640 = x \times 10 \times 4

640 = 40x

Divide both sides by 40

\frac{640}{40}  =  \frac{40x}{40}  \\

x = 16

Thus the height would be 16 feet .

(a) Find the slope of the curve y= x^2 - 2x - 3 at the point ​P(2​,​ -3) by finding the limit of the secant slopes through point
gayaneshka [121]

Answer:

Step-by-step explanation:

P=(2,-3)

Q=(a,a²-2a-3)

\Delta y=a^2-2a-3-(-3)=a^2-2a\\\Delta x=a-2\\\\\displaystyle \lim_{a \to 2} \dfrac{a^2-2a-3-(-3)}{a-2}  \\\\=\lim_{a \to 2} \dfrac{a^2-2a}{a-2}  \\\\=\lim_{a \to 2} \dfrac{a(a-2)}{a-2}  \\\\=\lim_{a \to 2} \dfrac{a}{1}  \\\\=\lim_{a \to 2} a  \\\\=2\\

Proof:

y'=(x²-2x-3)'=2x-2

y'(2)=2*2-2=2

Area of triangle formula:

A = b*h/2

B is 18 and h is 13

B is base and h is height.

18 * 13 is 234.

We must divide by two because just multiplying the two numbers would result in an area of a square, divide by 2 for a triangle.

234/2 =
