Answer:

B. No

Step-by-step explanation:

The formula of a number pattern with a common difference is Tn= a +d(n-1), where a is the first term and d is the common difference.

Notice that the numbers decrease by 4 from the previous term. Hence the common difference is -4 in this case.

Tn= 22 -4(n-1)

Tn= 22 -4n +4

Tn= 26 -4n

Let's check to see if the formula is right.

When n=2,

T2= 26 -4(2)

T2= 18

This is correct as the 2nd term in the sequence is 18.

If the number is in the sequence, n would be a whole number since nth term cannot be a fraction/ decimal etc.

When Tn= -204,

-204= 26 -4n

4n= 204 +26

4n= 230

n= 230 ÷4

n= 57.5

Since n is not a whole number, -204 is not in the sequence.

Use the fuction h(x)=5x-2 and t(x) =4x+6 to complete the fuction operations listed below
Pavlova-9 [17]
Part A
(h + t)(x)
(5x - 2 + 4x + 6)(x)   First plug in the numbers
(9x + 4)(x)   Add h(x) and t(x)
(9x² + 4x)   Then multiply it by x
x(9x + 4)   Lastly, simplify x out (I'm including both answers because I don't know whether your questions will ask for either one)
Unsimplified Answer: 9x² + 4x      Simplified Answer: x(9x + 4)

Part B
(h x t)(x)
(5x - 2)(4x + 6)(x)    First step is to of cource, plug in the numbers
(20x² + 30x -8x -12)(x)   Next we multiply h(x) and t(x)
(20x² + 22x -12)(x)     Simplify it a little
(20x³ + 22x² - 12x)    After that, multiply the whole thing by x
(2x)(10x² + 11x - 6)     Simplify 2x out of the equation
(2x)(5x - 2)(2x + 3)    Lastly, simplify the rest
Unsimplified Answer: (20x³ + 22x² -12x)    Simplified Answer: (2x)(5x - 2)(2x + 3)

Part C
h[t(x)]
(5x - 2) [(4x + 6)(x)]    Plug in the numbers
(5x - 2)(4x² + 6x)       Multiply t(x) and x
(20x³ + 30x² - 8x² -12x)    Multiply that by h(x)
(20x³ + 22x² -12x)     Simplify a little... Wait! That looks like the answer to Part B! Perhaps we did something wrong, let's go back and alter the third step
(5x -2)(2x)(2x + 3)     This time, simplify before multiplying oh wait, that's part B's simplified answer, isn't it.
Well, there's a good explanation for this: Part B and Part C are essentially the same equations, just in slightly different orders!
So, it will have the same answers and Part B! (At least, in theory, I'd recommend checking this for yourself too!)
Unsimplified Answer: (20x³ + 22x² - 12x)   Simplified Answer: (2x)(5x-2)(2x+3)

Well, that's a wrap, Parts A, B, and, C with work and explanations; if you find that I made a mistake or did something wrong let me know. I hope this helped, and good luck!

50 POINTS! a shirt that normally costs $30 id on sale for $21.75. What percent of the regular price is the sale price
77julia77 [94]

Answer:

72.5%

Step-by-step explanation:

The fraction is $21.75/$30 = 0.725.

To make this a percentage, multiply by 100%:

... 0.725 × 100% = 72.5%

_____

We assume the question is correct as written: "<u>of</u> the regular price." The answer is the complement of this, 27.5%, if the wording is supposed to be "<u>off</u> the regular price."

--2m + 4n2 for m = -6 and n=-5<br> Evaluate the expression
Tamiku [17]

Answer: 112

Step-by-step explanation:

Since we were given m and n, we plug them into the expression and solve.

-2(-6)+4(-5)²            [exponent]

-2(-6)+4(25)            [multiply]

12+100                     [add]

112

Now, we know that the value of the expression is 112.
