Answer:

43.75 miles

Step-by-step explanation:

You divide the 35 by 4 and then just add it to the original distance of 35 miles. 35/4=8.75

8.75+35=43.75

Answer:

y=(2x^2+24x)+25

y=2x(x^2+12x)+25

y=2x(x^2+12x+36)+25-2x(36)

Y=2x(x+6)^2+25-72

Y=2x(X+6)^2-47

Step-by-step explanation:

sorry it was late

Answer: y=2(x+6)²-5

Step-by-step explanation: First you find the coefficient of x^2, which is 2, then take out 2 as a factor, 24/2 which will equal to 12. After that do 47 divided by 2  if you calculate that it will equal to 23.5.  y=2(x²-12+23.5)  y =2(x²-12x+23.5)

Next Step: Figure out the coefficient of x. To make it easier,look what is in front of x as you can see it is 12. Then you divide 12/2 which is 6. Then square 6, which is 36. Then you add and subtract 36. To write the first three terms as a square, you do ( x+6)^2. Then do -36 + 23.5 if you calculate that it will get you wil get -12.5 . Now that you have calculated that distribute 2, then do 2 times -12.5 which is -12.5. This is how it shoud look like y=2(x+6)² -12.5.

Answer:

Step-by-step explanation:

The missing reasons are Cofunction identity, Cosine difference identity, Cofunction identity, Cosine function is even and sine function is odd respectively.

Given:

The given expression is [tex]\sin (x-y)[/tex].

To find:

The justification for each step.

Explanation:

Cofunction identities:

[tex]\sin\left(\dfrac{\pi}{2}-x\right)=\cos x[/tex]

[tex]\cos\left(\dfrac{\pi}{2}-x\right)=\sin x[/tex]

Cosine difference identity:

[tex]\cos(x-y)=\cos x\cos y+\sin x\sin y[/tex]

Cosine function is even, so [tex]\cos(-x)=\cos x[/tex].

Sine function is odd, so [tex]\sin(-x)=-\sin x[/tex].

We have,

[tex]\sin (x-y)[/tex]

[tex]=\cos\left|\dfrac{\pi}{2}-(x-y)\right|[/tex]                                             Step 1: Cofunction identity

[tex]=\cos\left|\dfrac{\pi}{2}-x+y\right|[/tex]                                                 Step 2: Distributive property

[tex]=\cos\left|\left(\dfrac{\pi}{2}-x\right)+y\right|[/tex]                                            Step 3: Associative property

[tex]=\cos\left|\left(\dfrac{\pi}{2}-x\right)-(-y)\right|[/tex]                                        Step 4: Factoring out   

[tex]=\cos\left(\dfrac{\pi}{2}-x\right)\cos(-y)+\sin\left(\dfrac{\pi}{2}-x\right)\sin(-y)[/tex]       Step 5: Cosine difference identity

[tex]=\sin(x)\cos(-y)+\cos(x)\sin(-y)[/tex]                           Step 6: Cofunction identity

[tex]=\sin(x)\cos(y)-\cos(x)\sin(y)[/tex]                                Step 7: Cosine function is even, sine function is odd

Therefore, the missing reasons are Cofunction identity, Cosine difference identity, Cofunction identity, Cosine function is even, sine function is odd respectively.

Step-by-step explanation:

Sorry about not answering your question sooner, but here is your answer:

In order to get the answer, we have to subtract the original amount of money on the phone card by the amount left ver after the call:

15 - 6.72 = 8.28

Then, we divide this number by 0.18:

8.28 / 0.18 = 46

Step-by-step explanation:

Easy buddy...

[tex]5x - 15 = 3x + 7[/tex]

Subtract the sides of the equation plus 15

[tex]5x = 3x + 7 + 15[/tex]

[tex]5x = 3x + 22[/tex]

Subtract the sides of the equation minus 3x

[tex]5x - 3x = 22[/tex]

[tex]2x = 22[/tex]

Divided the sides of the equation by 2

[tex]x = \frac{22}{2} \\ [/tex]

[tex]x = 11[/tex]

Answer: range: 3, domain: 4

Step-by-step explanation:

the range of a problem is basically the difference between the smallest and the largest y value. the largest y value here is 6 and the smallest is 3, so 6-3 = 3 -> 3 is your range! now for domain: the domain of a problem is the difference between the smallest and largest x value. the largest x value is 2 and the smallest is -2, so 2 - -2 = 4 -> the domain is 4! hope this helped!
