docker41 [41]

Answer:

$\huge\boxed{(f-g)(x)=3x^2+6}$

Step-by-step explanation:

$(f-g)(x)=f(x)(x)\\\\\text{substitute}\ f(x)=4x^2+1\ \text{and}\ g(x)=x^2-5\\\\(f-g)(x)=(4x^2+1)-(x^2-5)=4x^2+1-x^2-(-5)=4x^2+1-x^2+5\\\\\text{combine like terms}\\\\(f-g)(x)=(4x^2-x^2)+(1+5)=3x^2+6$

The correct option is B.

What Is a Liberal Arts College?

While many colleges and universities grant liberal arts degrees, a liberal arts college offers a focused liberal arts education.
These colleges generally emphasize small class sizes and a curriculum centered on the humanities, arts, social sciences, and natural sciences.

What's the difference between a liberal arts college and a regular college?

Most liberal arts colleges do not offer graduate school programs, unlike other universities.
They also tend to have small campuses and class sizes; in fact, many classes have fewer than 20 students.
Evans says some students find comfort in the sense of community that these more intimate settings can create.

sergejj [24]

Answer:

Step-by-step explanation:

Using the formula

p +/- z* √(p(1-p) / n)

Where p is sample proportion = 3226/3957 = 0.8153, n = 3957 and z* is 2.576

0.8153 + (2.576 √(0.8153(1-0.8153) / 3957))

0.8153 + (2.576 √ (0.8153(0.1847) /3957)

0.8513 + (2.576 √(0.1572/3957)

0.8513 + (2.576 √0.00003974)

0.8513 + 2.576(0.0063)

0.8513 + 0.016

0.8670 ~ 87%

For the lower interview

0.8513 - 0.016

= 0.8353 ~ 84%

Thus, at 99% confidence interval is 84% and 87%

Motorbikes have two wheels and cars have four wheels. There are a number of

astra-53 [7]

Answer:

74 Cars

Step-by-step explanation:

If each motorbike has 2 wheels then we need to find how many wheels the motorbikes already take up.

We do this by doing 14*2 and we get 28 wheels.

Afterwards, we subtract this from the total of 324 to see how many wheels are left over. 324-28=296

Now we know the remaining amount of wheels and with this we can get our final answer!

Since there are 296 remaining wheels and each car takes up 4 we can divide 296 by 4 to see how many cars would be able to get their full set of tires.

296/4 = 74 and that;s how you get 74 cars!

A pyramid-shaped tent has a square base with sides that are 4 ft long. If the tent is 6 ft tall, what is the volume of the tent?

Dmitry_Shevchenko [17]

The volume of the tent would be 96ft^3, this is because the equation for volume is Length x Width x Hight, so (4)(4)(6) which makes 96
