We will get 7 34/24 after borrowing 1 from the whole number part to rewrite 8 10/24.

What is whole number ?

All of the fundamental counting numbers as well as the number zero are grouped together as whole numbers. Natural numbers are the term used in mathematics to describe counting numbers. Consequently, we can define the whole number as a combination of all natural numbers and 0. Along with zero, all positive integers are considered whole numbers.

Given : 8 10/24

We have to borrow 1 from the whole number, So, we also need to add 1 to the fraction part.

Hence, 8 10/24 - 1 = 7 (1+ 10/24)

                              = 7 ( 24+10 / 24 )

                              = 7 34/24.

You can start this in may ways but let's start by isolating one of the parenthesis:

x (x² - 5) = - (x - 3)

x³ - 5x = -x + 3 (here I multiplied x for what's inside the parenthesis and the "minus" signal by the other parenthesis which was (x - 3))

-0.5(3x+5)= -1.5x+2.5

Step-by-step explanation:

-0.5(3x+5)

multiply-0.5 with 3x and 5 to get rid of the brackets.

-0.5×3x= -1.5x

-0.5×5= 2.5

-1.5x+2.5

Answer:

Using the distributive property to expand the first expression, you would get -1.5x - 2.5. Since the constant term does not have the same sign as the second expression, the two expressions are not equivalent.

Hope this help!

The cartesian equation of the curve defined by x = sin(t) and y = csc(t), 0 < t < π/2,  is y = √(1 - x²).

To eliminate the parameter t, we can use the trigonometric identity

csc(t) = 1/sin(t).

Substituting this into the equation y = csc(t), we have y = 1/sin(t).

Rearranging the equation, we get sin(t) = 1/y. Now, we can substitute the expression for x from the equation x = sin(t) into this equation. This gives sin(t) = 1/y = x.

Taking the square of both sides, we have

sin²(t) = (1/y)²

= x².

Using the Pythagorean identity sin²(t) + cos²(t) = 1,

we can rewrite the equation as cos²(t) = 1 - x².

Since cos²(t) = 1 - sin²(t), we can substitute this into the equation to get

1 - sin²(t) = 1 - x².

Simplifying, we have sin²(t) = x².

Taking the square root of both sides, we get sin(t) = ±x.

Finally, substituting sin(t) with its expression x in the equation y = csc(t), we have y = 1/sin(t) = 1/(±x).

Simplifying further, we have y = ±(1/x).

Hence, the cartesian equation of the curve is y = ±(1/x), or equivalently,

y = √(1 - x²) for the positive root.

Answer:

x = 11

Step-by-step explanation:

We are given a circle.

We know that arc DC is equal to 95°, and that arc CE is 10x+3.

We also know that m<DCE = 76°.

We want to find the value of x.

Recall that an entire circle is 360 degrees in measure.
Also recall that an angle that is inside a circle (an inscribed angle) is half the value of the arc it intercepts.

We can see that <DCE is an inscribed angle; the arc it intercepts is arc DE.

Based on what we know from above, arc DE is twice the value of <DCE.

This means, arc DE = 2(76°) = 152°

As stated above, a circle's full measure is 360 (degrees).

This means that the sum of all the arcs equals 360.

So, arc CD + arc DE + arc CE = 360

Substitute the values we know to get:

95 + 152 + arc CE = 360

247 + arc CE = 360

arc CE = 113

Recall that the value of arc CE is 10x + 3.

So:

10x + 3 = 113

Subtract 3 from both sides.

10x = 110

Divide by 10.

x = 11

A decrease of 2 dB can be accomplished by one or the other by closing down a portion of the machines (since the sound intensity level declines by 6 dB for each splitting of the sound power) or by introducing sound-sealing materials.

The time taken for the population of the pig to reach 1000 will be almost four years.

A function is a statement, rule, or law that establishes the connection between two variables. In mathematics, functions are everywhere and are necessary for constructing physical connections.

Six guinea pigs are released in an area with no natural predators.

The guinea pig population quadruples every year.

Write a function P that represents the guinea pig population at a given time T measured in years.

Then the function will be

\(\rm P = 6 (4)^T\)

Then the inverse function of P will be

\(\rm T = 6 (4)^P\\\\\\P \ln 4 = \ln \left (\dfrac{T}{6} \right )\\\\\\P = \dfrac{\ln (T/6)}{\ln 4}\)

Then the time taken for the population of the pig to reach 1000 will be

\(\rm 1000 = 6 (4)^T\\\\\\166.667 = 4^T\\\\\\T = 3.69 \\\\\\T \approx 4 \ years\)

See below, please!

Step-by-step explanation:

We know that 6z-31+something is going to be equal to 180 degrees, because it is supplementary. But what is that something? We see 67 degrees. Do you think this is a corresponding angle to the something that we need to find? Yes, it is! So we know that 6z-31+67 is equal to 180. So, z is 24. Now, since we know the value of the something (67 degrees because of corresponding angles) we can find yet another pair of supplementary angles. 67+x=180! Kind of neat, huh? So, x is equal to 113.

Hope this helped!

Answer:

The equation of a line is y = ax + b, where a is the slope and b is the y-intercept.  

Since we have the y-intercept, all we need to do is find the slope. To find the slope, you need 2 coordinates.

The y-intercept is where the line crosses the y axis, so it is where x is 0. Since the y intercept is -2, that means the first coordinate is (0, -2)

The x-intercept is where the line crosses the x axis, so it is where y is 0. Since the x intercept is 4, that means the second coordinate is (4, 0)

Since we already have the y-intercept, all we do is put the slope in the equation: y = 1/2x - 2.

Step-by-step explanation:

Line SY bisects angle PSR. To prove that line SY bisects angle PSR, we can use the property that an angle inscribed in a circle is half the measure of the intercepted arc. Here's the proof:

Since XY is a diameter, it subtends a 180-degree angle at any point on the circle. Therefore, angle QXY measures 180 degrees.

Angle PQY is an inscribed angle, and its measure is half the intercepted arc PQ. Similarly, angle YSR measures half the intercepted arc SR.

Since angle QXY is 180 degrees and angle PQY and angle YSR are half of their respective intercepted arcs, the sum of angles PQY and YSR must be 180 degrees.

Therefore, angle PQY and angle YSR are equal, and since angle PQY is congruent to angle PQS (as QX bisects angle PQR), it follows that angle YSR is congruent to angle PSR.

Hence, we have proved that line SY bisects angle PSR.

We want to find two points that belong to the line

The easiest points to calculate are the intercepts. The x-intercept happens when y = 0, to find the corresponding x-value we just need to evaluate y = 0 on the expression for our line.

The x-intercept is (-0.25, 0).

Analogously, for the y-intercept(that happens at x = 0), we have

The y-intercept is (0, -1).

Two points that belongs to this line are (-0.25, 0) and (0, -1).
