ANSWER

The graph of function g is the graph of function f stretched horizontally by a factor of 4.

EXPLANATION

Function g(x) is a transformation of function f(x), obtained by multiplying the variable, x, by 1/4. This is described as a horizontal stretch by a factor of 4.

Hence, the graph of function g is the graph of function f stretched horizontally by a factor of 4.

To prove that the sum of the remote interior angles and the exterior angle have the same value, we recall 2 things:

1.- the inner angles of a triangle add up 180 degrees

2.- angle 3 and angle 4 are supplementary which means that they add up 180 degrees.

Answer:

They are linear pair and therefore supplementary.

We are asked to determine wheater 6/10 in decimal form is repeating or terminating. To do that we need to divide 6 over 10. To do that, we proceed as follows:

We need to find a number that when multiplied by 10 gives 6. That number is 0.6, because:

Therefore 6/10=0.6 Since the numbers after the radix point do not repeat, this is a terminating decimal.

The formula to obtain the angle of rotation is as follows:

Compare the given equation to the general equation of a conic.

Substitute the values into the equation.

Find the value of the θ.

If the unknown number is an integer between 280 and 349;

When rounded to the nearest hundred, the unknown number is 300.

If the unknown number is an integer from 350-380;

When rounded to the nearest hundred, the unknown number is 400.

If the approximation is 45 less than the original number, thus it cant be in the range of 350-380.

But;

When 345 is rounded to the nearest hundred, it is 300.

And the difference between the approximated value and the original value is 45.

Hence, 345 is the original number.

CORRECT ANSWER: 345

A three-course meal will contain 1 pizza, 1 salad, and 1 dessert.

The question tells us that there are 4 different salads, 5 different pizzas, and 3 different desserts.

Therefore, the total number of possible ways a three-course meal can be served is calculated as the product of all the numbers. This is shown below:

60 different meals can be ordered.

Given the equations:

Let's find the point where both equations intersect.

To find the point let's first find the value of x by equation both expression:

Now, equate to zero:

Now let's factor by grouping

Solve each factor for x:

We can see from the given options, we have a point where the x-coordinate is 1 and the y-coordinate is 8.

Since we have a solution of x = 1.

Let's plug in 1 in both function and check if the result with be 8.

We can see the results are the same.

Therefore, the point where the two equations meet is:

(1, 8)

ANSWER:

B. (1, 8)

Given

x = 5

5x + 2 = 27

Procedure

d. Yes, because when x is replaced by 5 the equation is true. ​

Equation: S = $70·W + $550

Amount of manoey after 18 weeks: $1810

To solve this, we have two variables, the amount of weeks (W) and savings (S)

Each week, $70 dolars are added to the account. Then we can write this as: $70·W.

Now there is an initial amount of $550. Then we must add that mount to the previous calculation: $70·W + $550

This give us the savings on each week. THen THe complete equation is S = $70·W + $550

Now, to know the savings after 18 weeks, we can replace W = 18 and solve:

Thus, the savings after 18 weeks is $1810

The value of each line segment is found as 26 units.

For the given question.

The line is given as DE and the mid point of line is D.

Thus,

CD = DE   .....eq 1

The value of each term are given as;

CD = 2x + 7

DE = 4(x - 3)

Put the value in equation 1.

2x + 7 = 4(x - 3)

2x + 7 = 4x - 12

Bring variables and constants on the different sides.

4x - 2x = 7 + 12

2x = 19

x = 9.5

Put the value in each side;

Thus, the value of each line segment is found as 26 units.

If I invest $2000 at 6% interest compounded monthly, it will take 11.58 years by the account to double in value.

What is compound interest?

The practice of adding interest to the principal amount of a loan or deposit is known as compound interest, sometimes known as interest on principal and interest. It happens when interest is reinvested, added to the lent capital rather than paid out, or required to be paid by the borrower, resulting in interest being created the next period on the principal amount plus any accrued interest. Compound interest is a prominent concept in finance and economics.

The initial investment of $2000 at 6% compounded monthly.

Since, the interest rate of 6% is compounding monthly, then the effective annual interest rate will be

= (1+)−1i = (1+rm)m−1

Here, r = interest rate in decimals

= (1+0.0612)12−1i = (1+0.0612)12−1

= 0.061678i = 0.061678

= ×100 = 6.1678%

Now, we are using Rule 72 to calculate the doubling time

Time to double the initial amount = 72 /effective annual interest rate

Time to double the initial amount = 11.58 years

The correlation coefficient between flow rate and amount of eroded soil is:

0.967.

The correlation coefficient is an index that measures correlation between two variables, assuming values between -1 and 1.

If it is positive, the relation is positive, meaning that the variables are direct proportional. If it is negative, the variables are inverse proportional.

If the absolute value of the correlation coefficient is greater than 0.6, the relationship between the variables is strong.

Given a data-set of two points, the correlation coefficient is found inserting points of the data-set into the calculator. In this problem, the points in the data-set are given as follows:

(0.31, 0.82), (0.85, 1.95), (1.26, 2.18), (2.47, 3.01), (3.75, 6.07).
