Find the inner product for (5, 2)×(-3, 7) and state whether the vectors are perpendicular. a. 1; no b. 1; yes c. -1; no d. -1; yes
Answer:
c. -1; no
Step-by-step explanation:
The inner product of 2 vector (a,b) and (c,d) is:
(a,b)(c,d) = a*c + b*d
If the inner product is equal to 0, the vectors are perpendicular.
So, the inner product of (5,2) and (-3,7) is equal to:
(5, 2)×(-3, 7) = 5(-3) + 2(7) = -1
The inner product is -1, it is different to 0, so the vectors are not perpendicular.

Circle B:
[tex](x+4)^2+(y+3)^2=4[/tex]
Circle F:
[tex](x-4)^2+(y-1)^2=16[/tex]
Step-by-step explanation:
We can write the equation of a circle equation with center on (h,k) and radius r as:
[tex](x-h)^2+(y-k)^2=r^2[/tex]
Then, we analyze the circle will have for the circle B:
- It has a center in x=-4 and y=-3.
- It radius can be calculated from the distance from the center (x,y)=(-4,-3) to one of its points (x,y)=(-4, -1). Then, its radius is r=2.
Then, we can write the equation as:
[tex](x-h)^2+(y-k)^2=r^2\\\\h=-4\\k=-3\\r=2\\\\(x+4)^2+(y+3)^2=4[/tex]
we analyze the circle will have for the circle F:
- It has a center in x=4 and y=1.
- It radius can be calculated from the distance from the center (x,y)=(4, 1) to one of its points (x,y)=(0, 1). Then, its radius is r=4.
Then, we can write the equation as:
[tex](x-h)^2+(y-k)^2=r^2\\\\h=4\\k=1\\r=4\\\\(x-4)^2+(y-1)^2=16[/tex]

In the lab, Goran has two solutions that contain alcohol and is mixing them with each other. Solution A is 40% alcohol and Solution B is 10% alcohol. He uses 800 milliliters of Solution A. How many milliliters of Solution B does he use, if the resulting mixture is a 30% alcohol solution?
Answer:
400milliliters
Step-by-step explanation:
Let x=ml of 30% solution B used in resulting mixture.
800+x=ml of resulting 30% solution
40%(800)+10%x=30%(800+x)
Then we can simplify the expression
0.4(800)+0.10x= 0.30(800+x)
320+0.10x=240+0.30x
80=0.20x
x= 400milliliters
Therefore, 400milliliters of 10% solution B used in resulting mixture.

How much water is wasted by the leaky faucet in 1 day? 15 drips per 30 seconds
Answer:
a. 43,200 drips
b. 4 gallons (approximately, actual value is 3.8)
c. 61 cups(approximately, actual value is 60.8, using 3.8 gallons and not 4 gallons)
Step-by-step explanation:
Here, we have a faucet wasting water at a rate of 15 drips per 30 seconds, now we want to calculate the number of drips wasted in a day
To find this, what we need to do is fund the number of seconds in a day first
There are 24 hours with 60 minutes, with each minute having 60 seconds
So the number of seconds in a day = 24 * 60 * 60 = 86,400 seconds
Now 15 drips is wasted in 30 seconds
x will be wasted in 86,400 seconds
x = (15 * 86400)/30 = 43,200 drips are wasted in a day
b. Mathematically , there are about 3,000 drips in a liter of water
So;
3,000 drips = 1 liter
43,200 drips = x liter
x = 43200/3000 = 14.4 liters of water
Mathematically,
1 liter = 0.264 gallons
So 14.4 liters = 14.4 * 0.264 = 3.8 gallon
which is equal to 4 gallons of water approximately
c. Mathematically;
1 gallon = 16 cups of water
So 3.8 gallons of water will measure 3.8 * 16 = 60.8 which is approximately 61 gallons of water

Write an equation of the line that passes through the point (–4, 6) with slope –4.
Answer:
y = - 4x - 10
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = - 4 , thus
y = - 4x + c ← is the partial equation
To find c substitute (- 4, 6) into the partial equation
6 = 16 + c ⇒ c = 6 - 16 = - 10
y = - 4x - 10 ← equation of line
Answer:
y = -4x+10
Step-by-step explanation:
Using the slope intercept form of a line
y = mx+b where m is the slope and b is the y intercept
y = -4x +b
Substituting the point in
6 = -4(-4) + b
6 = 16+b
Subtract 16 from each side
-10 =b
The equation is
y = -4x+10

the volume is 72
Step-by-step explanation:
Hi there! :)
Answer:
SA = 124 cm².
V = 72 cm³
Step-by-step explanation:
Volume of a rectangular prism: V = l × w × h
Given:
l = 4 cm
w = 9 cm
h = 2 cm
V = 4 × 9 × 2

This means that, after purchasing b books, I'm expected to have a certain m amount of dollars left with me;
This implies that the value of m can never be negative;
So, the domain of m are values of b such that [tex]m \geq 0[/tex]
When b = 0
[tex]m = 45 - 7.5(0)[/tex]
[tex]m = 45 - 0[/tex]
[tex]m = 45[/tex]
When b = 1
[tex]m = 45 - 7.5(1)[/tex]
[tex]m = 45 - 7.5[/tex]
[tex]m = 37.5[/tex]
When b = 2
[tex]m = 45 - 7.5(2)[/tex]
[tex]m = 45 - 15[/tex]
[tex]m = 30[/tex]
When b = 3
[tex]m = 45 - 7.5(3)[/tex]
[tex]m = 45 - 22.5[/tex]
[tex]m = 22.5[/tex]
When b = 4
[tex]m = 45 - 7.5(4)[/tex]
[tex]m = 45 - 30[/tex]
[tex]m = 15[/tex]
When b = 5
[tex]m = 45 - 7.5(5)[/tex]
[tex]m = 45 - 37.5[/tex]
[tex]m = 7.5[/tex]
When b = 6
[tex]m = 45 - 7.5(6)[/tex]
[tex]m = 45 - 45[/tex]
[tex]m = 0[/tex]
When b = 7
[tex]m = 45 - 7.5(7)[/tex]
[tex]m = 45 - 52.5[/tex]
[tex]m = -7.5[/tex]
There's no need to check for other values, as they will result in negative values of m;
Hence, the domain of m are:
[tex]Domain: \{0,1,2,3,4,5,6\}[/tex]
The values that are in the domain of the function are 7, 8, 9 and 10
