What is the y-intercept of the function, y = 3x -5?

Answer:

\( \sin(x) = \frac{1}{4} \\ { \sin }^{2} x = \frac{1}{16} \\ { \cos } x = \sqrt{1 - { \sin }^{2}x } \\ \cos(x) = \sqrt{1 - \frac{1}{16} } \\ \cos(x) = \sqrt{ \frac{15}{16} } \\ \tan(x) = \frac{ \sin(x) }{ \cos(x) } \\ \tan(x) = \frac{ \frac{1}{4} }{ \sqrt{ \frac{15}{16} } } \\ \tan(x) = 0.258\)

The exact value of tan x is,

⇒ tan x = - 1/√15

A ratio indicates how many times one number contain in another number. The ratio of two number is written as x : y, which is equivalent to x/y.

Where, x and y are individual amount of two quantities.

And, Total quantity gives after combine as x + y.

First, we can use the fact that sin x = 1/4 to find the value of cos x.

We know that;

sin²x + cos²x = 1,

cos²x = 1 - sin²x

cos²x = 1 - (1/4)²

cos²x = 1 - 1/16

cos x = ±√(15/16)

But since we know that x is in the third quadrant , we know that cos x is negative.

Therefore, we can take:

cos x = -√(15/1`6)

Now we can use the fact that;

tan x = sin x / cos x

tan x = sin x / cos x

tan x = (1/4) / (-√(15/16))

tan x = - (1/4) * (4/√15)

tan x = - 1/√15

So, the exact value of tan x is,

⇒ tan x = - 1/√15

The price of one cubic yard of sand is $33.75, then the price of one cubic foot of sand should be  $1.25.

To determine the price of one cubic foot of sand, we need to convert cubic yards to cubic feet. One cubic yard is equal to 27 cubic feet (3 feet x 3 feet x 3 feet). Therefore, if the price of one cubic yard of sand is $33.75, then the price of one cubic foot of sand should be $33.75/27 = $1.25.

This makes sense because one cubic yard contains 27 cubic feet. So, if the price of one cubic yard is $33.75, then the price per cubic foot should be 1/27th of that price.

It is important to note that this assumes the price per unit of sand remains constant regardless of the quantity purchased. In reality, bulk purchases may result in a discounted price per unit. Additionally, factors such as transportation costs and demand may also affect the price of sand.

16 fl oz Vinegar

8 fl oz Water

The ratio of vinegar to water is 2:1, as you need 2 parts of vinegar for every 1 part of water.

Add these together to get 3, which is the proportion the ratio will be divided into.

Divide the total 24 fl oz by the group of 3, and you work out that each part of the ratio should be scaled up by 8.

Multiply each part of the ratio by 8 to get 8x2 : 8x1. The ratio of vinegar to water is now 16:8, so you need 16 fl oz of vinegar and 8 fl oz of water.

Answer:

16 fl oz vinegar, 8 fl oz water.

First, look at your ratio (2:1), and determine how many parts in total there would be. That, of course, is 3 (2 parts vinegar + 1 part water = 3 parts total). Then, divide the total 24 fl oz in the spray by this number to get the number of fl oz in each part of the bottle; with the equation, you should get 24 / 3 = 8 fl oz. Finally, multiply this two each part of the ratio: 2 parts x 8 fl oz = 16 fl oz of vinegar, 1 part x 8 fl oz = 8 oz of water.

When the figure is dilated by a scale factor of 3, the original coordinates of P are (1,2).

A coordinate system in geometry is a system that uses one or more numbers, or coordinates, to determine the position of points or other geometric elements on a manifold such as Euclidean space. The ordinate is the distance of a point from the x-axis scaled with the y-axis. Coordinates are the abscissa and ordinate combined. The study of algebraic equations on graphs is known as coordinate geometry. Plotting points, lines, and curves on an x and y axis is an example of coordinate geometry. Make corrections.

Here,

Answer:

y = x - 2

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

calculate m using the slope formula

m = \(\frac{y_{2}-y_{1} }{x_{2}-x_{1} }\)

with (x₁, y₁ ) = (0, - 2) and (x₂, y₂ ) = (2, 0) ← 2 points on the line

m = \(\frac{0-(-2)}{2-0}\) = \(\frac{0+2}{2}\) = \(\frac{2}{2}\) = 1

the line crosses the y- axis at (0, - 2 ) ⇒ c = - 2

y = x - 2 ← equation of line

Given function f(x) is as follows;f(x) = (916x³)/3 - 4x² + 6x - 13To find out the value of x for which the given function has a tangent line of slope 5, we need to use the concept of derivative. Since, the slope of the tangent line to the curve at a point on it is the value of the derivative at that point.

So, first we need to take the derivative of f(x). Differentiating the given function, we get;f'(x) = 916x² - 8x + 6Now, we need to find the value of x for which the slope of the tangent is equal to 5.We can form an equation by equating f'(x) to 5;916x² - 8x + 6 = 5Or, 916x² - 8x + 1 = 0.

We can solve the quadratic equation for x using quadratic formula  Therefore, the value(s) of x for which f(x) has a tangent line of slope 5 is (52/1832) or (-58/1832).

The seismograph reading of the earthquake is approximately 1.99526.To determine the seismograph reading of the earthquake with a magnitude of 3.3 on the Richter scale, we can use the formula M(I) = log(I/0.001), where M(I) represents the magnitude and I represents the intensity of the earthquake.

In this case, we are given the magnitude of 3.3. Let's substitute this value into the formula and solve for I:

3.3 = log(I/0.001)

To isolate I, we need to convert the equation into exponential form:

10^(3.3) = I/0.001

Simplifying the equation, we have:

I = 10^(3.3) * 0.001

Using a calculator, we find that 10^(3.3) is approximately 1995.26.

So, the seismograph reading of the earthquake is:

I = 1995.26 * 0.001

≈ 1.99526.
