1.4x10 -2 in standard form

The value for c is 36 which completes the square for the quadratic x² + 12x + c.

The polynomial having a degree of 2 is termed as the quadratic equation.It means that the equation will have the maximum power of 2.

Here we have the equation

=x²+12x+c

=x^2+12x+36

=x^2+6x+6x+36

=x(x+6)+6(x+6)

=(x+6)(x+6

=(x+6)²

hence value for c is 36 which completes the square for the quadratic x² + 12x + c.

Step-by-step explanation:

Answer: 12.6%

Step-by-step explanation:

403,200/3,200,000 = 0.126

0.126 = 12.6%

Answer:

Somewhere between 12 and 13, perhaps 12.25

Step-by-step explanation:

This is a (rather) simple explanation:

Look for 2 square numbers that are either side of 150

In this case, it is 144 and 169

The square root of 144 is 12 and the square root of 169 is 13

Therefore we can estimate that the square root of 150 is somewhere between 12 and 13.

As 150 is a lot closer to 144 to 169, I would estimate around 12.25 but you do not need an exact value :)

The least amount that Bill must pay to buy the tiles he needs is $292.50

The total cost of buying the tiles individually is : cost per tile x total tiles needed

$0.40 x 864 = $345.60

The total cost of buying the tiles in a box of 100 is : $32.50 x 9 = $292.50

I hope this helps you. Good luck!

Answer:

[tex] \: [/tex]

Step-by-step explanation:

In the question, it is given that a sphere has a radius of 10 cm and we have to find the volume of the sphere.

To Find the volume of the cone, we must know this formula :

[tex]\\{\longrightarrow{ \qquad{\underline{\boxed {\pmb{\frak { Volume_{(sphere) }= \dfrac{4}{3} \: \pi {r}^{3}}}}}}}} \\ \\[/tex]

Now, we will substitute the values in the formula :

[tex]\\{\longrightarrow{ \qquad{ {\pmb{\sf { Volume_{(sphere) }= \dfrac{4}{3} \: \times 3.14 \times {(10)}^{3}}}}}}} \\ \\[/tex]

[tex]\\{\longrightarrow{ \qquad{ {\pmb{\sf { Volume_{(sphere) }= \dfrac{4}{3} \: \times 3.14 \times 1000}}}}}} \\ \\[/tex]

[tex]\\{\longrightarrow{ \qquad{ {\pmb{\sf { Volume_{(sphere) }= \dfrac{4}{3} \: \times 3140}}}}}} \\ \\[/tex]

[tex]\\{\longrightarrow{ \qquad{ {\pmb{\sf { Volume_{(sphere) }= \dfrac{4 \times 3140}{3} }}}}}} \\ \\[/tex]

[tex]\\{\longrightarrow{ \qquad{ {\pmb{\sf { Volume_{(sphere) }= \dfrac{12560}{3} }}}}}} \\ \\[/tex]

[tex]\\{\longrightarrow{ \qquad{ {\pmb{\sf { Volume_{(sphere) }= 4186.6 }}}}}} \\ \\[/tex]

Therefore,

Given :

To Find :

Solution :

As we know that volume of sphere is calculated by the formula :

Here,

Putting the values in the formula,

>> V = (4 / 3) × (22 / 7) × (10)³

>> V = (4 / 3) × (22 / 7) × (10 × 10 × 10)

>> V = (4 / 3) × (22 / 7) × (10 × 100)

>> V = (4 / 3) × (22 / 7) × 1000

>> V = 4 × 22 × 1000 / 3 × 7

>> V = 88 × 1000 / 3 × 7

>> V = 88000 / 3 × 7

>> V = 88000 / 21

>> V = 4190.47 cm³

Answer:

Step-by-step explanation:

Step-by-step explanation:

your a. is wrong.

so, we need to do both.

a.

you did not really read carefully. DE = 4x and not 4.

DE = 4x does not mean x = 4. absolutely not.

so, you cannot just use x=4 in the first triangle.

but you are right, AB and DE correlate between the 2 congruent triangles.

therefore

3x + 6 = 4x

6 = x

so, AB = 3x + 6 = 3×6 + 6 = 18 + 6 = 24 ft

b.

congruent means that the sides and the angles are the same between the 2 triangles.

so,

6y + 12 = 8y + 2

12 = 2y + 2

10 = 2y

y = 5

so, the angle EDF is

8y + 2 = 8×5 + 2 = 40 + 2 = 42°

I hope this Helps! ;)

Answer:

y=4x+4

Step-by-step explanation:

using y=mx+b, y is y since we are writing a function. 4 would be the slope, as that is added per minute, so that takes the place of m, and x stays the same, which leaves b, the y intercept, to be 4. this is because the barrel already had 4 gallons inside before.

Step-by-step explanation:

so,

x²y³ = 10

x³y² = 8

what is the value of x⁵y⁵ ?

don't you see right away that 2+3 and 3+2 both equal 5 ?

so, x³x² = x⁵

y²y³ = y⁵

so, I only need to multiply both equations with each other. and I get

x²y³×x³y² = 10×8

x⁵y⁵ = 80

why ? because multiplications and exponents (which are nothing else than multiplications) are all communicative :

a×b = b×a.

Answer:

11

Step-by-step explanation:

First, order the numbers in the given set from least to greatest:

8 , 9 , 9 , 10 , 12 , 14 , 15 , 15

The median is the number found in the middle of the given set. If the amount of numbers in the set are even (as in this case), then you will find the mean of the two middle numbers.

In this case, the middle numbers are 10 & 12:

Find the mean. The mean is found by adding all the numbers together and dividing by the amount of numbers there is:

(10 + 12)/2 = (22)/2 = 11

11 is your median.
