<h2>Translating Sentences into Equations</h2>

A key part of this is recognizing certain words to change into operations or numbers:

  • <em>quotient</em> = divide
  • <em>three more</em> = add 3
  • <em>'a/the number' </em>= use a variable (in this case, it's <em>w</em>)

<h2>Solving the Question</h2>

We're given:

  • Three more than the quotient of a number and 7 equals 6
    ⇒ 'the quotient of a number and 7' tells us we divide <em>w</em> by 7:
  • Three more than \dfrac{w}{7} equals 6
    ⇒ 'three more than' means we add 3 to the fraction:
  • \dfrac{w}{7}+3 equals 6
  • \dfrac{w}{7}+3=6

<h2>Answer</h2>

\dfrac{w}{7}+3=6

Pls answer will get brainliest!!!
crimeas [40]
By using The half-angle formula

cos X/2 = ±√[(1 + cos X)/ 2]
But we have cos x=2/3
= ±√[(1 + 2/3)/ 2]
= ±√[(5/3 )/ 2]
= ±√[(5/5]
=±√1

Therefore answer is ±1

cos A/2 = ±√[(1 + cos A )/ 2]

A circle has a radius of \sqrt{13}√ ​13 ​ ​​ square root of, 13, end square root units and is centered at (-9.3,4.1)(−9.3,4.1)le
timofeeve [1]

Answer:  The equation of the circle is

x^2+y^2+18.6x-8.2y+90.3=0.

Step-by-step explanation:  We are given to write the equation of the circle with radius √13 units and center at the point (-9.3, 4.1).

We know that

the standard equation of a circle with radius r units and center at the point (h, k) is given by

(x-h)^2+(y-k)^2=r^2.

In the given circle,

radius, r = √13 units  and  center, (h, k) = (-9.3, 4.1).

Therefore, the equation of the circle will be

(x-(-9.3))^2+(y-4.1)^2=(\sqrt{13})^2\\\\\Rightarrow (x+9.3)^2+(y-4.1)^2=13\\\\\Rightarrow x^2+18.6y+86.49+y^2-8.2y+16.81=13\\\\\Rightarrow x^2+y^2+18.6x-8.2y+103.3=13\\\\\Rightarrow x^2+y^2+18.6x-8.2y+90.3=0.

Thus, the equation of the circle is

x^2+y^2+18.6x-8.2y+90.3=0.
