What number should be added to both sides of the equation to complete the square? x-^2+8x=4

Answer:

V = 251.3

Step-by-step explanation:

Volume of a Cone formula:

V = πr²(h/3)

Given:

r = 4.9

h = 10

Work:

V = πr²(h/3)

V = 3.14(4.9²)(10/3)

V = 3.14(24.01)(10/3)

V = 251.3

Answer:

x=5

Step-by-step explanation:

0=15-3x, then -15=-3x, divide the -15 by-3 and the answer is x=5

Answer:

x=158

Step-by-step explanation:

Answer:

Step-by-step explanation:

IT is either the same as 7x+4 because it is infront of each other or you add 8x+6 and 6x+2 then you substract that from 180 to find out the remaining angle. Of course you have to subtitute the amount of x first.

Answer:

The diameter decreases at a rate of 0.053 cm/min.

Step-by-step explanation:

Surface area of an snowball

The surface area of an snowball has the following equation:

[tex]S_{a} = \pi d^2[/tex]

In which d is the diameter.

Implicit differentiation:

To solve this question, we differentiate the equation for the surface area implictly, in function of t. So

[tex]\frac{dS_{a}}{dt} = 2d\pi\frac{dd}{dt}[/tex]

Surface area decreases at a rate of 3 cm2/min

This means that [tex]\frac{dS_{a}}{dt} = -3[/tex]

Tind the rate (in cm/min) at which the diameter decreases when the diameter is 9 cm.

This is [tex]\frac{dd}{dt}[/tex] when [tex]d = 9[/tex]. So

[tex]\frac{dS_{a}}{dt} = 2d\pi\frac{dd}{dt}[/tex]

[tex]-3 = 2*9\pi\frac{dd}{dt}[/tex]

[tex]\frac{dd}{dt} = -\frac{3}{18\pi}[/tex]

[tex]\frac{dd}{dt} = -0.053[/tex]

The diameter decreases at a rate of 0.053 cm/min.

Step-by-step explanation:

Answer: greater than 0.3

Step-by-step explanation:

On edge

The margin of error for a 95% confidence level will be greater than 0.3.

A random population parameter is likely to be included in a confidence interval, which is a range of values that is limited by the statistic's mean. The confidence level is the percentage of probability, or certainty, that, after repeated random sample draws, the confidence interval would include the true population parameter.

Given:

A confidence level is 95%.

The formula to calculate the margin of error:

The margin of error = Z x S/√n.

Where S is the standard deviation and n is the sample size.

The corresponding z-score of the confidence level is 95%.

So, the margin of error will be always greater than 0.3.

Therefore, the margin of error will be always greater than 0.3.

Answer:

A) By using the Pythagorean Theorem, we will see that [tex]8^2 + 15^2 = 17^2[/tex]. If we simplify it, we will find that the hypotenuse of Δ[tex]ABC = 17[/tex]

B) approximately [tex]18.79[/tex]

Step-by-step explanation:

A) In all honesty, you don't really need to look at ΔACD at all for this one. Just use the Pythagorean Theorem (like previously stated) and solve!

***Pythagorean Theorem is  [tex]leg^2 + leg^2 = hypotenuse^2[/tex]

B) Here, you can also use the Pythagorean Theorem! However this time, the equation will be, [tex]8^2 + 17^2 = AD[/tex].

Answer:

2/5

Step-by-step explanation:

IXl answer

The experimental probability that the next drink sold will be a mocha is 2/5.

Number of mochas =4

Total drinks =10

Probability is the quantification of possibilities.

P(event) = Favorable outcomes/ Total outcomes

P(mocha) = 4/10

P(mocha) =2/5 =0.4 or 40%

Thus, the experimental probability that the next drink sold will be a mocha is 2/5.
