Find the fractional side lengths of a rectangle that has a perimeter of 64 5/6 inches.

The graph of an inverse trigonometric function passes through the point (1, pi/2). Which of the following could be the equation

rodikova [14]

Answer: C) $y=sin^-1 x$

Step-by-step explanation:

Since, the graph of an inverse trigonometric function will pass through the point $(1,\frac{\pi}{2})$ ,

If this point satisfies the function,

For the function $y=cos^{-1} x$

If x = 1

$y=cos^{-1}1=0$

Thus, $(1,\frac{\pi}{2})$ is not satisfying function $y=cos^{-1} x$ ,

⇒ The graph of $y=cos^{-1} x$ is not passing through the point $(1,\frac{\pi}{2})$

For the function $y=cot^{-1}x$

If x = 1

$y=cot^{-1}1=\frac{\pi}{4}$

Thus, $(1,\frac{\pi}{2})$ is not satisfying function $y=cot^{-1}x$ ,

⇒ The graph of $y=cot^{-1}x$ is not passing through the point $(1,\frac{\pi}{2})$

For the function $y=sin^{-1} x$

If x = 1

$y=sin^{-1}1=\frac{\pi}{2}$

Thus, $(1,\frac{\pi}{2})$ is satisfying function $y=sin^{-1} x$ ,

⇒ The graph of $y=sin^{-1} x$ is passing through the point $(1,\frac{\pi}{2})$ .

For the function $y=tan^{-1}x$

If x = 1

$y=tan^{-1}1=\frac{\pi}{4}$

Thus, $(1,\frac{\pi}{2})$ is not satisfying function $y=cos^{-1} x$ ,

⇒ The graph of $y=tan^{-1} x$ is not passing through the point $(1,\frac{\pi}{2})$ .

Hence, Option C is correct.

BIG POINTS! Please help me with this math problem. By the way, the answer is not 1 / 128 .

vodomira [7]

Answer and Step-by-step explanation:

2 * 2 * 2 * 2 * 2 * 2 * 2 = 128

2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 = 1024

4 * 4 * 4 * 4 * 4 = 1024

8 * 8 = 64

$\frac{128 - 1024}{1024 - 64}$

$\frac{-896}{960}$

896 and 960 both have 64 in common.

896 divided by 64 equals 14.

960 divided by 64 equals 15.

$-\frac{14}{15}$ is the answer.

Question 4 of 25

Ronch [10]

Answer:

The answer is B

Step-by-step explanation:

As polynomial means "many".

So, the power of expression must be greater than 1 (e.g. x², x⁵, x⁷)

Use the Factor Theorem to determine if the given binomial is a factor of the given polynomial function:f(x)=4x^4-20x^3+33x^2-22x

Xelga [282]

Answer:

D: f(5/2)=0; yes, the binomial is a factor of the polynomial

Step-by-step explanation:

The easy way to determine is to plug in the potential zero into the polynomial given the binomial divisor and see if it results in 0. If so, then the binomial is a factor of the polynomial:

Because f(5/2)=0, then the binomial is indeed a factor of the polynomial!
