Hey there! I'm happy to help!
28(5280)=147840 feet per hour.
There are 60 minutes in an hour. To find out how many feet Bolt runs in a second we divide by 60.
147840/60=2464
And we divide by sixty again to get to seconds.
2464/60=41 1/15 feet per second.
Have a wonderful day! :D
I have to assume that you mean it is a similar rectangle, since a triangle can not be similar to a rectangle. In that case the original measurements are 4x4.5.
By doubling them, you get a rectangle with the measurements of 8x9 and thus the area is 72
The enthalpy change (ΔH) for the reaction given the data from the question is –900.8 KJ
<h3>Data obtained from the question</h3>
- 4NH₃ + 5O₂ —> 6H₂O + 4NO
- Enthalpy of ammonia, NH₃ = –46.2 KJ
- Enthalpy of Oxygen = 0 KJ
- Enthalpy of water, H₂O = –241.8 KJ
- Enthalpy of nitric oxide, NO = 91.3 KJ
- Enthalpy change (ΔH) =?
<h3>How to determine the enthalpy change</h3>
ΔHrxn = ∑ΔH(products) - ∑ΔH(reactants)
ΔHrxn = ∑[H(H₂O) + H(NO)] - ∑[H(NH₃) + H(O₂)]
ΔHrxn = [(6 × –241.8) + (4 × 91.3)] – [(4 × –46.2) + (5×0)]
ΔHrxn = –1085.6 + 184.8
ΔHrxn = –900.8 KJ

The <em><u>correct answers</u></em> are:
Part A: The slope of f(x) is greater; and Part B: The y-intercept of f(x) is greater.
Explanation:
To find the slope of f(x), we use the slope formula:
The slope of g(x) is found in the form the function is written in, slope-intercept form; y=mx+b, where m is the slope and b is the y-intercept. This means the slope of g(x) is 3. Since the slope of f(x) is 8, the slope of f(x) is larger.
The y-intercept is the point where the data crosses the y-axis. This means it will have an x-coordinate of 0. The point in the table for f(x) with an x-coordinate of 0 is (0, -1). This is the y-intercept of f(x).
The y-intercept of g(x) is b in the equation form y=mx+b. For g(x), the y-intercept is -2. -1 is greater than -2, so the y-intercept of f(x) is larger.
Answer:
we thus have enough informnation to prove that the two triangles are congruent. Because of thism, one side of the triangles, Pm which is the congruent side to that of PQ must be equal as well and
PM = QM
Step-by-step explanation:
because it's a parrallelogram, Ad = BC and AB = DC.
P passes through both AB and DC on a diagonal, angles created by P have oppoiste exterior angles of eachother.
the diagonals of AC create congruent angles at DMC and AMB and because P is cutting through them, the angles P cuts at DMQ and QMC are equal to that of AMP and PMB
that being said, we now see that the angles of APM triangle and AMC triangol are equal and because the diagonal of BD is is being cut by AC, which AD is parralel to BC and AB to Dc, we know now that lines AM and MC are congruent
we thus have enough informnation to prove that the two triangles are congruent. Because of thism, one side of the triangles, Pm which is the congruent side to that of PQ must be equal as well and
thus PM = QM
