$6 is the answer. There are 16 ounces per pound, so if you divide 16 by 64, you get 4

And since every pound cost $1.50, you will have to multiply the number of pounds by the cost. 1.50 x 4 = 6

Use the distance formula from today’s lesson to find the distance between the point P(−2, 1) and the line y = 2x.

Serga [27]

Answer:

Distance from the point to the line will be $\sqrt{5}m$

Step-by-step explanation:

We have given the equation of the line is y = 2x\

So the equation of line will be y-2x = 0

Point from which we have to find the distance is (-2,1)

Distance from a point to line is given by $d=\frac{Ax+By+C}{\sqrt{A^2+B^2}}$ , here A = -2 , B = 1 and C = 0

And point x = -2 and y = 1

So $d=\frac{-2\times -2+1\times 1+0}{\sqrt{(-2)^2+1^2}}=\sqrt{5}m$

So distance from the point to the line will be $\sqrt{5}m$

A car traveling at a certain speed will travel 76 feet per second. How many miles will the car travel in 3.1 hours if it maintai

liubo4ka [24]

Keeping in mind that, there are 5280 feet in 1 mile, and 60 minutes in an hour and 60 seconds in each minute, thus 60*60 seconds in an hour, or 3600 seconds.

$\bf \cfrac{76~\underline{feet}}{\underline{sec}}\cdot \cfrac{mile}{5280~\underline{feet}}\cdot \cfrac{3600~\underline{sec}}{hr}\implies \cfrac{76\cdot 3600~mile}{5280~hr}
\\\\\\
\cfrac{570~mile}{11~hr}\approx 51.\overline{81}\frac{mile}{hr}\\\\
-------------------------------\\\\
\textit{how many miles does it do in 3.1hrs?}\quad \cfrac{570}{11}\cdot 3.1$

State the amplitude, period, phase shift, and vertical shift of the function h(t)= cos (t+1)

oksano4ka [1.4K]

Answer:

Option b.

Step-by-step explanation:

We can easily solve this problem by using a graphing calculator or plotting tool.

The function is

h(t) = cos (t +1)

Please, see attached picture below.

By looking at the picture, we can tell that the amplitude is equal to 1

The function has a period of T = 2π

We can see there is no vertical shift.

It has a phase shift of +1. (Which moves the graph to the left)

Answer:

Option b.
