200:22, 400:44, so there are 6 more marked deers left. To find them, 200/22, 9.09090909....., so 9.09090909*50 = 454.54545454 (round that and you get 455, hence the answer would be C).

CALCULUS EXPERT WANTED. Can someone solve this or at least try to explain to me the fundamental theorem of calculus (FTC).

Amanda [17]

a. By the FTC,

$\displaystyle\frac{\mathrm d}{\mathrm dx}\int_1^{\cos x}(t+\sqrt t)\,\mathrm dt=(\cos x+\sqrt{\cos x})\dfrac{\mathrm d}{\mathrm dx}\cos x=-\sin x(\cos x+\sqrt{\cos x})$

b. We can either evaluate the integral directly, or take the integral of the previous result. With the first method, we get

$\displaystyle\int_1^{\cos x}(t+\sqrt t)\,\mathrm dt=\dfrac{t^2}2+\dfrac{2t^{3/2}}3\bigg|_{t=1}^{t=\cos x}=\left(\dfrac{\cos^2x}2+\dfrac{2(\cos x)^{3/2}}3\right)-\left(\dfrac12+\dfrac23\right)$

$=\dfrac{\cos^2x}2+\dfrac{2\sqrt{\cos^3x}}3-\dfrac76$

c. The derivative of the previous result is

$\dfrac{2\cos x(-\sin x)}2+\dfrac{2\cdot\frac32(\cos x)^{1/2}(-\sin x)}3=-\sin x\cos x-\sin x\sqrt{\cos x}$

which is the same as the answer given in part (a), so ...

d. ... yes

Suppose the equation for line a is given by 2x-5y=15. If line a and b are parallel and the point (-10, 3) lies on line b, then w

Step2247 [10]

Answer:

Line $b$ is represented by the equation $y = \frac{2}{5}\cdot x + 7$ .

Step-by-step explanation:

Let be line $a$ represented by $2\cdot x - 5\cdot y = 15$ , whose explicitive form is:

$5\cdot y = 2\cdot x - 15$

$y = \frac{2}{5}\cdot x - 3$

As line $b$ is parallel to line $a$ , its slope is equal to $\frac{2}{5}$ . Two lines that are parallel to each other have the same slope but different y-intercept. In addition, we know that point (-10, 3) lies on that line and we must find the y-intercept ( $k$ ):
