Answer:

- 1 and 15

Step-by-step explanation:

Substitute x = 2 and x = - 2 into f(x)

f(2) = - 4(2) + 7 = - 8 + 7 = - 1

f(- 2) = - 4(- 2) + 7 = 8 + 7 = 15

Answer:

[tex]f(x)=(x-1)^{2}+6[/tex]

Step-by-step explanation:

First, subtract 7 from each side.

[tex]-7=x^{2} -2x[/tex]

Now, add in a blank on each side so you can write in your new term that will complete the square. We'll call that term 's' for now.

[tex]-7+s=x^{2} -2x+ s[/tex]

The next step is to take half of the b term, and then square that. In this case, half of '[tex]-2[/tex]' is [tex]-1[/tex]. If we square that we get [tex]1[/tex]. So that is the term we will put in for [tex]s[/tex].

[tex]-7+1=x^{2} -2x+1[/tex]

Simplify:

[tex]-6=x^{2} -2x+1[/tex]

If you look at the right side of the equation, we can factor. That's because we completed the square. We can use the 'guess and check' method to factor. Remember, this is where we use 2 sets of parentheses and fill in the blanks.

[tex]-6=(x-1)(x-1)[/tex]

If we were to FOIL the right side we would end up with [tex]x^{2} -2x+1[/tex].  

Since we have 2 '(x-1)' terms next to each other, we can simplify to:

[tex]-6=(x-1)^{2}[/tex]

Now, all we need to do is add 6 to both sides and we have the vertex form.

[tex]f(x)=(x-1)^{2}+6[/tex]

I hope this helps!

Answer:

  A) d/900 +14 +d/540 = 16

  B) 675 feet

Step-by-step explanation:

A) The times are all given in minutes, so it is convenient to use units of feet and minutes in this problem. There are 60 seconds in a minute, so the bee's speeds can be rewritten as ...

  15 ft/s = (15 ft/s)(60 s/min) = 900 ft/min

  9 ft/s = (9 ft/s)(60 s/min) = 540 ft/min

We know that time is the ratio of distance to speed, so for distance d, we have a total time of ...

  d/900 +14 +d/540 = 16

B) To solve the equation, we can subtract 14, then combine the fractions. Here, we choose to combine the fractions in a straightforward way, not being too concerned about "least common denominator." We use the formula ...

  a/b + c/d = (ad +bc)/(bd)

  (540d +900d)/(900·540) = 2 . . . . subtract 14, combine fractions

  d = 2(900)(540)/(1440) = 675

Step-by-step explanation:

Answer:

3(34) + 20 -> Angle 6 = 122

2(34) - 10 -> Angle 3 = 58

Step-by-step explanation:

Since measure of angle 2 is equal to measure of angle 6, and measure of angle 7 is equal to measure of angle 3, we can determine the angle measures for angle 3 and angle 6.

First, we solve for x by adding together the two equations and setting it equal to 180 because of the supplementary angles theorem.

3x + 20 + 2x - 10 = 180

Combine like terms.

5x + 10 = 180

Subtract 10, then divide by 5 on both sides.

5x = 170

x = 34

Now we can plug the x value into the equations.

3(34) + 20 -> Angle 6 = 122

2(34) - 10 -> Angle 3 = 58

Answer:

P₂  = [tex]\frac{P_{1} V_{1} }{V_{2} }[/tex]  

Step-by-step explanation:

Given expression:

     Boyle's law:

             P₁ V₁   = P₂ V₂

Problem is to find P₂;

Solution:

              P₁ V₁   = P₂ V₂

 To solve this problem, multiply both sides by [tex]\frac{1}{V_{2} }[/tex];

   P₁ V₁  x   [tex]\frac{1}{V_{2} }[/tex]; = P₂ V₂  x  [tex]\frac{1}{V_{2} }[/tex];

     [tex]\frac{1}{V_{2} }[/tex] cancels out V₂ on the right hand side;

              P₂  = [tex]\frac{P_{1} V_{1} }{V_{2} }[/tex]

Answer:

Average rate of change = 0.4

Step-by-step explanation:

Average rate of change of a function in the interval [a, b] is defined by the formula,

Rate of change = [tex]\frac{f(b)-f(a)}{b-a}[/tex]

From the table attached,

Rate of change of the function in the interval 20 ≤ x ≤ 40 will be

= [tex]\frac{f(40)-f(20)}{40-20}[/tex]

= [tex]\frac{24-16}{40-20}[/tex]

= [tex]\frac{8}{20}[/tex]

= [tex]\frac{2}{5}[/tex]

= 0.4

Therefore, average rate change of the function in the given interval 20 ≤ x ≤ 40 is = 0.4

Answer:

1.5 miles

Step-by-step explanation:

Since Joan need to run 5 miles without stopping and already runs 3.5 miles without stopping, the number of miles more she must run non-stop to achieve her goal of 5 miles without stopping is the difference between her 5 mile goal and her current run of 3.5 miles.

So, number of miles she must run = 5 miles - 3.5 miles = 1.5 miles.

So, Joan must run 1.5 miles more non-stop to achieve her goal.

Answer:

w =2.5

Step-by-step explanation:

the area of the triangle is 6*5 divided by half which is 15. this means that the area of the rectangle is also 15. so to find the value of the width we have to divide the area by the known value to get our answer. 15/6 is equal to 2.5 so that's what the value of w is.
