Consider the function f(x) =

Luden [163]

Answer:

It's B

Step-by-step explanation:

B) Because Limit as x approaches negative 1 f(x) = –4 and f(–1) = –4, it follows that Limit as x approaches negative 1 f(x)= f(–1). Therefore, the function is continuous at x = –1

Answer:

9 × (1 × 4) = (9 × 1) × 4

Step-by-step explanation:

Number 3 because the associative property states that it doesn't matter how you add / multiply something in sets.

9 × (1 × 4) = (9 × 1) × 4 shows 9 × 1 × 4 in 2 ways with 2 sets.

Please help!!

Annette [7]

Answer:

Both

Kinetic energy is 25 joule

Potential energy is 784.8 joule

Step-by-step explanation:

Given : A 2-kg bowling ball rolls at a speed of 5 m/s on the roof of the building that is 40 tall.

To find : Is it KE or GPE or Both

Solution :

Mass of the ball - 2 kg

Velocity of the ball - 5 m/s

Height - 40 tall

Both the energy is applied on the object.

1) Kinetic energy (KE)

Formula to find KE is $KE=\frac{1}{2}mv^2$

$KE=\frac{1}{2}(2)(5)^2$

$KE=25$

Kinetic energy is 25 joule.

2) Potential energy (GPE)

Formula to find GPE is $PE=mgh$

g is the acceleration due to gravity, $g=9.81 m/s^2$

$PE=(2)(9.81)(40)$

$PE=784.8$

Potential energy is 784.8 joule.

A grain silo is approximately 85% full. A 55 lb sack of grain measures 2 cubic feet.

erastova [34]

Answer:

Option A . 1708 bags

Step-by-step explanation:

The picture of the question in the attached figure

step 1

Find the volume of the silo

The volume of the silo is equal to the volume of a cylinder plus the volume of a cone

$V=\pi r^{2}h_1+\frac{1}{3}\pi r^{2}h_2$

we have

$\pi =3.14$

$r=16/2=8\ ft$ ---> the radius is half the diameter

$h_1=16\ ft$

$h_2=12\ ft$

substitute

$V=(3.14)(8)^{2}(16)+\frac{1}{3}(3.14)(8)^{2}(12)$

$V=3,215.36+803.84=4,019.2\ ft^3$

Remember that

The silo is approximately 85% full

The volume of grain in the silo is

$0.85(4,019.2)=3,416.32\ ft^3$

step 2

Find the number of bags of grain

Divide the volume of grain in the silo by the volume of one sack

$3,416.32/2=1,708\ bags$
