Answer:

150.7

Step-by-step explanation:

Formula for volume of a cone = \pi r^2\frac{h}{3}

where r = radius and h = height

We are given the diameter ( 8yds ) and the height ( 9yds )

In order to find the volume we need to find the radius

We can do this my dividing the diameter by 2 ( this is because the radius is equal to half the length of the diameter)

8/2 =4

So the radius is equal to 4yds

Now we plug in the values into the formula

( remember it says use 3.14 for π )

V=(3.14)4^2\frac{9}{3} \\4^2=16\\16*3.14=50.24\\\frac{9}{3} =3\\3*50.24=150.72

Finally we round to the nearest tenth and get that the answer is 150.7yd²

Answer:

D

Step-by-step explanation:

(f • g)(x)

= f(x) × g(x)

= (x + 4)(3x² - 7)

each term in the second factor is multiplied by each term in the first factor , that is

x(3x² - 7) + 4(3x² - 7) ← distribute both parenthesis

= 3x³ - 7x + 12x² - 28

= 3x³ + 12x² - 7x - 28 ← in standard form

What equation is solved by the graphed systems of equations? Two linear equations that intersect at the point negative 1, negati
GuDViN [60]

To solve this problem, we have to manually solve for the value of x for each choices or equations. The correct equation will give a value of -1 since the linear equations intersects at point (-1, -4).

<span>1st: 7x + 3 = x + 3</span>

7x – x = 3 – 3

6x = 0

<span>x = 0                (FALSE)</span>

 

<span>2nd: 7x − 3 = x – 3</span>

7x – x = 3 – 3

6x = 0

<span>x = 0                (FALSE)</span>

           

<span>3rd: 7x + 3 = x − 3</span>

7x – x = - 3 – 3

6x = -6

<span>x = -1               (TRUE)</span>

 

<span>4th: 7x − 3 = x + 3</span>

7x – x = 3 + 3

6x = 6

<span>x = 1                (FALSE)</span>

 

Therefore the answer is:

<span>7x + 3 = x − 3</span>

What is the common ratio between successive terms in the sequence<br> 2,4,8,-16, 32, 64,
marysya [2.9K]

Answer: The sequence does not have common ratio.

Step-by-step explanation:

By definition, a sequence with a constant ratio (common ratio) between terms is called a "Geometric sequence". In order to find the common ratio, it is necessary to divide any term in the sequence by the previous term.

In this case, given the sequence:

2,4,8,-16, 32, 64,

We get:

4\div2=2\\\\8\div4=2\\\\-16\div8=-2\\\\32\div(-16)=-2\\\\64\div32=2

Since the ratios between the terms are not constant, we can conclude that <em>the sequence does not have common ratio.</em>
