Average rate of change = (f2 - f1) / (x2 - x1)

so

(15,605 - f(4)) / (6-4) = 7500
15,605 - f(4) = 2(7500)
15,605 - f(4) = 15,000
f(4) = 15,605 - 15,000
f(4) = 605

answer is last one. 605

Hello! I hope you are having a nice day. My name is Galaxy and I will be helping you today!

We can solve this problem in two steps, one being Comprehension and another being Solving. I'll start off with Comprehension.

Comprehension

We can see that based of the problem, for every batch of 7 kids, there are 4 boys and 3 girls. That means that we can split the total, which is 35, into groups of 7 and seeing how many girls and boys there are.

Now that we know what we need to figure out and what to do, we can begin solving.

Solving

So, for every group of 7 kids there are 4 boys and 3 girls. We can divide 35 by 7 to find how many of these identical groups there are.

$35 \div 7=5$

We know that there are 5 such groups of 4 boys and 3 girls each. Therefore, we can multiply 4 and 3 by 5 as there are 5 such groups to find our total.

$4*5=20\\$

We know there are 20 boys.

$3*5=15$

We know there are 15 girls.

We can check this by seeing if this adds up,

$15+20=35?\\35=35$

Therefore, our answer is there are 15 girls and 20 boys.

Suppose f(x, y) is a differentiable function of x and y and let g(r, s) = f (2rs, 8s − 2r). Use

worty [1.4K]

By the chain rule,

$\dfrac{\partial g}{\partial r} = \dfrac{\partial f}{\partial r} \\\\ ~~~~~ = \dfrac{\partial f}{\partial x} \dfrac{\partial x}{\partial r} + \dfrac{\partial f}{\partial y} \dfrac{\partial y}{\partial r} \\\\ ~~~~~ = 2 s \dfrac{\partial f}{\partial x} - 2 \dfrac{\partial f}{\partial y}$

where $x(r,s)=2rs$ and $y(r,s)=8s-2r$ .

If $r=2$ and $s=1$ , then

$x = 2\cdot2\cdot1 = 4$

$y=8\cdot1-2\cdot2 = 4$

so that

$g_r(2,1) = 2\cdot1 f_x(4,4) - 2 f_y(4,4) = 2\cdot2-2\cdot3 = \boxed{-2}$

Which expression is equivalent to -2 1/4÷ (-2/3)

Talja [164]

Answer:

$-2\dfrac{1}{4}\div\left(-\dfrac{2}{3}\right)=\dfrac{27}{8}=3\dfrac{3}{8}}$

Step-by-step explanation:

$-2\dfrac{1}{4}\div\left(-\dfrac{2}{3}\right)\qquad\text{the quotient of two negative numbers is positive}\\\\=2\dfrac{1}{4}\div\dfrac{2}{3}\qquad\text{convert the mixed number to the improper fraction}\\\\=\dfrac{2\cdot4+1}{4}\div\dfrac{2}{3}=\dfrac{9}{4}\div\dfrac{2}{3}\\\\\text{dividing by a fraction is the same as multiplying by its reciprocal.}\\\\=\dfrac{9}{4}\cdot\dfrac{3}{2}=\dfrac{9\cdot3}{4\cdot2}=\dfrac{27}{8}\qquad\text{convert to the mixed number}\\\\=3\dfrac{3}{8}$
