Answers
Answer:
D) The vectors point in opposite directions.
Step-by-step explanation:
got it right on edge :)
see graph below
Given vectors u = (-2,1) and v =( 4, -2) represents the vectors point in opposite directions.
What is vectors?
"Vectors is a quantity which gives us both magnitude and direction of the given quantity."
According to the question,
Given vectors u(-2,1) and v(4,-2) represented on the graph.
From the graph we conclude that given vectors u and v
Does not form obtuse angle of approximately 93° , 96° or 127°.
The vector 'u(-2,1)' is in second quadrant and v(4,-2) is in fourth quadrant.
Second quadrant and fourth quadrant are in opposite direction.
Hence, we conclude the vectors point in opposite directions.

The amount of time it takes Isabella to wait for the bus is continuous and uniformly distributed between 3 minutes and 17 minutes. What is the probability that it takes Isabella more than 5 minutes to wait for the bus
Answers
Answer:
P(X>5) = 0.857
Step-by-step explanation:
Let X [tex]\sim[/tex] uniform(3.17)
[tex]f(x) = \dfrac{1}{17-3} ; \ \ \ 3 \le x \le 17[/tex]
The required probability that it will take Isabella more than 5 minutes to wait for the bus can be computed as:
[tex]P(X > 5) = \int ^{17}_{5} f(x) \ dx[/tex]
[tex]P(X > 5) = \int ^{17}_{5} \dfrac{1}{17-3} \ dx[/tex]
[tex]P(X > 5) =\dfrac{1}{14} \Big [x \Big ] ^{17}_{5}[/tex]
[tex]P(X > 5) =\dfrac{1}{14} [17-5][/tex]
[tex]P(X > 5) =\dfrac{12}{14}[/tex]
P(X>5) = 0.857

8 times the difference between a number and 6 is equal to 4 times the number.
What is the number?
OA. 12
OB. 4
OC. 16
OD. 48
Answers
Answer:
it's either A (12) or B(4) but I think it's 12
Step-by-step explanation:
if we make it into an equation, we get
8(x-6)=4x
8x-48=4x
-48=-4x
-12=-x
x=12
the reason why it might be 4 as well is if we switch the order
8(6-x)=4x
48-8x=4x
48=12x
x=4
So both of those could be correct, but I'm thinking that because they said between a number and 6, then x goes first, so therefore, I think it is 12

What is the x -coordinate of the x-intercept of the function 2/3y=−6x+12?

Answer:
y=9x+18
Step-by-step explanation:
to get 9, use the rise over run way. Using that, I got 9/1, which is equivalent to 9. Then you MUST add x after, so then you get 9x. The last number is always the y intercept, or where the line meets the vertical line. That was 18.

If 2000 square centimeters of material is available to make a box with a square base and an open top, find the largest possible volume of the box.
volume=------------cm^3
Answers
Answer:
8586.7cm^3
Step-by-step explanation:
We can denote the side of the base square as "x" in cm
We can also denote the height as "y" in cm
(x^2 * y) = V(x,y)
The surface area can be written as
(x^2 + 4xy = 2000)
We can make "y" as subject of the formula
4xy = 2000 - x^2
y=( 2000 - x^2)/ 4x----------eqn(*)
Substitute "y" into V(x,y)
(x*y)= x^2 * (2000-x^2)/4x = V(x)
We can divide the numerator by the denominator
y= x^2 (500/x - x/4)----------eqn#)
We can take the derivatives
V'(x)= 500 - 3/4x^2
If we set V'(x)=0 we have
500=3/4x^2
2000=3x^2
x^2=666.7
x=√666.7
x=25.8cm
From eqn(*)
y=( 2000 - x^2)/ 4x
y=(2000 - 25.8^2)/(4×25.8)
y=12.9cm
(x^2 * y) = V(x,y)
25.8^2 × 12.9
V(x,y)= 8586.7cm^3
Hence find the largest possible volume of the box is 8586.7cm^3

Answer:
A = 125, B = 55, C = 125
Step-by-step explanation:
A line that is cut into two by a line has two angles that equal 180. So angle A + angle D is 180. Angle D = 55 so 180 - 55 = 125. You do the same for every angle but look at the line as being cut into two in different directions for angles a and b and angles c and d.

The area
The area of a triangle ABC is 64 cm². Given AB = 11 cm and BC = 15 cm, Find ABC. Trying to find angle B.
Answers
Answer:
∠B ≈ 50.9°
Step-by-step explanation:
The area formula for a triangle can be used to find the missing angle.
Area formulaWe don't want confusion between A for area and angle A, so we define Q as the area of the triangle with sides a, c, and included angle B. In this scenario, 'a' represents side BC (opposite angle A), and 'c' represents side AB (opposite angle C).
Q = (1/2)ac·sin(B)
Unknown angleSolving for B, we have ...
2Q/(ac) = sin(B)
B = arcsin(2Q/(ac)
B = arcsin(2(64)/(11(15)) = arcsin(128/165)
∠B ≈ 50.9°

mark can cleaN the house in 7 hours. when he cleans the same house with wend, it takes them 3 hours to clean the house. how long would it rake wendy to clean the house by herself
Answers
Answer:5.25
Step-by-step explanation:
3(1/7 + 1/x) = 1
3([x + 7]/7x) = 1
3x + 21 = 7x
4x = 21
x = 21/4 OR 5.25
It will take wendy 5.25hrs to clean the house by herself.
Let x be the time taken by mark to clean the house by herselfLet y be the time taken by wend to clean the house by herselfLet a be the time it took the two to clean the house together.In order to get the time it take wendy to clean the house by herself, we will use the expression:
1/a = 1/x + 1/y
1/3 = 1/7 + 1/y
1/y = 1/3 - 1/7
1/y = 7-3/21
1/y = 4/21
y = 21/4
y = 5.25hrs
Hence it will take wendy 5.25hrs to clean the house by herself.
