Answer:

Charlotte is right; m=1/3

Step-by-step explanation:

On the graph, you can pick 2 points to find slope with slope formula:

(y2-y1)/x2-x1)

Two points we can choose from the graph are (0,0) and (1,3).

Now we plug these into our formula:

(1-0)/(3-0)

1/3

Answer: First option, “22”

Step-by-step explanation:

The possible values of the solutions to the equations are; (π/4, 7π/4)

We are given the equation;

sin(5x - π) = (√2)/2

Now, (√2)/2 is also expressed as 1/√2.

Thus;

sin(5x - π) = 1/√2

5x - π = sin⁻¹(1/√2)

5x - π = π/4

5x = π + π/4

5x = ⁵/₄π

Thus;

x = π/4

Now, since x < 2π, then it means it is in the fourth quadrant. Thus;

x = 7π/4

Answer:

6p =120

Step-by-step explanation:

well the p's are very close together in a sense that we are going to multiply instead of add because they the p's would have space in between

6 * 20 = 120

so p= 20

choose A

and P=20

6p is equal to 6×20

to get P, do 120÷6

Answer:

Tu recibiste = $1714,3  

Reiner recibió = $857,1

Julio recibió = $3428,6

Step-by-step explanation:

Podemos encontrar el dinero que recibieron todos mediante la siguiente expresión:

[tex] A + R + C = 6000 [/tex]

Dado que A recibió 2 veces más que el dinero que Reiner y C recibió 4 veces lo que recibió Reiner, entonces:

[tex] 2R + R + 4R = 6000 [/tex]

[tex] R = \frac{6000}{7} = 857,1 [/tex]

Ahora, podemos encontar cuanto recbieron los otros dos primos:

[tex] A = 2R = 2*\frac{6000}{7} = \frac{12000}{7} = 1714,3 [/tex]

[tex] C = 4R = 4*\frac{6000}{7} = \frac{24000}{7} = 3428,6 [/tex]

Por lo tanto, tu recibiste $1714,3, Reiner recibió $857,1 y Julio recibió $3428,6.

Answer:

121cm −25πcm ≈42.46cm

Step-by-step explanation:

First, calculate the area of the whole figure, including the unshaded area.

(The area of a rectangle is the length times the width.)

Next, calculate the area of the inner figure.

π×5cm×5cm=25πcm

Finally, subtract the area of the inner circle from the area of the outer rectangle.

Answer:

1200feet

Step-by-step explanation:

Given the the road's curve elevation modeled by the equation

y = 0.00005x^2 - 0.06x,

x is the horizontal distance in feet between the points where the road is at sea level and;

y is the elevation

The elevation the road is equal to sea level when y = 0

Substitute y = 0 into the equation and calculate x;

0 = 0.00005x^2 - 0.06x

0.06x = 0.00005x^2

0.06 = 0.00005x

x = 0.06/0.00005

x = 1200 ft

Hence they will place the stop sign at a horizontal distance of 1200feet

y= -2 +490

3

Step-by-step explanation:

y=mx+b is the slope intercept form of a like where m is the slope and b is the y intercept

Answer:

y=-2/3x+490

Step-by-step explanation:

As we know the formula for slope intercept form would be y=mx+b

therefore we arrange our numbers in the following manner:

First subtract 2x from 2x so it'll be like 2x-2x and they cancel each other out so keep that in mind, now what you do on one side you have to do it on the other side as well therefore you'll putt -2x on the other side now we are left our equation as 3y=1,470-2x

Second, as we want our form to be slope intercept form I believe that y should be by it self and to do that you need to divide 3 from y, now remember that what you do on one side you have to do it on the other. So you'll divide 3 from all the numbers on the other side. Now on the other side we have 1,470-2x so we will divide 1,470/3=490 and -2x/3 now we are left with y= 490-2/3x ( i left -2/3x as that because dividing makes it a decimal and a decimal and the fraction has the same value so I just left it as a fraction)

Thirdly, sense we want our equation as a slope intercept form we will need to rearange our equation which we need to keep in mind the form which is y=mx+b so that makes it to our answer y=-2/3x+490

Hope this helps :)

Answer:

The cost is a fixed $2, plus $3.25 for any additional hour.

Then if you rent it for x hours, the cost is:

c(x) = $2 + $3.25*x

Is this situation continuous or discrete?

Yes, it is discrete, because x is "the number of hours"

so if you rent it for 1.30 hours, they will say "ok, this is equivalent to two hours".

This means that while the values of x are continuous, the possible costs are:

{$2, $2 + $3.25, $2 + 2*$3.25, ....}

Which is a discrete set.

Then the sign for 1 to 5 hours will be:

1 hour ---------- $2 + $3.25 = $5.25

2 hours -------- $2 + 2*$3.25 = $8.50

3 hours--------- $2 + 3*$3.25 = $11.75

4 hours--------- $2 + 4*$3.25 =  $15

5 hours -------- $2 + 5*$3.25 = $18.25

In the other park the cost is only $4 for each hour (no fixed cost) then the total cost for x hours is:

c(x) = $4*x

Now, which option is better?

If we look at the costs for different numbers of hours for this other equation, we have:

1 hour ----- $4

2 hours ---- 2*$4 = $8

3 hours ----- 3*$4 = $12

4 hours ------ 4*$4 = $16

Then: if you want to skate 2 hours or less, Skate City is cheaper, if you want to skate more than that, kate Days is cheaper.

This happens because the first one has a smaller slope, meaning that is larger at first, but as x grows the price does not grow as much as in Skate City

Answer:

24 feet, 24 feet, 30 feet

Step-by-step explanation:

edge 2020

The given perimeter of 108 feet, and length of the longer side of 30 feet,

gives the following length of the other sides;

A kite has two pairs of adjacent sides having equal length

Let x represent the length of one of the shorter sides, we have;

Which gives;

x = (108 - 2 × 30) ÷ 2 = 24

The length of one of the short side, x = 24 feet

The kite has 2 sides of length 24 feet and 2 sides of length 30 feet

The lengths of the other sides are therefore;
