Answer:
r < 35 or r ≥ 43
Step-by-step explanation:
We are told that when the bus driver leaves her first stop by 7:00 a.m., her route will take less than 35 minutes.
Since the time it takes to drive the route is r, then;
r < 35
Also, If she leaves after 7:00 a.M., she estimates that the same route will take no less than 43 minutes. Thus;
r ≥ 43
Thus;
r < 35 or r ≥ 43

An airplane travels at 300 mph in the direction S 45° E. What is the component form of the velocity vector?
(150 StartRoot 2 EndRoot, 150 StartRoot 2 EndRoot)
(150 StartRoot 2 EndRoot, negative 150 StartRoot 2 EndRoot)
(negative 150 StartRoot 2 EndRoot, 150 StartRoot 2 EndRoot)
(negative 150 StartRoot 2 EndRoot, negative 150 StartRoot 2 EndRoot)
Answer:ITS NOT D
Step-by-step explanation:
The component form of the velocity vector of the airplane is 150√2 mph.
What is a velocity vector?The pace at which an object's position changes is represented by a velocity vector. A velocity vector's magnitude indicates an object's speed, whereas the vector's direction indicates its direction.
The velocity vector is calculated as:-
[tex]\widehat{V}[/tex] = Vcos45
[tex]\widehat{V}[/tex] = 300 x ( 1 / √2 )
[tex]\widehat{V}[/tex] = ( 2 x 150 ) / √2
[tex]\widehat{V}[/tex] = 150√2 mph
Hence, the velocity vector of the airplane is 150√2 mph.

What is the vertex of this parabola? y= 2x² + 4x +5
Answer:
vertex = (- 1, 3 )
Step-by-step explanation:
Given a parabola in standard form
y = ax² + bx + c ( a ≠ 0 )
Then the x- coordinate of the vertex is
[tex]x_{vertex}[/tex] = - [tex]\frac{b}{2a}[/tex]
y = 2x² + 4x + 5 ← is in standard form
with a = 2, b = 4, then
[tex]x_{vertex}[/tex] = - [tex]\frac{4}{4}[/tex] = - 1
Substitute x = - 1 into the equation for corresponding value of y, that is
y = 2(- 1)² + 4(- 1) + 5 = 2 - 4 + 5 = 3
vertex = (- 1, 3 )

One number is 6 less than another number. Their sum is 50. What is the smaller number?
If x = the larger number and y = the smaller number, then which of the following systems could be used to solve the problem?
x + y = 50 and -x + y = 6
x + y = 50 and x - y = 6
x + y = 50 and x + y = 6
x - y = 50 and x + y = 6

Fran and Alex ride their bicycles from school. Fran rides 3 miles west and 2 miles south to get home. Alex rides 4 miles east and 3 miles north to get home. How many miles apart are Fran's and Alex's homes?
Answer:
The number of miles the homes of Fran's and Alex's homes are apart is approximately 8.602 miles
Step-by-step explanation:
The given displacements, d in vector form are;
For Fran;
3 miles west and 2 miles south gives d₁ = -3·i - 2·j
For Alex;
4 miles east and 3 miles north gives d₂ = 4·i + 3·j
The number of miles apart between Fran's and Alex's homes = d₂ - d₁
d₂ - d₁ = 4·i - (-3·i) + 3·j - (-2·j) = 7·i + 5·j
∴ The number of miles between Fran's and Alex's homes = 7·i + 5·j
The magnitude in miles in the distance between Fran's and Alex's homes = √(7² + 5²) = √74
∴ The magnitude in miles in the distance between Fran's and Alex's homes ≈ 8.602 miles
The magnitude in miles in the distance between Fran's and Alex's homes = The number of miles the homes of Fran's and Alex's homes are apart
∴ The number of miles the homes of Fran's and Alex's homes are apart ≈ 8.602 miles

Eli has a loan of $24,650. This loan has a simple interest rate of 3% per year. What is the amount of interest that Eli will be charged on this loan at the end of two years?
Answer:
$1479
....,..........
Answer:
If your talking about how much they are going to pay ONLY interest for two years then it is $1,479. $1,479 is the amount of money they will be paying for two years ONLY FOR INTEREST.
Step-by-step explanation:
3% of 24,650 is 739.5. That is for one year. 739.5 times 2 for two years is 1,479. Just in interest they will be paying a total of 1479 for two years. Let me know if I'm right. This should be right though. Hope it helped :)

A game show awards 30 points for each correct answer and deducts 50 points for each in correct answer. A contestant answers 2 questions incorrectly and 3 questions correctly. What is his final score?
Answer:
-10 points
Step-by-step explanation:
A game show awards 30 points for each correct answer and deducts 50 points for each in correct answer. A contestant answers 2 questions incorrectly and 3 questions correctly. What is his final score?
Let us say Initial number of points = 0
Hence,
He answers 2 incorrectly = 0 - 50 - 50
= -100
He answers 3 correctly =-100 + 30 + 30 + 30
His final score = -100 + 30 + 30 + 30
= -10 points

The diagonals of this rhombus are 8 and 16 units long. Their intersection creates four right angles, two 4-unit-long segments, and two 8-unit long segments. Given this information, find the area of the rhombus in square units (Use only the digits 0 – 9 and the decimal point, if needed, to enter a number).
Answer:
[tex]64\ \text{sq. units}[/tex]
Step-by-step explanation:
Area of a rhombus is the product of the length of the diagonals divided by two.
Length of one diagonal is 8 units and the other diagonal is 16 units
Area is given by
[tex]A=\dfrac{8\times 16}{2}\\\Rightarrow A=64\ \text{sq. units}[/tex]
The area of the rhombus is [tex]64\ \text{sq. units}[/tex]
Another approach is the diagonals have created 4 triangles where the base and is height is either 4 units long or 8 units long so the area of the rhombus would be the area of the 4 triangles.
[tex]A=4\times \dfrac{1}{2}\times 4\times 8\\\Rightarrow A=64\ \text{sq. units}[/tex]
