What is the volume, in cubic feet, of a cone that has a base
7T
area of
square feet and a height of 3 feet?
4.

Answer:

x ≈ - 4.12 , x ≈ 0.12

Step-by-step explanation:

2x² + 8x - 1 = 0 ( add 1 to both sides )

2x² + 8x = 1 ( factor out 2 from the first two terms )

2(x² + 4x) = 1

To complete the square

add/ subtract ( half the coefficient of the x- term )² to x² + 4x

2(x² + 2(2)x + 4 - 4) = 1

2(x + 2)² - 8 = 1 ( add 8 to both sides )

2(x + 2)² = 9 ( divide both sides by 2 )

(x + 2)² = [tex]\frac{9}{2}[/tex] ( take square root of both sides )

x + 2 = ± [tex]\sqrt{\frac{9}{2} }[/tex] = ± [tex]\frac{3}{\sqrt{2} }[/tex] ( subtract 2 from both sides )

x = - 2 ± [tex]\frac{3}{\sqrt{2} }[/tex]

Then

x = - 2 - [tex]\frac{3}{\sqrt{2} }[/tex] ≈ - 4.12 ( to 2 dec. places )

x = - 2 + [tex]\frac{3}{\sqrt{2} }[/tex] ≈ 0.12 ( to 2 dec. places )

Answer:

(v)= 0.75+12.75

Step-by-step explanation:

if the cost to rent a video game is 0.75 then you put the .75 after the (v) because each video costs 0.75 to rent, then it says she paid another cost to an initiation fee, so you then add that cost onto the rent fee.

Answer:

$13.09

Step-by-step explanation:

     If Kelly buys 3.5 gallons of gas, we can multiple each gallon by the price of the gas since the cost is given to us price per gallon.

3.5 gallons * $3.74 = $13.09

Answer: 1012 calories

Step-by-step explanation:

Shannon burns 46 calories each hour while sleeping.

When she plays basketball, she burns 11 times as many calories as she does when sleeping. The amount of calories burnt when she plays basketball will be:

= 11 × 46

= 506 calories

She burns twice as many calories each hour when she runs than when she plays basketball. The amount of calories burnt when she runs will be:

= 2 × 506 calories

= 1012 calories

The amount of calories that Shannon burn when she runs for 1 hour will be 1012 calories

Answer:

Rs. 83.33

Step-by-step explanation:

cost of a pen = Total cost / total quantity

= 100/10

= Rs. 8.33/pen

Total cost for 10 pens = Cost per pen x quantity

= Rs.8.33 x 10

= Rs. 83.33 Ans

Answer:

Is it 0 ? im not sure

Step-by-step explanation:

Answer: 1) Zero

2) B. None

Step-by-step explanation: The slope of any horizontal or vertical straight line is always going to be zero because it stays constant.

There are no zeros of the linear function because it does not cross the x-axis.

This will take roughly 3 minutes,

First i'm assuming this is an arithmetic sequence since using the recurring formula;

156250=781250+d

where d is the common difference

d=-625000

Using the implicit relation we can then say;

u(N)=u⁰+nd

where are looking for u⁷ since our first term is u⁰, second is u¹....8th is u⁷

u(7)=781250-6250000

u(7)=-5868170

No it's not 10 if this is arithmetic sequence.

If this sequence is geometric then,

r=156250/781250

r=1/5

So we're diving by 5

we can use the implicit relation which states:

u(n)=u⁰r^n

u(7)=781250×1/5^7

u(7)=10

THIS IS A GEOMETRIC SEQUENCE AND THE 8TH TERM IS 10 SO THIS THIS TRUE HURYY

1.First = Seven over four and three over eight

because The denominators of 9 and 3 were not divisible by any of the tenths, hundredths, thousandths, etc.

Step-by-step explanation:

A terminating decimal, true to its name, is a decimal that has an end. For example, 1 / 4 can be expressed as a terminating decimal: It is 0.25. In contrast, 1 / 3 cannot be expressed as a terminating decimal, because it is a recurring decimal, one that goes on forever. In other words, as a decimal 1/3 is 0.33333…..

Answer:

B

Step-by-step explanation:

The end behavior of a function is how the graph behaves as it approaches negative and positive infinity.

Let's take a look at each end.

As x approaches negative infinity:

As x approaches the left towards negative infinity, we can see that the graph is shooting straight upwards.

Therefore, as [tex]x\rightarrow-\infty[/tex], our function f(x) is increasing and increasing up towards positive infinity.

Therefore, the end behavior at the left will be:

[tex]\text{As } x\rightarrow-\infty, f(x)\rightarrow\infty[/tex]

As x approaches (positive) infinity:

As x approaches the right towards positive infinity, we can see the that graph is also shooting straight upwards.

Therefore, the end behavior will be exactly the same. As x approaches positive infinity, f(x) also approaches positive infinity.

Therefore, the end behavior at the right will be:

[tex]\text{As } x\rightarrow \infty, f(x)\rightarrow \infty[/tex]

Therefore, our answer is B.
