You probably forgot to mention the options. After a little research, I was able to get the complete question with the mentioned options you should have mentioned. The potential complete question is:

Ellen plans to leave an 18 percent tip with her $23.75 lunch bill. Which of these expressions could she use to determine her total bill?

Check all that apply.

(1.18)(23.75) 23.75 – [(0.18)(23.75)] 23.75 + [(0.18)(23.75)] (0.18)(23.75)

Answer:

The expression [tex]23.75\:+\:\left[\left(0.18\right)\left(23.75\right)\right][/tex] will determine her total bill.

Step-by-step explanation:

Total lunch bill = $23.75

As he pans to 18% tip of the total bill, so the expression will be:

[tex]=23.75\:+\:\left(\:18\%\:\:of\:\:23.75\:\right)[/tex]

[tex]=23.75\:+\:\left(\:\frac{18}{100}\:\times \:23.75\:\right)[/tex]

[tex]=23.75\:+\:\left(\:0.18\times \:23.75\:\right)[/tex]

or

[tex]=23.75\:+\:\left[\left(0.18\right)\left(23.75\right)\right][/tex]

Therefore, the expression [tex]23.75\:+\:\left[\left(0.18\right)\left(23.75\right)\right][/tex] will determine her total bill.

Answer:

(1.18)(23.75)

23.75 + [(0.18)(23.75)]

NEGATIVE 3 AND 2 THIRDS

Step-by-step explanation:

Answer:

A:zero

B:negative

C:positive

Step-by-step explanation:

the key words just tell you for A it was cruising B it was negative because descending and C is positive because ascending.

The correct explanation for the slope will be;

a) When the plane is cruising at an altitude of 37,000 feet above sea level, then the slope is zero.

b) When the plane is descending at rate of 1000 feet per minute, then the slope is negative.

c) When the plane is ascending at a rate of 2000 feet per minute. then the slope is positive.

What is mean by Slope?

The slope of line is a measure of its steepness.

Given that;

During its flight, the elevation e (in feet) of a certain airplane and its time

in minutes since takeoff, are related by a linear equation.

In the graph, time represented on the horizontal axis and elevation on the vertical axis.

Now,

a) When the plane is cruising at an altitude of 37,000 feet above sea level, then the slope is zero.

Because the plane is cruising.

b) When the plane is descending at rate of 1000 feet per minute, then the slope is negative.

Because the plane is descending.

c) When the plane is ascending at a rate of 2000 feet per minute. then the slope is positive.

Because the plane is ascending.

Thus, The correct explanation for the slope will be;

a) When the plane is cruising at an altitude of 37,000 feet above sea level, then the slope is zero.

b) When the plane is descending at rate of 1000 feet per minute, then the slope is negative.

c) When the plane is ascending at a rate of 2000 feet per minute. then the slope is positive.

Répondre:

1 285 watts

Explication étape par étape:

La puissance est exprimée selon la formule;

power = travail effectué / temps

Puissance = Force * (distance / temps)

Depuis Vitesse = distance / temps

Puissance = Force * vitesse

Donné

Force = 2500N

Vitesse (en m / s) = 0,514 m / s

Obligatoire

Puissance

Remplacez la formule donnée;

Puissance = 2500 * 0,514

Puissance = 1,285Watts

Par conséquent, la puissance correspondante requise est de 1285 watts

Answer:

asd

Step-by-step explanation:

Answer:

a) The vertex will be at (-2, -1), and the parabola will look like a smiley face. 5 points on the parabola would be: (3, 24), (-3, 0), (2, 15), (-1, 0) and (1, 8).

b) The focus will be at (-2, 0), the directrix will be at y = -2, and the axis of symmetry will be at x = -2.

Step-by-step explanation:

a) The vertex (-2, -1) can be found by first setting the parentheses (x+2) equal to zero and solving to get the x value -2, then setting x equal to zero and solving to get the y value of -1.  

The parabola will be pointing up on both ends because the equation for it is positive (given 1 multiplied by parentheses) and it has a degree of 2.

The xy table to find the points would look like this:

x       |         y

3       |      24

-3       |        0

2       |       15

-1        |        0

1        |        8

b) The focus is one unit above the vertex, so the y value increases by 1. The directrix is a line 1 unit below the vertex, so its y value is 1 less than the vertex's. The axis of symmetry is the same as the x value of the vertex with infinite y values.

Answer:

Step-by-step explanation:

Slope means x there are many ways to find the slope like using the slope formula y2-y1/x2-x1  or using rise over run

Hope this help :)

Answer:

Rise over run

Step-by-step explanation:

So what the Rise is, is the point on which the line is persicly on point with they grid of your graph / how high also the distance on the  y axis. The run is the how far also known as the x axis.

so if we had a slope of 2/3

it would be a posative slope it wod go up 2 and to the right 3 to the next intersection of the y ad the x axis'

Multiplicative identity is the property shown by this equation

Step-by-step explanation:

Multiplicative identity is explained as the product of any number and one is that number. Multiplicative identity is a property exhibited by most of the mathematical tools.

Zero and one are the numbers used to simplify equations whereas zero is called the additive identity. If we add any number with zero, it will result in the same in number.

Like that 1 is used in multiplicative identity.  More simple example could be  5 ˣ 1 = 5 ., it is the multiplicative identity  property
