Oliver drives 45 miles per hour. Write an expression that represents the distance in miles he will travel for h hours driven

Answer:

The expression that represents the distance in miles Oliver will travel for h hours is: d=45\times h.

Step-by-step explanation:

The first thing to take into account is the speed equation. It is , where v is the speed, x is the distance and t is the time.

Now, let's change the name of the variables to adapt the equation to the problem. The equation could be converted to:

, where v is the speed in miles per hour, d is the distance in miles and h is the time in hours.

The next step is to manipulate a little bit the previous equation to find the distance in terms of speed (v) and time (h). If you pass the variable time (h) to multiply to the left side with speed (v), the equation would be:

The previous equation is the distance in miles in terms of speed in miles per hour and time in hours. Now, you must replace the value of the speed that is 45 miles per hour. The expression would be:

As the speed is in miles per hour and the time is in hours, the distance expression is in miles. So if you replace any value for h (in hours), you will obtain the distance in miles.

Thus, the expression that represents the distance in miles Oliver will travel for h hours is: d = 45 x h.

H(x) = (x2 − 49)(x + 4)
Maru [420]

Answer:

h(x) = x³ + 4x² - 49x - 196

Step-by-step explanation:

h(x) = (x² - 49)(x + 4) <== distribute

h(x) = x²(x) - 49(x) + x²(4) - 49(4)

h(x) = x³ - 49x + 4x² - 196 <== rewrite in standard form (descending degrees)

h(x) = x³ + 4x² - 49x - 196

Hope this helps!

The position, x, of an object is given by the equation x = A + Bt +Ct2, where t refers to time. What are the dimensions of A, B,
Serjik [45]

Answer: Dimensions of A are of length [L]

Dimensions of B are of LT^{-1}

Dimensions of C are of LT^{-2}

Step-by-step explanation:

The given equation is

x(t)=A+Bt+Ct^{2}

Since the dimension on the L.H.S of the equation is [L] , each of the terms on the right hand side should also have dimension of length[L] to be dimensionally valid

Thus

Dimensions of A = [L]

Dimensions of Bt = [L]

Bt=[L]\\\\[B][T]=[L]\\\\\therefore [B]=LT^{-1}

Similarly

Dimensions of Ct^{}2 = [L]

Ct^{2}=[L]\\\\[C][T]^{2}=[L]\\\\\therefore [C]=LT^{-2}

MatroZZZ [7]

Answer:

B.

General Formulas and Concepts:

  • Order of Operations: BPEMDAS
  • Equality Properties

Step-by-step explanation:

<u>Step 1: Define function</u>

f(x) = 8x + 4

<u>Step 2: Prep</u>

  1. Rewrite:                         y = 8x + 4
  2. Swap <em>x</em> and <em>y</em>:               x = 8y + 4

<u>Step 3: Find Inverse (Solve for </u><em><u>y</u></em><u>)</u>

  1. Subtract 4 on both sides:                    x - 4 = 8y
  2. Divide both sides by 8:                       (x - 4)/8 = y
  3. Rewrite:                                                 y = (x - 4)/8
  4. Rewrite:                                                f⁻¹(x) = (x - 4)/8
