Find the length please help

El área de un rectángulo se calcula multiplicando la longitud de la base por la longitud de la altura. La base del rectángulo mi

NemiM [27]

Answer:

the height of the rectangle is 13 cm

Step-by-step explanation:

The computation of the height of the rectangle is shown below:

As we know that

Area of rectangle = base × height

156 cm^2 = × 12 × height

So, the height is

= 156 ÷ 12

= 13 cm

hence, the height of the rectangle is 13 cm

Please Help Quickly!!!<br><br> Find the limit if f(x) = x^3

jeka94

Answer:

Option b. 12

Step-by-step explanation:

This exercise asks us to find the derivative of a function using the definition of a derivative.

Our function is $f(x) = x^{3}$ . Therefore:

$f(2+h) = (2+h)^{3}$

$f(2) = (2)^{3} = 8$

Then:

$\lim_{h \to \0} \frac{f(2+h)-f(2)}{h}=\lim_{h \to \0} \frac{(2+h)^{3}-8}{h}$

Expanding:

$\lim_{h \to \0} \frac{(2+h)^{3}-8}{h} =\lim_{h \to \0} \frac{8+ h^{3} +6h(2+h) -8}{h} =\lim_{h \to \0} \frac{h^{3} +6h(2+h)}{h}$

$\lim_{h \to \0} \frac{h^{3}+ 6h(2+h)}{h} =\lim_{h \to \0} h^{2} + 6(2+h)$

Now, if x=0:

$\lim_{h \to \0} \frac{f(2+h)-f(2)}{h} = (0)^{2} +6(2+0) = 12$

A silk worm wind ts cocoon out of one long silk fiber. to make silk thread, 3 to 10 of these silk fibers are unwound from their

In-s [12.5K]

Answer: There would be about 6 or 7 silk fibers per 300 yard length of silk fiber.

The problem states that each thread is made of about 3 to 10 silk fibers. The the problem as for a reasonable estimation of the number of silk fibers. It would be safe to assume that a reasonable estimation would be the average (or mean) of 3 to 10.

(3 + 10) / 2 = 6.5

Since 6.5 is the average, we could use 6 or 7 as a reasonable estimation.

Answer:

Option (C)

Step-by-step explanation:

From the picture attached,

Two lines 'h' and 'k' are the parallel lines and a transversal 'n' is intersecting these parallel lines at two distinct points.

By the theorem of alternate interior angles, angle 8 and angle 11 will be equal in measure.

∠8 ≅ ∠11 [Alternate interior angles]

m(∠8) = m(∠11) = 118°

Therefore, Option (C) will be the answer.
