34. Samir can rent a moving truck from
nadezda [96]

The true statement is that renting from Company B will be cheaper if Samir drives the truck 100 miles. Then the correct option is D.

<h3>What is a linear equation?</h3>

The linear equation is given as,

y = mx + c

Where m = the slope of the line

c is the y-intercept of the line.

Let y be the total amount and x be the number of miles.

Samir can rent a moving truck from Company A for $35 plus $0.50 per mile. Then the equation will be

y = 0.5x + 35   ....1

Company B for $25 plus $0.70 per mile. then the equation will be

y = 0.7x + 25     ....2

For the same rent, the number of miles will be

0.7x + 25 = 0.5x + 35

0.2x = 10

x = 50 miles

Renting from Company B will be cheaper if Samir drives the truck 100 miles. Then the correct option is D.

A punter on Westview High School's football team kicks a ball straight up from 5 feet above the ground with an initial upward ve
Naily [24]
This can solved graphically, using algebraic manipulation or differential calculus.

Plotting the equation will generate a parabola. The vertex represents the point where the ball will reach the maximum height.

The vertex can be determined by completing the square
h = -16t2 + 45t + 5
h - 5 = -16(t2 - 45/16t)
h - 5 - 2025/64 = -16(t2 - 45/16t + 2025/1024)
(-1/16)(h - 2345/64) = (t - 45/32)^2

The vertex is
(45/32,2345/64) or (1.41,36.64)

The maximum height is 36.64 ft

Using calculus, taking the first derivative of the equation and equating to 0
dh/dt = 0 = -32t + 45
t = 45/32
Substituting this value to the equation
h = -16(45/32)^2 + 45(45/32) + 5
h = 36.64 ft

AB contains points (2, 1) and (-1, -8). What is the equation of the line parallel to AB that contains point (0, 2)?
Iteru [2.4K]

For this case we have that by definition, the equation of a line in the slope-intersection form is given by:

y = mx + b

Where:

m: It's the slope

b: It is the cut-off point with the y axis

We have two points that belong to the AB line:

(x_ {1}, y_ {1}) :( 2,1)\\(x_ {2}, y_ {2}): (- 1, -8)

We can find the slope:

m = \frac {y_ {2} -y_ {1}} {x_ {2} -x_ {1}} = \frac {-8-1} {- 1-2} = \frac {-9} {- 3} = 3

By definition, if two lines are parallel then their slopes are equal. Thus, a line parallel to AB will have slope m = 3, then the equation will be of the form:

y = 3x + b

We substitute the given point and find b:

(x, y) :( 0,2)\\2 = 3 (0) + b\\2 = b

Finally, the equation is:

y = 3x + 2

Answer:

y = 3x + 2
