The Solution.

The function is increasing on the interval below:

The function is decreasing on the intervals below:

To answer this we have to apply the simple interest formula:

I =P x r x t

Where:

I= interest

P= Principal

R= Interest rate ( in decimal form)

t = time (years)

Replacing with the values given:

Interest= I

Principal = ?

Interest rate = 2/100 =0.02

time= 5 years

I = P x 0.02 x 5

I= 0.1P

Amount= P+I

A = P+0.1P

5,000= P+0.1P

5,000= 1.1P

5,000/1.1 =P

4,545.45 =P

Area of shaded triangle = Area of triangle - area of circle

Area of triangle = 1/2 x base x height

Base= 16 yds

Height= 19 yds

Area of triangle = 1/2 x 16 x 19 = 8 x 19 =152 square yard

Area of shaded triangle = 152 - 78.5 =73.5 square yard

Piecewise Function

We are given the piecewise function shown in the figure.

We are required to calculate g(4) - 3g(3).

First, we calculate g(4). Since 4 is greater than 3, we use the second function:

Now we need to calculate g(3). We use the same function because 3 is greater or equal to 3:

Now we calculate:

g(4) - 3g(3) = 273 - 3*90 = 273 - 270 = 3

Answer: 3

Given that 25% of 80 is 10% of a number.

We have to find the number.

Let the number be x. So, 25% of 80 is equal to 10% of x. Therefore,

Thus, the number is 200.

From properties of linear equation, 1036 students attend east high school.

What is linear equation?

An algebraic equation with simply a constant and a first-order (linear) term, such as y=mx+b, where m is the slope and b is the y-intercept, is known as a linear equation.

Let east high school have x students

West high school have 2x - 250

Total count of students from both the schools are 2858 students.

Then we get

x + 2x-250 = 2858

=> 3x - 250 = 2858

=> 3x = 2858 + 250

=> 3x = 3108

=> x = 3108/3

=> x = 1036

Therefore, 1036 students attend east high school.

We use the formula for the area "A" of a square with equal sides of length "l":

Since we know the value of the area is:

We substitute that value into the formula for the area:

Next, we take the square root of both sides of the equation:

On the right side, the exponent and the square root will cancel, and we will get "l", and on the left side, we calculate the square root:

The question wants us to list out all the possible outcomes in question 18

From the question

We have a spinner that has 5 possible outcomes

The outcomes of flipping a coin are

Thus, to get the possible outcomes, we will have

Step-by-step explanation:

as the intersection angles of parallel lines with a third line are the same for both parallel lines (and then vice versa for the other pair of parallel lines), we have a lot of equal angles here.

not to forget : the sum of all angles around a single point on one side of a line is always 180°.

51 = (y + z)

(6z + 9y) = x

x + (x + z) = x + 51 = 180°

x = 129°

we have now

y + z = 51

9y + 6z = 129

so,

z = 51 - y

9y + 6(51 - y) = 129

9y + 306 - 6y = 129

3y = -177

y = -59

z = 51 - y = 51 - -59 = 51 + 59 = 110

the value of z that makes j and k parallel is 110.

slope of line is -3 for points (1,0) and (0,3)

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

From graph let us take two points (1, 0) and (0, 3)

x₁=1, x₂=0, y₁=0,y₂=3

Substitute these values in slope formula

m=3-0/0-1

m=3/-1

m=-3

Hence slope of line is -3.

not continuous, 2 holes. Option A is correct

For a function to be continuous, the left hand limit of a function must be equal to the right hand limit at the point x = a

From the graph shown you can see that the limit of the function from the left is not equal to the limit of the function from the right at x = 0. Therefore, we can conclude that there are discontinuities at x = 0.

You can also see that the function has 2 holes at (0, 0) and (0, -1).

The next statement is

A rhombus can have different diagonals, and in fact they have. Then let's go to the next one

Pro

∠6 and ∠5 are alternative interior angle thus the measure of angles ∠5 = 45° , ∠6 = 45° ,∠7 = 45° and ∠8 = 135°.

An angle is a geometry in plane geometry that is created by 2 rays or lines that have an identical terminus.

The identical endpoint of the two rays—known as the vertex—is referenced as an angle's sides.

Angles 1,2,7 are the interior angles of a triangle and we know that the sum of all interior angles inside a triangle is 180°.

Therefore, ∠1 + ∠2 + ∠7 = 180°

Given, ∠1  = 70° and  ∠2  = 65°

∠7 = 180° - (70 + 65) = 45°

Now, ∠8 = 180 - ∠7 ⇒ ∠8 = 135°

Now, ∠7 = ∠6 (vertical opposite angle) so ∠6 = 45°

∠6 = ∠5 (alternative interior angle) so ∠5 = 45°

Hence "∠6 and ∠5 are alternative interior angle thus the measure of angles ∠5 = 45° , ∠6 = 45° ,∠7 = 45° and ∠8 = 135°".

Okay, here we have this:

Considering the provided information, we are going to identify approximately how far is the pizza place from the school, so we obtain the following:

Then from the given information we can identify that the pizzeria can be 5 miles in the same direction from the school or 5 miles in any other direction,

This means that in the best case the distance from the pizzeria to the school is 5 miles (if it is halfway), and in the worst case it is 15 miles (if it is in a completely opposite sense).

And in an average case it can be at an angle other than 180 degrees, with which the distance would be between 5 and 15 miles, therefore the correct answer is:

The pizza place is between approximately 5 to 15 miles away from school.

Explanation:

Pay of Dan's car wash attendant job =$400 per week

The amount he earns per hour walking dogs = $15

Let the number of hours spent walking dogs in a week = x

Therefore, total earning for walking dogs =$15x

Since he wants to earn more than $520, we have that:

We can rewrite this as:

If we collect like terms, we have:
