Mac drives 2921 miles per week as compared to Tia

Comparing numbers is a technique for determining if one number is equal to, smaller than, or larger than the other numbers. To compare two numbers, we write them using several symbols. In our daily lives, we make comparisons of figures, such as the daily temperature, the cost of things used on a regular basis, our height and weight, etc. The number with more digits is greater than the number with fewer digits when they are natural numbers.

Miles drove by Tia = 127 miles a week

Miles driven by Mac = Miles driven by Tia*23

= 127*23

2921

So, Mac drove 2921 miles

To find out if the system has a single solution, we have to check wheter its equations are not equivalent to one another and no equation contraticds the others.

If these are some cases, we will find out while we answer, because you will either find an equation that the variable can have any number or we will get to an equation that is wrong for any value of the variable.

To find the solution, we will have to reduce the system to two variable and then to one variable.

To do this, we can pick a variable to get rid of and pair equations so we can achieve this.

Let's get rid of variable y by elimination.

Firstly, we can see that the first equations can by simplifies by dividing it by 3:

Now, since we want to eliminate y, we need to match its coefficient with another equation, but with opposite sign.

The second equation has a coefficient of -2 on y, so if we multiply the first simplified equation by -2, we will get:

Now, we can add this equation with the second:

Now, we will do similarly but with the last equation. The coefficient of y on it is -4, so we multiply the first simplified equation by (-4):

And add the third equation to it:

Notice that we can change the sign of all terms on this equation:

Now, we have two equations and two variable:

However, notice that the left side of the equations are equivalent, because if we multiply the first equation by two, we will get the pair:

So, the left side is equivalent, but the right sides are different, this means that one equation contradicts the other, That is, there is no possible pair of x and z so that these equations are both true.

This means that there is no solution to this system of equations.

A rise or a decline may be represented by an exponential function in either direction.

This is further explained below.

A)

The exponential function is represented as follows for fuel A:

f(x)=2.96(1.04)^x

A representation of an exponential function looks like this:

y=a b^x

Where b is the rate being calculated.

b=1.04

Since b (which is equivalent to 1.04) is bigger than 1, it follows that the price of gasoline A is going up.

B)

A representation of an exponential function may be seen in the table.

To get the cost of gasoline type B, just divide the current price by the price that was in effect just a moment ago.

Therefore, we have:

[tex]\begin{aligned}&b=\frac{3.41}{3.22} \\&b=1.06\end{aligned}[/tex]

1.06 is a higher number than 1.04, by way of comparison (the rate of fuel A).

Consequently, gasoline B had a bigger percentage shift in price than fuel A did.

According to the solution of the fractions. Hiroko cuts her string into 6 equal-size pieces.

A fraction, which derives from the Latin word fractus, which means "broken," is a portion of a whole or, more broadly, any number of equal pieces.​The numerator and denominator of positive common fractions are both natural integers. The denominator shows how many of the numerator's equal parts make up a unit or whole, while the numerator reflects the number of equal parts.

When a fraction is divided, it reciprocated i.e, denominator and numerator change their places. So, in given fraction-

According to the formula of cylindrical volume, we can find out that the rate at which the height of the water level is changing is [tex]\frac{3}{200\pi } inch/min[/tex].

Water is increasing at a rate of ( 3/200π ) inch/min in a cylindrical tank.

It is given to us that, for a right cylindrical tank,

Radius of the base, r = 20 inch ----- (1)

The rate of water poured into the cylindrical tank,

[tex]\frac{dV}{dt}[/tex] = 6 cubic inch per min ------- (2)

We have to find out the rate of change of height when the water level is 12 inches high.

This implies, we need to calculate [tex]\frac{dh}{dt}[/tex].

To find out [tex]\frac{dh}{dt}[/tex] , we have to use the equation for the volume of a right cylinder.

Let us say, the volume of cylinder is represented as V

We know, the formula of volume of a cylinder is

Differentiate equation (4) with respect to time,

[tex]\frac{d}{dt} V = \frac{d}{dt}[ \pi 400 h]\\= > \frac{dV}{dt}= \pi 400\frac{dh}{dt}[/tex] ----- (5)

Step-by-step explanation:

I assume you need the equation in slope-intercept form :

y = ax + b

"a" is the slope, "b" is the y-intercept (the y-value when x = 0).

the slope is defined as ratio (y coordinate change / x coordinate change) when going from one point on the line to another.

let's use the 2 points, where the line intersects the x- and the y- coordinate axis : (0, 9) and (9, 0)

that gives us "b" already : the y-value when x = 0 is 9.

about the slope "a" :

x changes by +9 (from 0 to 9).

y changes by -9 (from 9 to 0).

the slope is then -9/+9 = -1/1 = -1

Step-by-step explanation:

[tex](2x + 5)^{2} - 7 = 0[/tex]

Add 7 to both sides of the equation.

[tex](2x + 5)^{2} - 7 + 7= 0 + 7[/tex]

Subtracting 7 from itself leaves 0.

[tex](2x + 5)x^{2} =7[/tex]

Take the square root of both sides of the equation.

[tex]2x + 5 = \sqrt{7} \\2x + 5 = -\sqrt{7}[/tex]

Subtract 5 from both sides of the equation.

[tex]2x + 5 - 5 = \sqrt{7} - 5 \\2x + 5 - 5 = - \sqrt{7} - 5[/tex]

Subtracting 5 from itself leaves 0.

[tex]2x = \sqrt{7} - 5 \\2x = - \sqrt{7} - 5[/tex]

Subtract 5 from [tex]\sqrt{7}[/tex].

[tex]2x = \sqrt{7} - 5[/tex]

Subtract 5 from [tex]-\sqrt{7}[/tex].

[tex]2x = -\sqrt{7} - 5[/tex]

Divide both sides by 2.

[tex]\frac{2x}{2} =\frac{ \sqrt{7}-5}{2} \\\frac{2x}{2} =\frac{- \sqrt{7}-5}{2}[/tex]

So we get the roots x = 3 and x = -5. This are the point at which the graph changes its sign.

The quadratic term (the one multiplying x²) is 1, which is positive. Because of that, the parabola of the quadratic expression has a minimum vertex:

For the drawing, it can be seen that when x is between -5 and 3, the equation has a negative sign, while when x is lower than -5 or greater than 3 the expression has positive sign. We want the expression:

The Z-score for the 40-week gestation period baby weights 2450 grams is -0.86 is smaller.

The provided deals with Z-scores. A Z-score shows how many standard deviations away from the mean an element is. A numerical evaluation of a value's relationship to the mean within a group of values is called a Z-score. Z-scores can also be favorable or unfavorable.

The score is above the mean, as indicated by the positive value.

The score is below average as indicated by the negative value.

Given the information,

The mean weight and standard deviation of newborns born after a gestation of 32 to 35 weeks are 2700 grams and 800 grams, respectively.

Consequently, the 33-week gestation baby's Z-score is 2250 grams.

Z = σx − μ​ = (2250−2700) / 800 ​= -450 / 800 ​= −0.5625

The goal is to calculate the Z-score for babies born at 33 weeks gestation.

There is sufficient data to infer, based on the Z-score, that the 33-week gestation period falls 0.56 standard deviations below the mean.

According to the data, babies that are born after a gestation of 40 weeks have a mean weight of 2900 grams and an average range of 445 grams.

Consequently, the baby's Z-score at 40 weeks of pregnancy, weighing 2450 grams, is

Z = σx − μ ​= 385 / 2450 − 2900 ​= 385 / -450 ​= -0.86

The goal is to calculate the Z-score for baby weights at 40 weeks of gestation.

There is sufficient data to infer, based on the Z-score, that the 40-week gestation time falls 0.86 standard deviations below the mean.

The infant weighs 2250 grams at 33 weeks gestation, and the Z-score is -0.56.

The baby weighs 2450 grams at 40 weeks of pregnancy, and the Z-score is -0.86.

Since the infant weighs 2450 grams during 40 weeks of gestation, the Z-score for that period is lesser at -0.86.
