Answer:

Step-by-step explanation:

f(9)=5(9-3)(9-2)

=5*6*7

=210

Answer:

f(9) = 210

Step-by-step explanation:

In f(x) = 5(x-3)(x-2), replace each instance of x with 9:

f(9) = 5(9-3)(9-2), or:

       =5(6)(7) = 210

Pick the last choice.

Answer: 7238.2[tex]ft^3[/tex]

Step-by-step explanation:

The formula for a sphere's volume is  [tex]V=\frac{4}{3} \pi r^3[/tex].

Substitute r = 12 in the formula: [tex]V=\frac{4}{3} \pi (12)^3[/tex]

Then calculate (type the right side of the equation above in your calculator), and you will get an answer of 2304π. When you simplify further, you get 7238.22947. Rounded to the nearest tenth, it is 7238.2.

∴, the volume of the sphere is 7238.2[tex]ft^3[/tex], to the nearest tenth.

*note: it's [tex]ft^3[/tex] (feet cubed) because a sphere is a 3D object, so its volume is also a 3D measurement.

Answer:

-50+12y

Step-by-step explanation:

62+5y-112+7y

62-112+5y+7y

-50+5y+7y

-50+12y

So the question is just asking for you to simplify the inequality until you get an answer.

1. Open the bracket on the left side. If you open it, you get 4x+8 > 8x - 3

2. Know - 4x from both side so you dont have x on 1 side. So 8 > 4x - 3

3. Get rid of the -3 from the right side by adding 3 onto both side. So 11>4x

4. Now you can divide by 4 on each side. x<2.75

= x < 2.75 (x is smaller than 2.75) .

You can write 2.75 > x. It is the same thing but I like writing my x first :)

[tex]\text{D. }44.\overline{4}[/tex]

Step-by-step explanation:

*The person who asked this question clarified answer choice D should be [tex]\text{D. }44.\overline{4}[/tex].

Define a terminating decimal by a decimal that has a finite (or fixed) number of digits. Answer choices A, B, and C all have a finite number of digits, thus they are terminating decimals. The overline is answer choice D is using to represent that digit (4) is repeating and therefore there are an infinite number of digits in the decimal. Thus, [tex]\boxed{\text{D. }44.\overline{4}}[/tex] is not a terminating decimal.

Answer:

4.5 units

Step-by-step explanation:

PQ transferred to WX, and QR to XY.

PQ = 4, WX = 6, so the scaling factor x applies so that we create 6 or of 4 :

4 × x = 6

x = 6/4 = 3/2

the save scaling factor applies now to all other sides too due to the fact that the same transformation was done to the whole shape.

=> QR × 3/2 = XY.

3 × 3/2 = 9/2 = 4.5 = XY

The third term of the given sequence exists 19.

Term to term rule when the sequence [tex]$-2,1,19 \ldots .$[/tex] is reversed will be [tex]$\frac{a-13}{6}$[/tex].

The sequence exists in a particular order in which connected things follow each other.

The term-to-term rule of the sequence stands 6a+13, where a stands for the first term First-term a = -2

Second term b will be [tex]$-2*6+13=1$[/tex]

The rule for the third term will be 6b+13, where b will be the second term. So the third term will be [tex]$6* 1+13=19$[/tex]

So, the sequence will be [tex]$-2,1,19 \ldots \ldots . .$[/tex]

If the order of the above sequence stands reversed, the new sequence will be [tex]$19,1,-2 \ldots \ldots .$[/tex]

If we subtract 13 from first term 19 and then divide by 6 we will get 1 which stands for the second term of the new sequence [tex]$19,1,-2 \ldots \ldots .$[/tex]

So a new term-to-term sequence rule will be [tex]$\frac{a-13}{6}$[/tex] where a stands for the first term.

Therefore, the third term of the given sequence exists 19.

Term to term rule when the sequence [tex]$-2,1,19 \ldots .$[/tex]  exists reversed will be [tex]$\frac{a-13}{6}$[/tex].

Answer:

Step-by-step explanation:

You got it right.

If the polynomial has integer coefficients, then any complex roots with non-zero imaginary part must occur along with their conjugates. If a + bi is a root, then so is a - bi.

The given polynomial would then have at least 6 roots: √2, 2, √2 + i and √2 - i, and 2 + 2i and 2 - 2i. So the minimum degree is (A) 6.
