Answer:

Add 4K to both sides of the equation

Step-by-step explanation:

The goal is to isolate the variable.

What happens on one side of the equal sign must be done to the other like term on the other side of the equal sign.

k+6=-4k-9

To get rid of the 9 you must add 9 to its like term on the other side of the equation.

You shouldn’t add k to both sides of the equation because k is already positive and to cancel it out you must subtract k. (A variable has an inferred 1) (ex. 1k=k)

You also can’t subtract 4K from both sides of the equation because it is negative so the opposite of the negative would be to add the 4.

The only option that would be correct is the second one:

Add 4K to both sides of the equation because it will cancel out.

Answer:

z^ {8/5}

Step-by-step explanation:

$(z^{\frac{-4}{3})^{\frac{-6}{5} } \\We\ know\ that\ a^{(b)^c} = a^{bc}\\\\Hence, \\\\{z^{\frac{-4}{3})^{\frac{-6}{5}}\\}={z^{\frac{-4}{3}*\frac{-6}{5}\\}\\=z^{\frac{24}{15}}\\=z^\frac{8}{5}$

Which of the following describes the “p/2” in the expression above?

julia-pushkina [17]

Option B. Quotient is the right answer

Step-by-step explanation:

Given expression is:

p/2 +4(7+p)

Let us look at the options one by one

A. factor

p/2 is not a factor as the factor is always multiplied with another factor

B. quotient

This is the right answer as p is being divided by 2. The quotient of both will be used for further calculations

Hence,

Option B. Quotient is the right answer

From a point Q, the length of the tangent to a circle is 24 cm and the distance of Q from the centre is 25 cm find the radius of

Umnica [9.8K]

$\large\bold{{Question :}}$

From a point Q, the length of the tangent to a circle is 24 cm and the distance of Q from the centre is 25 cm find the radius of the circle.

$\large\bold\red{\underline{Solution :-}}$

Here, O is the center of the circle.

⟼ Given :

OQ = 25 cm
PQ = 24 cm

⟼ To Find : We have to find the radius OP.

Since QP is tangent, OP perpendicular to QP.

(Since, Tangent is Perpendicular to Radius ⠀⠀⠀⠀⠀⠀⠀at the point of contact)

So, ∠OPQ=90°

⟼ By Applying Pythagoras Theorem :

OP² + RQ² = OQ²

OP² + (24)² = (25)²

OP² = 625 - 576

OP² = 49

OP = √49

OP = 7 cm

Hence, The Radius is 7 cm
