find the y-intercept of f(x) = 3x^2 + 6x

===================================================

Explanation:

The remainder theorem says that if we divide some polynomial p(x) over (x-k), then p(k) is the remainder.

The expression x+1 is the same as x-(-1). Comparing this to x-k shows k = -1.

So we'll need to evaluate p(-1)

To do so visually, draw a vertical line through -1 on the x axis. Make sure this vertical line crosses the blue curve at some point, which I'll call point A.

From point A, draw a horizontal line to the y axis. You should reach y = 3.

This is all shown in the diagram below.

In other words, the point (-1,3) is on the blue curve, and p(-1) = 3.

So the remainder is 3.

Step-by-step explanation:

What types of lines intersect and are coplanar?

Coplanar Lines

Three types of lines that are coplanar are parallel lines, perpendicular lines, and transversals. These all exist in a single plane, unlike skew lines (which exist in multiple planes). Any two lines in a plane must necessarily either be parallel or intersect.

Answer:

The function is strictly increasing on (0, π/2)

Step-by-step explanation:

We are given the function;

y = sin x

Let's find the derivative;

dy/dx = cos x

Now, Cos 0 = 1

Cos (π/4) = 1/√2

Cos (π/2) = 0

From the above, we can see that as x approaches 0 from (π/2), the value of (cos x) approaches 1. This means it's increasing from 0 to 1.

Thus, the function is strictly increasing on the interval (0, π/2)

Answer:

D. (0, pi/2)

Step-by-step explanation:

If you graph y=sin(X) (I used desmos) then you find that the graph is increasing from 0 to pi/2  :)

Answer: If you have three quarters, four dimes, and four pennies, you have $1.19, the largest amount of money in coins you could have without being able to make change for a dollar

[tex]4x - 2 + (2x + 4) = 2(6x + 7) \\ [/tex]

[tex]4x - 2 + 2x + 4 = 12x + 14[/tex]

Simplification

[tex]6x + 2 = 12x + 14[/tex]

Subtract sides 2

[tex]6x + 2 - 2 = 12x + 14 - 2[/tex]

Simplification

[tex]6x = 12x + 12[/tex]

Subtract sides -12x

[tex]6x - 12x = 12x - 12x + 12[/tex]

Simplification

[tex] - 6x = 12[/tex]

Divided sides by -6

[tex] \frac{ - 6}{ - 6}x = \frac{12}{ - 6} \\ [/tex]

[tex]x = - 2[/tex]

It is must be in the box buddy.

Answer:

A≈165553.09

Step-by-step explanation:

To the nearest cent, there would be $174,529.50 in Samuel's account after 17 years of continuous compounding at an interest rate of 6.7%.

The formula for calculating the amount of money in an account with continuous compounding is:

[tex]A = Pe^{(rt)}[/tex]

where:

A = the amount of money in the account after t years

P = the principal amount invested

r = the annual interest rate (as a decimal)

t = the time in years

e = Euler's number (approximately 2.71828)

Using this formula, we can calculate the amount of money in Samuel's account after 17 years as follows:

[tex]A = 53,000 \times e^{(0.067\times 17)[/tex]

A ≈ $174,529.50

Therefore, to the nearest cent, there would be $174,529.50 in Samuel's account after 17 years of continuous compounding at an interest rate of 6.7%.

i just put it in a calculator

Answer:

A) The second day

B) 9/16 inches

A) Elsa reached farther on the second day because -1/16 > -5/8

B) To calculate this we must first put both fractions above the same denominator. We can then subtract the smaller one from the bigger one:

-1/16 - (-10/16) = 9/16

Elsa reached 9/16 inches farther on the second day then she did on the first.

Step-by-step explanation:

The end behavior of the graph f(x) using limits are

[tex]\lim_{x \to -\infty} f(x) = -\infty[/tex]

and

[tex]\lim_{x \to \infty} f(x) = -\infty[/tex]

Option B is the correct answer.

We have,

From the graph,

As the x-value increases, the function y-values goes to -∞.

As the x-value decreases, the function y-values goes to -∞.

Now,

f(x) is the y-value.

The end behavior of the graph f(x) using limits can be represented as,

[tex]\lim_{x \to -\infty} f(x) = -\infty[/tex]

and

[tex]\lim_{x \to \infty} f(x) = -\infty[/tex]

Thus,

The end behavior of the graph f(x) using limits are

[tex]\lim_{x \to -\infty} f(x) = -\infty[/tex]

and

[tex]\lim_{x \to \infty} f(x) = -\infty[/tex]
