Answer:

815/99 (fraction); 8 23/99 (mixed number)

Step-by-step explanation:

the fraction for 0.23 repeating is 23/99

you add 8 in front of it

8 23/99 is the mixed number version

for the fraction version you must multiply 99 to 8 and then add it to 23

8 * 99 = 792

792 + 23 = 815

so

the fraction is 815/99

The solution of the equation −46x + 874 = 86 − x will be 17.51 which is that number.

The distribution of weights to the variables involved that establishes the equilibrium in the calculation is referred to as a result.

−46 times a number minus 19 is equal to 86 less than the number.

Let the number be x. Then the equation is given as,

−46(x − 19) = 86 − x

Simplify the equation, then we have

−46x + 874 = 86 − x

45x = 788

x = 788 / 45

x = 17.51

The solution of the equation −46x + 874 = 86 − x will be 17.51 which is that number.

The water pressure on the submerged object is given by d = P ÷ 64

Pressure is the force that is applied perpendicularly to the area across which it is applied to an object's surface (symbol: p or P).

Gauge pressure, frequently written gage pressure, is the measurement of pressure in proportion to the atmosphere.

Various units are used to express pressure.

The pound-force per square inch (psi), which is equivalent to one newton per square meter (N/m2) in the SI, is the standard unit of pressure in the imperial and American customary systems.

A unit of force is divided by a unit of area to arrive at some of these findings.

a. The given formula is is P=64d

or , d = P ÷ 64

b. at a pressure of 672

d = 672  ÷ 64

or, d = 10.5 feet

Therefore the pressure is 672 pounds per square foot at a depth of 10.5 feet.

Answer:   Triangle

Reason:

A circle that goes through all three vertices of a triangle is known as the circumcircle. Every triangle has such a circle, which is why we can inscribe a triangle inside a circle.

In the picture, There is graph with a triangle SNZ. The reflected triangle of y=3 as (1,2),(5,3) and (5,5).

Given that,

In the picture, There is graph with a triangle.

The triangle is SNZ.

We have to find the reflection across y=3.

We have to draw a line on y=3.

On the line y=3,

Z point is there so it will be same that is (5,3).

Now, the point S is on (5,1)

Here, y is 1 that is 3+2=5

So, we take the reflected S point as (5,5)

Now, the point N is on (1,4)

Here, y is 4 that is 3-1=2

So, we take the reflected N point as (1,2).

Therefore, we get the reflected triangle of y=3 as (1,2),(5,3) and (5,5).

The correct answer is 1/3x

Option B is the correct answer

We have that the following two points lie on the line:

• (-2, 0) and (4, 6)

And we need to find the equation of the line that passes through both points.

To find the equation of the line, we can proceed as follows:

1. Apply the two-point equation of the line, which is given by:

2. We have to label both points as follows:

• (-2, 0) ---> x1 = -2, y1 = 0

• (4, 6) ---> x2 = 4, y2 = 6

3. Now, we can substitute the corresponding points into the two-point equation of the line:

Therefore, we have that the slope of the line is m = 1, and the equation of the line is y = x + 2.

Therefore, in summary, the equation of the line is y = x + 2 (Option D).

It should be noted that when multiplying powers you add rather than multiply the exponents in order to give an accurate value as multiplication do powers means the addition of the powers.

Exponentiation is a mathematical process that involves the base b and the exponent or power n. It is represented as bⁿ and is pronounced as "b to the n."

Algebra is the study of mathematical symbols, and logic is the manipulation of those symbols.

For example 3⁴ × 3² will be 3^6 rather than 3^8.

A general solution of a trigonometric function gives all possible solutions of the trigonometric functions and comprises of the integer n.

The given function is presented as follows;

f(x) = 2•sin(x)

The solution of the function is given by the point where f(x) = 0 as follows;

When f(x) = 0

2•sin(x) = 0

Therefore;

Sheila's mapping diagram doesn't represent a function because it includes the points (3, 6) and (3, 6) and fails the vertical line test.

An illustration of two circles that depicts the relationship between input and output values is known as a mapping diagram. By drawing an arrow from one x-value to its corresponding y-value, the x-values (inputs) in the image are transferred to the y-values (outputs).

It does not represent a function because the same input value, 3, is mapped to more than one output value, 3 and 6. Her relation has the following ordered pairs: (1, 1), (2, 2), (3, 3), (3, 6), (4, 4), 5, 5), and (6, 6). Since both (3, 3) and (3, 6) have the same x-coordinate, the relation fails the vertical line test and is not a function.
