Answers

Answer:

Step-by-step explanation:

6x² +9x +3  , divide all terms by 6 to have the first term with coefficient 1

x² + (9/6)x + (3/6) , simplify the fractions

x² + (3/2)x + (1/2)

Round off 245,13589 to four decimal places​

Answers

245,13589 rounded to four decimal places equals 24,513,589.0000

Rounding off is basically a approximate value written in compact form for our convenience when precise  accurate result is not that necessary.

What is a decimal ?

A decimal is a point or a dot separating the whole part and the fractional part of the number.Now rounding off numbers to certain decimal places has a condition if the digits just after the decimal is more than half we take the upper value if itis less than half we take the lower value.

Given in this question let's go by rounding off from 1 place to 4 for better understanding.

rounding off 24513589 to one decimal place = 2451359.0

rounding off 2451359.0 to one decimal place = 245136.0

rounding off 245136.0 to one decimal place = 24514.0

rounding off 24514.0 to one decimal place  = 2451.0

When graphed, the circle with equation
2x² + y2 + 14x + 8y + 20 = 0
Will lie ENTIRELY in Quadrants…

Answers

Answer:

First we must use the property of the sum of perfect squares:

X^2 -14x +y^2 +10y+65 =0

Adding 7^2 and -7^2

x^2 -14x+7^2-7^2 +y^2+10y+65=0

x^2 -2.7x +7^2 -49 +y^2+10y+65=0

(X-7)^2 +y^2+10y+16=0

Adding 5^2 and -5^2

(X-7)^2 +y^2 +10y+5^2-5^2+16=0

(X-7)^2 +y^2+2.5y+5^2 -25 +16=0

(X-7)^2+ (y+5)^2 -9 = 0

(X-7)^2 +(y+5)^2 = 9

(X-7)^2+(y+5)^2 = 3^2

Which statements correctly describe the graph of the function f(x) = x3 – 2x2 – 19x 20? Select three options.

Answers

The graph of the function f(x) = x³ – 2x² – 19x + 20 passes through the  x-axis at  –4, 1, and 5.

What is a factorization?

It is the method to separate the polynomial into parts and the parts will be in multiplication. And the value of the polynomial at this point will be zero.

The function is given as

f(x) = x³ – 2x² – 19x + 20

By hit and trial. Let x = 1, we have

f(x) = 1³ – 2(1)² – 19(1) + 20 = 0

Then the equation will be

f(x) = (x – 1)(x² – x – 20)

f(x) = (x – 1)(x – 5)(x + 4)

Then the graph of the function passes through x-axis at  –4, 1, and 5.

The graph is shown below.

Answers

Answer:

Step-by-step explanation:

As you know, a student ticket is one item, and you only need one of these to enter a football game. We will assume he is by himself and without friends. There are items he can buy for $2 each at the concession stand.

With what we know, we can conclude that the total cost to attend the football game could be a function.

The function will be

f(x) = 2x + 5

This is because you buy the ticket one time and buys x items, which is modeled by the function.

Samuel is running a 3-mile race. He would like to finish the race in under 33 minutes. He has already run for 10. 5 minutes. The inequality 10. 5 x < 33 represents the situation. Solve the inequality. How is the solution interpreted in the context of the problem? x < 22. 5; Sam has a maximum of 22. 5 minutes left to finish running. X < 22. 5; Sam has fewer than 22. 5 minutes left to finish running. X > 43. 5; Sam has at least 43. 5 minutes left to finish running. X < 43. 5; Sam has no more than 43. 5 minutes left to finish running.

Line K has the equation 9x-4y=-5x4.
Line L is parallel to line K, but line L passes through the point (4,7).
The equation for L in slope-intercept form is_______

Answers

Answer:

y = (9/4)x + 2, given that I've assume the correct meaning of "-5x4."

Step-by-step explanation:

A parallel line has the same slope as the reference line,

The reference line is 9x-4y = -5x4, as written.  I'm not sure the 4 belongs, but I'll assume it is written correctly.  I'm not sure if the term -5x4 is meant to mean -5x^4, -20x or -20.  I'll assume -20:

9x-4y = -20

Put the equation into standard slope-intercept form:  Y = mx + b, where m is the slope and b is the y-intercept (the value of y when  x = 0).

-4y = -9x - 20

y = (9/4)x + 5

This line has a slope of (9/4).  The parallel line will have the same slope.

y = (9/4)x + b

We can find a value of b that would shift this line to include (4,7) by using this point in the equation:

y = (9/4)x + b

7 = (9/4)(4) + b

7  = 9 + b

b = 2

The equation of a line parallel to the reference line is y = (9/4)x + 2
