X^2-15x+56=(x-7)(x-____)
Fill in the blank please help me

Answers

Answer 1

Answer:

8

Step-by-step explanation:

Answer 2

The required value in the fill-in-the-blank is 8, which is completely factored into the product of two binomials: (x-7) and (x-8).

To fill in the blank in the expression x²-15x+56=(x-7)(x-____), we need to find the missing factor that, when multiplied by (x-7), gives us the original quadratic expression.

Factor the quadratic expression x²-15x+56 by finding two numbers that multiply to 56 and add up to -15, which are -7 and -8.

Therefore, we can rewrite the quadratic expression as:

x² - 15x + 56 = (x - 7)(x - 8)

This means that the quadratic expression can be completely factored into the product of two binomials: (x-7) and (x-8).

Thus, the required value in the fill-in-the-blank is 8.

Whats is the equation of the following line?

Answers

D. Y= - 4/3 x Rise over run

Answer:

The equation of the line is:

  C.     [tex]y=\dfrac{-3}{4}x[/tex]

Step-by-step explanation:

The line passes through the point (0,0) and (4,-3).

By using the two point formula to find the equation of the line.

i.e. any line passing through two points (a,b) and (c,d) is calculated by using the formula:

[tex]y-b=\dfrac{d-b}{c-a}\times (x-a)[/tex]

Here (a,b)=(0,0) and (c,d)=(4,-3)

Hence, the equation of line is calculated as follows:

[tex]y-0=\dfrac{-3-0}{4-0}\times (x-0)\\\\i.e.\\\\y=\dfrac{-3}{4}\times x\\\\i.e.\\\\y=\dfrac{-3}{4}x[/tex]

Hence, the correct answer is:  Option: C

Solve for t.

-5 − 2t = 3t

Answers

t is equal to -1.Add 2t to both sides of the equation. -5 = 5tDivide both sides of the equation by -5. 1 = -tMultiply both sides of the equation by -1. -1 = t

First, we have to isolate the t, or keep it by itself, to solve. To do that, we need to move everything with t in it to on side.

-5 - 2t + 2t = 3t + 2t

The -2t and + 2t cross out, leaving us with t on one side, which is exactly what we want!

-5 = 5t

But t isn't alone yet. We need to get rid of its five. To do that, we need to use the same process: use the opposite symbol. In 5t, 5 is being multiplied by t. To get rid of, we need to divide 5. BUT the mega rule in algebra... what you do to one side you must do to the other, or else the equation would not be true anymore, so...

-5/5 = 5t/5

-1 = t

A gas at 89°C occupies a volume of 0.67 L. At what Celsius temperature will the volume increase to 1.12 L?

Answers

Answer:

V1 / T1 = V2 / T2

0.67 / (273 + 89) = 1.12 / (273 + t )

t = 332 °C

The temperature will be 332°C.

Given values:

Volume,

[tex]V_1 = 0.67 \ L[/tex][tex]V_2 = 1.12 \ L[/tex]

Temperature,

[tex]T_1 = 89^{\circ} C \ or \ 362 \ K[/tex][tex]T_2 = \ ?[/tex]

We know the relation,

→ [tex]\frac{V_1}{T_1} = \frac{V_2}{T_2}[/tex]

By substituting the values, we get

→ [tex]\frac{0.67}{362} = \frac{1.12}{T_2}[/tex]

→   [tex]T_2 = \frac{1.12\times 362}{0.67}[/tex]

          [tex]= 332^{\circ} C[/tex]

IQR: 48

MAD: 23.75

Paul:

Mean: 1929

Median: 1929.5

range: 15

IQR: 6

MAD: 3.5

Step-by-step explanation:

For the Derek's collection:

1.  Mean =  1930.375

2. Median =  1930

For the Paul's collection:

1.  Mean = 1929.75

2. Median = 1931

For Derek's collection:

Mean:

Add up all the numbers and divide by the total number of numbers:

Mean = (1950 + 1952 + 1908 + 1902 + 1955 + 1954 + 1901 + 1910) / 8

          = 1930.375

Median:

The median is the middle value of the set, so we first need to put the numbers in order:

1901, 1902, 1908, 1910, 1950, 1952, 1954, 1955

The median is the average of the middle two numbers, which are 1910 and 1950:

Median = (1910 + 1950) / 2

             = 1930

For Paul's collection:

Mean:

Add up all the numbers and divide by the total number of numbers:

Mean = (1929 + 1935 + 1928 + 1930 + 1925 + 1932 + 1933 + 1920) / 8

          = 1929.75

Median:

The median is the middle value of the set, so we first need to put the numbers in order:

1920, 1925, 1928, 1929, 1930, 1932, 1933, 1935

The median is the average of the middle two numbers, which are 1930 and 1932:

Median = (1930 + 1932) / 2

factor completely x^3 + 1/8

Answers

Answer:

((2 x + 1) (4 x^2 - 2 x + 1))/8

Step-by-step explanation:

Factor the following:

x^3 + 1/8

Put each term in x^3 + 1/8 over the common denominator 8: x^3 + 1/8 = (8 x^3)/8 + 1/8:

(8 x^3)/8 + 1/8

(8 x^3)/8 + 1/8 = (8 x^3 + 1)/8:

(8 x^3 + 1)/8

8 x^3 + 1 = (2 x)^3 + 1^3:

((2 x)^3 + 1^3)/8

Factor the sum of two cubes. (2 x)^3 + 1^3 = (2 x + 1) ((2 x)^2 - 2 x + 1^2):

((2 x + 1) ((2 x)^2 - 2 x + 1^2))/8

1^2 = 1:

((2 x + 1) ((2 x)^2 - 2 x + 1))/8

Multiply each exponent in 2 x by 2:

((2 x + 1) (2^2 x^2 - 2 x + 1))/8

2^2 = 4:

Answer:  ((2 x + 1) (4 x^2 - 2 x + 1))/8

[tex]x^3+\dfrac{1}{8}=\\ \\ =x^3+2^{-3} = \\ \\ =x^3+(2^{-1})^3 =\\ \\ = (x+2^{-1})(x^2-2^{-1}x+2^{-2}) = \\ \\ = \Big(x+\dfrac{1}{2}\Big)\Big(x^2-\dfrac{x}{2}+\dfrac{1}{4}\Big)\\ \\ \\ \boxed{a^3+b^3 = (a+b)(a^2-ab+b^2)}[/tex]

A cake is shaped like a cylinder with a diameter of 9 in. The height of the cake is 6 in.
What is the exact volume of the cake?
Enter your answer in the box.

pi in^3

Answers

Answer: 121.5 pi in^3 or 381.7 in^3

Step-by-step explanation:

Volume of a cylinder = pi r^2(h)

Radius = 4.5 in, Height = 6 in

pi (4.5)^2(6)

pi(20.25)(6)

121.5 pi in^3 or 381.7 in^3

The exact volume of a cylindrical cake with a diameter of 9 inches and a height of 6 inches is 121.5π cubic inches.

The volume of a cylinder can be found using the formula V = πr^2h, where V stands for volume, r is the radius of the base of the cylinder, and h is the height of the cylinder. Given the diameter of the cake is 9 inches, the radius is half of that, which is 4.5 inches. Therefore, the exact volume of the cake is calculated as follows:

V = π × (4.5 )² ×2 × 6

Which simplifies to:

V = π × 20.25 ×2 × 6

So, the exact volume of the cake is:

V = 121.5π  in^3

Solve for n. n + 1 = 4(n – 8) n = 1 n = 8 n = 11 n = 16

Answers

Answer:

The correct option is C) n= 11.

Then you can use the distributive property to multiply each term in the first binomial by each term in the second binomial. Louise also could have used the formula for a perfect square trinomial, which is found by squaring a binomial.

Answers

Answer:

Louise is missing the term [tex]30x^3[/tex]

Step-by-step explanation:

Remember that the formula for squaring a binomial is:

Where

[tex]a[/tex] is the first term of the binomial

[tex]b[/tex] is the second term of the binomial

Our binomial is [tex](5x^3+3)^2[/tex], so [tex]a=5x^3[/tex] and [tex]b=3[/tex].

Replacing values

[tex](5x^3+3)^2=(5x^3)^2+2(5x^3)(3)+3^2[/tex]

[tex](5x^3+3)^2=5^2x^6+6(5x^3)+9[/tex]

[tex](5x^3+3)^2=25x^6+30x^3+9[/tex]

Answers

Answer:

(1), (3)

Step-by-step explanation:

5.  If m starts at 1, a geometric series has the form a₁ (r)ᵐ⁻¹.

If m starts at 0, a geometric series has the form a₀ (r)ᵐ.

Here, m starts at 0.  The first term, a₀, is 150.  The temperature is decreasing, so we're looking for an r < 1.  Therefore, the answer must be (1) 150 (0.85)ᵐ.

7.  A quadratic written in vertex form is:

y = a(x - h)² + k

We can find the vertex of the parabola using x = -b/(2a).

x = -12 / (2*3)

x = -2

f(-2) = 3(-2)² + 12(-2) + 11

f(-2) = -1

So the vertex (h, k) is at (-2, -1).

Therefore, the answer must be f(x) = 3(x + 2)² - 1

We can also show this by completing the square.

f(x) = 3x² + 12x + 11

f(x) = 3(x² + 4x) + 11

f(x) = 3(x² + 4x + 4) - 3(4) + 11

f(x) = 3(x + 2)² - 1

Write the equation of the circle shown here.

Answers

Answer:

(x − 7)² + (y + 2)² = 52

Step-by-step explanation:

The equation of a circle is:

(x − h)² + (y − k)² = r²

where (h, k) is the center and r is the radius.

We know that (h, k) = (7, -2).  But we need to find the radius.  To do that, find the distance from the center to a point on the edge:

r² = (x₁ − x₂)² + (y₁ − y₂)²

r² = (7 − 1)² + (-2 − -6)²

r² = 6² + 4²

r² = 36 + 16

r² = 52

So the equation of the circle is:

(x − 7)² + (y + 2)² = 52

Final answer:

The equation of the circle is (x-2)^2 + (y-(-3))^2 = 5^2.

Explanation:

To write the equation of a circle, we need to know the center and the radius of the circle. We can see from the diagram that the center of the circle is the point (2, -3), and the radius is 5 units.

The equation of a circle is given by the formula (x-h)^2 + (y-k)^2 = r^2,

where (h, k) is the center and r is the radius. Therefore, the equation of the circle is (x-2)^2 + (y-(-3))^2 = 5^2.
