The vertex form of a parabola is given by:

Where the vertex is:

for (1,-2):

therefore:

The monthly payment formula is :

where M is the monthly payment

P is the Financed amount

r is the rate of interest monthly, annual rate divided by 12

n is the number of payments

From the problem,

The financed amount is the difference between the car's cost and the down payment.

P = $19,500 - $2,500

P = $17000

The monthly interest rate is :

r = 3.9%/12 or 0.039/12 = 0.00325

n = 36 months

The monthly payment will be :

a. M = $501.15

b. The total payment for the car is monthly payment multiplied by the number of payment made together with the downpayment.

501.15 x 36 + 2500 = $20,541.4

c. The interest is the difference between the total payment made and the financed amount.

I = 501.15 x 36 - 17,000 = $1,041.4

Given:

4149000000 is the approximation age of oldest rock. The precise amount is not known with certainty. Similar to proximity or approximately, the word "approximation" is derived from the Latin Proximus, which meaning "nearest."

The precise amount is not known with certainty. Similar to proximity or approximately, the word "approximation" is derived from the Latin Proximus, which meaning "nearest." The closest estimate you can make without knowing something's exact size or measurement is called an approximation.

Despite the fact that approximation is most usually used in relation to numbers, it is also regularly used in relation to mathematical functions, forms, and physical laws. In science, the term "approximation" can refer to using a less complex method or model when the proper one is challenging to use.

For this, sampling techniques like Markov chain Monte Carlo and significance sampling as well as variationally methods like mean-field approximations and assumed density filtering have been used.

For the triangle with sides 5, 6 and 9, you have:

5 + 6 > 9

5 + 9 > 6

9 + 6 > 9

9² ≠ 5² + 6²

≠ 25 + 36

≠ 61

Then, it is not a right triangle

For the triangle with sides 4, 8 and 12:

4 + 8 ≥ 12

in this case the triangle inequality is not present

12² ≠ 4² + 8²

Then, it is not a right triangle

For the triangle with sides 7, 8 and 17:

7 + 8 < 17

in this case the triangle inequality is not present

17² ≠ 8² + 7²

Then, it is not a right triangle

ANSWER

D. Zero

EXPLANATION

The triangle inequality states that the sum of any two sides of a triangle is greater than the third side,

All these inequalities must be true to be able to form a triangle with the given sides,

Hence, no triangle can be formed with these side lengths.

A area= 72

Q area =5

So, if we multiply the A area by the square of the scale factor ( since they are areas) we obtain area Q:

72 x^2 = 5

Solving for x:

x^2 = 5/72

x = √(5/72)

x= 0.26

μ =  782.02 is the mean of the distribution of scores by standard deviation.

What is standard deviation in math?

we have from standard normal table that

P(Z > 1.282) = 0.1

Therefore the given Z score of a score of 700 is given thus 1.282.

the z score is given:

x - μ / α = 1.282

700 - μ / 90 = 1.282

Therefore μ = (700 - 90)*1.282 = 782.02

So we have that μ =  782.02

He needs option D. Because the perimeter is not the total area (it is only the distance in meters/centimeters that surround the lawn, we need to know how much area a bag of grass seeds covers, for us to know how many to buy. Also, we need the area of the walkway, since it is not covered by grass

The area of a triangle is:

But, since there is a walkway that isn't covered in grass, we need to subtract the circle area from the triangle area

Area of circle:

Then the total area of the lawn :

Answer:

• a =10

• b = 4

Explanation:

An isometry is a rigid transformation that preserves length and angle measures, as well as perimeter and area.

This means that the two right triangles are congruent.

Thus, we have that:

Next, we solve for a and b.

Likewise:

The values of a and b are 10 and 4 respectively.

We have an algebraic problem where we have to solve for "w"

Solving for "w"

The previous result is the solution to the problem without simplifying, the error is that you have in the image, in the denominator the factor "23x" in reality this is "27x"

ANSWER:

A. Domain: x ≠ n

D. Range: All real numbers

STEP-BY-STEP EXPLANATION:

We have the following function:

The domain of a function is the interval of input values, that is, the interval of x while the range is the interval of output values, that is, the interval of y.

In the cotangent function, x cannot take the value of radians (nor its multiples), since it is not defined, while the range is continuous on all real numbers.

That means the correct options are:

A. Domain: x ≠ n

D. Range: All real numbers

Notice that we can draw a triangle in the square , and that the length of the square's diagonal is the same as the length of the triangle's hypotenuse. The triangle is a right triangle therefore it satisfies the Phytagorean Theorem. To calculate for it's hypotenuse , we will use:

where c is the hypotenuse, and a, b are the other legs of the triangle.

Since the hypotenuse of the triangle is 42.43 cm. Therefore, the square's diagonal is also 42.43 cm

Answer:

The square's diagonal is 42.43 cm

In any triangle, the sum of the internal angle is always up to 180º.

Then, for triangle ABC:

Option B is correct.

9.56556555... is an irrational number.

Step-by-step Explanation

Rational numbers are numbers that can be expressed as a clear fraction consisting of the numerator and the denominator both being integers.

The decimal form or decimal expansion of a rational number terminates after a particular/finite number of digits (e.g., 0.25, 0.762 etc.) or begins to repeat/recur the same sequence over and over again (e.g., 0.333..., 0.267267... etc)

Anything other than these two rules, the number is regarded as an irrational number.

The number given is 9.56556555...

The dots indicate thst the numbers after the decimal point conbtinue till eternity.

Observing the numbers after the decimal point for the given number, one can see that 565 repeats once and then the number after the second 565 is 55, indicating that the 565 doesn't recur till infinity.

Since the numbers after the decimal point doesnt contain a finite number of digits and the numbers don't recur till infinity, we can conclude that 9.56556555... isn't a rational number.

time= unknow= t1

distance = x

b) down hille

rate=4 miles per hour

time=time2=one hour less than the time to climb = t1-1

distance = x

so

replacing

Step 2

solve the equations

set t1= t1

it means the distance to the top of the mountain is 2.4 miles, so the entire hike is twice that amount
