Explanation:

Using the graph of both equations, we want to get the correct option

We start by making a plot of the two on same axes

We have the plot of the functions as follows:

Now, let us take a look at the options:

a) This is wrong. The functions have two intersection points

b) This is incorrect. They have equal y-intercepts at y = 2

c) This is correct. The quadratic function have a greater maximum

LK = 2.91m

JK = 7.99m

hypotenuse = 8.5m

angle = 20°

LK = side opposite the angle 20°

Since we know the hypotenuse and we need to find the opposite, we would apply sine ratio

sine ratio = opposite/hypotenuse

sin 20° = LK/8.5

LK = 8.5(sin 20°)

LK = 8.5(0.3420)

LK = 2.907

To the nearest hundredth, LK = 2.91m

JK = base = adjacent

We would apply cosine ratio

cos 20° = adjacent/hypotenuse

cos 20° = JK/8.5

JK = 8.5(cos20°)

JK = 8.5(0.9397)

JK = 7.98745

To the nearest hundredth, JK = 7.99m

In order to determine the amount of money Rain, Kevin and Eric have, write the given situation as an algebraic equation.

If x is the money of Raina, y the money of Kevin and z the money of Eric, you have, based on the given problem, the following equations:

x + y + z = 66 All of them have a total of $66

y = 3z Kevin has 3 times what Eric has

x = z - 9 Raina has $9 less than Eric

Replace the expressions for x and y into the first equation and solve for z, as follow:

(z - 9) + (3z) + z = 66

z - 9 + 3z + z = 66

3z = 66 + 9

3z = 75

z = 75/3

z = 25

Next, replace the previous value of z into the expressions for x and y:

y = 3(25)

y = 75

x = 25 - 9

x = 16

Hence, the amount of money each of them has is:

Raina: $16

Kevin: $75

Eric: $75

EXPLANATION

Given the system of equations:

(1) 60x + 110y = 265

(2) 120x + 90y = 270

We can apply the substraction method as shown as follows:

Multiply 60x + 110y = 265 by 2:

----> (60x + 110y = 265)*2 -------> 120x + 220y = 530

Subtract the equations:

120x + 220y = 530

- (120x + 90y = 270)

--------------------------------

130y = 260

Divide both sides by 130:

y= 260/130

Simplifying:

y= 2

Replacing on the first equation:

60x + 110(2) = 265

Applying the distributive property:

60x + 220 = 265

Subtracting 220 to both sides:

60x = 265 - 220

Subtracting like terms:

60x = 45

Dividing both sides by 60:

x = 45/60

Simplifying:

x= 3/4

The solutions to the system of equations are:

x=3/4 y=2

We have the following inequality:

x > - 0.75

This is the same as state "x is greater than -0.75". Therefore, any value greater than -0.75 is a solution to this inequality

Considering this rule, we can answer each item:

a) The statement "-0.75 is a solution to the inequality" is FALSE, because, or rule states that x must be greater than -0.75.

b) The statement "There are many solutions to this inequality" is TRUE. Actually, there is an infinite number of solutions to this inequality (some of them can be expressed by -0.74, -0.73, -0.72...)

c) The statement "All the solutions to the inequality are negative" is FALSE, since any positive (or null) number is also greater than -0.75.

d) The statement "The inequality -0.75 < x is equivalent to the given inequality" is TRUE, since this inequality is tha same as the statement "-0.75 is less than x", which is a different form of express the original statement "x is greater than -0.75".

e) The statement "-4.5 is a solution to the inequality" is FALSE, because -4.5 is less than -0.75, which contradicts or rule.

Given: 0.6 divided by 30

We will find the result as follows:

So, the answer will be 0.02

1. replace f(x) with y:

2. Replace every x with a y and replace every y with an x:

3. Solve for y:

4. replace y with f-1(x):

Solution:

From the table, the probability that Michiko will hava a quiz on Wednesday is 0.070.

This is the probability of success.

Hence, the probability that Michiko will not have a quiz on Wednesday is the probability of failure.

Thus,

Hence, the probability of failure (the probability that Michiko will not have a quiz on Wednesday is 0.93.

As a percent,

Therefore, the probability that Michiko will not have a quiz on Wednesday is 93%

Answer:

Subtract 4

Explanation:

In the number pattern:

We subtract the next term from the previous term below:

We see that each one gives a subtraction of 4.

Therefore, the rule of the pattern is 'Subtract 4'.

Using midpoint of a line, the point at which E is located on the coordinates is (-4, -10)

Midpoint refers to a point that is in the middle of the line joining two points. The two reference points are the endpoints of a line, and the midpoint is lying in between the two points. The midpoint divides the line joining these two points into two equal halves. Further, if a line is drawn to bisect the line joining these two points, the line passes through the midpoint.

The formula of midpoint is given as

(x, y) = (x₂ + x₁) / 2 , (y₂ + y₁) / 2

Taking x-coordinate

x = (x₂ + x₁) / 2

2 = (8 + x₁) / 2

x₁ = -4

Taking the y - coordinate

y =  (y₂ + y₁) / 2

-4 = (2 + y₁) /2

y₁ = -10

The coordinate of E is (-4, -10)

6The mean number of children each team member will bring

Here, we want to get the mean number of students that each team member willl bring

From the histogram, we can deduce the following;

a) 4 team members will bring no (0) children

b) 3 team members will bring 1 children each

c) 5 team members will bring 2 children each

d) 2 team members will bring 3 children each

e) 1 team member will bring 5 children

So the totla number of children at the party will be;

4(0) + 3(1) + 5(2) + 2(3) + 1(5)

= 0 + 3 + 10 + 6 + 5 = 24 children

The number of team members is 4 + 3 + 5+2 + 1 = 15

So, the mean number each will bring is; the number of children attending the party divided by the number of team members

Question:

What statements are true regarding undefine terms in geometry

A point has no length or width.

This is true because a point cannot have a dimension

A plane consists of an infinite set of lines.

This is not true because from the definition of a plane, it must have an infinite set of lines or points.

A plane has one dimension, length

This statement is not true because a line is a one dimensional object and as such can only have one dimension which is its' length.

A point indicates a location in a coordinate plane.

This statement is true because any point located on a plane must have an ordered pair of an x and y coordinate

A line has a define begging and end

This is not true because A distance along a line must have no beginning or end.

A line consists of an infinite set of points

This is not true becaue a plane consists of an infinite set of points

Hence,

The final answers are

A point indicates a location in a coordinate plane.

A point has no length or width.

Using the function  f(x) = 28.7 + 1.2log (x + 1) that models the salinity of the ocean to depths of 1000 meters the salinity to the nearest hundredth is 32.18 g/kg

The salinity s calculated using the logarithmic function model

f(x) = 28.7 + 1.2log (x + 1)

given that f(x) is in grams of salt per kilogram of seawater and x is the depth in meters

for x = 797 meters

f(x) = 28.7 + 1.2log (x + 1)

f(x) = 28.7 + 1.2log (797 + 1)

f(x) = 28.7 + 1.2log (798)

f(x) = 28.7 + 1.2 * 2.902

f(x) = 28.7 + 3.4824

f(x) = 32.1824

f(x) = 32.18  (to the nearest hundredth)

Before we calculate the perpendicular line, let's rewrite our line equation in slope-intercept form. The slope-intercept form is

Where m represents the slope and b the y-intercept.

Rewritting our equation, we have

This means the slope of our line is equal to - 3.

Two perpendicular lines are related by their slope. Let's say two lines are perpendicular, this means the slope of one of the lines is equal to minus the inverse the slope of the other. If we call the slope of one of those lines as m_1, the slope of the perpendicular line m_2 is given by

Using this relation, we can find the slope of a perpendicular line. Since the slope of our line is equal to - 3, then, the slope of the perpendicular line is

In slope-intercept form, our perpendicular line has the following form

To find our y-intercept, we can use our given point that belongs to this line.

The point is (-3, 1), evaluating this point in our equation, we have

Given:

f(x) = x^2 + 4x + 4 and g(x) = x^2 - 2x - 8.

we are to find the domain of (f/g) (x)

before we find the domain of the function, its best we know what a domain is.

The Domain of a function is the set of all possible inputs for the function. it can also be seen as the set of input or arguement values for which the function is real and defined.

recall that we have x + 2 as our the simplest form

x - 4

so the domain we wil be looking for is x + 2

x - 4

so we have to take t denominator of the above and compare to zero

x - 4 = 0

x = 4

so this is undefined

the function domain

x < 4 or x > 4

so the domain is:

(- infinity, 4) U (4, infinity)

The correct option is A.
