It has to be either the first option or the last option because when u see variables it will usually be all of the letters so if your looking for a quick answer its probably the last option

Answer:

The answer is " $\frac{72}{4} =18$ ".

Step-by-step explanation:

Given value:

4 40 32

Solution:

${\boxed{4\ \boxed{40} \ \boxed{32}}}$

If we divide the value by 4 it will give 10 and 8.

$\to \frac{40}{ 4} = 10\\\\\to \frac{32}{ 4} = 8\\$

If we add the boxed value it will be equal to 72 and divide the value by 4 it will give a value 18.

$\to 40+32 =72\\\\\to \frac{72}{4}=18$

A point moves along the curve y = √ x in such a way that the y-component of the position of the point is increasing at a rate of

Eduardwww [97]

Answer:

The value of x component changes at a rate of $\frac{dx}{dt}=4\sqrt{x}$ units per second

Step-by-step explanation:

We are given that $y=x^{\frac{1}{2}}$

Differentiating on both sides with respect to time we get

$\frac{dy}{dt}=\frac{d\sqrt{x}}{dt}\\\\\frac{dy}{dt}=\frac{1}{2}x^{\frac{-1}{2}}(\frac{dx}{dt})\\\\\frac{dy}{dt}=\frac{1}{2\sqrt{x}}\frac{dx}{dt}$

It is given that $\frac{dy}{dt}=2units/sec$

Solving for $\frac{dx}{dt}$ we get

$\frac{dx}{dt}=\frac{dy}{dt}\times 2\sqrt{x}\\\\\frac{dx}{dt}=4\sqrt{x}$

The cost of five shirts and three pairs of pants is $229.25. If one pair of pants costs $37.25, what is the cost of one shirt? (

katen-ka-za [31]

3 x $37.25 = $111.75
$229.25 - $111.75 = $117.50
$117.50 ÷ 5 = $23.50
So the answer is B
