Use the remainder theorem to divide 5x^2+9x-2 by x+3. what is the remainder?
A)16
B)-44
C)-20
D)40

Answers

Answer 1

Answer:

A)16

Step-by-step explanation:

Given

f(x)=5x^2+9x-2

Remainder theorem states that when f(x) is divided by x-a then the remainder can be calculated by calculating f(a).

Now Using the remainder theorem to divide 5x^2+9x-2 by x+3 to find the remainder:

f(x)=5x^2+9x-2

f(-3) = 5(-3)^2 +9(-3) -2

       =5(9) - 27 -2

       = 45-29

       = 16 !

Answer:

h = 3πx

Step-by-step explanation:

The volume (V) of the cylinder is calculated using the formula

V = πr²h ( r is the radius and h the height )

V = π × x² × 3x = 3πx³

The volume of the cuboid therefore has volume of 3πx³, that is

x × x × h = 3πx³

x²h = 3πx³ ( divide both sides by x² )

h = 3πx³ ÷ x² = 3πx

The length of a rectangle is 9 cm and width of the rectangle is 5 cm.

What is Area of Rectangle?

The area of Rectangle is length times of width.

Length of a rectangle is 11 centimeters less than four times its width.

Length=4W-11

Width=W

Area=45

Area=Length×Width

=(4w-11)w

45=4w²-11w

4w²-11w-45=0

After applying a =4, b=-11 and c=-45 in the quadratic formula

we get w=5

Plug in the value of w in length

Length=4W-11

=4(5)-11

=20-11

=9

Hence, the length of a rectangle is 9 cm and width of the rectangle is 5 cm.

solve by completing the square x^2+12x+32=0​

Answers

Answer:

hello : x = - 4 or x = - 8

Step-by-step explanation:

x²+12x+32=0​

(x² +2(6)(x) +6²) - 6² +32 = 0....by completing the square

(x + 6 )²- 2² = 0

(x+6-2)(x+6+2)=0 by idetity : a² - b² = (a - b ) ( a + b )

(x+4)(x+8) =0

x+4=0 or x+8= 0

x = - 4 or x = - 8

Answer:

x = - 8, x = - 4

Step-by-step explanation:

Given

x² + 12x + 32 = 0 ( subtract 32 from both sides )

x² + 12x = - 32

To complete the square

add (half the coefficient of the x- term)² to both sides

x² + 2(6)x + 6² = - 32 + 6²

(x + 6)² = - 32 + 36 = 4

Take the square root of both sides

x + 6 = ± 2 ( subtract 6 from both sides )

x = - 6 ± 2

Hence

x = - 6 - 2 = - 8

x = - 6 + 2 = - 4

If y varies inversely with x and y =5 when x=2.5 what is the value of y when x=20

Answers

Answer:

If x = 20, then y = 12.5/20 = 0.625

Step-by-step explanation:

The pertinent relationship is y = k/x, where k is the constant of proportionality.

Subbing 5 for y and 2.5 for x yields 5 = k/2.5, so k = 12.5.

Then the specific relationship fit to this problem is y = 12.5/x.

If x = 20, then y = 12.5/20 = 0.625

The equation for the circle is:

x²+y²+14x+10y−7=0 .


What is the center of the circle?

Answers

Answer:

(-7,-5)

Step-by-step explanation:

Converting the circle into the form (x-h)^2+(y-k)^2=r^2, we get

x^2+14x+49+y^2+10y+25=7+25+49

So we get

(X+7)^2+(y+5)^2=81

So the center of the circle is (-7,-5)

Answer:

centre = (- 7, - 5)

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

Arrange the equation by placing the x and y terms together

x² + 14x + y² + 10y - 7 = 0 ( add 7 to both sides )

x² + 14x + y² + 10y = 7

Use the method of completing the square

add (half the coefficient of the x/y term)² to both sides

x² + 2(7)x + 7² + y² + 2(5)y + 5² = 7 + 7² + 5²

(x + 7)² + (y + 5)² = 7 + 49 + 25 = 81 ← in standard form

with (h, k) = (- 7, - 5) ← centre of circle

Answer:

[tex]y=-2x^2 -16x -28[/tex]

Step-by-step explanation:

We are given with the graph of a parabola

[tex]y=-2x^2 + 3x -5[/tex]

a=-2, b=3 and c=-5

Discriminant = [tex]b^2-4ac= 3^2 -4(-2)(-5)= 9-40= -31[/tex]

Discriminant is negative so x intercepts are imaginary.

In the graph we have two x intercepts.

[tex]y=-2x^2 -4x -2[/tex]

a=-2, b=-4 and c=-2

Discriminant = [tex]b^2-4ac= (-4)^2 -4(-2)(-2)=0[/tex]

Discriminant is 0 so there is only one x intercept

[tex]y=-2x^2 -16x -28[/tex]

a=-2, b=-16 and c=-28

Discriminant = [tex]b^2-4ac= (-16)^2 -4(-2)(-28)=32[/tex]

Discriminant is positive so there  are two x intercepts

[tex]x=\frac{-b+-\sqrt{b^2-4ac} }{2a} =\frac{16+-\sqrt{32} }{2(-2)}[/tex]

We will get two values for x

x= -5.414  , x=-2.586

Two x intercepts are negative . That is the x intercepts of given graph.

[tex]y=-2x^2 +16x -28[/tex]

a=-2, b=16 and c=-28

Discriminant = [tex]b^2-4ac= (16)^2 -4(-2)(-28)=32[/tex]

Discriminant is positive so there  are two x intercepts

Which are the solutions of x2 = –11x + 4?

Answers

Answer:

x =  0.35   or x = -11.35

Step-by-step explanation:

Points to remember

Solution of a quadratic equation ax² + bx + c = 0

x = [-b ± √(b² - 4ac)]/2a

It is given that,  x² = –11x + 4

x² + 11x - 4 = 0

To find the solution

Here a = 1, b = 11 and c = -4

x = [-b ± √(b² - 4ac)]/2a

x = [-11 ± √(11² - 4 * 1 * (-4))]/2*1

 =  [-11 ± √(121 + 16)]2

 = [-11 ± √137]/2

 = [-11 ± 11.70]/2

x = -11 + 11.70  or x = -11 - 11.70

x =  0.35   or x = -11.35

The number of tickets sold is an example of continuous data. True or False?

Answers

Answer:

False

Step-by-step explanation:

Continuous data is data that can take any value within a range, including non-whole number values.

Because the number of tickets sold can only take whole number values, it is not an example of continuous data.

False

I hope this helps you understand continuous data. Have a great day. :)

Answer: False

Step-by-step explanation: Continuous data is data that can be measured. The number of tickets that were sold would only be positive integers meaning that there can't be a fraction of a ticket sold. Since discrete data is data that can be counted, the number of tickets sold would be an example of data that is discrete.

Jolene invests her savings in two bank accounts, one paying 6 percent and the other paying 9 percent simple interest per year. She puts twice as much in the lower-yielding account because it is less risky. Her annual interest is 7266 dollars. How much did she invest at each rate?

Amount invested at 6 percent interest is $
Amount invested at 9 percent interest is $

Answers

Answer:

Amount invested at 6 percent interest is $69,200

Amount invested at 9 percent interest is $34,600

Step-by-step explanation:

Let the amount invested (or principal) at 6 percent interest be $2x

The principal(P) (amount invested) at 9 percent interest will be $x

Amount(A) = P(1 + rt)

Time(t) = one year = 1

Amount at 6% interest = 2x(1 + 0.06) = $2.12x

Interest accumulated = Amount - Principal = $2.12x - $2x = $0.12x

Amount at 9% interest = x(1 + 0.09) = $1.09x

Interest accumulated = Amount - Principal = $1.09x - $x = $0.09x

Total interest = $7,266

So, $0.12x + $0.09x = $7,266

$0.21x = $7,266

x = [tex]\frac{7,266}{0.21}[/tex] = $34,600

The principal (amount invested) at 9 percent interest rate is $34,600

The principal (amount invested) at 6 percent interest rate is 2 × $34,600 = $69,200

What is the expression (3x²y³) ³​

Answers

Final answer:

The expression (3x²y³) ³ is found by cubing the coefficient and multiplying each variable's exponent by 3, which results in 27x⁶y⁹.

Explanation:

When we deal with the cubing of exponentials, as in the expression (3x²y³) ³, both the numerical coefficient and the variables with their exponents are raised to the power of 3. The rules of exponents guide us to cube the number 3 and multiply the exponents of x and y by 3.

To cube the number 3, we would calculate 3³, which equals 27. For the variables, we apply the exponent to each exponent: x raised to the 2³ (which is 6) and y raised to the 3³ (which is 9). Hence, the expression (3x²y³) ³ simplifies to 27x⁶y⁹. This demonstrates that when cubing an exponential expression, we obtain a new exponent for each variable by multiplying the original exponent by 3, and we cube the numerical coefficient as well.
