Cole said that 555 rounded to the nearest ten is 600. What's coles error?

ki77a [65]

Cole's mistake was that he rounded 555 to the nearest hundred instead of the nearest ten. He should've rounded it to 560 because the tens place is the second number, not the first one.

Given the quadrant of theta in standard position and a trigonometric function value of theta , find the exact value for the indi

SVETLANKA909090 [29]

Answer:

$\sqrt{15}$

Step-by-step explanation:

$\cos(\theta)=\frac{1}{4}$ is given.

My attempt will to be to use the Pythagorean Identity:

$\cos^2(\theta)+\sin^2(\theta)=1$

$(\frac{1}{4})^2+\sin^2(\theta)=1$

$\frac{1}{16}+\sin^2(\theta)=1$

Subtract 1/16 on both sides:

$\sin^2(\theta)=\frac{15}{16}$

We have the following quotient identity:

$\frac{\sin^2(\theta)}{\cos^2(\theta)}=\tan^2(\theta)$

$\frac{\sin^2(\theta)}{\cos^2(\theta)}=\frac{\frac{15}{16}}{\frac{1}{16}}$

Multiply the numerator and denominator by 16. This is multiplying the fraction by 1 so this doesn't change the value of the fraction.

$\tan^2(\theta)=\frac{15}{1}$

$\tan^2(\theta)=15$

Square root both sides:

$\tan(\theta)=\pm \sqrt{15}$

Since we are in the first quadrant then all 6 trigonometric functions are positive there so the answer is $\sqrt{15}$ .

The multiplicative rate of change of the function f(x) = 2 × 5ˣ is 5.

<h3>What is Exponential Function?</h3>

An exponential function is a type of function in math that involves exponents. A basic exponential function is of the form f(x) = bˣ, where b > 0 and b ≠ 1.

The function is given as:

f(x) = 2 X 5ˣ

The above function is an exponential function.

An exponential function is represented as:

f(x) = abˣ

Where b represents the multiplicative rate

By comparison;

b = 5

Thus, the multiplicative rate of change of the function is 5.
