Step-by-step explanation:

i dont know

The information that is needed to write the equation of a line in point-slope form is the location of one ordered pair that lies on the line and the line's slope. The correct option is the first option

From the question, we are to determine the information that is needed to write the equation of a line in point-slope form.

The point-slope form of a line is given as

y - y₁ = m(x - x₁)

Where, (x₁, y₁) is a point on the line

and m is the slope of the line

Thus, in order to write the equation of a line in the point-slope form, the information that are needed are:

1. An ordered pair on the line

2. The slope of the line

One possible solution is X = 0, Y = 8, and Z = 4.

To find the values of X, Y, and Z in the addition problem, let's analyze the sum:

  XYZ

+ XYZ

+ XYZ

_____

 YYY

We know that when we add two three-digit numbers, the sum in the ones place (Z) can only be a single-digit number.

Therefore, the sum of Z + Z + Z should equal Y.

Since the sum in the ones place results in a three-digit number (YYY), it means that Z + Z + Z = Y must result in a number greater than or equal to 100.

Let's try some possible values:

If Z = 1, then 1 + 1 + 1 = 3. But this doesn't fulfill the condition that Y must be greater than or equal to 100.

If Z = 2, then 2 + 2 + 2 = 6. This still doesn't fulfill the condition.

If Z = 3, then 3 + 3 + 3 = 9. Again, this doesn't fulfill the condition.

If Z = 4, then 4 + 4 + 4 = 12. Finally, this meets the condition since Y can be 12.

Therefore, we have:

  444

+ 444

+ 444

_____

 888

In this case, X can be any digit since it doesn't affect the final sum. So, X can be any number from 0 to 9.

Thus, one possible solution is X = 0, Y = 8, and Z = 4.

Step-by-step explanation:

The volume of the cylinder will increase by a factor of 4 if the radius of the cylinder doubles.

Volume is the amount of space occupied by a three-dimensional object or region of space and expressed in cubic units.

To get the volume of a cylinder, multiply the area of the circular base with the height:

V = \(\pi r^{2} h\)

where

r is the radius of the base (circle) of the cylinder

h is the height of the cylinder

Thus, the volume of cylinder directly varies with its height and directly varies with the square of its radius

So if the radius of the cylinder doubles,

V = \(\pi (2r)^{2}h\)

V = \(\pi (4r^{2}) h\)

V = \(4\pi r^{2} h\)

Then, the volume will increase by a factor of 4.

A Z-test for proportions, you will be able to determine if there is a significant difference in the preference of middle school children for the bookbag company's product compared to the reported 55%.

For the scenario described, we need to identify the parameter of interest, choice of test, and hypotheses.

a. Parameter of interest: In this case, the parameter of interest is the proportion of middle school children who prefer the bookbag company's product over their closest competitor's.

b. Choice of Test: Since we are dealing with proportions, the appropriate test to use is a hypothesis test for proportions, specifically the Z-test for proportions.

c. Hypotheses:

Null Hypothesis (H0): p = 0.55, meaning there is no difference and 55% of middle school children prefer the bookbag company's product.

Alternative Hypothesis (H1): p ≠ 0.55, meaning there is a significant difference, and the proportion of middle school children who prefer the bookbag company's product is not 55%.

Answer:

1. ac = 36

2. b = 13

3. 4 and 9

Step-by-step explanation:

Given

6x² + 13x + 6

Required

Fill in the gaps

Solving (1): The value of AC

The general form of an equation is:

ax² + bx + c

By comparison:

a = 6

b = 13

c = 6

So,

ac = a * c

ac = 6 * 6

ac = 36

Solving (2): The value of b

In (1) above, we showed that

b = 13

Solving (3): Two numbers that satisfy product ac and sum b

We have that.

ac = 36

If one of the numbers is 4, then the other number is

Other number = 36/4

Other number = 9

Alternatively, we have that.

b = 13

If one of the numbers is 4, then the other number would be:

Other number = 13 - 4

Other number = 9

Answer:

ac = 36

b = 13

The two numbers that have a product of ac and a sum of b are 4 and 9

Answer:

n + m = 8.27; 3n + 5m = 20.22

Step-by-step explanation:

Let

Cost of the novel = n

Cost of the magazine = m

The cost for a novel and a magazine is $8.27.

n + m = 8.27 (1)

The cost for 3 novels and 5 magazines is $20.22

3n + 5m = 20.22 (2)

The pairs of equation to determine n, cost of the novel and m, cost of the magazine is

n + m = 8.27; 3n + 5m = 20.22

Combining (1) and (2)

The logical expression that represents the statement "Despite the fact that it is sunny today, I will bring my umbrella" is (B) s∧m.

The logical expression that represents the statement "Despite the fact that it is sunny today, I will bring my umbrella" is (B) s∧m. This is because the conjunction "and" (∧) is used to connect two statements that must both be true in order for the overall statement to be true.

Answer:

Jeff is faster

Step-by-step explanation:

kilometers are faster than meters

and 7 kilometers is 700 meters

so 100 meters isn't fast enough compared to Jeff's speed

Jeff is faster than Cameron as his average speed is more than that of Cameron's average speed.

The average speed of a body is the ratio of the distance covered by the body to the time it takes to cover that distance.

In the question, we are given that Jeff says that he can run 7 kilometers per hour while Cameron says that he can run 100 meters per minute.

We are asked to tell who is the faster among them.

We need to know that, 1 kilometer = 1000 meters, and 1 hour = 60 minutes.

Jeff's average speed = 7 km/hr. = 7km/1hr = (7*1000) m / (1*60) min

or, Jeff's average speed = 7000/60 meters per minute = 116.67 meters per minute.

We are given that Cameron's average speed is 100 meters per minute.

So, we can say that Jeff is faster than Cameron, as

Jeff's average speed > Cameron's average speed.

∴ Jeff is faster than Cameron as his average speed is more than that of Cameron's average speed.

the rate of change of the radius at the instant the volume equals 36π cm³ is 7 / (36π) cm/sec.

The volume V of a sphere with radius r is given by the formula V = (4/3)πr³. We are given that the rate of change of the volume is 7 cm³/sec. Differentiating the volume formula with respect to time, we get dV/dt =(4/3)π(3r²)(dr/dt), where dr/dt represents the rate of change of the radius with respect to time.

We are looking for the rate of change of the radius, dr/dt, when the volume equals 36π cm³. Substituting the values into the equation, we have: 7 = (4/3)π(3r²)(dr/dt)

7 = 4πr²(dr/dt) To find dr/dt, we rearrange the equation: (dr/dt) = 7 / (4πr²) Now, we can substitute the volume V = 36π cm³ and solve for the radius r: 36π = (4/3)πr³

36 = (4/3)r³

27 = r³

r = 3  Substituting r = 3 into the equation for dr/dt, we get: (dr/dt) = 7 / (4π(3)²)

(dr/dt) = 7 / (4π(9))

The problem represents a geometric progression.

The general form of a geometric sequence is:

where a = first term

r = common ratio

The first term from the table is the first price (for the first month). That is $80.00

To find the common ratio, we divide a term by its preceeding term.

Let us divide the price of the second month from the first.

We have:

The price after the 8th month is the value of a(n) when n = 8

So, we have that:

The estimation of 0.000007328 is \(7\times10^{-6\).

Estimation is he ability to guess the amount of anything without actual measurement.

The number (n) is given as:

\(\text{n}=0.000007328\)

Multiply by 1

\(\text{n}=0.000007328\times1\)

The number is to be rounded to the nearest millionth.

So, we substitute \(\frac{1000000}{1000000}\) for 1

\(\text{n}=0.000007328\times1\)

\(\text{n}=0.000007328\times\dfrac{1000000}{1000000}\)

This becomes

\(\text{n}=7.328\times\dfrac{1}{1000000}\)

Express the fraction as a power of 10

\(\text{n}=7.328\times10^{-6\)

Approximate to a single digit
