How to find all possible functions with the given derivative ? If
Gre4nikov [31]

Answer:

a) y = -\frac{1}{7}\cdot \cos 7\cdot t + C, b) y = -\frac{1}{7}\cdot \cos 7\cdot t + 7\cdot \sin \left(\frac{t}{7}\right) + C.

Step-by-step explanation:

a) The antiderivative of y' = \sin 7\cdot t is:

y = -\frac{1}{7}\cdot \cos 7\cdot t + C

b) The antiderivative of y' = \sin 7\cdot t + \cos \left(\frac{t}{7}\right) is:

y = -\frac{1}{7}\cdot \cos 7\cdot t + 7\cdot \sin \left(\frac{t}{7}\right) + C

Answer:To find the area of a circle with the radius, square the radius, or multiply it by itself. Then, multiply the squared radius by pi, or 3.14, to get the area. To find the area with the diameter, simply divide the diameter by 2, plug it into the radius formula, and solve as before

The hypotenuse of a right triangle measures 16 cm and one of its legs measures 9 cm. Find the measure of the other leg. If neces
Vesnalui [34]

\sf\huge\underline{\star Solution:-}

<h3><u>Given that</u>:</h3>
  • Hypotenuse of a right triangle = \sf\blue{16cm.}
  • One side (leg) = \sf\blue{9cm.}

<h3><u>To Find</u>:</h3>
  • Measure of another side(leg).

<h3><u>Solution</u>:-</h3>

\rightarrow As we know that,

\sf{A^2 +B^2 \:=\: C^2}(Pythagoras Theorem)

So, using this formula we can find measure of another side(leg).

\rightarrow\sf{A^2 +B^2 \:=\: C^2}(putting the value of both given side of triangle)

  • Here I am putting the value of hypotenuse in C because it is the longest side of triangle.

\rightarrow \sf{9^2 +B^2 \:=\: 16^2}

\rightarrow \sf{81 +B^2 \:=\: 256}

\rightarrow \sf{B^2 \:=\: 256-81}

\rightarrow \sf{B^2 \:=\: 175}

\rightarrow \sf{B \:=\: \sqrt{175}}

\rightarrow \sf{B\:=\: 13.22(approx)}

Therefore, measure of another side (leg) of the triangle = \sf\purple{ 13.22(approx).}
