033)^96
log x = 96 * log (1.0033)
log x = 0.1156
x = Antilog (0.1156)
= 1.305
1.305 - 1 = 0.305

Answer:
g(x) = 2x + 2
Step-by-step explanation:
One is given the following information:
f(x) = 4x + 5f o g (x) = 8x + 13One is asked to find the following:
g(x)Remember, (f o g (x)) is another way of representing a composite function. A more visual way of representing this composite function is the following (f(g(x)). In essence, one substitutes the function (g(x)) into the function (f(x)) in places of the varaible (x). Thus, represent this in the form of an equation:
f(g(x)) = 8x + 13
Substitute the given infromation into the equation:
4(g(x)) + 5 = 8x + 13
Solve for (g(x)) in terms of (x). Remember to treat (g(x)) as a single parameter:
4(g(x)) + 5 = 8x + 13
Inverse operations,
4(g(x)) + 5 = 8x + 13
4(g(x)) = 8x + 8
g(x) = (8x + 8) ÷ 4
g(x) = 2x + 2

Answers
Answer:
The answer is s = d/t
Step-by-step explanation:
For question 12, I think this is called a literal equation, I might be wrong but I believe so it is a literal equation. They are asking you to get s on one side. And they are asking you what s is in terms of d and t. So what you do is, d = s x t. You multiply the t with the s and get d = st. Then you will divide t from both sides so, d/t = s/t, this will eliminate t from the s, and add it on to the d (distance). Which will leave you s on one side and d and t on the other. The answer is s = d/t.
Section 3
12) a) Here, as we need that s or speed is the subject so speed should be in place of distance. So, we get
s = d/t
Here, s is speed, d is distance and t is the time
12) b) We know that :
Average Speed = Total Distance/Total Time
Here, total distance is given 748 km
total time 11.5 hrs
Avg. Speed = 748/11.5
Avg. Speed = 65.04 km/h
Hence, the answer is 65.04 km/h
13) a) We know that volume of a rabbit hutch is
Volume of rabbit hutch = ½ × b × h × l
Here,
b is the breadth, h is the height and l is the length
Volume= ½ × 50 cm × 50 cm × 2.5 m
Now, here Length is in metre so we need to convert to cm
1 m = 100 cm
2.5 m = 2.5 × 100 = 250 cm
So, now
Volume= ½ × 50 cm × 50 cm × 250 cm
Volume = 50 cm × 50 cm × 125 cm
Volume = 312,500 cm³
Hence, the volume of this hutch is 312,500 cm³
13) b) Let us assume that the orange be a sphere
So, volume of orange = 4/3πr³
Here, r is the radius and π is pi
radius is 4 cm
Volume = 4/3π(4)³
Volume = 4/3 × 64π
Volume = 85.33π cm³
Volume of the orange is 85.33π cm³
