Bill spends two days driving from Point A to Point B . On the first day, he drove 2 hours longer and at an average speed 5 miles

Rainbow [258]

Answer:

His average speed on the second day is 35 miles per hour.

Step-by-step explanation:

Consider the provided information.

On first day, he drove 2 hours longer than he drove on second day.

Let x = Number of hours he drove on second day.

Then x + 2 = Number of hours he drove on first day.

It is given that he drove a total of 18 hours.

Therefore,

$x + (x + 2) = 18$

$2x + 2= 18$

$x=8$

He drove 8 hours on second day.

x + 2 = 8+2=10

He drove 10 hours on first day.

Let y = speed driven on second day.

y + 5 = speed driven on first day.

As we know: Distance = speed × time

On first day he covers a distance of:

Distance = 10(y+5)

On second day he covers a distance of:

Distance = 8(y)

Total distance = Day 1 distance + Day 2 distance

$10(y+5) + 8(y) = 680\\10y+50+8y=680\\18y=630\\y=35$

Hence, his average speed on the second day is 35 miles per hour.

Whats the domain for this equation?

fgiga [73]

Strictly speaking an equation does not have a domain. A function does. Though it may make sense to speak about a solution set to this equation over a domain.

The following could be helpful towards an answer: The equation has two sides. The left hand side is a non-linear function and the right hand side is a line with slope -1 and y-intercept of 1.

The function $\log_5(6-5^x)$ has a domain over all Reals x for which it holds $6-5^x > 0 \\6 > 5^x\\\log_5 6 > x$ so the domain of the nonlinear function is $-\infty$ .

The domain of the linear function 1-x is all Reals: $-\infty$

So, together you could say the equation's solutions are defined over the domain $-\infty$ .

Lmk if you have questions.

A football is kicked up from ground level at an initial upward velocity of 80 ft./s. The equation h=-16t^2 + 80t give the height

bixtya [17]

Answer:

Step-by-step explanation:

Note that the given height equation, which is a quadratic) has a graph that opens downward. Borrowing the quadratic formula, we find the roots of this equation, that is, the t values at which h(t) = 0:

The coefficients of this equation are a = -16, b = 80 and c = 0.

We need to find the roots of this quadratic. By the quadratic formula,

-(80) ±√(80² - 4(-16)(0) ) -80 ± 0

t = ------------------------------------- = ----------------- = -5/2 and -5/2 (seconds).

2(-16) -32

The initial height is 0 at t = 0 seconds and the final height 0 at 5/2 seconds.

According to a cookbook, the time m in minutes to cook an 8 to 12 pound turkey is given by the function m(x)=20x+20, Where is th

Alla [95]

Answer:

Domain = [8,12]

Step-by-step explanation:

The function is given by :

m(x)=20x+20

Where x is the weight of the turkey in pounds.

If x = 8 pounds

m(x)=20(8)+20 = 180

If x = 12 pounds,

m(x)=20(12)+20 = 260

We need to find the domain in this situation. Domain is set of input values while range in the result when domain is inserted in the function.

In this case, domain is [8,12]. On the other hand, range is [10,260].
