Answer:

y-7=-(4/3)(x-5)  (point slope form)

y=-(4/3)x+(41/3) (slope intercept form)

4x+3y-41=0 (general form)

Step-by-step explanation:

step 1

Find the slope of the perpendicular line to 4y-3x+9=0

If two lines are perpendicular, then the product of their slopes is equal to -1

4y-3x+9=0

4y=3x-9

y=(3/4)x-9/4 -----> the slope is m=3/4

The perpendicular slope is

m*(3/4)=-1

m=-4/3

step 2

Find the equation of the line into slope point form

y-y1=m(x-x1)

we have

(x1,y1)=(5,7)

m=-4/3

substitute

y-7=-(4/3)(x-5) ----> equation of the line into point slope form

Convert to slope intercept form ----> y=mx+b

y-7=-(4/3)(x-5)

y-7=-(4/3)x+(20/3)

y=-(4/3)x+(20/3)+7

y=-(4/3)x+(41/3) -----> equation of the line into slope intercept form

Convert to general form ----> Ax+By+C=0

y=-(4/3)x+(41/3)

Multiply by 3 both sides

3y=-4x+41

4x+3y-41=0 -----> equation of the line in general form

addition since inverse means opposite

To isolate p in this equation you have to add 20 to both sides, since addition is the inverse operation of subtraction and vise versa. Adding 20 to both sides will cancel it out of the left side since -20 + 20 = 0.

[tex]f\left(x\right)=x^2-3x-54[/tex]

Step-by-step explanation:

Given function is [tex]f\left(x\right)=x^2-3x-54[/tex].

Now we need to rewrite that equation in standard form.

Given equation is a polynomial function. So to write that in standard form, we need to rearrange terms in descending order of exponents of the variable (x).

We see that exponents of variable x are 2, 1  and 0.

Terms are already written in descending order of exponents.

Hence final answer is given function itself. [tex]f\left(x\right)=x^2-3x-54[/tex]

Answer:  [tex]y=-7[/tex]

Step-by-step explanation:

The equation of the line in Slope-intercept form is:

[tex]y=mx+b[/tex]

Where "m" is the slope of the line and "b" is the y-intercept.

Find the slope with this formula:

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Given the points (-10,-7) (3,-7), substitute values into the formula. Then:

[tex]m=\frac{-7-(-7)}{-10-3}\\\\m=\frac{0}{-13}\\\\m=0[/tex]

Substitute the slope and any point into  [tex]y=mx+b[/tex] and solve for "b":

[tex]-7=0x+b\\b=-7[/tex]

Then, substituting "m" and "b" into the equation  [tex]y=mx+b[/tex], you get that the equation of this line is:

 [tex]y=0x-7[/tex]

 [tex]y=-7[/tex]

|x-99|<3

Step-by-step explanation:

|x-99|<3

The correct mathematical inequality representation for the problem given would be |x - 99| ≤ 3, accounting for people three places ahead or behind the 99th person in line who are eligible to win.

The inequality to find all the winners of the movie tickets, based on the information given, would be |x - 99| ≤ 3. This way of expressing the relationship tells us that as we move three places forward or backwards from the 99th person in line, they are still within the range to win a free movie ticket. The 'x' in the inequality stands for the position in line. In this case, the solution to the inequality |x - 99| ≤ 3 is the set of all numbers in line that are within three places of the 99th person, which are positions 96 to 102 inclusively.

Answer:

The answer is D

Step-by-step explanation:

(12 + 6) x ( 11 - 7) = 72

18 x 4 = 72

72 = 72

Answer:

The answer is D.

Step-by-step explanation:

The only equation that equals 72 is letter D. if you add 12 + 6 you get 18 so now the equation is 18 * (11 - 7) = 72 then you do 11 - 7 and get 4 so now the equation is 18 * 4 = 72 and 18 * 4 equals 72 so your answer is correct.

The probability of drawing the coin labeled '1' from a bag containing coins labeled '1', '2', and '3' is 1/3, or roughly 0.333. This represents a 33.3% chance.

The question is asking you to calculate the probability of drawing the coin labeled '1' in one draw from a bag of three coins, each labeled '1', '2', or '3'. In probability, we define an event's likelihood as the number of ways that event can occur divided by the total number of possible outcomes.

Here, the event we're interested in is picking the coin labeled '1'. Since there is only one coin labeled '1', there is just one way this event can occur. The total number of possible outcomes is defined by the number of coins in the bag, which is 3 – the coins labeled '1', '2', and '3'.

Therefore, the probability of drawing the coin labeled '1' is calculated as 1/3, or roughly 0.333 when rounded to three decimal places. That means there is approximately a 33.3% chance that the coin labeled '1' will be the next drawn from the bag.

Explanation:

We are given that the original number of charms that Rosie has is c

We know that Ray gave Rosie 3 new charms

This means that the number of charms that Rosie originally had increased by 3

To express this increase, we use addition where we add 3 to the original number of charms that she had

New number of charms = original number of charms + 3

New number of charms = c + 3

The sum of the  infinite geometric series is:

                                 -288

We know that the sum of the infinite geometric series:

            [tex]a=-144[/tex]

and the common ratio of the series is:

[tex]r=\dfrac{1}{2}[/tex]

Hence, the sum of the series is:

4. Radius is 3.1

Hope this helps!

Step-by-step explanation:

The area of the base of first cylinder is 47.05 in², volume of a cone is 3421.2 in³, the  volume of a sphere is 11494.04 cm³ and the radius of last sphere is 3.102 cm.

Volume of cylinder is the amount of quantity, which is obtained by it in the 3 dimensional space.

Volume of cylinder can be given as,

V=πr²h

Here, (r) is the radius of the base of the cylinder and (h) is the height of the cylinder.

The area of the base of a cylinder with a volume of 240π in³ and a height of 16 inches has to be find out. The radius of this cylinder is,

V=πr²h

240π=πr²(16)

r=√(240/16)

r=3.87 in

Thus, the surface area of the base is

A=πr²

A=π(3.87)²

A=47.05 in²

The volume of a cone with a height of 27 inches and a radius of 11 inches is,

V=(πr²h)/3

V=(π(11)²(27))/3

V=3421.2 in³

The volume of a sphere with a radius of 14 cm is;

V=(4πr³)/3

V=(4π(14)³)/3

V=11494.04 cm³

The volume of a sphere is 125 π cm³. The radius of it is,

V=(4πr³)/3

125=(4πr³)/3

r=∛(93.75/π)

r=3.102 cm.

Thus, the area of the base of first cylinder is 47.05 in², volume of a cone is 3421.2 in³, the  volume of a sphere is 11494.04 cm³ and the radius of last sphere is 3.102 cm.

3 times a number is 4 less than the square of that number. The negative solution is  -1

What are quadratic equations?

Quadratic equations are of the form ax² + bx + c where a ≠ 0.

Factorization, often known as factoring, is the process of expressing a number or another mathematical object or mathematical equations as a product of several factors.

Now, In the given question let's first assume that the unknown number is a variable x.

So, 3 times that number is (3 × x)

And then, 4 less than the square of that number is (x² - 4)

Now, as the question states that 3 times a number is 4 less than the square of that number,

So we can write,

3x = x² - 4

Now, we have to solve this quadratic equation with the help of factorization.

To solve the quadratic equation we first bring all the terms to any of the sides and after rearranging a little the equation is as follows:

x² - 3x - 4 = 0

Now, if we want to find the factors in the form ax² + bx + c we need to multiply a and c and then we have to identify what two numbers sum up to b and multiply to ac.

Here, a = 1, b = -3 and c = -4

Now, ac = -4

So, we have to identify what two numbers sum up to b and multiply to ac. The numbers are -4 and 1 and we can check that they sum up to -3 and multiply to -4.

So first we have to split the equation: x² - 3x - 4 = 0

x² - 4x + 1x - 4 = 0

Now, we have to group the above equation,

(x² - 4x) + (1x - 4) = 0

Taking x common from the first group and taking 1 common from the second group we get,

(x)(x - 4) + (1)(x - 4) = 0

Now, again taking (x - 4) common from the equation we get,

(x - 4) × (x + 1) = 0

So, we set each factor to zero now,

(x - 4) = 0

Adding 4 to each side of the equation we get,

x - 4 + 4 = 4

Simplifying we get,

x = 4

(x + 1) = 0

Adding -1 to each side of the equation we get,

x + 1 - 1 = -1

Simplifying we get,

x = -1

So, we now have two solutions of x that is 4 and -1

But according to the question we only need the negative one.

Therefore, the negative solution is  -1

Answer:

log(M/N) = 4, log(P/N) = 5

log M - log N = 4

log P - log N = 5

log P - log M = log(P/M) = 1

P/M = 10

P = 10M

The correct answer is C.

Since it is evident that P is in fact ten times larger than M, the right response is P = 10M Option C is correct.

To solve this problem

Given that log(M/N) = 4, log(P/N) = 5 and both logarithms have the same base, let's consider the relationship between M and P

Since Log (M) = 4 this implies that M =[tex]10^4[/tex]

Similarly, Log ( P) = 5 this implies that P = [tex]10^ 5[/tex]

Now, we can compare P and M :

[tex]P = 10^5[/tex]

[tex]M = 10^4[/tex]

Since it is evident that P is in fact ten times larger than M, the right response is:

C . P = 10M

Therefore, This reflects the relationship that P is 10 times M.

Option A,-10.4% is the rate of change of stock XYZ for this particular week.

How to find percentage change?

Step 1: Calculate the change (subtract old value from the new value)

Step 2: Divide that change by the old value (you will get a decimal number)

Step 3: Convert that to a percentage (by multiplying by 100 and adding a "%" sign)

Note: when the new value is greater then the old value, it is a percentage increase, otherwise it is a decrease.

Finding percentage change

We have given,On Monday, stock XYZ opened at $4.53 which is the initial value or old value

On Friday, it closed at $4.06,which will be final value or new value.
