Find f(x) if it is known that f(x+3)=4x+12.
MArishka [77]

Solution:

we are given that

f(x+3)=4x+12

we have been asked to find f(x).

we can find the value of f(x) by re-writing the given function in the form of f(x+3) and thereafter we will replace (x+3) by x.

we can re-write the given function as below

f(x+3)=4(x+3)\\\\\Rightarrow f(x)=4x\\

Hence the expression representing f(x) is f(x)=4x+3.

Nina has prepared the following two-column proof below. She is given that ∠OLN ≅ ∠LNO and she is trying to prove that OL ≅ ON. S
Anit [1.1K]
Step number 3 should really be step number 7, it should be placed after step 4, 5, and 6. The reason is because we won't know that ∠LEO ≅ ∠NEO until after we learn that LE ≅ EN. Because of this, step 3 is in the wrong spot (mistake number one). The secod mistake is that step 7, triangle OLE ≅ triangle ONE is congruent by Angle-Side-Angle (ASA) Postulate, not Side-Angle-Side (SAS) Postulate. It is congruent by ASA because we know that both triangles have equal angles N and L. We also know that the perpendicular bisector creates a 90° angle. So m∠LEO = 90° and ∠NEO = 90°. Therefore, we already have 2 congruent angles in both of the triangles. We also learn that line LE ≅ EN based on the definition of a perpendicular bisector, so we have know one that one side of each triangle is congruent. It is ASA and not AAS, because the ASA Postulate states that two angles and one included side of one triangle are congruent to two angles and one included side of another triangle.

4. Han's younger sister is riding her tricycle in a straight line. After 3 s, her speed is 0.5 m/s. After 5 s, her speed is 1.5
liberstina [14]

Answer:

Han's younger sister accelerated at a rate of 0.5 meters per square second during that time.

Step-by-step explanation:

Let suppose that Han's younger sister accelerates at constant rate, then, acceleration (a), measured in meters per square second, can be calculated by the following equation:

a = \frac{v_{f}-v_{o}}{t_{f}-t_{o}}

Where:

t_{o}, t_{f} - Initial and final times, measured in seconds.

v_{o}, v_{f} - Initial and final speeds, measured in meters per second.

If we know that t_{o} = 3\,s, t_{f} = 5\,s, v_{o} = 0.5\,\frac{m}{s} and v_{f} = 1.5\,\frac{m}{s}, the acceleration of the younger sister is:

a = \frac{1.5\,\frac{m}{s}-0.5\,\frac{m}{s}  }{5\,s-3\,s}

a = 0.5\,\frac{m}{s^{2}}

Han's younger sister accelerated at a rate of 0.5 meters per square second during that time.
