Answer:

290.68 miles

Step-by-step explanation:

fixed rate 37.33 per day

mileage 0.25 per miles

allowance 110 per day

how many miles = x

110 = 37.33+0.25x

0.25x =110-37.33 = 290.68 miles

Answer:

The escape velocity from Earth is approximately 415.9 miles per hour.

The final velocity of the Tennis for the condition is 19 m/s.

acceleration: the rate at which the speed and direction of a moving object vary over time. A point or object going straight ahead is accelerated when it accelerates or decelerates. Even if the speed is constant, motion on a circle accelerates because the direction is always shifting.

Given Tennis starts moving at 4m/s to the left,

initial speed = 4 m/s

for 5s he is accelerating at a constant rate of 3m/s^2

time = t = 5 s

acceleration = 3 m/s²

to find the final velocity​,

velocity is given by,

v = u + at

u = initial speed, t = time, and a = acceleration

v = 4 + 3(5)

v = 4 + 15

v = 19 m/s

Hence velocity is 19 m/s.

Answer:

Step-by-step explanation:

The main idea you need to understand here is multiplicity, zeroes, and end behavior.

If a function has an odd degree that means that the end behaviors will be opposite so if on the right side the polynomial is going up, then on then on the left side it's going down and vice versa.

As for multiplicity, if the multiplicity or exponent of a zero is odd then it crosses the x-axis otherwise it has a turning point meaning it touches the x-axis and just turns around.

The last thing to understand is if the polynomial has a positive leading coefficient then the graph will be going up on the right side otherwise it will be going down.

We're given the function: f(x) = (x-1)(x+2)(x+5) and if you set each factor equal to zero, you can solve for the zeroes getting: x = 1, --2, and -5 as zeroes. Since the coefficients inside the factors are all positive when we multiply this out, we would get a positive leading coefficient and since the exponent of them is all one, the degree would be 3 when multiplying out the 3 binomials.

So on the right side it's going up, the left side it's going down (since odd degree) and at each zero it crosses the x-axis since they all have an odd multiplicity. This allows us to draw a rough sketch which I have provided using paint.,

The logarithm is expanded as much as possible to, log √(x^7y^-4) = (7/2) log (x) + (-2) log(y).

Simplifying the given logarithmic expression, log √(x^7y^-4).

Use the power rule of logarithms, log(a^x) = x log a.

Say, x= 1/2 and a = (x^7y^-4).

log √(x^7y^-4) = (1/2) log (x^7y^-4)

Now, use the multiplication property of the logarithms, log (ab) = log(a) + log(b). Consider a = x^7 and b = y^-4.

log √(x^7y^-4) = (1/2) log (x^7) + (1/2) log(y^-4)

Now, again use the power rule in both the terms,

log √(x^7y^-4) = (7/2) log (x) + (-4/2) log(y)

log √(x^7y^-4) = (7/2) log (x) + (-2) log(y)

This is the simplified expression.

The number of dollars each day we can spend in the remaining days is, $97

Division is a mathematical operation, in which we distribute the number in equal parts, the number on the upper side is the total quantity and the number on the bottom side is equal parts of numbers which have to be distributed.

We denote division by '÷' this symbol.

Given that,

After 1 second, the height of the ball will be 48 feet above the ground, and if the ball lands after 4 seconds of being thrown into the air the ball is 50 feet above the ground after 4.66 seconds.

So we have the function:

h(t)=64t-16t²

height h(t) is measured as the ball after t seconds.

A) To find the height of the ball after 1 second if it has been thrown, then substitute 1 for t. Thus:

h(1)=64(1)-16(1)²

Simplify:

h(1)=64-16

Subtract:

h(1)=48

Thus, after 1 second, the height of the ball is 48 feet above the ground.

B) To know how many seconds after being thrown the ball hit the ground, we have to set h(t) to 0. 0 can be defined as that it will be 0 feet above ground level: in another word, on the ground. So:

0=64t-16t²

Solve for t. Factor out a 16t

0=16t(4-t)

Zero Product Property:

16t=0, 4-t=0

Solve for t:

t=0 or t=4.

We have to ignore the first zero. So, the value of t is 4 and the ball lands after 4 seconds of being thrown into the air.

C) To calculate at what time(s) the ball is 50 feet above the ground, set h(t) to 50 and solve for t:

50=64t-16t²

First, we have to divide everything in 2 to simplify things:

25=32t-8t²

Subtract 15 from both sides:

-8t²+32t-10=0

Now, to find the zeros, we can use the quadratic formula. a=-8, b=32, and c=-10. Thus:

[tex]x=\frac{-b+\sqrt{b^{2}-4ac } }{2a}[/tex]

Substitute:

[tex]x=\frac{-32+\sqrt{(32)^2-4(-8)(-10)} }{2(-10)}[/tex]

Simplify:

[tex]x=\frac{32+\sqrt{704} }{20}[/tex]

The y-intercept is at (27/2 ,9) in the Slope Intercept Form .

What is a line's Slope Intercept Form?

A line with m as its slope, m as its y-intercept, and c as its coefficient makes up the graph of the linear equation y = mx + c. The values of m and c in this version of the linear equation known as the slope-intercept form are real numbers.

The graph of the line passes through (0,9) and (3,7) .

Slope of the line = (7 - 9)÷(3 - 0) = -2/3

Hence the line will have the equation:

y - 9 = -2/3 ( x - 0 )

or, y - 9 =  -2x/3

or, 3y - 27 = -2x

     2x + 3y = 27
